Current Concepts in Hip Preservation Surgery
Authors: Adler Kelly L. , Cook P. Christopher , Geisler Paul R. , Yen Yi-Meng , Giordano Brian D. 
Published: March 2015

Context: Successful treatment of nonarthritic hip pain in young athletic individuals remains a challenge. A growing fund of clinical knowledge has paralleled technical innovations that have enabled hip preservation surgeons to address a multitude of structural variations of the proximal femur and acetabulum and concomitant intra-articular joint pathology. Often, a combination of open and arthroscopic techniques are necessary to treat more complex pathomorphologies. Peri- and postoperative recovery after such procedures can pose a substantial challenge to the patient, and a dedicated, thoughtful approach may reduce setbacks, limit morbidity, and help optimize functional outcomes. Evidence Acquisition: PubMed and CINAHL databases were searched to identify relevant scientific and review articles through December 2014 using the search terms hip preservation, labrum, surgical dislocation, femoroacetabular impingement, postoperative rehabilitation, peri-acetabular osteotomy, and rotational osteotomy. Reference lists of included articles were reviewed to locate additional references of interest. Study Design: Clinical review. Level of Evidence: Level 4. Results: Hip preservation procedures and appropriate rehabilitation have allowed individuals to return to a physically active lifestyle. Conclusion: Effective postoperative rehabilitation must consider modifications and precautions specific to the particular surgical techniques used. Proper postoperative rehabilitation after hip preservation surgery may help optimize functional recovery and maximize clinical success and patient satisfaction.

Published: March 2015

Objective: The continual increase in production and disposal of nanomaterials raises concerns regarding the safety of nanoparticles on the environmental and human health. Recent studies suggest that cerium oxide (CeO2) nanoparticles may possess both harmful and beneficial effects on biological processes. The primary objective of this study is to evaluate how exposure to different concentrations (0.17–17.21 µg/mL) of aggregated CeO2 nanoparticles affects indices of whole animal stress and survivability in Caenorhabditis elegans. Methods: Caenorhabditis elegans were exposed to different concentrations of CeO2 nanoparticles and evaluated. Results: Our findings demonstrate that chronic exposure of CeO2 nanoparticle aggregates is associated with increased levels of reactive oxygen species and heat shock stress response (HSP-4) in Caenorhabditis elegans, but not mortality. Conversely, CeO2 aggregates promoted strain-dependent decreases in animal fertility, a decline in stress resistance as measured by thermotolerance, and shortened worm length. Conclusion: The data obtained from this study reveal the sublethal toxic effects of CeO2 nanoparticle aggregates in Caenorhabditis elegans and contribute to our understanding of how exposure to CeO2 may affect the environment.
Management of bronchiectasis in adults
Authors: Chalmers James D. , Aliberti Stefano , Blasi Francesco 
Published: March 2015

Formerly regarded as a rare disease, bronchiectasis is now increasingly recognised and a renewed interest in the condition is stimulating drug development and clinical research. Bronchiectasis represents the final common pathway of a number of infectious, genetic, autoimmune, developmental and allergic disorders and is highly heterogeneous in its aetiology, impact and prognosis.The goals of therapy should be: to improve airway mucus clearance through physiotherapy with or without adjunctive therapies; to suppress, eradicate and prevent airway bacterial colonisation; to reduce airway inflammation; and to improve physical functioning and quality of life.Fortunately, an increasing body of evidence supports interventions in bronchiectasis. The field has benefited greatly from the introduction of evidence-based guidelines in some European countries and randomised controlled trials have now demonstrated the benefit of long-term macrolide therapy, with accumulating evidence for inhaled therapies, physiotherapy and pulmonary rehabilitation.This review provides a critical update on the management of bronchiectasis focussing on emerging evidence and recent randomised controlled trials.
Matching strategies of teachers and schools in general equilibrium
Authors: Ahn Tom 
Published: March 2015

Abstract
I use a structural matching model, North Carolina public school data, and a survey of teachers’ career plans to analyze schools’ and teachers’ behaviors in the teacher transfer market. Results show that mid-career teachers with better pre-service qualifications are the most eager to search, different types of teachers and schools have different search strategies, and the market is turbulent, characterized by search friction and large movements of teachers to better, worse, or comparable schools. The market is not as stable and orderly as it may first appear. Simulations show that simple policies to direct teacher transfers are at best inefficient.

