Defining the relationship between ovarian adult granulosa cell tumors and synchronous endometrial pathology: Does ovarian tumor size correlate with endometrial cancer?

OBJECTIVE: The main feature of adult granulosa cell tumors (AGCT) is their capacity to secrete hormones, with nearly all of them capable of synthesizing oestradiol. The primary goal of this study is to identify synchronized endometrial pathologies, particularly endometrial cancer, in AGCT patients who had undergone a hysterectomy. MATERIALS AND METHODS: The study cohort comprised retrospectively of 316 AGCT patients from 10 tertiary gynecological oncology centers. AGCT surgery consisted of bilateral salpingo-oophorectomy, hysterectomy, peritoneal cytology, omentectomy, and the excision of any suspicious lesion. The median tumor size value was used to define the relationship between tumor size and endometrial cancer. The relationship between each value and endometrial cancer was evaluated. RESULTS: Endometrial intraepithelial neoplasia, or hyperplasia with complex atypia, was detected in 7.3% of patients, and endometrial cancer in 3.1% of patients. Age, menopausal status, tumor size, International Federation of Gynecology and Obstetrics stage, ascites, and CA-125 level were not statistically significant factors to predict endometrial cancer. There was no endometrial cancer under the age of 40, and 97.8% of women diagnosed with endometrial hyperplasia were over the age of 40. During the menopausal period, the endometrial cancer risk was 4.5%. Developing endometrial cancer increased to 12.1% from 3.2% when the size of the tumor was >150 mm in menopausal patients (p = 0.036). CONCLUSION: Endometrial hyperplasia, or cancer, occurs in approximately 30% of AGCT patients. Patients diagnosed with AGCT, especially those older than 40 years, should be evaluated for endometrial pathologies. There may be a relationship between tumor size and endometrial cancer, especially in menopausal patients.

The Association of ICSI Outcomes with Semen and Blood Bisphenol A Concentrations of the Male Partner.

This study investigated the association of blood and semen Bisphenol A (BPA) levels of the male partner on the reproductive outcome in intracytoplasmic sperm injection (ICSI) treatment cycles. For this prospective study (ClinicalTrials.gov identifier: NCT02703584), blood and semen samples of the male partner of the 75 women who had ICSI were analyzed. The study group consisted of men who had ICSI for male factor infertility other than azoospermia, while men with normal spermiogram whose partners underwent ICSI due to tubal factor infertility were taken as the study group. Habitual consumption of drinking water from plastic carboys/bottles (PBW) at home was also questioned in both groups as it was considered as chronic BPA exposure. The association of ICSI outcome with blood BPA (bBPA) and semen BPA (sBPA) levels was analyzed in both groups. No significant correlation was found between sperm parameters and bBPA levels in both groups. A negative correlation was found between sBPA levels and total sperm count and progressive sperm motility in men who consumed PBW. Embryo development arrest was found to be significantly higher in patients who have high sBPA levels. Although sBPA levels were not different in PBW consumers, bBPA levels were found to be significantly lower in those who consumed tap water (TW) than those who used PBW. Elevated bBPA were associated with a significant decrease in clinical pregnancy rate. Considering the widespread human exposure to BPA, the effect of BPA on the male reproductive system needs to be further examined.

Is adjuvant chemotherapy necessary for 2014 FIGO stage IC adult granulosa cell tumor?: Multicentric Turkish study.

AIM: The aim of our study is to examine the clinical, surgical, and pathological factors of stage 1C adult granulosa cell tumor (AGCT) patients and to investigate the effects of adjuvant therapy on recurrence and survival rates in this patient group. METHODS: Out of a total of 415 AGCT patients treated by 10 tertiary oncology centers participating in the study, 63 (15.2%) patients with 2014 FIGO stage IC constituted the study group. The FIGO 2014 system was used for staging. Patient group who received adjuvant chemotherapy was compared with patient group who did not receive adjuvant chemotherapy in terms of disease-free survival (DFS), and disease-specific survival. RESULTS: The 5-year DFS of the study cohort was 89%, and the 10-year DFS was 85%. Those who received adjuvant chemotherapy and those who did not were similar in terms of clinical, surgical and pathological factors, except for peritoneal cytology. In the univariate analysis, none of the clinical, surgical or pathological factors were significant for DFS. Adjuvant chemotherapy and type of treatment protocol had no impact on DFS. CONCLUSION: Adjuvant chemotherapy was not associated with improved DFS and overall survival in stage IC AGCT. Multicentric and randomized controlled studies are needed for early stage AGCT in order to confirm these results and reach accurate conclusions.

