RESUMO
First trimester pregnancy losses are commonly attributed to chromosomal abnormalities. The causes of pregnancy loss following transfer of a euploid embryo are not fully elucidated. The aim of this study was to evaluate clinical and embryological parameters for pregnancy failure following the transfer of a single euploid embryo. Pregnancy outcomes of single euploid embryo transfers from a single centre between January 2017 and March 2020 were retrospectively evaluated. Several clinical and embryological parameters were evaluated in consideration to pregnancy outcomes; total pregnancy loss and live birth. Endometrial preparation type, number of previous frozen embryo transfer cycles, history of recurrent pregnancy loss, higher body mass index, presence of endometriosis and/or adenomyosis and embryo quality were found to be significantly different between two groups. Morphokinetic parameter analysis of 523 euploid embryos using time-lapse imaging did not show any statistical differences between the two groups, however a significantly higher rate of uneven blastomeres in the cleavage stage was observed in the total preganncy loss group. Evaluation of clinical and embryological data can reveal possible factors associated with pregnancy loss that can facilitate improved patient consultation. Feasible interventions can potentially increase the chance of achieving a live birth.
RESUMO
PURPOSE: Can the risk factors that cause first trimester pregnancy loss in good-quality frozen-thawed embryo transfer (FET) cycles be predicted using machine learning algorithms? METHODS: This is a retrospective cohort study conducted at Sisli Memorial Hospital, ART and Reproductive Genetics Center, between January 2011 and May 2021. A total of 3805 good-quality FET cycles were included in the study. First trimester pregnancy loss rates were evaluated according to female age, paternal age, body mass index (BMI), diagnosis of infertility, endometrial preparation protocols (natural/artificial), embryo quality (top/good), presence of polycystic ovarian syndrome (PCOS), history of recurrent pregnancy loss (RPL), recurrent implantation failure (RIF), severe male infertility, adenomyosis and endometriosis. RESULTS: The first trimester pregnancy loss rate was 18.2% (693/ 3805). The presence of RPL increased first trimester pregnancy loss (OR = 7.729, 95%CI = 5.908-10.142, P = 0.000). BMI, which is > 30, increased first trimester pregnancy loss compared to < 25 (OR = 1.418, 95%CI = 1.025-1.950, P = 0.033). Endometrial preparation with artificial cycle increased first trimester pregnancy loss compared to natural cycle (OR = 2.101, 95%CI = 1.630-2.723, P = 0.000). Female age, which is 35-37, increased first trimester pregnancy loss compared to < 30 (OR = 1.617, 95%CI = 1.120-2.316, P = 0.018), and female age, which is > 37, increased first trimester pregnancy loss compared to < 30 (OR = 2.286, 95%CI = 1.146-4,38, P = 0.016). The presence of PCOS increased first trimester pregnancy loss (OR = 1.693, 95%CI = 1.198-2.390, P = 0.002). The number of previous IVF cycles, which is > 3, increased first trimester pregnancy loss compared to < 3 (OR = 2.182, 95%CI = 1.708-2.790, P = 0.000). CONCLUSIONS: History of RPL, RIF, advanced female age, presence of PCOS, and high BMI (> 30 kg/m2) were the factors that increased first trimester pregnancy loss.

