Objective: To explore the safety and long-term efficacy of transvaginal reconstructive pelvic surgery (TVRPS) in ≥70-year-old women with severe pelvic organ prolapse (POP). Methods: A single-center, prospective cohort study was conducted on 343 elderly women patients with severe POP who received TVRPS at the Fourth Medical Center, Chinese PLA General Hospital, Medical School of Chinese PLA from March 2007 to September 2024. There were 297 cases (86.6%, 297/343) of Ⅲ degree and 46 cases (13.4%, 46/343) of Ⅳ degree prolapse respectively. Among them, anterior pelvic prolapse accounted for 80.8% (277/343), and those with prolapse in two or more sites accounted for 30.0% (103/343). The age was (74.2±3.4) years (range: 70 to 89 years old). There were 300 cases (87.5%, 300/343) with more than one internal medicine disease. Preoperative general conditions were assessed using American Society of Anesthesiologists physical status classification system (ASA) and American College of Surgeons National Surgical Quality Improvement Program-frailty index (ACS NSQIP-FI). TVRPS surgeries included transvaginal hysterectomy, salpingooophorectomy, high uterosacral ligament suspension, sacrospinous ligament fixation, native tissue and mesh repair of the anterior and posterior vaginal walls, mid-urethral sling for anti-urinary incontinence, and levator anal muscle folding suture and perineal repair. Perioperative complications were evaluated using Clavien-Dindo classification system. The objective effect of TVRPS was determined based on pelvic organ prolapse quantification system (POP-Q), and the subjective results were evaluated using pelvic floor distress inventory-short form 20 (PFDI-20), pelvic floor impact questionnaire-short form 7 (PFIQ-7) and patient global impression of improvement (PGI-I). Results: All patients had a preoperative ASA grade of ≤gradeⅡ, and ACS NSQIP-FI score of ≤0.27. All patients safely and successfully underwent all TVRPS surgeries. The operation time was (154.2±43.2) minutes. The perioperative morbidity and mortality rate were 0.6% (2/343) and 0 (0/343) respectively. None of the patient needed blood transfusion. The follow-up time was (7.5±4.3) years, with the longest being 17 years. Thirty-four cases (9.9%, 34/343) were lost to follow-up, and 22 cases (6.4%, 22/343) died of internal diseases during the follow-up period. The point values of Aa, Ba, C, Ap and Bp in the POP-Q system were significantly decreased after the operation (all P<0.01), the genital hiatus was significantly shortened (all P<0.01), and the perineal body was significantly elongated (all P<0.01). The scores of PFDI-20 and PFIQ-7 were significantly lower than those before the operation (all P<0.01). There were 332 cases (96.8%, 332/343) with an overall symptom impression improvement score of PGI-I≤2. Conclusion: The results on 343 elderly women with severe POP aged an average of 74.2 years show that for elderly

Objective: To investigate the impact of the number of cesarean deliveries on adverse maternal and neonatal outcomes. Methods: A retrospective analysis was conducted on 11 904 singleton pregnant women who underwent cesarean delivery at the Third Affiliated Hospital of Guangzhou Medical University from January 1st, 2019 to December 31st, 2023. The women were grouped according to the number of cesarean deliveries: those undergoing their first cesarean delivery (1CD group, 7 231 cases), those undergoing their second cesarean delivery (2CD group, 3 749 cases), those undergoing their third cesarean delivery (3CD group, 841 cases), and those undergoing their fourth or more cesarean deliveries (4CD group, 83 cases). Differences in clinical characteristics, related surgical procedures, and adverse maternal and neonatal outcomes among the groups were compared. Binary logistic regression analysis was used to assess the impact of the number of cesarean deliveries on related surgical procedures and adverse maternal and neonatal outcomes. Results: (1) During the 5-year period, the total number of women undergoing cesarean delivery in our hospital showed a slight downward trend, while the proportion of women undergoing three