Glutathione peroxidase (GPX1) - Selenocysteine metabolism preserves the follicular fluid's (FF) redox homeostasis via IGF-1- NMD cascade in follicular ovarian cysts (FOCs).

Follicular ovarian cysts (FOCs) are characterized by follicles in the ovaries that are >20 mm in diameter and persist for >10 days without the corpus luteum, leading to anovulation, dysregulation of folliculogenesis and subfertility in humans and livestock species. Despite their clinical significance, the precise impact of FOCs on oocyte reserve, maturation, and quality still needs to be explored. While FOCs are observed in both human and livestock populations, they are notably prevalent in livestock species. Consequently, livestock species serve as valuable models for investigating the molecular intricacies of FOCs. Thus, in this study, using goat FOCs, we performed integrated proteomic, metabolomic and functional analyses to demonstrate that oocyte maturation is hampered due to increased reactive oxygen species (ROS) in FOCs follicular fluid (FF) via downregulation of glutathione peroxidase (GPX1), a critical antioxidant seleno enzyme required to negate oxidative stress. Notably, GPX1 reduction was positively correlated with the FF's decline of free selenium and selenocysteine metabolic enzymes, O-phosphoryl-tRNA (Sec) selenium transferase (SEPSECS) and selenocysteine lyase (SCLY) levels. Adding GPX1, selenocysteine, or selenium to the culture media rescued the oocyte maturation abnormalities caused by FOCs FF by down-regulating the ROS. Additionally, we demonstrate that substituting GPX1 regulator, Insulin-like growth factor-I (IGF-1) in the in vitro maturation media improved the oocyte maturation in the cystic FF by down-regulating the ROS activity via suppressing Non-sense-mediated decay (NMD) of GPX1. In contrast, inhibition of IGF-1R and the target of rapamycin complex 1 (mTORC1) hampered the oocyte maturation via NMD up-regulation. These findings imply that the GPX1 regulation via selenocysteine metabolism and the IGF-1-mediated NMD may be critical for the redox homeostasis of FF. We propose that GPX1 enhancers hold promise as therapeutics for enhancing the competence of FOCs oocytes. However, further in vivo studies are necessary to validate these findings observed in vitro.

Perioperative management of a patient with unexpectedly detected early-stage ovarian mucinous carcinoma combined with progressive bulbar paralysis: a case report and literature review.

BACKGROUND: Giant ovarian cysts (GOCs)complicated with progressive bulbar paralysis (PBP) are very rare, and no such literature about these cases have been reported. Through the diagnosis and treatment of this case, the perioperative related treatment of such patients was analyzed in detail, and early-stage ovarian mucinous carcinoma was unexpectedly found during the treatment, which provided reference for clinical diagnosis and treatment of this kind of diseases. CASE PRESENTATION: In this article, we reported a 38-year-old female patient. The patient was diagnosed with PBP 2 years ago. Examination revealed a large fluid-dominated cystic solid mass in the pelvis measuring approximately 28.6×14.2×8.0 cm. Carbohydrate antigen19-9(CA19-9) 29.20 IU/mL and no other significant abnormalities were observed. The patient eventually underwent transabdominal right adnexal resection under regional anesthesia, epidural block. Postoperative pathology showed mucinous carcinoma in some areas of the right ovary. The patient was staged as stage IA, and surveillance was chosen. With postoperative follow-up 1 month later, her CA19-9 decreased to 14.50 IU/ml. CONCLUSIONS: GOCs combined with PBP patients require a multi-disciplinary treatment. Preoperative evaluation of the patient's PBP progression, selection of the surgical approach in relation to the patient's fertility requirements, the nature of the ovarian cyst and systemic condition are required. Early mucinous ovarian cancer accidentally discovered after operation and needs individualized treatment according to the guidelines and the patient's situation. The patient's dysphagia and respiratory function should be closely monitored during the perioperative period. In addition, moral support from the family is also very important.

Predicting nutrition and environmental factors associated with female reproductive disorders using a knowledge graph and random forests.

