Case Report: ‘Z’ osteotomy - a novel technique of treatment in Blount’s disease
Authors: Karuppal Raju , Mohan Rahul , Marthya Anwar , TS Gopakumar , S Sandhya 
Published: November 2015

Blount’s disease is a progressive form of genu varum due to asymmetrical inhibition of the postero medial portion of the proximal tibial epiphysis. The surgical treatments involved in correction of Blount’s disease are often technically demanding, complicated procedures. These procedures can lead to prolonged recovery times and poor patient compliance. In such a context we are suggesting “fibulectomy with Z osteotomy” of the proximal tibia, a relatively simple and highly effective technique. This technique is based on correcting the mechanical axis of the lower limb thereby restoring growth from the medial physis of proximal tibia. We have used a new surgical technique, which includes fibulectomy followed by a Z-shaped osteotomy. We have used this simple technique in a 5 year-old boy with unilateral Blount’s disease. The femoro-tibial angle was corrected from 18.2° of varus to 4.2° of valgus. The angular correction obtained after operation was 22°. There were no postoperative complications. This technique has the advantages of correcting both angular and rotational deformities simultaneously. The purpose of this case study is to introduce a new surgical technique in the treatment of Blount’s disease.

Authors: Umeh Kanayo , Mackay Michael , Le-Brun Stephanie Davis 
Published: November 2015

Background:Uptake of information and communication technology (ICT) by individuals with diabetes can assist nursing care delivery, and improve patient outcomes. However, it is unclear how such uptake relates to ethnic differences in diabetes risk.Aim:To assess the moderating effects of ICT uptake on South Asian excess diabetes prevalence over a specific elapsed timeframe, accounting for selected environmental, socio-economic, and behavioural risk factors.Method:Archived data from a UK Office for National Statistics household survey 2006-2011 (120 621 partly non-orthogonal participant records) were analysed using hierarchical binary logistic regression analyses.Results:ICT uptake qualified ethnic differences in diabetes prevalence. Non-smoking diabetes cases living in terraced housing with a home computer were more likely to be South Asian than Caucasian. By contrast, such cases were more likely to be Caucasian if a computer was unavailable (OR: 0.61; CI: 0.43–0.86; P=0.005). Furthermore, diabetes cases from low-income, mobile-dependent homes were probably South Asian (OR: 0.05; CI: 0.00–0.50; P=0.012).Conclusions:Home computing was linked to better tobacco control among South Asians with diabetes living in terraced properties. Mobile phone dependence was pronounced in those that received income support. Implications for nursing care are considered.
Preceptors' views on their role in supporting newly qualified nurses
Authors: Tracey Julie M , McGowan Iain W 
Published: November 2015

Background: Retention, stress and difficult transition are issues associated with new graduates entering the workforce. International literature has suggested there is a problem and preceptorship models have been introduced to assist new registrants. It is recognised that new registrants require support from a preceptor, however, the literature appears to focus attention on the preceptee's views, rather than the preceptor's. Research Question: How do preceptors perceive their role in supporting newly qualified nurses/midwives? Aim: The aim of this article is to review the literature pertaining to preceptorship and explore the perceptions held by preceptors in relation to their role supporting newly qualified registrants. Method: A qualitative exploratory study was conducted using a purposive sample. Interviews were used to capture the data. Findings and Discussion: The data analysis identified that overall preceptors do feel prepared for their role, however, they highlighted the benefits of preceptor updates and regular support. Preceptors identified rewards and challenges associated with this role. Conclusions: The first 6 months of being a registrant has challenges for both the preceptee and the preceptor. The implementation of preceptorship models that include preparation and support for preceptors is essential to alleviate issues of transition, retention and stress. Preceptors identified areas for improvement such as regular update sessions, formal peer support, and protected time to discuss and complete the documentation.

<p class="p1">A városias környezetben lévő fák biztonságossága fontos kérdés. Kár keletkezhet többek között a fa tövestül kifordulásakor, aminek az esélye a gyökérzet stabilitásától függ. Ennek vizsgálatára jelenleg egyetlen, kellőképpen megbízható eredményeket adó mérési módszer ismeretes, a dőlésméréses húzóvizsgálat. Munkánk célja a húzóvizsgálat kiváltása más, új mérésekkel, illetve a kiválthatóság vizsgálata volt. Két módszert vizsgáltunk. Az egyikben a dőlésmérőt és a húzó acélkötelet helyettesítettük lézeres elmozdulás-méréssel illetve szélméréssel. A másik módszer a gyökérzet feltérképezése. A lézeres elmozdulás-mérés megfelelőnek bizonyult, helyettesítheti a nagyobb tehetetlenségű dőlésméréses eljárást. A szélben történő mérés szabadon álló fák esetében helyettesítheti a húzóvizsgálatot. A gyökértérképezés sikeres volt, azonban a számított eredmények a húzóvizsgálathoz képest konzisztensen alacsonyabbak lettek, ezért ez a módszer még finomításra szorul. </p>

