RESUMEN

STUDY QUESTION: Is oocyte developmental competence associated with changes in granulosa cell (GC) metabolism? SUMMARY ANSWER: GC metabolism is regulated by the LH surge, altered by obesity and reproductive aging, and, in women, specific metabolic profiles are associated with failed fertilization versus increased blastocyst development. WHAT IS KNOWN ALREADY: The cellular environment in which an oocyte matures is critical to its future developmental competence. Metabolism is emerging as a potentially important factor; however, relative energy production profiles between GCs and cumulus cells and their use of differential substrates under normal in vivo ovulatory conditions are not well understood. STUDY DESIGN, SIZE, DURATION: This study identified metabolic and substrate utilization profiles within ovarian cells in response to the LH surge, using mouse models and GCs of women undergoing gonadotropin-induced oocyte aspiration followed by IVF/ICSI. PARTICIPANTS/MATERIALS, SETTING, METHODS: To comprehensively assess follicular energy metabolism, we used real-time metabolic analysis (Seahorse XFe96) to map energy metabolism dynamics (mitochondrial respiration, glycolysis, and fatty acid oxidation) in mouse GCs and cumulus-oocyte complexes (COCs) across a detailed time course in the lead up to ovulation. In parallel, the metabolic profile of GCs was measured in a cohort of 85 women undergoing IVF/ICSI (n = 21 with normal ovarian function; n = 64 with ovarian infertility) and correlated with clinical parameters and cycle outcomes. MAIN RESULTS AND THE ROLE OF CHANCE: Our study reveals dynamic changes in GC energy metabolism in response to ovulatory LH, with mitochondrial respiration and glycolysis differentially affected by obesity versus aging, in both mice and women. High respiration in GCs is associated with failed fertilization (P < 0.05) in a subset of women, while glycolytic reserve and mitochondrial ATP production are correlated with on-time development at Day 3 (P < 0.05) and blastocyst formation (P < 0.01) respectively. These data provide new insights into the cellular mechanisms of infertility, by uncovering significant associations between metabolism within the ovarian follicle and oocyte developmental competence. LIMITATIONS, REASONS FOR CAUTION: A larger prospective study is needed before the metabolic markers that were positively and negatively associated with oocyte quality can be used clinically to predict embryo outcomes. WIDER IMPLICATIONS OF THE FINDINGS: This study offers new insights into the importance of GC metabolism for subsequent embryonic development and highlights the potential for therapeutic strategies focused on optimizing mitochondrial metabolism to support embryonic development.

RESUMEN

Recently, more than 200 live births following ovarian tissue cryopreservation (OTC) and transplantation in cancer survivors have been reported worldwide. However, cancer survivors with minimal residual disease (MRD) in cryopreserved ovarian tissue are at the risk of relapse through the graft. Here, we report a rare case of a 19-year-old female patient with non-Hodgkin lymphoma who had MRD in the ovary harvested for OTC. The patient was diagnosed with aggressive B-cell lymphoma after gingival biopsy. The 18F-fluoro-2-deoxy-D-glucose positron emission tomography scan performed before OTC showed no viable lesions in either ovary. However, on histological evaluation, we detected infiltration of lymphoma cells in the ovary. Informed consent about MRD is required even if there is no evidence of MRD in the ovary before OTC. Patients whose cryopreserved ovaries have MRD may require the development of alternative assisted reproductive technologies such as in vitro growth or artificial ovary.

RESUMEN

Multimodal treatment, including assisted reproductive technology, is necessary in young patients with advanced borderline ovarian tumors. However, the details of long-term follow-up cases have not been reported. In this report, a 19-year-old patient presented with a stage IIIC serous borderline tumor. The patient underwent five fertility-sparing surgeries. The tumor did not respond to any of the three lines of chemotherapy administered. Serological and radiological responses were observed following hormonal treatment with leuprorelin, followed by a fourth surgery. Before the planned fifth surgery for complete resection of both adnexa, cryopreservation of the fertilized eggs was performed. At age 36, when the disease-free interval exceeded the previous one, we proposed embryo transfer; however, she declined fertility treatment. The patient had developed rheumatoid arthritis and childbirth not a priority. The patient had lived without any evidence of disease for 7 years following the last surgery and 20 years after the initial visit.

