Hypertension and its related complications could be a major threat issue for cardiopathy and stroke. Effective prevention and control can decrease the incidence rate of complications in hypertension. Based on the medical data of 3062 patients with cardiovascular and cerebrovascular diseases from 2017 to 2018 in a grade-A tertiary hospital in Shanghai, the study identified the risk factors of hypertension complications by text mining. On this basis, the K2 algorithm based on the improved particle swarm optimization was proposed to optimize the structure of the Bayesian network (BN) by establishing a multi-population cooperative search mechanism. Then the optimized BN was used to analyze and predict the incidence rate of hypertension complications. Results indicate that the major indicators of accuracy, sensitivity, specificity, and AUC have been improved, and the proposed algorithm is superior to the common data mining algorithms such as the back propagation neural network and the decision tree. Through the proposed model and algorithm, the high-risk factors were identified and the occurrence probability of hypertension complications was predicted, which could provide the personalized health management guidance for hypertensive patients to prevent and control hypertension complications.
Although existing literature has well-examined basic weapon carrying trends for juveniles, little is known about weapon carriers’ differential experiences with serious sanctions including suspension, expulsion, or juvenile adjudication. It is unknown what types of weapon carriers are more likely to be subject to these sanctions or the effect of these sanctions on future behavior. The present study addresses these gaps in the literature using data obtained from the National Longitudinal Study of Adolescent to Adult Health. Results indicate that seriously sanctioned weapon carriers are associated with a delinquent and risky lifestyle while other weapon carriers largely avoid these problem behaviors. Both groups, however, bring weapons to school equally often. Findings indicate that weapon carriers with gang membership are less likely to carry weapons to school or work in adulthood or own a handgun in adulthood if they avoid serious sanctioning. Policy implications of these findings are discussed. 相似文献
