Combination therapy of Sanjie Zhentong capsules for endometriosis: Impact on hormone regulation and serum expression of FOLR1 and MSLN.

Examining the impact of Sanjie Zhentong capsules on hormone levels and serum expression of folate receptor 1 (FOLR1) and Mesothelin (MSLN) in endometriosis patients. A cohort of 150 endometriosis patients admitted between June 2019 and June 2023 was divided into 2 groups based on Sanjie Zhentong intake, comprising 75 cases each. Comparative analyses encompassed uterine artery hemodynamic parameters, ultrasound (B-mode) findings, Visual Analog Scale scores, traditional Chinese medicine symptom scores, Endometriosis Health Profile-30 scores, and serum levels of FOLR1, MSLN, and sex hormones before and after treatment. Post-treatment, both groups exhibited increased peak systolic velocity compared to pretreatment, with the Sanjie Zhentong group showing a significantly higher increase (P < .05). Moreover, resistance index decreased in both groups post-treatment, with the Sanjie Zhentong group displaying a greater reduction (P < .05). Adnexal mass diameters, endometrial thickness, and uterine volume decreased post-treatment in both groups, with the Sanjie Zhentong group experiencing a more pronounced decrease (P < .05). Serum FOLR1, MSLN, and sex hormone levels also decreased post-treatment in both groups, with the Sanjie Zhentong group exhibiting a more significant decrease (P < .05). Additionally, pain scores, traditional Chinese medicine symptoms, and Endometriosis Health Profile-30 scores decreased post-treatment in both groups, with the Sanjie Zhentong group demonstrating a greater reduction (P < .05). Sanjie Zhentong capsules demonstrate efficacy in regulating sex hormones, reducing serum FOLR1 and MSLN expression, alleviating pain, shrinking adnexal masses, decreasing uterine size, and improving uterine artery blood flow in endometriosis patients.

Prenatal phthalate exposure and pubertal development in 16-year-old daughters: reproductive hormones and number of ovarian follicles.

Is there a possible association between prenatal phthalate exposure and late effects in teenage daughters with respect to reproductive hormone levels, uterine volume, and number of ovarian follicles? Our study showed subtle associations between phthalate metabolite concentrations in maternal serum from pregnancy or cord blood and LH and insulin-like growth factor 1 (IGF-1) levels as well as uterine volume in their daughters 16 years later. Endocrine-disrupting environmental chemicals may adversely affect human reproductive health, and many societies have experienced a trend toward earlier puberty and an increasing prevalence of infertility in young couples. The scientific evidence of adverse effects of foetal exposure to a large range of chemicals, including phthalates, on male reproductive health is growing, but very few studies have explored effects on female reproduction. This follow-up study included 317 teenage daughters who were part of the Copenhagen Mother-Child Cohort, a population-based longitudinal birth cohort of 1210 females born between 1997 and 2002. A total of 317 female participants (median age 16 years) were examined for weight, height, and menstrual pattern. A serum sample was analysed for concentrations of reproductive hormones, and trans-abdominal 3D ultrasonography was performed to obtain the number of ovarian follicles, ovarian and uterine size. Prenatal maternal serum samples were available for 115 females, and cord blood samples were available for 118 females. These were analysed for concentrations of 32 phthalate metabolites. Weighted quantile sum regression was used for modelling associations of combined prenatal phthalate exposure with the reproductive outcomes in post-menarcheal females. In bivariate correlation analyses, negative significant associations were found between several prenatal phthalate metabolite concentrations and serum hormone concentrations (testosterone, 17-OH-progesterone, and IGF-1) as well as number of ovarian follicles in puberty. Positive significant correlations were found between prenatal phthalate exposure and FSH and sex hormone-binding globulin concentrations. Combined analyses of phthalate exposure (weighted quantile sums) showed significant negative associations with IGF-1 concentration and uterine volume as well as a significant positive association with LH concentration. Phthalate metabolites were measured in serum from single prenatal maternal blood samples and cord blood samples. Potential concomitant exposure to other endocrine-disrupting environmental chemicals before or after birth was not controlled for. The study population size was limited. Our results support the need for further research into possible adverse effects of environmental chemicals during foetal development of the female reproductive system. The work was supported by The Center on Endocrine Disruptors (CeHoS) under The Danish Environmental Protection Agency and The Ministry of Environment and Food (grant number: MST-621-00 065).