Authors: Bölte Sven , Ciaramidaro Angela , Schlitt Sabine , Hainz Daniela , Kliemann Dorit , Beyer Anke , Poustka Fritz , Freitag Christine , Walter Henrik 
Published: March 2015

BackgroundAutism spectrum disorder (ASD) is linked to social brain activity and facial affect recognition (FAR).AimsTo examine social brain plasticity in ASD.MethodUsing FAR tests and functional magnetic resonance imaging tasks for FAR, we compared 32 individuals with ASD and 25 controls. Subsequently, the participants with ASD were assigned to FAR computer-aided cognitive training or a control group.ResultsThe ASD group performed more poorly than controls on explicit behavioural FAR tests. In the scanner, during implicit FAR, the amygdala, fusiform gyrus and other regions of the social brain were less activated bilaterally. The training group improved on behavioural FAR tests, and cerebral response to implicit affect processing tasks increased bilaterally post-training in the social brain.ConclusionsIndividuals with ASD show FAR impairments associated with hypoactivation of the social brain. Computer-based training improves explicit FAR and neuronal responses during implicit FAR, indicating neuroplasticity in the social brain in ASD.

Published: March 2015

BackgroundResearch on mental well-being is relatively new and studies of its
determinants are rare.AimsTo investigate whether the socioeconomic correlates of mental well-being
mirror those for mental illness.MethodUsing logistic regression analyses, the independent odds ratios of high
and low mental well-being, compared with middle-range mental well-being,
were estimated for a number of sociodemographic variables known to be
associated with mental illness from 13 983 participants in the 2010 and
2011 Health Surveys for England.ResultsIndependent odds ratios for low mental well-being were as expected from
studies of mental illness with increased odds for the unemployed (OR =
1.46, 95% CI 1.01–2.10) and those aged 35–54 years (OR = 1.58, 95% CI
1.35–1.84) and reduced odds for the married (OR = 0.78, 95% CI
0.62–0.97). A linear trend was observed with education and equivalised
income. Odds ratios for high mental well-being differed from those for
low mental well-being with regard to age (55+ years: OR = 1.48, 95% CI
1.23–1.79); employment status where there was an association only with
retirement (OR = 1.35, 95% CI 1.09–1.69); education where there was no
association; and equivalised income for which the association was
non-linear.ConclusionsOdds ratios for low mental well-being mirrored those for mental illness,
but not those for high mental well-being, suggesting that the
socioeconomic factors associated with positive mental health are
different from those associated with mental illness.
DRD3 gene and striatum in autism spectrum disorder
Authors: Staal Wouter G. , Langen Marieke , van Dijk Sarai , Mensen Vincent T. , Durston Sarah 
Published: March 2015

SummaryA single-nucleotide polymorphism (SNP) of the DRD3 gene (rs167771) was recently associated with autism spectrum disorders (ASD). Different polymorphisms of rs167771 corresponded to varying degrees of stereotyped behaviour. As DRD3 receptors are relatively overexpressed in the striatum, we investigated whether striatal volume was related to these polymorphisms in autism. We assessed volumes of caudate nucleus and putamen in 86 participants with ASD (mean age 15.3 years). MANCOVA showed an association between alleles of the rs167771 SNP and the volume of striatal structures. Furthermore, greater caudate nucleus volume correlated with stereotyped behaviour. These findings support a relationship between DRD3 gene SNPs, striatum and stereotyped behaviour in ASD.

BackgroundA substantial number of people with bipolar disorder show a suboptimal response to treatment.AimsTo study the effectiveness of a collaborative care programme on symptoms and medication adherence in patients with bipolar disorder, compared with care as usual.MethodA two-armed, cluster randomised clinical trial was carried out in 16 out-patient mental health clinics in The Netherlands, in which 138 patients were randomised. Patient outcomes included duration and severity of symptoms and medication adherence, and were measured at baseline, 6 months and 12 months. Collaborative care comprised contracting, psychoeducation, problem-solving treatment, systematic relapse prevention and monitoring of outcomes. Mental health nurses functioned as care managers in this programme. The trial was registered with The Netherlands Trial Registry (NTR2600).ResultsCollaborative care had a significant and clinically relevant effect on number of months with depressive symptoms, both at 6 months (z =–2.6, P = 0.01, d = 0.5) and at 12 months (z =–3.1, P = 0.002, d = 0.7), as well as on severity of depressive symptoms at 12 months (z =–2.9, P = 0.004, d = 0.4). There was no effect on symptoms of mania or on treatment adherence.ConclusionsWhen compared with treatment as usual, collaborative care substantially reduced the time participants with bipolar disorder experienced depressive symptoms. Also, depressive symptom severity decreased significantly. As persistent depressive symptoms are difficult to treat and contribute to both disability and impaired quality of life in bipolar disorder, collaborative care may be an important form of treatment for people with this disorder.