Prognostic factors of adult granulosa cell tumors of the ovary: a Turkish retrospective multicenter study.

OBJECTIVE: To define the clinical, histopathological features and the prognostic factors affecting survival in patients with adult granulosa cell tumors of the ovary (AGCT). METHODS: A 322 patients whose final pathologic outcome was AGCT treated at nine tertiary oncology centers between 1988 and 2021 participated in the study. RESULTS: The mean age of the patients was 51.3±11.8 years and ranged from 21 to 82 years. According to the International Federation of Gynecology and Obstetrics 2014, 250 (77.6%) patients were stage I, 24 (7.5%) patients were stage II, 20 (6.2%) patients were stage III, and 3 (7.8%) were stage IV. Lymphadenectomy was added to the surgical procedure in 210 (65.2%) patients. Lymph node involvement was noted in seven (3.3%) patients. Peritoneal cytology was positive in 19 (5.9%) patients, and 13 (4%) had metastases in the omentum. Of 285 patients who underwent hysterectomy, 19 (6.7%) had complex hyperplasia with atypia/endometrial intraepithelial neoplasia, and 8 (2.8%) had grade 1 endometrioid endometrial carcinoma. It was found that 93 (28.9%) patients in the study group received adjuvant treatment. Bleomycin, etoposide, cisplatin was the most commonly used chemotherapy protocol. The median follow-up time of the study group was 41 months (range, 1-276 months). It was noted that 34 (10.6%) patients relapsed during this period, and 9 (2.8%) patients died because of the disease. The entire cohort had a 5-year disease-free survival (DFS) of 86% and a 5-year disease-specific survival of 98%. Recurrences were observed only in the pelvis in 13 patients and the extra-abdominal region in 7 patients. The recurrence rate increased 6.168-fold in patients with positive peritoneal cytology (95% confidence interval [CI]=1.914-19.878; p=0.002), 3.755-fold in stage II-IV (95% CI=1.275-11.063; p=0.016), and 2.517-fold in postmenopausal women (95% CI=1.017-6.233; p=0.046) increased. CONCLUSION: In this study, lymph node involvement was detected in 3.3% of patients with AGCT. Therefore, it was concluded that lymphadenectomy can be avoided in primary surgical treatment. Positive peritoneal cytology, stage, and menopausal status were independent prognostic predictors of DFS.

Evaluation of the Success of Hysteroscopic Uterine Septum Resection.

Objectives: The aim is to use three-dimensional transvaginal ultrasonography (3-D TVUS) to evaluate the success of hysteroscopic metroplasty for the uterine septum and to compare the pregnancy outcomes. Materials and Methods: Thirty-eight patients with uterine septum who had hysteroscopic uterine septum resection were recruited. Preoperative 3-D TVUS measurements of the septal apex to the uterine fundus (s1), septal apex to internal os distance (s2), and intercornual distance (s3) were compared with the postoperative values. The pregnancies of the patients were followed up for a year postoperative period. Results: Out of the 38 patients, thirty-five had partial uterine septum (class U2a), while 3 patients had complete uterine septum (class U2b). Eighteen (47.36%) of the patients who underwent uterine septum resection achieved pregnancy, and thirteen of these pregnancies were (72.2%) term pregnancies, and all term pregnancies resulted in a live birth. Natural conception was achieved in 77.7% (14 of 18) of the patients. Term pregnancy occurred in 68.7% (11 of 16) of the patients with a partial septum and in 66.6% (2 of 3) of the patients with a complete uterine septum. A comparison of the 3-D TVUS measurements of the uterus pre- and postoperatively showed a decrease in s1 and an increase in s2 (P < 0.05). The uterine cavity length of pregnant patients was found to be higher than nonpregnant patients (P < 0.05). Conclusion: Reproductive results of hysteroscopic metroplasty were favorable in achieving live and term birth. three-dimensional TVUS can be preferred as a noninvasive effective method in objective evaluation of the success of the hysteroscopic surgery.