RESEARCH QUESTION: Can a methodology be developed for case selection and whole-exome sequencing (WES) analysis of women who are infertile owing to recurrent oocyte maturation defects (OOMD) and/or preimplantation embryo lethality (PREMBL)? DESIGN: Data were collected from IVF patients attending the Istanbul Memorial Hospital (2015-2021). A statistical methodology to identify infertile endophenotypes (recurrent low oocyte maturation rate, low fertilization rate and preimplantation developmental arrest) was developed using a large IVF dataset (11,221 couples). Twenty-eight infertile women with OOMD/PREMBL were subsequently enrolled for WES on their genomic DNA. Pathogenic variants were prioritized using a custom-made bioinformatic pipeline set to minimize false-positive discoveries through resampling in control cohorts (the Human Genome Diversity Project and 1343 whole-exome sequences from oocyte donors). Individual single-cell RNA sequencing data from 18 human metaphase II (MII) oocytes and antral granulosa cells was used for genome-wide validation. WES and bioinformatics were performed at Igenomix and the National Research Council, Italy. RESULTS: Variant prioritization analysis identified 265 unique variants in 248 genes (average 22.4 per sample). Of the genes harbouring high-impact variants 78% were expressed by MII oocytes and/or antral granulosa cells, significantly higher than for random sample of controls (odds ratioâ¯=â¯5, Fisher's exact Pâ¯=â¯0.0004). Seven of the 28 women (25%) were homozygous carriers of missense pathogenic variants in known candidate genes for OOMD/PREMBL, including PATL2, NLRP5 (nâ¯=â¯2),TLE6, PADI6, TUBB8 and TRIP13. Furthermore, novel gene-disease associations were identified. In fact, one woman with a low oocyte maturation rate was a homozygous carrier of high-impact variants in ENSA, an essential gene for prophase I meiotic transition in mice. CONCLUSIONS: This analytical framework could reveal known and new genes associated with isolated recurrent OOMD/PREMBL, providing essential indications for scaling this strategy to larger studies.

INTRODUCTION AND HYPOTHESIS: To assess the critical threshold to optimize operating room (OR) time for each surgical team member in robotically assisted sacrocolpopexy (RASCP) and to evaluate the most efficient team compositions. METHODS: All women who underwent RASCP for pelvic organ prolapse (POP) were prospectively entered in a database. Patients having unrelated concomitant surgery were excluded. Our primary outcome measure was total OR time. We utilized factor analysis, regression analysis, and analysis of variance, OR time mapping, and stochastic optimization to identify 'optimal' surgical team configuration. RESULTS: The database included 359 consecutive RASCPs, all performed for stage III-IV POP: 156 (43%) were with total and 44 (12%) supracervical hysterectomies and 159 (44%) post-hysterectomy. Mean age was 58.6 ± 9.3 years. Mean parity was 2.8 ± 1.4, and mean body mass index was 28 ± 4.7 kg/m2. A total of 4 surgeons, 34 first assistants, 20 circulating nurses, 15 surgical technologists, and 59 anesthesiologist/nurse anesthetists were involved. Optimal experience levels for each team member were achieved at the following number of robotic procedures: surgeon 44; first assistant 13; surgical technologist 66; circulating nurse 56; anesthesia provider 46. Our analysis revealed that the surgical technologist and first assistant played the most significant roles within the team. The surgeon was ranked third followed by the circulating nurse and anesthesia provider, respectively. CONCLUSION: Operating time in robotic surgery is multifactorial. Experience of each member of a robotic surgery team is critical. An optimal team can be composed of a variety of combinations of experience levels among the robotic team members.

OBJECTIVE: To investigate the efficacy of oral dydrogesterone for luteal phase support (LPS) in modified natural cycle frozen-thawed embryo transfers (mNC-FET) compared to micronized vaginal progesterone (MVP) gel. METHODS: This was a randomized, single-center, parallel controlled trial conducted at an ART and Reproductive Genetics Centre within a private hospital between January and August 2019. A total of 134 women, aged below 38, were assigned randomly to receive oral dydrogesterone (n=67) or MVP (n=67) for LPS in mNC-FET. The primary outcome was ongoing pregnancy rate (OPR) and secondary outcomes were clinical pregnancy and miscarriage rates, patients' satisfaction and tolerability of oral and vaginal progesterone. A questionnaire was developed to compare patient satisfaction and side effect profiles. RESULTS: There was no significant difference in demographic features such as female age, body mass index, AMH levels and fresh cycle characteristics between two groups (p>0.05). When mNC-FET outcomes were compared, OPR was 68.7 % in MVP gel group and 71.6 % in the dydrogesterone group respectively percentage difference, -2.99; 95 % CI: -17.96, 13.10) Biochemical and clinical pregnancy rates and biochemical and clinical miscarriage rates were also similar between two groups. A significantly higher patient tolerability score was present in the dydrogesterone arm (4.09 ± 0.96 vs 3.36 ± 1.23, p=0.001). CONCLUSION: Our results suggest that oral dydrogesterone provides similar ongoing pregnancy rates compared to MVP gel as a LPS in mNC FET. Since dydrogesterone is an effective and easy-to-use option with fewer intolerable side effects including vaginal irritation, vaginal discharge, and preventing sexual intercourse, it can be used as LPS in mNC FET.

