Abstract
Results of an online survey distributed to faculty, PhD students, and researchers throughout Finland in 2016 show that library resources, journal articles, and books are important parts of scholars’ research and work life. The survey was disseminated through FinELib to heads of libraries, who were then asked to distribute it to their academic staff, researchers, and PhD students. The purpose of this study was to examine the value of readings obtained from library collections. To help answer this question, participants were asked about the amount and value of their reading and where they obtained readings, which allowed comparison of how the value of the library collection differs from other sources. The study found that researchers use many ways to identify and obtain articles, and the library collection is identified as one important source. Scholars use the library’s collection mostly to obtain articles for research and those articles help to inspire new ideas. Overall, this study demonstrates the importance of access to scholarly publications for scholars, from the library and elsewhere, such as open access sites and research sharing platforms.

Published: May 2019

OBJECTIVES:
Unnecessary use of antibiotics is an increasing problem. In this study, we sought to determine the diagnostic accuracy of procalcitonin in predicting bacteremia in children with a central line and fever, and we sought to determine optimal cutoff values to maximize sensitivity and specificity. This is the largest study to date in which procalcitonin is examined as a predictive marker of bacteremia in pediatric patients with a central line and fever.

METHODS:
We conducted a retrospective cohort study of children aged 0 to 23 years with a central line and fever of 38°C who had procalcitonin and blood cultures drawn before initiation of antibiotics and had no other identified bacterial infection. Patients were also prospectively monitored via a custom-built electronic medical record dashboard for eligibility.

RESULTS:
There were 523 patients and &gt;2500 procalcitonin values reviewed for eligibility. Of these, 169 (47%) patients and 335 blood cultures with procalcitonin were included. There were 94 (28%) positive bacterial blood cultures and 241 (72%) negative bacterial blood cultures. In bacteremic cultures, the mean procalcitonin level was 9.96 ± 15.96 ng/mL, and the median procalcitonin level was 4.85 ng/mL (interquartile range 18.5). In nonbacteremic cultures, the mean procalcitonin level was 1.23 ± 10.37 ng/mL, and the median procalcitonin level was 0.3 ng/mL (interquartile range 0.7). A receiver operating characteristic analysis indicated a procalcitonin level of ≥0.6 ng/mL as the best cutoff point that produced a sensitivity of 85.6% and a specificity of 65.7% (area under the curve 0.85).

CONCLUSIONS:
Procalcitonin is a sensitive biomarker in predicting bacteremia in children with a central line and fever.

Authors: Tyler Amy , Anderson Lauren , Moss Angela , Graham Jessica , Dempsey Amanda , Carpenter Todd 
Published: May 2019

OBJECTIVES:There are no data to inform the ideal length of in-hospital observation after symptom improvement or to inform the ideal dexamethasone dose in critically ill children with croup. We describe a cohort of critically ill children with croup who rebound (have return of symptom(s) after meeting hospital discharge criteria) and examine the association between the cumulative dexamethasone dose before PICU discharge and both the odds and timing of rebound.METHODS:In this single-center retrospective cohort study of subjects 6 months to 13 years of age admitted to the PICU with a primary diagnosis of croup, we employed multivariable logistic regression to evaluate the association between cumulative pre-PICU discharge dexamethasone dose and rebound. In the model, we controlled for subject age and sex, insurance, season, and history of prematurity, croup, or intubation. Kaplan-Meier curves were used to compare time to rebound between subjects receiving ≤2 standard (0.6 mg/kg) doses and those receiving &gt;2 standard doses of dexamethasone before PICU discharge.RESULTS:Data were analyzed over 69 months (January 2011–October 2016), and 275 unique subjects met inclusion criteria. The median cumulative dose of dexamethasone in the hospital was 1.57 mg/kg (interquartile range 0.98–2.63). Thirty-seven percent (n = 102) of subjects developed rebound croup symptoms after meeting hospital discharge criteria. The median time to rebound was 13.1 hours (interquartile range 6.1–23.7). There was no association between cumulative pre-PICU discharge dexamethasone dose and the odds (odds ratio = 1.00; 95% confidence interval 0.83–1.19; P = .96) or timing of rebound.CONCLUSIONS:A clinically significant number of critically ill patients with croup rebounded. Total pre-PICU discharge dexamethasone dose did not predict either the odds or timing of rebound.
Drosera in Ukraine: Ecological, сhorological specifics and phytosozonomical characteristics
Authors: Konishchuk V. V. , Skakalska O. I. 
Published: May 2019