Factors Related to Low COVID-19 Vaccination Rate in Pregnant and Postpartum Women with and without COVID-19.

OBJECTIVE: This study focused on pregnant and postpartum women during the COVID-19 pandemic, aiming to determine the attitudes and behaviors of vaccinated and unvaccinated groups, and the vaccination behaviors in the groups with and without the disease. The reasons for refusing the vaccine were also questioned. METHODS: This cross-sectional study was performed from September 2021 to October 2021. The study data were collected using a face-to-face questionnaire. The participants were pregnant women who applied to the hospital for routine antenatal care and were hospitalized, and women in the postpartum period. Additionally, pregnant and postpartum patients who were diagnosed with COVID-19 at the time of admission and were hospitalized and admitted to the intensive care unit due to this disease were also included in the study. RESULTS: A total of 1,146 pregnant and postpartum women who completed the questionnaire were included in our study. Only 43 (3.8%) of the participants were vaccinated; 154 (13.4%) of the participants had comorbidities. The number of COVID-19-positive patients was 153. The lack of sufficient information about the safety of the COVID-19 vaccine is the most common reason for the refusal. CONCLUSION: Vaccine refusal can significantly delay or hinder herd immunity, resulting in higher morbidity and mortality. Considering the adverse effects of COVID-19 on pregnancy, it is essential to understand pregnant and postpartum women's perceptions toward vaccination to end the pandemic.

The Turkish validity and reliability of the maternal health literacy inventory in pregnancy.

BACKGROUND: There is no Turkish scale measuring maternal health literacy during pregnancy. This study adapted the Maternal Health Literacy Inventory in Pregnancy (MHELIP) to Turkish. METHODS: A methodological study's sample consisted of 500 pregnant women admitted to the antenatal clinics of a Maternity Hospital in Ankara, Türkiye. Data were collected using a personal information form, the MHELIP and the Turkish Health Literacy Index (HLI). Language, content, and construct validity were determined. Cronbach's alpha coefficient and item analysis were used to assess reliability. Equivalent-form reliability was evaluated using the HLI. RESULTS: The scale has a four-factor structure that fits well with 48 items (factor loadings: 0.57-0.92; fit index: 4.15 x2/df, 0.08 RMSEA, 0.07 SRMR). The total scale has a Cronbach's alpha of 0.96. The subscales "maternal health knowledge," "search for maternal health information," "assessment of maternal health information," and "maternal health decision making and behavior" have Cronbach's alpha of 0.96, 0.91, 0.86, and 0.94, respectively. There is a correlation between MHELIP and HLI scores (r = 0.570, p<0.001). CONCLUSION: The MHELIP is a valid and reliable tool for measuring and screening the maternal health literacy of Turkish pregnant women.

Correlation of systemic inflammation biomarkers and disease severity in pregnant women with COVID-19.

OBJECTIVE: The aim of this study was to evaluate the prognostic value of whole blood parameters, systemic inflammatory indices, and systemic inflammatory markers in pregnant women with COVID-19. METHODS: In this cross-sectional study, the demographic, clinical, and laboratory data (i.e., whole blood parameters, C-reactive protein, procalcitonin, ferritin, and D-dimer) of 464 pregnant women with COVID-19 who attended a tertiary hospital between January and April 2021 were reviewed. Systemic inflammatory indices (i.e., neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, platelet/neutrophil ratio, and systemic immune inflammation index) were calculated. Asymptomatic and mildly symptomatic pregnant women were classified as Group 1 (n=413), and those with severe disease were classified as Group 2 (n=51). RESULTS: Lymphocyte count and lymphocyte percentage in whole blood parameters were significantly lower (p<0.05), and C-reactive protein, ferritin, and procalcitonin values were higher in Group 2 (p<0.05). Systemic inflammatory indices [neutrophil/lymphocyte ratio (4.7±2.9 (1.1-21.2) vs 7.5±4.7 (2.13-23.2)), platelet/lymphocyte ratio (191.1±104.3 (53.0-807.1) vs 269.5±118.9 (105.0-756.0)), systemic immune inflammation index (1,000±663 (209-5,231) vs 1,630±1,314 (345-7,006))] were found statistically significantly higher in severe disease group (p<0.001). CONCLUSION: Evidence in this study indicates that neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and systemic immune inflammation index at first admission are simple, rapid, and inexpensive indices in predicting the prognosis of COVID-19 in pregnant women.

