Successful pregnancy outcome following selective uterine artery embolization in a case of perforating gestational trophoblastic neoplasia

Gestational trophoblastic neoplasia (GTN) includes a range of premalignant and malignant disorders of trophoblastic tissue. Invasive mole can present as a surgical emergency with rapidly progressive and highly vascular trophoblasts causing uterine perforation. Often hysterectomy is resorted to as a life-saving measure but in women desirous of future fertility, other options should be considered. We present the case of a nulliparous woman who presented with hemoperitoneum following perforating GTN. She was pale with stable vitals. Serum beta hCG at presentation was 98,156IU/L. Ultrasound pelvis revealed a highly vascular heterogenous hypoechoic mass of 5.8cm×5.5cm×6.5cm in the region of fundus and anterior myometrium showing significant internal and peripheral vascularity and displacing endometrium posteriorly. Ultrasound guided tap revealed hemoperitoneum. We decided for uterine artery embolization following clinical stabilization of the patient followed by chemotherapy. Figure 1 shows CT angiography done prior to uterine artery embolization. She conceived spontaneously two years later and was followed up closely in antenatal period. She was induced at 38 completed weeks due to oligohydramnios and decreased fetal movements and vaginally delivered a healthy baby with no postnatal complications. Fertility sparing procedures should be considered as a first possible option in selective cases. Multidisciplinary approach in high-risk cases is a key to optimal outcome.

SynNotch-Programmed Macrophages for Cancerous Cell Detection and Sensing.

Synthetic Notch (synNotch) receptors have enabled mammalian cells to sense extracellular ligands and respond by activating user-prescribed transcriptional programs. Based on the synNotch system, we describe a cell-based in vivo sensor for cancerous cell detection. We attempted to engineer synNotch-programmed macrophages to sense cancer cells via urinary analysis of human chorionic gonadotropin (HCGB5). Principally, when the synNotch receptors of macrophages bind to the ligands of cancer cells, Notch is activated and undergoes intramembrane proteolysis to release the transcriptional activator into the nucleus. The transcriptional activator targets and activates downstream gene expression, such as human chorionic gonadotropin (HCGB5) in macrophages. When HCGB5 is secreted extracellularly into urine, it can be detected with commercial HCGB5 colloidal gold test strips. As a proof of principle, we demonstrated the feasibility of synNotch-programmed macrophages in detecting breast cancer cells engineered with artificial EGFP ligands. We demonstrated that HCGB5 expression was only induced when the cancer cell expressing EGFP ligands is present; thereby, extracellular HCGB5 expression is directly proportional to the number of cancer cells. Further optimizations of the synNotch system can realize the ultimate goal of establishing cell-based in vivo sensors as the paragon of cancer diagnostics for point-of-care testing and home self-test.

Association of Activin A Levels and Body Mass Index with Human CGB (Chorionic Gonadotrophin Beta) in Ectopic Pregnancies and Missed Abortion Patients

Background: An ectopic pregnancy occurs when a fertilized egg implants itself—typically in one of the fallopian tubes—outside of the womb. Connecting the ovaries to the womb are tubes called fallopian tubes. An egg lodged in them won't develop into a baby, and if the pregnancy goes on, it could be dangerous for your health. When symptoms do appear, they usually appear between weeks four and twelve of pregnancy. Missed abortion refers to the clinical state in which there is still an intrauterine pregnancy but it is not progressing normally. Only if the diagnosis of an incomplete abortion or an inevitable abortion was ruled out would the gestation be referred to be a missed abortion. Activin A is a protein that participates principally in reproductive functions. In the adult brain, Neuroprotective effects of activin. Pituitary follicle-stimulating hormone (FSH) release is stimulated by activins, which are separated from gonadal fluids and belong to the The transforming growth factor (TGF-beta) superfamily. Activins are disulfide-linked dimeric proteins. Objectives: To estimate the concentrations in serum of Activin A in women who have been diagnosed with (missed abortion) and ectopic pregnancy, to compare them with non- missed abortion (MA) and ectopic pregnancy (Ep) healthy controls, and to explore the impact of human chorionic gonadotrophin (β-HCG) on the results. Method: The study included 120 participants ranging in age from aged 18-45 years. Thirty of them had Missed abortion and Thirty had ectopic pregnancy were diagnosed by X-ray, whereas sixty were healthy and served as a control group. The Activin A and beta-HcG levels measured by enzyme linked immunosorbent assay method. Body mass index "BMI" was calculated by applying the continuity formula: - Body Mass Index (Kg/m2) = Weight/Height2. Results: Women with ectopic pregnancy and missed abortion had significantly higher levels of ACV-A and human chorionic gonadotropin beta (B-HcG) than the control groups. In addition, patients in the ectopic group had a significantly lower score than patients in the missed abortion group. Conclusion:Serum Activin A can be used as indicators of Ectopic pregnancy and Missed Abortion, Obesity represented by BMI has no significant effect on patients with ectopic pregnancy or missed abortion while Serum Beta-HcG level at cutoff value of >236, ng/ml) may be a novel biomarker for assessment of women with ectopic pregnancy .