Efficacy and uterine bleeding patterns in initiating goserelin therapy during different menstrual phases in patients with adenomyosis: a prospective cohortstudy.

We carried out this study to explore the possibility of initiating goserelin therapy during the non-menstrual period in patients diagnosed with adenomyosis. 115 premenopausal adenomyosis patients were enrolled and divided into three groups based on their menstrual cycle phase during the initial outpatient visit: menstrual, follicular, and luteal. Each received a 3.6 mg subcutaneous dose of goserelin monthly for three months. The endpoints encompassed alterations in uterine volume, dysmenorrhea Numerical Rating Scale (NRS) score, CA125 level, hemoglobin (HGB) after a 12-week treatment course, and the occurrence and duration of uterine hemorrhage during the first treatment cycle. Analysis revealed that the timing of goserelin therapy initiation in the menstrual cycle did not significantly impact its effectiveness in reducing uterine size, alleviating pain, lowering CA125 levels, or improving hemoglobin concentrations. However, patients starting treatment during the luteal phase experienced increased uterine bleeding (reference: menstrual period, OR = 4.33, 95% CI 1.23-15.25, p = .023). The results suggested non-inferiority of goserelin therapy initiated during the non-menstrual period, but the uterine bleeding rate was higher in the luteal phase group. Therefore, goserelin treatment for outpatient adenomyosis patients should not be limited to starting during the menstrual period; it can also be initiated outside the menstrual period, providing more convenience for patients as most consultations occur outside the menstrual period. However, the use of goserelin during the luteal phase should be avoided to reduce the risk of exacerbated bleeding, especially in anemic patients with heavy menstrual bleeding. This study highlights the importance of individualizing treatment initiation based on the patient's health profile to optimize therapeutic outcomes and minimize adverse effects. ChiCTR2200059548.

Association Among Surgeon Volume, Surgical Approach, and Uterine Size for Hysterectomy for Benign Indications.

To assess the relationship between surgeon volume and surgical approach for patients undergoing hysterectomy for benign indications among uteri of varying sizes. This was a retrospective cohort study of patients who underwent hysterectomy for benign indications from 2012 to 2021 within the Michigan Surgical Quality Collaborative registry. For each hysterectomy, the relative annual volume of the performing surgeon was assessed by calculating the proportion of hysterectomy cases contributed by the surgeon each calendar year relative to the total number of hysterectomies in the registry for that year. Hysterectomies were stratified into tertiles: those performed by low-volume surgeons, intermediate-volume surgeons, and high-volume surgeons. Uterine size was represented by the uterine specimen weight and categorized to facilitate clinical interpretation. Multivariable logistic regression models were developed incorporating interaction terms for surgeon volume and uterine size to explore potential effect modification. A total of 54,150 hysterectomies were included. Hysterectomies performed by intermediate- and high-volume surgeons were more likely to be performed through a minimally invasive approach compared with those performed by low-volume surgeons (intermediate-volume: adjusted odds ratio [aOR] 1.68, 95% CI, 1.47-1.92; high-volume: aOR 2.14, 95% CI, 1.87-2.46). Moreover, this likelihood increased with increasing uterine weight. For uteri weighing between 1,000 g and 1,999 g, the odds of minimally invasive approach was significantly higher among intermediate-volume surgeons (aOR 3.38, 95% CI, 2.04-5.12) and high-volume (aOR 9.26, 95% CI, 5.64-15.2) surgeons, compared with low-volume surgeons. After including an interaction term for uterine weight and surgeon volume, we identified effect modification of surgeon volume on the relationship between uterine size and choice of minimally invasive surgery. For uteri up to 3,000 g in weight, hysterectomies performed by high-volume surgeons have a higher likelihood of being performed through a minimally invasive approach compared with those performed by low-volume surgeons.

Presurgical treatment of uterine myomas with the GnRH-antagonist relugolix in combination therapy: an observational study.

