Objective:To evaluate the differences in presentation (formatting) of adverse drug reaction (ADR) information within drug monographs in commonly used drug information (DI) mobile device applications.Methods:A cross-sectional analysis of ADR formatting of twenty commonly prescribed oral medications within seven DI mobile applications was performed. Databases were assessed for ADR information, including presence of placebo comparisons, severity of ADR, onset of ADR, formatting of ADRs in percentile (quantitative) format or qualitative format, whether references were used to cite information, and whether ADRs are grouped by organ system. Data was collected by two study investigators and discrepancies were resolved via consensus.Results:The seven DI mobile applications varied significantly on every analyzed ADR variable with the exception of ADR onset, which was absent in all databases. Significant differences were found for variables known to impact clinical judgment such as placebo comparisons and qualitative versus quantitative formatting. Placebo comparisons were most common among monographs in Lexicomp (30%) but were absent among monographs within other applications. Quantitative information was commonly used in most databases but was absent in Epocrates. Qualitative formatting was present in all Epocrates and Micromedex applications but absent in the majority of other applications. Substantial variations were also found in severity and grouping information.Conclusion:Substantial variation in ADR formatting exists among the most common DI mobile applications. These differences may translate into alternative interpretations of medical information and thus impact clinical judgment. Health care librarians and clinicians should consider ADR formatting when choosing between DI applications.  相似文献

Nutraceuticals are nutritional medicines which are present in edible food items. Most of them are antioxidants with various other biological properties viz, anti inflammatory, anti atherogenic, anticancer, anti viral, anti aging properties etc. They are as simple as minerals like Se2+ to complex organic molecules such as glycyrrhizin (Ca2+, K+ salts of glycyrrhizic acid). They can prevent as well as cure various diseases. Most of the medical people are not aware of the importance of the nutraceuticals as such matters are not part of their text books. Many still think that vitamins are the major nutritional medicines. Actually other dietary principles like terpenes, carotenes, phytosterols, polyphenols, flavanoids, di and poly sulphides, their sulfoxides and their precursor amino acids are necessary to scavenge free radicals in the body which are reactive oxygen species to protect and maintain the vitamin levels in the body. They down regulate the activities of those enzymes which are increased in diseases and they increase those that remove oxidants and detoxify carcinogens. They are immune boosters too. Recently glucosinolates, non toxic alkaloids, certain proteins and even fiber are included in the list of nutraceuticals.  相似文献

Several governments are actively encouraging their administrations to deliver public services exclusively through digital channels. This strategy consists of putting in place a series of complex and specific actions that bring into play numerous actors, to ensure that users are willing to accept digital channels and that weaker users are not disadvantaged. Although this strategy is being increasingly adopted in various countries, scholars have scarcely begun to explore its logic. This research explores how to define a service delivery strategy that forces users to adopt digital channels. Four in-depth case studies have been conducted on Italian local governments that started delivering their non-educational school services through digital channels alone. We found that a mandatory service delivery strategy is feasible when the starting point is to understand the users' characteristics, skills and behaviours and, as a consequence, whether they perceive the service as complex and/or ambiguous. With this in mind, public organisations can select the proper mix of channels for each category of users and combine their change in approach with behavioural-type interventions, i.e. by creating the right conditions to modify the users' behaviour.  相似文献

The purpose of the study was to evaluate whether using only the semitendinosus as a tripled short graft would affect the electromechanical delay (EMD) of the knee flexors. EMD was evaluated in volunteers (N = 15) after they had undergone surgery for anterior cruciate ligament (ACL) reconstruction where the semitendinosus tendon alone was used as a graft. The results were compared with the intact leg and healthy controls (N = 15). After warming up, each subject performed four maximally explosive isometric contractions on an isokinetic dynamometer. Torques were measured by the dynamometer, while the electrical activity of the semitendinosus and biceps femoris muscles was detected using surface electromyography. EMD was found to be significantly increased (p = 0.001) in patients who had undergone ACL reconstruction compared to the controls. On the contrary, no significant differences (p = 0.235) were found for the biceps femoris muscle between the two groups. Similar results were found when the study group was compared with the intact leg group (p = 0.027 for semitendinosus and p = 0.859 for biceps femoris). Harvesting the semitendinosus tendon increases the EMD for the semitendinosus muscle but does not influence the EMD outcomes for the biceps femoris muscle.  相似文献

Science fairs have been for many years a popular school activity in North America. They are a venue for the popularization of science and consequently an important encouragement for the pursuit of careers in science or engineering. However, little is known about students?? perceived motives for participating in local or national science fairs and about the way in which their involvement mediates their interest in science learning and scientific careers. The present study investigates the motivational factors associated with the high school students?? decision to participate in the 2008 Canada-Wide Science Fair, a thoroughly selected and highly motivated group. Our study examines 5 sources of motivation: (1) interest in science content, (2) sense of self-efficacy, (3) assurance of achievement through rewards or gratifications, (4) the social aspect of participating and (5) working strategies to gain scientific knowledge and methods. The understanding of the anticipated benefits participants seek through their involvement in science fairs may have the potential to help science teachers adapt instruction to appeal to a broader range of students in schools, thus nourishing the emergence of more interest in science.  相似文献

The day-to-day business of being a science or mathematics teacher involves the continuous assessment of students. This, in turn, is an inherently discursive process. The aim of the present study is to examine some of the specific discursive practices through which science and mathematics knowing is jointly produced through classroom interaction. In particular, we examine the coproduced nature of two students’ not knowing—one in an outdoor elementary school science lesson and the other in an elementary school mathematics lesson. Our analysis is based on ideas in discursive psychology and challenges conventional interpretations of students’ academic performance in school science and mathematics.  相似文献

In the present study the efficacies of therapy with insulin, sulphonylurea or insulin + metformin on NIDDM patients are compared. One group which was on a definite dose of insulin therapy, but with uncontrolled diabetes was treated by doubling the insulin dose, a second group whose diabetes was not controlled by glibenclamide was switched over to another sulphonylurea viz; glimepiride and a third group whose diabetes was not controlled by insulin therapy was switched over to a combination therapy with insulin +metformin. After recording their initial blood parameters all the groups were treated as above for 3 months, and the parameters were again determined. The fasting blood sugar and serum lipids of the first group were controlled significantly, but the values were far above normal range. However HDL Cholesterol and atherogenic index were near normal range. In glimepiride treated group, none of the parameters showed any amelioration. In the combined therapy group, control of blood sugar and atherogenic index was more or less the same as for group 1, but hyperlipidemia remained slightly above that of the same. From the findings we can infer that in long term diabetes treatment higher doses of insulin and combined therapy with insulin and metformin may be more beneficial than with low doses of insulin or sulfonyl urea alone  相似文献