OBJECTIVE: Female reproductive disorders (FRDs) are common health conditions that may present with significant symptoms. Diet and environment are potential areas for FRD interventions. We utilized a knowledge graph (KG) method to predict factors associated with common FRDs (for example, endometriosis, ovarian cyst, and uterine fibroids). MATERIALS AND METHODS: We harmonized survey data from the Personalized Environment and Genes Study (PEGS) on internal and external environmental exposures and health conditions with biomedical ontology content. We merged the harmonized data and ontologies with supplemental nutrient and agricultural chemical data to create a KG. We analyzed the KG by embedding edges and applying a random forest for edge prediction to identify variables potentially associated with FRDs. We also conducted logistic regression analysis for comparison. RESULTS: Across 9765 PEGS respondents, the KG analysis resulted in 8535 significant or suggestive predicted links between FRDs and chemicals, phenotypes, and diseases. Amongst these links, 32 were exact matches when compared with the logistic regression results, including comorbidities, medications, foods, and occupational exposures. DISCUSSION: Mechanistic underpinnings of predicted links documented in the literature may support some of our findings. Our KG methods are useful for predicting possible associations in large, survey-based datasets with added information on directionality and magnitude of effect from logistic regression. These results should not be construed as causal but can support hypothesis generation. CONCLUSION: This investigation enabled the generation of hypotheses on a variety of potential links between FRDs and exposures. Future investigations should prospectively evaluate the variables hypothesized to impact FRDs.

Hospital-based interventional two-arm parallel comparative study on dydrogesterone vs combined oral contraceptive pills for functional ovarian cysts.

Background: Functional ovarian cysts are common among women of reproductive age, often necessitating medical intervention. This hospital-based interventional study compares the efficacy and safety of combined oral contraceptive pills (COC) and dydrogesterone in managing functional ovarian cysts. Methods: This randomized controlled trial will be conducted over two years at the Department of Obstetrics & Gynecology, AVBRH, Datta Meghe Institute of Medical Sciences. The study population consists of reproductive-age women seeking care at the outpatient unit of Obstetrics and Gynecology at AVBRH hospital. The sample size of 46 participants per group has been calculated based on a 95% confidence interval and the estimated prevalence of functional ovarian cysts. Group A will receive low-dose COC for three menstrual cycles. At the same time, Group B will be administered dydrogesterone (10 mg twice daily) for ten days during the luteal phase, repeated across three cycles. Expected outcomes: The primary outcomes include evaluating the recession of cysts within three months, monitoring alterations in menstrual patterns (frequency, regularity, duration, and volume), assessing the necessary treatment duration, and observing potential side effects (e.g., nausea, vomiting, weight gain, and acne) and complications (e.g., thromboembolism, delayed menstrual cycles post-treatment, and interactions with other drugs). Data analysis will encompass descriptive statistics, comparative tests, and regression models to assess the primary outcomes. The significance level for hypothesis testing will be 0.05 with a two-tailed approach. Registration: CTRI/2023/04/051811.

Udder, Claw, and Reproductive Health in Genomic Selection of the Czech Holstein.

The aim of this study was to construct an enhanced selection index using the genomic and economic parameters of new health disorders and current production and functional traits. Genomic evaluation for the incidence of clinical mastitis (CM), three claw disease traits, retained placenta (RET), metritis (MET), and cystic ovaries (CYS) was performed using linear animal models based on producer-recorded data. Good correlations among the health disorders were found, and their heritability estimates did not exceed 7%. Economic weights (EWs) for the health disorders were EUR -132.10 for CM, EUR -128.87 for overall claw diseases, EUR -52.10 for RET, EUR -80.48 for MET, and EUR -16.16 for CYS. These EWs indicate changes in the present value of the annual profit per cow when increasing the incidence of the traits by one case per cow year. Selection using the enhanced index resulted in favourable responses for most of the new health disorders (e.g., -0.001 and -0.006 cases of RET and MET per cow year, respectively), and also in the current breeding objective traits (+49 kg of milk, -0.02% of calf losses). An index contribution of 7% for the new health disorders was assessed as acceptable for the breeders.

Characteristics of Polycystic Ovary Syndrome: A Case Report Investigating the Role of Kapha and Pitta Doshas.

