Collaborating for Health: Health in All Policies and the Law
Authors: Pepin Dawn , Winig Benjamin D. , Carr Derek , Jacobson Peter D.
Published: July 2017

This article introduces and defines the Health in All Policies (HiAP) concept and examines existing state legislation, with a focus on California. The article starts with an overview of HiAP and then analyzes the status of HiAP legislation, specifically addressing variations across states. Finally, the article describes California's HiAP approach and discusses how communities can apply a HiAP framework not only to improve health outcomes and advance health equity, but also to counteract existing laws and policies that contribute to health inequities.
Employer Requirements to Work during Emergency Responses: Key Ethics Considerations
Authors: Rutkow Lainie , Taylor Holly A. , Powell Tia
Published: July 2017

Local health departments and their employees are at the forefront of emergency preparedness and response. Yet, recent studies have found that some local public health workers are unwilling to report to work in a variety of disaster scenarios. This can greatly compromise a response, as many local health departments need “all hands on deck” to effectively meet increased demands. To address these concerns, local health departments have employed varied policy strategies to ensure that employees do report to work. After describing different approaches taken by local health departments throughout the United States, we briefly identify and explore key ethics considerations that arise for local health departments when employees are required to report to work for emergency responses. We then discuss how these ethics considerations may inform local health department practices intended to promote a robust emergency response.
Health Care System Transformation and Integration: A Call to Action for Public Health
Authors: Wiley Lindsay F. , Matthews Gene W.
Published: July 2017

Restructured health care reimbursement systems and new requirements for nonprofit hospitals are transforming the U.S. health system, creating opportunities for enhanced integration of public health and health care goals. This article explores the role of public health practitioners and lawyers in this moment of transformation. We argue that the population perspective and structural strategies that characterize public health can add value to the health care system but could get lost in translation as changes to tax requirements and payment systems are rapidly implemented. We urge public health leaders to take a more active role in hospital assessments of community health needs and evaluation of the patient outcomes for which providers are accountable.
Heparin-Induced Thrombocytopenia: Historical Review
Authors: Messmore Harry L.
Published: July 2017

Heparin-induced thrombocytopenia (HIT) and heparin-induced thrombosis (HITT), recognized as clinical entities only in the past 30 years, have become a major concern for all who work in the field of thromboembolism, its prevention, and treatment. Studies of the 1930 to 1970 era were primarily devoted to the interaction of heparin with platelets in vivo with no knowledge that such interaction could lead to serious morbidity and mortality in as many as 3–5% of patients receiving the drug. When this was recognized in the 1970s, concerns arose regarding recognition and diagnoses. Clinicians, laboratory investigators, and drug companies entered into many research collaborations. The advent of low molecular weight heparin (LMWH) and heparinoids led to studies of their interaction with the IgG antibody that was identified as the mechanism for heparin-induced thrombocytopenia of the immune type. Newer, more sensitive test systems were developed and applied to studies comparing the new low LMWHs and heparinoids. These studies showed a lower incidence of immune-mediated thrombocytopenia with LMWH. The specificity of the antibody for platelet factor 4-heparin complexes led to the development of new tests in the early 1990s. This was soon followed by experiments with antithrombin drugs such as hirudin and argatroban as replacements for heparin in the HIT-HITT syndrome. Shorter courses of heparin therapy and the use of LMWH in place of heparin had become more standard practice in the 1990s.
Laboratory Diagnosis of Heparin-Induced Thrombocytopenia

Published: July 2017

The characteristics of the currently available platelet function assays (platelet aggregation, serotonin release, and flow cytometry) and enzyme-linked immunosorbent assays that quantitate antiheparin-platelet factor 4 antibody titers were studied using sera collected from clinically diagnosed heparin-induced thrombocytopenia patients, patients without heparin-induced thrombocytopenia, patients with platelet immune disorders other than heparin-induced thrombocytopenia, and normal individuals. The platelet aggregation assay was less sensitive than the serotonin release assay, which was less sensitive than the enzyme-linked immunosorbent assay ( p < 0.001). Yet heparin-induced thrombocytopenia was identified by platelet aggregation assay in cases where the serotonin release assay and/or the enzyme-linked immunosorbent assay were negative. Patients with heparin-induced thrombocytopenia and thrombosis were more often positive than heparin-induced thrombocytopenia patients without thrombosis ( p < 0.05). Positive platelet aggregation assay and serotonin release assay results were generally associated with a higher antibody titer; however, a minimum critical titer could not be identified. Over a 30-day period the percentage of positive responses did not change significantly even though clinical symptoms corrected in most heparin-induced thrombocytopenia patients. Multiple testing over several days enhanced the chance of detecting a positive, and combined results of the three assays further enhanced the positive response ( p < 0.005). In patients without heparin-induced thrombocytopenia, false-positive results were obtained with the enzyme-linked immunosorbent assay. These data demonstrate that there is no direct correlation between the positive responses of these assays, that clinically positive patients can be missed by all assays, and the presence of antibody alone does not determine clinical heparin-induced thrombocytopenia. With these limitations, the combination of aggregation, serotonin release, and enzyme-linked immunosorbent assay testing with multiple samples offers the best chance of identifying a positive heparin-induced thrombocytopenia patient. Caution is advised for all assays as none is optimal.
An analytical study on the free vibration of moderately thick fluid-infiltrated porous annular sector plates
Authors: Rezaei AS , Saidi AR
Published: July 2017