Abstract
The recovery of lithium resources from salt lake brine has become more and more important. Tri-n-butyl phosphate (TBP) is the most common extractant and has good ability to selectively extract lithium, thus, basic research on it should be carried out. In this study, the kinetics of lithium extraction by TBP in salt lake brine was investigated at 298.15 K via a single rising drop technique. Parameters affecting the mass transfer mechanism, including the interfacial area, lithium concentration, iron concentration, TBP concentration, and temperature were studied. According to this research, we found that the process of extraction is controlled by the diffusion and the chemical reaction occurs at the interfacial area. The mechanism of the lithium extraction with TBP is revealed.

Authors: Lapum Jennifer L , Yau Terrence , Church Kathryn 
Published: March 2015

Background:The knowledge translation capacity of cardiovascular research has had little impact on systems of care following discharge specific to the home period of recovery.Aims:The focus of this article is to provide an arts-informed dissemination in the form of a poem, to provide readers with the opportunity to engage with patients’ experiences on an emotive and visceral level.Methods:In order to explore 16 patients’ experiences of recovery from heart surgery, a narrative methodology was employed using journal writing and interviews. Research findings were reconstructed by the lead author into poetry, using words taken directly from interviews, to create a composite story of participants’ experiential accounts of recovery in the home.Results:Findings provide an intimate account of recovery as an emotional and physical experience that occurs in the isolation of one's home, interwoven with contemplations of mortality and unanswered questions.Conclusion:There is a need to implement and test interventions aimed at the care of cardiovascular patients during the home period of recovery.
Optimizing the use of the “state-of-the-art” performance criteria
Authors: Haeckel Rainer , Wosniok Werner , Streichert Thomas 
Published: March 2015

AbstractThe organizers of the first EFLM Strategic Conference “Defining analytical performance goals” identified three models for defining analytical performance goals in laboratory medicine. Whereas the highest level of model 1 (outcome studies) is difficult to implement, the other levels are more or less based on subjective opinions of experts, with models 2 (based on biological variation) and 3 (defined by the state-of-the-art) being more objective. A working group of the German Society of Clinical Chemistry and Laboratory Medicine (DGKL) proposes a combination of models 2 and 3 to overcome some disadvantages inherent to both models. In the new model, the permissible imprecision is not defined as a constant proportion of biological variation but by a non-linear relationship between permissible analytical and biological variation. Furthermore, the permissible imprecision is referred to the target quantity value. The biological variation is derived from the reference interval, if appropriate, after logarithmic transformation of the reference limits.
Pharmacogenetics of drug metabolizing enzymes in the United Kingdom population: review of current knowledge and comparison with selected European populations
Authors: Daly Ann K. 
Published: March 2015

Abstract
Data on frequency of pharmacogenetic polymorphisms in the UK population are limited. However, availability of whole genome sequencing data on 94 UK controls of European ethnicity from the 1000 genomes project together with similar data on other populations provides a valuable new source of data in this area and allows direct comparison of allele frequencies with those for other European populations. The ethnic diversity of the UK population also needs to be considered, and 1000 genomes includes data on South Asians, the most common ethnic group in the UK after White Europeans. Allele frequencies for polymorphisms in genes relevant to phase I and phase II drug metabolism for UK, Finnish, Spanish and South Asian populations were obtained from the literature and 1000 genomes. Generally there was good agreement between the literature and 1000 genomes reports. CYP2D6*4, the most common CYP2D6 poor metabolizer allele among Europeans, appears more common in the UK than in Spain and Finland, whereas, as suggested previously, CYP2C19*2 and CYP2C9*2 appear more common in Finland and Spain, respectively, than in the UK. South Asians show low frequencies of CYP2C9*2 and CYP2C19*17 but higher frequencies of CYP2C19*2 compared with UK residents of European ethnicity. Though personalizing drug treatment on the basis of individual genotype rather than ethnicity may be more appropriate, differences in allele frequencies across continents should be considered when designing clinical trials of new drugs.
Comparison of Different Models for Ground-Level Atmospheric Attenuation Prediction with New Models According to Local Weather Data for FSO Applications
Authors: Arockia Bazil Raj A. , Arputha Vijaya Selvi J. 
Published: March 2015

