RESUMEN

MicroRNAs (miRs) play an important role in the pathophysiology of endometriosis; however, the role of miR-210 in endometriosis remains unclear. This study explores the role of miR-210 and its targets, IGFBP3 and COL8A1, in ectopic lesion growth and development. Matched eutopic (EuE) and ectopic (EcE) endometrial samples were obtained for analysis from baboons and women with endometriosis. Immortalized human ectopic endometriotic epithelial cells (12Z cells) were utilized for functional assays. Endometriosis was experimentally induced in female baboons (n = 5). Human matched endometrial and endometriotic tissues were obtained from women (n = 9, 18-45 years old) with regular menstrual cycles. Quantitative reverse transcript polymerase chain reaction (RT-qPCR) analysis was performed for in vivo characterization of miR-210, IGFBP3, and COL8A1. In situ hybridization and immunohistochemical analysis were performed for cell-specific localization. Immortalized endometriotic epithelial cell lines (12Z) were utilized for in vitro functional assays. MiR-210 expression was decreased in EcE, while IGFBP3 and COL8A1 expression was increased in EcE. MiR-210 was expressed in the glandular epithelium of EuE but attenuated in those of EcE. IGFBP3 and COL8A1 were expressed in the glandular epithelium of EuE and were increased compared to EcE. MiR-210 overexpression in 12Z cells suppressed IGFBP3 expression and attenuated cell proliferation and migration. MiR-210 repression and subsequent unopposed IGFBP3 expression may contribute to endometriotic lesion development by increasing cell proliferation and migration.

RESUMEN

New family configurations are emerging concurrently with improved assisted reproduction techniques, including the use of donated gametes. Most indications for treatment when using donated eggs are caused by an age-related decrease in reproductive capacity. We evaluated the emotional state regarding accepting egg donation in participants who chose this option for in vitro fertilization cycles. This is a retrospective, Brazilian cohort study, based on data collected from sixty psychological counseling sessions with participants that opted to be enrolled in an egg donation program. A single professional conducted semi-structured psychological counselling sessions. The data were analyzed using a thematic analysis as the qualitative methodology. Two years after the psychological counseling sessions, participants were contacted to obtain information about their outcomes. Of 60 sessions, 19 (32%) were classified as involving participants with positive emotional state (group 1), 14 (23%) with unfavorable emotional state (group 2), and 27 (45%) without evident classification (group 3). Three couples did not undergo treatment until two years after the psychological counselling session and the other couples underwent treatment in a period ranging from 1-8 months after the session. This is the first study in the Brazilian population regarding the acceptance of egg donation. The process of acceptance of infertility and the impossibility to have a biological child is fundamental to gradually accepting a new way of becoming a parent. Psychological counseling can contribute to reflecting on the use of donated eggs, exploring its emotional implications and identifying the need for psychotherapeutic work to address conflict and suffering.

RESUMEN

During embryo implantation, endometrial angiogenesis is regulated by signals originating from the endometrium itself and the developing embryo. It has been suggested that hCG may play a pro-angiogenic role; therefore, we sought to understand its regulatory role in blood vessel formation in human endometrium using in vivo and in vitro models. In the in vivo model, we screened 16 angiogenesis-related transcripts in the endometrium upon intrauterine administration of hCG. Oocyte donors were recruited and during their controlled ovarian stimulation cycle received a single dose of hCG or vehicle on the day of oocyte pick up during a cycle of ovarian stimulation. One hour before obtaining an endometrial sample, women received an intrauterine administration of vehicle or hCG (500, 1500 and 5000 IU). Transcript and protein analysis showed that MMP3 and VEGFA increased, whereas TIMP1 decreased. The in vitro analysis studied the angiogenic potential of conditioned medium (CM) from primary cultures of human endometrial stromal cells (ESC) stimulated with hCG. Using a 2D and 3D in vitro angiogenesis assays, our results indicate that CM from ESC almost completely inhibits the capillary-like structure formation in endothelial cells, overriding the pro-angiogenic effect of hCG; and this inhibition due to secreted factors present in CM specifically reduced the migration potential of endothelial cells. In conclusion, the endometrial stromal milieu seems to modulate the direct pro-angiogenic effects of hCG on endothelial cells during embryo implantation.