To evaluate if a preoperative medical treatment with the GnRH-antagonist relugolix in combination therapy in a series of patients with abnormal uterine bleeding associated with uterine myomas may correct the anemia before scheduled surgery for myoma-associated AUB. Thirty-one patients scheduled for surgery underwent a pre-operative three-month course with a daily oral tablet of 40mg relugolix, 1mg estradiol, and 0.5mg norethindrone acetate. Hemoglobin levels, uterine volumes, largest myoma diameter, and VAS score for dysmenorrhea, pelvic pressure and bleeding discomfort, and indication to surgery were evaluated at study enrollment and at the end of therapy. Mean hemoglobin levels increased by 25%, from 9.3 ± 1.1 to 11.6 ± 1.7g/dL after three months (p < 0.001). Uterine volume decreased from 380.7 ± 273.4 mL to 281.7 ± 198.7 mL (p < 0.001), whereas the diameter of the largest myoma decreased from 6.4 ± 2.8cm to 5.5 ± 2.2cm (p < 0.001). Four patients (13%), initially planned for a laparotomy procedure, were converted to a minimally-access procedure, whereas in eight patients (26%) surgery was avoided after medical therapy. Dysmenorrhea score improved from 4.7 ± 3.2 to 0.6 ± 1.1 (p < 0.0001). Pelvic pressure score decreased from 5.9 ± 2.1 to 3.1 ± 2.3 (p < 0.0001), whereas bleeding discomfort decreased from 7.4 ± 3.0 to 0.4 ± 1.6 (p < 0.0001). Preoperative GnRH-antagonist therapy may enhance hemoglobin levels, decrease uterine and myoma size, and alleviate symptoms, potentially enabling safe surgical procedures.

Fetus descent simulation with the active uterine contraction during the vaginal delivery: MRI-based evaluation and uncertainty quantification

Finite element models ranging from single to multiscale models have been widely used to gain valuable insights into the physiological delivery process and associated complication scenarios. However, the fetus descent simulation with the active uterine contraction is still challenging for validation and uncertainty quantification issues. The present study performed a fetus descent simulation using the active uterine contraction. Then, simulation outcomes were evaluated using theoretical and in vivo MRI childbirth data. Moreover, parameter uncertainty and propagation were also performed. A maternal pelvis model was developed. The active uterine contraction was modeled using a transversely isotropic Mooney–Rivlin material. Displacement trajectories were compared between simulation, theoretical and in vivo MRI childbirth data. Monte Carlo (M.C) and Polynomial Chaos Expansion (PCE) methods were applied to quantify uncertain parameters and their propagations. Obtained results showed that fetal descent behavior is consistent with the MRI-based observation as well as the theoretical trajectory (curve of Carus). The head downward vertical displacement ranges from 0 to approximately 47 mm. A reduction of 50% in uterine size was observed during the simulation. Three high-sensitive parameters ( C 1 , C 2 , Ca 0 ) were also identified. Our study suggested that the use of the active uterine contraction is essential for simulating vaginal delivery but the global parameter sensitivity, parameter uncertainty, and outcome evaluation should be carefully performed. As a perspective, the developed approach could be extrapolated for patient-specific modeling and associated delivery complication simulations to identify risks and potential therapeutic solutions.

Accuracy of the Measurement of Uterine Leiomyoma by Transabdominal Ultrasonography.

Introduction Uterine leiomyoma is a benign smooth muscle tumor. It does not necessarily require curative treatment, but if conservative management is chosen, it is important to rule out uterine leiomyosarcoma. When a size increase is observed, one must consider malignancy, and thus objective and cost-effective measurement of uterine size is important, especially for early detection of malignant change. Although MRI imaging is thought to be the gold standard for the diagnosis of uterine leiomyosarcoma, frequent MRI is impractical because of the incidence of uterine leiomyoma and the economic burden in real-world clinical practice. On the other hand, ultrasonography (US) is considered the most useful device in the observation of size changes. So this study aimed to examine the accuracy of the measurement of transabdominal US compared to MRI imaging. Materials and methods This retrospective study included 92 patients withuterine myoma ≥ 50 mm who undertook an MRI within 30 days after the transabdominal US. The longest diameter of the largest myoma (a), the longest diameter perpendicular to a in the sagittal image (b), and the longest diameter perpendicular to a and b in the axial image (c) were measured by US and MRI, and these were used to calculate the volume. Results were analyzed by intraclass correlation coefficient (ICC) 3.1. Results The ICC for the volume and major axis of the largest myoma by US and MRI were 0.87 and 0.90, respectively. The 95% confidence intervals (CI) were 0.82-0.91 and 0.87-0.93, respectively. Both reliability levels ranged from good to excellent. ICC was 0.54 (95%CI 0.15-0.78) in myomas with a volume of >500 cm3, and the concordant rate between US and MRI was poor to good. On the other hand, ICC was 0.82 (95%CI 0.57-0.93) even though all myomas with major axes greater than 120 mm had a volume >500 cm3, and the concordant rate between US and MRI measurements was moderate to excellent. In the evaluation by major axis, ICC was 0.60 (95%CI -0.41-0.95) for myomas larger than 160 mm, indicating a lower concordant rate. Conclusion Transabdominal US is an appropriate modality as well as MRI for follow-up of uterine myoma size if the nodules are 160 mm or smaller. Measurement of the major axis is easier and more useful than volume.