Clinicopathological features of atypical glandular cells, not otherwise specified, on cervicovaginal pap smears.

OBJECTIVE: The Papanicolaou (Pap) smear test is a standard screening test that detects cervical lesions and cancers. In this multicentric study, we performed a retrospective analysis of cytological results associated with atypical glandular cells, not otherwise specified (AGC-NOS). METHODS: We retrospectively reviewed Pap smear tests that resulted as AGC-NOS. A total of 254 women who underwent colposcopy due to a Pap smear result of AGC-NOS were included the study between 2003 and 2021. The ages, Pap smear results, HPV results if any, colposcopic biopsy results, endocervical and endometrial pathology results, and management of these patients were analysed. RESULTS: Two hundred fifty-four patients with AGC-NOS Pap smear results were included in the study. A total of 70 (27.6%) patients had cervical and endometrial premalignant or malignant lesions. Malignancy was observed in 17 (6.7%) patients (endometrium, n = 11 [4.3%]; cervix, n = 6 [2.4%]). Isolated premalignant or malignant lesions of the cervix and endometrium were detected in 57 (22.4%) and 12 (4.7%) patients, respectively. CONCLUSIONS: Patients diagnosed with AGC-NOS should undergo a careful evaluation with all clinicopathological features. Because cancer of the cervix and endometrium is not rare in patients diagnosed with AGC-NOS, colposcopic examination with endocervical sampling should be a priority based on a cervicovaginal smear. Endometrial sampling is also required according to the patient's clinic, age, and examination characteristics.

The effect of sacral massage on meconium-stained amniotic fluid and the duration of fetal descent in labor: A randomized controlled trial.

OBJECTIVE: The aim of this study was to investigate the effect of sacral massage on the presence of meconium-stained amniotic fluid and the duration of fetal descent during labor in pregnant women. METHODS: A total of 220 nulliparous women with singleton low-risk pregnancies in the vertex position at term were recruited. Eligible women were randomly assigned to either massage group or a control group. The massages were performed with friction and tapotement protocol. The massage was applied for 10 min each time by a midwife who is also an expert in the field, at the onset of contractions during the intrapartum period, when cervical dilatation reached 10 cm. The Wong-Baker faces pain rating scale was evaluated. RESULTS: No significant difference was found between the length of the first stage of labor and the total length of delivery (p = 0.097 and 0.434), respectively. There was a significant difference between the two groups in terms of perineal injuries. Perineal injury was lower in the massaged group (p = 0.005). There was a low percentage of meconium-stained amniotic fluid in the massaged group. The difference between the groups was statistically significant. The duration of fetal descent was shorter in the massaged group (p < 0.001). A significant difference was found in Wong-Baker FACES pain rating scale scores. Lower scores were detected in the massaged group (p < 0.001). CONCLUSION: Sacral massage has beneficial effects on mothers and babies in obstetric practice. In addition, applying massage during labor plays a significant role in reducing the presence of meconium-stained amniotic fluid and the duration of fetal descent.

The influence of COVID-19 pandemic on intrauterine fetal demise and possible vertical transmission of SARS-CoV-2.