An exact analytical approach based on Mindlin plate theory is considered for free vibration analysis of fluid-saturated porous annular sector plates. The interconnected network of pores is saturated by inviscid fluid and the fluid is trapped in the network. The plate’s radial edges are considered to be simply supported and four auxiliary functions are used to evaluate the natural frequencies of porous plates under undrained condition. The mechanical properties of the material are considered to vary through the thickness by expressing shear modulus and density in terms of a simple cosine rule in case of plates with pores free of fluid. The present method is validated by comparing it with the results of other accurate solutions found in the literature. The influence of the coefficient of plate porosity, geometrical parameters as well as the effect of fluid on natural frequency response of porous annular sector plates under various boundary conditions are comprehensively investigated. It is found that the presence of fluid in the interconnected network of pores causes the fundamental natural frequency to increase. The method proposed in this paper may provide useful information for the future assessments of the dynamic response of porous structures when fluid–solid interaction effects are fully taken into account.
The Effects of Victim Age, Perceiver Gender, and Parental Status on Perceptions of Victim Culpability When Girls or Women Are Sexually Abused
Authors: Klettke Bianca , Mellor David , Hallford David
Published: July 2017

This study investigated perceptions of victim culpability in sexual assaults against girls and women according to victim age, perceiver gender, and perceiver parental status. Overall, 420 jury-eligible participants completed an online survey recording their attributions of guilt, responsibility, and blame toward 10-, 15-, and 20-year-old girls and women in relation to sexual assault. Attributions of culpability were affected by whether the victim physically or verbally resisted the abuse, wore sexually revealing clothes, or was described as having acted promiscuously. Fifteen-year-old victims were perceived as more culpable for the abuse than 10-year-old victims. Implications of these findings are discussed.
Why Shrinking Cities Are Not Mirror Images of Growing Cities: A Research Agenda of Six Testable Propositions
Authors: Galster George
Published: July 2017

I advance six propositions regarding the features of urban decline processes that distinguish them from those in growing cities. First, they are demographically selective, as population losses are disproportionately comprised of more advantaged households. Second, they are dynamically nonlinear, as population changes exceed thresholds where socially problematic behaviors and residential disinvestment jump sharply. Third, they are asymmetrically scalable for technological, financial, physical, and political reasons. Fourth, they are minimally controlled by traditional land-use policies of zoning and building permits. Fifth, they are informally decentralized, as individuals and groups supplement the atrophied local public sector with “do it yourself” activities. Sixth, they are psychologically conservative, as residents try to conserve threatened physical, social, and psychological resources. The article synthesizes extant theory and evidence from multiple disciplines, although ultimately the propositions are advanced as working hypotheses commanding varying degrees of support, which collectively comprise a research agenda for further investigation.
Prevalence study on potential drug–drug interaction in cancer patients in Piacenza hospital’s Onco-Haematology department
Authors: Vecchia Stefano , Orlandi Elena , Confalonieri Corrado , Damonti Enrico , Riva Alessandra , Sartori Alessia , Cavanna Luigi
Published: July 2017

Background

Cancer patients can be a human model of potential drug interactions. Usually they receive a large number of different medications, including antineoplastic agents, drugs for comorbid illness and medication for supportive care, however information about these interactions are fragmented and poor.

Objective

We assessed a prospective study to evaluate the prevalence of drug interaction among patients hospitalized in the Onco-Haematology department, Hospital of Piacenza.

Methods

Data on drugs administered for cancer, comorbidities, or supportive care were collected from different computerized prescription software in use in the department; we compared them with a database to focus on the co-administration of drugs. A literature review was performed to identify major potential drug interaction and to classify them by level of severity and by strengths of scientific evidence.

Results

In this study 284 cancer patients were enrolled; patients had taken an average of seven drugs on each day of therapy plus chemotherapeutic agents, we identified 67 potential drug interactions. At least 53 patients had one potential drug interaction. Of all potential drug interactions 63 were classified as moderate severity and only four as major. In 55 cases chemotherapeutic agents were involved in possible interactions with supportive care drugs, meanwhile in 12 cases the potential drug interactions were between supportive care drugs.