RESUMEN

A 26-year-old patient was admitted in our center with one year of infertility history after a miscarriage. She was diagnosed with uterus bicornis unicollis and deep infiltrating endometriosis (DIE); therefore, she underwent endometriosis focus removal surgery. After six-months, she conceived spontaneously and delivered one healthy baby. One year after the first pregnancy delivery, she conceived spontaneously and delivered twins in an extremely rare condition of uterus bicornis unicollis, of which there are only 15 cases reported worldwide. Both pregnancies were monitored every two or three weeks using ultrasonography to assess fetal growth, and cervical length was measured to assess the risk of premature delivery.

RESUMEN

Deeply infiltrative endometriosis (DIE) is a common gynecologic disease affecting women of reproductive age and often causing chronic pelvic pain and infertility. Clinical treatment options and preventive actions are ineffective due to the lack of knowledge about the etiology of DIE. Surgical treatment is currently the only alternative to eradicate the disease. Diagnostic imaging plays a crucial role for surgical planning and postoperative evaluation. Transvaginal sonography (TVS) with a dedicated protocol and magnetic resonance imaging (MRI) can be used to evaluate recurrent disease. Extensive pelvic surgery may cause anatomical changes and a variable spectrum of postoperative findings. Residual disease and complications can be also evaluated and are of great importance to estimate pain relief and fertility prognosis. The most common imaging findings following radical surgery for DIE are fibrotic scars in the retrocervical space and bowel anastomosis, absence of the posterior vaginal fornix and loculated fluid in the pararectal spaces. Ovaries are the most frequent site of early recurrence. Complications include infection, hemorrhage, urinary/evacuatory voiding dysfunctions as well as bowel and ureteral stenosis. The purpose of this article is to review the surgical techniques currently used to treat endometriosis in the retrocervical space, vagina, bladder, bowel, ureters, and ovaries and to describe the most common imaging findings including normal aspects, residual disease, complications, and recurrence.

RESUMEN

Fertility preservation in the cancer setting, known as oncofertility, is a field that requires cross-disciplinary interaction between physicians, basic scientists, clinical researchers, ethicists, lawyers, educators, and religious leaders. Funded by the National Institutes of Health, the Oncofertility Consortium (OC) was formed to be a scientifically grounded, transparent, and altruistic resource, both intellectual and monetary, for building this new field of practice capable of addressing the unique needs of young patients with cancer. The OC has expanded its attention to include other nonmalignant conditions that can threaten fertility, and the work of the OC now extends around the globe, involving partners who together have created a community of shared effort, resources, and practices. The OC creates materials that are translated, disseminated, and amended by all participants in the field, and local programs of excellence have developed worldwide to accelerate the pace and improve the quality of oncofertility research and practice. Here we review the global oncofertility programs and the capacity building activities that strengthen these research and clinical programs, ultimately improving patient care.

RESUMEN

BACKGROUND: To evaluate human papillomavirus (HPV), Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in juvenile idiopathic arthritis (JIA) patients. METHODS: After exclusion, 33 female adolescent and young JIA patients (ILAR criteria) and 28 healthy controls were selected for this study. Demographic data, gynecological, sexual function, cervical cytology and histological abnormalities were evaluated. JIA clinical/laboratorial parameters and treatment were also assessed. HPV-DNA, CT-DNA and NG-DNA testing in cervical specimens were performed by Hybrid Capture 2 assays. RESULTS: The mean current age was similar in JIA patients and controls (23.3 ± 6.24 vs. 26.1 ± 6.03 years, p = 0.09). The frequencies of sexual intercourse (76% vs. 89%, p = 0.201) and abnormal cervical cytology (24% vs. 11%, p = 0.201) were similar in JIA compared to controls. The higher frequency of HPV infection in JIA patients than controls (30% vs. 11%, p = 0.155) did not reach statistical significance. CT (0% vs. 7%, p = 0.207) and NG infections (0% vs. 4%, p = 0.459) were also alike in both groups. Further evaluation of JIA patients with abnormal and normal cervical cytology showed that the former group had a higher frequency of HPV infection (87% vs. 12%, p = 0.0002) with a low frequency of HPV vaccination (0% vs. 8%, p = 1.0). No differences were evidenced between these two JIA groups regarding demographic data, sexual function and clinical/laboratorial parameters. The frequencies of methotrexate (p = 0.206) and biological agent use (p = 0.238) were similar in both JIA groups. CONCLUSIONS: To our knowledge, this was the first study to assess lower genital infections in JIA patients allowing the identification of HPV as main cause of cervical dysplasia. Methotrexate and biological agents do not seem to increase risk of lower genital tract infections in JIA patients.

