The Munik—Reteaming Method is a Way to Rehabilitate Psychosomatic and Work-Related Diseases and a Way to Create Healthy Psychosocial Workplaces
Authors: von Vultée Pia 
Published: November 2017

Background: Mental illness and stress are increasing at work. Sick leaves escalate. It is suggested to be due to organizational factors. There are a few methods to identify the organizational factors creating the negative psychosocial atmosphere at work. In Sweden, the work-related diseases have increased by 70% since 2010. Methods: Munik is a validated assessment instrument to identify psychosocial status among employees and find weak and strong organizational factors involved in the individual psychosocial well-being. We measure psychosocial well-being as mental energy, work-related exhaustion, and work satisfaction. Conclusions: In this study, we evaluate the treatment of employees at risk with low values on mental energy, high risk for developing work-related exhaustion, and reporting poor work satisfaction. Originality: We used Ben Furman’s positive solution-based coaching/therapy. This resulted in a more satisfied work group, and even though this group showed a large risk of developing work-related exhaustion in the start, none of the participants got on sick leave during the coaching/therapy period. After 3 months, 8 of 10 reported higher values on all 3 psychosocial levels measured.

Published: November 2017

Introduction Quality of life (QOL) is significantly impaired among individuals with post-traumatic stress disorder (PTSD); however, few treatment outcome studies examine QOL following treatment. Furthermore, the use of videoconferencing to deliver evidence-based treatments for PTSD is increasing dramatically. Although videoconferencing has demonstrated non-inferiority to in-person treatment modalities for improving PTSD symptom severity, no studies to date have directly compared QOL outcomes of an evidence-based intervention delivered via videoconferencing to one delivered in-person. Methods This study presents a secondary data analysis of two randomized controlled trials comparing cognitive processing therapy (CPT) delivered via videoconferencing or a traditional in-person modality. The Men’s study delivered group CPT to 125 male veterans with PTSD, whereas the Women’s study delivered individuals CPT to 126 female civilians and veterans. Multigroup latent growth curve models were used to model changes in QOL Inventory (QOLI) scores over time. Results There was no effect of treatment modality on changes in QOLI scores over time (modality effect on slope estimate = 0.004 (–0.60, 0.61) and on quadratic estimate = 0.001 (–0.18, 0.20); all ps > 0.33). Model fit was the same for both genders (Δ χ2 (2) = 2.28, p = 0.32) and for the gender × treatment modality interaction (Δ χ2 (2) = 2.87, p = 0.24). QOLI scores improved at post-treatment and three-month follow-up assessments, but declined at the six-month follow-up assessment. Discussion This secondary analysis extends the findings of the parent studies by establishing the efficacy of the videoconferencing platform in improving QOL. Clinical implications of findings are discussed.

Published: November 2017

Study Design: Meta-analysis. Objectives: To evaluate the long-term efficacy and safety of total disc replacement (TDR) compared with fusion in patients with functionally disabling chronic low back pain due to single-level lumbar degenerative disc disease (DDD) at 5 years. Methods: PubMed and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials reporting outcomes at 5 years for TDR compared with fusion in patients with single-level lumbar DDD. Outcomes included Oswestry Disability Index (ODI) success, back pain scores, reoperations, and patient satisfaction. All analyses were conducted using a random-effects model; analyses were reported as relative risk (RR) ratios and mean differences (MDs). Sensitivity analyses were conducted for different outcome definitions, high loss to follow-up, and high heterogeneity. Results: The meta-analysis included 4 studies. TDR patients had a significantly greater likelihood of ODI success (RR 1.0912; 95% CI 1.0004, 1.1903) and patient satisfaction (RR 1.13; 95% CI 1.03, 1.24) and a significantly lower risk of reoperation (RR 0.52; 95% CI 0.35, 0.77) than fusion patients. There was no association with improvement in back pain scores whether patients received TDR or fusion (MD −2.79; 95% CI −8.09, 2.51). Most results were robust to sensitivity analyses. Results for ODI success and patient satisfaction were sensitive to different outcome definitions but remained in favor of TDR. Conclusions: TDR is an effective alternative to fusion for lumbar DDD. It offers several clinical advantages over the longer term that can benefit the patient and reduce health care burden, without additional safety consequences.

