Purpose: In preimplantation genetic testing for monogenic/single gene disorders (PGT-M) cycles, direct detection of the pathogenic mutation combined with indirect haplotype analysis are recommended to achieve accurate diagnosis. However, it poses a challenge to conduct haplotype analysis for patients carried de novo pathogenetic mutations or without no identified haplotype in families. Herein, the strategy of affected-embryo-based haplotype analysis was implemented in clinical practice to provide a convenient, economical and effective way for such patients.

Materials and methods: Eight cases with de novo mutations were recruited. Six cases found the embryo-proband from biopsied blastocysts, and two case (case5 and 6) found them from developmental arrested embryos. A total of thirty-seven biopsied blastocysts from eight PGT-M cycles were performed direct detection and affected-embryo-based single nucleotide polymorphism (SNP) haplotype analyses.

Results: Till now, five cases (case 1, 2, 3, 7, 8) had delivered healthy babies and one case (case6) achieved successful ongoing pregnancy. We reported for the first time to find proband from developmental arrested embryos to complete haplotype analyses when no carriers were found in biopsied ones in clinical practice.

Conclusion: Our study further proves and expands the application of the double-checking strategy based on affected-embryo proband and allows patients with de novo mutations or lack positive family members to benefit from the strategy.

Purpose: Diagnostic challenges in colposcopy arise especially in women aged 50 or older, with postmenopausal status and transformation zone type 3 (TZ3). Endocervical curettage (ECC) is a valuable tool for diagnosing intracervical lesions. The aim of this retrospective analysis was to evaluate the use of ECC in colposcopy for detecting cervical intraepithelial lesions.

Methods: A retrospective study was carried out of colposcopies performed in the certified Dysplasia Unit at Erlangen University Hospital between July 2016 and June 2023. Pap and human papillomavirus (HPV) results were correlated with the histologic findings via ECC, obtained during examinations or surgery. The primary outcome was the rate of accuracy between the colposcopic and histologic findings with regard to cytology, age of patients, and type of transformation zone (TZ).

Results: A total of 429 colposcopies in 413 women with histologic samples obtained via ECC were included in the final analysis. In all, 355 women had TZ3. Among patients with TZ3, evidence of high-grade lesions and invasive carcinoma was also found in women with normal or low-grade abnormal cytology. For patients with normal colposcopic findings, cervical intraepithelial neoplasia (CIN) 2 and CIN 3/adenocarcinoma in situ (AIS) were found in 56 patients (16%), and invasive carcinoma was found in four patients (0.1%).

Conclusion: This analysis suggests that ECC is a valuable tool in the diagnosis of cervical intraepithelial neoplasia, especially for patients who present with a normal colposcopy of the cervix and vagina but have either recurrent abnormal cytologic findings or high-grade abnormal cytology indicating CIN 2 + .

Purpose: Same-day discharge (SDD) is increasingly prevalent following minimally invasive hysterectomy (MIH). However, consensus guidelines for selecting SDD eligibility criteria for MIH remain unexplored. This study aims to identify predictive factors for non-SDD following MIH (registered in PROSPERO CRD42022350373).

Methods: PubMed, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials. All original studies that involve patients who were discharged on the same day are compared with those who were not (not failure to discharge / not intended to discharge). Categorical and continuous variables were reported as risk ratios with 95% confidence intervals and weighted mean differences with 95% CIs, respectively. Heterogeneity among the included studies was assessed using the I2 statistics. We conducted sensitivity analysis to identify the reason(s) for this heterogeneity.

Results: Ten studies (59,589 patients) were included, with a mean SDD rate of 20.28%. The predictors of overnight observation included factors such as American Society of Anesthesiologists classification (ASA) > II (P = .02; I² = 92%), increased estimated blood loss (EBL) (P < 0.00001; I² = 87%), surgeries starting later in the day (P < 0.00, I² = 15%), and longer operation times (P = .002; I² = 96%). In sensitivity and subgroup analyses, uterus weight emerged as a potential factor (P < 0.00; I² = 50%), while the results concerning ASA, uterine weight, and EBL appeared to be homogeneous. However, the operation time remained heterogeneous.

Conclusion: These factors could assist surgeons in the decision-making process regarding the performance of SDD subsequent to MIH procedures for patients.

Purpose: Breast cancer is a primary cause of cancer-related death among women worldwide. Neoadjuvant chemotherapy (NACT) is a cornerstone treatment for locally advanced, non-metastatic breast cancer. Achieving pathological complete response (pCR) is often used as a surrogate marker for long-term outcomes. This study examines the impact of obesity, defined by a body mass index (BMI) over 30 kg/m², on achieving pCR in patients with early stage breast cancer (eBC) undergoing NACT.