RESUMEN

OBJECTIVE: To evaluate prognostic factors for pregnancy after intrauterine insemination (IUI). METHODS: A retrospective study was conducted among couples who underwent IUI at Universidade de São Paulo, Brazil, between January 31, 2008, and April 30, 2016. The main outcome was a positive ß human chorionic gonadotropin (ß-hCG) test result after IUI. Univariate analyses were used to determine predictors of pregnancy. Selected numerical variables were categorized to maximize the area under the receiver operating characteristic (ROC) curve. Logistic regression was performed using the backward method. The quality of the model was evaluated using the R2 (Nagelkerke) and Hosmer-Lemeshow tests. RESULTS: Of 355 insemination cycles, 56 (15.8%) resulted in a positive ß-hCG test result. The predictors and cutoff values that maximized the area under the ROC curve were as follows: follicle-stimulating hormone (<7.7 mIU/mL; P<0.001); duration of infertility (<62 menses; P<0.001); number of follicles greater than or equal to 14 mm (>1 follicle; P<0.001); baseline spermatozoa concentration (>52.0 million/mL; P=0.007); total ejaculate (>123.7 million; P=0.003); and grade B motility (>35%; P=0.013). These factors were able to predict 50.4% of the positive test results (R2 ). CONCLUSION: Prognostic factors for pregnancy identified approximately half of all successful outcomes after IUI.

RESUMEN

Endometrium extracellular matrix provides a wide range of signals at different cellular levels, like cell death and proliferation, which can be important for regulating menses and reducing the proliferative processes. The objective of this study is to evaluate hyaluronic acid concentration, the enzymes of hyaluronic acid synthases in the endometrium of patients with polycystic ovary syndrome (PCOS) and eumenorrheic women. A total of 60 endometrial samples from 30 patients with PCOS and 30 women with regular menstrual cycles in the proliferative phase, attended at Gynecology Division of Clinical Hospital of the FMUSP (HC-USP). Profile determination and the concentration of hyaluronic acid was performed by the biochemical method of the fluorimetric assay (ELISA-like). Its location in the endometrial tissue as well as the dosage of enzymes synthases (HAS1, HAS2 and HAS3) was done by immunohistochemistry and western blotting. Statistical analyses were performed with one-way ANOVA, followed by the Bonferroni test. Regarding hyaluronic acid synthases, there was a higher HAS1 and HAS2 reactivity and lower HAS3 reactivity in the PCOS endometrium compared to women with regular menstrual cycles in the proliferative phase. We suggest that PCOS patients have different composition of hyaluronic acid in relation to a regular cycle in the proliferative phase.

