Abstract
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes with which the qubits can interact, causing irreversible decay of the quantum state. As a practical matter, however, there exists a high density of excitations out of the superconducting ground state even at ultralow temperature; these are known as quasiparticles. Observed quasiparticle densities are of order 1 μm^{-3}, tens of orders of magnitude greater than the equilibrium density expected from theory. Nonequilibrium quasiparticles extract energy from the qubit mode and can induce dephasing. Here we show that a dominant mechanism for quasiparticle poisoning is direct absorption of high-energy photons at the qubit junction. We use a Josephson junction-based photon source to controllably dose qubit circuits with millimeter-wave radiation, and we use an interferometric quantum gate sequence to reconstruct the charge parity of the qubit. We find that the structure of the qubit itself acts as a resonant antenna for millimeter-wave radiation, providing an efficient path for photons to generate quasiparticles. A deep understanding of this physics will pave the way to realization of next-generation superconducting qubits that are robust against quasiparticle poisoning.

Abstract
BACKGROUND Many children with injuries, including burns and fractures, experience moderate to severe pain during medical procedures. Recent studies claim that nonpharmacologic pain management using virtual reality (VR) could distract children from procedural pain by engaging multiple senses. AIMS The aims of this pilot randomized clinical trial were to assess the acceptability and feasibility of VR distraction in children with burns or fractures undergoing painful medical procedures, as well as the staff nurses, and assess the preliminary efficacy of VR distraction on pain intensity, pain-related fear, and subsequent recall of both. MATERIALS AND METHOD A within-subject study design, in which participants served as their own control, was used. A total of 20 children from 7 to 17 years old with an injury were recruited at the surgical-trauma outpatient clinics of the Centre hospitalier universitaire Sainte-Justine (CHU Sainte-Justine). Each participant received both standard and experimental treatments through randomized order. Pain (numerical rating scale) and pain-related fear (Children's Fear Scale) measures were taken before the procedure and after each sequence, followed by a measure of children's (graphic rating scale) and nurses' acceptability of the intervention through their satisfaction level. Recall of pain intensity and pain-related fear were assessed 24 hours after the procedure. Wilcoxon signed-rank tests were used, with a significance level at 0.05. RESULTS Results showed that VR distraction was an acceptable and feasible intervention for children and nurses of these outpatient clinics. Preliminary effects showed that, compared to standard of care, children participants reported a significant decrease in pain intensity (p = .023) and pain-related fear (p = .011) during VR as well as less recalled pain-related fear (p = .012) at 24 hours after the procedure. No side effects were reported. CONCLUSION VR is a promising intervention with children undergoing painful procedures because it is immersive and engages multiple senses. It is a low-cost intervention well accepted by children and nursing staff at this clinical site and is easy to implement in daily practice for procedural pain management.

Abstract
AIMS To examine the efficacy of an immersive virtual reality distraction compared with an active non-immersive distraction, such as video games on a tablet, for pain and anxiety management and memory of pain and anxiety in children requiring percutaneous bone pins and/or suture removal procedures. DESIGN Three-centre randomized clinical trial using a parallel design with two groups: experimental and control. METHODS Study to take place in the orthopaedic department of three children hospital of the Montreal region starting in 2019. Children, from 7-17 years old, requiring bone pins and/or suture removal procedures will be recruited. The intervention group (N = 94) will receive a virtual reality game (Dreamland), whereas the control group (N = 94) will receive a tablet with video games. The primary outcomes will be both the mean self-reported pain score measured by the Numerical Rating Scale and mean anxiety score, measured by the Child Fear Scale. Recalls of pain and anxiety will be measured 1 week after the procedure using the same scales. We aim to recruit 188 children to achieve a power of 80% with a significance level (alpha) of 5%. DISCUSSION While multiple pharmacological methods have previously been tested for children, no studies have evaluated the impact of immersive virtual reality distraction for pain and anxiety management in the orthopaedic setting. IMPACT Improved pain management can be achieved using virtual reality during medical procedures for children. This method is innovative, non-pharmacological, adapted to the hospital setting, and user-friendly. TRIAL REGISTRATION NCT03680625, registered on clinicaltrials.gov.