Unique Lessons From the Natural Progression of Rejection in Human Uterine Allografts.

Uterus transplantation (UTx) is a novel treatment for absolute uterine infertility. Acute T cell-mediated rejection (TCMR) can be monitored only through serial cervical biopsies. This study, the first of its kind in human transplantation, evaluated clinical, serological, and pathophysiological manifestations of allograft rejection from immunosuppression withdrawal (ISW) to graft hysterectomy (Hx). Following live birth, immunosuppression was abruptly withdrawn from six living-donor UTx recipients. ISW occurred at a median of 7.4 weeks before graft Hx. Post-ISW signs of rejection included: (1) discoloration of the cervix; (2) increased uterine size compared to day of ISW; (3) serological evidence of eosinophilia and progressive development of donor-specific antibodies (DSA) or child-specific antibodies (CSA); (4) histopathological evidence of TCMR in cervical biopsies preceding the development of antibodies in serum; and (5) C4d deposition in tissue before formation of DSA or CSA in all but two recipients. At graft Hx, endometrial glands were preferentially targeted for destruction over stroma while parametrial arteries displayed variable arteritis and fibrointimal hyperplasia. Recognition of the progression of uterine allograft rejection may be important for other human organ recipients and drive research on modulation of immunosuppression and the paradoxical relationship between adaptive cellular and humoral immunity in natural pregnancies.

Impact of uterine weight on surgical outcomes in robotic hysterectomy: An ambispective analysis.

Robot-assisted surgeries are increasingly used for the treatment of benign gynaecological conditions. However, their impact in cases of significantly enlarged uteruses remains uncertain. This study aims to investigate whether the weight of the uterus influences the surgical results of robotic hysterectomy. Ambispective analysis of 306 cases was performed, of which 265 cases were analysed retrospectively. The outcome measures included total operative time, including docking time, console time and vault closure time, complication rates and quality of life (World Health Organization Quality of Life Brief questionnaire) stratified based on uterine sizes into three groups by every 250 g. Of the 306 cases, 76.47% of cases (n = 234) had uterine weight <250 g, 18.30% of cases (n = 56) had uterine weight between 250 and 500 g, while 5.23% of cases (n = 16) had a weight of uterine specimen >500 g. The total operative time was significantly lower in the <250 g group compared to >500 g (81.92 ± 22.81 vs. 111.88 ± 40.27 min; P = 0.003), contributed primarily by the console time. Although the need for post-operative blood transfusion was higher in the >500 g group, the overall complication rate between the three groups was similar. The three groups had comparable QOL through all four domains. The present study underscores the influence of uterine weight on robotic hysterectomy outcomes, revealing increased operative times and post-operative haemoglobin drop for uteri over 500 g. Despite these challenges, complications were not significantly affected by uterine size.

Effect of dienogest treatment on uterine fibroid volume in patients with endometriosis or adenomyosis complicated by uterine fibroids.