<p>Wide usage of information technologies in banking, finance, health and other commercial sectors requires performing of audit of these sectors through information systems. Collecting and protecting electronic evidence is critically important for both judicial process and results of audit activities. Gathering electronic evidences from an information system is a subject for computer forensics and requires special expertise and equipment. Conversely, in Turkey, most of the institutions responsible for supervision of financial and other relevant sectors have not enough knowledge and experience about forensic audit. Due to the absence of technical knowledge and tools, there would be deficiencies in collecting electronic evidence in accurate manner. In order to prevent these deficiencies, some alternative solutions are offered in this study. These solutions are adapting the computer forensic techniques to audit processes, providing appropriate training to auditors, establishing a legal environment, sharing of information system audit resource and outsourcing of forensic audit activities.</p><p> </p><p><strong>Özet</strong></p><p>Bankacılık, finans, sağlık ve diğer ticari sektörlerde bilgi teknolojilerinin kullanımının artması, denetim faaliyetlerinin de bilgi sistemleri üzerinden gerçekleştirilmesi gereksinimini doğurmaktadır.

An investigation of the self-related concepts and foreign language motivation of young Deaf and hard-of-hearing learners in Hungary
Authors: Csizér Kata , Kontra Edit H. , Piniel Katalin 
Published: November 2015

In recent years increased attention has been given in applied linguistics to the learning processes of various groups of special needs (SN) students, especially to those whose achievement is impeded by dyslexia or other learning difficulties. However, students with sensory impairment, particularly those who are Deaf or severely hard of hearing (HOH), seem to have remained on the periphery of second language acquisition (SLA) research although they constitute a highly interesting group both from a linguistic as well as a cultural point of view. Since the best approach to understanding how this special minority handles foreign language learning is by first exploring their so-called individual differences, a nationwide research project was launched in Hungary to investigate students’ language learning beliefs, motivation, strategy use and motivated learning behavior. As part of that project, the present paper intends to detail how self-related concepts of hearing impaired students at eight different SN schools an be described. In order to gain an in-depth understanding, a mixed-method research design was employed. First, a barrier-free instrument was used to measure learner variables among 105 14-19-year-old Deaf and HOH learners. Then 31 individual interviews were conducted with selected students using maximum variety sampling. The quantitative data indicate that Deaf and HOH (D/HH) learners lack pronounced, well-developed and detailed future ideal L2 selves and corresponding visions to guide their learning. Another important finding is the paramount importance of language learning experience for our D/HH participants. Based on the analysis of the qualitative data, we can conclude that students’ language learning experiences are largely shaped by the choice of language used as the medium of education, the intensity and content of the English classes as well as how far students internalize extrinsic motives.

Endoxy – development and cultivation of textile-based gas membrane assemblies for endothelialized oxygenators
Authors: Neusser Christine , Finocchiaro Nicole , Hesselmann Felix , Cornelissen Christian , Gries Thomas , Jockenhoevel Stefan 
Published: November 2015

AbstractOne step to enable long-term use of extracorporeal membrane oxygenation devices or even the development of an artificial fully implantable lung is the endothelialization of oxygenator membranes in order to present a physiological and anti-thrombogenic surface to the blood flow. Since cell seeding decreases the gas transfer of oxygenation devices, a way to reincrease gas exchange performance by other means has to be found. In this study membrane assemblies suitable for endothelialization were developed, which profit from a secondary flow arrangement to increase gas transfer rates, the so-called Bellhouse effect. Therefore textiles that allow a homogeneous gas flow between the membranes and provide a structure that can be used as mold for hollow imprinting onto the membrane surfaces are combined with flat membranes to a sandwich structure. On top of that two approaches for hollow imprinting are generated and their results compared. The furrowed membrane assemblies are seeded with HUVECs and regularly inspected over 3 days cultivation. A surface characterization of the applied membranes is performed by contact angle measurement to identify reasons for inhomogeneous cell growth. In general first important results to develop a biohybrid lung assist device could be achieved in this study.

Abstract

Background: Low circulating homoarginine has been associated with adverse cardiovascular (CV) outcome and mortality in patients at risk and in the general population. The present study aimed to define plasma homoarginine reference intervals from a representative population sample to improve risk stratification between healthy individuals and individuals at risk.

Methods: We determined age- and sex-specific reference intervals for circulating plasma homoarginine in a subgroup of 786 healthy participants (no CV disease or risk factors) of the Gutenberg Health Study. Homoarginine concentrations were measured using a validated liquid chromatography-tandem mass spectrometry method.