Abstract
Background: Opioids are commonly prescribed to hospitalized adults to promote adequate pain relief, yet they can cause potentially fatal respiratory depression. Aim: The aim of this study was to examine the risk factors for the development of severe opioid-induced respiratory depression (OIRD) in hospitalized adults to ensure adequate monitoring of high-risk patients. Methods: A retrospective case–control study was conducted using data from the medical records of a university-affiliated hospital in Canada. Cases were eligible if they were adults (≥18 years old) and received opioid analgesia within 24 h of naloxone administration for respiratory depression. Controls had the same eligibility criteria, except for respiratory depression and naloxone administration. The case–control ratio was 1:1, and they were matched based on sex, type of unit, opioid molecule and the presence/absence of medication errors. Results: A total of 133 cases and 133 controls were included. Following cumulative risk factor analysis, renal failure (odds ratio [OR] = 2.176, 95% confidence interval [CI], 1.021–4.640, P = 0.044), the first 24 h of opioid administration (OR = 1.899, 95% CI, 1.090–3.309, P = 0.024), concomitant central nervous system (CNS) depressants (OR = 1.785, 95% CI, 1.023–3.113, P = 0.041), and increasing age (OR = 1.019, 95% CI, 1.002–1.035, P = 0.028) were positively associated with severe OIRD. Conclusions: Some adult hospitalized patients were at higher risk of experiencing severe OIRD, such as those with renal failure, those in their first 24 h of opioid administration, those receiving CNS depressants in addition to opioids, and those with an advanced age. These results will assist with the screening of patients at higher risk for severe OIRD, which is key to implementing appropriate monitoring and enhancing the safety of opioid use in hospital settings.

Abstract
BACKGROUND Practitioner-level implementation interventions such as audit and feedback, communities of practice, and local opinion leaders have shown potential to change nurses' behaviour in clinical practice and improve patients' health. However, their effectiveness remains unclear. Moreover, we have a paucity of data regarding the use of theory in implementation studies with nurses, the causal processes-i.e. mechanisms of action-targeted by interventions to change nurses' behaviour in clinical practice, and the constituent components-i.e. behaviour change techniques-included in interventions. Thus, our objectives are threefold: (1) to examine the effectiveness of practitioner-level implementation interventions in changing nurses' behaviour in clinical practice; (2) to identify, in included studies, the type and degree of theory use, the mechanisms of action targeted by interventions and the behaviour change techniques constituting interventions and (3) to examine whether intervention effectiveness is associated with the use of theory or with specific mechanisms of action and behaviour change techniques. METHODS We will conduct a systematic review based on the Cochrane Effective Practice and Organization of Care (EPOC) Group guidelines. We will search six databases (CINAHL, EMBASE, ERIC, PsycINFO, PubMed and Web of Science) with no time limitation for experimental and quasi-experimental studies that evaluated practitioner-level implementation interventions aiming to change nurses' behaviour in clinical practice. We will also hand-search reference lists of included studies. We will perform screening, full-text review, risk of bias assessment, and data extraction independently with the Covidence systematic review software. We will assess the quality of evidence using the GRADEpro software. We will code included studies independently for theory use (Theory Coding Scheme), mechanisms of action (coding guidelines from Michie) and behaviour change techniques (Behaviour Change Technique Taxonomy v1) with QSR International's NVivo qualitative data analysis software. Meta-analyses will be performed using the Review Manager (RevMan) software. Meta-regression analyses will be performed with IBM SPSS Statistics software. DISCUSSION This review will inform knowledge users and researchers interested in designing, developing and evaluating implementation interventions to support nurses' behaviour change in clinical practice. Results will provide key insights regarding which causal processes-i.e. mechanisms of action-should be targeted by these interventions, and which constituent components-i.e. behaviour change techniques-should be included in these interventions to increase their effectiveness. SYSTEMATIC REVIEW REGISTRATION The protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42019130446).