Mosaic embryos have the potential to implant and develop into healthy babies. The transfer of mosaic embryos is now considered to be a possible option for women undergoing ART with preimplantation genetic testing for aneuploidies and in the absence of euploid embryos, particularly those with diminished ovarian reserve and/or advanced maternal age. It can aid in avoiding the discard of potentially viable embryos, which might otherwise result in healthy babies. In over 500 studies on mosaicism, there have been no reports of mosaicism in babies born following the transfer of mosaic embryos. Here, we present a case report of a 39-year-old woman with diminished ovarian reserve with only one blastocyst available for trophectoderm biopsy. The transfer of the embryo, which showed 35% mosaicism of monosomy 2, resulted in pregnancy. Amniocentesis revealed a mosaic trisomic mos46,XX(98)/47,XX,+2(2) karyotype. There were no pathological findings in detailed ultrasonography, and the fetus showed a normal fetal growth with no evidence of intrauterine growth retardation. A healthy female baby was born at Week 37. The peripheral blood chromosome analysis validated with fluorescence in situ hybridization showed 2% mosaic monosomy 2 [mos45,XX,-2(2)/46,XX(98)]. This is the first reported case of true fetal mosaicism resulting in a live birth following the transfer of a known mosaic embryo. Worldwide, prenatal diagnosis has shown the depletion of mosaicism in embryos transferred after they have been reported as mosaics. Our case demonstrates the need for close prenatal monitoring and diagnosis by early amniocentesis, preferably at >14 weeks gestation.

AIM: To evaluate maternal and cord blood irisin levels in pregnant women with gestational diabetes mellitus (GDM) and in obese pregnant women without GDM. METHODS: The study included 109 patients, with 34 patients in the GDM group, 40 in the obese non-GDM group, and 35 in the control group. Maternal serum irisin levels at the time of delivery were measured by an enzyme-linked immunosorbent assay kit. The correlation of serum irisin levels with metabolic parameters and anthropometric measurements was analyzed. RESULTS: There were significant differences between the study groups in terms of cord arterial, cord venous, and maternal serum irisin levels (P < 0.001, P < 0.01, P < 0.001, respectively). Cord arterial, cord venous, and maternal serum irisin levels were higher in the obese group compared to the control (P < 0.01, P < 0.01, P < 0.01, respectively) and the GDM group (P < 0.001, P < 0.001, P < 0.001, respectively). CONCLUSION: Elevation in irisin levels of women who have pregnancies complicated with obesity may be explained as part of the compensation mechanism against disturbed metabolic functions. Pregnant individuals with GDM have lower serum irisin levels in comparison to healthy pregnant women. In this regard, it is possible that the measurement of serum irisin levels may be utilized in the future for prediction, prevention, and treatment of GDM.

OBJECTIVES: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. It can affect various organ systems, and respiratory mucosa has been reported as being hormone responsive. STUDY DESIGN: A case-control study consisting of 50 women with PCOS and 30 control subjects matched for age and body mass index was conducted, in order to investigate nasal mucociliary clearance time (NMCT) in patients with PCOS. Serum basal hormonal-biochemical parameters and NMCT were evaluated on menstrual cycle days 2-5 for all participants. RESULTS: The mean NMCT in PCOS and control groups was 10.45±2.88 and 6.92±1.78, respectively (p=0.0001). A significant positive correlation was found between NMCT and duration of disease (r=0.52; p=0.001), serum total testosterone level (r=0.28; p=0.04), and luteinizing hormone/follicle stimulating hormone (r=0.29; p=0.04). CONCLUSIONS: Our findings indicate that PCOS is associated with altered NMCT. Prolonged NMCT predisposes patients to respiratory tract and middle ear infections, and clinicians should be aware of this.

