RESUMO
RATIONALE: Ovarian pregnancy is a rare form of ectopic pregnancy, accounting for 0.5% to 3% of the total number of ectopic pregnancies. Its diagnostic rate is very low and it can be easily misdiagnosed before laparoscopy, due to the clinical presentation being very similar to tubal pregnancy. The ovarian blood supply is abundant, and in case of rupture of ovarian pregnancy, intra-abdominal hemorrhage or even hemorrhagic shock may occur, endangering the patient's life. We report a case of ruptured primary ovarian pregnancy through natural conception. PATIENT CONCERNS: This patient had a history of menopause with lower abdominal pain and tenderness. Ultrasound showed a thick-walled cystic echo in the left adnexal region, a dark area of fluid in the pelvis, and an irregular, slightly strong echo posterior to the uterus. Unclotted blood was punctured from the posterior fornix, and her hemoglobin was decreasing with a serum ß-human chorionic gonadotropin of 1800.00 mIU/mL. DIAGNOSES: Through early recognition of clinical manifestations, ultrasonography, laparoscopic exploration, and the final histopathologic examination, this patient was diagnosed with an ovarian pregnancy. INTERVENTIONS: Then, removal of the left ovarian pregnancy lesion was performed, which was visible as villi. And Methotrexate 50 mg was administered locally. OUTCOMES: Through conservative surgical treatment, she recovered well and was discharged with a satisfactory follow-up. LESSONS: Gynecologists should be alert to patients with menopausal lower abdominal pain with or without vaginal bleeding and consider ectopic pregnancy in rare sites, such as ovarian pregnancy. Surgery is the mainstay of treatment, and early laparoscopic exploration may be beneficial in clarifying the diagnosis and performing the concurrent surgical treatment.

BACKGROUND: Endometriosis, a complex gynecological condition, involves inflammation and immune dysregulation. The vaginal microbiota, characterized by its diversity, is an integral part of the vaginal microecology-interacting with vaginal anatomy, the endocrine system, and local mucosal immunity. Imbalances in this microecology are known to precipitate various inflammatory diseases. Despite extensive research, the connection between vaginal microbiota dysbiosis and endometriosis remains a subject of debate. Our study assesses the association between vaginal microecology dysbiosis and endometriosis. METHODS: We systematically searched major electronic databases in English, including Embase, PubMed, The Cochrane Library, MEDLINE (Ovid), BIOSIS (Ovid), China National Knowledge Infrastructure (CNKI), and Wanfang, up to August 15, 2023. Selected articles underwent screening based on predefined inclusion and exclusion criteria. Normal vaginal microecology was defined as a negative Amsel/Spiegel test or Nugent score of 0-3, or Lactobacillus predominance determined by 16S rRNA gene amplification sequencing. Deviations from this norm were classified as dysbiosis, further categorized into bacterial vaginosis (BV) and intermediate BV. Data analysis utilized Revman 5.4, with effect sizes presented as Odds Ratios (OR) and 95% Confidence Intervals (CI). RESULTS: Out of 1081 articles, eight met the inclusion criteria. Utilizing fixed-effect models due to low heterogeneity, the analysis revealed a positive association between dysbiosis and endometriosis (OR = 1.17, 95% CI 0.81-1.70; I2 = 0%), but showed a slight negative association between normal vaginal microecology with endometriosis (OR = 0.90, 95% CI 0.55-1.46; I2 = 29%). However, the association was not significant. Subgroup and sensitivity analyses corroborated the stability of these associations. CONCLUSION: A positive correlation exists between vaginal microecology dysbiosis and endometriosis, notably with intermediate BV. However, the mechanisms underpinning this relationship remain elusive, highlighting the need for further research to overcome limitations. TRIAL REGISTRATION: Registration number: CRD42023445163.