Polycystic ovary syndrome (PCOS) presents complex challenges in diagnosis and treatment due to its multifactorial nature. This case study focuses on a 31-year-old woman exhibiting symptoms of weight gain, irregular menstruation cycles, and hirsutism, leading to a diagnosis of PCOS. Conventional diagnostic criteria and ultrasound confirmation of multiple ovarian cysts supported the diagnosis. By integrating Ayurvedic principles alongside Western medical techniques, this study sought to address imbalances in the Kapha and Pitta doshas, fundamental energies according to Ayurveda, believed to contribute to PCOS symptoms. Clinical findings emphasized the role of Pitta dosha imbalance in inflammation, hormonal irregularities, and excessive body heat, while Kapha dosha imbalance manifested in fluid retention, weight gain, and increased mucus production. A holistic treatment approach was devised, aiming to restore doshic balance while addressing hormonal and metabolic dysregulation. The treatment protocol comprised lifestyle modifications, advocating for a regular exercise regimen focusing on activities enhancing insulin sensitivity and promoting weight loss. Swimming, yoga, and brisk walking were recommended to achieve these goals. Dietary interventions tailored to balance Kapha and Pitta doshas were prescribed, emphasizing nourishing, warming foods low in carbohydrates to prevent weight gain and boost metabolism. Anti-inflammatory foods, such as turmeric and ginger, were incorporated to mitigate inflammation. The integration of Ayurvedic principles alongside Western medicine offered a comprehensive approach to PCOS management, addressing both the root causes and symptoms of the condition. This personalized treatment strategy aimed not only to alleviate immediate symptoms but also to promote long-term health and well-being by restoring doshic equilibrium and optimizing hormonal and metabolic functions. In conclusion, this case study highlights the potential efficacy of combining Ayurvedic and Western medical approaches in the management of PCOS, offering a tailored and holistic treatment paradigm for patients seeking comprehensive care.

Intervenciones dietéticas en el tratamiento del síndrome del ovario poliquístico. Una revisión bibliográfica / Dietary interventions in the treatment of polycystic ovary syndrome: A bibliographic review

El síndrome del ovario poliquístico (SOP), es una endocrinopatía femenina reconocida como un trastorno heterogéneo caracterizado por un hiperandrogenismo y una disfunción ovulatoria que conlleva problemas de fertilidad. Además, las pacientes suelen presentar una sintomatología asociada como la resistencia a la insulina, la intolerancia a la glucosa, la obesidad central y/o el síndrome metabólico que pueden inducir a un aumento del riesgo de enfermedad cardiovascular. Dado que uno de los principales objetivos del tratamiento del SOP es reducir las consecuencias metabólicas relacionadas con la obesidad, la resistencia a la insulina y el síndrome metabólico, las intervenciones dietéticas dirigidas a este propósito pueden resultar eficaces en el tratamiento de este padecimiento. Se ha llevado a cabo una búsqueda bibliográfica en diferentes bases de datos como Web of Science (WOS), PubMed y Google Académico estableciendo unos criterios de búsqueda previamente definidos. Se han elegido 11 trabajos para su revisión completa y análisis crítico. Entre las diferentes intervenciones que se han utilizado, se han seguido estrategias dietéticas como la Dietary Approaches to Stop Hypertension (DASH), modificaciones en los hidratos de carbono (HC), la inclusión de algún alimento determinado en el patrón dietético habitual y/o los cambios en el estilo de vida. De los resultados obtenidos, destacan las mejoras propiciadas en los marcadores corporales con un régimen DASH, los beneficios promovidos por dietas con modificaciones en los HC, en la resistencia insulínica (IR) y los marcadores hormonales, así como los efectos favorables en las manifestaciones clínicas relacionadas con el hiperandrogenismo, fomentados por el consumo de soja y las modificaciones en el estilo de vida (LSM).(AU)

Polycystic ovary syndrome (PCOS) is a female endocrinopathy recognized as a heterogeneous disorder characterized by hyperandrogenism and ovulatory dysfunction that leads to fertility problems. In addition, patients usually present with associated symptoms such as insulin resistance, glucose intolerance, central obesity and/or metabolic syndrome that can induce an increased risk of cardiovascular disease. Since one of the main goals of PCOS is to reduce the metabolic consequences related to obesity, insulin resistance, and the metabolic syndrome, targeted dietary interventions may be effective in treating PCOS.A bibliographic search has been carried out in different databases such as Web of Science, Pubmed and Google Scholar, establishing previously defined search criteria. Eleven have been chosen for full review and critical analysis. Among the different interventions that have been used, dietary strategies have been followed such as the dietary approaches to stop hypertension (DASH), modifications in carbohydrates, the inclusion of a certain food in the usual dietary pattern and/or lifestyle modifications. Of the results obtained, we highlight the improvements in body markers with a DASH diet, the benefits promoted by diets with modifications in carbohydrates, in insulin resistance and hormonal markers and favorable effects on clinical manifestations related to hyperandrogenism, fostered by soy consumption and lifestyle modifications.(AU)