OBJECTIVE: Immediate skin-to-skin contact (ISSC) and early breastfeeding are recommended for the wellbeing of the neonate. In this study, we aimed to evaluate the effect of ISSC and early breastfeeding on maternal oxidative stress and postoperative pain. METHODS: A total of 90 patients were randomized into two groups based on the timing of skin-to-skin contact and breastfeeding. Group 1 (n = 45) was provided ISSC and breastfeeding in the operating room during the cesarean section (C/S). Group 2 (n = 45) breastfed their babies 1 h after the C/S. As markers of oxidative stress, maternal serum levels of total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress indices (OSI) were evaluated. Maternal oxytocin levels and the relation between these parameters and postoperative pain were also evaluated. RESULTS: The postoperative TAS levels were significantly higher, whereas TOS and OSI levels were lower in Group 1 than Group 2. Negative correlations between oxytocin level and postoperative TOS and OSI were observed, as was a positive correlation between oxytocin level and postoperative TAS. CONCLUSIONS: The effect of ISSC and early breastfeeding on mothers was documented for the first time in this study. Our results demonstrated ISSC and early breastfeeding during C/S reduce maternal oxidative stress.

INTRODUCTION: To determine whether controlled drilling, cyst excision, and removal in a bag can reduce the operative time and intraperitoneal spillage in dermoid cysts. MATERIALS AND METHODS: Laparoscopic dermoid cyst excision was performed in 45 women using a different technique: controlled drilling of dermoid cysts in a bag, excision of these cysts, and their removal in the same bag. RESULTS: The median age of the patients was 29.5 years (range, 18-42 years), the median size of the cysts was 55 mm (range, 30-100 mm), the median operative time was 40 minutes (range, 25-60 minutes), the median level of cancer antigen 19-9 was 28.5 U/mL (range, 1.2-127 U/mL), the median parity was 1 (range, 0-3), and the median hospitalization time was 1 day (range, 1-2 days). Twenty-five cysts were in the right ovary, and 20 were in the left ovary. In all cases, the dermoid cysts were ruptured with the controlled drilling. There was no intraperitoneal spillage of the cyst contents in the abdomen. No complication occurred intraoperatively or postoperatively. There was no recurrence 3 months after the operation. CONCLUSIONS: Controlled drilling, excision, and removal of a dermoid cyst inside the same bag seems to be a feasible method to prevent intraperitoneal spillage and to reduce the operative time.

LeFort colpocleisis is a simple and effective procedure for pelvic organ prolapse in women who no longer wish to preserve coital function. If the vaginal channels created during this procedure are not large enough, blood or pus may collect within the uterus or proximal vagina. Hematocolpos, accumulation of blood in apical vagina, may be difficult to manage especially when a patient is frail and has medical comorbidities. Here, we present a case of LeFort colpocleisis in which excessive anticoagulation led to an infected hematocolpos and persistent bleeding. This was successfully managed with a Bakri balloon via a vaginal channel without recurrence of her prolapse.