Currently, the use of dienogest in clinical practice has increased significantly, and many studies have focused on its effectiveness and safety in the treatment of endometriosis and adenomyosis; however, the effects of treatment with dienogest on uterine fibroid size in patients with endometriosis or adenomyosis have not been investigated. To explore changes in fibroid size in patients with concomitant uterine fibroids undergoing dienogest treatment for endometriosis or adenomyosis and to evaluate the effectiveness and safety of the drug. The clinical data of patients with uterine fibroids treated with dienogest for endometriosis or adenomyosis at Peking University First Hospital from January 2021 to January 2023 were retrospectively analyzed. The maximum uterine fibroid diameter and volume increased after 3 months, 6 months and 1 year of dienogest treatment compared with those before treatment (P < 0.01). The maximum diameter and volume of the uterine adenomyoma increased after 3 months of dienogest treatment but decreased after 6 months and 1 year of treatment compared with those before treatment, but the difference was not significant (P > 0.05). Endometrial thickness and antigen 125 levels were significantly thinner and decreased, respectively, after dienogest treatment (P < 0.01). Pearson's correlation analysis revealed that the increase in uterine fibroid volume after 3 months of dienogest treatment was positively correlated with the basic uterine fibroid volume (r = 0.792, P < 0.01). Among 64 patients with dysmenorrhea, 63 experienced significant relief of dysmenorrhea after 6 months of treatment with dienogest, and all patients experienced significant relief of dysmenorrhea after 12 months. Patients were able to tolerate the drugs, with an average drug tolerance score of 8.73. The use of dienogest in patients with endometriosis or adenomyosis combined with uterine fibroids can effectively relieve the patient's pain symptoms and significantly reduce the sizes of ovarian endometriotic cysts, but it cannot inhibit uterine fibroid growth.

Evaluation of the effectiveness of surgical treatment using sonographic diagnostics with pyometra in dogs

The relevance of this study lies in the necessity to evaluate the effectiveness of surgical treatment for pyometra in dogs, employing sonographic diagnosis. Pyometra, a common uterine infection in female dogs, can lead to life-threatening complications such as sepsis and kidney damage if left untreated. Ultrasound imaging, a non-invasive and effective diagnostic tool, plays a crucial role in the early detection of pyometra and can identify potential post-operative complications following ovariohysterectomy. This study aimed to identify the ultrasound characteristics of the abdominal cavity in dogs affected by pyometra and to compare the postoperative ultrasound features of the abdominal cavity following ovariohysterectomy over time in a group of animals with and without complications. The primary research method involved a sequential and targeted ultrasound examination of the abdominal cavity in dogs diagnosed with pyometra. Subsequent ultrasound examinations were performed during ovariohysterectomy and at 1, 5, and 10 days postoperatively. It was established that the pathologically altered uterus on ultrasound often exhibited characteristics of an enlarged, distended tubular structure with anechoic or hypoechoic content. Ultrasound examination of affected dogs also demonstrated diagnostic effectiveness in cases of visualising intrauterine fluid, even when the uterine size was within normal limits. The use of ultrasound diagnostics allowed for the timely detection of pyometra at early stages, significantly improving the effectiveness of subsequent treatment. Ovariohysterectomy proved to be the most effective treatment method for dogs with pyometra, promoting the normalisation of vital functions as early as 2-3 days post-surgery, which reduced the risk of recurrence. Dynamic ultrasound examination of the abdominal cavity after surgery ensured timely adjustment of treatment measures and improved prognosis for patients. The established facts have practical significance for veterinarians, which will contribute to improving the quality of pyometra diagnosis in dogs, the effectiveness of their treatment, and reducing mortality

The Outcome of the Laparoscopic Hysterectomy in Al-Yarmouk Teaching Hospital in 2022–2023

Abstract Background: Hysterectomy is a common gynecological procedure used for various benign conditions like abnormal uterine bleeding, uterine prolapse, and fibroids. Different surgical methods, including vaginal, abdominal, laparoscopic, and robotic-assisted approaches, offer unique advantages and disadvantages. Total laparoscopic hysterectomy (TLH), introduced in 1989, offers benefits like smaller incisions, less blood loss, reduced pain, shorter hospital stays, and faster recovery. Objectives: The objective of this study was to evaluate patient outcomes, complications, and satisfaction with laparoscopic hysterectomy surgery. Patients and Methods: This cross-sectional study was conducted in Al-Yarmouk Teaching Hospital in Baghdad, General Surgery Department, from August 2022 to August 2023. Twenty-five patients who underwent laparoscopic hysterectomy for benign conditions were included. Patients were carefully assessed, ruling out malignancies through extensive clinical and radiological examinations, ultimately qualifying for the procedure. Data on patients’ demographics, comorbidities, previous surgical history, uterine size, indication for hysterectomy, type of procedures performed, and postoperative complications were gathered and subjected to analysis. The follow-up duration extended over 3 months, with assessments done on the 3rd day, 10th day, 1st month, and 3rd month postsurgery. Results: The mean age was 51.52 ± 9.47 years. Dysfunctional uterine bleeding was the most common indication (44%), followed by postmenopausal bleeding (32%). Most patients underwent TLH with bilateral salpingo-oophorectomy (BSO) (68%), and the mean operative time was 110 min. Complications were observed in 10 (40%) cases, with common issues being blood transfusion, port-site infection, and bladder injury. Hospitalization lasted 2 days, and postoperative pain reduced gradually over time. Patients who underwent concomitant BSO had significantly higher complications than those with isolated TLH. Postoperative pain levels were comparable between the two groups. Conclusion: Laparoscopic hysterectomy is an effective option for treating benign gynecological conditions, offering benefits like improved postoperative pain control and shorter hospital stays. However, the potential for complications, particularly in cases involving additional procedures, is to be considered.