Effect of Gonadotropin-Releasing Hormone Antagonist on the Expression Patterns of Insulin-Like Growth Factor 1, Androgen Receptor, and Luteinizing Hormone Receptor in an Experimental Rat Model of Functional Ovarian Cysts.

We studied the expression of insulin-like growth factor 1 (IGF-1), androgen receptor (AR) and luteinizing hormone receptor (LHR) in the ovaries under the conditions of the modeling and subsequent treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist (ant-GnRH). The intensity of IGF-1, LHR, and AR expression in the generative elements of rat ovaries changed under conditions of functional ovarian cysts simulation, as well as during treatment with ant-GnRH. In both experimental groups, the expression levels of the studied markers in preantral follicles and epithelial lining of cysts were found to be related to the number of growing follicles and cysts. A divergence of LHR and AR expression indices and a more pronounced decrease in the number of cystic cavities were observed in the group receiving ant-GnRH. These changes demonstrate a positive effect of ant-GnRH on intra-ovarian regulatory factors and a therapeutic effect in functional ovarian cysts.

Morphofunctional State of the Ovaries in Rats with Experimental Model of Functional Cysts and Their Treatment with Gonadotropin-Releasing Hormone Antagonist.

The morphofunctional features of the ovaries were evaluated in rats with functional ovarian cysts model treated with gonadotropin-releasing hormone antagonist. Administration of the antagonist significantly (p=0.009) reduced the number of cysts and the growth of follicles in the ovaries. The obtained results attest to a possibility of successful treatment of functional ovarian cysts with gonadotropin-releasing hormone antagonist.

Effect of Double-Ovsynch and Presynch-Ovsynch on postpartum ovarian cysts and inactive ovary in high-yielding dairy cows.

Introduction: Optimizing the management of dairy cattle reproduction can reduce postpartum ovarian disease in high-yielding dairy cows and thus enhance ranch economic benefit. The hypothesis of this study was that the Double-Ovsynch (DO) protocol in high-producing dairy cows would result in a lower incidence of follicular cysts but a higher incidence of luteal cysts compared to those undergoing the Presynch-Ovsynch (PS) protocol. Methods: In this experiment, 384 cows (204 primiparous and 180 multiparous) were allocated to the DO group, which followed the protocol: GnRH-7d-PGF2α-3d-GnRH-7d-Ovsynch-56 h (GnRH-7d-PGF2α-56 h-GnRH-16hTAI), starting on 39 ± 3 days in milk (DIM). Additionally, 359 cows (176 primiparous and 183 multiparous) were assigned to the PS group, which followed the protocol: PGF2α-14d-PGF2α-12d-Ovsynch-56 h, starting on 31 ± 3 DIM. In DO, B-mode ultrasound examinations were conducted 1 day after the GnRH-7d-PGF2α-3d-GnRH protocol to diagnose the presence of ovarian diseases followed by reexamination after 7 days of suspected cases. In PS, B-mode ultrasound examinations were conducted 1 day after the PGF2α-14d-PGF2α protocol to diagnose the presence of ovarian diseases followed by reexamination after 7 days. For all cows confirmed to having ovarian diseases, a second B-mode ultrasound examination was conducted at the time of the second GnRH and timed artificial insemination (TAI). If the ovary showed a normal developing follicle in combination with normal ovulation, the ovarian disease was considered to be cured. Results: The current study revealed no significant difference in the overall incidence and cure rate of postpartum ovarian diseases between DO and PS (incidence rate: 3.9% vs. 6.7%, cure rate: 50% vs. 41.7%, DO vs. PS). Also, there was no significant difference in the incidence and cure rate of luteal cysts between DO and PS (incidence rate: 2.9% vs. 2.2%, cure rate: 50.0% vs. 50.0%). The incidence of follicular cysts was significantly lower in the DO group than in the PS group (0.8% vs. 2.8%, DO vs. PS, p = 0.037), but there was no significant difference in the cure rates (66.7% vs. 50%). The occurrence of inactive ovary was lower in DO compared to PS (0.2% vs. 1.7%, p = 0.047). There was no significant difference in the pregnancy rate between the DO and PS groups (48.2% vs. 41.8%), although the DO group had a higher rate. What is different from our assumption is that PS did not effectively reduce the incidence of postpartum luteal cysts.