Elucidation of the role of XBP1 in the progression of complete hydatidiform mole to invasive mole through RNA-seq

ObjectiveA complete hydatidiform mole (CHM) is a common disease and is known to develop post-molar gestational trophoblast neoplasia (GTN). However, the molecular mechanisms underlying the progression of CHM to post-molar GTN remain largely unknown. In this study, we investigated the molecular factors associated with the progression using RNA-seq. MethodsWe included 13 patients with CHM and performed RNA-seq using freshly frozen samples. We identified differentially expressed genes between patients who developed GTN (GTN group) and those who achieved spontaneous remission after uterine evacuation (SR group), and performed pathway analysis. Then, functional analyses were performed on choriocarcinoma (JAR and JEG-3) and CHM (Hmol1-3B and Hmol1-2C) cells. Moreover, we evaluated the in vivo tumorigenicity of XBP1-overexpressed Hmol1-3B cells. ResultsThe gene expression profiles were separated into two groups, and an upstream regulator analysis was performed using 281 differentially expressed genes. We focused on transcription factors and identified that 33 transcription factors were activated in the GTN group. Then, excluding those with low expression levels in clinical samples and cell lines, XBP1 was selected for further analysis. Additionally, XBP1 downregulation significantly decreased the migration and invasive abilities of choriocarcinoma cells, whereas XBP1 overexpression significantly increased the migration and invasive abilities of CHM cells. Furthermore, animal experiments showed that tumor weight and blood human chorionic gonadotropin (hCG) levels were significantly higher in the XBP1-overexpressing Hmol1-3B-bearing mice than those in the control mice. ConclusionRNA-seq identified XBP1 as a key factor in post-molar GTN, suggesting it contributes to the development of post-molar GTN.

Multiplying Meanings of Pregnancy Through Personal Accounts of Gestational Trophoblastic Disease

In cultures where reproduction is highly medicalised, pregnancy is often understood in terms of foetal development and an anticipated baby. This is connected to a wider privileging of the ‘foetal subject’ in these settings, which has had implications for reproductive autonomy. In this article, I disrupt dominant understandings of pregnancy by engaging with qualitative accounts of gestational trophoblastic disease. This rare condition can entail experiences of pregnancy without foetal development, allowing for scholarly attention to the wider biological, affective and relational constituents of this corporeal event. In this article, I pay particular attention to the ‘pregnancy hormone’ human chorionic gonadotropin (hCG), which in the context of gestational trophoblastic disease becomes a biomarker for disease. My research extends feminist science studies perspectives destabilising understandings of maternal and foetal bodies as bounded and distinct entities. The article de-centres foetal development as the most significant consequence of conception and enriches feminist discussions of reproductive politics.

. Predictive Value of Pre-delivery Serum β-human Chorionic Gonadotropin, Fibrinogen, and Homocysteine for Hypertensive Disorders of Pregnancy