A National Database Study on Racial Disparities in Route of Hysterectomy with a Surrogate Control for Uterine Size: A Proposed Quality Metric for Benign Indications

Study ObjectiveTo investigate the association between race and route of hysterectomy among patients undergoing hysterectomy for abnormal uterine bleeding in the absence of uterine fibroid disease and excluding malignancy. DesignA cross-sectional cohort study utilizing the Healthcare Cost and Utilization Project Nationwide Inpatient Sample and National Ambulatory Surgical databases to compare abdominal to minimally invasive route of hysterectomy. SettingHospitals and hospital-affiliated ambulatory surgical centers participating in the Healthcare Cost and Utilization Project in 2019 Patients75,838 patients who had undergone hysterectomy for abnormal uterine bleeding excluding uterine fibroids and malignancy. Interventionsn/a Measurements and Main ResultsOf the 75,838 hysterectomies performed for abnormal uterine bleeding in the absence of uterine fibroids and malignancy, 10.1% were performed abdominally and 89.9% minimally invasively. After adjusting for confounders, Black patients were 38% more likely to undergo abdominal hysterectomy compared to White patients (OR 1.38, CI 1.12-1.70 p=0.002). Black race thus is independently associated with open surgery. ConclusionDespite excluding uterine fibroids as a risk factor for an abdominal route of hysterectomy, Black race remained an independent predictor for abdominal versus minimally invasive hysterectomy and Black patients were found to undergo a disproportionately higher rate of abdominal hysterectomy compared to White patients.

Anti-Menopausal Effect of Heat-Killed Bifidobacterium breve HDB7040 via Estrogen Receptor-Selective Modulation in MCF-7 Cells and Ovariectomized Rats.

Menopause is induced by spontaneous ovarian failure and leads to life quality deterioration with various irritating symptoms. Hormonal treatment can alleviate these symptoms, but long-term treatment is closely associated with breast and uterine cancer, and stroke. Therefore, developing alternative therapies with novel anti-menopausal substances and improved safety is needed. In our study, heat-killed Bifidobacterium breve HDB7040 significantly promoted MCF-7 cell proliferation in a dose-dependent manner under estrogen-free conditions, similar to 17β-estradiol. This strain also triggered ESR2 expression, but not ESR1, in MCF-7 cells. Moreover, administrating HDB7040 to ovariectomized (OVX) Sprague-Dawley (SD) female rats reduced estrogen deficiency-induced weight gain, fat mass, blood triglyceride, and total cholesterol levels. It also recovered collapsed trabecular microstructure by improving trabecular morphometric parameters (bone mineral density, bone volume per tissue volume, trabecular number, and trabecular separation) and decreasing blood alkaline phosphatase levels with no significant changes in uterine size and blood estradiol. HDB7040 also significantly regulated the expression of Tff1, Pgr, and Esr2, but not Esr1 in uteri of OVX rats. Heat-killed B. breve HDB7040 exerts an anti-menopausal effect via the specific regulation of ERβ in vitro and in vivo, suggesting its potential as a novel substance for improving and treating menopausal syndrome.

Is prolonged luteal phase a problem in lactating Holstein cows?

