Results of a survey among primary care physicians/internists have been supplemented by a comparison with the literature. Methods: In the period from October 5-20, 2015, a survey was sent to 414 primary care physicians/internists in four German cities (n = 10 were undeliverable). The response rate was 58% (n = 235). 34 original works on MPH abuse worldwide were found in the literature and are used in the analysis of the present data situation. The literature published before November 9, 2015 is considered in this paper. Results: 14% of the doctors who took part in the survey said that they had been asked for MPH prescriptions without any medical indication. The most frequent reason given for the request (42%) was adult attention deficit/hyperactivity disorder (ADHD) not verified by documents. According to the comparison with the literature, university students had a lifetime prevalence of MPH misuse ranging from 0.8% to 16.6% and school children had a misuse rate of 4.0%. In the civilian US population, the misuse rate was 4.2%. Among patients in possession of a current MPH prescription due to a diagnosis, the lifetime prevalence was 29% and among adolescents with suspected alcohol and/or drug problems 20%. Conclusions: MPH misuse is a major problem which has not been studied sufficiently. MPH misuse not only plays a role in the field of psychiatry, but also in other disciplines. Misuse particularly following a therapeutic prescription should be taken into account.展开更多

The use of such medications carries significant risk, including intestinal dysmotility and potential for addiction. However, the rates of narcotic use and misuse in patients with UC have not been studied extensively. Functional gastrointestinal disorders(FGID) are prevalent in patients with UC, and have been shown to increase the risk of narcotic use and misuse in patients with Crohn's disease. We hypothesized that patients with UC and a concurrent diagnosis of FGID would have increased rates of both opioid use and misuse in our patient cohort.AIM To evaluate the prevalence of chronic opioid use and misuse in UC.METHODS A retrospective chart review of UC patients seen at the University of Virginia Digestive Health Center was performed on all patients evaluated between 2006 and 2011. Patient demographics, medical, surgical, and medication histories were obtained from the electronic medical record. Concomitant diagnosis of FGID was also noted at the time. The electronic prescription monitoring program was accessed to obtain prescription opioid filling histories. Prescription opioid misuse was defined as opioid prescriptions filled from four or more prescribers and four or more different pharmacies in a 12-mo period.RESULTS A total of 497 patients with UC were included. Patients with UC and FGID were more likely to be female, but no other demographic variables were associated with FGID. Of the UC patients who had FGID, a greater proportion were found to be using opioids chronically(36% with FGID vs 9% without FGID, P < 0.0001)and were misusing prescription opioids(12.8% vs 1.3%, P < 0.001). Multivariate logistic regression demonstrated a significant association with FGID and chronic opioid use(OR = 4.50; 95%CI: 1.91-10.59) and opioid misuse(OR = 5.19; 95%CI1.04-25.76). Tobacco use(OR 2.53; 95%CI: 1.06-6.08) and anxiety(OR 3.17; 95%CI:1.08-9.26) were other variables associated with an increased risk of chronic narcotic use.CONCLUSION FGID was associated with a 4.5-fold increase in chronic opioid use and a 5-fold increased risk of opioid misuse in this patient cohort with UC.展开更多

Security requirements rely on the interactions among normal system execution (use cases), attacks (misuse cases), and necessary security strategies (mitigation use cases), but previous approaches only use a high-level of abstraction. We use refinement to uncover details of each case and the relationships among them before integrating them. We identify and model “includes” and “extends” relationships within each refined case type, and use a condition-driven process that maintains these relationships as refinement continues. We then systematically identify and model “threatens” and “mitigates” relationships to integrate the cases at a detailed level.展开更多

Initiatives for safe prescribing practices for opioid medications include risk assessment for current and future opioid misuse. A clinical screening tool that can be universally applied to all patient populations is currently not available. Our objective was to provide a brief narrative review on opioid misuse from a Canadian perspective as well as a critical appraisal of the available clinical screening tools for detecting aberrant behaviors associated with opioid misuse. The Drug Abuse Screening Test, Addiction Behaviors Checklist, Diagnosis, Intractability, Risk and Efficacy Inventory, Pain Assessment and Documentation Tool, Prescription Drug Use Questionnaire, Prescription Opioid therapy Questionnaire, Screener and Opioid Assessment for Patients with Pain(SOAPP), Revised SOAPP, Pain Medication Questionnaire, Opioid Risk Tool and Current Opioid Misuse Measure were included in the following review. Overall, a wide variability in quality, sensitivity and specificity was observed between screening tools. There is an overall lack of applicability to diverse patient populations as the majority of screening tools have been validated in pain clinic populations only. To conclude, there is a great need for a validated and convenient aberrant behaviors risk assessment tool that can be applied to a diverse patient population in a clinical setting.展开更多

As a result, the relative study of definite article THE acquisition has been one of the the most significant tasks of second language acquisition all the time. For English majors, the acquisition of definite articles THE runs through the whole process of language learning and application. Learner＇ s version of foreign language, known as interlanguage, is a kind of language that exists between the mother tongue （Chinese） and the target language （English）. Interlanguage is a systematic unit which changes and develops constantly. Since definite article THE has rather complex and frequently altered usage, it is inevitable that there are a throng of misuse and problems for English majors when they are using definite article THE. This paper intends to do a survey focusing on English majors＇ application situation of definite article THE. Through analyzing the common misuse and mistakes appeared when English majors are using definite article THE, this paper aims to summerize the FAQ （frequently asked questions） and causes of those misuses. At the same time, the 100 experimental subjects of this survey are equally and randomly chosen from freshmen and third year students of foreign languages college, OUC （Ocean University of China）. By comparing the experimental results of two different grade English major students, this paper aims to demonstrate the influence of different grades on the mastering of definite articles THE of English majors.展开更多

In addition,technical means should be provided to ensure that digital evidence collected cannot be misused for the purpose of perjury. In this paper,we present a method to ensure both authenticity and non-misuse of data extracted from wireless mobile devices. In the method,the device ID and a timestamp become a part of the original data and the Hash function is used to bind the data together. Encryption is applied to the data,which includes the digital evidence,the device ID and the timestamp. Both symmetric and asymmetric encryption systems are employed in the proposed method where a random session key is used to encrypt the data while the public key of the forensic server is used to encrypt the session key to ensure security and efficiency. With the several security mechanisms that we show are supported or can be implemented in wireless mobile devices such as the Android,we can ensure the authenticity and non-misuse of data evidence in digital forensics.展开更多

Errors made when they are using English verbs are analyzed from the aspect of the similarities and differences between English verbs and Chinese verbs in this thesis. We can conclude that the most obvious cause of the misuse seems to be the interference of the first language （L1）, that is, interlingual errors affect the English output of Chinese students. At last, the author calls for more input of the difference between L1 and L2 in L2 teaching and acquisition so that the same mistakes can be avoided.展开更多