Endometriosis MR mimickers: T1-hyperintense lesions.

Endometriosis is a chronic and disabling gynecological disease that affects women of reproductive age. Magnetic resonance imaging (MRI) is considered the cornerstone radiological technique for both the diagnosis and management of endometriosis. While MRI offers higher sensitivity compared to ultrasonography, it is prone to false-positive results, leading to decreased specificity. False-positive findings can arise from various T1-hyperintense conditions on fat-suppressed T1-weighted images, resembling endometriotic cystic lesions in different anatomical compartments. These conditions include hemorrhage, hyperproteic content, MRI artifacts, feces, or melanin. Such false positives can have significant implications for patient care, ranging from incorrect diagnoses to unnecessary medical or surgical interventions and subsequent follow-up. To address these challenges, this educational review aims to provide radiologists with comprehensive knowledge about MRI criteria, potential pitfalls, and differential diagnoses, ultimately reducing false-positive results related to T1-hyperintense abnormalities.Critical relevance statementMRI has a 10% false-positive rate, leading to misdiagnosis. T1-hyperintense lesions, observed in the three phenotypes of pelvic endometriosis, can also be seen in various other causes, mainly caused by hemorrhages, high protein concentrations, and artifacts.Key points• MRI in endometriosis has a 10% false-positive rate, leading to potential misdiagnosis.• Pelvic endometriosis lesions can exhibit T1-hyperintensity across their three phenotypes.• A definitive diagnosis of a T1-hyperintense endometriotic lesion is crucial for patient management.• Hemorrhages, high protein concentrations, lipids, and artifacts are the main sources of T1-hyperintense mimickers.

Clinical course of peripheral precocious puberty in girls due to autonomous ovarian cysts.

OBJECTIVE: Peripheral precocious puberty (PPP) is the precocious development of secondary sexual characteristics without pulsatile gonadotropin-releasing hormone (GnRH) secretion. In girls, PPP suggests a hyper-oestrogenic state, such as autonomous ovarian cysts and McCune-Albright syndrome (MAS). We aimed to investigate PPP in girls with ovarian cysts, with or without MAS. DESIGN: A retrospective study design was used. PATIENTS AND MEASUREMENTS: The study included 12 girls diagnosed with ovarian cysts with PPP between January 2003 and May 2022. Pelvic sonography was performed in cases of vaginal bleeding or areolar pigmentation in PPP. The clinical characteristics, clinical course and pelvic sonographic findings of girls with ovarian cysts were investigated. RESULTS: We found 18 episodes of ovarian cysts in the 12 girls. The median size of the ovarian cysts was 27.5 mm. Five of the girls were diagnosed with MAS. The median time to spontaneous regression was 6 months. Later, 4 out of 12 girls progressed to central precocious puberty (CPP), and three of them had a recurrence of ovarian cysts. Compared to the non-recurrent and recurrent groups, there was a difference in peak luteinizing hormone (LH) in the GnRH stimulation test and period to cyst regression. CONCLUSIONS: Most ovarian cysts in PPP spontaneously disappear. However, this could be one of the findings of MAS. Some girls progress from PPP to CPP. Therefore, follow-up is necessary for ovarian cysts in patients with PPP. The recurrence of ovarian cysts may occur when spontaneous regression is prolonged.

[Ovarian masses in infants and children]. / Raumforderungen des Ovars im Kindesalter.