RATIONALE: Uterine adenomyomas (UAs) are common benign tumors, usually not exceeding 280 g or the weight of the uterus at 12 weeks gestation. Postmenopausal giant UAs of diameter larger than 20 cm are rare, as well as steatosis, but curable by surgical excision. Few cases of postmenopausal giant UAs have been reported. PATIENT CONCERNS: Herein, we report a case of a 70-year-old female patient who presented with a giant pelvic tumor of about 20 cmâ ×â 18 cmâ ×â 20 cm with postmenopausal vaginal bleeding, and whose radiographic manifestations did not exclude the possibility of uterine malignancy. DIAGNOSES: Histopathology confirms an adenomyoma with partial adipose metaplasia. INTERVENTIONS: We did an open laparotomy of hysterectomy, bi-adnexectomy, and pelvic adhesion release for the patient. OUTCOMES: Pathology revealed adenomyoma with adipose metaplasia. The patient recovered well and was discharged on postoperative day 7 with satisfactory follow-up.

BACKGROUND: Endometriosis frequently results in pain and infertility. While conservative surgery offers some relief, it often falls short of ensuring satisfactory pregnancy outcomes. Adjuvant GnRH-a is administered post-surgery to mitigate recurrence; however, its impact on pregnancy outcomes remains debated. This study endeavors to assess the efficacy of adjuvant GnRH-a in enhancing pregnancy outcomes post-conservative surgery in endometriosis patients. METHODS: Databases including PubMed, Embase, the Cochrane Library, Medline (Ovid), Web of Science, and Scopus were rigorously searched up to 02 August 2023, without linguistic constraints. Identified articles were screened using strict inclusion and exclusion criteria. Evaluated outcomes encompassed pregnancy rate, live birth rate, miscarriage rate, ectopic pregnancy rate, multiple pregnancy rate, mean postoperative pregnancy interval, recurrence rate, and adverse reaction rate. The Cochrane risk of bias tool and the Jadad score evaluated the included studies' quality. Subgroup and sensitivity analysis were implemented to analyze the pooled results. A meta-analysis model expressed results as standardized mean difference (SMD) and Risk ratio (RR). RESULTS: A total of 17 studies about 2485 patients were assimilated. Meta-analysis revealed that post-surgery, the GnRH-a cohort experienced a marginally elevated pregnancy rate (RR = 1.20, 95% CI = 1.02-1.41; P = 0.03) and a reduced mean time to conceive (RR = -1.17, 95% CI = -1.70- -0.64; P < 0.0001). Contrarily, other evaluated outcomes did not exhibit notable statistical differences. CONCLUSIONS: Incorporating adjuvant GnRH-a following conservative surgery may be deemed beneficial for women with endometriosis, especially before Assisted Reproductive Technology (ART). Nonetheless, owing to pronounced heterogeneity, subsequent research is warranted to substantiate these potential advantages conclusively. REGISTRATION NUMBER: CRD42023448280.

As an important component of urban green spaces, greenhouse gas uptake or emissions from urban lawns cannot be ignored. However, studies of greenhouse gas fluxes from subtropical urban lawns are relatively sparse. The static chamber-gas chromatography method was applied to monitor the ground-air exchange fluxes of various greenhouse gases(CO2, CH4, N2O, and CO) in typical urban lawns of Hangzhou City. Our results showed that the average fluxes had significant seasonal cycles but ambiguous diurnal variations. The grassland and the soil(naked soil without vegetation coverage) acted as sources of atmospheric N2O, with the average fluxes of (0.66±0.17) and (0.58±0.20) µg·(m2·min)-1 for N2O, respectively; however, they were also sinks of CH4 and CO, with the average fluxes of (-0.21±0.078) and (-0.26±0.10) µg·(m2·min)-1 for CH4 and (-6.36±1.28) and (-6.55±1.69) µg·(m2·min)-1 for CO, respectively. The average CO2emission fluxes of urban grassland and soil were(5.28±0.75) and (4.83±0.91) mg·(m2·min)-1, respectively. The correlation analysis indicated that the CO2 and N2O fluxes of grassland and soil were negatively correlated with precipitation, whereas the CH4 and CO fluxes were positively correlated with it. There was no significant correlation between grassland CH4 fluxes and soil temperature, and N2O fluxes had a significant negative correlation with soil temperature; the other greenhouse gas fluxes showed a significant positive correlation with soil temperature. In addition, the seasonal variation in CO2 (R2=0.371 and 0.314) and N2O(R2=0.371 and 0.284) fluxes from both grassland and soil was affected by precipitation, whereas CO fluxes (R2=0.290 and 0.234) were mainly driven by soil temperature compared with the other greenhouse gases.
