ObjectiveTo summarize and analyze the etiologies of recurrent acute pancreatitis (RAP) and then conclude the prevention and treatment strategies.MethodSearching relevant literatures of PubMed, CNKI, Wanfang data and other databases in recent years, the etiologies of RAP were analysed and reviewed, then the prevention and treatment strategies were developed.ResultsThe causes of RAP included abnormal function and structure of biliopancreatic duct, metabolic factors, bad living habits, genetic factors and so on. Then based on etiologies of RAP, prevention and treatment strategies of it were summarized.ConclusionsWith the developments of related researches and clinical diagnosis and treatment technologies, the etiologies of RAP are gradually revealed. It is of great significance to clarify the etiologies of RAP and make prevention and treatment strategies for reducing the recurrence of acute pancreatitis.
ObjectiveThyroid nodules are an exceptionally common thyroid disorder. Past studies suggested a possible link between thyroid diseases and breast neoplasms. However, few studies have delved into the causal relationship between thyroid nodules and breast neoplasms. This study conducted a Mendelian randomization (MR) analysis to further investigate the causal relationship between them. MethodsThis study was conducted using data sourced from genome-wide association study (GWAS) summary datasets. The study focused on thyroid nodules, benign breast tumors, and malignant breast cancers as the research objects, and relevant single nucleotide polymorphisms (SNPs) were selected as instrumental variables (IVs). The inverse-variance weighted (IVW) was primarily used to assess the causal relationship between thyroid nodules and breast neoplasms. Cochran’s Q test was employed to detect heterogeneity, while MR-Egger intercept and MR-PRESSO were used to test for pleiotropy. Sensitivity analysis was conducted using the leave-one-out method. ResultsThere was a significant causal relationship between thyroid nodules and malignant neoplasm of breast (OR=0.88, 95%CI 0.83 to 0.95, P<0.01), with no evidence of reverse causality between them (OR=1.01, 95%CI 0.99 to 1.03, P=0.16). No causal relationship was found between thyroid nodules and benign neoplasm of breast, as indicated by both forward MR analysis (OR=0.97, 95%CI 0.89 to 1.06, P=0.51) and reverse MR analysis (OR=0.97, 95%CI 0.92 to 1.04, P=0.40). Sensitivity analyses suggested that the study findings were accurate and reliable. ConclusionThe present study identifies thyroid nodules as a potential protective factor for malignant neoplasm of breast.