RESUMEN

AIM: This study aimed to clarify the impact of coronavirus disease 2019 on gynecology practice in Japan, in particular, on surgeries for benign gynecological diseases. METHODS: An online questionnaire was distributed to 966 facilities in Japan, including core facilities, facilities participating in perinatal and gynecologic oncology registries, and facilities certified for training by the Japanese Society of Obstetrics and Gynecology Endoscopy. The number of surgeries performed was compared between 2019 and 2020, when the novel coronavirus disease was prevalent. RESULTS: Five hundred and eighty (58.2%) facilities responded. The total number of surgeries decreased from 129 648 in 2019 to 118 565 in 2020, by 8.5%, for all surgical procedures. However, there was a clear increase in the number of robotic surgeries performed in 2020 compared to that in 2019 for all populations. The number of total hysterectomies decreased markedly from 15 385 in 2019 to 12 531 in 2020, a fall of 10.1%. CONCLUSIONS: The number of surgeries for benign gynecological diseases decreased by 8.5% in 2020 compared to that in 2019. This value is among the lowest in the world.

RESUMEN

AIM: Ovarian tissue cryopreservation (OTC) is performed for fertility preservation in cancer patients undergoing chemotherapy. Although anti-Müllerian hormone is used as a marker for ovarian reserve, serum levels do not always correlate with the number of follicles. Additionally, the follicle development stage most affected by chemotherapy is unclear. We examined the association between serum anti-Müllerian hormone levels and the number of remaining primordial follicles after chemotherapy, as well as which follicle stage is most affected by chemotherapy before ovarian cryopreservation. METHODS: Thirty-three patients who underwent OTC were divided into the chemotherapy (n = 22) and non-chemotherapy (n = 11) groups; their ovarian tissues underwent histological examination. Pathological ovarian damage induced by chemotherapy was assessed. Ovarian volumes were estimated from weights. We compared the number of follicles at each developmental stage as a percentage of primordial follicles between the groups. The relationship between serum anti-Müllerian hormone level and primordial follicle density was analyzed. RESULTS: The chemotherapy group had a significantly lower serum anti-Müllerian hormone level, ovarian volume, and density of developing follicles than the non-chemotherapy group. Serum anti-Müllerian hormone levels correlated with primordial follicle density only in the non-chemotherapy group. The chemotherapy group had significantly lower numbers of primary and secondary follicles. CONCLUSIONS: Chemotherapy induces ovarian damage and follicle loss. However, serum anti-Müllerian hormone level does not always reflect the number of primordial follicles after chemotherapy, and chemotherapy more significantly affects primary and secondary follicles than primordial follicles. Many primordial follicles remain in the ovary after chemotherapy, supporting OTC for fertility preservation.

RESUMEN

BACKGROUND: This study aimed to analyze the physical and psychosocial development of long-term survivors (age >1 year) of thanatophoric dysplasia (TD). METHODS: The participants were 20 long-term survivors recruited from a cohort obtained through a nationwide survey for TD conducted across 147 pediatric departments in Japan between 2012 and 2016. Their guardians consented to participate in this study. Medical and psychosocial information was collected through questionnaires and interviews with primary physicians and guardians. RESULTS: The participants were 1.2-27.8 years old, and all showed marked growth deficiency. The mean length at birth was 36 cm (-3.4 SD to -7.9 SD). The adult height (age >16 years) was <-15.2 SD. All individuals showed severely delayed psychomotor development. The highest level of psychosocial development was equivalent to that at 2 years of age. Skin disorders (acanthosis nigricans and seborrheic keratoses) were common. Eleven subjects had been hospitalized or institutionalized consistently after birth, and nine had been moved to home care, and four were exclusively orally fed. All individuals required assisted ventilation. CONCLUSIONS: Long-term survival of TD individuals is common. Some individuals enjoy home-based lives; however, they are severely psychosocially and physically disabled and require meticulous respiratory and nutritional support.

