CBCT image guidance in head and neck irradiation: the impact of daily and weekly imaging protocols
Authors: Nyarambi Innocencia , Chamunyonga Crispen , Pearce Andrew
Published: June 2015

Purpose

This study evaluated the impact of a daily and weekly image-guided radiotherapy protocols in reducing setup errors and setting of appropriate margins in head and neck cancer patients.

Materials and methods

Interfraction and systematic shifts for the hypothetical day 1–3 plus weekly imaging were extrapolated from daily imaging data from 31 patients (964 cone beam computed tomography (CBCT) scans). In addition, residual setup errors were calculated by taking the average shifts in each direction for each patient based on the first three shifts and were presumed to represent systematic setup error. The clinical target volume (CTV) to planning target volume (PTV) margins were calculated using van Herk formula and analysed for each protocol.

Results

The mean interfraction shifts for daily imaging were 0·8, 0·3 and 0·5 mm in the S-I (superior-inferior), L-R (left-right) and A-P (anterior-posterior) direction, respectively. On the other hand the mean shifts for day 1–3 plus weekly imaging were 0·9, 1·8 and 0·5 mm in the S-I, L-R and A-P direction, respectively. The mean day 1–3 residual shifts were 1·5, 2·1 and 0·7 mm in the S-I, L-R and A-P direction, respectively. No significant difference was found in the mean setup error for the daily and hypothetical day 1–3 plus weekly protocol. However, the calculated CTV to PTV margins for the daily interfraction imaging data were 1·6, 3·8 and 1·4 mm in the S-I, L-R and A-P directions, respectively. Hypothetical day 1–3 plus weekly resulted in CTV–PTV margins of 5, 4·2 and 5 mm in the S-I, L-R and A-P direction.

Conclusions

The results of this study show that a daily CBCT protocol reduces setup errors and allows setup margin reduction in head and neck radiotherapy compared to a weekly imaging protocol.

Authors: Crossman Sue , Pfeil Michael , Moore Jennifer , Howe Amanda
Published: June 2015

Aim

The aim of this study was to explore the factors affecting role development in practice nursing in the United Kingdom.

Background

General practice is currently central to National Health Service reform, producing favourable conditions for the practice nurse role to be further strengthened and developed. However, the literature has continued to describe evidence that practice nurses are a disempowered, isolated group with many constraints reducing their ability to respond to opportunities to develop their role. The rationale for conducting the study was therefore to provide a greater understanding about the constraining factors and their influence on practice nurses wishing to develop their role.

Method

The method used to conduct the research followed a case approach, as the subject being investigated was complex with multiple inter-related factors and the approach was exploratory. The cases comprised six UK general practices and the participants within each case were a practice nurse, a GP and a practice manager.

Findings

A combination of factors was found to contribute to the way the practice nurse role evolves. These are education, practice culture, practice nurse personal characteristics and empowerment. Empowerment holds the key to maximising the conditions favourable to practice nurse role evolution. This is not, however, a ‘single’ factor; it represents the combined synergistic effects of practice culture and practice nurse personal characteristics on creating an empowering environment. The inter-relationship between these was captured in a framework and given the title ‘empowering employment principles’.

Conclusion

The ‘empowering employment principles’ illustrate the features most conducive to role evolution, thus providing a tool for practice nurses and their employers to enhance opportunities for nurses to develop their role.

Published: June 2015

This exploratory study aims to understand and improve the performance of Gambia Indigenous Livestock Multipliers’ Associations (GILMA – Fulladu and Saloum) as a way of enabling them to better respond to the challenges faced in fulfilling their institutional responsibilities. Using participatory institutional diagnosis, the GILMA members and experts were able to examine their associations and to stimulate collective reflection as a means of making the associations more efficient and effective. The findings of this diagnosis showed that functioning of both GILMAs was closely linked to the operations of their technical partners. This resulted to GILMAs which clearly lack defined vision and mission. Main issues to address include capacity development of GILMA's executive committee in terms of institutional management, group facilitation, participatory planning, effective strategies for partnership and ownership. Overall, this study developed pathways for revitalizing GILMAs into vibrant and self-sustaining indigenous ruminant livestock multipliers’ associations that can effectively carry out specific roles and responsibilities within the three-tier Open Nucleus Breeding Scheme of the International Trypanotolerance Centre.