Objectives. To investigate the effect of cigarette smoke exposure during intrauterine period on neonatal rat testis. Methods. Twenty-five rats were randomized to be exposed to cigarette smoke with the Walton Smoking Machine or to room air during their pregnancies. The newborn male rats (n = 21) were grouped as group 1 (n = 15) which were exposed to cigarette smoke during intrauterine life and group 2 (n = 6) which were exposed to room air during intrauterine life. The orchiectomy materials were analyzed with TUNEL immunofluorescent staining for detection of DNA damage. To detect apoptosis, immunohistochemical analyses with caspase-3 were performed. Primary outcomes were apoptotic index and immunohistochemical scores (HSCORES); secondary outcomes were Sertoli-cell count and birth-weight of rats. Results. Sertoli cell apoptosis was increased in group 1 (HSCORE = 210.6 ± 41.9) when compared to group 2 (HSCORE = 100.0 ± 17.8) (P = 0.001). Sertoli cell count was decreased in group 1 (P = 0.043). The HSCORE for the germ cells was calculated as 214.0 ± 46.2 in group 1 and 93.3 ± 10.3 in group 2 (P = 0.001) referring to an increased germ cell apoptosis in group 1. The apoptotic indexes for group 1 were 49.6 ± 9.57 and 29.98 ± 2.34 for group 2 (P = 0.001). The immunofluorescent technique demonstrated increased DNA damage in seminiferous epithelium in group 1. Conclusions. Intrauterine exposure to cigarette smoke adversely affects neonatal testicular structuring and diminishes testicular reserve.
RESUMO
PURPOSE: We evaluate the effect of stem cells to induce endometrial proliferation and angiogenesis on Asherman Syndrome (AS). METHODS: The experimental study was performed in stemcell research laboratory. Forty Wistar-Albino rats were divided according to groups. In group1 (n = 10) to establish the model; trichloroacetic acid was injected to right uterine horn. Two weeks later, intrauterine synechia was confirmed. In group2 (n = 10), 2 weeks later, 2 × 106 mesenchymal stem cells (MSC) were injected into right uterine horn followed by three intraperitoneal injections of MSCs. In group3 (n = 10), daily oral estrogen was initiated on the second week. In group4 (n = 10), MSC injections and oral estrogen was given together. The amount of fibrosis, vascularisation, inflammation and immunohistochemical staining with vascular endothelial growth factor (VEGF), proliferating cell nuclear antigen (PCNA) and Ki-67 were evaluated in the uterine tissues. RESULTS: In all treatment groups; fibrosis decreased but vascularisation and immunhistohemical stainings increased in the experimental side. The amount of fibrosis, vascularisation, Ki-67 and PCNA scores were similar between group2 and 3. In group4, comparing to group2, less fibrosis but more Ki-67, PCNA and VEGF staining was observed. CONCLUSION: Stem cells, when added to estrogen, are a highly effective alternative to induce regeneration of endometrium in Asherman Syndrome therapy.

The aim of this study was to evaluate the time-dependent effect of progesterone-only contraceptives on the brain and to obtain an improved understanding of mood disorders experienced under this medication. A total of 66 Wistar albino rats were divided into three groups: etonogestrel (ENG) implant (group 1, n = 30); depot medroxyprogesterone acetate (MPA)-injectable (group 2, n = 30); and control (group 3, n = 6) groups. Groups 1 and 2 were each divided into five subgroups, which were examined every 10 d for up to 50 d after medication administration, to evaluate its time-dependent effect. There was no difference in terms of gamma-aminobutyric acid (GABA) and serotonin immunohistochemical staining in white and gray matter among the subgroups of group 1. In group 2, there was a significant decrease in serotonin receptor staining intensity in white and gray matter on day 50, when compared to the control group (p = 0.041). When the subgroups of group 2 were compared, there was a significant decrease in serotonin receptor staining intensity in white and gray matter on days 40 and 50 when compared to day 10. In conclusion, we showed that ENG and MPA have no effect on apoptosis and GABA-A receptors in the brain. We also showed that MPA has time-dependent effects on serotonin receptors, which may be a possible mechanism involved in mood disorders during long-term usage of injectable progesterone-only contraceptives.

Pyogenic liver abscess during pregnancy is an extremely rare condition. We report a case of 33-year-old, 23-week pregnant woman with pyogenic liver abscess. She was still in the hospital for medical observation of fever, when a sudden episode of tachycardia with a pulse of 210 beats per minute and tachypnea with a respiratory rate of 30 breaths per minute was encountered. At that moment, her fever was 39.6°C (103.28 Fahrenheit). The abdominal ultrasound stated a calcific echogenic mass with a measure of 6 cm in the liver region. Given the sonographic characteristics noted, a liver abscess was suspected. Our case was successfully treated with an ultrasound guided percutaneous aspiration of the abscess and a wide spectrum antibiotic. At 38 weeks of gestation, an elective cesarean delivery was performed. The female neonate weighed 3200 g with APGAR scores of 9 and 9 at the first and fifth minutes, respectively.
RESUMO
The guidelines recently updated by the American Urological Association for the evaluation of asymptomatic microscopic hematuria (AMH) are based on data derived predominantly from men. They cannot be reliably applied to females as the epidemiology of AMH is gender dependent. The research on women in this area has been limited. It is incumbent on the experts in the field of female pelvic medicine to advance the science and develop management algorithms for AMH in women.

