The human liver fluke Opisthorchis viverrini (Ov), the primary risk factor for cholangiocarcinoma (CHCA), is a parasite endemic to southeast Asian countries. With no effective treatments for CHCA currently available, early diagnosis and treatment of Ov infection remains the only practical method for the prevention of CHCA. In this study, plasma phosphoproteomes of patients in the non-Ov infection, non-cholangiocarcinoma subject group (non-OVCCA), the asymptomatic Ov infected group (OV), and the CHCA group (CCA), were investigated to identify potential biomarkers for Ov infection and CHCA. The AKT signalling pathway was found to be up-regulated. Phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit beta isoform (PIK3CB), an upstream signalling molecule, was selected as a potential biomarker and evaluated using indirect enzyme-linked immunosorbent assay (ELISA). Results demonstrated evidence that levels of PIK3CB in both the OV group and CCA group was statistically different compared to the non-OVCCA group (P < 0.01). However, the levels of PIK3CB between the OV group and the CCA group were found not to be statistically different. Sensitivity and specificity for OV using OD450 cut-off at >1.570 was 76 and 72%, respectively. For CCA, sensitivity and specificity using OD450 cut-off at >1.398 was 68 and 76%, respectively. Application of indirect ELISA detecting plasma PIK3CB will be of great benefit for screening of opisthorchiasis and CHCA.

Background/objectives: Most studies on the interaction between the immune system and cancer focus on T-cells, whereas studies on tumor-infiltrating B-lymphocytes (TIL-Bs) are still underrepresented. The aim of this study was to assess the prognostic impact of TIL-Bs in early- and advanced-stage oral cavity squamous cell carcinoma (OCSCC).
Methods: In total, 222 OCSCCs were studied.

Individuals with bipolar disorder (BD) show heterogeneity in clinical, cognitive, and daily functioning characteristics, which challenges accurate diagnostics and optimal treatment. A key goal is to identify brain-based biomarkers that inform patient stratification and serve as treatment targets. The objective of the present study was to apply a data-driven, multivariate approach to quantify the relationship between multimodal imaging features and behavioral phenotypes in BD.

Objective: To explore the application value of MRI-based imaging histology and deep learning model in the identification and classification of breast phyllodes tumors.
Methods: Seventy-seven patients diagnosed as breast phyllodes tumors and fibroadenomas by pathological examination were retrospectively analyzed, and traditional radiomics features, subregion radiomics features, and deep learning features were extracted from MRI images, respectively. The features were screened and modeled using variance selection method, statistical test, random forest importance ranking method, Spearman correlation analysis, least absolute shrinkage and selection operator (LASSO).

Objective: Our paper focuses on the psychosocial risks faced by fishers in Aotearoa New Zealand, a sector with limited existing research on this topic. Using a culture-centered approach (CCA), we aimed to develop "voice infrastructure" to capture and present the voices of fishers, addressing the structural inequalities that can often leave fishers (like other marginalized groups) unheard. This paper focuses on the methodology of our pilot project that used a collaborative effort between academics, fishers, government, and non-government agencies, with the goal of understanding and mitigating the psychosocial risks within the commercial fishing industry.