Conclusions

In our centre, thanks to a computerized prescription software, integrated with caution alarm in case of possible interaction, we had a lower rate of potential drug interactions than the one from literature. It is possible to improve the software integrating the alarm with the potential drug interactions between chemotherapy agents and supportive care drugs.
Loperamide and cardiac events: Is high-dose use still safe for chemotherapy-induced diarrhea?
Authors: de Lemos Mário L , Guenter Jolene , Kletas Victoria
Published: July 2017

High-dose loperamide is often used for the acute management of chemotherapy-induced diarrhea, with a maximum daily dosing of up to 24 mg. Recently, the US Food and Drug Administration has issued a warning that loperamide can cause rare serious cardiac events, including QT prolongation, torsades de pointes, cardiac arrest and death. Most events were reported in patients taking very high doses for an extended period of time. Daily intake ranged from 64 mg to 1600 mg, often continuously for weeks or months. In addition, the reported serum levels of loperamide ranged from 22 ng/mL to 210 ng/mL, which is likely significantly higher than that expected from patients taking the recommended doses for chemotherapy-induced diarrhea. Overall, the incidence of serious cardiac events associated with loperamide remains low. In balance, the risk of uncontrolled complications from chemotherapy-induced diarrhea is likely greater than the rare cardiac risk associated with the chronic misuse of much higher doses of loperamide.
Ibrutinib-associated tumor lysis syndrome in chronic lymphocytic leukemia/small lymphocytic lymphoma and mantle cell lymphoma: A case series and review of the literature
Authors: Titus-Rains Krystal S , Brown Jamie N , Hammond Julia M
Published: July 2017

Background

Tumor lysis syndrome results when intracellular contents are released during cell lysis. Ibrutinib, a Bruton tyrosine kinase inhibitor, is used for the treatment of chronic lymphocytic leukemia, small lymphocytic lymphoma, Waldenström’s macroglobulinemia, mantle cell lymphoma, and marginal zone lymphoma. Tumor lysis syndrome caused by ibrutinib therapy is potentially life threatening, but is rare and not often reported in clinical trials.

Objective

The purpose of this case series is to describe the occurrence of tumor lysis syndrome in two patients initiated on ibrutinib, and to highlight the importance of close monitoring during therapy.

Discussion

One patient with chronic lymphocytic leukemia/small lymphocytic lymphoma and one patient with mantle cell lymphoma developed laboratory and clinical tumor lysis syndrome following initiation of ibrutinib therapy. Assessment with the Naranjo Adverse Drug Reaction Probability Scale indicated one probable relationship and one possible relationship between ibrutinib therapy and tumor lysis syndrome. There were additional factors that may have confounded the laboratory and clinical factors observed, including baseline laboratory values and concurrent medications. Both patients were managed with supportive therapies. A literature review identified five additional reported cases of tumor lysis syndrome following ibrutinib therapy.

Conclusion

This case series identifies one patient with a probable relationship and one patient with a possible relationship between the development of tumor lysis syndrome and treatment with ibrutinib. Although uncommon, proper attention should be given to monitoring for this adverse drug reaction and appropriate follow-up should occur despite ibrutinib’s ease of administration.
On the motion of a gyro in the presence of a Newtonian force field and applied moments
Authors: Amer T S , Abady I M
Published: July 2017

This work focuses on the motion of a dynamical model that consists of a symmetric rigid body (gyro) that rotates about a fixed point similar to Lagrange’s gyroscope. This body is acted upon by external forces represented by a Newtonian force field, gyro torques about the principal axes of inertia of the gyro and perturbing moments acting on the same axes. Assuming that, the gyro initially has a high angular velocity about the dynamic axis of symmetry. The averaging technique is used to obtain a more appropriate averaging system for the governing system of equations of motion in terms of a small parameter. Therefore, the analytical solutions of this system for two applications, depending on different forms of perturbing moments, are presented. These solutions are represented graphically to clarify the effectiveness of the different parameters of the body on the motion.

Published: July 2017

Mendelian susceptibility to mycobacterial disease is a rare syndrome characterized by severe clinical infections usually caused by weakly virulent mycobacterial species such as Bacillus Calmette-Guérin vaccines and environmental nontuberculous mycobacteria or more virulent mycobacteria as mycobacterium tuberculosis. Since 1996, 9 genes including 7 autosomal ( STAT1, IFNGR1, IFNGR2, IL12B, IL12RB1, ISG15, and IRF8) and 2 X-linked genes ( NEMO and CYBB) have been identified. Allelic heterogeneity leaded to recognize about 18 genetic diseases with variable clinical phenotypes, but sharing a same physiological mechanism represented by a defect in human IL-12-dependant-INF-γ-mediated immunity. We report here a case of multifocal Bacillus Calmette-Guérin osteomyelitis in a context Mendelian susceptibility to mycobacterial disease mimicking a metastatic neuroblastoma in a child presenting with delayed growth. The investigation of her twin sister showed the same disease. A heterozygous mutation in exon 22 of STAT1 gene was found in both sisters, another sister and the father being healthy and heterozygous for the same mutation.
Pediatric Xanthogranulomatous Cystitis
Authors: Preece Janae , Prasad Vinay , McLeod Daryl
Published: July 2017