RESUMEN

BACKGROUND: Epidural analgesia relives pain during labor. However, the long-term effects on neurodevelopment in children remain unclear. We explored associations between exposure to epidural analgesia during labor and childhood neurodevelopment during the first 3 years of life, in the Japan Environment and Children's Study (JECS), a large-scale birth cohort study. METHODS: Pregnant women were recruited between January 2011 and March 2014, and 100,304 live births of singleton children born at full-term by vaginal delivery, and without congenital diseases were analyzed. Data on mothers and children were collected using a self-administered questionnaires and medical record transcripts. The children's neurodevelopment was repeatedly assessed for five domains (communication, gross motor, fine motor, problem solving, and personal-social), using the Ages and Stages Questionnaires, Third Edition, at six time points from age 6 to 36 months. After adjusting for potential confounders, the associations between exposure to epidural analgesia during labor and children's neurodevelopment at each time point were assessed. RESULTS: Of the 42,172 children with valid data at all six time points, 938 (2.4%) were born to mothers who received epidural analgesia during labor. Maternal exposure to epidural analgesia was associated with neurodevelopmental delays during the first 3 years after birth. Delay risks in gross and fine motor domains were the greatest at 18 months (adjusted odds ratio (aOR) [95% confidence interval (CI)]: 1.40 [1.06, 1.84] and 1.54 [1.17, 2.03], respectively), subsequently decreasing. Delay risks in communication and problem-solving domains were significantly high at 6 and 24 months, and remained significant at 36 months (aOR [95% CI]: 1.40 [1.04, 1.90] and 1.28 [1.01, 1.61], respectively). Exposure to epidural analgesia was also associated with the incidence of problem solving and personal-social delays from 18 to 24 months old. Neurodevelopmental delay risks, except for communication, were dominant in children born to mothers aged ≥30 years at delivery. CONCLUSIONS: This study showed that maternal exposure to epidural analgesia during labor was associated with neurodevelopmental delays in children during the first 3 years after birth.

RESUMEN

Background: Some diseases have sex differences. There have been no reports on the relationship between anti-sperm antibodies (ASA) and sex differences. Methods: ASA are detected by sperm-immobilization test using patients' sera in women. In men, the ASA testing is generally performed by direct-immunobead test. Main findings: Sperm-immobilizing antibodies in women inhibit sperm migration in their genital tract and exert inhibitory effects on fertilization. ASA bound to sperm surface in men also show inhibitory effect on sperm passage through cervical mucus. The fertilization rate of IVF significantly decreased when sperm were coated with higher numbers of ASA. For women with the antibodies, it is important to assess individual patients' SI50 titers. In patients with continuously high SI50 titers, pregnancy can be obtained only by IVF. For men with abnormal fertilizing ability by ASA, it is necessary to select intracytoplasmic sperm injection. Production of sperm-immobilizing antibodies is likely to occur in women with particular HLA after exposure to sperm. The risk factors for ASA production in men are still controversial. Conclusion: Attention to sex differences in specimens, test methods and the diagnosis of ASA should be paid. For patients with ASA, treatment strategies have been established by considering sex difference for each.

RESUMEN

Purpose: NKp46, a receptor on NK cells, is involved in cytotoxicity and cytokine production. The authors aimed to evaluate the effect of NKp46 on decidual NK (dNK) cells during pregnancy and whether it can be a marker for immunological abnormalities in women with recurrent pregnancy loss (RPL). Methods: Flow-cytometric analysis was made to assess NKp46 expression and intracellular cytokine production of dNK cells. The proportion of NKp46+ dNK cells was analyzed among RPL patients who aborted karyotypically normal pregnancies and those who either aborted karyotypically abnormal pregnancies or without genetic studies, and controls who were going through the induced abortion. Results: The %NKp46+ and %NKp46bright dNK cells were significantly lower in the RPL women who aborted karyotypically normal pregnancies than in the control group. The %NKp46bright dNK cells were significantly correlated with the NK1/NK2 ratio of dNK cells. The %NKp46+ dNK cell cutoff for RPL with immunological abnormalities was determined by the ROC curve analysis. In women with the low %NKp46+ dNK, NK1/NK2 ratios were significantly higher than those with the high. Conclusion: RPL patients with an immunological abnormality have decreased NKp46 expression and NK1 shift in dNK cells. NKp46 expression could be a marker for RPL of immunological abnormalities.