Abstract
INTRODUCTION Needle-related procedures are considered as the most important source of pain and distress in children in hospital settings. Considering the physiological and psychological consequences that could result from these procedures, management of pain and distress through pharmacological and non-pharmacological methods is essential. Therefore, it is important to have interventions that are rapid, easy-to-use and likely to be translated into clinical practice for routine use. The aim of this study will be to determine whether a device combining cold and vibration (Buzzy) is non-inferior to a topical anaesthetic (liposomal lidocaine 4% cream) for pain management of children undergoing needle-related procedures in the emergency department. METHODS AND ANALYSIS This study will be a randomised controlled non-inferiority trial comparing the Buzzy device to liposomal lidocaine 4% cream for needle-related pain management. A total of 346 participants will be randomly assigned in a 1:1 ratio to one of the two study groups. The primary outcome will be the mean difference in pain intensity between groups during needle-related procedures. A non-inferiority margin of 0.70 on the Color Analogue Scale will be considered. A Non-inferiority margin of 0.70 on the Color Analogue Scale will be considered. The secondary outcomes will be the level of distress during the procedure, the success of the procedure at first attempt, the occurrence of adverse events, the satisfaction of both interventions and the memory of pain 24 hours after the procedure. The primary outcome will be assessed for non-inferiority and the secondary outcomes for superiority. ETHICS AND DISSEMINATION This study protocol was reviewed and approved by the institutional review board of the study setting. Findings of this trial will be disseminated via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER NCT02616419.

Abstract
BACKGROUND Needle-related procedures are the most important source of pain in children in hospital setting. Unmanaged pain could result in short- and long-term physiological, psychological, and emotional consequences. Although the efficacy of numerous interventions has been evaluated, procedural pain management is often suboptimal in children undergoing needle-related procedures. The main objective of this systematic review is to examine the evidence for the efficacy of the Buzzy® device for needle-related procedural pain in children. METHODS An electronic search will be conducted in the following databases: CENTRAL, PubMed, MEDLINE, EMBASE, PsycInfo, and CINAHL. There will be no restriction regarding the language, date of publication, and publication status. Eligible studies will be randomized controlled trials using the Buzzy® device for pain management in children undergoing needle-related procedures. Selection of studies, data extraction and management, assessment of risk of bias and quality of evidence will be performed by two independent reviewers. A third researcher will be consulted in case of discrepancies. Depending on the availability and quality of the data as well as clinical and statistical heterogeneity, a meta-analysis will be performed. Otherwise, findings will be qualitatively reported. DISCUSSION This will be the first systematic review to examine the efficacy of the Buzzy® device on pain management of children during needle-related procedures. Results of this review will guide clinical practice and recommendations for further research to improve procedural pediatric pain management. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42017076531.

Abstract
BACKGROUND Virtual reality (VR) is a non-pharmacological method to distract from pain during painful procedures. However, it was never tested in young children with burn injuries undergoing wound care. AIM We aimed to assess the feasibility and acceptability of the study process and the use of VR for procedural pain management. METHODS From June 2016 to January 2017, we recruited children from 2 months to 10 years of age with burn injuries requiring a hydrotherapy session in a pediatric university teaching hospital in Montreal. Each child received the projector-based VR intervention in addition to the standard pharmacological treatment. Data on intervention and study feasibility and acceptability in addition to measures on pain (Face, Legs, Activity, Cry, Consolability scale), baseline (Modified Smith Scale) and procedural (Procedure Behavior Check List) anxiety, comfort (OCCEB-BECCO [behavioral observational scale of comfort level for child burn victims]), and sedation (Ramsay Sedation Scale) were collected before, during, and after the procedure. Data analyses included descriptive and non-parametric inferential statistics. RESULTS We recruited 15 children with a mean age of 2.2±2.1 years and a mean total body surface area of 5% (±4). Mean pain score during the procedure was low (2.9/10, ±3), as was the discomfort level (2.9/10, ±2.8). Most children were cooperative, oriented, and calm. Assessing anxiety was not feasible with our sample of participants. The prototype did not interfere with the procedure and was considered useful for procedural pain management by most health care professionals. CONCLUSION The projector-based VR is a feasible and acceptable intervention for procedural pain management in young children with burn injuries. A larger trial with a control group is required to assess its efficacy.