Published: November 2017

Purpose Some research has suggested that discussion of prognosis can disrupt the patient-physician relationship. This study assessed whether physician discussion of prognosis is associated with detrimental changes in measures of the strength of the patient-physician relationship. Methods This was a longitudinal cohort study of 265 adult patients with advanced cancer who visited 38 oncologists within community- and hospital-based cancer clinics in Western New York and Northern California. Prognostic discussion was assessed by coding transcribed audio-recorded visits using the Prognostic and Treatment Choices (PTCC) scale and by patient survey at 3 months after the clinic visit. Changes in the strength of the patient-physician relationship were computed as differences in patient responses to The Human Connection and the Perceived Efficacy in Patient-Physician Interactions scales from baseline to 2 to 7 days and 3 months after the clinic visit. Results Prognostic discussion was not associated with a temporal decline in either measure. Indeed, a one-unit increase in PTCC during the audio-recorded visit was associated with improvement in The Human Connection scale at 2 to 7 days after the visit (parameter estimate, 0.10; 95% CI, −0.02 to 0.23) and 3 months after the visit (parameter estimate, 0.18; 95% CI, 0.02 to 0.35) relative to baseline. Standardized effect sizes (SES) associated with an increase of two standard deviations in the PTCC at each time point were consistent with small beneficial effects (SES, 0.14 [95% CI, −0.02 to 0.29] at 2 to 7 days; SES, 0.24 [95% CI, 0.02 to 0.45] at 3 months), and lower bounds of CIs indicated that substantial detrimental effects of prognostic discussion were unlikely. Conclusion Prognostic discussion is not intrinsically harmful to the patient-physician relationship and may even strengthen the therapeutic alliance between patients and oncologists.
Multiple limb salvage attempts for diabetic foot infections
Authors: Hong C. C. , Tan J. H. , Lim S. H. , Nather A. 
Published: November 2017

AimsLimb salvage for diabetic foot infections often require multiple procedures. Some patients will eventually end up with below knee amputation (BKA) when all limb salvage attempts fail. We seek to study the patients’ ability to return to normal life, functional status, prosthesis usage and perspectives on multiple limb salvage procedures that culminated in BKA to review if they would undertake a similar path if their situation was repeated.Patients and MethodsA total of 41 patients who underwent BKA between July 2011 and June 2013 were reviewed. They were divided into primary and creeping (prior multiple salvage procedures) amputations. The Barthel’s Index (BI) and the Reintegration to Normal Living Index (RNLI) were used. A questionnaire was used to identify whether the patient would undergo the same multiple attempts at limb salvage again if faced with the same problem.ResultsAll patients had a good mean BI of 14.2 (3 to 20) and RNLI of 73.2 (31 to 100). There was no difference in prosthesis usage, BI and RNLI between both groups. We found that 16 (94.1%) out of 17 patients with creeping amputation would undergo the same multiple salvage procedures if given a similar option. Conversely, only 15 (62.5%) patients with primary amputation would do the same again while the other nine (37.5%) patients choose to do everything possible to save their leg if faced with a similar situation (p = 0.001).ConclusionMost patients preferred to undergo multiple procedures to salvage the limb from diabetic foot infection even if it ultimately concluded with a BKA. All the patients had a moderately good functional outcome and ability to return to normal living after BKA. Cite this article: Bone Joint J 2017;99-B:1502–7.

Published: November 2017

AimsThe aims of the study were to review and analyse the reported series of debridement, antibiotics and implant retention (DAIR) in the management of infected total hip arthroplasties (THAs) to establish the overall success and the influencing factors.Patients and methodsUsing a standardised recognised study protocol, meta-analysis of observational studies in epidemiology guidelines, a comprehensive review and analysis of the literature was performed. The primary outcome measure was the success of treatment. The search strategy and inclusion criteria which involved an assessment of quality yielded 39 articles for analysis, which included 1296 patients.ResultsThe proportion of success following DAIR in the management of an infected THA appeared to improve after 2004 with a pooled mean proportion of success of 72.2%. For all reported series, from 1977 onwards, there was improved success with early debridement (< 7 days; 75.7%) and exchange of modular components (77.5%). There was a statistically non-significant improvement if debridement was performed within four weeks of the initial procedure (73.0%).ConclusionThe reported success following DAIR has improved since 2004. The only determinants of outcome which we found were the timing of debridement after the onset of symptoms of infection and the exchange of modular components.

