Indirect markers of oocyte quality in patients with ovarian endometriosis undergoing IVF/ICSI: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to evaluate the impact of ovarian endometriomas (OMA) on indirect markers of oocyte quality in patients undergoing IVF, compared with women without anatomical or functional ovarian abnormalities. The search spanned original randomized controlled trials, case-control studies and cohort studies published in MEDLINE, the Cochrane Controlled Trials Register and the ClinicalTrials.gov database up to October 2023. Thirty-one studies were included in the meta-analysis, showing no significant differences in fertilization (OR 1.10, 95% CI 0.94-1.30), blastulation (OR 0.86, 95% CI 0.64-1.14) and cancellation (OR 1.06, 95% CI 0.78-1.44) rates. However, patients with OMA exhibited significantly lower numbers of total and mature (metaphase II) oocytes retrieved (mean difference -1.59, 95% CI -2.25 to -0.94; mean difference -1.86, 95% CI -2.46 to -1.26, respectively), and lower numbers of top-quality embryos (mean difference -0.49, 95% CI -0.92 to -0.06). The Ovarian Sensitivity Index was similar between the groups (mean difference -1.55, 95% CI -3.27 to 0.18). The lack of data published to date prevented meta-analysis on euploidy rate. In conclusion, although the presence of OMA could decrease the oocyte yield in patients undergoing IVF/intracytoplasmic sperm injection, it does not appear to have an adverse impact on oocyte quality.

Outcomes of surgical hysteroscopy: 25 years of observational study.

The aim of this prospective study was to analyse the complications of operative hysteroscopy over the last 25 years and determine whether such complications were related to patient characteristics, surgery type, surgical time or distension-medium balance. Three thousand and sixty-three operative hysteroscopies were performed; 52.7% were polypectomies and 31.5% were myomectomies. Myectomies had the highest incidence of complications, at 14%, followed by septolysis, at 6.9%. The most common complications were mechanical (52%). Myomectomies had seven times higher risk than polypectomies of distension-medium complications (RR 7.5, p<.001) but three times lower risk of mechanical complications (RR 0.32, p<.001). The highest incidence of complications occurred in type I myomas and those larger than 3 cm. If we define fluid-balance complications as only those patients who absorbed more than 1.5 L and developed related symptoms, our overall complication rate, including all mechanical complications, was 5.6%.Impact StatementWhat is already known on this subject? In recent years, the importance of properly preventing and managing hysteroscopic complications has risen in line with the number of diagnostic and operative hysteroscopies performed. Complications in operative hysteroscopy differ between surgery types, patient characteristics and the distending media used.What do the results of this study add? This study provides data from a high number of patients compared to previously published studies on the complications of operative hysteroscopies, and includes a study of the relationship between type of surgery and type of complication.What are the implications of these findings for clinical practice and/or further research? Our study shows the importance of a good preoperative assessment, since the complications of hysteroscopy differ greatly depending on the indication. Thus, within myomectomies, knowing the exact type, size and location of the myoma will allow the surgeon to carefully plan the procedure to avoid complications.

Validación de los criterios ecográficos IOTA en la práctica clínica con marcadores tumorales y patología / Validation of IOTA simple ultrasound rules in clinical practice with tumor markers and pathology / Validation of IOTA simple ultrasound rules in clinical practice with tumor markers and pathology

RESUMEN Objetivos . Correlacionar la ecografía prequirúrgica de las masas anexiales aplicando los criterios IOTA y el diagnóstico anatomopatológico tras intervención quirúrgica. Valorar la utilidad de los marcadores tumorales bioquímicos. Método . Estudio observacional prospectivo en 102 pacientes con diagnóstico ecográfico de tumoración anexial, intervenidas quirúrgicamente entre enero 2017 y febrero 2020. El análisis estadístico se realizó con SPSS 17.0. Las variables categóricas se analizaron mediante pruebas de Fisher y chi-cuadrado, las variables cuantitativas mediante prueba t-student. La concordancia entre la valoración de la ecografía transvaginal mediante criterios IOTA y el resultado anatomopatológico, se estudió con el coeficiente de contingencia y el índice kappa. Resultados . Según criterios IOTA, se clasificó como benignas a 48% de las tumoraciones, como malignas 24,5%, y 27,5% resultaron no clasificables. La anatomía patológica confirmó que 68,1% de las benignas y 72,8% de las malignas fueron correctamente filiadas por la ecografía. La concordancia entre la ecografía transvaginal prequirúrgica y la anatomía patológica fue significativa, con coeficiente de contingencia 0,58, índice kappa 0,47, p <0,05 y con sensibilidad 94,1% y especificidad 92,1%. Los valores de la proteína epididimal humana 4 (HE4) y el antígeno del cáncer 125 (CA 125) tuvieron correlación con la anatomía patológica, también con significación estadística, siendo mayor en las pacientes menopáusicas. Conclusiones . Los criterios IOTA discriminaron de forma satisfactoria las masas benignas de las malignas. La proteína HE4 resultó mejor marcador bioquímico que el CA125.