Introduction: it was to investigate the relationship between pre-delivery serumβ-human chorionic gonadotropin (β-HCG), fibrinogen (FIB), and homocysteine (HCY) with hypertensive disorder complicating pregnancy (HDCP). Materials and Methods: 200 HDCP patients and 150 normal pregnant women were selected as study subjects. Fasting cubital venous blood samples were collected to measure serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL), as well as β-HCG, FIB, and HCY levels. Pearson correlation analysis examined relationship between β-HCG, FIB, HCY, and HDCP. Receiver operating characteristic (ROC) curve analysis evaluated the predictive value of these indicators for HDCP. Multiple logistic regression analysis identified risk factors (RFs) for HDCP.Results: serum TG, TC, HDL, LDL, FIB,β-HCG, and HCY were greatly elevated in the HDCP group versus control group (CG) (P<0.05). Serumβ-HCG, FIB, and HCY showed notable positive correlations with HDCP (r = 0.935, 0.547, 0.811; P<0.05), and the areas under the ROC curve (AUC) for predicting HDCP based on serum β-HCG, FIB, HCY, and their combination were 0.743, 0.659, 0.801, and 0.886, respectively (P<0.05). Lipid indicators and serum levels of FIB, β-HCG, and HCY were RFs for HDCP.Conclusion:pregnant women with HDCP exhibited markedly elevated serum lipid levels and FIB, β-HCG, and HCY levels before delivery, which can serve as predictive indicators for HDCP.

Impact of progesterone concentration on hCG trigger day on clinical outcomes with cleavage-stage embryo transfer in in vitro fertilization cycles with an antagonist protocol

Objective: To investigate the impact of the progesterone concentration on human chorionic gonadotropin (hCG) trigger day in fresh cycles versus thawed transfer cycles (the freeze-all strategy) with an antagonist protocol, and to compare the differences in clinical outcomes. Methods: This retrospective cohort study included a total of 2 165 cycles conducted at Henan Provincial People's Hospital with cleavage-stage embryo (at least one top-quality) transfer between January 2017 and December 2023, with serum progesterone levels on hCG trigger day all≤6.34 nmol/L (i.e. 2 ng/ml). Multivariate logsitic regression analysis and curve fitting were performed based on different serum progesterone levels on hCG trigger day [≤3.17 nmol/L (i.e. 1 ng/ml) or 1-2 ng/ml]. Results: Multivariate regression analysis, by using cycle type (either fresh or frozen-thawed cycle) as the exposure variable, showed that the clinical pregnancy rate (≤1 ng/ml: OR=0.93, 95%CI: 0.75-1.14; 1-2 ng/ml: OR=1.05, 95%CI: 0.58-1.87) and live birth rate (≤1 ng/ml: OR=0.90, 95%CI: 0.71-1.13; 1-2 ng/ml: OR=1.53, 95%CI: 0.79-3.00) had no statistically significant differences in group of progesterone concentration ≤1 ng/ml or in group of 1-2 ng/ml. Using serum progesterone levels on hCG trigger day as a continuous variable for curve fitting analysis, the clinical pregnancy rate in fresh or thawed cycles showed no significant changes with increasing progesterone levels. Conclusions: In the antagonist protocol with cleavage-stage embryo transfer (at least one top-quality), when the serum progesterone level on hCG day is ≤2 ng/ml, there are no significant differences in clinical outcomes between thawed cycles and fresh cycles, including clinical pregnancy rate and live birth rate. Transferred in fresh cycles or choosing the freeze-all strategy could be selected based on the actual situation of the patients.

Epithelioid trophoblastic tumor in male patients with germ cell tumor: A clinicopathologic analysis of five cases

Epithelioid trophoblastic tumor (ETT) is an extremely rare chorionic-type neoplasm in the testis, with only seven cases reported in the literature. Here, we report five cases of testicular ETT from a single institution, constituting the largest series of this rare tumor to date. The patients had a mean age of 44 years (range, 20–68 years). Four patients had a previous history of testicular germ cell tumor (GCT) treated with chemotherapy, and they developed ETT in metastatic sites in a mean of 11 years (range, 3–15 years) after the initial diagnosis of testicular GCT. Only one patient had ETT in the testis. Three patients had a normal serum beta–human chorionic gonadotropin (β-hCG) level, and two patients had a level that was slightly elevated, but far below that typically seen in patients with choriocarcinoma. ETT was characterized by a proliferation of intermediate trophoblastic cells with abundant eosinophilic cytoplasm, and the tumors frequently had coagulative necrosis with eosinophilic debris, mimicking keratinizing squamous cell carcinoma. The trophoblastic phenotype of ETT was supported by its immunoreactivity for trophoblastic markers, including GATA-3 (3 of 3 cases tested), α-inhibin (3/4), p63 (3/5), and β-hCG (3/4). ETT was also positive for cytokeratin (4/4) and GCT marker SALL4 (3/3). Despite surgery and chemotherapy, two patients died of disease 17 months after ETT diagnosis, and three patients were alive with metastatic disease at a mean of 20 months (range, 15–28 months). Our results demonstrate that ETT may be an aggressive disease associated with distinct pathologic features and poor clinical outcome.

