ABSTRACT
BACKGROUND: Immune cell signatures have been implicated in cancer progression and response to treatment. However, the causal relationship between immune cell signatures and prostate cancer (PCa) is still unclear. This study aimed to investigate the potential causal associations between immune cell signatures and PCa using Mendelian randomization (MR). METHOD: This study utilized genome-wide association studies (GWAS) summary statistics for PCa and immune cell signatures from publicly available datasets. MR analyses, including IVW, MR-Egger, and weighted median methods, were performed to evaluate the causal associations between immune cell signatures and PCa. Multiple sensitivity analysis methods have been adopted to test the robustness of our results. RESULTS: After FDR correction, our findings suggested that specific immune cell signatures, such as HLA DR on CD33+ HLA DR+ CD14dim (odds ratio [OR] = 1.47, 95% confidence interval [CI] = 1.12-1.92, p = 0.006), HLA DR on CD33+ HLA DR+ CD14- (OR = 1.32, 95% CI = 1.05-1.67, p = 0.018), and HLA DR on monocyte (OR = 1.23, 95% CI = 1.03-1.47, p = 0.021), were significantly associated with PCa. PCa had no statistically significant effect on immunophenotypes. These results remained robust in sensitivity analyses, supporting the validity of the causal associations. CONCLUSIONS: This study provides evidence of a potential causal relationship between certain immune cell signatures and PCa. We observed that immune cell signatures involving HLA DR expression on specific cell types are associated with an increased risk of PCa.

BACKGROUND: Chemotherapy is the primary treatment for patients with advanced gastrointestinal cancer, but it has many adverse reactions, particularly nausea and vomiting. Music therapy can reduce anxiety symptoms, avoid the response to the human body under various stress conditions through psychological adjustment, and improve the adverse reactions of chemotherapy. AIM: To investigate the impact of music therapy on relieving gastrointestinal adverse reactions in chemotherapy for patients with digestive tract cancer by meta-analysis. METHODS: EMBASE, PubMed, OVID, WoS, CNKI, CBM, and VIP database were all used for searching relevant literature, and the efficacy after treatment was combined for analysis and evaluation. RESULTS: This study included seven articles. The results of meta-analysis indicated that music therapy could reduce the nausea symptom score of patients after chemotherapy [mean difference (MD) = -3.15, 95% confidence interval (CI): -4.62 to -1.68, Z = -4.20, P < 0.0001]. Music therapy could reduce the vomiting symptom score of patients after chemotherapy (MD = -2.28, 95%CI: -2.46 to -2.11, Z = -25.15, P < 0.0001). Furthermore, music therapy could minimize the incidence of grade I and above nausea or vomiting in patients after chemotherapy (odds ratio = 0.38, 95%CI: 0.26-0.56, Z = -4.88, P < 0.0001). Meta-regression analysis found that publication year was not a specific factor affecting the combined results. There was no significant publication bias (P > 0.05). CONCLUSION: Music therapy can significantly improve the scores of nausea and vomiting symptoms in patients with digestive system cancer during chemotherapy and reduce the incidence of grade I and above nausea and vomiting after chemotherapy, making it an effective psychological intervention method worthy of clinical promotion.