OBJECTIVE: The impact of COVID-19 on intrauterine fetal demise (IUFD) and vertical transmission of the SARS-CoV-2 from the mother to the fetus are crucial issues of the COVID-19 pandemic. In the current study, we aimed to detect the pandemic's influence on the IUFD and evaluate the vertical transmission of the SARS-CoV-2 through analysis of placental tissues collected from PCR positive women with IUFD above 20 weeks of gestation. MATERIALS AND METHODS: The pregnant women above 20 weeks of gestation and had a fetus intrauterine demised during pandemic were included in the study. The pregnant women screened for COVID-19. Vertical transmission searched from placental tissues of COVID-19 positive women by RT-PCR tests for the presence of SARS-CoV-2 RNA. The number of IUFD before the pandemic and during the pandemic compared to assess the influence of the COVID-19 pandemic on the IUFD ratio. RESULTS: Among 138 pregnant women with IUFD, 100 of them could screen for COVID-19 status. RT-PCR test results of 6 of the screened pregnant women were positive for SARS-CoV-2. Placental tissues of these six women were analyzed, and one test result was positive for SARS-CoV-2 RNA. The IUFD ratio was significantly increased during the pandemic. CONCLUSION: It is clear that COVID-19 increases the IUFD ratio. Previous data for vertical transmission of SARS-CoV-2 during the second trimester is limited. We present the third case of literature that has positive placental results for SARS-CoV-2 RNA in the second trimester of pregnancy.

An evaluation of the results of convalescent plasma therapy applied to pregnant women diagnosed as COVID-19- positive in a pandemic center: A prospective cohort study.

BACKGROUND: Convalescent plasma (CP) might be an additional treatment modality in COVID-19. The aim of this study was to compare CP-related clinical characteristics and perinatal outcomes in pregnant women with mild or moderate-severe COVID-19. METHODS: This prospective cohort study included 36 pregnant women (12 mild and 24 moderate-severe), who underwent CP therapy. The CP obtained from recently recovered donors was transfused to patients together with maximum supportive care and antiviral agents. The groups were then compared in respect of clinical characteristics, laboratory parameters, obstetric complications, and neonatal outcomes. RESULTS: Significant differences were determined between the groups in respect of systemic corticosteroids in COVID-19 treatment (41.7%, 87.5%, p = 0.004), oxygen (O2) support (0%, 91.7%, p < 0.001), chest imaging (41.7%, 58.3%, p = 0.02), intensive care unit admission (0%, 20.8%, p = 0.03) and length of hospitalization (5.5 versus 9.5 days, p < 0.001). The O2 saturation levels before and after administration of CP were significantly lower in the moderate-severe COVID-19 group (p < 0.05). The O2 therapy time before and after administration of CP and total O2 therapy time were significantly lower in the mild COVID-19 group (p < 0.05). Platelet, plateletcrit and lymphocyte counts were significantly higher in both the mild and moderate-severe COVID-19 groups after treatment compared to the pretreatment values (p < 0.05). DISCUSSION: Although data on the results of CP treatment in pregnant women are somewhat limited, it has been suggested that early CP treatment may be associated with improvements in laboratory and ventilatory parameters in pregnant women with mild and moderate-severe COVID-19. Nevertheless, there is a need for further, randomized controlled studies on this subject with the inclusion of greater numbers of patients.

Effect of intrauterine ozone therapy on Asherman syndrome, an experimental rat model.

BACKGROUND/AIMS: Evaluate the effect of ozone therapy alone or in combination with estradiol in management of Asherman syndrome in a rat model. MATERIALS AND METHODS: 48 rats were used and divided into eight groups. In all the groups right uterine horn was used for the experiment while the left horns received no action. Groups A underwent two operations, and groups B three times each. Group 1A and 1B were determined as the sham group. Ozone gas was given to Group 2 alone; estradiol orally was given to Group 3 alone; estradiol and ozone gas together was given to Group 4. RESULTS: In ozone therapy group; the diameter of the uterus, the uterine lumen and the uterine glands were increased, the endometrial epithelium was thicker in the group that received double ozone application, and the number and diameter of the endometrial gland increased in the combined use of ozone and estradiol. In the rats who underwent two surgeries, the maximum number of pregnancies and advanced pregnancies were observed in the left uterine horn. The minimum number of pregnancies were achieved in estradiol alone group. In the group receiving combined treatment with ozone and estradiol, pregnancies were observed at a higher gestational age. CONCLUSION: Ozone had a positive effect on the treatment of Asherman syndrome and has a significant impact on achieving pregnancy.