In this study, the main objective was to assess if long luteal phases could have other causes than pregnancy losses. We enrolled Holstein dairy cows ≥50 d in milk (DIM) from a commercial herd in Brazil from October 2016 to August 2017. All cows received an estradiol-based synchronization protocol, and, on the day of insemination (d 0), were randomly assigned either an artificial insemination (AI) or a placebo insemination (PBO) in a 3:1 ratio. An ultrasound was used to assess the presence of a CL on d17, 24, and 31, which, combined to the information from patches for the detection of estrus, was used to determine the length of the luteal phase following AI or PBO. Pregnancy was assessed by ultrasound on d 31 and cows that were pregnant were excluded from the analyses. The length of the estrous cycles was categorized as short (<17 d), normal (17-23 d), long (24-30 d), and very long (≥31 d). We compared the proportion of cows in each category between the AI and PBO groups using a cumulative ordinal mixed model. We define prolonged luteal phase as estrous cycles ≥24 d and tested its association with potential risk factors (parity, season, DIM, uterine size and position score, milk production, body condition score, and the presence of a corpus luteum (CL) at enrollment to the synchronization protocol) using mixed logistic regression models. Results are presented as odds ratio (OR) and 95% credible intervals (BCI). Data from 876 inseminations (AI: n = 616, PBO: n = 260) was collected. Overall, 12% of estrous cycles were short, 31% were normal, 19% were long, and 38% were very long. There was no difference in the odds of being in longer estrous cycle categories for the AI compared with the PBO group (OR = 0.92, 95% BCI = 0.76-1.10). Season and presence of a CL at enrollment were associated with prolonged luteal phase. In the AI group, there was a possible effect of early pregnancy losses on the lifespan of the CL, but not the PBO group, which led us to conclude that long and very long estrous cycles were not all caused by the embryonic loss. In fact, the high prevalence of cows with an extended CL lifespan in the present study suggests this could be an under- or miss-reported characteristic of high-producing lactating Holstein cows. This finding may have important repercussions in the understanding of the CL function physiology of lactating Holstein cows.

Factors influencing decision-making for the anesthetic technique in molar pregnancy patients for suction curettage: A retrospective study

Anesthetic techniques for suction curettage in molar pregnancy patients described in the literature can be classed into general anesthesia and regional anesthesia techniques. The aim of the present study was to report the factors influencing the decision-making for the choice of anesthetic technique in molar pregnancy patients who underwent suction curettage at Siriraj Hospital. The reported intraoperative and postoperative complications were also analyzed.A retrospective chart review was conducted among pregnant women diagnosed with molar pregnancy who had underwent suction curettage under anesthesia at Siriraj Hospital between January 2007 to September 2021. Overall, 244 patients were diagnosed with molar pregnancy, with 110 of these included for analysis in this study after consideration of the inclusion and exclusion criteria. Quantitative data of the included patients were analyzed by either unpaired t-test or Mann–Whitney U test, while qualitative data were analyzed by the chi-square test. Logistic regression was used to establish the factors influencing the decision-making for the anesthetic technique.General anesthesia was the most preferred anesthetic technique (77.4%) in the molar pregnancy patients who had underwent suction curettage, followed by regional anesthesia (11.3%) and intravenous sedation (11.3%). General anesthesia was likely to be used in patients with an enlarged uterine size ≥ 16 weeks with an adjusted odds ratio of 11.64 (95% CI 1.08–125.72, p &amp;#60; 0.05). Patients with a larger uterine size were associated with higher beta-hCG levels, resulting in more severe medical complications, such as hyperthyroidism and hyperemesis gravidarum (p &amp;#60; 0.05). Intraoperative complications, such as uterine atony (17.7%), massive hemorrhage (7.3%), and pulmonary edema (4.2%), were confined within patients receiving general anesthesia, but there was no statistical significance. None of the patients had anesthesia-related complications. The reported postoperative serious complications, such as pulmonary edema (4.2%), which required postoperative intubation and transferal to the intensive care unit, were all in the general anesthesia group. Patients with higher co-morbidities were advised by anesthesiologists to receive general anesthesia. However, an enlarged uterine size ≥ 16 weeks was the only factor that had an influence on the decisions of the anesthesiologists to provide general anesthesia.

World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonization Project: V. Physical examination standards in endometriosis research