Xanthogranulomatous cystitis (XC) is a rare condition affecting the bladder thought to be caused by chronic inflammation. Fewer than 30 cases have been reported in the literature since being first described in 1932. We present the first reported case of XC in a pre-pubertal male and review the literature. A 10-year-old boy presenting with dysuria subsequently developed frequency. After failure of conservative management, an ultrasound of the bladder revealed a mass. The patient underwent partial cystectomy. Pathology showed XC. At 10 months postoperatively, the patient remained asymptomatic and without evidence of recurrence.
Chorionic Histiocytic Hyperplasia is Associated With Chronic Inflammatory Lesions in the Placenta
Authors: Katzman Philip J , Metlay Leon A , McMahon Loralee A , LiQiong Li , Zhang Bin
Published: July 2017

Background

Chorionic histiocytic hyperplasia (CHH) is a cellular proliferation at the base of the chorion that was identified by the authors in examining placentas for chronic chorioamnionitis (CC). This study is a retrospective review of cases diagnosed with CHH, describing its incidence alone and with associated lesions, and the immunophenotype of lesional cells.

Design

In this retrospective study, a laboratory information system search over a 34-month period using the key phrase “chorionic stromal” was performed. Cases identified were reviewed for presence of the following: CC, chronic villitis (CV), chronic deciduitis (CD), maternal (MIR), and fetal (FIR) acute inflammatory responses, meconium deposition; and whether CD3 immunostaining was performed. Incidences were tabulated and compared with known prevalences in our population. Select cases were stained with various immunostains to identify cell lineage and X and Y fluorescent probes to identify fetal or maternal cell origin in cases with male infants.

Results

Eighty cases of CHH were identified during the study period. Incidences of inflammatory lesions associated with CHH were: CV (54/80, 68%), CD (32/80, 40%), CC (25/80, 31%), MIR (39/80, 49%), and FIR (9/80, 11%). Only chronic inflammatory lesions had a significant correlation with the co-incidence of CHH. CC was identified alongside CHH in 12 of 22 cases in which a CD3 immunostain was performed. The cell population in CHH was vimentin+, CD68+, CD3−, CD45−, CD56−, hPL−, SMA−, OCT 3/4− and, in some cases, variably mixed with CD3+ lymphocytes. The cells had a male genotype by fluorescent in situ hybridization analysis.

Conclusion

The association of CHH with acute and chronic inflammatory conditions and its immunophenotype suggest that it may be a reactive process. CD3 immunostaining is helpful to identify concurrent CC.
Music Listening Among Postoperative Patients in the Intensive Care Unit: A Randomized Controlled Trial with Mixed-Methods Analysis
Authors: Ames Nancy , Shuford Rebecca , Yang Li , Moriyama Brad , Frey Meredith , Wilson Florencia , Sundaramurthi Thiruppavai , Gori Danelle , Mannes Andrew , Ranucci Alexandra , Koziol Deloris , Wallen Gwenyth R
Published: July 2017

Background:

Music listening may reduce the physiological, emotional, and mental effects of distress and anxiety. It is unclear whether music listening may reduce the amount of opioids used for pain management in critical care, postoperative patients or whether music may improve patient experience in the intensive care unit (ICU).

Methods:

A total of 41 surgical patients were randomized to either music listening or controlled non-music listening groups on ICU admission. Approximately 50-minute music listening interventions were offered 4 times per day (every 4-6 hours) during the 48 hours of patients’ ICU stays. Pain, distress, and anxiety scores were measured immediately before and after music listening or controlled resting periods. Total opioid intake was recorded every 24 hours and during each intervention.

Results:

There was no significant difference in pain, opioid intake, distress, or anxiety scores between the control and music listening groups during the first 4 time points of the study. However, a mixed modeling analysis examining the pre- and post-intervention scores at the first time point revealed a significant interaction in the Numeric Rating Scale (NRS) for pain between the music and the control groups ( P = .037). The Numeric Rating Score decreased in the music group but remained stable in the control group. Following discharge from the ICU, the music group’s interviews were analyzed for themes.

Conclusions:

Despite the limited sample size, this study identified music listening as an appropriate intervention that improved patients’ post-intervention experience, according to patients’ self-report. Future mixed methods studies are needed to examine both qualitative patient perspectives and methodology to improve music listening in critical care units.
Primary Cutaneous Peripheral T-Cell Lymphoma in a Sporotrichoid Pattern: A Case Report
Authors: Lewis Daniel J. , Vin Harina , Hinojosa Tiffany , Tetzlaff Michael T. , Dabaja Bouthaina S. , Duvic Madeleine
Published: July 2017

