Analysis of influencing factors of severity in acute pancreatitis using big data mining

SUMMARY OBJECTIVES To evaluate the epidemiological characteristics of acute pancreatitis (AP) and explore potential relationships between these factors and severity. METHODOLOGY Data-sets of 5,659 patients with AP from health statistics and the Information Center of Jiangsu province, between 2014 and 2016, were analyzed. A self-organizing map (SOM) neural network was used for data clustering. RESULTS Biliary acute pancreatitis (BAP) (86.7%) was the most frequent etiological factor. A total of 804 (14.2%) patients had severe acute pancreatitis (SAP). The mean age of patients was 53.7 + 17.3 (range 12~94y). Most of the AP patients were married (75.4%); 6% of mild /moderately severe AP (MAP/MASP) patients were unmarried, which was less than SAP patients (P=0.016). AP patients with blood type AB in the general population (8.8%) was significantly lower than that of AP cases (13.9%) (P=0.019) and SAP cases(18.7%) (P=0.007). The number of AP patients in southern Jiangsu was much higher than that in northern Jiangsu province, especially in Nanjing (1229, 21.7%). The proportion of acute alcoholic pancreatitis (AAP) in the north of Jiangsu (Xuzhou 18.4%) was much higher than that in southern Jiangsu (Suzhou 2.6%). The whole sample was divided into five classes by SOM neural network. If BAP patients were male, old, divorced, and blood type AB or B, they were more likely to develop SAP. Middle-age, unmarried or divorced male patients with blood type B/AB who suffered from HAP or AAP were also more likely to develop SAP. CONCLUSIONS The number of unmarried patients with MAP/MASP was smaller than that of SAP. Blood types AB and B were more frequent in AP, especially in SAP. The differences between southern Jiangsu and northern Jiangsu, in number of AP patients and the proportion of AAP, were significant. In class I and class IV, the ratio of SAP was much higher than in other classes and the whole sample.

Evaluation of Right Ventricular Global Longitudinal Function in Patients with Tetralogy of Fallot by Two-dimensional Ultrasound Speckle Tracking Imaging / 华中科技大学学报（医学）（英德文版）

Quantification of right ventricular(RV)volume and function remains a challenge because of RV complex geometry by conventional echocardiography.The purpose of this study was to assess RV global longitudinal function in patients with tetralogy of Fallot(TOF)by 2-dimensional ultrasound speckle tracking imaging(STI).Thirty-eight patients with TOF were enrolled in this study and divided into child group(n=25)and adult group(n=13)according to age.Thirty-eight age-and sex-matched normal subjects were selected as control groups including child control group(n=25)and adult control group(n=13).RV global longitudinal peak systolic strain(GLS),strain rate(GLSPs),early diastolic strain rate(GLSRe)and late diastolic strain rate(GLSRa)were measured in all subjects by STI from the apical 4-chamber view and compared between groups.Furthermore,the main factors affecting the RV global longitudinal functional parameters were assessed.Compared with those in controls,RV GLS,GLSRs and GLSPe were significantly reduced in patients with TOF(P<0.05 for all).RV GLSRs was significantly decreased in adult patients with TOF as compared with that in child patients(P<0.05).There was no significant difference in RV GLS,GLSRe and GLSRa between child and adult TOF groups(P>0.05).The diameter of right ventricle,main pulmonary artery and ventricular septum defect had correlations with RV GLSRs(r1=-0.490,r2=0.580,r3=-0.528,respectively,P<0.05 for all).Tricuspid annular plane peak systolic velocity(Sm)was the independent predictor of RV global strain and strain rate(β1=0.355,P1=0.031,β2=0.307,P2=0.021).RV global longitudinal function is decreased in patients with TOF,especially in adult patients.STI is a sensitive and accurate technique in RV global functional assessment.