RESUMEN

OBJECTIVES: Juvenile idiopathic arthritis (JIA) occurs during reproductive age, however, there are no systematic data regarding ovarian function in this disease. METHODS: Twenty-eight post-pubertal JIA patients and age-matched 28 healthy controls were studied. Complete ovarian function was assessed during the early follicular phase of the menstrual cycle including anti-Müllerian hormone (AMH), estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and antral follicle count (AFC) by ovarian ultrasound, and anti-corpus lutheum antibodies (anti-CoL). Demographic data, menstrual abnormalities, disease parameters and treatment were also evaluated. RESULTS: The mean current age (22.6 ± 6.59 vs. 22.5 ± 6.59 years, p = .952) was similar in JIA patients and healthy controls with a higher median menarche age [13(8-16) vs. 12(8-14) years, p = .029]. A lower median AMH levels [2.65(0.47-9.08) vs. 4.83(0.74-17.24) ng/mL, p = .029] with a higher LH [8.44 ± 4.14 vs. 6.03 ± 2.80 IU/L, p = .014] and estradiol levels [52.3(25.8-227.4) vs. 38.9(26.2-133.6) pg/mL, p = .008] were observed in JIA compared to control group. Anti-CoL and AFC were similar in both groups (p > .05). Further analysis of JIA patients revealed that current age, disease duration, number of active/limited joints, ESR, CRP, patient/physician VAS, JADAS 71, DAS 28, CHAQ, HAQ, patient/parents PedsQL, PF-SF 36, cumulative glucocorticoid and cumulative methotrexate doses were not correlated with AMH, FSH, estradiol levels or AFC (p > .05). CONCLUSION: The present study was the first to suggest diminished ovarian reserve, not associated to hypothalamic pituitary gonadal axis, in JIA patients during reproductive age. The impact of this dysfunction in future fertility of these patients needs to be evaluated in prospective studies.

RESUMEN

PURPOSE: Controlled ovarian stimulation is a fundamental part of a successful assisted reproduction treatment, and recognizing patients at risk of a poor response allows the development of targeted research to propose new treatment strategies for this specific group. The objective of this systematic review was to determine risk factors for poor ovarian response (POR) to controlled stimulation in assisted reproduction cycles described in the literature. METHODS: The primary databases MEDLINE, Cochrane, LILACS, and SciELO were consulted, using specific terms with a restriction for articles in English or Portuguese published in the last 10 years. RESULTS AND CONCLUSION: Our data suggest that environmental endocrine disruptors, tobacco, genetic mutations, endometriomas, ovarian surgery, chemotherapy, and short menstrual cycles are factors that influence stimulation in assisted reproduction cycles. Further studies are necessary for characterizing patients with prior risk factors.

RESUMEN

BACKGROUND: Uterus transplantation from live donors became a reality to treat infertility following a successful Swedish 2014 series, inspiring uterus transplantation centres and programmes worldwide. However, no case of livebirth via deceased donor uterus has, to our knowledge, been successfully achieved, raising doubts about its feasibility and viability, including whether the womb remains viable after prolonged ischaemia. METHODS: In September, 2016, a 32-year-old woman with congenital uterine absence (Mayer-Rokitansky-Küster-Hauser [MRKH] syndrome) underwent uterine transplantation in Hospital das Clínicas, University of São Paulo, Brazil, from a donor who died of subarachnoid haemorrhage. The donor was 45 years old and had three previous vaginal deliveries. The recipient had one in-vitro fertilisation cycle 4 months before transplant, which yielded eight cryopreserved blastocysts. FINDINGS: The recipient showed satisfactory postoperative recovery and was discharged after 8 days' observation in hospital. Immunosuppression was induced with prednisolone and thymoglobulin and continued via tacrolimus and mycophenalate mofetil (MMF), until 5 months post-transplantation, at which time azathioprine replaced MMF. First menstruation occurred 37 days post-transplantation, and regularly (every 26-32 days) thereafter. Pregnancy occurred after the first single embryo transfer 7 months post-transplantation. No blood flow velocity waveform abnormalities were detected by Doppler ultrasound of uterine arteries, fetal umbilical, or middle cerebral arteries, nor any fetal growth impairments during pregnancy. No rejection episodes occurred after transplantation or during gestation. Caesarean delivery occurred on Dec 15, 2017, near gestational week 36. The female baby weighed 2550 g at birth, appropriate for gestational age, with Apgar scores of 9 at 1 min, 10 at 5 min, and 10 at 10 min, and along with the mother remains healthy and developing normally 7 months post partum. The uterus was removed in the same surgical procedure as the livebirth and immunosuppressive therapy was suspended. INTERPRETATION: We describe, to our knowledge, the first case worldwide of livebirth following uterine transplantation from a deceased donor in a patient with MRKH syndrome. The results establish proof-of-concept for treating uterine infertility by transplantation from a deceased donor, opening a path to healthy pregnancy for all women with uterine factor infertility, without need of living donors or live donor surgery. FUNDING: Fundação de Amparo à Pesquisa do Estado de São Paulo and Hospital das Clínicas, University of São Paulo, Brazil.