We present the extraordinary case of a 72-year-old man with a history of primary cutaneous peripheral T-cell lymphoma not otherwise specified (pcPTCL-NOS) previously controlled with topical agents who developed tumours in a sporotrichoid pattern. Culture of the tumours was negative, and histopathology showed findings consistent with recurrent pcPTCL. The tumours were successfully treated with localised radiation therapy. Sporotrichoid lesions are an extremely rare and atypical presentation of cutaneous lymphoma, with only 2 other cases reported in the literature. Our case reinforces the need to include cutaneous lymphoma in the differential diagnosis of nodules on the extremities spreading in a sporotrichoid pattern. Clinical recognition of this atypical presentation of cutaneous lymphoma allows for prompt, effective treatment, which might include localised radiation therapy.
We beat the cops in GTA: Po(ludic)al activism in the age of video games
Authors: Demirbag-Kaplan Melike , Kaplan-Oz Begum
Published: July 2017

This article explores how individuals reflect on their digital experiences of actualizing fantasies to make sense of their everyday actions, particularly in the context of video gaming. Our study takes a qualitative approach to understanding the context of materializing consumer fantasies, as initially experienced and actualized in video games, and how these fantasies are transformed into material reality, through an investigation of an illustrative case of mass street protests, the 2013 Gezi Protests in Turkey. The findings suggest that digital virtual experiences in video games have obvious manifestations in the material world, as consumers travel on the borders of reality, moving back and forth into the liminoid terrain of the digital virtual, and provide a deeper understanding of how the blurred boundaries between the virtual and material are established in practice.
Conceptualizing media users across media
Authors: Picone Ike
Published: July 2017

Many academic works and authors have added to our understanding of the changing audience dynamics that emerged with the wide adoption of digital media by exploring audiences turning into prosumers, producers, pro-ams and so on. Gradually, and rather unnoticed, another denominator seems to have entered our academic vocabulary: the user. Although widely adopted, many media scholars remain wary of this notion, as it would undermine theoretical advancements made in audience studies. At the same time, the almost natural adoption of the term in media studies indicates that ‘user’ is at least intuitively better suited than ‘audience’ to address people in relationship with media today. The article makes the case for ‘media user’ and ‘media use’ as not merely suitable terms but also as more encompassing analytical concepts, especially in light of understanding cross-media use. First, an argumentation is developed for adopting these terms by showing the analytical benefits of talking about media users when addressing people ‘floating’ across media. Subsequently, the notion of media use is grounded in both traditional approaches and recent advancements in media studies. Special attention is given to the notion of audience activity and how it translates into a cross-media environment. The article concludes with a critical reflection on both terms in relation to notions such as participation and user empowerment.
A sociocultural approach to study public connection across and beyond media
Authors: Hovden Jan Fredrik , Moe Hallvard
Published: July 2017

This article presents an approach to cross-media use analysis suited to answering the question of how citizens from different sociocultural groups experience their freedom of information. The approach is based on normative democratic theory, is attentive to the dimensions of culture and media that lie beyond a predefined political dimension and is designed to analyse, from a citizen’s perspective, how people experience a public world in which shared problems are addressed. To illustrate the approach, the article draws on the analysis of two empirical examples: one of a representative sample of the Norwegian citizenry ( N = 3660) and one of Norwegian students ( N = 1223). We conduct latent class analysis as well as multiple correspondence analysis to help improve our understanding of the consequences of fragmented and personalized media use by shedding light on the implications of changing patterns of public connection.
The materiality of the intangible: Literary metaphor in multimodal texts
Authors: Skains R Lyle
Published: July 2017

Based on a larger practice-based research project in digital writing, this article examines how the materiality of digital media contributes to a layered metaphor that delivers meaning, reflects on the cognitive processes (the writer’s and the reader’s) of navigation and generates a dynamic narrative structure through multimodality, unnatural narration and user interaction. Many writers and artists engage with their chosen medium through an instinctive understanding of the materials at hand, gained through experience; the explicit study of a medium’s materiality is not always required for artistic success, however, that may be judged. This article offers insights into the creative process of creating digital, multimodal fiction, based on a practice-based research project designed to explore the effects of digital media on author and text, and argues that digital media have a significant effect on the outcome of the artefact itself. Awareness of these effects, their variations according to hardware and software, and the affordances of these various materials offer the digital writer greater insight and capability to craft his/her texts for the desired metaphorical meaning.
Empathy at play: Embodying posthuman subjectivities in gaming
Authors: Wilde Poppy , Evans Adrienne
Published: July 2017

