University libraries are questioning the added value of open shelves with books. As scientific publications are increasingly available in electronic format, which role do bookshelves have in the future library space? The Utrecht University Library case study invites librarians to fundamentally rethink how they could strengthen the function of open shelves in their library. Based on acquisition and user data, and on interviews with publishers and users, this article suggests that in 2025 bookshelves could play an important role in providing access to those publications which are preferred by users in paper format. However, bookshelves should no longer focus solely on paper publications, but on digital publications too, as most library collections increasingly become hybrid. Moreover, libraries should also think of ways to enhance the inspiring role of bookshelves. Then, the open shelves could have added value within the library space of the future, providing access to a hybrid collection and an inspiring place to study. 相似文献

This case report describes false shortening of activated partial thromboplastin time (aPTT) due to erroneous optical reading of the clotting point in the presence of unfractionated heparin (UFH), and a biphasic waveform. Activated partial thromboplastin time performed on a coagulometer with photo-optical detection yielded an ambiguous clotting curve characterized by an early and steady decrease in light transmittance throughout the whole measuring range, with the clotting point read at 65 seconds. Further investigations included measurement of aPTT by means of a mechanical clot detection method as well as determination of another heparin-sensitive coagulation assay, that is thrombin time (TT), both being unmeasurably prolonged (> 150 seconds). Communication with clinicians revealed that the patient was on continuous UFH therapy and had an underlying sepsis, with highly elevated C-reactive protein (289 mg/L). The aPTT measurements requested at three timepoints later during the same day revealed gradual aPTT shortening and unveiled a peculiar biphasic waveform pattern. In this case, unmeasurably prolonged aPTT due to UFH therapy was masked by a biphasic aPTT curve pattern making only the first slope of the biphasic waveform visible within the measuring range. The early decrease in plasma light transmittance mimicked optical changes related to clot formation, thus causing erroneous optical reading and yielding a falsely shortened aPTT. This case emphasizes that such a pattern should be carefully inspected, especially when a combination of a critically ill condition and UFH therapy is present, in order to prevent erroneous reporting of aPTT and potential adverse effects on patient care. 相似文献

College students' tobacco use poses a significant public health problem. Effective intervention requires understanding of this behavior among race/ethnic, cultural, and linguistic collegiate subgroups, including deaf and hard of hearing collegians. Findings from a first-ever tobacco-related survey among this understudied population are reported. The authors used written questionnaires and the Interactive Video Questionnaire, a multimedia computer technology developed for use with the deaf and hard of hearing, to interview 241 volunteers on seven California college campuses. They found lower self-reported current smoking prevalence (14.5%) relative to collegians in the general population, but considerable ever smoking (65.1%) and multiple types of tobacco use (37.3%). The authors report on factors associated with tobacco use and on students' exposure to cigarette marketing, gaps experienced in receipt of antitobacco messages and services, and students' antitobacco intervention recommendations. Limitations of the research are described, including possible underreporting of participants' tobacco use. 相似文献

IntroductionActivated partial thromboplastin time (aPTT) is determined and reported as clotting time in seconds aPTT(s), but it is presumed that reporting results as patient-to-normal clotting time ratio, aPTT(r), could minimize within-laboratory variability. The aim of study was to investigate differences in reporting aPTT results that can affect comparability of the results among Croatian laboratories and suggest further steps for its harmonization.Materials and methodsThe questionnaire on aPTT reporting practice was distributed to 83 laboratories through Survey Monkey application in March 2019 as the part of the first regular round of Croatian Centre for Quality Assessment in Laboratory Medicine proficiency testing.ResultsThe survey response rate was 0.49. Majority of laboratories report aPTT results as both, seconds and ratio. Participants reported use of 23 different aPTT(s) reference intervals along with 17 different combinations of reagent/coagulometer and 25 aPTT(s) denominators of different origin for aPTT(r) calculation. Despite the same aPTT(s) results, the use of different denominators caused a dispersion of aPTT(r) results that can lead to exceeding external quality assessment performance criteria of 7%, particularly when results were compared for the same reagent group only. By applying aPTT(s) reference interval mean as denominator for calculation of aPTT(r) reference interval better concordance to harmonized one was obtained (17 vs. 27; χ2 = 3.972; P = 0.046).ConclusionIn order to improve comparability of the results, laboratories are advised to use mean of aPTT(s) reference interval as denominator for aPTT(r) calculation. Type of coagulometer need to be considered when evaluating aPTT proficiency test results and its currently acceptable limit of performance evaluated accordingly. 相似文献