Abstract
BACKGROUND Musculoskeletal injuries (MSK-Is) are a common and painful condition among children that remains poorly treated in the emergency department (ED). We aimed to test the efficacy of a combination of an anti-inflammatory drug with an opioid for pain management of MSK-I in children presenting to the ED. METHODS In this randomized, double-blinded, placebo-controlled trial, we enrolled children between 6 and 17 years presenting to the ED with an MSK-I and a pain score >29 mm on the visual analog scale (VAS). Participants were randomly assigned to oral morphine (0.2 mg/kg) + ibuprofen (10 mg/kg) (morphine + ibuprofen) or morphine (0.2 mg/kg) + placebo of ibuprofen or ibuprofen (10 mg/kg) + placebo of morphine. Primary outcome was children with VAS pain score <30 mm at 60 minutes postmedication administration. RESULTS A total of 501 participants were enrolled and 456 were included in primary analyses (morphine + ibuprofen = 177; morphine = 188; ibuprofen = 91). Only 29.9% (morphine + ibuprofen), 29.3% (morphine), and 33.0% (ibuprofen) of participants achieved the primary outcome (P = .81). Mean VAS pain reduction at 60 minutes were -18.7 (95% confidence interval [CI]: -21.9 to -16.6) (morphine + ibuprofen), -17.0 (95% CI: -20.0 to -13.9) (morphine), -18.6 (95% CI: -22.9 to -14.2) (ibuprofen) (P = .69). Children in the morphine + ibuprofen group (P < .001) and in the morphine group (P < .001) experienced more side effects than those in the ibuprofen group. No serious adverse event was reported. CONCLUSIONS Combination of morphine with ibuprofen did not provide adequate pain relief for children with MSK-I in the ED. None of the study medication provided an optimal pain management because most of children did not reach a mild pain score (NCT02064894).

Abstract
Background Adolescent idiopathic scoliosis (AIS) is among the most common spinal deformities affecting adolescents. The Scoliosis Research Society-22 questionnaire is commonly used to assess health-related quality of life in AIS patients, including pain. The objective of this study is to verify the psychometric properties of the Scoliosis Research Society-22 French version (SRS-22fv) questionnaire. Methods A prospective methodological design was used to verify the psychometric properties of the French version of the SRS-22fv. Participants were initially recruited from the orthopaedic scoliosis department at Sainte-Justine Hospital (Montreal, Canada) and completed the SRS-22fv and the SF-12 questionnaire. The SRS-22fv’s structure was evaluated through principal component analysis (PCA). Linear regression was used to assess convergent validity between the SRS-22fv and the SF-12. Results Data was available from 352 participants with AIS. Most participants were female (87%, n = 307), and the average age was 14.3 (SD = 1.8) years. The mean thoracic and lumbar Cobb angles were 27.9° (SD = 3.3) and 23.6° (SD = 9.4), respectively. Overall, 71.4% (n = 252) of the participants presented with spinal pain. About one-third (29%) reported thoracic pain, and almost half (44%) experienced lumbar pain. The PCA identified four redundant items, which resulted in a modified 18-item questionnaire. In comparison to the original questionnaire, the modified version showed higher levels of internal consistency for four of the five factors, explained a greater proportion of the total variance (63.3%), and generated higher inter-item total correlations. Conclusion We propose a shorter version of the SRS-22fv, thus the Canadian SRS-18fv, which showed an improved internal consistency and scale structure compared to the original SRS-22fv. We believe that this modified version would be better suited to assess the quality of life of adolescents with idiopathic scoliosis.