or more cesarean deliveries increased. (2) Compared with women undergoing their first cesarean delivery, women in each repeat cesarean delivery group were older, had higher proportions of advanced maternal age and pre-pregnancy body mass index, and had more pregnancies, deliveries, and induced abortions; the incidence of placenta previa, placental implantation, antepartum hemorrhage, gestational hyperglycemia, and failed trial of labor requiring conversion to surgery was higher, while the incidence of premature rupture of membranes was lower; the proportions of ureteral stent placement, adhesiolysis of the pelvic and abdominal cavities, uterine rupture, uterine reconstruction, uterine artery ligation, hysterectomy, postpartum hemorrhage, and postoperative intestinal obstruction were higher, and the amount of postpartum hemorrhage was greater; the gestational age at delivery of neonates was earlier, but the rates of preterm birth at 28-31⁺⁶ and 32-33⁺⁶ weeks of gestation were lower; the differences were statistically significant (P<0.05) for all comparisons. (3) The number of cesarean deliveries was not an independent risk factor for the dose-dependent occurrence of placenta previa (aOR=0.99, 95%CI: 0.98-1.01; P=0.261). In women without placenta previa, the number of cesarean deliveries was not a risk factor for placental implantation (aOR=1.12, 95%CI: 0.90-1.39; P=0.320). However, in women with placenta previa, the number of cesarean deliveries was a risk factor for placental implantation (aOR=4.01, 95%CI: 3.08-5.22; P<0.001). In the overall population, the number of cesarean deliveries was a risk factor for ureteral stent

Objective: To investigate the effect of pre-pregnancy body mass index (BMI) on the cumulative live birth rate (CLBR) and perinatal outcomes in women with polycystic ovary syndrome (PCOS) undergoing first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI). Methods: The clinical data of 1 013 patients with PCOS who received first IVF/ICSI treatment in Reproductive Medicine Center, Henan Provincial People's Hospital from January 2017 to June 2020 were retrospectively analyzed. According to BMI China standard, they were divided into: normal weight group (18.5≤BMI<24.0 kg/m², 388 cases), overweight group (24.0≤BMI<28.0 kg/m², 367 cases), obese group (BMI≥28.0 kg/m², 258 cases). The effect of BMI on CLBR was analyzed by univariate analysis, multivariate logistic regression analysis and smooth curve fitting. The role of homeostasis model assessment of insulin resistance index (HOMA-IR) in the process of BMI on CLBR was analyzed by mediation analysis. Results: Among three groups, female age, basal level of follicle stimulating hormone, type of infertility and ovulation induction regimens were similar (all P>0.05). The infertility duration, basal testosterone level, HOMA-IR, the ovulation induction time and the total gonadotropin dosage increased with BMI (all P<0.01), anti-Müllerian hormone, basal luteinizing hormone level, the number of retrieved oocytes and available embryos decreased with BMI (all P<0.05). CLBR decreased with BMI increasing [84.08% (301/358) vs 74.26% (251/338) vs 71.88% (161/224); P<0.001]. The incidence of hypertensive disorder in pregnancy was highest in obese group, while premature rupture of membranes rate, premature delivery rate, low birth weight rate and macrosomia birth rate were the lowest in normal weight group. After adjusting for confounding factors, both smooth curve fitting and multiple logistic regression analysis revealed a significant trend: CLBR declined with increasing BMI (OR=0.93, 95%CI: 0.89-0.97; P=0.002), with a reduction of 41% (OR=0.59, 95%CI: 0.39-0.91; P=0.020) in overweight group, and a reduction of 48% (OR=0.52, 95%CI: 0.32-0.83; P=0.010) in obese group. HOMA-IR mediated the effect of BMI on CLBR by 27.5% (P<0.05). Conclusions: High BMI before IVF/ICSI in PCOS patients negatively impacts CLBR and raises maternal and infant risks during pregnancy and the perinatal period. 27.5% of the effect of BMI on CLBR is mediated by HOMA-IR. Thus, PCOS patients should manage their BMI and enhance insulin sensitivity prior to pregnancy.