A positive bacterial culture during re-implantation is associated with a poor outcome in two-stage exchange arthroplasty for deep infection
Authors: Akgün D. , Müller M. , Perka C. , Winkler T. 
Published: November 2017

Aims The aim of this study was to identify the incidence of positive cultures during the second stage of a two-stage revision arthroplasty and to analyse the association between positive cultures and an infection-free outcome. Patients and Methods This single-centre retrospective review of prospectively collected data included patients with a periprosthetic joint infection (PJI) of either the hip or the knee between 2013 and 2015, who were treated using a standardised diagnostic and therapeutic algorithm with two-stage exchange. Failure of treatment was assessed according to a definition determined by a Delphi-based consensus. Logistic regression analysis was performed to assess the predictors of positive culture and risk factors for failure. The mean follow-up was 33 months (24 to 48). Results A total of 163 two-stage revision arthroplasties involving 84 total hip arthroplasties (THAs) and 79 total knee arthroplasties (TKAs) were reviewed. In 27 patients (16.6%), ≥ 1 positive culture was identified at re-implantation and eight (29.6%) of these subsequently failed compared with 20 (14.7%) patients who were culture-negative. The same initially infecting organism was isolated at re-implantation in nine of 27 patients (33.3%). The organism causing re-infection in none of the patients was the same as that isolated at re-implantation. The risk of the failure of treatment was significantly higher in patients with a positive culture (odds ratio (OR) 1.7; 95% confidence interval (CI) 1.0 to 3.0; p = 0.049) and in patients with a higher Charlson Comorbidity Index (OR 1.5; 95% CI 1.6 to 1.8; p = 0.001). Conclusion Positive culture at re-implantation was independently associated with subsequent failure. Surgeons need to be aware of this association and should consider the medical optimisation of patients with severe comorbidities both before and during treatment.

Clicky hip alone is not a true risk factor for developmental dysplasia of the hip
Authors: Nie K. , Rymaruk S. , Paton R. W. 
Published: November 2017

Aims A clicky hip is a common referral for clinical and sonographic screening for developmental dysplasia of the hip (DDH). There is controversy regarding whether it represents a true risk factor for pathological DDH. Therefore a 20-year prospective, longitudinal, observational study was undertaken to assess the relationship between the presence of a neonatal clicky hip and pathological DDH. Patients and Methods A total of 362 infants from 1997 to 2016 were referred with clicky hips to our ‘one-stop’ paediatric hip screening clinic. Hips were assessed clinically for instability and by ultrasound imaging using a simplified Graf/Harcke classification. Dislocated or dislocatable hips were classified as Graf Type IV hips. Results The mean age at presentation was 13.8 weeks (12.8 to 14.7). In all 351 out of 362 children (97.0%) had Graf Type I hips (normal) that required no treatment. Nine children (2.5%) had Graf Type II hips but all resolved to Graf Type I hips on follow-up scans. One child (0.3%) had Graf Type III hip dysplasia and one child (0.3%) had an irreducible hip dislocation. The two pathological hips were associated with unilateral limited hip abduction. Mean referrals increased from 12.9 to 23.3 each year (p = 0.002) from the first decade of the study to the second, driven by increasing primary care referrals (5.5 versus 16.7 per year, p < 0.001). Conclusion Most clicky hips required no treatment other than reassurance to parents. Clicky hips with a normal hip examination should be considered a variant of normal childhood and not a risk factor for DDH. However, an abnormal hip examination including unilateral limited hip abduction should prompt urgent further investigations. Cite this article: Bone Joint J 2017;99-B:1533–6.
Assessing the readiness of precision medicine interoperabilty: An exploratory study of the National Institutes of Health genetic testing registry
Authors: Ronquillo Jay G , Weng Chunhua , Lester William T 
Published: November 2017