In this article, we address the need for a posthuman account of the relationship between the avatar and player. We draw on a particular line of posthumanist theory associated closely with the work of Karen Barad, Rosi Braidotti and N. Katherine Hayles that suggests a constantly permeable, fluid and extended subjectivity, displacing the boundaries between human and other. In doing so, we propose a posthuman concept of empathy in gameplay, and we apply this concept to data from the first author’s 18-month ethnographic field notes of gameplay in the MMORPG World of Warcraft. Exploring these data through our analysis of posthuman empathy, we demonstrate the entanglement of avatar–player, machine–human relationship. We show how empathy allows us to understand this relationship as constantly negotiated and in process, producing visceral reactions in the intra-connected avatar–player subject as well as moments of co-produced in-game action that require ‘affective matching’ between subjective and embodied experiences. We argue that this account of the avatar–player relationship extends research in game culture, providing a horizontal, non-hierarchical discussion of its most necessary interaction.
Building the ‘Truthmeter’: Training algorithms to help journalists assess the credibility of social media sources
Authors: Fletcher Richard , Schifferes Steve , Thurman Neil
Published: July 2017

Social media is now used as an information source in many different contexts. For professional journalists, the use of social media for news production creates new challenges for the verification process. This article describes the development and evaluation of the ‘Truthmeter’ – a tool that automatically scores the journalistic credibility of social media contributors in order to inform overall credibility assessments. The Truthmeter was evaluated using a three-stage process that used both qualitative and quantitative methods, consisting of (1) obtaining a ground truth, (2) building a description of existing practices and (3) calibration, modification and testing. As a result of the evaluation process, which could be generalized and applied in other contexts, the Truthmeter produced credibility scores that were closely aligned with those of trainee journalists. Substantively, the evaluation also highlighted the importance of ‘relational’ credibility assessments, where credibility may be attributed based on networked connections to other credible contributors.
Videoconferencing for Continuing Medical Education: From Pilot Project to Sustained Programme
Authors: Allen Michael , Sargeant Joan , MacDougall Eileen , Proctor-Simms Michelle
Published: July 2017

Videoconferencing has been used to provide distance education for medical students, physicians and other health-care professionals, such as nurses, physiotherapists and pharmacists. The Dalhousie University Office of Continuing Medical Education (CME) has used videoconferencing for CME since a pilot project with four sites in 1995–6. Since that pilot project, videoconferencing activity has steadily increased; in the year 1999–2000, a total of 64 videoconferences were provided for 1059 learners in 37 sites. Videoconferencing has been well accepted by faculty staff and by learners, as it enables them to provide and receive CME without travelling long distances. The key components of the development of the videoconferencing programme include planning, scheduling, faculty support, technical support and evaluation. Evaluation enables the effect of videoconferencing on other CME activities, and costs, to be measured.
Sleep and psychiatric symptoms in young child psychiatric outpatients
Authors: Huhdanpää Hanna , Klenberg Liisa , Westerinen Hannu , Fontell Tuija , Aronen Eeva T
Published: July 2017

Background:

Sleep may underlie psychiatric symptoms in young children. However, not many studies have reported on sleep and its associations with symptoms in young child psychiatric patients.

Objectives:

To assess the amount and quality of sleep and how sleep associates with psychiatric symptoms in young child psychiatric patients. Furthermore, we evaluated how sleep and daytime somnolence differed in patients and their age- and gender-matched controls.

Method:

The sample consisted of 139 3- to 7-year-old child psychiatric outpatients and 139 age- and gender-matched controls from community. We evaluated sleep and daytime somnolence with the Sleep Disturbance Scale for Children in all children and psychiatric symptoms with Child Behaviour Checklist (CBCL) in the patient group. Family background information was collected from the patients.

Results:

Of the patients, 31.6% had a significant sleep problem and 14.4% slept too little. The most typical sleep problems were restless sleep (31.7%), morning tiredness (21.6%) and difficulties getting to sleep at night (18.7%). All types of sleep problems were associated with CBCL total, internalising and externalising problems (all p-values < .01). We observed a strong association between all types of sleep problems and emotionally reactive subscale ( p-value < .001). Furthermore, parent-reported sleep problems increased significantly the risk of having high scores on total (odds ratio (OR) = 5.3, 95% confidence interval (CI) = [2.2, 12.6], p < .001), external (OR = 3.7, 95%, CI = [1.6, 8.5], p < .01) and internal (OR = 2.5, 95% CI = [1.1, 5.5], p < .05) scores after controlling for age, gender, family structure and parent’s educational level. Even mild sleep disturbance increased the intensity of psychiatric symptoms. Compared to controls, patients slept less ( p < .001) and had significantly more frequent restless sleep, nightmares and morning and daytime somnolence.

Conclusion:

Sleep problems and too little sleep are prevalent in young child psychiatric patients, and they relate strongly to the intensity of psychiatric symptoms. Identification and treatment of sleep problems should be a routine part of the treatment plan for young child psychiatric patients. The results emphasise the need for assessing sleep in young child psychiatric patients, as treating the sleep problem may reduce psychiatric symptoms.
Oral and written language abilities in young Spanish/English bilinguals
Authors: Ardila Alfredo , Rosselli Mónica , Ortega Alexandra , Lang Merike , Torres Valeria L
Published: July 2017

Purpose:

The purpose of this study was to compare oral and written language abilities in English and Spanish of young bilinguals residing in the USA.