Authors: Isensee Barbara , Maruska Karin , Hanewinkel Reiner
Published: June 2015

Zielsetzung: Untersuchung der langfristigen Auswirkungen des für die Grundschule konzipierten Präventionsprogramms Klasse2000 auf den Substanzkonsum. Methodik: Klasse2000 will mittels interaktiver Methoden die Lebenskompetenzen fördern und zu einem gesunden Lebensstil motivieren. Die Daten wurden in schriftlichen Nachbefragungen einer Kontrollgruppenstudie mit Messwiederholung 16 Monate (N = 501, mittl. Alter 11,4 Jahre, 43,7 % männlich) und 36 Monate (N = 408, mittl. Alter 12,9 Jahre, 43,1 % männlich) nach Ende der Intervention gewonnen. Die Zuteilung zu den Gruppen erfolgte in der Ursprungsstudie auf Ebene der Schulen unter Berücksichtigung der Präferenz der Schulen. Ergebnisse: In beiden Nachbefragungen waren Lebenszeitprävalenz und Inzidenz des Rauchens in der Interventionsgruppe statistisch bedeutsam geringer als in der Kontrollgruppe. Beim Alkoholkonsum konnte nur in der ersten Nachbefragung eine signifikant geringere Lebenszeitprävalenz in der Interventionsgruppe gefunden werden. In der zweiten Nachbefragung war in der Untergruppe derjenigen Jugendlichen, die bereits Alkohol konsumiert hatten, in der Interventionsgruppe die Intensität des Alkoholkonsums geringer als in der Kontrollgruppe. Schlussfolgerungen: 16 bzw. 36 Monate nach Abschluss der Intervention finden sich Hinweise auf präventive Effekte des Programms Klasse2000 auf das Rauchverhalten. Für den Alkoholkonsum ist die Befundlage weniger überzeugend.
Kontrolliertes Trinken bei Alkoholkonsumstörungen: Eine systematische Übersicht
Authors: Körkel Joachim
Published: June 2015

Hintergrund: Verhaltenstherapeutische Behandlungen zum selbstkontrollierten Trinken (KT) wurden in den letzten 50 Jahren vielfältig erforscht. Eine aktuelle Übersicht über den gegenwärtigen Status dieses Ansatzes liegt nicht vor. Fragestellung: Es wird ein systematischer Überblick über die Konzept- und Forschungsgeschichte des KT (Definition, theoretische Wurzeln, Behandlungsmethoden), Wirksamkeit von KT-Behandlung (inkl. Prognosefaktoren) sowie Implementierung von KT in das Behandlungssystem (Akzeptanz und Verbreitung) vorgenommen. Methodik: Gemäß den PRISMA Richtlinien wurde in den Datenbanken PsycINFO, Medline und Psyndex nach psychologischen Behandlungen zum selbstkontrollierten Alkoholkonsum bei Menschen mit klinisch relevanten Alkoholproblemen recherchiert und 676 einschlägige Beiträge identifiziert. Ergebnisse: KT wird als regelgeleitet-planvoller Alkoholkonsum definiert. Seine theoretischen Wurzeln reichen von Lerntheorien bis zur Psychologie der Selbstregulation. In der Behandlung haben Behavioral Self-Control Trainings frühere Methoden (z. B. aversive Konditionierung, Kontingenzmanagement und Reizexposition) abgelöst. Einzel und Gruppenbehandlungen sowie Selbsthilfemanuale zum KT erweisen sich über das gesamte Spektrum des problematischen Alkoholkonsums als kurz- und langfristig wirksam zur Reduktion des Alkoholkonsums und alkoholassoziierter Probleme wie auch zur Förderung des Übergangs zur Abstinenz. Prognostisch bedeutsam sind v. a. der Zielentscheid des Patienten pro KT und seine Zuversicht in die Realisierbarkeit von KT. Akzeptanz und Verbreitung von KT haben in den letzten Jahrzehnten zugenommen und variieren u. a. länderspezifisch. Schlussfolgerungen: Angesichts der Wirksamkeit von KT-Behandlungen sowie gesundheitspolitischer, ethischer, therapeutischer und ökonomischer Überlegungen sollten Reduktionsbehandlungen gleichrangig neben Abstinenzbehandlungen in ein zieloffen ausgerichtetes Behandlungssystem integriert werden.
Inklusion – kinder- und jugendpsychiatrische Aspekte
Authors: Warnke Andreas
Published: June 2015