New tumor markers for testicular cancer - in the here and now and in the future

Germ cell tumors of the testis are the most common tumor entities in young men. Since the introduction of platinum-based chemotherapy in the 1970s, most patients can be cured despite the aggressiveness of germ cell tumors. Optimal serum tumor markers are required for diagnostics, therapy monitoring and aftercare, and these are subject to high requirements. The conventional testicular tumor markers human chorionic gonadotropin (hCG), alpha fetoprotein (AFP) and lactate dehydrogenase (LDH) only meet these requirements with insufficient sensitivity (30-70%). The markers investigated in recent decades, such as PLAP, CEA and NSE, have not become established. Currently, miRNA-371 is being researched in particular. Reliable findings are available for initial staging with significantly better specificities of miRNA-371 compared to conventional tumor markers. Further prospective studies are being conducted for other possible clinical applications, such as follow-up care, therapy monitoring or residual tumors, in order to investigate the revolutionary potential of miRNA-371 in these areas as well. Research is also currently being conducted on circulating tumor cells (CTCs) and cell-free DNA (cfNA) in various areas of application. With regard to germ cell tumors of the testis, however, these analyses are still in their infancy, but it is hoped that this will provide a further sufficient opportunity to use serum tumor markers.

Vaginal cytology during the estrous cycle and early pregnancy of ewes

Changes in vaginal epithelial cells and blood progesterone and estrogen concentrations were compared between estrous cycle and early pregnancy in multiparous Sanjabee ewes. Twenty non-pregnant ewes were synchronized with intravaginal insertion of a controlled internal drug release (CIDR) device which was in place for 7 days, intramuscular administration of a GnRH analog (Alarelin acetate; 12.5 µg) at the time of CIDR insertion (Day -7), a PGF2α analog (D-cloprostenol sodium; 125 µg) and 500 I.U. of human chorionic gonadotropin (hCG) at the time of CIDR removal (Day 0). At Day 0, all ewes were introduced to four fertile rams and observed for estrous signs. Ewes exhibiting estrous signs were divided into two groups: MATED (confirmed pregnant with transrectal ultrasound scanning at Day 35) and NOT-MATED (confirmed non-pregnant with transrectal ultrasound scanning at Day 35). Vaginal smears and blood samples were taken daily and every other day, respectively, from the beginning of estrus for 20 days for cytology and hormone assay. Based on the results, during days 0 and 1 of the estrous cycle, only the percentages of intermediate cells differed between the groups (P < 0.05). During days 2 to 4, there was no difference in the cell populations between the groups (P ≥ 0.05). During days 5 to 16, the percentages of all cell types except the parabasal cells differed between the groups (P < 0.05). During days 17 to 20, the percentages of all types of vaginal epithelial cells differed between the groups (P < 0.05). Progesterone concentrations increased gradually from days 0 to 14 of the estrous cycle in both groups, however, they decreased significantly afterward in the NOT-MATED group. Estrogen concentrations changes showed an opposite pattern to that of progesterone in the study groups. Collectively, vaginal cytology can be used as a useful tool in assessing hormonal and physiological characteristics of the female reproductive system and thus provides a more accurate understanding of the physiology of estrous cycle and early pregnancy in ewes, which can be used to improve reproductive management.