Abstract
Background Adolescent idiopathic scoliosis is the most common spinal deformity occurring in adolescents and its established prevalence varies from 2 to 3%. Adolescent idiopathic scoliosis has been identified as a potential risk factor for the development of low back pain in adolescents. The purpose of this study was to systematically review studies of the prevalence of low back pain in adolescents with idiopathic scoliosis in order to establish the quality of the evidence and determine whether the prevalence estimates could be statistically pooled. Methods Systematic electronic searches were undertaken in PubMed, CINAHL, and CENTRAL without any restrictions. Studies were eligible for inclusion if they reported the prevalence of low back pain in adolescents with idiopathic scoliosis. Studies were excluded if they detailed the prevalence of pain in post-surgical subjects or were published in languages other than English or French. Data were reported qualitatively, since there was insufficient evidence for statistical pooling. Results The electronic search strategies yielded 1811 unique studies. Only two studies fulfilled the eligibility criteria. The prevalence of low back pain in adolescents with idiopathic scoliosis ranged from 34.7 to 42.0%. However, these prevalence estimates should be viewed cautiously as the included studies were at high risk of bias. Conclusion The results of this systematic review indicate that adolescents with idiopathic scoliosis frequently experience low back pain. However, there was insufficient evidence to confidently estimate low back pain prevalence in adolescents with idiopathic scoliosis and further studies are needed in this area.

Abstract
Background Spinal fusion is a common orthopedic surgery in children and adolescents and is associated with high pain levels postoperatively. If the pain is not well managed, negative outcomes may ensue. To our knowledge, there is no measure in English that assesses patient’s satisfaction with postoperative pain management following idiopathic scoliosis surgery. The aim of the present study was to assess the psychometric properties of the satisfaction subscale of the English version of the Satisfaction of Adolescents with Postoperative pain management – idiopathic Scoliosis (SAP-S) scale. Methods Eighty-two participants aged 10–18 years, who had undergone spinal fusion surgery, fully completed the SAP-S scale at 10–14 days postdischarge. Construct validity was assessed through a principal component analysis using varimax rotation. Results Principal component analysis indicated a three-factor structure of the 13-item satisfaction subscale of the SAP-S scale. Factors referred to satisfaction regarding current medication received (Factor 1), actions taken by nurses and doctors to manage pain (Factor 2) and information received after surgery (Factor 3). Cronbach’s alpha was 0.91, showing very good internal consistency. Data on satisfaction and clinical outcomes were also reported. Conclusion The SAP-S is a valid and reliable measure of satisfaction with postoperative pain management that can be used in both research and clinical settings to improve pain management practices. Although it was developed and validated with adolescents who had undergone spinal fusion surgery, it can be used, with further validation, to assess adolescents’ satisfaction with pain management in other postoperative contexts.

Abstract
Background: Spinal fusion for scoliosis generates moderate to severe pain intensity. There are currently no instruments available to measure adolescents’ satisfaction regarding post-spinal fusion pain management. Aims: To develop and validate a scale on satisfaction of adolescents regarding pain management following spinal fusion for scoliosis. Methods: A methodological design was used to develop and validate the French-Canadian scale “Satisfaction des Adolescents de la gestion de la Douleur postopératoire – Scoliose idiopathique (SAD-S)”. A modified Delphi method, with seven healthcare professionals and 10 adolescents, was used to establish content validity of the SAD-S. A pre-test of the scale was conducted with 10 adolescents post-spinal fusion. The final version of the scale was validated through a pilot study with 98 adolescents following their surgery. Results: The SAD-S scale includes a total of 13 items. Principal component analysis yielded a two-factor structure (2 subscales): 1) Pain management education and 2) Education regarding medication. These two factors explained 47,8% of the total variance for satisfaction. A Cronbach’s alpha of 0,84 was obtained for internal consistency. Conclusion: Validation of the SAD-S scale showed that it has good psychometric properties with this population. Further validation is required with a larger sample to pursue its validation.

