When it develops into severe pancreatitis, its prognosis is poor. Therefore, early assessment of the degree of inflammatory response plays a crucial role in the treatment plan and prognosis of patients. More and more studies have shown that the levels of D-dimer (D-D), angiotensin-2 (Ang-2), phosphate, heparin-binding protein (HBP), retinol-binding protein-4 (RBP4), and osteoblastic protein (OPN) are closely related to the severity of acute pan-creatitis and can be used as effective indicators for early assessment of AP. In this paper, the research progress of the above indicators in assessing the severity of AP is summarized.展开更多

There is research that supports the use of electronic records as a tool to speed documentation;and research that found that it is time consuming. The purpose of this quantitative retrospective before-after project was to measure the impact of using the laboratory value flowsheet within the EHR on documentation time. The research question was: “Does the use of a laboratory value flowsheet in the EHR impact documentation time by primary care providers (PCPs)?” The theoretical framework utilized in this project was the Donabedian Model. The population in this research was the two PCPs in a small primary care clinic in the northwest of Puerto Rico. The sample was composed of all the encounters during the months of October 2019 and December 2019. The data was obtained through data mining and analyzed using SPSS 27. The evaluative outcome of this project is that there is a decrease in documentation time after implementation of the use of the laboratory value flowsheet in the EHR. However, patients per day increase therefore having an impact on the number of patients seen per day/week/month. The implications for clinical practice include the use of templates to improve workflow and documentation as well as decreasing documentation time while also increasing the number of patients seen per day. .展开更多

文摘Cyber Attacks are critical and destructive to all industry sectors.They affect social engineering by allowing unapproved access to a Personal Computer(PC)that breaks the corrupted system and threatens humans.The defense of security requires understanding the nature of Cyber Attacks,so prevention becomes easy and accurate by acquiring sufficient knowledge about various features of Cyber Attacks.Cyber-Security proposes appropriate actions that can handle and block attacks.A phishing attack is one of the cybercrimes in which users follow a link to illegal websites that will persuade them to divulge their private information.One of the online security challenges is the enormous number of daily transactions done via phishing sites.As Cyber-Security have a priority for all organizations,Cyber-Security risks are considered part of an organization’s risk management process.This paper presents a survey of different modern machine-learning approaches that handle phishing problems and detect with high-quality accuracy different phishing attacks.A dataset consisting of more than 11000 websites from the Kaggle dataset was utilized and studying the effect of 30 website features and the resulting class label indicating whether or not it is a phishing website(1 or−1).Furthermore,we determined the confusion matrices of Machine Learning models:Neural Networks(NN),Na飗e Bayes,and Adaboost,and the results indicated that the accuracies achieved were 90.23%,92.97%,and 95.43%,respectively.
文摘Objective: To investigate the influence of integrated Chinese and Western medicine treatment on the quality of life and laboratory indicators of patients with novel coronavirus pneumonia (COVID-19). Methods: A prospective, self-controlled study was conducted to analyze the changes in corresponding laboratory indicators and quality of life in 75 confirmed COVID-19 patients treated with integrated Chinese and Western medicine in our hospital during the early stage, middle stage, recovery period, and two weeks after discharge. The effectiveness and safety of the treatment regimen were evaluated in conjunction with the time for 2019-nCoV nucleic acid conversion, disease progression, and adverse reactions. Results: The PLT levels in the initial stage were significantly lower than those in the recovery period in 75 patients. The CRP levels in the initial stage were significantly lower than those after discharge for 2 weeks. The TBIL, IBTL, and DHIL levels in the initial stage were significantly lower than those in the middle stage. The K+ levels in the initial stage were significantly lower than those in the recovery period and after discharge for 2 weeks. The LYMGH levels in the initial stage were significantly lower than those in the recovery period and after discharge for 2 weeks. The TP and ALB levels in the initial stage were higher than those in the middle stage and the recovery period. The LDH levels, scores of daily activity limitation, scores of respiratory distress symptoms, scores of psychological emotions, CT imaging scores, and positive rate of nucleic acid were significantly lower than those in the recovery period and after discharge for 2 weeks. The AG, CK, CK-MB, and α-HBDH levels in the initial stage were significantly higher than those in the recovery period. However, the AMY level in the initial stage was significantly lower than that in the recovery period and after discharge for 2 weeks (p Conclusion: Integrated Chinese and Western medicine treatment has a significant impact on laboratory indicators such as PLT, LYMGH, CRP, TBIL, IBTL, DHIL, TP, ALB, K+, AG, LDH, CK, CK-MB, α-HBDH, AMY, CT imaging, and 2019-nCoV nucleic acid in COVID-19 patients. It has good clinical efficacy and safety, and can improve the quality of life of patients.