RESUMEN

Purpose: Our aim is to make an ideal embryo culture medium close to human oviduct fluid (HOF) components, and to evaluate the quality of this medium with embryo quality and clinical outcomes in assisted reproductive technology (ART) by a prospective randomized controlled trial (RCT). Methods: Study I: HOF was collected laparoscopically from patients (n = 28) with normal pelvic findings. According to HOF analysis results, the new medium "HiGROW OVIT®" (OVIT) was designed. Study II: Embryos (2 pronuclei (2PN) = 9633) were assigned from 1435 patients. The blastulation rate (BR), good BR (gBR), utilized (transferred/cryo-preserved) BR (uBR), pregnancy rate (PR), and miscarriage rate (MR) were compared between the OVIT and control groups by RCT. Results: The novel medium 'OVIT' was produced according to 31 HOF components. The concentrations of essential amino acids (e-AAs) were lower in OVIT than in current media, yet the opposite was true for ne-AA concentrations. gBR and uBR were higher in the OVIT group than in the control group. In the older female group, gBT and uBR were significantly higher in the OVIT group. Conclusions: The novel medium 'OVIT' was produced according to HOF data. The OVIT had significantly better embryo quality and clinical outcomes than the current media.

RESUMEN

AIM: Patients with major depression present with an increased serum insulin-like growth factor-1 (IGF-1) concentration. However, the longitudinal relationship between serum IGF-1 levels and depression development remains unclear. This study aimed to investigate the longitudinal association between the serum IGF-1 concentration in the first trimester of pregnancy and postpartum depression development using data obtained from the Japan Environment and Children's Study (JECS). METHODS: The JECS included 97 415 pregnant women; among them, 8791 were enrolled in this study. Data regarding depression in the first trimester, postpartum depression development at 1 month after childbirth, and other covariates were collected using a self-administered questionnaire. Serum IGF-1 levels were measured in the first trimester of pregnancy. The participants were divided into four groups according to the serum IGF-1 level. RESULTS: In the first trimester, serum IGF-1 levels were not significantly associated with psychological distress in pregnant women. In the longitudinal analyses, however, postpartum depression development in mothers within the highest quartile for serum IGF-1 concentration in the first trimester was significantly less common than in those within the lowest quartile (odds ratio 0.48, 95% confidence interval 0.30-0.79). CONCLUSION: Pregnant women with a high serum IGF-1 concentration in the first trimester were less likely to develop postpartum depression than those with a low concentration. A high serum IGF-1 concentration during pregnancy may help to protect against postpartum depression development.

RESUMEN

PURPOSE: Laevo (l)-carnitine plays important roles in reducing the cytotoxic effects of free fatty acids by forming acyl-carnitine and promoting beta-oxidation, leading to alleviation of cell damage. Recently, the mitochondrial functions in morula has been shown to decrease with the maternal age. Here, we assessed the effect of l-carnitine on mitochondrial function in human embryos and embryo development. METHODS: To examine the effect of L-carnitine on mitochondrial function in morulae, 38 vitrified-thawed embryos at the 6-11-cell stage on day 3 after ICSI were donated from 19 couples. Each couple donated two embryos. Two siblings from each couple were divided randomly into two groups and were cultured in medium with or without 1 mM L-carnitine. The oxygen consumption rates (OCRs) were measured at morula stage. The development of 1029 zygotes cultured in medium with or without L-carnitine was prospectively analyzed. RESULTS: Addition of L-carnitine to the culture medium significantly increased the OCRs of morulae and improved the morphologically-good blastocyst formation rate per zygote compared with sibling embryos. Twenty healthy babies were born from embryos cultured in L-carnitine-supplemented medium after single embryo transfers. CONCLUSION(S): L-carnitine is a promising culture medium supplement that might be able to counteract the decreased mitochondrial function in human morula stage embryos.

RESUMEN

PURPOSE: In a previous study, a new method was described using the sperm immobilization test (SIT) with computer-aided sperm analysis (CASA). However, obtaining high-quality sperm as needed was a known issue. Here, we compared the results of using frozen-thawed sperm and fresh sperm for the SIT using the CASA method. METHODS: For the frozen-thawed preparation, 500 µL of condensed semen and 500 µL of Sperm Freeze were mixed in a cryovial and cryopreserved in liquid nitrogen. Density gradient centrifugation was used for the collection of motile sperm in both the fresh and frozen-thawed sperm preparations. A total of 50 serum samples were prepared for both the fresh and frozen-thawed sperm with each sample tested containing 10 µL of serum, 1 µL of either fresh or frozen motile sperm suspension, and 2 µL of complement. Sperm motilities were measured using CASA after a 1-hour incubation period for both fresh and frozen-thawed sperm. RESULTS: Both fresh and frozen-thawed sperm reacted similarly when exposed to serum containing sperm-immobilizing antibodies asserting the use of frozen-thawed sperm for the diagnosis of immunological infertility. CONCLUSION: These results suggest the possibility of using cryopreserved sperm for the SIT when fresh sperm is unavailable.