Dynamic sitting, such as fidgeting and desk work, might be associated with health, but remains difficult to identify out of accelerometry data. We examined, in a laboratory study, whether dynamic sitting can be identified out of triaxial activity counts. Among 18 participants (56% men, 27.3 ± 6.5 years), up to 236 counts per minute were recorded in the anteroposterior and mediolateral axes during dynamic sitting using a hip-worn accelerometer. Subsequently, we examined in 621 participants (38% men, 80.0 ± 4.7 years) from the AGES-Reykjavik Study whether dynamic sitting was associated with cardio-metabolic health. Compared to participants who recorded the fewest dynamic sitting minutes (Q1), those with more dynamic sitting minutes had a lower BMI (Q2 = ?1.39 (95%CI = ?2.33;–0.46); Q3 = ?1.87 (?2.82;–0.92); Q4 = ?3.38 (?4.32;–2.45)), a smaller waist circumference (Q2 = ?2.95 (?5.44;–0.46); Q3 = ?3.47 (?6.01;–0.93); Q4 = ?8.21 (?10.72;–5.71)), and a lower odds for the metabolic syndrome (Q2 = 0.74 [0.45;1.20] Q3 = 0.58 [0.36;0.95]; Q4 = 0.36 [0.22;0.59]). Our findings suggest that dynamic sitting might be identified using accelerometry and that this behaviour was associated with health. This might be important given the large amounts of time people spend sitting. Future studies with a focus on validation, causation and physiological pathways are needed to further examine the possible relevance of dynamic sitting. 相似文献

Stroke in children is a heterogeneous disorder. Over 100 risk factors for stroke have been reported and genetic predisposition to stroke has been established. The most frequently reported risk factors are congenital heart malformations, hemolytic anemias, collagen vascular diseases, some rare inborn metabolic disorders, trauma, infection and thrombophilia. The aim of this article is to provide an overview of investigated inherited prothrombotic risk factors in children with first ischemic stroke. Various prothrombotic risk factors have been investigated in pediatric stroke including elevated homocysteine and lipoprotein (a), antithrombin, protein C and protein S deficiency, Factor V Leiden, Factor II G20210A and plasminogen activator inhibitor-1 4G/5G polymorphism. Despite similar criteria for inclusion of different studies in meta-analyses investigating first ischemic stroke in children, the obtained results were not consistent for all prothrombotic risk factors. The discrepancies found could be explained by methodological issues like different sample sizes, patient populations included and lack of controls. In order to provide the necessary power for randomized control trials, multi-center, multi-national approaches like International Pediatric Stroke Study have been initiated with the aim to describe risk factors for childhood stroke and explore their relationship with presentation, age, geography, and infarct characteristics. Although it is evident from numerous studies that the frequency of inherited prothrombotic factors is increased in pediatric stroke, single thrombophilia does not fully explain stroke in a child as it represents only a mild risk factor. Further studies are needed, as improved understanding of underlying mechanisms will improve primary and secondary prevention of childhood stroke. 相似文献

Little research has focused on tobacco use among deaf and hard of hearing youth. Findings are reported from a first-ever tobacco-related survey, completed by 226 California middle and high school students using either a written questionnaire or the Interactive Video Questionnaire, an interactive multimedia computer video technology. Rates for current smoking (3.1%), ever smoking (45.1%), and multiple types of tobacco use (10.6%) were found to be lower than among high school students generally; mainstreamed students were likelier to have ever tried smoking than their deaf school peers (57.8% vs. 31.8%). No statistically significant associations were found between ever smoking and race/ethnicity, gender, school performance, or prelingual vs. postlingual deafening; a quarter of the sample experienced occasional peer pressure to use tobacco products. Tobacco use covariates, exposure to cigarette marketing and antismoking programming, and tobacco education needs of deaf and hard of hearing youth are discussed. 相似文献
