Objective: This study was performed to investigate the diagnostic accuracy of frozen section (FS) of mucinous borderline ovarian tumors (mBOTs) and the diagnostic value of various risk factors for misdiagnosis.
Methods: Patients with either an FS or permanent pathologic diagnosis of mBOT were included. Optimum cut-off values for serum tumor markers and maximal tumor diameter were determined, and risk factors for underdiagnosis of mucinous malignant ovarian tumors (mMOTs) were evaluated. The sensitivity, specificity, Youden's index, and diagnostic odds ratio of the risk factors were assessed to determine their diagnostic value for mMOTs.
Results: Of 121 included patients, 97 were diagnosed with mBOTs by FS. Relatively abnormal cancer antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) levels; bilateral tumors; and specific pathological features showed significant associations with underdiagnosis of mMOTs in the univariate analysis. The presence of specific pathological features was the only significant risk factor in the multivariate analysis. The CA125, CA19-9, and CEA levels and specific pathological features demonstrated certain diagnostic value in detecting malignant cases among FS-diagnosed mBOTs.
Conclusions: In patients with FS-diagnosed mBOT, significant predictors of malignancy were relatively higher CA125, CA19-9, and CEA levels; bilateral tumors; and tumors with specific pathological features.

Early detection of focal cortical dysplasia (FCD) using brain MRI in young children presenting with drug-resistant epilepsy may facilitate prompt surgical treatment, resulting in better control of seizures and decreased associated cognitive difficulties. Characteristics of FCD described in the literature are predominantly based on MRI findings in a fully myelinated brain; therefore, changes occurring during early brain maturation are not well known. In this case report, we describe distinct MRI features of a FCD visualized best before completion of myelination of the cortex and subcortical white matter.

Background: There is no standardization within hand and upper-extremity surgery regarding which patient-reported outcome measures (PROMs) are collected and reported. This limits the ability to compare or combine cohorts that utilize different PROMs. The aim of this study was to develop a linkage model for the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand) and PROMIS PF CAT (Patient-Reported Outcomes Measurement Information System Physical Function computerized adaptive testing) instruments to allow interconversion between these PROMs in a hand surgery population.

Background: The SARS-CoV-2 virus's frequent mutations have made disease control with vaccines and antiviral drugs difficult; as a result, there is a need for more effective coronavirus drugs. Therefore, detecting the expression of various diagnostic biomarkers, including ncRNA in SARS-CoV2, implies new therapeutic strategies for the disease.
Aim: Our study aimed to measure NEAT-1, miR-374b-5p, and IL6 in the serum of COVID-19 patients, demonstrating the correlation between target genes to explore the possible relationship between them.
CAPE activates AMPK and Foxo3 signaling to induce growth inhibition and ferroptosis in triple-negative breast cancer.

Purpose: Approximately 20% of all breast cancer cases are classified as triple-negative breast cancer (TNBC), which represents the most challenging subtype due to its poor prognosis and high metastatic rate. Caffeic acid phenethyl ester (CAPE), the main component extracted from propolis, has been reported to exhibit anticancer activity across various tumor cell types. This study aimed to investigate the effects and mechanisms of CAPE on TNBC.