Abstract
Abstract
BACKGROUND: A single-agent approach to children’s moderate to severe pain is often inadequate. To date, no studies have evaluated the combined use of oral morphine and ibuprofen for optimal pain management of children presenting to an emergency department (ED) for muscu-loskeletal (MSK) trauma.
OBJECTIVES: To assess the efficacy of a combination of oral morphine and ibuprofen for pain management in children with MSK trauma in the ED.
DESIGN/METHODS: A double-blind, placebo-controlled, multi-centered, three-arm, randomized clinical trial of 500 patients was conducted at three pediatric tertiary care EDs. Patients were randomized (in a 2:1:1 ratio) to receive (orally): (a) morphine (0.2mg/kg) + ibuprofen (10mg/kg) (Group MOR + IBU) or (b) morphine (0.2 mg/kg) + placebo (Group MOR) or (c) ibuprofen (10mg/kg) + placebo (Group IBU). Patients 6 to 17 years of age, who presented to the ED with a MSK trauma, and a score >30 mm on the 100mm visual analogue scale were eligible to participate. Primary outcome was pain intensity score under 30 mm (mild pain) at 60-minutes (T-60) after treatment administration.
RESULTS: A total of 456 patients were included in analyses: 177 (MOR + IBU), 188 (MOR), 91 (IBU). Mean age was 11.9±2.7 years, with a majority of boys (55.3%) and Soft tissue injuries (62%). There were no differences in baseline characteristics in the three groups. Baseline mean pain score was 60.9±16.2 mm. Only 30% (MOR + IBU), 29% (MOR) and 30% (IBU) of patients reached a pain score under 30 mm at T-60 (p=0.83). Mean pain scores at T-60 were 42.3±23.2 mm (MOR + IBU), 43.8 + 23.1 mm (MOR) and 42.3±23.3 mm (IBU) (p=0.83). No severe adverse events were observed in any of the groups, at any of the study measurement points.
CONCLUSION: Combination of morphine with ibuprofen did not provide any additional pain relief for children with MSK injuries, in the ED. None of the study medication provided optimal pain management, as the majority of children did not reach the WHO definition of mild pain. Alternative analgesic combinations should be investigated to optimize pain relief of children who present to the ED with MSK injuries.

INTRODUCTION doctoral studies in nursing engage a critical reflections about philosophical traditions inherent to knowledge development. BACKGROUND critical realism, hermeneutics, postmodernism and poststructuralism refer to philosophical traditions that are generally less explored in nursing, although they are attracting greater attention. OBJECTIVE this paper offers an introductory presentation to these traditions as the authors also reflect upon their contribution to nursing knowledge development in. METHOD for each tradition, ontological and epistemological properties are presented to provide an overview of their main features. Contributions to nursing knowledge development are then discussed. RESULTS ontology refers to stratified, fixed and changing, or multiple realities, depending on the philosophical tradition. Likewise, epistemology emphasizes the explanatory power of knowledge, intersubjectivity, or inherent power dynamics. DISCUSSION the diversity of philosophical traditions represents an asset that can significantly contribute to the advancement of the nursing discipline. CONCLUSION clarification of the philosophical dimensions that underlie knowledge development is essential for doctoral nursing students in the process of developing their research projects and future programmes of research.

Abstract
Low density lipoprotein (LDL) induces intercellular adhesion molecule-1 (ICAM-1) gene expression and leads to endothelial cell (EC) leukocyte adhesion. However, the transcriptional mechanism for LDL-induced EC perturbation remains to be fully explained. Activator protein-1 (AP-1) is induced after the exposure of ECs to LDL. In the present study, a regulated adenovirus expressing a dominant-negative mutant of c-Jun (TAM-67) was used to examine the role of AP-1 in the LDL-induced ICAM-1 activation. Overexpression of TAM-67 specifically inhibited AP-1 activation and prevented the LDL-activated surface expression of ICAM-1 protein in human umbilical vein ECs and human coronary artery ECs. Northern analyses and promoter transactivation assays indicated that this effect of TAM-67 was likely mediated through a suppression of the transcriptional regulation of the ICAM-1 gene. Functionally, TAM-67 attenuated leukocyte adherence to ECs in response to LDL. Furthermore, electrophoresis mobility shift assays and site-directed mutagenesis suggested that an AP-1-like motif in the promoter region of the human ICAM-1 gene was a critical cis element for LDL induction. These results, for the first time, provide evidence suggesting that AP-1 is a major regulatory mechanism leading to endothelial activation.

