Objectives: The luteal phase supplementation (LPS) of the in vitro fertilization (IVF) cycle is crucial to increase the chance of a live birth. There is no preferred progestogen for use in the general population. The optimal progestogen regimen in the event of prior IVF failure is unknown. The aim was to compare the live birth rate for dydrogesterone plus progesterone gel versus aqueous progesterone plus progesterone gel in LPS of the IVF cycle in women with at least one previous IVF failure.

Material and methods: A prospective randomized single-center study enrolled women with at least one previous IVF failure undergoing another IVF cycle. Women were randomly assigned in a 1:1 ratio to 2 arms depending on LPS protocol: dydrogesterone (Duphaston®) + progesterone in vaginal gel (Crinone®) vs aqueous progesterone solution in subcutaneous injection (Prolutex®) + progesterone in vaginal gel (Crinone®). All women underwent fresh embryo transfer.

Results: The live birth rate with one prior IVF failure was 26.9% for D + PG vs 21.2% for AP + PG (p = 0.54), and with at least two IVF failures: 16% for D + PG vs 31.1% for AP + PG (p = 0.16). There were no significant differences in live birth rates between protocols, regardless of the number of prior IVF failures.

Conclusions: In light of the evidence from this study that neither of the two LPS protocols is more effective in women with prior IVF failure, other factors, such as potential side effects, dosing convenience and patient preference, should be considered when choosing a treatment.

Objectives: With the increasing rate of cesarean operations, the formation of niches and related early and late complications have been observed more frequently. In this study, we examined the effects of using a suture material that can be absorbed faster than conventional sutures on the formation of niches.

Material and methods: This study was designed as a retrospective study and completed with a total of 101 patients. During the cesarean operation, the uterus was closed with Rapide Vicryl® in 49 patients and Vicryl® in 52 patients. The uterine niche was measured with a sonohysterogram 6 months after the operation. The primary outcome of the study was determined as uterine niche formation and the secondary outcome was the post-menstrual spotting (PMS) rate.

Results: Duration of surgery, intraoperative/postoperative blood loss, and hospitalization time were similar between the two groups. Niche formation was significantly lower in the Rapide Vicryl group (22.4%) when compared to the Vicryl group (42.3%) (p = 0.046). Also, PMS was observed significantly lower in the Rapide Vicryl group (16.2% and 52.8% in Rapide Vicryl and Vicryl groups, respectively; p = 0.002).

Conclusions: The formation of niches and associated PMS rates were less with suture materials that were absorbed faster.

Objectives: The aim of this study was to investigate the relationship between levels of brain-derived neurotrophic factor (BDNF), which is considered a cause of conditions such as depression and eating disorders, and hyperemesis gravidarum (HG).

Material and methods: This study was conducted as a prospective study at Ankara Ataturk Training and Research Hospital in the Department of Obstetrics and Gynecology. The study included 73 pregnant women with singleton pregnancies (32 pregnant women with HG and 41 pregnant women without hyperemesis). Serum BDNF levels were compared between the two groups.

Results: The mean age of the study group was 27.3 ± 3.5 years and the body mass index (BMI) was 22.4 ± 2.7 kg/m². There is no statistically significant difference between the study group and the control group in terms of demographic data (p > 0.05). The pregnant women with HG were found to have significantly higher serum BDNF levels compared to the control group (349.1 ± 94.6 pg/mL vs 292. 3± 86.01, p = 0.009) CONCLUSIONS: Serum BDNF levels that are low in psychiatric disorders such as depression or anxiety were found as high in pregnant women with HG.

Objectives: Placenta accreta spectrum (PAS) is usually treated by hysterectomy performed through a midline incision. We hypothesize that PAS surgery can be performed through a Joel-Cohen incision with adequate sight and safety.

Material and methods: The data on women having a hysterectomy due to PAS between 2013-2021 was collected retrospectively. Operation length, baby's pre-delivery general anesthesia exposure time, transfusion rates, complication rates, postoperative admission to the intensive care unit (ICU), postoperative hospital stay, and neonatal outcomes were collected. In addition, the data investigated whether the operation was performed under emergent conditions and in the early (2013-2016) or late (2017-2021) years.

Results: 161 patients met the inclusion criteria. The median gestational age at delivery was 34 weeks (27-39). The mean operation length was 150 minutes (75-420), and the anesthesia-to-delivery interval was 32 minutes (5-95). Twenty-three (14%) patients did not receive any blood product, 73 (45%) received less than three packs of erythrocyte, and only seven (4%) had a massive transfusion. Bladder injuries occurred in 24 (15%). Preoperative anemia, hypogastric artery ligation, transfusion, ICU admission, and maternal and neonatal complications were more frequent in emergent cases. Comparison between the early and late groups showed a decrease in the rate of anemia, maternal ICU admission, hypogastric artery ligation, and neonatal complications. In addition, infectious complications were relatively rare in all groups.

Conclusions: The Joel-Cohen incision and bladder dissection before the baby's delivery reduce transfusion rates and avoid midline incision, which is prone to complications and unpleasant cosmetic appearance while performing a hysterectomy for PAS surgery.

Vulvar lichen sclerosus is chronic and difficult to treat disorder, which offer is recurrent and leads to multiple complications. The limited efficacy of pharmacologic treatment directed the search for new therapies including use of CO₂ laser. In our study we focused on collagen and elastin gene expression as well as heat shock proteins and p53 expression in two patients with vulvar lichen sclerosus who underwent CO₂ laser therapy. In both patients we observed decreased clinical symptoms observed by an experienced gynecologist as well as significant changes in gene expression before and after laser treatment.

