(1) Background: Circulating tumor DNA (ctDNA) has emerged as a promising biomarker for many kinds of tumors. However, whether ctDNA could be an accurate diagnostic biomarker in colorectal cancer (CRC) remains to be clarified. The aim of this study was to evaluate the diagnostic accuracy of ctDNA in CRC. (2) Methods: PubMed, Web of Science, and Cochrane databases were searched to identify studies reporting the use of ctDNA to screen and diagnose CRC, and all relevant studies published until October 2022 were enrolled for our analysis. These studies were divided into three primer subgroups: the subgroup of quantitative or qualitative analysis of ctDNA and the subgroup of septin9 (SEPT9) methylation assay. (3) Results: A total of 79 qualified articles with 25,240 subjects were incorporated into our meta-analysis. For quantitative studies, the combined sensitivity (SEN), specificity (SPE), and diagnostic odds ratio (DOR) were 0.723 (95% CI: 0.623–0.803), 0.920 (95% CI: 0.827–0.966), and 23.305 (95% CI: 9.378–57.906), respectively, yielding an AUC of 0.860. The corresponding values for qualitative studies were 0.610 (95% CI: 0.566–0.651), 0.891 (95% CI: 0.878–0.909), 12.569 (95% CI: 9.969–15.848), and 0.823, respectively. Detection of SEPT9 methylation depicted an AUC of 0.879, with an SEN of 0.679 (95% CI: 0.622–0.732), an SPE of 0.903 (95% CI: 0.878–0.923), and a DOR of 20.121 (95% CI:14.404–28.106), respectively. (4) Conclusion: Blood-based ctDNA assay would be a potential novel biomarker for CRC screening and diagnosis. Specifically, quantitative analysis of ctDNA or qualitative analysis of SEPT9 methylation exhibited satisfying diagnostic efficiency. Larger sample studies are needed to further confirm our conclusions and to make the ctDNA approach more sensitive and specific.

Purpose: Venous thromboembolism (VTE) comprises deep venous thrombosis (DVT) and pulmonary embolism (PE), which can lead to death. VTE is an insidious disease with no specific symptoms and overlooked readily. We aimed to establish prediction models for VTE in non-oncological urological inpatients to aid urologists to better identify VTE patients. Patients and Methods: A retrospective analysis of 1453 inpatients was carried out. The risk factors for VTE had been clarified in our previous study. A stepwise regression method was used to screen the relevant influencing factors for VTE and construct a logistic regression prediction model to predict VTE. To validate the accuracy of the model, data from 291 patients from another cohort were used for external validation. Results: A total of 1453 inpatients were enrolled. Five potential risk factors (previous VTE; treatment with anticoagulants or anti-platelet agents before hospital admission; D-dimer ≥ 0.89 μg/mL; lower-extremity swelling; chest symptoms) were selected by multivariable analysis with p < 0.05. These five risk factors were used to build a logistic regression prediction model. When p < 0.1 in the multivariable logistic regression model, two additional risk factors were added: Caprini score ≥ 5 and complications, and all seven risk factors were used to build another prediction model. Internal verification showed the cutoff values, sensitivity, and specificity of the two models to be 0.02474, 0.941, 0.816 (model 1) and 0.03824, 0.941, and 0.820 (model 2), respectively. Both models had good predictive ability, but prediction accuracy was 43.0% for both when using the data of the additional 291 inpatients in the two models. Conclusion: Two novel prediction models were built to predict VTE in non-oncological urological inpatients. This is a new method for VTE screening, and internal validation showed a good performance. External validation results were suboptimal but may provide clues for subsequent VTE screening.

Chronic liver disease (CLD) constitutes a major global health burden, with high morbidity and mortality, limited treatment options for several etiologies, and an urgent need for novel therapeutic targets. Fibroblast growth factor 1 (FGF1) is a unique member of the FGF family capable of binding all four FGFR subtypes, thereby regulating multiple signaling pathways including PI3K/AKT, Ras/MAPK, and PLCγ, which are involved in metabolism, cell survival, proliferation, and tissue repair. Emerging evidence highlights the multifaceted and context-dependent roles of FGF1 in CLD. In drug-induced liver injury (DILI) caused by anti-tuberculosis drugs, acetaminophen, or doxorubicin, FGF1 confers protection by restoring bile acid homeostasis, reducing oxidative stress, inflammation, and apoptosis. In Metabolic dysfunction-associated steatotic liver disease (MASLD), FGF1 ameliorates hepatic steatosis, oxidative injury, and insulin resistance through downregulation of SREBP1, upregulation of PPARα, and activation of Nrf2-mediated antioxidant responses. Conversely, in primary sclerosing cholangitis (PSC), FGF1 aggravates ductular reaction, biliary senescence, and liver fibrosis via upregulation of SASP and TGF-β1, suggesting that inhibition of the FGF1/FGFR axis may be therapeutic. For alcohol-related liver disease (ALD), although direct experimental evidence is lacking, FGF1 is hypothesized to confer protection given its known activities against oxidative stress, lipid dysregulation, and cell death. Despite its promise, the mitogenic potential of FGF1 raises safety concerns; however, N-terminally modified FGF1 analogs (e.g., FGF1Δ) retain metabolic benefits with reduced proliferative activity. Collectively, FGF1 represents a versatile and disease-dependent regulator in CLD, warranting further mechanistic studies, safety evaluations, and development of targeted analogs as a novel therapeutic strategy for difficult-to-treat liver diseases.