The Impact of Elevated Liver Enzymes and Intrahepatic Cholestasis of Pregnancy on the Course of COVID-19 in Pregnant Women.

This study aims to investigate the perinatal outcomes in COVID-19 pregnant women with intrahepatic cholestasis of pregnancy (ICP) and elevated liver enzymes. Present study was carried out on pregnant women with COVID-19 between March 11, 2020, and August 11, 2021. Patients with liver enzyme levels higher than twice the upper limit of the reference range for aspartate aminotransferase(AST) and/or alanine aminotransferase (ALT) were included. Patients with unexplained pruritus and elevated fasting biliary acid (FBA) levels were considered ICP. The remaining cases were used as the control group. There were a total of 1751 patients in the study period. Among them, 126 had elevated liver enzymes. Nineteen of these cases had also ICP. AST and ALT values were statistically higher in the ICP group. Demographic features, clinical characteristics, and perinatal outcomes were similar between the groups. The rate of ICP in pregnant women with COVID-19 was similar to the literature in this study. Although the preterm delivery rates for both groups were higher than in the current literature, the preterm delivery rates in the study and control groups were similar. Elevated liver enzymes can be observed in pregnant women with COVID-19 with higher rates of preterm delivery compared to the previous literature. However, the diagnosis of ICP in addition to elevated liver enzymes seems to have no significant impact on the perinatal outcomes. Future studies conducted on larger populations are necessary to confirm these results.

The Association of Serum Electrolytes with Disease Severity and Obstetric Complications in Pregnant Women with COVID-19: a Prospective Cohort Study from a Tertiary Reference Center.

Introduction To evaluate the association of serum electrolytes with disease severity and obstetric complications in pregnant women with Coronavirus disease 2019 (COVID-19). Materials and Methods This prospective cohort study was conducted on pregnant women with confirmed COVID-19. Study population was divided into two groups: 1) Mild COVID-19 group (n = 811) and 2) Moderate/severe COVID-19 group (n = 52). Demographic features, clinical characteristics, obstetric complications, and serum electrolytes were compared between the groups. Afterward, a correlation analysis was performed to investigate the association between serum electrolyte disturbances with COVID-19 severity and obstetric complications. Results Highest serum sodium, hypernatremia, potassium replacement, hypopotassemia, hyperchloremia, initial serum magnesium, hypermagnesemia, and hypocalcemia were significantly higher in the moderate/severe COVID-19 group. The lowest serum sodium, lowest serum potassium, and initial serum calcium were significantly higher in the mild COVID-19 group (p < 0.05). Statistically significant positive weak correlations were found between hypernatremia, hypopotassemia, hyperchloremia, hypermagnesemia, hypocalcemia and COVID-19 severity (r values were 0.27, 0.20, 0.12, 0.18 and 0.12, p values were < 0.001, < 0.001, 0.02, 0.03 and 0.03, respectively). Furthermore, statistically significant positive weak correlations were found between hypopotassemia, hypochloremia, hypermagnesemia, and obstetric complications (r values were 0.10, 0.10, and 0.28, p values were 0.004, 0.03, and 0.001, respectively). A statistically significant negative weak correlation was found between hypomagnesemia and obstetric complications (r = - 0.23 and p = 0.01, respectively). Conclusion Electrolyte disturbances in pregnant women with COVID-19 seem to be associated with disease severity and obstetric complications.

Comparison of clinical features and perinatal outcomes between pre-variant and post-variant periods in pregnant women with SARS-CoV-2: analysis of 1935 cases.