A case report on renal metastasis as an unusual presentation of choriocarcinoma

BackgroundChoriocarcinoma is an aggressively invasive neoplasm, characterized by its rapid proliferation and propensity for metastasis to distant organs via hematogenous dissemination. Lungs (80%), vagina (30%), pelvis (20%), liver (10%), and brain (10%) are the most frequently metastasized organs. Renal metastases are very rare. The clinical manifestations of choriocarcinoma varies depending on the site of disease, making diagnosis challenging. In this report, we provide a clinical case of choriocarcinoma with metastases to the renal and pulmonary systems, displaying symptoms akin to those observed in ectopic pregnancy.Case presentationA 27-year-old female, G2P1, with a previous history of full-term pregnancy in 2018, presented to the hospital with the onset of vaginal bleeding and accompanying abdominal aches. Investigations uncovered a left adnexal mass with a human chorionic gonadotropin (hCG) level of 77,4 mIU/mL and a left pulmonary nodule measuring 31 mm x 21 mm. Laparoscopy was performed due to the high suspicion of an ectopic pregnancy. However, no visible villi were identified during the surgery, and postoperative blood hCG levels continued to rise. A diagnostic curettage also failed to reveal any villi, maintaining the suspicion of a persistent ectopic pregnancy. Following two ineffective courses of methotrexate therapy, the patient was referred to our facility. Prior to her referral, an ultrasound had indicated a mass in the right kidney. However, upon arrival at our hospital, subsequent ultrasonography failed to detect any renal masses. Despite two months of outpatient monitoring, there was a sudden and significant increase in her serum hCG levels. An emergency laparoscopy was performed, revealing no pregnancy-related lesion. After surgery, the patient’s hCG levels dropped dramatically to less than one-tenth of the original amount. Multisite enhanced computed tomography(CT)revealed suspicious lesions in both the renal and pulmonary regions. Upon thorough multidisciplinary consultation, a diagnosis of choriocarcinoma was entertained. Consequently, the patient successfully underwent eight cycles of chemotherapy and has remained recurrence-free for the past year.ConclusionsThis case underscores the potential for choriocarcinoma in women of reproductive age who exhibit radiological signs of renal masses. Early and accurate diagnosis, followed by prompt intervention, is essential to prevent needless surgery procedures.

Boric acid supplementation promotes the development of in vitro-produced mouse embryos by related pluripotent and antioxidant genes.

Boric acid (BA) is an important mineral for plants, animals and humans that assists metabolic function and has both positive and negative effects on biological systems. The present study aimed to investigate the effects of different concentrations of BA added to the culture media, the quality and in vitro development potential of mouse embryos. Superovulated C57Bl6/6j female mice were sacrificed ∼18 hours after human chorionic gonadotropin (hCG) injection. Single-cell-stage embryos were collected from the oviduct, divided into experiment groups and cultured in embryo medium with supplemented BA+ in 5% CO2 at 37 °C until 96 hours at the blastocyst stage. The blastocyst development rates of 0, 1.62 × 10-1, 1.62 × 10-2, 1.62 × 10-3 and 1.62 × 10-4 µM BA were 51.52%, 73.47%, 77.36% and 81.13%, respectively. The in vitro development rates were significantly higher in the 1.62 × 10-3 (p < 0.05) and 1.62 × 10-4 µM BA groups than in the control group (p < 0.001). These results indicated that low BA doses influenced embryo development by positively affecting in vitro development rates, embryo cell numbers, biochemical parameters and development at the molecular level by pluripotent and antioxidant genes. Therefore, BA seems to play an important role on in vitro embryo development.

Does hCG-trigger in the mild stimulation protocol for endometrial preparation have any effect on pregnancy outcome in frozen-thawed embryo transfer?

BackgroundRecent literature has explored the role of human chorionic gonadotropin (hCG) triggering in frozen embryo transfer (FET) cycles with natural endometrial preparation. Despite this, the impact of hCG triggering on pregnancy outcomes following endometrial preparation with mild stimulation (mST) using Letrozole and Gonadotropins remains inadequately characterized. This study aimed to elucidate the effects of hCG-trigger on pregnancy outcomes in mST-FET cycles.MethodsIn the present retrospective cohort study, the pregnancy outcomes of 409 eligible patients who underwent FET cycles with endometrial preparation using a mild ovarian stimulation protocol by letrozole plus low dose gonadotropins at the Royan Institute between 2020 and 2022, were investigated. The study population were segregated into two distinct groups according to type of ovulation: the spontaneous ovulation group (n = 138) and the hCG-trigger group (n = 271). The pregnancy outcomes including implantation and clinical pregnancy rates (CPR) and live birth rates (LBR) were compared between two groups. The multivariable logistic regression was performed to detect the most significant variables related to the LBR in the mST-FET cycles.ResultsDemographic and baseline characteristics were comparable between groups. No significant difference was found in terms of implantation rate (0.65 ± 0.32 vs. 0.60 ± 0.30, P-value: 0.31), CPR (37% vs. 39.7%, P-value: 0.53), and LBR (35.5% vs. 37.3%, P-value: 0.74) in the spontaneous ovulation and hCG-trigger groups, respectively. The logistic regression analysis revealed that only the stage of the transferred embryo exhibited a significant relationship with LBR (blastocyst vs. cleavage: odds ratio (OR); 2.33, 95% confidence interval (CI):1.41–3.86, P-value = 0.001).ConclusionPregnancy outcomes in the mST-FET cycles, including implantation rate, CPR, and LBR are comparable in cycles with or without hCG triggering. Based on the findings from multivariate regression analysis, the sole significant predictive factor for the LBR was the transfer of blastocyst embryos. It is recommended that these results be examined and discussed in future prospective studies with a larger sample size, considering the lack of comparable research in this field.