BACKGROUND: Abnormalities of the ovary are frequently seen on ultrasound examination, sometimes symptomatic, but are more commonly asymptomatic. PURPOSE: Presentation of the most important entities of ovarian masses and their imaging features in infants and children. Discussion of criteria for differentiation between benign and potentially malignant masses. MATERIALS AND METHODS: Review of current literature and presentation of image examples. RESULTS: The most common lesions are ovarian cysts in infants, which usually do not require therapy. Because of the risk of torsion, surgery should be discussed for lesions with a size of 5 cm or more. Benign teratomas represent three-quarters of all solid tumors of the infantile ovary. Malignant masses are rare. The task of imaging is to assess the potential risk of malignancy, also using imaging scores. CONCLUSIONS: Imaging plays a crucial role for therapeutic considerations. Depending on the potential risk, ovarian-sparing surgery is preferred to preserve fertility, as long as the oncologic risk is reasonable.

[Applicability of the Adnex score in predicting the malignancy of ovarian cysts]. / Applicabilité de l'Adnex score dans la prédiction de la malignité des kystes ovariens.

OBJECTIVE: Ovarian cancer screening is a difficult problem due to the anatomy of the ovaries. Only histology allows a definite diagnosis. Our objective was to study the contribution of the Adnex score in the histological characterization of adnexal images for adequate management. METHODS: It was a retrospective, mono-center, descriptive and analytical. Sixty-five patients were included, those operated for an ovarian cyst and meeting the Adnex criteria: clinical, ultrasound and laboratory. RESULTS: The mean age of the patients was 38.6 years. They were nulliparous in 43 % of cases, and only four had a history of operation on ovarian cyst. Abdominal pelvic pain was the most frequent reason for consultation in 48 % of cases. An abdominopelvic mass was found on abdominal examination in 11 % of cases. Pelvic ultrasound made it possible to objectify the presence of an ovarian mass in all cases, with an average size of 79.66mm and a reassuring appearance in 66 % of cases. The calculation of the Adnex score was done in all patients preoperatively, for a 10 % cut-off, the model showed an 86 % chance of benignity for tumors proven to be histologically benign. The main route of entry was laparoscopy, in 61 % of cases. The treatment was in most cases conservative consisting essentially of a cystectomy. CONCLUSION: The Adnex score discriminated well between benign and malignant masses, allowing for a better diagnosis preoperatively. It thus deserves its applicability in the clinical setting.

Ovarian hydatid cyst: an uncommon site of presentation.

Hydatid cyst is a parasitic infestation caused by Echinococcus larvae. Hydatid cyst of the ovary is a highly unusual presentation. Herein, we present a case of a young woman who complained of episodic lower abdominal pain. Ultrasound of the abdomen revealed a multi-cystic left adnexal mass measuring 86 mm x 67 mm. A possibility of ovarian cystic neoplasm was suggested. Unilateral salpingo-oophorectomy was performed. On histopathological examination, a cyst measuring 8.0 x 5.5 x 4.5 cm was found, replacing the entire ovary. The cyst cavity was filled with serous fluid and multiple pearly white membranous structures, giving a multiloculated appearance. Microscopic examination showed a cyst lined by a lamellar membrane containing protoscolices and hooklets. Hydatid disease is a zoonotic ailment caused by tapeworms (Echinococcus granulosus or, less commonly, Echinococcus multilocularis). The definitive hosts are carnivores. Humans are the accidental intermediate hosts. The hydatid cyst commonly affects the liver and the lungs. The primary hydatid cyst of the ovary is quite rare, with few case reports in the literature. In most cases, symptoms are vague, and the lesion is misdiagnosed as benign or malignant ovarian cystic neoplasm on clinical and radiological examination. Ovarian hydatid cyst is treated by surgery with ovarian cystectomy as the gold standard. The possibility of a hydatid cyst should be kept under differential diagnoses while evaluating the cystic diseases of the ovary.

Mammoth Bilateral Ovarian Serous Cyst Adenomas in a Postmenopausal Woman: A Rare Case Report.

Serous cyst adenomas account for about 40% of all ovarian tumors and most commonly are diagnosed in middle-aged women. The aim of this publication is to present an extremely rare case of mammoth bilateral cyst adenomas in a postmenopausal woman, occupying the pelvis and the most of abdominal cavity. A 67-year-old obese woman was presented to our emergency department with abdominal pain. Ultrasound and computed tomography of the abdomen verified two huge cystic masses. Exploration of the abdominal cavity by laparotomy established two intact giant cystic masses with ovarian origin. The cysts were removed by bilateral salpingo-oophorectomy and hysterectomy was performed. Histological examination revealed that both cystic masses were ovarian serous cyst adenomas. The woman was discharged with an uneventful recovery. We present a case of the largest gigantic bilateral ovarian cyst adenomas in the oldest woman ever reported.