The paper presents a chorologically systematized description of all taxa of the Drosera L. genus in Ukraine. We performed an analysis of environmental conditions, phytocoenotic characteristics and found new locations of sundew. We generalized the morphometric parameters and proposed a concept – “leaf roundness index”; and recommended including Drosera rotundifolia, Drosera x obovata in the next edition of the Red Data Book of Ukraine due to the contraction of their habitat and their high degree of vulnerability to unfavourable environmental factors and anthropogenic impact; we reccommend growing Drosera ex-situ on the example of Kremenets Botanical Garden with further repatriation in-situ; proved the efficiency of the proposed methods of farming cultivation. The paper substantiates the complex of phytosozological criteria, measures for protection and reproduction of the endangered species of Drosera genus. We suggested a hypothesis about the independence of the taxon of Drosera x obovata. Despite the fact that Drosera longifolia x D. rotundifolia is generally considered to be sterile hybrid, individuals breed vegetatively, are fertile and retain germinability after germination, and have a clearly specific ecotype, sometimes loci are isolated from parent species. To isolate the Drosera x obovata as a single taxon, additional phylogenetic studies are needed, but as a rare, disappearing taxon it needs protection and background monitoring of populations. The area of greatest phytosozological value for sundews in Ukraine is Western Polissia (Volyn, Rivne regions) (D. longifolia – 31, 20 sites, D. intermedia – 31 and 30 respectively). Drosera longifolia is on average distributed slightly further south in Ukraine than D. intermedia, although both taxa are confined to the humid, boreal zone. D. rotundifolia is most widespread in the humid zone (Polissia, the Carpathians). Despite the presence of Drosera x obovata in the Cheremskyi, Rivnenskyi Nature Reserve, Shatskyi National Nature Park, and several landscape reserves, the taxon is continuing to disappear due to succession, afforestation, water regime change etc.
Dancing with Deterrents: Understanding the Role of Abuse-Deterrent Opioid Formulations and Naloxone in Managing Cancer Pain
Authors: Mitchell Megan T. 
Published: May 2019

Abstract

Prescription opioids are commonly prescribed for the relief of many kinds of pain syndromes, including cancer pain. In order to combat the growing rates of abuse and misuse of prescription opioids, the Centers for Disease Control and Prevention, along with the U.S. Food and Drug Administration and multiple pharmaceutical companies, have implemented many risk mitigation strategies. Abuse-deterrent drug delivery technology and more consistent prescribing of the opioid antagonist, naloxone, are two of the mechanisms of reducing harm in patients on chronic opioid therapy. Abuse-deterrent technology is implemented into different commercially available opioid products with the intent of discouraging manipulation of the opioid or making the use of the manipulated opioid less appealing. Use of the opioid antagonist, naloxone, for reversal of intentional or unintentional opioid overdose is a safe and effective means to reduce potential risk in patients who are on opioids for pain management. These mechanisms have multiple advantages and limitations that influence their practical use specifically in patients with cancer pain. Patients with cancer pain have unique therapeutic needs and goals, and their balance of treatment risks and benefits differs from that of other kinds of chronic pain disorders. This article provides an overview of the advantages and limitations of these specific harm-reduction strategies and provides guidance on how to practically utilize them when caring for patients with cancer pain.

Implications for Practice
Treating cancer pain has important and unique considerations compared with other chronic, noncancer pain disorders. The use of risk mitigation strategies for opioid prescribing as promoted by the Centers for Disease Control and Prevention does not translate seamlessly to patients with cancer. It is crucial to be wary of the advantages and pitfalls of all risk mitigation strategies related to opioid use in patients with cancer pain. Careful examination of patient-specific risks and benefits should always be considered when implementing pharmacologic treatment and harm-reduction strategies for the management of cancer pain.

KARAKTERISASI SIFAT LISTRIK GRAFIT SETELAH IRADIASI DENGAN SINAR-g. Telah dilakukan penelitan tentang karakterisasi sifat listrik grafit hasil iradiasi dengan sinar-g. Serbuk grafit dibuat dalam bentuk pelet dengan daya tekan sampai 20 ton. Pada penelitian ini, diamati perubahan sifat listrik grafit setelah diiradiasi dengan sinar-g pada berbagai variasi dosis (100 kGy – 600 kGy). Karakterisasi sifat listrik grafit dilakukan dengan menggunakan alat ukur LCR meter. Hasil pengukuran sifat listrik pelet grafit dengan LCR menunjukkan bahwa nilai konduktivitas dan kapasitansi listrik grafit meningkat akibat radiasi sinar-g, dan nilai ini semakin meningkat seiring dengan bertambahnya dosis radiasi. Peningkatan nilai ini mencapai sekitar 43,2 % untuk nilai konduktivitas dan sekitar 55,4 % untuk nilai kapasitansi setelah diirradiasi dengan sinar-g sampai dosis 600 kGy. Peningkatan nilai ini diperkirakan akibat meningkatnya frekuensi interaksi antara radiasi sinar-g dengan bahan grafit (dalam hal ini adalah elektron), yang menyebabkan daya tampung listriknya meningkat, sehingga sifat listrik bahan grafit tersebut menjadi lebih besar.