RESUMEN

PURPOSE: The fertility of women decreases with age because of factors such as an increased incidence of aneuploidies and-possibly-decreased mitochondrial activity in oocytes. However, the relationship between maternal aging and mitochondrial function of their embryos remains unknown. Here, we assessed the relationship between maternal age and mitochondrial functions in their oocytes and embryos METHODS: The relationships between maternal age and oxygen consumption rates (OCRs), mitochondrial DNA (mtDNA) copy numbers, or blastocyst development was investigated using 81 embryos donated from 63 infertility couples. The developmental rates from morulae to blastocysts were retrospectively analyzed using data of 105 patients. RESULTS: The OCRs of morulae decreased with maternal age (r2 = 0.48, P < 0.05) although there were no relationships between maternal age and mtDNA copy number in any stages. The more oxygen consumed at the morula stage, the shorter time was required for embryo development to the mid-stage blastocyst (r2 = 0.236, P < 0.05). According to the clinical data analysis, the developmental rate from morulae to blastocysts decreased with maternal age (P < 0.05, < 37 years, 81.1%, vs. ≥ 37 years, 64.1%). CONCLUSIONS: The data of the present study revealed that mitochondrial function at the morula stage of human embryos decreased with their maternal age and a decrease of mitochondrial function led to slow-paced development and impaired developmental rate from morulae to blastocysts.

RESUMEN

In this study, we examined the effects of 5-hydroxytryptamine (5-HT) on the motility and hyperactivation of mouse spermatozoa. In addition, we examined whether 5-HT increases the success of in vitro fertilization (IVF) in mice. Interestingly, 5-HT and agonists of the 5-HT2, 5-HT3, 5-HT4, and 5-HT7 receptors significantly increased the percentage of hyperactivated spermatozoa but did not affect the percentage of motile spermatozoa. Moreover, agonists of the 5-HT2, 5-HT3, and 5-HT4 receptors significantly affected the velocities, linearity, straightness, wobbler coefficient, amplitude and/or frequency of spermatozoa. In particular, the improvement of hyperactivation by 5-HT was strongly inhibited by antagonists of the receptors 5-HT4 and 5-HT7 and was completely inhibited by a mixture of the four 5-HT-receptor antagonists. The increase in hyperactivation by the agonists was significantly inhibited by the corresponding 5-HT-receptor antagonist. Moreover, 5-HT significantly increased the percentage of two-cell embryos. The increase in the IVF success rate by 5-HT was significantly inhibited by a 5-HT4-receptor antagonist. These results suggest that 5-HT increased hyperactivation through the 5-HT receptors and increased the success of IVF in mice.

RESUMEN

AIM: To investigate the effects of leuprorelin using a self-administered quality-of-life (QOL) questionnaire in patients with recurrent gynecological cancer. METHODS: Records of patients who received 3.75 mg leuprorelin every 4 weeks for the treatment of recurrent gynecological cancer were retrospectively reviewed. The physical domain of the QOL questionnaire, Care Notebook, was used to assess physical symptoms. Symptom deterioration was defined as a ≥10-point increase in baseline score; otherwise, symptoms were defined as controlled. Radiological and serological responses were evaluated according to the 2011 Gynecological Cancer Intergroup criteria. RESULTS: From 2007 to 2015, 25 patients were administered leuprorelin for the treatment of epithelial ovarian cancer, granulosa cell tumor, endometrial cancer, endometrial stromal sarcoma and clear cell cervical cancer (in 13, 3, 6, 2 and 1 patients, respectively). Twenty patients had received a median of three lines (range 1-12 lines) of chemotherapy. Ten patients had progressive disease during their previous round of chemotherapy. Twenty patients completed the questionnaire every 4 weeks. Following leuprorelin treatment for 8 weeks, the symptom and disease control rates were 65% (13/20) and 44% (11/25), respectively. Two patients, one each with granulosa cell tumor and endometrial cancer, had stable disease at 6 months. Among the 20 patients who completed the QOL questionnaire, symptom control and disease control at 8 weeks showed a significant correlation (P = 0.016). CONCLUSION: Leuprorelin had minimal anticancer activity. The physical domain of the QOL questionnaire could be used to assess effects of hormonal treatment.