Seit März 2009 ist die Behindertenrechtskonvention der Vereinten Nationen (UN-BRK) Recht in Deutschland. «Inklusion» ist der zentrale Begriff. Allen Menschen mit gleich welcher Beeinträchtigung soll gleichberechtigt volle Teilhabe an der Gesellschaft ermöglicht werden. Inklusion setzt ethische, rechtliche, administrative, konzeptionelle, strukturelle, wirtschaftliche und so auch gesundheitspolitische Anpassungen der Gesellschaft voraus, sodass die individuelle Behinderung einer jeden Person so weit als nur möglich keine Alltagsbeeinträchtigung mehr darstellt. Die Übersichtsarbeit skizziert zunächst gesellschaftliche Istzustände, die die Kindesentwicklung, das Kindeswohl und insbesondere die gesundheitliche Versorgung von Kindern und Jugendlichen mit psychischer Störung beeinflussen und Anzeichen für Barrieren der Inklusion sind. Die Übersicht konzentriert sich auf Artikel der UN-Behindertenrechtskonvention, die für Aspekte von ethischer Haltung, Epidemiologie, klinischer Versorgungsstruktur, Diagnostik, Therapie, Lehre und Forschung im Rahmen der Kinder- und Jugendpsychiatrie von Bedeutung sind. Die Analyse verweist auf einen erheblichen Nachholbedarf in kinder- und jugendpsychiatrischer Versorgung, Lehre und Forschung.

Published: June 2015

Fragestellung: Die vorliegende Studie untersucht das schulische Wohlbefinden von SchülerInnen mit und ohne sonderpädagogischen Förderbedarf (SPF) in Integrationsklassen im Vergleich zu SchülerInnen aus Regelklassen, in welchen keine Kinder mit SPF unterrichtet werden. Zudem werden Zusammenhänge zwischen dem schulischen Wohlbefinden und emotionalen Problemen, Verhaltensauffälligkeiten, Hyperaktivität, Problemen mit Gleichaltrigen und prosozialem Verhalten analysiert. Methodik: Insgesamt 1.115 SchülerInnen (37 % SchülerInnen der 4. Schulstufe, 63 % SchülerInnen der 7. Schulstufe) nahmen an der Befragung teil, davon hatten 126 SchülerInnen einen SPF. Als Erhebungsinstrumente wurde die Skala «Wohlbefinden in der Schule» aus dem FEESS 3–4 ( Rauer & Schuck, 2004 ) sowie das SDQ ( Goodman, 1997 ) verwendet. Ergebnisse: Die Ergebnisse weisen hohe Reliabilitäten für die Skala «Wohlbefinden in der Schule» bei SchülerInnen mit und ohne SPF in beiden Schulstufen (4. vs. 7. Schulstufe) auf. Darüber hinaus wurde gezeigt, dass die Varianzaufklärung für das schulische Wohlbefinden sowohl Anteile auf der Ebene der individuellen SchülerInnen als auch Anteile auf der klassenspezifischen Ebene aufweist. Signifikante Prädiktoren des schulischen Wohlbefindens waren das Geschlecht, Verhaltensschwächen und -stärken sowie die Schulstufe. Der SPF-Status (kein SPF vs. SPF) sowie das Klassensetting (Regel- vs. Integrationsklasse) beeinflussten das schulische Wohlbefinden jedoch nicht signifikant.
Effects of Light-Hearted and Serious Entertainment on Enjoyment of	the First and Third Person
Authors: Hofer Matthias
Published: June 2015

Abstract. This was a study on the perceived enjoyment of different movie genres. In an online experiment, 176 students were randomly divided into two groups (n = 88) and asked to estimate how much they, their closest friends, and young people in general enjoyed either serious or light-hearted movies. These self–other differences in perceived enjoyment of serious or light-hearted movies were also assessed as a function of differing individual motivations underlying entertainment media consumption. The results showed a clear third-person effect for light-hearted movies and a first-person effect for serious movies. The third-person effect for light-hearted movies was moderated by level of hedonic motivation, as participants with high hedonic motivations did not perceive their own and others’ enjoyment of light-hearted films differently. However, eudaimonic motivations did not moderate first-person perceptions in the case of serious films.
Sexing the Avatar
Authors: Behm-Morawitz Elizabeth , Schipper Shannon
Published: June 2015