A case report of late detection of primary mediastinum herm cell tumor

Germ cell tumors are rare malignant neoplasms. Extragondal localization accounts for about 10% of all germ cell tumors, with up to 3% being mediastinal. The low incidence, along with a nonspecific clinical presentation, complicates initial diagnosis and leads to delays in diagnosis and the initiation of specific treatment. Primary care plays a crucial role in detecting such tumors and in patient routing. At the outpatient stage, the patient should be examined and referred to a specialized facility for specific treatment as quickly as possible. For differential diagnosis at the initial stages between mediastinal germ cell tumors and lymphoproliferative diseases, mediastinal sarcomas, thymomas, and others, monitoring tumor markers is necessary: alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (beta-HCG), and lactate dehydrogenase (LDH). When these markers are elevated and time is critical, it is permissible to start specialized antitumor treatment without histological confirmation.Currently, it is also important to consider the role of the new coronavirus infection, which complicates differential diagnosis at the initial stages. This article presents a clinical case of late detection of a germ cell tumor and attempts to conduct systemic therapy in the context of the disease’s complicated progression.

Pregnancy-related hormonal changes and thyroid growth: do they have an impact on the higher incidence of differentiated thyroid cancer in women?

To analyze whether pregnancy could play a role in the higher prevalence of differentiated thyroid carcinoma (DTC) in women. Estrogens strongly modify thyroid economy by increasing iodine clearance, thyroid hormone requirement and production. Human chorionic gonadotropin (hCG) contributes to the increased thyroid hormone synthesis. Both estrogens and hCG can interfere with the regulation of thyroid volume and with thyroid nodule development and progression. The potential effect of hCG is exclusively related to its weak agonistic activity on TSH receptor. Estrogen implication on normal and nodule-derived thyrocyte growth has been demonstrated in vitro and in animal models. Furthermore, there is solid clinical evidence showing a promoting effect of pregnancy on thyroid volume and nodule development. Two metanalysis, one including retrospective and another prospective observational studies, failed to show an association between pregnancy and DTC. A large pooled prospective analysis using multivariable-adjusted Cox proportional hazard models did not demonstrate an association between DTC and parity. Similarly, no association between PTC occurrence and parity was observed in a prospective cohort analysis by linkage to the statewide Surveillance, Epidemiology, and End Results (SEER). The presently available evidence does not support an involvement of pregnancy in DTC etiology.

Effect of progesterone concentration on hCG trigger day on clinical outcomes after high-quality single blastocyst transfer in GnRH antagonist cycles.

To investigate whether progesterone levels on the human chorionic gonadotropin (hCG) trigger day are associated with clinical outcomes in fresh cycles and the first frozen-thawed cycles (the freeze-all strategy) following the transfer of a high-quality single blastocyst. This single-center retrospective analysis was conducted on patients undergoing in vitro fertilization with the gonadotropin-releasing hormone (GnRH) antagonist protocol from January 2017 to December 2023. The study included the first and second oocyte retrieval cycles with progesterone levels ≤2 ng/ml on hCG trigger day. Clinical pregnancy rates and early miscarriage rates were compared among groups using curve fitting, threshold effect analysis, and multivariable regression. When progesterone levels were between 1 and 2 ng/ml, the pregnancy rate in fresh cycles was only 51% of that in cycles with progesterone levels ≤1 ng/ml (95% CI: 0.33, 0.79, p = 0.0028). And the pregnancy rate decreased by 25% (95% CI: 0.51, 1.09) for frozen cycles, although there was no statistically significant (p = 0.1273). When cycle types were used as a binary variable in multivariate regression analysis, it was found that the clinical pregnancy rate in frozen cycles was 1.84 times higher than in fresh cycles (OR = 1.84, 95% CI: 1.38-2.47). For progesterone levels between 1 and 2 ng/ml, the clinical pregnancy rate in frozen cycles was 2.90 times that of fresh cycles (OR = 2.90, 95% CI: 1.59, 5.29, p = 0.0015). Progesterone levels on hCG day had no impact on the clinical pregnancy rate in thaw cycles, nor did they affect miscarriage rates in fresh or thaw cycles (p > 0.05). When progesterone levels on hCG trigger day were between 1 and 2 ng/ml, the clinical pregnancy rate for frozen-thawed cycles of high-quality single blastocyst transfer using an GnRH antagonist protocol significantly surpasses that of fresh cycles, thus elective frozen embryo transfer after the freeze-all strategy is recommended.