RESUMEN

Resuscitative hysterotomy (RH) is a resuscitation technique, allowing the restoration of a pregnant patient's heartbeat. Here, we reported a case of RH performed in a patient with cardiac arrest as a complication of a peripartum cardiomyopathy. A 29-year-old woman with suspected hemolysis, elevated liver enzymes, low platelet syndrome was admitted to the hospital. Cardiopulmonary resuscitation and RH were initiated at 30 weeks of gestation. The infant was successfully delivered 2 min after the mother's cardiac arrest, weighting 1388 g. At the first minute, the Apgar score was 3 and the 5th minute was 6. After delivery, defibrillation was performed on the mother and restoration of spontaneous circulation was observed. However, she was hemodynamically unstable and approximately 2 months later she died. After cardiac arrest, it is possible that RH could improve the hemodynamic status. The opportunity of performing a RH is rare; however, it is necessary to be familiarized with the technique as a resuscitation method.

RESUMEN

The high toxicity of chemotherapy can damage a patient's gonadal function, leading to premature ovarian insufficiency (POI). Here, we report the case of a patient suffering from POI after chemotherapy for breast cancer, who 3 years later ovulated spontaneously and became pregnant. The patient, a 31-year-old infertile women, nulligravida, was diagnosed with breast cancer. The Anti-Müllerian Hormone (AMH) level in her serum was 1.85 ng/mL before multimodal treatment for cancer. She later visited our hospital for amenorrhea and 2 years after cancer treatment, she was diagnosed with POI. Her AMH level at that point was less than 0.1 ng/mL. One year after the diagnosis of POI, the patient's AMH level increased slightly to 0.14 ng/mL and she ovulated spontaneously. The patient later became pregnant using Assisted Reproductive Technology on the fourth attempt.During the course of treatment for infertility at our hospital, the AMH levels in her serum changed along with the recovery of ovarian function. These findings suggest the possibility that ovulation and pregnancy could be predicted by the chronological changes of the AMH levels in the patient's serum.

RESUMEN

This paper presents the case of an 84-year-old man who was referred to the clinic because of decreased appetite and weight loss. He was diagnosed with anemia and white blood cell count reduction by a local doctor. In consideration of blood diseases, he was referred to the hospital to the department of hematology, and laboratory tests revealed a white blood cell count of 4,400/mL, hemoglobin level of 8.0 g/dL, platelet count of 12,800/mL, and high PSA level of 12.895 ng/mL. Cancer cells were found in the bone marrow biopsy and tested negative on PSA immunostaining. PET-CT revealed increased accumulation of FDG in the whole bone marrow. A biopsy of the prostate showed poorly differentiated adenocarcinoma with a Gleason score of 5+5=10 and weakly positive PSA immunostaining. Prostate cancer with carcinomatosis of the bone marrow was diagnosed. He underwent bicalutamide and degarelix treatment. He was alive 12 months after his first visit.

RESUMEN

PURPOSE: Sperm cryopreservation is the gold standard for maintaining fertility in male survivors of cancer. In order to help increase the future success of fertility preservation in these patients, the present state of sperm cryopreservation was examined at the current institution and its challenges were discussed. METHODS: Between January, 2004 and February, 2017, 31 male patients with cancer were introduced to the center for fertility preservation. The ages and semen characteristics of these patients were examined and compared between those whose sperm were cryopreserved before (the pretreatment group) and after (the post-treatment group) cancer treatment. RESULTS: The mean sperm concentration of the pretreatment group was significantly higher than that of the post-treatment group. Normozoospermia was found in eight and three patients in the pretreatment and the post-treatment groups, respectively, albeit this difference was not significant. In contrast, the prevalence of azoospermia was higher in the post-treatment group (five patients) than in the pretreatment group (one patient). CONCLUSION: As many patients possibly suffer from infertility following chemotherapy, it is necessary to provide fertility preservation opportunities to young male patients with cancer prior to the commencement of cancer treatment.