Abstract. The present study explored the influence of avatar appearance on cyber-harassment in a virtual world. Specifically, this research examined how avatar gender and sexualization were related to the experience of sex- and non-sex-related harassment. An international sample of Second Life users (N = 216) completed an online questionnaire about their avatar’s appearance and virtual world experiences. Objectification theory and the disinhibition effect were used as theoretical grounding for the study. Results revealed disparate virtual experiences for male and female avatars and indicated that avatar sexualization was related to experiences of cyber-harassment for female avatars. The implications of this research extend beyond virtual worlds like Second Life to other Web-based communication applications that utilize avatars.
The Mediating Role of Self-Talk Between Parenting Styles and Emotional Intelligence: An Asian Perspective With Singaporean Adolescents
Authors: Chong Wan Har , Chan Cynthia S. Y.
Published: June 2015

This study sought to extend knowledge about trait emotional intelligence (EI) by examining its relationship with paternal and maternal parenting styles and positive and negative self-talk among Singaporean adolescents. Students in Grades 6 through 8 (262, 49.3% girls, mean age = 13.94) completed instruments measuring trait EI, perceived authoritative, authoritarian, and permissive parenting styles, and positive and negative self-talk. Both paternal and maternal authoritative parenting styles together with positive self-talk emerged as significant predictors of different components of trait EI, suggesting that fathers’ and mothers’ perceived parenting styles have unique relations with different facets of emotion expression, management, and regulation. Positive self-talk mediated the relationship between perceived authoritative parenting styles and trait EI. Negative self-talk suppressed the relation between maternal authoritarian parenting and self-management of emotions. The findings provided further insights to inform how parenting practices and demands can foster self-talk that would have important implications for children’s socioemotional development.

Anatase is a pivotal material in devices for energy-harvesting applications and catalysis. Methods for the accurate characterization of this reducible oxide at the atomic scale are critical in the exploration of outstanding properties for technological developments. Here we combine atomic force microscopy (AFM) and scanning tunnelling microscopy (STM), supported by first-principles calculations, for the simultaneous imaging and unambiguous identification of atomic species at the (101) anatase surface. We demonstrate that dynamic AFM-STM operation allows atomic resolution imaging within the material’s band gap. Based on key distinguishing features extracted from calculations and experiments, we identify candidates for the most common surface defects. Our results pave the way for the understanding of surface processes, like adsorption of metal dopants and photoactive molecules, that are fundamental for the catalytic and photovoltaic applications of anatase, and demonstrate the potential of dynamic AFM-STM for the characterization of wide band gap materials.

Published: June 2015

Nicorandil is a vasodilatory drug used to relieve angina symptoms. Several healthcare products regulatory agencies have issued a warning associating the use of nicorandil and gastrointestinal (GI) ulceration. We aimed to evaluate the association between use of nicorandil and GI ulceration/perforation. A population-based cohort study involving 1 million randomly sampled participants in Taiwan’s National Health Insurance Research Database was carried out. We estimated the association between use of nicorandil and GI ulceration/perforation by a Cox proportional hazards regression model. A nicorandil-specific propensity score (PS) was also created for adjustment of 75 covariates and matching. 25.8% (183/710) of nicorandil-treated patients developed new GI ulcer events and 1.6% (20/1254) developed new GI perforation events in the three-year follow-up period, as compared to 9.3% (61,281/659,081) and 0.3% (2,488/770,537) in the general population comparator cohort. Patients treated with nicorandil were at significantly increased risk of GI ulcer (PS adjusted hazard ratio 1.43, 95% CI, 1.23 to 1.65, 6848 excess cases per 100,000 person years) or GI perforation (aHR 1.60, 95% CI 1.02–2.51, 315 excess cases per 100,000 person years) compared with the nicorandil unexposed population. Our finding may warn the clinicians to weigh the overall risk-benefit balance of nicorandil treatment in patients.
Protracted brain development in a rodent model of extreme longevity
Authors: Penz Orsolya K. , Fuzik Janos , Kurek Aleksandra B. , Romanov Roman , Larson John , Park Thomas J. , Harkany Tibor , Keimpema Erik
Published: June 2015