Objectives: The aim of this study is to analyze correlation between vitamin D level and BMI in polycystic ovary syndrome (PCOS) women.

Material and methods: The study group consisted of 311 patients with PCOS. Patients were categorized according to four phenotypes. All of the women participating in the study had their blood tested in the appropriate phase of the menstrual cycle and after proper preparation for the tests. The ultrasound examination and anthropometric measurements were performed.

Results: Vitamin D concentration was assessed in all study subgroups. The majority of patients had vitamin D deficiency or insufficient level. Variables included in the study, such as level of vitamin D, low density lipoprotein (LDL), sex hormone binding globulin (SHBG), testosterone, androstenedione, Anti-Müllerian Hormone (AMH) and BMI were correlated. A negative correlation was observed with the the level of SHBG, vitamin D and AMH. Subsequently, positive correlations were shown with testosterone, LDL and free testosterone level. An analysis of the correlation between BMI and vitamin D concentration showed that in phenotype I of PCOS this correlation was statistically significant and in the remaining PCOS phenotypes the correlation was close to statistical significance.

Conclusions: Most PCOS patients have a deficiency or insufficient level of vitamin D. Women with PCOS have shown a significant negative correlation between BMI and SHBG serum level and between BMI and AMH level. A positive correlation exists between BMI and total and free testosterone and LDL. There is a negative correlation between BMI and vitamin D level in PCOS patients and in phenotype I this correlation was statistically significant.

Objectives: To explore the relationship between the distance from the lower edge of the gestational sac to the internal cervical os in early pregnancy and placenta previa.

Material and methods: A prospective cohort study of women who underwent pregnancy examination in Weifang People's Hospital or Sunshine Union Hospital from January 2020 to June 2021. The distance from the lower edge of the gestational sac to the internal cervical os was measured at 5-6 weeks' gestation. There were 86 women with distance < 2.5 cm, and 105 women with distance ≥ 2.5 cm were randomly selected. There were 92 cases of scarred uterus and 99 cases of non-scarred uterus among the 191 women. They were divided into six groups according to the distance: (1) < 1.0 cm; (2) 1.0 cm to < 1.5 cm; (3) 1.5 cm to < 2.0cm; (4) 2.0 cm to < 2.5 cm; (5) 2.5 cm to < 3.0 cm; (6) ≥ 3.0 cm. All included women were followed-up during pregnancy and pregnancy outcome, and the likelihood ratio of different distances in early pregnancy was calculated and risk stratification was performed, and ROC curve was constructed.

Results: There were 15 women in the included studies who were lost to follow-up, 47 had a scarred uterus with placenta previa and 29 had a non-scarred uterus with placenta previa after delivery at 28 weeks or later. The distance from the lower edge of the gestational sac to the internal cervical os in early pregnancy of the scarred uterus < 1.5 cm, and the likelihood ratio was ∞; and the distance ≥ 3.0 cm, the likelihood ratio was 0. The distance from the lower edge of the non-scarred gestational sac to the internal cervical os < 1.0 cm, and the likelihood ratio was ∞; and the distance ≥ 3.0 cm, the likelihood ratio was 0. The ROC curve showed that when the area AUC under the curve was 87%, the optimal diagnostic cut-off value was 2.4 cm.

Conclusions: When the distance from the lower edge of the gestational sac to the internal cervical os was < 1.5 cm and the distance between the non-scarred uterus was < 1.0 cm, it eventually developed into placenta previa; the distance from the lower edge of the gestational sac to the internal cervical os in the first trimester of pregnancy between the scarred uterus and the non-scarred uterus was ≥ 3.0 cm, and it would hardly develop into placenta previa. When the distance from the lower edge of the gestational sac to the internal cervical os in early pregnancy was ≤ 2.4 cm, it could be used as a predictor of placenta previa.

Objectives: To investigate the prevalence and influencing factors of stress urinary incontinence (SUI) within 6-8 weeks postpartum in Jiangsu Province.

Material and methods: We designed a multi-center cross-sectional study involving seven hospitals in Jiangsu province, and enrolled women who underwent postpartum examination at 6-8 weeks in these hospitals between July 2019 and June 2021. According to the presence or absence of SUI, the enrolled patients were divided into two groups: the SUI group and the non-SUI group, respectively. We assessed the general health status, noted the details of delivery, and checked the pelvic floor electromyographic parameters of the postpartum women in both groups.

Results: Among 6,302 cases of postpartum women in Jiangsu province, there were 1,579 cases of SUI, with a prevalence of 25.06%. The prevalence of SUI increased significantly with age, BMI, increasing parity, coexisting constipation, organ prolapse, and diastasis recti abdominis. Compared to the non-SUI group, the SUI group had a lower mean value of the pre-baseline rest phase, shorter rise and fall times of fast muscle contractions, and a lower mean value of the endurance contraction phase. Multiple regression analysis revealed associations with weight (especially overweight and obesity), coexisting organ prolapse, constipation, parity, gestational week of delivery, mode of delivery, and mean value of endurance contraction phase.

Conclusions: The prevalence of postpartum stress urinary incontinence in Jiangsu Province was 25.06%, and was linked to being overweight, parity > 2, coexisting organ prolapse, constipation, and a decrease in the mean value of the endurance contraction phase of the electromyograph. In this report, we offer a theoretical basis for the effective prevention of postpartum SUI clinically.