Unexpected early pregnancy during myomectomy followed by successful term delivery: A case report.

Leiomyoma, also known as uterine fibroid, is a non-malignant tumor originating from the uterus's smooth muscles. It is the most common benign tumor in the female genital tract, exhibiting varying size and form that can distort the uterus's shape. Uterine fibroids affect 2.7-10.7% of pregnant women and can lead to increased risks during pregnancy, such as miscarriage, placental abruption, preterm labor, and fetal malpresentation. Myomectomy is a surgical intervention for uterine fibroids, but it has drawbacks, including hemorrhage, fever, infection, ureter ligation, adhesive disorders, and unplanned hysterectomy. In this case report, we present a 32-yr-old woman with a large leiomyoma who underwent laparotomy myomectomy due to abdominal pain and heavy menstrual bleeding. 4 wk after the myomectomy, she was referred to the Obstetric Clinic of Ayatollah Taleghani hospital, Tehran, Iran complaining of delayed menstruation. Her beta-human chorionic gonadotropin test was positive. Ultrasound revealed a fetus with an estimated gestational age of 6 wk and 4 days. The pregnancy continued with no complications. At 38 wk of gestation, she underwent a cesarean section and delivered a healthy newborn. This case report supports previous publications that have demonstrated the safety of myomectomy during pregnancy.

Rare forms of ectopic pregnancy in the rudimentary horn and ovary. How not to miss the main thing?

This article presents two cases of ectopic pregnancy in the ovary and rudimentary horn, which had a life-threatening course. Despite availability of modern high-quality diagnostics, determining the condition remains challenging, because the definitive diagnosis is established and confirmed only intraoperatively. Hence, the clinical picture can be used primarily in making a diagnosis and choosing an appropriate treatment strategy. Rare localizations, such as in the ovary and rudimentary horn, which cause difficulties in making a diagnosis, should not be overlooked. If an ectopic pregnancy is not detected promptly and the risks are underestimated, death may occur. Two clinical cases clearly demonstrate timely diagnosis, regardless of additional examination methods (e.g., pelvic ultrasound, human chorionic gonadotropin test), and adequate choice of access and scope of surgical intervention. Moreover, the lack of awareness among women about this type of pathology should be considered. Patients often do not complain, do not remember the date of their last menstruation, do not monitor their menstrual cycle, and do not seek medical help in a timely manner. The combination of several factors can lead to fatal events. In this study, both cases of ectopic pregnancy with a rare localization ended favorably.