Methodology:

Sixty-two participants (mean age = 23.7; SD = 3.50), consisting of 42 bilinguals (born of Spanish-speaking parents) and 20 English monolinguals, were administered a battery of 15 language tasks.

Analysis:

Bilinguals were divided into two groups: (a) US-born (simultaneous bilinguals who had been exposed to English and Spanish since birth and educated primarily in English) and (b) Latin American-born (early sequential bilinguals who were educated in Spanish and English, although exposed to Spanish at birth and to English before the age of 10).

Findings:

Higher lexical ability was demonstrated in English compared to Spanish in bilinguals. Performance in grammar tests of the two languages was inconsistent. Reading/writing ability in English was similar for participants born in the USA and in Latin America; however, participants who were born in Latin America had significantly higher scores for Spanish reading/writing tasks. When comparing performance in English tests, it was found that scores for bilingual participants were similar to those of English monolinguals.

Originality:

The current study directly compares oral and written language abilities in two subgroups of young Spanish/English bilinguals. Three language dimensions are studied: lexicon/grammar; oral/written language; and language knowledge/language use.

Implications:

Our results suggest that bilingualism does not interfere with normal linguistic ability in English.

Limitations:

The current study was carried out in a specific bilingual context. Generalization of these results should be done with caution.
Health complaints in late adolescence; Frequency, factor structure and the association with socio-economic status
Authors: Myrtveit Sæther Solbjørg Makalani , Sivertsen Børge , Haugland Siren , Bøe Tormod , Hysing Mari
Published: July 2017

Aims: Little is known about social disparities in health in late adolescence. Among boys and girls aged 17–19, we aimed to (1) describe frequency of health complaints, (2) investigate the factor structure of health complaints and (3) examine the association between health complaints and socio-economic status (SES). Methods: Data from the large population-based youth@hordaland survey ( n=10,253) were used. Health complaints were assessed by five items from the Health Behaviour in School-Aged Children Symptoms Checklist, SES by parental education and perceived family economy. Associations between health complaints and SES were investigated using analysis of variance, and the factor structure of health complaints using confirmatory factor analyses. Results: At least one weekly complaint was reported by 47% of girls and 21% of boys. The items showed a good fit to a simple one-factor model when back pain and neck/shoulder pain were allowed to correlate. Health complaints were more frequent among adolescents reporting poor perceived family economy and lower parental education. Conclusions: Our results suggest that health complaints are common in adolescence and might, as in adults, be part of everyday life. Health complaints are more frequent among adolescents from families with lower SES.

Objectives: The 10-item Connor-Davidson Resilience Scale (CD-RISC 10) is a brief instrument measuring resilience in adults. The scale has shown sound psychometric properties in different populations and cultures. Our objectives were to cross-culturally adapt the CD-RISC 10 into Danish and to establish the psychometric properties of the Danish version in terms of internal consistency, construct validity and longitudinal validity. Methods: The CD-RISC 10 was translated using established guidelines. Employees ( N=272) at hospitals in the Central Denmark Region completed questionnaires at baseline and three months follow-up. Questionnaires included the translated Danish version of the CD-RISC 10 and the 10-item Perceived Stress Scale (PSS-10). Internal consistency was assessed by Cronbach’s alpha and construct and longitudinal validity by correlating CD-RISC 10 and PSS-10 baseline scores and change scores from baseline to follow-up. Results: The Danish CD-RISC 10 provides acceptable internal consistency (Cronbach’s alpha = 0.87). Analysis of construct validity revealed a negative correlation with the PSS-10 at baseline ( r=−.63 [95%CI: −.70; −.55], p<.0001). Analysis of longitudinal validity similarly demonstrated a negative correlation on change scores from baseline to follow-up ( r=−.51 [95%CI: −.62; −.39], p<.0001). Conclusions: The scale has acceptable psychometric properties as an instrument for measuring resilience in a Danish-speaking population.
Social antecedents and consequences of political privacy
Authors: Park Yong Jin
Published: July 2017

Using a national sample in the United States ( n = 1047), we test the social stratification of (1) political disclosure and (2) its effects on one’s decision to connect into and disconnect from communities, as indicated by friendship or follower status. The analysis poses larger questions about the function of social media in bringing together diverse communities and explores how one’s political disclosure is (1) affected by social backgrounds and (2) affects the characteristic of mediated social interactions. We found that political disclosure and racial background had the interactive relationship in influencing one’s social connection. Frequent social media use, on the other hand, was not associated with the disclosure of political viewpoints. We discuss the implications of how socialization might incubate the differential effects among social segments, as well as the mixed effects of social media on the users from different communities.
How do I hold this thing? Controlling reconstructed Q*berts
Authors: Hodges James A
Published: July 2017