Methods: A retrospective analysis was conducted on patients with eBC treated with NACT at the University of Tübingen. The primary objective was to assess the impact of obesity on achieving pCR. Logistic regression analysis was used to determine the association between pre-treatment BMI and pCR, adjusting for covariates such as age, tumor stage, grading, and chemotherapy intensity.

Results: The study included 325 patients, with 24% classified as obese. While the univariate logistic regression analysis showed no significant impact of obesity on the odds ratio of achieving pCR, the multivariate analysis, accounting for covariates, demonstrated that obese patients had a significantly higher likelihood of achieving pCR.

Conclusion: In this retrospective study, obesity significantly affected the likelihood of achieving pCR in patients with eBC cancer undergoing NACT after adjusting for covariates. While obesity is a known risk factor for breast cancer development and progression, its impact on the efficacy of NACT in terms of achieving pCR was positive in our study. These findings contribute to the ongoing debate in the literature, though the retrospective design and potential uncontrolled factors should be considered.

Purpose: To compare the characteristics and outcomes of non-surgical and surgical treatments for Cesarean scar pregnancy (CSP).

Methods: A retrospective study conducted at a tertiary university affiliated medical center, including all women diagnosed with Cesarean scar pregnancy between 2019 and 2023. Women treated non-surgically (including: methotrexate, uterine artery embolization and balloon catheter) were compared to women treated surgically (including: hysterectomy, hysteroscopy and excision of the pregnancy with or without uterine niche repair). Demographic information, medical history, obstetric and gynecological characteristics, presenting symptoms, imaging findings, management details, surgical characteristics, and follow-up data were collected from the women's electronic medical records. Primary outcome was defined as the β-hCG levels on follow-up visit at 2 weeks following treatment.

Results: 42 women were diagnosed with Cesarean scar pregnancy during the study period, of them 9 (21%) were treated non-surgically and 33 (79%) were treated surgically. Median age was 33 (30-36) year old and median BMI was 31 (27-35) kg/m², with no statistical differences in-between the groups. Most of the women had previous two Cesarean sections (n = 12, 28%). 63% of the women were asymptomatic at the time of diagnosis. On transvaginal ultrasound examination, embryo was demonstrated in 66.7% and cardiac activity was observed in 75%. The median gestational age at diagnosis and β-hCG levels were comparable between the non-surgical and surgical treatment groups (p = 0.22, p = 0.61, respectively). In the surgical arm, the most common surgical procedure was excision of the pregnancy with uterine niche repair, that was performed in 14/42 (33%) of the women. Median hospitalization length was 3 (1-4) and 2 (1-3) days, for the non-surgical and surgical treatment groups, respectively (p = 0.51). The hemoglobin level before discharge was similar between the groups (p = 0.20). Only one woman in each group visited the emergency room before the follow-up visit (p = 0.31). β-hCG levels on follow-up were significantly lower in the surgical group compared to the non-surgical (p = 0.02).

Conclusions: Cesarean scar pregnancy can be asymptomatic and should be suspected to enable early diagnosis. Both non-surgical and surgical treatments are viable options, with comparable hospitalization lengths; however, the surgical intervention group is expected to show a significantly faster decrease in β-hCG levels.

Introduction: Track and field is a high-impact sport that may facilitate pelvic floor dysfunction (PFD) of females. Although increasing the information may reduce deleterious habits, the traditional workshops to date did not motivate and engage the female athletes. This study aimed to evaluate the effects of an online educational workshop about pelvic floor awareness on knowledge and habits of track and field female athletes.

Methods: A total of 49 track and field athletes participated in this quasi-experimental study: 38 attended an educational workshop and 11 did not. The workshop included innovative resources, such as 3D anatomic models, practical proprioceptive exercises guided by physiotherapists, and an anonymous questions and answers section. Before and 1 month later, all the athletes fulfilled an anonymous questionnaire to assess their knowledge about urinary incontinence (UI), ano-rectal incontinence (ARI), pelvic organ prolapse (POP) and female sexual dysfunction (FSD), as well as toileting and sports habits.

Results: After attending the workshop, athletes obtained higher scores in knowledge about ARI (p = 0.019), POP (p < 0.001), and FSD (p = 0.018) compared to baseline and athletes who did not attend it. No improvements were observed in habits and knowledge about UI (p > 0.05). The athletes who reached 70% of correct responses about POP had greater number of healthy habits than the rest of the athletes.

