Purpose: To analyze endometrial metabolite profiles between patients with endometrial cancer and controls., Methods: Seventeen (17) women with endometrium cancer and 18 controls were enrolled in this study. 1 H HR-MAS (High Resolution-Magic Angle Spinning) NMR (Nuclear Magnetic Resonance) spectroscopy data obtained from endometrial tissue samples of patients with endometrial cancer and control group were analyzed with bioinformatics methods., Results: Principal component analysis (PCA) and the partial least squares discriminant analysis (PLS-DA) score plots obtained with the multivariate statistical analysis of pre-processed spectral data shows a separation between the samples from patients with endometrial cancer and controls. Analysis results suggest that the levels of lactate, glucose, o-phosphoethanolamine, choline, glycerophosphocholine, phosphocholine, leucine, isoleucine, valine, glutamate, glutamine, n-acetyltyrosine, methionine, taurine, alanine, aspartate and phenylalanine are increased in patients with endometrial cancer compared to the controls., Conclusion: The metabolomics signature of patients with endometrial cancer is different from that of benign endometrial tissue., (© 2022.

Purpose: To determine the associations between pre-treatment self-reported stress level, salivary cortisol levels, and clinical pregnancy outcome in couples undergoing assisted reproductive technology treatment (ART)., Study Design: Seventy-five couples (150 patients) undergoing ART treatment were enrolled in this study. Psychological variables were assessed using the Perceived Stress Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory, and Beck Depression Inventory. Salivary cortisol levels were obtained from each couple prior to commencing gonadotropin treatment at several times (upon waking and at 15, 30, and 60 min after waking)., Results: There was no statistically significant association between the self-reported stress levels and the ART treatment outcome in couples. Women with a successful outcome after ART treatment had higher median salivary cortisol levels than women who had an unsuccessful result [24.7 (19.9-63.1) vs. 20.7 (10.4-30.4), respectively]. There was no statistically significant difference in the median salivary cortisol levels of men in relation to ART treatment outcome. Salivary cortisol levels of the couples were not correlated., Conclusions: Women who had higher median salivary cortisol levels in the pre-treatment period had a higher clinical pregnancy rate. This result suggests that moderately increased activity of the hypothalamic-pituitary-adrenal axis during ART treatment might be associated with successful conception.

Objectives: The objective was to determine the value of office hysteroscopy in the diagnosis of endometrial hyperplasia by comparing the patients who had hysteroscopic diagnosis of hyperplasia with the results of histopathologic examinations, and to try to describe the visual criteria., Material and Methods: Two hundred and sixteen premenopausal and 114 postmenopausal patients who were admitted to the endoscopic surgery department between January 2000 and March 2001 were enrolled. Visual diagnoses of endometrial hyperplasia with office hysteroscopy were compared with the histopathological results of the endometrial specimen., Results: Pathology confirmed 50 of the 70 hysteroscopically-diagnosed hyperplasia patients. The positive predictive value of office hysteroscopy was 71.4% and the negative predictive value was 95.4% in the diagnosis of endometrial hyperplasia., Conclusion: The accuracy of hysteroscopic evaluation of the uterine cavity is extremely encouraging. Office hysteroscopy, which has a high diagnostic reliability and minimal discomfort, appears to be an ideal method of diagnosis and follow-up of patients with endometrial hyperplasia.

Objective: The objective was to characterize postmenopausal women with endometrial polyps and to evaluate their significance., Methods: The study population included all consecutive postmenopausal patients with a diagnosis of endometrial polyps. Demographic, medical and gynecological data were assessed with regard to the endometrial histologic findings., Results: Of the 181 eligible patients, 34 had endometrial hyperplasia (4 cases of them had endometrial carcinoma). The 144 patients using hormone replacement therapy had significantly higher rate of endometrial hyperplasia than non-hormone users (p<0.006). No differences were observed among the endometrial histological categories for any of the presenting symptoms and signs, ultrasonographic findings, or medical histories., Conclusion: Postmenopausal endometrial polyps is a common, mostly benign entity. However, the relatively high rate of concomitant endometrial hyperplasia, especially in patients receiving hormone replacement therapy, dictates a thorough histological evaluation in all cases.