Extreme longevity requires the continuous and large-scale adaptation of organ systems to delay senescence. Naked mole rats are the longest-living rodents, whose nervous system likely undergoes life-long adaptive reorganization. Nevertheless, neither the cellular organization of their cerebral cortex nor indices of structural neuronal plasticity along extreme time-scales have been established. We find that adult neurogenesis and neuronal migration are not unusual in naked mole rat brains. Instead, we show the prolonged expression of structural plasticity markers, many recognized as being developmentally controlled and multi-year-long postnatal neuromorphogenesis and spatial synapse refinement in hippocampal and olfactory structures of the naked mole rat brain. Neurophysiological studies on identified hippocampal neurons demonstrated that morphological differentiation is disconnected from the control of excitability in all neuronal contingents regardless of their ability to self-renew. Overall, we conclude that naked mole rats show an extremely protracted period of brain maturation that may permit plasticity and resilience to neurodegenerative processes over their decades-long life span. This conclusion is consistent with the hypothesis that naked mole rats are neotenous, with retention of juvenile characteristics to permit survival in a hypoxic environment, with extreme longevity a consequence of greatly retarded development.
Permethyl Cobaltocenium (Cp*2Co+) as an Ultra-Stable Cation for Polymer Hydroxide-Exchange Membranes
Authors: Gu Shuang , Wang Junhua , Kaspar Robert B. , Fang Qianrong , Zhang Bingzi , Bryan Coughlin E. , Yan Yushan
Published: June 2015

Hydroxide (OH−)-exchange membranes (HEMs) are important polymer electrolytes enabling the use of affordable and earth-abundant electrocatalysts for electrochemical energy-conversion devices such as HEM fuel cells, HEM electrolyzers and HEM solar hydrogen generators. Many HEM cations exist, featuring desirable properties, but new cations are still needed to increase chemical stability at elevated temperatures. Here we introduce the permethyl cobaltocenium [(C5Me5)2Co(III)+ or Cp*2Co+] as an ultra-stable organic cation for polymer HEMs. Compared with the parent cobaltocenium [(C5H5)2Co(III)+ or Cp2Co+], Cp*2Co+ has substantially higher stability and basicity. With polysulfone as an example, we demonstrated the feasibility of covalently linking Cp*2Co+ cation to polymer backbone and prepared Cp*2Co+-functionalized membranes as well. The new cation may be useful in designing more durable HEM electrochemical devices.
Fast, multi-frequency and quantitative nanomechanical mapping of live cells using the atomic force microscope

Published: June 2015

A longstanding goal in cellular mechanobiology has been to link dynamic biomolecular processes underpinning disease or morphogenesis to spatio-temporal changes in nanoscale mechanical properties such as viscoelasticity, surface tension and adhesion. This requires the development of quantitative mechanical microscopy methods with high spatio-temporal resolution within a single cell. The Atomic Force Microscope (AFM) can map the heterogeneous mechanical properties of cells with high spatial resolution, however, the image acquisition time is 1–2 orders of magnitude longer than that required to study dynamic cellular processes. We present a technique that allows commercial AFM systems to map quantitatively the dynamically changing viscoelastic properties of live eukaryotic cells at widely separated frequencies over large areas (several 10’s of microns) with spatial resolution equal to amplitude-modulation (AM-AFM) and with image acquisition times (tens of seconds) approaching those of speckle fluorescence methods. This represents a ~20 fold improvement in nanomechanical imaging throughput compared to AM-AFM and is fully compatible with emerging high speed AFM systems. This method is used to study the spatio-temporal mechanical response of MDA-MB-231 breast carcinoma cells to the inhibition of Syk protein tyrosine kinase giving insight into the signaling pathways by which Syk negatively regulates motility of highly invasive cancer cells.
Comorbidity and survival among women with ovarian cancer: evidence from prospective studies
Authors: Jiao Yi-Sheng , Gong Ting-Ting , Wang Yong-Lai , Wu Qi-Jun
Published: June 2015