Predicting nutrition and environmental factors associated with female reproductive disorders using a knowledge graph and random forests.

Objective: Female reproductive disorders (FRDs) are common health conditions that may present with significant symptoms. Diet and environment are potential areas for FRD interventions. We utilized a knowledge graph (KG) method to predict factors associated with common FRDs (e.g., endometriosis, ovarian cyst, and uterine fibroids). Materials and Methods: We harmonized survey data from the Personalized Environment and Genes Study on internal and external environmental exposures and health conditions with biomedical ontology content. We merged the harmonized data and ontologies with supplemental nutrient and agricultural chemical data to create a KG. We analyzed the KG by embedding edges and applying a random forest for edge prediction to identify variables potentially associated with FRDs. We also conducted logistic regression analysis for comparison. Results: Across 9765 PEGS respondents, the KG analysis resulted in 8535 significant predicted links between FRDs and chemicals, phenotypes, and diseases. Amongst these links, 32 were exact matches when compared with the logistic regression results, including comorbidities, medications, foods, and occupational exposures. Discussion: Mechanistic underpinnings of predicted links documented in the literature may support some of our findings. Our KG methods are useful for predicting possible associations in large, survey-based datasets with added information on directionality and magnitude of effect from logistic regression. These results should not be construed as causal, but can support hypothesis generation. Conclusion: This investigation enabled the generation of hypotheses on a variety of potential links between FRDs and exposures. Future investigations should prospectively evaluate the variables hypothesized to impact FRDs.

[Pseudoascitis by giant ovaric cyst] / Pseudoascitis por quiste ovárico gigante.

The term pseudoascitis is used in patients who give the false impression of ascites, with abdominal distension but without peritoneal free fluid. The case of a 66-year-old woman, hypertensive and hypothyroid with occasional alcohol consumption, who consults due to progressive abdominal distension of 6 months of evolution and diffuse percussion dullness is presented, in whom a paracentesis is performed with the wrong endorsement of examination ultrasound that reports abundant intrabdominal free fluid (Fig. 1), later finding in the CT scan of the abdomen and pelvis an expansive process of cystic appearance of 295mm x 208mm x 250mm. Left anexectomy is programmed (Fig. 2) with pathological report of mucinous ovarian cystadenoma. The case report refers to the availability of the giant ovarian cyst within the differential diagnosis of ascites. If no symptoms or obvious signs of liver, kidney, heart or malignant disease are found and / or ultrasound does not reveal typical signs of intra-abdominal free fluid (fluid in the bottom of the Morrison or Douglas sac, presence of floating free intestinal handles), a CT scan and / or an RMI should be requested before performing paracentesis, which could have potentially serious consequences.

El término pseudoascitis, se utiliza en los pacientes que dan la falsa impresión de ascitis, con distensión abdominal pero sin líquido libre peritoneal. Se presenta el caso de una mujer de 66 años, hipertensa e hipotiroidea con consumo ocasional de alcohol, que consulta por distensión abdominal progresiva de 6 meses de evolución y matidez difusa a la percusión, en quien se realiza una paracentesis con el aval equivoco de examen ecográfico que informa abundante líquido libre  intrabdominal (Fig. 1), hallando posteriormente en TAC de abdomen y pelvis un proceso expansivo de aspecto quístico de 295mm x 208mm x 250mm. Se programa anexectomia izquierda (Fig. 2) con informe anatomopatológico de cistoadenoma mucinoso de ovario. La comunicación del caso remite a tener disponible el quiste ovárico gigante dentro de los diagnósticos diferenciales de ascitis. Si no se hallan síntomas o signos evidentes de insuficiencia hepática, renal, cardiaca o enfermedad maligna y/o la ecografía no revela signos típicos de líquido libre intrabdominal  (líquido en el fondo de saco de Morrison o de Douglas, presencia de asas intestinales libres flotantes), se debería solicitar una TAC y/o una RMI antes de realizar una paracentesis, la cual podría tener consecuencias potencialmente graves.