Abstract
Leptin, the product of the ob gene, regulates food intake, energy expenditure, and other physiological functions of the peripheral tissues. Leptin receptors have been identified in the hypothalamus and in extrahypothalamic tissues. Increased circulating leptin levels have been correlated with cardiovascular disease, obesity, aging, infection with bacterial lipopolysaccharide, and high-fat diets. All these conditions have also been correlated with increased vascular calcification, a hallmark of atherosclerotic and age-related vascular disease. In addition, the differentiation of marrow osteoprogenitor cells is regulated by leptin. Thus, we hypothesized that leptin may regulate the calcification of vascular cells. In this report, we tested the effects of leptin on a previously characterized subpopulation of vascular cells that undergo osteoblastic differentiation and calcification in vitro. When treated with leptin, these calcifying vascular cells had a significant 5- to 10-fold increase in alkaline phosphatase activity, a marker of osteogenic differentiation of osteoblastic cells. Prolonged treatment with leptin enhanced the calcification of these cells, further supporting the pro-osteogenic differentiation effects of leptin. Furthermore, the presence of the leptin receptor on calcifying vascular cells was demonstrated using reverse transcriptase polymerase chain reaction, immunocytochemistry, and Western blot analysis. We also identified the presence of leptin receptor in the mouse artery wall, localized to subpopulations of medial and adventitial cells, and the expression of leptin by artery wall cells and atherosclerotic lesions in mice. Taken together, these results suggest that leptin regulates the osteoblastic differentiation and calcification of vascular cells and that the artery wall may be an important peripheral tissue target of leptin action.

Abstract
PURPOSE/OBJECTIVES To compare levels of hope in patients with newly diagnosed and recurrent cancer. DESIGN Descriptive study. SETTING Three oncology practices in two urban areas of the southern United States. SAMPLE Convenience sample of 20 newly diagnosed patients with cancer and 16 patients with recurrent cancer (mean age = 56 years). The majority of the patients were Caucasian, female, and married; had a high school degree; and had a religious affiliation. METHODS Subjects completed the Herth Hope Scale and answered the open-ended question "What gives you the most hope at the present time?" Analysis included descriptive statistics (i.e., frequency, means, standard deviations, percents), t-tests, Chi-square, and analysis of variance. MAIN RESEARCH VARIABLES Level of hope each subject had in relation to the stage of the cancer at the time of diagnosis. FINDINGS Contrary to expectations, patients with newly diagnosed and recurrent cancer did not differ in regard to their level of hope. However, significant differences were found related to the type of hope utilized. Married patients and male patients experienced higher levels of hope. Recurrent themes in response to the open-ended question were family support, nonfamily support, faith, outlook, and health professionals/care. CONCLUSIONS Patients with newly diagnosed cancer use their treatment and nurses, physicians, and other healthcare professionals as sources of hope and support. Patients with recurrent cancer reported drawing hope from faith. IMPLICATIONS AND NURSING PRACTICE: Heightened awareness of the patient-healthcare professional relationship will enable healthcare professionals to provide care that is more sensitive to one congruent with patients' needs. Healthcare professionals need to assess the meaning of faith for each individual patient and offer services to foster this source of hope.