No differences were evidenced between these two JIA groups regarding demographic data, sexual function and clinical/laboratorial parameters. The frequencies of methotrexate (p =0.206) and biological agent use (p =0.238) were similar in both JIA groups. Conclusions: To our knowledge, this was the first study to assess lower genital infections in JIA patients allowing the identification of HPV as main cause of cervical dysplasia. Methotrexate and biological agents do not seem to increase risk of lower genital tract infections in JIA patients.

RESUMEN

To assess prospectively luteinized unruptured follicle (LUF) syndrome in juvenile idiopathic arthritis (JIA) patients with and without non-steroidal anti-inflammatory drugs (NSAIDs) and healthy controls. Twenty-three adolescent and young adult female JIA patients (ILAR criteria) and 11 female healthy subjects were studied by pelvic ultrasound monitoring for follicular development and ovulation in one menstrual cycle. LUF syndrome was prospectively investigated by pelvic ultrasound with a dominant ovarian follicle without signs of follicular rupture, with elevation of serum progesterone in the luteal phase of the menstrual cycle and luteinizing hormone (LH) detected in the urine. Comparison between JIA patients with (n = 8) vs. without NSAIDs (n = 15) and healthy controls (n = 11) revealed that LUF syndrome was significantly higher in the former group (2 (25%) vs. 0% vs. 0%, p = 0.049). These two patients with LUF syndrome had normal menstrual cycles without reduced ovarian reserve, and they were under naproxen 500 mg bid during the menstrual cycle. Disease duration was comparable in JIA with and without NSAIDs [19.8 (4.4-25) vs. 13 (3.1-33) years, p = 0.232]. Further comparison between JIA patients with and without NSAIDs and healthy controls showed similar mean anti-Müllerian hormone levels (p = 0.909), estradiol (p = 0.436), FSH (p = 0.662), LH (p = 0.686), and mean antral follicle count (p = 0.240) and ovarian volume (p = 0.363). No differences were evidenced in three groups regarding Caucasian race, body mass index, duration, and length of menstrual cycles (p > 0.05). This is the first study to identify that JIA patients have a high frequency of LUF without impaired ovarian reserve. Future prospective studies are necessary to determine if chronic/continuous use of NSAIDs in JIA will have an impact in these patients' fertility.

RESUMEN

OBJECTIVE: To select embryos with higher implantation potential, the extended culture has been the most frequently applied strategy worldwide, and consequently leads to higher live birth rates per transfer. Sperm quality is a determining feature, and it may influence the outcomes of IVF from fertilization to embryo development. Therefore, we hypothesize that blastocyst formation may also be impaired by general semen quality. METHODS: We analyzed 4205 IVF cycles. Four study groups were designed according to semen quality: normal, mild alteration, severe alteration and epididymis. All cycles were intended to extend embryo culture until the blastocyst stage, and embryo development was evaluated. RESULTS: Regarding cleavage rate, the normal and mild alteration semen groups were equivalent, and the severe alteration and epididymis semen groups were equivalent to each other. The blastocyst formation rate decreased with semen quality. At least one blastocyst formed in 79.9% of cycles for the normal semen group, whereas the percentage of cycles with the formation of at least one blastocyst was slightly lower for the mild alteration (75.6%), severe alteration (76.4%) and epididymis (76.8%) semen groups. A multivariate logistic regression showed that for each additional cleaved embryo on day 3, the chance of having at least one blastocyst doubles. Additionally, the chance of having at least one blastocyst decreased when semen presented mild or severe alterations. CONCLUSION: The general quality of sperm is a good predictor of blastocyst formation, significantly affecting the likelihood of having at least one blastocyst at the end of the cycle. Based on our findings, it is necessary to consider general semen quality and the number of cleaved embryos when forecasting the possibility of blastocyst formation and transfer in an extended culture system.

