Article Synopsis
- - This study evaluated the effectiveness of three diagnostic tools—Risk of Ovarian Malignancy Algorithm (ROMA), Copenhagen Index (CPH-I), and Ovarian Adnexal Reporting and Data System (O-RADS)—for predicting ovarian cancer in patients with ovarian tumors.
- - Conducted on 462 patients between May 2020 and December 2022, the research found that O-RADS combined with cancer markers like CA125 provided the most accurate predictions, demonstrating high sensitivity and specificity.
- - The results indicated that while all models showed good predictive values, the combination of O-RADS with CA125 yielded the highest predictive accuracy for ovarian cancer detection.
The dielectric properties, tunability and figure-of-merit () of relaxor PbLa(ZrTi)O (PLZT) films have been investigated. Dielectric measurements indicated that the dielectric constant (at zero-bias field), tunability and are enhanced as the film thickness increases, which are mainly attributed to the presence of an interfacial layer near the film-electrode interface. Experimental results illustrated that a slight reduction is observed in both dielectric constant and tunability (-2%) in a wide-frequency range (10 kHz-1 MHz); meanwhile, the value decreases significantly (-17%) with increasing frequency, arising from the higher dielectric loss value.

Methods: In a prospective cohort study, data were collected from 475 patients with ovarian masses diagnosed by gynecologic examination / ultrasound who were hospitalized at the Departments of Obstetrics and Gynecology, Hue University of Medicine and Pharmacy Hospital and Hue Central Hospital, Vietnam, between January 2018 and June 2020. ROMA and CPH-I were calculated based on measurements of serum carbohydrate antigen (CA-125) and human epididymis protein (HE4).