The World Endometriosis Research Foundation established the Endometriosis Phenome and Biobanking Harmonisation Project (EPHect) to create standardized documentation tools (with common data elements) to facilitate the comparison and combination of data across different research sites and studies. In 2014, 4 data research standards were published: clinician-reported surgical data, patient-reported clinical data, and fluid and tissue biospecimen collection. Our current objective is to create an EPHect standard for the clinician-reported physical examination (EPHect-PE) for research studies. An international consortium involving 26 clinical and academic experts and patient partners from 11 countries representing 25 institutions and organizations. Two virtual workshops, followed by the development of the physical examination standards underwent multiple rounds of iterations and revisions. N/A MAIN OUTCOME MEASURE(S): N/A RESULT(S): The EPHect-PE tool provides standardized assessment of physical examination characteristics and pain phenotyping. Data elements involve examination of back and pelvic girdle; abdomen including allodynia and trigger points; vulva including provoked vestibulodynia; pelvic floor muscle tone and tenderness; tenderness on unidigital pelvic examination; presence of pelvic nodularity; uterine size and mobility; presence of adnexal masses; presence of incisional masses; speculum examination; tenderness and allodynia at an extra-pelvic site (e.g., forearm); and recording of anthropometrics. The EPHect-PE standards will facilitate the standardized documentation of the physical examination, including the assessment and documentation of examination phenotyping of endometriosis-associated pelvic pain.

Defining a Uterine Extraction Score based on a Volume/Access Ratio in Total Hysterectomy: a retrospective cohort study.

Regardless of the technique used, extraction of the uterus is a crucial step in hysterectomy. There is currently no scoring system to predict its feasibility. Our main objective was to determine a predictive score of uterine extraction feasibility to optimise surgical planning of total hysterectomy. As secondary objectives, we examined the correlation between uterine volume predicted by preoperative ultrasound and the final weight of the surgical specimen and analysed the impact of the uterine extraction modality on operative and hospitalisation times. We defined a Uterine Extraction Score (UES) based on the ratio between uterine sizes and vaginal access. This score was retrospectively applied to a cohort of 178 patients who were hysterectomised for benign conditions between January 2019 and December 2022. The UES allows identification of three groups of decreasing feasibility of vaginal extraction, symbolised by traffic light colours: green - vaginal extraction without morcellation, orange -vaginal extraction with morcellation, red - abdominal morcellation by mini-laparotomy or primary laparotomy. The results show that the UES--predicted, and the observed routes of extraction concord in 92% of cases. There is a strong correlation between estimated volume and final uterine weight. Uterine morcellation lengthens the operative time and the hospital stay. The UES seems to be a reliable tool to predict the route of uterine extraction in total hysterectomy. The development of a new scoring system empowers surgeons with decisive information to enhance perioperative outcomes.

Abstract B022: Conversion from minimally invasive surgical approaches to open surgery among endometrial cancer patients in a national cancer patients’ registry

Abstract Endometrial cancer (EC) ranks as the predominant gynecological malignancy in the US. While minimally invasive surgical (MIS) techniques have revolutionized EC management, conversion to laparotomy remains a concern, with reported rates varying widely. Factors influencing this conversion, including patient characteristics and tumor attributes, have not been fully understood. Addressing this gap, our study employs a national registry to analyze patient, tumor, and surgeon-related factors contributing to the transition from MIS to laparotomy in EC cases. Results: 0ur results showed, 3.4% (135/4028) experienced planned MIS-to-open conversion. Demographic disparities were absent between conversion and MIS groups. Conversion was more prevalent in obese (29%) and morbidly obese (37%) patients (P=0.04), linked to prior abdominal surgery (63% vs 52%; P=0.001). Endometrioid EC predominated (59%) in the converted group, with higher non-endometrioid rates (serous carcinoma 16%, clear cell carcinoma 4%, carcinosarcoma 5%, mixed histology 12%; all P&amp;lt;0.01). Advanced FIGO stages were more common in conversions (stage II: 5%, stage III: 25%, stage IV: 9%; all P&amp;lt;0.001). Type II (24%) and type III (5%) hysterectomies were more frequent in conversions (P&amp;lt;0.001). Logistic regression indicated BMI, prior surgery, FIGO stage, histology, and operation type affected conversion (p&amp;lt;0.001), explaining 12.3% of variance. Indications for conversion included uterine size, adhesions, and disease extent. Conclusion: the adoption of minimally invasive surgery (MIS) has become increasingly popular for managing endometrial cancer (EC), attributed to enhanced perioperative outcomes. However, prudent patient selection and surgical planning are imperative to mitigate the risk of unplanned transition to open surgery. Predictive factors for such conversion include uterine size, prior abdominal surgeries, surgical complexity, disease extent, and histologic types. Further prospective research is warranted to validate these findings and identify individuals at conversion risk. Ultimately, a personalized surgical approach, tailored to individual patient attributes, remains pivotal for optimizing outcomes in EC management.