Conclusions: An innovative educational workshop about pelvic floor increases knowledge of track and field female athletes but is insufficient to modify their habits. Sports and health professionals should design educational strategies to manage the most unknown topics about pelvic floor care, considering that the proposed methodology and innovative resources are effective to increase knowledge.

Purpose: This study aimed to investigate the clinical safety and efficacy of laparoscopic lateral suspension (LLS) with mesh in the treatment of severe anterior and apical pelvic organ prolapse (POP) Chinese women with a 2-year follow-up.

Methods: We conducted an observational cohort study. Sixty patients who presented apical (uterovaginal or vault) and anterior prolapse at stage 3 or higher were enrolled. The LLS surgical procedure was performed in accordance with Dubuisson standard operation. The objective and subjective cures as well as the surgery-related complications were evaluated. The POP-related questionnaires were used to evaluate the quality of life before operation and at 24 months after operation follow-up.

Results: Objective cure rates at 2 years of follow-up were 88.3% for the anterior compartment, 100% for the apical compartment and 93.3% for the posterior compartment. The subjective cure rate reached to 93.3%. There were statistically significant lower scores of the pelvic floor impact questionnaire-7 (PFIQ-7) and the pelvic floor distress inventory-short form-20 (PFDI-20) for all women after surgery and they exhibited similar scores of the pelvic organ prolapsed-urinary incontinence sexual questionnaire-12 (PISQ-12) (P = 0.317). And no significant difference was demonstrated in international consultation on the incontinent questionnaire short form (ICI-Q-SF) (P = 0.551). No major complications associated with LLS were observed in our study.

Conclusion: We consider that LLS with mesh operation is safe, feasible and effective to correct severe apical and anterior POP after 2-year follow-up.

Objective: The aim of our study was to assess the impact of sequential embryo transfer on pregnancy outcomes among patients with recurrent implantation failure (RIF).

Methods: We conducted a comprehensive search across various databases for eligible clinical trials from inception to January 2024. Randomized controlled trials (RCTs) were included if they compared sequential embryo transfer, comprising both cleavage-stage and blastocyst-stage embryos, with other transfer protocols in infertile women with repeated implantation failure. Meta-analysis was performed using Revman software. Our primary focus was on the ongoing pregnancy rate. Our secondary measures included rates of chemical pregnancies, clinical pregnancies, miscarriages, and multiple pregnancies.

Results: Seven RCTs, encompassing 909 patients, met the inclusion criteria. Sequential embryo transfer demonstrated a significant increase in the ongoing pregnancy rate compared to the control group (OR = 2.28, 95% CI [1.46, 3.56], p = 0.003). Moreover, the sequential embryo transfer group exhibited notable improvements in chemical and clinical pregnancy rates. There were no statistically significant differences between the groups regarding multiple pregnancy and miscarriage rates (p > 0.05).

Conclusions: Sequential embryo transfer shows promise in enhancing pregnancy outcomes among RIF patients. However, additional trials are warranted to validate our findings.

Purpose: Distinct clinical phenotypes of pathological fetal heart rate (FHR) tracings may affect neonatal outcomes differently. This study aimed to determine and differentiate neonatal outcomes amongst the clinical phenotypes of pathological FHR tracing.

Methods: This prospective observational study included women in labour with pathological fetal heart rate tracing during delivery. Pathological fetal heart rate tracings were characterized into 11 clinical phenotypes and corresponding neonatal and maternal outcomes were recorded. Neonates and mothers were followed till discharge from the hospital. The primary outcome was a 5-min Apgar score. The secondary outcomes were NICU admission, mode of delivery, mode of anesthesia, neonatal morbidity and mortality.

Result: 271 women with pathological fetal heart rate tracing at the time of delivery were included in the study. Most of the women (64%) underwent cesarean delivery. The most common pathological fetal heart rate tracing was repetitive late decelerations (24.7%), followed by reduced variability with repetitive variable decelerations (24.4%). The 5-min Apgar score was comparable across all clinical phenotypes of pathological fetal heart rate tracing. Tachycardia with reduced variability was associated with a significantly higher likelihood of NICU admission (aOR 5.03, 95% CI 1.32-19.27, p = 0.018). Reduced variability, repetitive late decelerations and the combination of repetitive late decelerations with prolonged decelerations and reduced variability showed moderately increased odds of NICU admission.

Conclusions: The 5-min Apgar score remained comparable in all clinical phenotypes of pathological fetal heart rate tracing. Nonetheless, the odds of NICU admission were significantly higher in women with tachycardia and reduced variability.
