Background Hypertensive heart disease (HHD) is a major public health issue worldwide. We analyzed the global, regional, and national burden of HHD between the years 1990 and 2019 in relation to age, gender, and socioeconomic factors. Methods The prevalence and death rates, the disability adjusted life-years (DALY), and the corresponding age-standardized rates of HHD were extracted from the Global Burden of Disease study 2019. The epidemiological trends were evaluated by calculating the estimated annual percentage changes (EAPC) of the above variates. Results A total of 19.60 million HHD cases were documented in 2019 compared to 7.82 million in 1990, corresponding to an EAPC of 0.17. Contrarily, the global age-standardized death rate (ASDR) and age-standardized DALYs decreased with respective EAPCs of − 0.74 and − 1.02. HHD mostly occurred in people aged over 65. The disease burden of HHD varied considerably between countries, and univariate linear regression indicated that many socioeconomic variables had significantly negative correlations with age-standardized DALY rate. Conclusion HHD cases have increased over the last three decades; however the mortality rate has declined. Multi-faceted improvements in health, education and income could help to alleviate the disease burden of HHD, specially in some regions with lower socio-demographic index and higher ASDR.
Purpose: Chemotherapy is the clinically recommended treatment for patients with operable metaplastic breast carcinoma (MBC); however, its impact remains controversial. This study investigated the possible role of chemotherapy in the treatment of MBC.Methods: The Surveillance, Epidemiology, and End Results (SEER) database was used to identify the operable MBC patients. The competing risk analysis along with the propensity score matching (PSM) method was performed to evaluate the effect of chemotherapy. Moreover, a competing risk nomogram was built to identify prognosis in patients with MBC.Results: Of the 1137 patients with MBC, 775 received chemotherapy and 362 did not receive chemotherapy. The 5-year cumulative incidence of breast cancer-specific death (BCSD) showed similar outcomes in both the Chemo and No-Chemo groups (21.1 vs. 24.3%, p = 0.57). Chemotherapy showed no apparent association with BCSD (HR, 1.07; 95% CI, 0.72–1.60; p = 0.72), even after subgroup analysis or PSM. Race, tumor size, lymph node status, and radiation were identified as the significant factors for MBC after a penalized variable selection process. In addition, a competing risk nomogram showed relatively good accuracy of prediction with a C-index of 0.766 (95% CI, 0.700–0.824).Conclusion: Our findings demonstrated that chemotherapy did not improve BCSD for operable MBC patients. Thus, it may indicate the need to reduce exposure to the current chemotherapy strategies for patients with resectable MBC. Additionally, some novel treatment strategies are required urgently to identify and target the potential biomarkers.
Background The microRNAs (miRNAs) have been validated as prognostic markers in many cancers. Here, we aimed at developing a miRNA-based signature for predicting the prognosis of esophagus adenocarcinoma (EAC). Methods The RNA-sequencing data set of EAC was downloaded from The Cancer Genome Atlas (TCGA). Eighty-four patients with EAC were classified into a training set and a test set randomly. Using univariate Cox regression analysis and the least absolute shrinkage and selection operator (LASSO), we identified prognostic factors and constructed a prognostic miRNA signature. The accuracy of the signature was evaluated by the receiver operating characteristic (ROC) curve. Result In general, in the training set, six miRNAs (hsa-mir-425, hsa-let-7b, hsa-mir-23a, hsa-mir-3074, hsa-mir-424 and hsa-mir-505) displayed good prognostic power as markers of overall survival for EAC patients. Relative to patients in the low-risk group, those assigned to the high-risk group according to their risk scores of the designed miRNA model displayed reduced overall survival. This 6-miRNA model was validated in test and entire set. The area under curve (AUC) for ROC at 3 years was 0.959, 0.840, and 0.868 in training, test, and entire set, respectively. Molecular functional analysis and pathway enrichment analysis indicated that the target messenger RNAs associated with 6-miRNA signature were closely related to several pathways involved in carcinogenesis, especially cell cycle. Conclusion In summary, a novel 6-miRNA expression-based prognostic signature derived from the EAC data of TCGA was constructed and validated for predicting the prognosis of EAC.
Aim: The purpose of this study was to assess the role of marital status in esophageal adenocarcinoma (EAC). Methods: We identified 8341 EAC patients based on the Surveillance, Epidemiology and End Results database during 2007–2015, of whom 7275 were male and 1066 were female. Temporal trends, competing risk analysis and propensity score matching were performed. Results: There was an upward trend for the rate of unmarried patients in both male and female populations (p < 0.05). Unmarried status represented an independent risk factor for higher cancer-specific death (CSD) in males (hazard ratio: 1.11; 95% CI: 1.04–1.18; p = 0.001) but not in females (hazard ratio: 0.96; 95% CI: 0.81–1.13; p = 0.610). Married EAC patients experienced lower CSD compared with their unmarried counterparts in the male cohort.
