JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2022; 41:2307-2315. [PMID: 34913507 PMCID: PMC9285645 DOI: 10.1002/jum.15917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Revised: 11/07/2021] [Accepted: 11/20/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVES Increased ovarian stromal area (SA), stromal-to-ovarian area ratio (S/A), and echogenicity (SEcho) on ultrasonography have been proposed as diagnostic markers for polycystic ovary syndrome. Although several methods to evaluate the stroma exist, their reproducibility has not been defined which limits clinical utility. This study aimed to determine the interrater reliability and agreement of methods to evaluate SA, S/A, and SEcho. METHODS Five raters tested 3 methods to obtain SA and S/A, and one to obtain SEcho on 30 ovarian cineloops under two imaging conditions, simulating real-time (free-choice) or offline (fixed-frame) imaging. For SA, Method 1 subtracted follicular area from the ovarian area, Method 2 involved outlining the periphery of the stroma, and Method 3 represented a hybrid approach in which central follicles were subtracted from the outlined stroma. SEcho was scored on a subjective 3-tiered scale. Intraclass correlation coefficients (ICCs) and the coefficient of variation were determined for SA and S/A, and Fleiss' kappa agreement statistics (κ) were determined for SEcho. RESULTS Interrater reliability of SA was superior using Method 1 (ICC = 0.558 and ICC = 0.705) versus Method 2 (ICC = 0.522 and ICC = 0.230) or Method 3 (ICC = 0.429 and ICC = 0.305) under free-choice and fixed-frame imaging conditions, respectively. Interrater reliability of S/A was also moderate to poor across methods. SEcho was also not reliably assessed across raters (κ = <0.500). CONCLUSIONS Ultrasonographic assessments of the ovarian stroma were associated with moderate to poor reproducibility. Indirect estimates of the ovarian stroma (Method 1) could be optimized to yield a reproducible approach, clarifying the clinical relevance of the stroma.

The Effect of Oligopin Supplementation on Hormonal and Metabolic Profiles in the Polycystic Ovary Syndrome: A Randomized Controlled Trial. Front Endocrinol (Lausanne) 2020; 11:590392.

Abstract
Background A double blind clinical trial was performed to evaluate whether the polycystic ovary syndrome (PCOS)-specific serum markers and metabolic parameters would change in the women with PCOS during the three-month administration of oligopin. Methods In this double-blind multicenter trial, we randomly assigned 80 PCOS women, based on a 1:1 ratio, to receive oligopin (n= 40) or maltodextrin as placebo (n = 40) for up to 3 months. As PCOS-specific outcomes, we investigated the changes in testosterone, sex hormone binding globulin (SHBG), free androgen index (FAI), dehydroepiandrosterone (DHEA), follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Secondary end points were metabolic (fasting glycaemia, hemoglobin A1c (HbA1c), lipids, insulin resistance (HOMA-IR)), anthropometrics parameters and blood pressure from the baseline to the end of treatment. We investigated serum transaminase, alkaline phosphatase (ALP), creatinine (Cr) and blood urea nitrogen (BUN) levels as hepatic and kidney outcomes, respectively. Results The first participant was enrolled on April 18, 2018, and the last study visit took place on May 14, 2019. PCOS-specific serum parameters did not change during the three-month administration of oligopin (p > 0.05), except for a small increase in the FSH levels (p=0.03). Oligopin neither changed the metabolic profile nor the anthropometric parameters or blood pressure. ALP levels was significantly increased in placebo group, as compared with oligopin (p=0.01). Conclusion Oligopin supplementation does not seem to be exerting a beneficial effect on both hormonal and metabolic parameters in the women with PCOS.

Abstract
During ovarian development stroma from the mesonephros penetrates and expands into the ovarian primordium and thus appears to be involved, at least physically, in the formation of ovigerous cords, follicles and surface epithelium. Cortical stromal development during gestation in bovine fetal ovaries (n=27) was characterised by immunohistochemistry and by mRNA analyses. Stroma was identified by immunostaining of stromal matrix collagen type I and proliferating cells were identified by Ki67 expression. The cortical and medullar volume expanded across gestation, with the rate of cortical expansion slowing over time. During gestation, the proportion of stroma in the cortex and total volume in the cortex significantly increased (P<0.05). The proliferation index and numerical density of proliferating cells in the stroma significantly decreased (P<0.05), whereas the numerical density of cells in the stroma did not change (P>0.05). The expression levels of 12 genes out of 18 examined, including osteoglycin (OGN) and lumican (LUM), were significantly increased later in development (P<0.05) and the expression of many genes was positively correlated with other genes and with gestational age. Thus, the rate of cortical stromal expansion peaked in early gestation due to cell proliferation, whilst late in development expression of extracellular matrix genes increased.