AbstractA dedicated Free Space Optical Link (FSOL) for the range of 0.5 km at an altitude of 15.25 m is established and explained. The power levels of the received signal with meteorological parameters are continuously measured using the opto-electronic assembly and developed weather station respectively and stored in a computer. The existing models selected for comparative analysis are briefed. Measured meteorological parameters and optical attenuation of size [2000×4] are used for linear regression analysis as well as to design the mathematical models more suitable at the test field. In addition, the prediction accuracy of the proposed and selected models during different seasons in one-year period are investigated and validated in terms of RMSE. The average Root Mean Square Error (RMSE) of 0.041 dB/km for the optical attenuation is achieved in the longer range dynamic of meteorological parameters during different local seasons.

Authors: Mahanty Bholanath , Mohapatra Prasanta Kumar , Raut Dhaval Ramakant , Das Dillip Kumar , Behere Praveen Gajanan , Afzal Mohammad 
Published: March 2015

Abstract
Polymer inclusion membranes (PIM) containing N,N,N′,N′-tetra(2-ethylhexyl) diglycolamide (T2EHDGA) were
evaluated for the separation of actinide ions such as Am3+, Pu4+, UO2
2+ and Th4+ from acidic
feeds. The PIMs were prepared using cellulose triacetate (CTA) as the polymer matrix, 2-nitrophenyloctyl ether (NPOE) as the
plasticizer and T2EHDGA as the carrier extractant and the optimized membrane composition was found to be 68.4% T2EHDGA,
17.9% NPOE and 13.7% CTA which resulted in 74% Am3+ uptake at 1 M HNO3 in
2 h. The uptake studies were carried out using feed solutions containing varying concentrations of nitric acid
(0.5–3.0 M) and showed the trend: Pu4+ > Am3+ > Th4+ >
UO2
2+. Quantitative stripping (> 99%) of the sorbed Am3+ was possible using a solution containing
0.01 M EDTA at pH 3.0. Reusability studies indicated deterioration of the PIM on continuous use.
Integración conceptual (blending) en el proceso de gramaticalización de construcciones nominales cuantificativas en español
Authors: Huelva Enrique 
Published: March 2015

Abstract
The primary purpose of this article is to examine the cognitive underpinnings of grammaticalization processes that generate quantifier noun constructions in Spanish. This analysis aims to demonstrate the need to develop a cognitive model of grammaticalization based on the Theory of Blending. Grammaticalization is thus considered a specific case of blending. The main argument sustaining this position lies in the emergent properties of the constructions that result from grammaticalization processes. Finally, a framework for such a model is outlined and its comparative advantages vis-à-vis other cognitive models of grammaticalization proffered in the literature are explained.
Homeless in Post-Modern Linguistics? (Re/Dis)placing Hispanic Dialectology
Authors: Lipski John M. 
Published: March 2015

Abstract
Within the context of contemporary Hispanic linguistics, dialectology is often felt to be an anachronism, a notion grounded in the stereotype of the dialectologist as linguistic butterfly-collector. In fact this view is as unrealistic in the 21st century as the concept of a physician administering leeches and “philtres,” and stems from a failure to acknowledge that dialectology has evolved together with the rest of linguistics. Dialectology as currently practiced is best defined as the response to the question of how and why languages vary regionally and socially. As such, dialectology intersects with, but is not superseded by, sociolinguistics; contemporary dialectology includes theoretical advances in syntax, phonology, phonetics, historical linguistics, and variational linguistics.
Affirming Differences, Valuing Variation and Dismissing Dialects in Modern Linguistics
Authors: Otheguy Ricardo 
Published: March 2015

Abstract
Dialectology and sociolinguistics have given rise to the notions of dialect difference and sociolinguistic variation. An evaluation of these concepts in terms of usefulness to scholars, social relevance to laymen, and solid intellectual coherence and soundness yields high marks on the first two criteria, while pointing to problems with regard to coherence. The scientific and social contributions made possible by the concept of dialectal difference are clear, but serious questions must be raised as to the coherence of the notion of dialect. The concept of variation, while also facilitating important contributions, raises questions of its own on the criterion of coherence. Dialects can be safely dismissed from our conceptual repertoire, while dialectal difference and sociolinguistic variation should remain, demanding, however, that considerable effort be expended in finding a better fit with more traditional areas of research in linguistics. These areas are not exempt from the task, as their coherence too requires greater engagement with variation.
