Galectin-3, a β-galactoside-binding lectin involved in inflammation and fibrosis, and presepsin, an established biomarker for bacterial infection and sepsis, have emerged as potential biomarkers for improving diagnostic and prognostic accuracy in autoinflammatory diseases. However, their use in FMF patients is not sufficiently evaluated. This study aims to compare serum galectin-3 and presepsin levels in children with FMF and healthy controls and assess their correlations with conventional acute-phase reactants. <b>Methods:</b> This prospective cross-sectional study included 74 children with confirmed FMF during attack-free periods and 67 age- and gender-matched healthy controls. Clinical and genetic characteristics, complete blood count, C-reactive protein (CRP), serum amyloid-A (SAA), and erythrocyte sedimentation rate (ESR) were recorded. Serum galectin-3 and presepsin levels were measured. Group comparisons and correlation analyses were performed using appropriate statistical tests. <b>Results:</b> Median serum galectin-3 and presepsin was significantly higher in FMF patients than controls (<i>p</i> < 0.001). ESR was significantly higher in FMF patients (<i>p</i> < 0.001), while CRP and SAA showed no significant differences. Correlation analysis revealed a strong positive correlation between galectin-3 and presepsin (r = 0.860, <i>p</i> < 0.001) in FMF patients, with neither correlating with other acute-phase reactants. <b>Conclusions:</b> Galectin-3 and presepsin were found to serve as novel biomarkers reflecting alternative inflammatory pathways in FMF, even during remission. These results, obtained during the attack-free period, indicate the need for further studies to determine the relationship between galectin-3 and presepsin levels and disease activity in FMF.</p>","PeriodicalId":11225,"journal":{"name":"Diagnostics","volume":"15 18","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12468796/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145174097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta-learning offers a promising alternative by enabling models to adapt quickly to new tasks using prior knowledge and only a few labeled examples. This study aims to evaluate the effectiveness of representative meta-learning models for thoracic disease classification in chest X-rays. <b>Methods</b>: We conduct a comparative evaluation of four meta-learning models: Prototypical Networks, Relation Networks, MAML, and FoMAML. First, we assess five backbone architectures (ConvNeXt, DenseNet-121, ResNet-50, MobileNetV2, and ViT) using a Prototypical Network.

Although most frequently diagnosed in premenopausal women, it has also been reported in adolescent girls, where it may present as a rapidly enlarging mass that mimics fibroadenoma or phyllodes tumor. The pathogenesis is thought to be hormonally influenced, particularly by progesterone, with a possible role for estrogen. <b>Case Report:</b> We report the case of a 14-year-old girl who presented with a painless, rapidly growing mass in the left breast, first noticed approximately six months earlier. Clinical examination revealed a mobile lesion about 10 cm in diameter without skin changes, lymphadenopathy, or nipple discharge. Ultrasound and MRI demonstrated a large, well-circumscribed solid tumor (10.4 × 11.2 × 4.2 cm³) displacing normal breast tissue but without infiltration; both were classified as BI-RADS 4. Given the tumor size, diagnostic uncertainty, and potential risk of a non-representative core needle biopsy, a decision was made to proceed with primary radical excision. The mass was completely removed with preservation of the glandular tissue. Histopathology confirmed PASH, described macroscopically as a solid, gray-yellow, encapsulated tumor and microscopically as slit-like spaces lined by spindle cells (CD34+, CD31-). Postoperatively, the breast gradually regained symmetry with the contralateral side, and at 14 months of follow-up, no recurrence was observed. <b>Conclusions:</b> PASH, although benign, may present as a large breast tumor in adolescents and clinically mimic both benign and malignant lesions. Histological evaluation based on an adequately performed biopsy is crucial for accurate diagnosis. Complete excision with capsule preservation is recommended to minimize the risk of recurrence. In adolescents, a watchful waiting approach after surgery may be beneficial, as breast tissue often remodels and regains symmetry spontaneously, reducing the need for reconstructive procedures.