PURPOSE: To compare the clinical features and perinatal outcomes of pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the pre-variant and post-variant periods. METHODS: This prospective cohort study includes pregnant women with SARS-CoV-2 who were followed-up at Ankara City Hospital between 11, March 2020 and 15, September 2021. Demographic features, clinical characteristics and pregnancy outcomes were compared between the pre-variant (n = 1416) and post-variant (n = 519) groups. RESULTS: The rates of severe and critical cases significantly increased in the post-variant group (9.7% vs 2%, p < 0.001). The rates of respiratory support (26.8% vs 7.3%, p < 0.001), ICU admission (12.9% vs 1.8%, p < 0.001) and maternal mortality (2.9% vs 0.4%, p < 0.001) were significantly higher in the post-variant group. A significant increase was observed for pregnancy complications in the post-variant group (45.6% vs 18.8%, p = 0.007). The rates of preterm delivery (26.4% vs 4.4%, p < 0.001) and NICU admission (34% vs 18.8%, p < 0.001) were significantly higher in the post-variant group. Positive, weak, statistically significant correlations were observed between the post-variant period, disease severity and maternal mortality (r = 0.19, r = 0.12 and p < 0.001). CONCLUSION: Post-variant COVID-19 period was associated with a severe course of the disease and increased rates of adverse obstetric outcomes in pregnant patients.

Evaluation of embryo transfer through a scoring system: ETSS (Embryo transfer scoring system).

INTRODUCTION: To create a scoring system by including all of the factors that are recommended for an ideal ET and to investigate its correlation with the Β-HCG results. MATERIALS AND METHODS: This study was conducted as a retrospective trial between January 2009 and December 2018. Women who had a single ET between the specified dates were included in the study. The embryo grade, ET day, distance between the fundus to embryo transfer site measured via ultrasonography, endometrial thickness on ET day, and presence of mucus and blood in the catheter after transfer were the variables evaluated. Each one of the five variables that constituted the scoring system were rated separately. RESULTS: Overall, 1652 patients participated in this research. Antral follicle count (13,3 ± 8 vs. 14,6 ± 8,2, p: 0,001), endometrial thickness on the ET day (9.9 ± 2 vs.10.3 ± 2, p = 0.006) and number of mature oocytes (8.6 ± 6 vs. 9 ± 5.1, p: 0.003) were significantly higher in patients with positive Β-HCG values. The total score in the Β-HCG positive group was 9.8 ± 1.4 versus 8.9 ± 1.4 in the Β-HCG negative group (p < 0.001). The best ETSS cut-off value for predicting Β-HCG positivity was 9.5, with 82% sensitivity and 67% specificity (AUC:0.808). CONCLUSION: Our scoring system is an important step toward standardization, as it offers a new, practical, cost-free, and applicable scoring system based on pre- and post-ET measurements and laboratory data.

Fertilization and early embryonic development of in vitro matured metaphase I oocytes in patients with unexpected low oocyte maturity rate.

To determine the fertilization and embryonic potential of immature metaphase I (MI) oocytes in patients with low oocyte maturity rate in whom the percentage of mature oocytes obtained was less than 75% of the total retrieved ones. In vivo matured metaphase II (MII) oocytes (MII-ICSI, n = 244), and in vitro matured MI oocytes (MI-MII-ICSI, n = 202) underwent an intracytoplasmic sperm injection (ICSI) procedure. Maturation rate, fertilization rate and early embryonic development were compared in both groups. In total, 683 oocytes were collected from 117 ICSI cycles of 117 patients. Among them, 244 (35.7%) were mature MII and 259 (37.9%) were MI after the denudation process. Of those 259 MI oocytes, 202 (77.9%) progressed to MII oocytes after an incubation period of 18-24 h. The maturation rate was 77.9%. Fertilization rate was found to be significantly higher in the rescued in vitro matured MI oocyte group when compared with the in vivo matured MII oocyte group (41.6% vs 25.8%; P = 0.0006). However, no significant difference was observed in terms of cleavage rates on days 2 and 3 between the groups (P = 0.9126 and P = 0.5031, respectively). There may be unidentified in vivo factors on the oocyte maturation causing low developmental capacity in spite of high fertilization rates in the group of patients with low oocyte maturity rate. Furthermore, studies are needed to determine the appropriate culture characteristics as well as culture period and ICSI timing of these oocytes.