RESUMEN

INTRODUCTION: Assisted reproductive technologies (ARTs) are associated with potential risks, mainly related to multiple pregnancies, which are around 20% to 25%. Iatrogenic multiple pregnancies due to ovarian stimulation with multiples embryos transferred can be avoided by the elective single-embryo transfer (eSET), a growing practice worldwide. Adequately applied eSET, which impact on the incidence of complications without compromising treatment success, is still a challenge. The aim of this study was to compare the cumulative success rates of elective transfer of 2 embryos when transferred one by one (eSET), versus the success rates of elective double-embryo transfer (DET) in a single procedure, in a good prognosis population. METHODS: This study evaluated 610 good prognosis infertile couples undergoing ART, split into 2 groups: eSET group which included those receiving first eSET (n = 237) and for those who did not become pregnant, they could receive a second frozen-thawed SET; and eDET group (n = 373) who received elective transfer of 2 good quality embryos in the first transfer. RESULTS: Clinical pregnancy outcomes after a transfer of 2 embryos were similar between the groups (DET: 46.6% vs accumulated SET: 45.9%; P = .898). Multiple pregnancy rate was significantly lower in the group receiving transfer of 2 embryos, one by one, compared to DET (DET: 32.2% vs accumulated SET: 6.7%; P < .001). CONCLUSIONS: The eSET policy should be stimulated for good prognosis couples, as it maintains the accumulated clinical pregnancy rates, avoids multiples pregnancies, and consequently the maternal and neonate complication and indirect costs of treatment when considering spending on the obstetrics are reduced.

RESUMEN

PURPOSE: The risk of ovarian failure after radiotherapy and/or chemotherapy is a concern among oncologic women. There is no doubt regarding the psycho-emotional benefits of fertility preservation (FP) after a cancer diagnosis because concerns about biological conception are a source of anxiety and can even affect the patient's cancer recovery. The aim of this study was to evaluate oncology patients' feelings, concerns, and life quality impacts related to FP. METHODS: This qualitative cross-sectional study was based on a questionnaire administered to a selected group of women diagnosed with cancer who underwent FP. Thirty-four eligible women (23-39 years old) completed this questionnaire. RESULTS: Two of the participants already had a child, and most of them (61.8%) stated a desire to have children at the time of FP. Their feelings primarily involved safety (44.1%) and hope (23.5%). Time and/or financial issues (82.4%) were the main challenge for FP. All of the women noted the importance of FP, with many stating that it is warranted to allow the possibility of a biological pregnancy due to the risk of infertility. Finally, questions about the impact on their lives if they had not undergone FP indicated emotional impairment, low quality of life, relationship problems, and uncertainty about maternity. CONCLUSIONS: FP for oncology patients is a positive strategy. The women in this study felt that FP was a worthwhile process and that the security of having undergone FP brought them peace during oncological treatment and contributed to their quality of life.

RESUMEN

Pelvic floor dysfunction (PFD) is a common condition that typically affects women older than 50 years and decreases the quality of life. Weakening of support structures can involve all three pelvic compartments and cause a combination of symptoms, including constipation, urinary and fecal incontinence, obstructed defecation, pelvic pain, perineal bulging, and sexual dysfunction. The causes of PFD are complex and multifactorial; however, vaginal delivery is considered a major predisposing factor. Physical examination alone is limited in the evaluation of PFD; it frequently leads to an underestimation of the involved compartments. Imaging has an important role in the clinical evaluation, yielding invaluable information for patient counseling and surgical planning. Three- and four-dimensional translabial ultrasonography (US) is a relatively new imaging modality with high accuracy in the evaluation of PFD such as urinary incontinence, pelvic organ prolapse, and puborectalis avulsion. Evaluation of mesh implants is another important indication for this modality. Dynamic magnetic resonance (MR) imaging of the pelvic floor is a well-established modality for pelvic floor evaluation, with high-resolution images yielding detailed anatomic information and dynamic sequences yielding functional data. Specific protocols and dedicated image interpretation are required with both of these imaging methods. In this article, the authors review the normal anatomy of the female pelvic floor by using a practical approach, discuss the roles of translabial US and MR imaging in the investigation of PFD, describe the most appropriate imaging protocols, and illustrate the most common imaging findings of PFD in the anterior, middle, and posterior compartments of the pelvis. Online supplemental material is available for this article. ©RSNA, 2018.