Objective: To investigate the relationship between postpartum hemorrhage (PPH) volume and the risk of adverse clinical outcomes in pregnant women. Methods: This was a retrospective cohort study of 41 494 deliveries at Peking University Third Hospital from 2012 to 2020. With PPH volume as the main exposure, the outcome indicators included: (1) Severe adverse outcomes: shock or embolism, abnormal coagulation function, abnormal liver function, and kidney injury; (2) General adverse outcomes: moderate to severe anemia, hypoalbuminemia, postpartum blood transfusion. Robust Poisson regression was employed to calculate the risk of each outcome index in pregnant women with different PPH volumes under the condition of controlling confounding factors, and to analyze the risk trends of each outcome index with the change of PPH volumes. Results: A total of 41 494 pregnant women were included in the study, including 9 959 cases (24.00%, 9 959/41 494), 23 974 cases (57.78%, 23 974/41 494), 5 235 cases (12.62%, 5 235/41 494), 1 144 cases (2.76%, 1 144/41 494), 508 cases (1.22%, 508/41 494), 208 cases (0.50%, 208/41 494), 207 cases (0.50%, 207/41 494) and 259 cases (0.62%, 259/41 494) pregnant women with PPH volume <250, 250-499, 500-749, 750-999, 1 000-1 249, 1 250-1 499, 1 500-1 999 and ≥2 000 ml, respectively. The risk of any serious adverse outcome, such as shock or embolism, abnormal coagulation function, abnormal liver function and kidney injury, showed a "J-shaped" relationship with PPH volume: risks remained stable (0.26%-0.59%) below 1 500 ml but increased significantly to 3.38% (RR=3.43, 95%CI: 1.14-10.35) at 1 500-1 999 ml and 5.02% (RR=4.53, 95%CI: 1.49-13.75) at ≥2 000 ml (all P<0.05). Moderate-to-severe anemia showed threshold effects at 750 ml (RR ranging from 7.21 to 8.53) and hypoalbuminemia at 1 250 ml (RR ranging from 3.24 to 3.83), with risks plateauing beyond these thresholds (all P<0.05). Conclusion: It is suggested that 750 ml, 1 250 ml and 1 500 ml should be used as the key intervention thresholds, corresponding to the initiation thresholds of anemia, hypoalbuminemia management and multidisciplinary intensive care, respectively, so as to provide a new reference for optimizing the clinical diagnosis and treatment strategy of PPH.

Objective: To investigate the predictive value of the cancer antigen 125 (CA₁₂₅) elimination rate constant K (KELIM) score for no visible residual disease (R0) and prognosis in high-grade serous ovarian carcinoma (HGSOC) patients undergoing neoadjuvant chemotherapy (NACT)+interval debulking surgery (IDS). Methods: A retrospective analysis was conducted on 78 HGSOC patients treated with NACT+IDS at Beijing Hospital, from June 2014 to June 2024. The KELIM score was calculated, and its predictive value for R0 resection, chemotherapy response score (CRS), platinum-free interval (PFI), progression-free survival (PFS) time, and overall survival (OS) time was analyzed. Results: (1) The mean age at diagnosis was (61.9±9.9) years. The mean KELIM score was 1.1±0.4, with 44 patients having KELIM score≥1 and 34 having KELIM score <1. (2) Patients with KELIM score ≥1 had significantly higher rates of R0 resection (84% vs 56%; P=0.006), CRS3 grading (41% vs 0; P<0.001), and PFI ≥6 months (84% vs 53%; P=0.04) compared to those with KELIM score <1. Additionally, the median PFS time (18.7 vs 13.2 months; P<0.001) and OS time (34.8 vs 29.9 months; P=0.007) were significantly longer in the KELIM score ≥1 group. Chemosensitivity: patients with PFI <6 months had a significantly lower median KELIM score than those with PFI ≥6 months (0.8 vs 1.2; P=0.005). Surgical outcome: patients achieving R0 resection had a significantly higher median KELIM score than those without R0 (1.2 vs 0.7; P<0.001). (3) Univariate analysis identified non-R0 resection, CRS3 grading, lack of poly adenosine diphosphate ribose polymerase (PARP) inhibitor maintenance therapy, and KELIM score <1 as significant risk factors for OS time (all P<0.05). Multivariate analysis confirmed non-R0 resection (HR=3.78,95%CI: 1.13-12.66; P=0.031), no PARP inhibitor maintenance (HR=7.41,95%CI:1.82-30.15; P=0.005), and KELIM score <1 (HR=5.14,95%CI:1.41-18.72; P=0.013) as independent risk factors for OS time. Conclusions: The KELIM score may serve as a predictive marker for chemosensitivity, R0 resection, PFS time, and OS time in HGSOC patients undergoing NACT+IDS. KELIM score<1 is an independent risk factor for OS.