Preserving a historically significant video game frequently requires either preserving or adapting a touchable interface for contemporary use. While control techniques are often evaluated in terms of fidelity between in- and out-of-game actions, this essay emphasizes several ways that fidelity must be actively constructed. Bringing a haptic perspective on video gaming into conversation with game history and preservation, this essay examines ways that textual materials surrounding and supplementing a work can be used to construct haptic fidelity. The video game Q*bert is selected as a case study both because of its historical and cultural significance and because it makes idiosyncratic use of controller and force-feedback technologies. The essay concludes that playing Q*bert in a preservation setting requires several unique accommodations at the level of touchable interface, and each accommodation illustrates another way that supplementary texts help construct historical haptic fidelity.
Haptic media and the cultural techniques of touch: The sphygmograph, photoplethysmography and the Apple Watch
Authors: O’Neill Christopher
Published: July 2017

This article draws upon cultural techniques theory to propose an approach to studying haptic media as media technologies which train or discipline touch and which serve to produce touch itself as a coherent and ‘proper’ communicative technology. This article analyses the different forms of touch which have coalesced around the sphygmograph, a nineteenth-century pulse writing technology, and photoplethysmography, a contemporary heart rate–measuring technology which has been remediated as part of the Apple Watch. This article demonstrates that nineteenth-century clinicians drew upon the sphygmograph to authorise doctorly touch as newly ‘proper’ within a changed technological context. By contrast, an analysis of the place of error within the Apple Watch’s photoplethysmograph demonstrates how contemporary self-quantifiers are encumbered with an unreliable measuring apparatus which can only generalise a form of ‘improper’ touch, touch which fails to know the body and which remains tied to a ‘proper’ touch which lies elsewhere.
What a difference training can make: Impacts of targeted training on journalists, journalism educators and journalism students’ knowledge of Islam and Muslims
Authors: Ewart Jacqui , O’Donnell Kate , Chrzanowski April
Published: July 2017

The problematic nature of news media framing of Islam and Muslims by Western news media has been well established by researchers. While research has focused on the ways such representations occur and to a lesser extent their effects on individuals and communities, we know little about why journalists frame Islam and Muslims in the Western news media in the ways they do. While studies point to a lack of knowledge about Islam and Muslims in non-Muslim populations, we know very little about how this translates to news media practitioners. This study draws from a far broader research project focused on encouraging more informed reporting of Islam and Muslims by the Australian news media. In this study, we establish the baseline knowledge of a purposive sample of Australian news media practitioners and journalism students about Islam and reporting stories about Islam and Muslims before and after targeted training. We find a relatively small investment in time significantly shifts this knowledge in both areas. Targeted training that includes a focus on basic facts about Islam as well as raising awareness of the resources that are now available to journalists may go some way towards improving reportage of Islam and Muslims.
The role of the government in the development of the automobile industry in Korea

Published: July 2017

This article addresses the effect of government R&D policies on the development of Korea’s automobile industry, particularly in relation to technological upgrading. The automobile industry is a highly value-added, technology-intensive industry that generates many good job opportunities. In addition, it is linked to various industries. Korea developed its own car model in the mid-1970s and since then Korea’s automobile industry has continued to develop. Effective government policies have played a significant role in its remarkable success. This article provides policy suggestions for developing countries intending to develop their own automobile industries.
Projected Improvements in Accelerated Partial Breast Irradiation Using a Novel Breast Stereotactic Radiotherapy Device: A Dosimetric Analysis

Accelerated partial breast irradiation has caused higher than expected rates of poor cosmesis. At our institution, a novel breast stereotactic radiotherapy device has demonstrated dosimetric distributions similar to those in brachytherapy. This study analyzed comparative dose distributions achieved with the device and intensity-modulated radiation therapy accelerated partial breast irradiation. Nine patients underwent computed tomography simulation in the prone position using device-specific immobilization on an institutional review board–approved protocol. Accelerated partial breast irradiation target volumes (planning target volume_10mm) were created per the National Surgical Adjuvant Breast and Bowel Project B-39 protocol. Additional breast stereotactic radiotherapy volumes using smaller margins (planning target volume_3mm) were created based on improved immobilization. Intensity-modulated radiation therapy and breast stereotactic radiotherapy accelerated partial breast irradiation plans were separately generated for appropriate volumes. Plans were evaluated based on established dosimetric surrogates of poor cosmetic outcomes. Wilcoxon rank sum tests were utilized to contrast volumes of critical structures receiving a percentage of total dose ( Vx). The breast stereotactic radiotherapy device consistently reduced dose to all normal structures with equivalent target coverage. The ipsilateral breast V20-100 was significantly reduced ( P < .05) using planning target volume_10mm, with substantial further reductions when targeting planning target volume_3mm. Doses to the chest wall, ipsilateral lung, and breast skin were also significantly lessened. The breast stereotactic radiotherapy device’s uniform dosimetric improvements over intensity-modulated accelerated partial breast irradiation in this series indicate a potential to improve outcomes. Clinical trials investigating this benefit have begun accrual.