The relationship between comorbidity and ovarian cancer survival has been controversial so far. Therefore, we conducted a meta-analysis to summarize the existing evidence from prospective studies on this issue. Relevant studies were identified by searching the PubMed, EMBASE and ISI Web of Science databases through the end of January 2015. Two authors independently performed the eligibility evaluation and data abstraction. Random-effects models were used to estimate summary hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival. Eight prospective studies involving 12,681 ovarian cancer cases were included in the present study. The summarized HR for presenceversusabsence of comorbidity was 1.20 (95% CI = 1.11–1.30, n = 8), with moderate heterogeneity (I2 = 31.2%,P = 0.179). In addition, the summarized HR for the highest compared with the lowest category of the Charlson’s comorbidity index was 1.68 (95% CI = 1.50–1.87, n = 2), without heterogeneity (I2 = 0%,P = 0.476). Notably, a significant negative impact of comorbidity on ovarian cancer survival was observed in most subgroup analyses stratified by the study characteristics and whether there was adjustment for potential confounders. In conclusion, the findings of this meta-analysis suggest that underlying comorbidity is consistently associated with decreased survival in patients with ovarian cancer. Comorbidity should be taken into account when managing these patients.

Graph clustering by congruency approximation
Authors: Ren Weiya , Li Guohui , Tu Dan
Published: June 2015

The authors consider the general problem of graph clustering. Graph clustering manipulates the graph‐based data structure and the entries of the solution vectors are only allowed to take non‐negative discrete values. Finding the optimal solution is NP‐hard, so relaxations are usually considered. Spectral clustering retains the orthogonality rigorously but ignores the non‐negativity and discreteness of the solution. Sym non‐negative matrix factorisation can retain the non‐negativity rigorously but it is hard to reach the orthogonality. In this study, they proposed a novel method named congruent approximate graph clustering (CAC), which can retain the non‐negativity rigorously and can reach the orthogonality properly by congruency approximation. Furthermore, the solution obtained by CAC is sparse, which is approximate with the ideal discrete solution. Experimental results on several real image benchmark datasets indicate that CAC achieves encouraging results compared with state‐of‐the‐art methods.
Beyond the electric-dipole approximation: A formulation and implementation of molecular response theory for the description of absorption of electromagnetic field radiation
Authors: List Nanna Holmgaard , Kauczor Joanna , Saue Trond , Jensen Hans Jørgen Aagaard , Norman Patrick
Published: June 2015

We present a formulation of molecular response theory for the description of a quantum mechanical molecular system in the presence of a weak, monochromatic, linearly polarized electromagnetic field without introducing truncated multipolar expansions. The presentation focuses on a description of linear absorption by adopting the energy-loss approach in combination with the complex polarization propagator formulation of response theory. Going beyond the electric-dipole approximation is essential whenever studying electric-dipole-forbidden transitions, and in general, non-dipolar effects become increasingly important when addressing spectroscopies involving higher-energy photons. These two aspects are examined by our study of the near K-edge X-ray absorption fine structure of the alkaline earth metals (Mg, Ca, Sr, Ba, and Ra) as well as the trans-polyenes. In following the series of alkaline earth metals, the sizes of non-dipolar effects are probed with respect to increasing photon energies and a detailed assessment of results is made in terms of studying the pertinent transition electron densities and in particular their spatial extension in comparison with the photon wavelength. Along the series of trans-polyenes, the sizes of non-dipolar effects are probed for X-ray spectroscopies on organic molecules with respect to the spatial extension of the chromophore.
Determination of magnetic domain-wall types using Dzyaloshinskii–Moriya-interaction-induced domain patterns
Authors: Kim Dae-Yun , Kim Duck-Ho , Moon Joon , Choe Sug-Bong
Published: June 2015

The Néel-type domain-wall (DW) configuration caused by the Dzyaloshinskii–Moriya interaction has attracted significant attention because of its crucial role in current-induced DW motion. Here, we propose an experimental technique to determine the DW types (Néel or Bloch) by analyzing the asymmetry in domain expansion patterns. Such asymmetry is caused by the counterbalance between the Dzyaloshinskii–Moriya and Zeeman interactions, which results in the elongation of the domains either longitudinal (for Néel-type DWs) or transverse (for Bloch-type DWs) to the in-plane magnetic field. Therefore, the DW types can be determined simply by examining the elongation axis. The present technique is applicable even to a single image of the domain expansion pattern and provides a rapid determination of the DW configuration for exploring high-efficiency materials for current-induced DW motion in device applications.