Objective: To explore the effectiveness and application value of focused ultrasound ablation surgery (FUAS) combined with hysteroscopic surgery in treating solitary type Ⅱ submucosal uterine fibroids with maximum diameter >5 cm. Methods: Clinical data of 35 patients with a single type Ⅱ submucosal uterine fibroid with maximum diameter greater than 5 cm who underwent FUAS combined with hysteroscopic surgery at Qingdao Women and Children's Hospital from June 2020 to December 2023 were collected. The clinical characteristics, treatments and treatment outcomes were retrospectively analyzed. Results: (1) Clinical characteristics: the mean age of the 35 patients was (36.7±6.6) years, with a median maximum diameter of fibroids of 56 mm (range: 51-80 mm). All patients presented with symptoms of menorrhagia, median menstrual bleeding score was 5 points (ranged from 3 to 5 points), and 34 cases (97.1%, 34/35) had concomitant anemia, the mean hemoglobin was (83.1±13.8) g/L of 35 patients. (2) Treatments: all 35 patients underwent FUAS treatment initially, with a lesion ablation rate ranging from 69.7% to 97.9% (median:90.7%), and no complications occurred. After FUAS treatment, the volume of fibroids decreased in all patients, with a volume reduction rate ranging from 30.57% to 87.22% (median:76.03%). Hysteroscopic surgery was performed 3-14 months (median: 5 months) after FUAS to remove the necrotic fibroid tissue, achieving a 100.0% (35/35) fibroid resection rate. Only 1 patient developed complications of hyperhyderation syndrome during hysteroscopic surgery, and no complications occurred in the remaining patients. (3) Evaluation of efficacy: after FUAS pretreatment, the maximum diameter of fibroids in the 35 patients decreased significantly (Z=-5.171, P<0.001), as did the volume of fibroids (Z=-5.159, P<0.001). The hemoglobin level increased significantly compared to the level before FUAS in all cases (t=-8.657, P<0.001), and median menstrual bleeding score decreased to 2 points (range: 1-3 points), significantly lower than original level (Z=-5.292, P<0.001). At the 3-month follow-up after hysteroscopic surgery, all patients were free of anemia symptoms, with menstrual bleeding scores totally decreased to 1 point, significantly lower than that before hysteroscopic surgery (Z=-4.786, P<0.001); hemoglobin level [(118.7±5.6) g/L] significantly increased compared to that before hysteroscopic surgery (t=-9.258, P<0.001). All patients underwent gynecological transvaginal ultrasound re-examination, which did not reveal any residual fibroids. Conclusion: FUAS combined with hysteroscopic surgery is effective in treating solitary type Ⅱ submucosal uterine fibroids with maximum diameter >5 cm, providing a new treatment option for patients.