8462 Synergistic Outcomes Of hCG And GLP1-RA Combination Therapy: Improved Body Composition And Carbohydrate Metabolism

Abstract Disclosure: F. Comite: None. K. O'Malley: None. Objective: Precision medicine prevents and reverses diseases of aging by way of systematic analysis of body composition and extensive blood biomarkers. Andropause, the age-related reduction of free testosterone (FT) in males, elicits symptoms primarily of muscle loss, decreased libido, and diminished energy. Exogenous testosterone therapy (TTx) subsequently increases lean body mass (LBM) and improves both libido and energy levels in affected males. More recently, stimulation of endogenous testosterone from the testes, human Chorionic Gonadotropin (hCG) has emerged as a compelling physiologic alternative to TTx. Common comorbidities to andropause are DMII and/or obesity. Recent literature surrounds the use of GLP-1 receptor agonists to improve insulin sensitivity in these disorders of carbohydrate metabolism. A primary benefit secondary to GLP-1 use is reduction of fat mass; however, concerns of this monotherapy surround loss of muscle.[1] Remarkably, when treated adjunctly with GLP-1s, hCG therapy significantly mitigates muscle loss while maintaining optimal carbohydrate biomarkers. The efficacy and benefits of hormonal optimization through hCG therapy simultaneous to GLP-1 intervention were investigated. Methods: In this retrospective analysis, a cohort of 20 males ≥30 years of age were reviewed at baseline timepoints and 18 months post treatment-initiation. Participants underwent biweekly hCG and weekly GLP-1 subcutaneous injections. Exclusion criteria restricted use of alternative GLP-1/GIP combination medication. Paired T-Tests were used to determine a relationship between LBM, FT, percent body fat (PBF), fasting glucose (FG), fasting insulin (FI), and HbA1c at each timepoint. Results: Body composition analysis as shown via bioelectrical impedance proved baseline PBF (mean=24.60) significantly reduced post-treatment (p&amp;lt;0.05, mean=18.08) for all participants. In addition, relevant carbohydrate metabolic biomarkers FG, FI, and HbA1c provided significant reductions (p&amp;lt;0.05). Initial FT (mean=67.76) and LBM (mean=150.36) increased significantly at follow-up (p&amp;lt;0.05) with values of 167.55 and 154.91, respectively. Discussion: Using metrics of precision medicine, our interpretation reveals a promising combination therapy for males experiencing andropause. The novel use of hCG to optimize FT levels enhances muscle, while simultaneously, fat loss and reversal of harmful carbohydrate metabolic markers resultant from GLP-1 therapy are achieved. Muscle loss due to overall weight loss is thus ameliorated. Our findings merit further investigation of the magnitude of downstream improvements, particularly in energy and libido.

8764 A Unique Case of Infertility in a Patient with NCCAH

Abstract Disclosure: M. Paravastu: None. R. Patel: None. Background: Non-Classic Congenital Adrenal Hyperplasia (NCCAH) in women often presents with hirsutism, acne, menstrual dysfunction, or infertility. Subfertility in patients with NCCAH can be attributed to menstrual disorders including oligomenorrhea or secondary amenorrhea. We report a unique case in which a patient with NCCAH with consistently normal menstrual cycles is experiencing infertility. Case Description: A 31 y/o female with no PMH was referred to our Endocrinology Clinic for evaluation of Infertility and elevated 17-Hydroxyprogesterone levels (17OHP). Patient has been having trouble conceiving for the past 2 years, no prior successful pregnancies. She started menstrual cycles at age 17, she reports having regular menstrual cycles. Prior to our evaluation, she was seen in Reproductive Endocrinology who completed hormonal and imaging evaluation. Elevated 17OHP: 286ng/dL. Rest of hormonal workup within normal range. Normal Pelvic Ultrasound. Hormonal workup was repeated in our clinic. 17OHP is elevated at 617.01ng/dL. Rest of lab work returned normal with DHEAS:218.9mcg/dL, TSH: 2.826mcUnits/mL, Free Testosterone: 5.4pg/mL, Prolactin:11.7ng/mL, Beta HCG: negative, LH: 13.5mUnits/mL, FSH: 5.3mUnits/mL, Estradiol 79pg/mL. Cosyntropin stimulation test was completed. Baseline AM 17OHP:469.78ng/dL, Baseline Cortisol: 17.9mcg/dL. 17OHP 30 minutes-post:1216.4ng/dL, Cortisol 30 minutes-post: 18.5mcg/dL. 17OHP 60 min-post: 1051ng/dL, Cortisol 60 minutes post:16.4 mcg/dL. Given Inconclusive Cosyntropin stimulation test results, Genetic Testing was recommended. Genetic testing returned positive for NCCAH, patient’s husband is not a carrier of this gene. She was started on Hydrocortisone therapy for treatment of infertility. Shortly after she started on hydrocortisone therapy, patient did successfully conceive, however the pregnancy later resulted in a miscarriage. Conclusion: Subfertility in patients in NCCAH is thought to be due to menstrual irregularities including oligomenorrhea or secondary amenorrhea. We report the first case of a woman with diagnosis of NCCAH who is experiencing infertility despite having normal menstrual cycles. Presentation: 6/1/2024