Results: Median EDTA plasma homoarginine concentration was 1.88 [25th; 75th percentile, 1.47; 2.41] μmol/L, with lower concentrations in women (1.77 [1.38; 2.26] μmol/L) than in men (2.01 [1.61; 2.56] μmol/L; p<0.001). Sex-specific 2.5th and 97.5th percentiles of reference intervals were 0.84 and 3.89 μmol/L in women and 0.98 and 4.10 μmol/L in men, respectively. Homoarginine concentrations also depended on age and single nucleotide polymorphisms related to the L-arginine:glycine amidinotransferase gene.

Conclusions: We provide plasma homoarginine reference intervals in men and women of the general population. The determination of homoarginine levels might be favorable for individual risk stratification.

Abstract
New pyrazoles have been synthesized and evaluated as breast cancer cell growth inhibitors. Condensation of the substituted pyrazole-4-carbaldehyde 1 with acetophenone and chloroacetophenone afforded α, β-unsaturated ketones 2 and 3, respectively. Compounds 2 and 3 were subjected to different reactions using hydrazine hydrate, substituted hydrazine hydrate, hydroxylamine, o-phenylenediamine, malononitrile under different conditions affording 4-substituted pyrazole derivatives 4–28. Structure elucidation of these compounds was conducted using IR, 1H NMR, 13C NMR, mass spectral data and elemental analysis. Antitumor activity of target compounds was tested against MCF-7 cell line (human breast cancer). Compounds 4, 10 and 20 show significant antitumor activity against breast cancer. Docking was performed with protein 1UYK to study the binding mode of the designed compounds.

Abstract
Background: The aim of this study was to evaluate dietary quality of adolescents by using the Healthy Eating Index (HEI) and to assess their eating attitudes by the EAT-26 Eating Attitude Test.
Methods: Eight schools; four primary schools and four secondary schools were randomly selected from the school list of official website of Istanbul Education National Directorate. Five hundred and ninety-eight students who met the inclusion criteria included in the study, 24 h dietary recalls were collected to calculate their HEI scores and eating attitudes were evaluated by EAT-26 Eating Attitude Test. Their weight, height and waist circumference were measured.
Results: According to HEI scores, only two (0.3%) of adolescents had high quality diet, 379 (63.4%) had diet quality that needed improvement and 217 (36.3%) had poor diet. Regarding Eating Attitude Test scores, 513 (85.8%) had normal attitudes regarding eating behaviors.
Conclusion: Almost all of the participants need either development or major changes in their eating behaviors. Interventions aiming high quality diet among adolescents are strongly recommended.
Education of Children Gifted in Music: Experience of Teachers of Vilnius Choir Singing School “Liepaitės”
Authors: Šečkuvienė Henrika 
Published: November 2015

Objective of this survey is to detect experience of teachers working with children gifted in music. 8 teachers from Vilnius choir singing school “Liepaitės” have participated in this survey. Teachers representing different education stages and subjects were selected to identify overall picture of experience in education of children gifted in music. Semi-structured interview was employed to reveal in-depth experience from teacher‘s position, understand his position, feelings, how he works with children gifted in music. Thematic analysis method was employed for data analysis. Thee most significant themes were emphasized in interview data analysis: identification of children gifted in music, meeting demands for musical expression of children with different musical abilities and professional self-perception of the music teachers. Analysis of Lithuanian education instruments disclosed that children gifted in music have special needs and adequate education is necessary to meet them. Children gifted in music are educated in music schools. Music education in these schools is increasingly oriented towards meeting demands of the students for musical expression, purposeful extracurricular activities of students. Students with very different level of musical abilities are educated in music schools. One of the most critical challenges in this context is the issue of organizing education, identifying those who are mostly gifted in music and facilitating successful development of their musical abilities and on the other hand ensuring high quality music education for children with lower musical abilities. Results of the survey indicate that in identifying children gifted in music and establishing level of their musical abilities teachers build on their experience and assume the role of an expert, however they consider this a very complicated matter. Analysis of teachers’ experience indicate that collective musical activity (choir) is a very efficient tool to meet demands for musical expression of students with different musical abilities. Most students feel urged for achieving high learning results. Concert activities, continuous school traditions, consistency of education, continuity and succession, individual approach towards every student are elements which contribute most to the students’ motivation for learning. Results of the survey revealed that teachers feel satisfaction with their profession, employment position and it contributes to the possibility of being a member of powerful school community and team of professional teachers. Teachers analyse, perceive arising problems. They are concerned about the fact that some parents of the students regard musical education of the children as entertainment and not a systematic, responsible learning. Outdated programs, repertoire are indicated as a weakness. Teachers reflect on their activity and feel the demand for adaptation and changes in the context of dynamics of modern education.