Apoptosis is necessary for the balance between cell proliferation and loss. Thirty-six Wistar-Albino rats were subjected to investigate apoptotic effect of widely used implantable progestins on ovarian and uterine tissues. Rats were divided into 6 groups. In the first five groups, we applied etonogestrel (IMP) subcutaneous implants (n = 30). The rats in groups were sacrificed sequentially every 10 days after application. The rats in the last group (n = 6) were accepted as controls. Apoptotic index (AI) values and Caspase-3 immunoreactivities of ovaries and uterus were recorded. In IMP groups, AI and Hscore values in stroma and glandular epithelium of uterus, granulosa and teca-lutein cells of the ovary increased with the longer progesterone exposure. Increase in AI and Hscore values were more prominent after 30 days of exposure for teca-lutein cells of ovary. Progestins increased apoptosis in ovaries and uterus by the longer exposure. Apoptosis increased in ovaries by chronic progesterone exposure. The apoptotic effect of progestin on endometrium is clear but long-term systemic application may lead to alterations in ovarian physiology. We evaluated time dependent apoptotic effect of etonogestrel on reproductive physiology and discussed progestins effect from another point of view in this study.

OBJECTIVE: To evaluate the intrauterine effect of cigarette smoke on cell death and DNA damage in follicular cells of fetal ovarian tissue. METHODS: A prospective, randomized study was conducted with 25 female wistar-albino rats. The rats were randomized to be exposed either to cigarette smoke or to room air, initiating from proestrous period and during pregnancy. Newborn female rats were categorized as Group 1 (n = 24) that had been exposed to cigarette smoke during intrauterine life and Group 2 (n = 7) that had been exposed to room air during intrauterine life. Bilateral ooferectomies were performed on the 2nd week of their life. TUNEL (in-situ Terminal Deoxynucleotidyl-Transferase Mediated dUTP-Nick-End Labeling) immunofluorescent staining and immunohistochemical analyses with caspase-3 were used for detection of DNA damage and apoptosis. Primary outcomes were apoptotic index and immunohistochemical scores (HSCORE). Secondary outcomes were ovarian follicle counts and birth weights of newborn rats. RESULTS: There was a significant increase of HSCORE and apoptotic index in Group 1. Increased immunofluorescent staining; evaluating DNA damage, with TUNEL method was observed in granulosa cells in Group 1. CONCLUSIONS: Intrauterine exposure to cigarette smoke diminishes ovarian reserve of female offspring, raising the concern about the generational impact of maternal smoking on ovarian function in the human.

OBJECTIVE: Premature labor is still the leading cause of infant mortality and morbidity worldwide. Multiple etiological factors including genetics and environment are held responsible for preterm birth. However, scientific data regarding the link between premature birth and genetics are limited. SUBJECTS AND METHODS: In this study, we included 50 women who had premature labor (group 1) but did not have any known risks for a premature delivery such as uterine anomaly, polyhydramnios, hypertension, and diabetes mellitus, and another 50 healthy women who had term labor as control (group 2). We compared these two patient groups for MTHFR C677T, MTHFR C1298T, prothrombin 20210A, factor V and ACE polymorphisms. RESULTS: We could not detect a statistical significance between groups for polymorphisms in MTHFR C677T, MTHFR C1298T, prothrombin 20210A, factor V and ACE polymorphisms. CONCLUSION: We investigated the relationship between premature and term labor and thrombophilic gene polymorphism. However, we found no associations with premature or term labor with the parameters included.