ABSTRACT Objectives: To determine correlation between preoperative ultrasound evaluation of adnexal masses applying IOTA simple rules and pathology diagnosis. To assess usefulness of biochemical tumor markers in these cases. Methods: A prospective study was performed between January 2017 and February 2020. Patients with suspected ovarian pathology were evaluated using IOTA ultrasound rules and designated as benign or malignant. Findings were correlated with histopathological findings. Collected data was statistically analyzed using the chi-square test and kappa statistical method. Results: During this period, 102 women were eligible for the study. According to IOTA ultrasound criteria, 48% of the adnexal masses were classified as benign, 24.5% malignant and 27.5% were not classifiable. Pathology confirmed 68.1% of benign and 72.8% of malignant tumors were correctly classified by ultrasound. Statistically, the agreement between pre-surgical transvaginal ultrasound and pathology result was significant with contingency coefficient 0.58 and Kappa index 0.47, both with p <0.05 significance. The sensitivity for detection of malignancy with IOTA simple rules was 94.1% and specificity 92.1%. As for biochemical tumor markers, human epididymal protein 4 (HE4) and cancer antigen 125 (CA 125) values had statistically significant correlation with pathology results. Conclusions: IOTA simple rules may be used in clinical practice for diagnosis of ovarian tumors. Human epididymis 4 appeared a better diagnostic tool than CA 125 in discrimination of malignant adnexal masses.

Correlación entre el diagnóstico ecográfico prenatal y posnatal en casos de hidronefrosis fetal / Correlation between prenatal and postnatal ultrasound diagnosis of fetal hydronephrosis

Introduction: Prenatal ultrasound detects fetal anomalies in 1% of pregnancies, about 20-30% of them are urogenital and among them 50% are fetal urinary tract dilatations (UTD). Objective: To establish the correlation between prenatal and postnatal hydronephrosis diagnosis, as well as to analyze the prognosis. Design, patients, interventions and main outcome measure: Retrospective observational study performed by the Prenatal Diagnosis Unit of Parc Taulí Hospital (Sabadell), which included 177 pregnant women with ultrasound diagnosis of UTD between January 2011 and December 2016. We performed a descriptive analysis of the most important ultrasound and perinatal variables. The main outcome measure was the degree of dilatation of UTD. Results: The prevalence of HNF was 1.17%; 82.8% were diagnosed in the second trimester ultrasound; 42.9% of fetal hydronephrosis cases were bilateral and, in 95.6%, the urogenital pathology was not associated with other malformations. Congenital heart disease was the most frequently associated prenatal anomaly (3.3%). Among 93 low-risk hydronephrosis cases diagnosed in the second trimester, 53.8% resolved spontaneously in the third trimester, 30.1% remained stable and 16.1% worsened. Of the 32 cases of moderate-severe UTD diagnosed in the second trimester, only 9.4% improved in the third trimester. Complementary examination was required in 46.9% of the neonates and 14.1% required surgical intervention. Conclusions: Most cases of fetal hydronephrosis were diagnosed by second trimester ultrasound. Mild UTD presents good prognosis as opposed to moderate-severe cases, which usually persist after birth.

Introducción. La ecografía prenatal permite detectar una anomalía significativa en 1% de los embarazos; de ellos, 20 a 30% son genitourinarias y 50% de estas son hidronefrosis fetales (HNF). Objetivo. Establecer una correlación entre el grado de hidronefrosis prenatal y posnatal, así como analizar las implicaciones pronósticas. Diseño, pacientes, intervenciones y variables principales. Estudio observacional retrospectivo realizado por la Unidad de Diagnóstico Prenatal del hospital Parc Taulí de Sabadell, que incluyó un total de 177 gestantes con diagnóstico ecográfico de HNF entre enero de 2011 y diciembre de 2016. Se realizó un análisis descriptivo de las variables ecográficas y perinatales más importantes. La principal variable de estudio fue el grado de dilatación de la HNF. Resultados. La prevalencia de HNF fue 1,17%. El 82,8% de los casos fue diagnosticado en la ecografía del 2º trimestre. En 42,9%, la afectación fue bilateral, y en 95,6% la malformación renal fue aislada. La cardiopatía fue la anomalía congénita asociada con más frecuencia (3,3%). De las 93 hidronefrosis de riesgo bajo diagnosticadas en el 2º trimestre, 53,8% se normalizaron en el 3er trimestre, 30,1% permanecieron estables y 16,1% progresaron. De los 32 casos de HNF moderadas-severas diagnosticadas en el 2º trimestre, solo 9,4% se normalizaron en el 3er trimestre. El 46,9% de los neonatos precisó exploraciones complementarias y 14,1% intervención quirúrgica. Conclusiones. Existe buena correlación de la HNF prenatal y posnatal. La HNF leve presenta buen pronóstico, mientras que la moderada-severa suele persistir posnatalmente.