ABSTRAK Analisis EFISIENSI TRAFO FREKUENSI TINGGI PADA SUMBER TEGANGAN TINGGI COCKCROFT WALTON MBE LATEK.. Trafo frekuensi tinggi (TFT) 1 fasa, 15 kW, 7/17,5 kV, 40 kHz yang dibuat telah dioperasikan pada MBE namun belum diketahui karakteristiknya. Efisiensi merupakan karakteristik TFT yang penting untuk dianalisis dalam rangka mengetahui kemampuannya dalam mencatu daya STT-MBE pada berbagai arus berkas elektron. Analisis dilakukan dengan menghitung rugi-rugi inti dan rugi-rugi lilitan dimana rugi inti tergantung pada bahannya, sedangkan rugi lilitan tergantung pada arus dan tahanannya dengan memperhatikan kenaikan suhu yang terjadi saat dioperasikan. Pada induksi magnet maksimum Bm 0,15 T dan frekuensi operasi 40 kHz, diketahui rugi daya inti 611,78 W sedangkan rugi daya lilitan total 9,85 W pada beban penuh 1,07 A sehingga efisiensi trafo pada beban penuh 96,02 %. Efisiensi trafo dihitung dengan variasi arus beban atau arus berkas elektron Ibe dimana rugi daya lilitan berbanding kuadrat terhadap arus beban. Efisiensi maksimum (hm) TFT di bawah beban penuh adalah sebesar 95,71 % terjadi pada Ibe 11 mA atau 92,4 % beban penuh. Pada Ibe yang lebih besar misalnya 12 mA, TFT mengalami kondisi beban lebih sebesar 9,34 %. Jika dibandingkan dengan trafo tenaga yang mempunyai efisiensi maksimum sekitar 80 % beban penuh, maka TFT yang dibuat mempunyai efisiensi maksimum pada persen beban yang lebih besar. Efisiensi TFT juga mempunyai kecenderungan sama dengan jenis trafo tenaga yaitu semakin besar bila bebannya semakin besar.
Ethical reasons for the regulation of gametes’ donation and co-parenting
Authors: Savvina O. V. 
Published: May 2019

The article analyzes the practice of legislative regulation of the gametes’ donation and its ethical grounds. Gametes’ donation is often used in conjunction with assisted reproductive technologies to treat infertility and/or family planning. The study applies an interdisciplinary approach: it is based on the research carried out in the field of philosophy (bioethics), law, medicine with the application of sociological surveys.The article shows that the introduction of this practice affects traditional family values, blurs fraternal-sisterly relations making genetic brothers and sisters strangers to each other, transforms the family creating its new forms through the practice of co-parenting that is gaining popularity in English-speaking countries. Also, the article identifies the problem of negative attitude of religious authorities to the practice of donating gametes. The legislative regulation cannot but take into account the public sentiment; and the percentage of believers in the State when implementing the laws regulating the donation of gametes is an important factor. Another important problem discussed in the article concerns the welfare and rights of a future child conceived with the help of the donation of gametes, his or her «right to know» and «right not to know» the birth secret.

Mr. Gaga: Embodying the Exceptionalism of Ohad Naharin
Authors: Quinlan Meghan 
Published: May 2019

The life and work of Israeli choreographer Ohad Naharin are documented in the 2015 film by Tomer Heymann, Mr. Gaga. With nearly a decade of footage from following Naharin’s work with the Batsheva Dance Company, the documentary celebrates Naharin’s life with abundant footage from his choreographic successes. This article explores the ways in which this film, like many dance documentaries, uses dance footage in strategic ways to present dance artists as exceptional. In Mr. Gaga in particular, the national and cultural specificity of the story and footage portrayed in the film require critical analysis to better understand subtle political undertones and bias embedded in the film’s otherwise primarily aesthetic focus.