Abstract
Three variants of group A rotavirus with large changes in their gene 5 structures have been analyzed at the molecular level. The first of these, P9 delta 5, was obtained during plaque purification undertaken as part of the biological cloning of a field isolate of virus. The gene 5 homolog in this isolate migrated just ahead of the normal segment 6 RNA, giving an estimated size of 1,300 bp. Molecular cloning and sequencing of this homolog revealed it to have a single 308-bp deletion in the center of the normal gene 5 sequence extending between nucleotides 460 and 768 of the normal gene sequence. This deletion caused a frameshift in the gene such that a stop codon was encountered 8 amino acids downstream of the deletion point, giving a predicted size for the protein product of this gene of 150 amino acids compared with the 490 amino acids of its normal-size counterpart. Attempts to detect this shortened protein in virus-infected cells were not successful, indicating that it was much less stable than the full-length protein and/or had suffered a large change in its antigenicity. The second two variants, brvA and brvE, were generated in an earlier study following the high-multiplicity passage of the UKtc strain of bovine rotavirus. Polyacrylamide gel electrophoresis analysis of these nondefective variants showed that brvA had a gene 5 homolog approximately equal in size to the normal RNA segment 2 (approximately 2,700 bp) and that brvE had a size of approximately 2,300 bp. Both variants showed changes in their gene 5 protein products, with brvA mimicking P9 delta 5 in failing to produce a detectable product whereas brvE produced a new virus-specific protein approximately 80 kDa in size. Full-length cDNA clones of the brvE gene 5 homolog were isolated, and analysis of their structure revealed a head-to-tail concatemerization of the normal gene 5 sequence with the first copy of the concatemer covering nucleotides 1 to 808 and the second covering nucleotides 92 to 1579, giving a total length of 2,296 bp. Sequencing across the junction region of the two copies of the gene showed that they were joined in frame to give a predicted combined open reading frame of 728 amino acids with the amino-terminal region consisting of amino acids 1 to 258 fused at the carboxy terminus to amino acids 21 to 490.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Rotaviruses with genome rearrangements isolated from a chronically infected immunodeficient child (F. Hundley, M. McIntyre, B. Clark, G. Beards, D. Wood, I. Chrystie, and U. Desselberger, J. Virol 61:3365-3372, 1987) are the first recognized human isolates of serotype 10. This was shown by both a direct enzyme-linked immunosorbent assay and virus neutralization assays using serotype specific monoclonal antibodies. The serotype was confirmed by sequence analysis of the gene encoding VP7, which revealed a 96% amino acid homology to the bovine serotype 10 isolate B223.

Abstract
Normal and rearranged RNA segments 10 of group A rotaviruses isolated from a chronically infected immunodeficient child were amplified by the polymerase chain reaction as full-length cDNA copies, and were subsequently cloned and sequenced. Compared with the nucleotide sequence of the normal RNA segment 10, the rearranged form contains a partial non-coding duplication at its 3' end and several point mutations. The normal RNA segment 10 was similar to that of bovine rotavirus.

Abstract
Ligamentous injuries to the knee do occur in children with open physes. Rarely, the posterior cruciate ligament may be involved and prompt attention to repair when recognized is encouraged. While avulsion occurs, more commonly, from the femoral insertion of the posterior cruciate, the tibial origin may be the site of injury, as in this case report. Complete examination of fractured femurs in children is therefore necessary. Early ligamentous repair is superior to later reconstruction.

Abstract
This study identified five plantar fascial spaces of the foot. The first space lies superficial to the calcaneus, the second lies between the plantar aponeurosis and the flexor digitorum brevis, the third lies between the flexor digitorum brevis and the quadratus plantar, the fourth lies above the quadratus, and the fifth lies above the adductor hallucis. A plantar incision is proposed for exploration and drainage of foot injuries and infections. With this incision, the plantar neurovascular bundles, along with the five plantar spaces through which infection spreads, are visualized clearly. In our experience, the incision heals without a sensitive scar.

Abstract
A double-blind prospective study involving 1,591 clean orthopedic surgical procedures was done to test the effectiveness of preoperative and intraoperative antibiotics in reducing the postoperative infection rate. The antibiotic and placebo groups were analyzed carefully for factors known to predispose to infection. Several minor exceptions were noted, but generally the antibiotic and placebo groups were comparable with regard to these factors. A decrease in overall postoperative infection rate from 5.0% in the placebo group to 2.8% in the antibiotic group was found. In specific areas such as the hip and spine a much greater reduction in postoperative wound infections occurred than in the group as a whole.

Abstract
A method of treatment of pyogenic arthritis of the adult knee employing wide open arthrotomy and early active motion, as well as synovectomy in some knees, was used in thirty-four patients with pyogenic arthritis of the knee. Of these patients, sixteen had a good result, twelve had a fair result, and six had a poor result. This method of treatment was used as a salvage procedure in most of the patients, but may have more general application in the treatment of pyogenic arthritis of the knee.