Background: Precision medicine involves three major innovations currently taking place in healthcare: electronic health records, genomics, and big data. A major challenge for healthcare providers, however, is understanding the readiness for practical application of initiatives like precision medicine.Objective: To better understand the current state and challenges of precision medicine interoperability using a national genetic testing registry as a starting point, placed in the context of established interoperability formats.Methods: We performed an exploratory analysis of the National Institutes of Health Genetic Testing Registry. Relevant standards included Health Level Seven International Version 3 Implementation Guide for Family History, the Human Genome Organization Gene Nomenclature Committee (HGNC) database, and Systematized Nomenclature of Medicine – Clinical Terms (SNOMED CT). We analyzed the distribution of genetic testing laboratories, genetic test characteristics, and standardized genome/clinical code mappings, stratified by laboratory setting.Results: There were a total of 25472 genetic tests from 240 laboratories testing for approximately 3632 distinct genes. Most tests focused on diagnosis, mutation confirmation, and/or risk assessment of germline mutations that could be passed to offspring. Genes were successfully mapped to all HGNC identifiers, but less than half of tests mapped to SNOMED CT codes, highlighting significant gaps when linking genetic tests to standardized clinical codes that explain the medical motivations behind test ordering. Conclusion: While precision medicine could potentially transform healthcare, successful practical and clinical application will first require the comprehensive and responsible adoption of interoperable standards, terminologies, and formats across all aspects of the precision medicine pipeline.
The critical role of assumptions in population projections : The case of Belgium
Authors: Vandresse Marie 
Published: November 2017

Population projections serve as a decision-making tool or as a tool to help contribute to discussions on the future of our societies. These projections are based on a series of choices made by the modeller about the projection methodology and the future trends in the population growth components (fertility, mortality and migration). To use these projections wisely, users should be aware of the impact of these choices on the results of a population projection. This article highlights the crucial role of the assumptions made on the future trends of the population growth components on the projection results, using population projections for Belgium published by national and international institutions.
English for sale: Using race to create value in the Korean ELT market
Authors: Jenks Christopher 
Published: November 2017

Abstract
Using Marxist notions of value, this study examines how the commodification of language instruction skews understandings of who is deemed a legitimate teacher of English in South Korea. The study argues that neoliberalism incentivizes the Korean ELT market to create value in race and racialized images. For example, the analysis explores how skin color, nationality, ethnicity, and facial morphology are used to sell an “authentic” and “Western” learning experience, thus creating exchange value in characteristics and features that are not traditionally associated with good language teaching, such as the ability to communicate information effectively. Analyzing interviews, job advertisements, and immigration documents from a critical discourse analytic perspective, the analysis uncovers how a market-driven ELT profession contributes to, and represents, a nexus of racially-motivated ideologies that circulates the discourse that English in South Korea is an indispensable form of upward mobility. The paper ends by contending that scholars and practitioners must do more to understand how constructs central to markets, such as value and commodity, shed light on pressing critical ELT issues.

Authors: Dautov Rafail Z. , Karchevskii Evgenii M. 
Published: November 2017

Abstract
The original problem for eigenwaves of weakly guiding
optical fibers formulated on the plane is reduced to a convenient for numerical solution
linear parametric eigenvalue problem posed in a disk. The study of the solvability of
this problem is based on the spectral theory of compact self-adjoint operators.
Properties of dispersion curves are investigated for the new formulation of the problem.
An efficient numerical method based on FEM approximations is developed. Error estimates
for approximate solutions are derived. The rate of convergence for the presented
algorithm is investigated numerically.
Estimator Based Inferential Control of an Ideal Quaternary Endothermic Reactive Distillation with Feed-Forward and Recurrent Neural Networks
Authors: K Mathew Anish , Pavan Kumar M V 
Published: November 2017

Abstract
A feed-forward neural network (FNN) and a layered recurrent neural network (LRNN) based two composition estimators, respectively, are designed for the purpose of tight product purity control for an ideal, quaternary, hypothetical, kinetically controlled, reactive distillation (RD) column. The output variables of the considered control structure i.e. the compositions, are estimated using the chosen tray temperatures as inputs to the estimators. The performances of the estimators in the control of the column for the servo, regulatory, feed impurity disturbances and catalyst deactivation are studied. The estimator based control is found to be effective for the on-spec product purity control. One-to-one relation between the number of tray temperature measurements and their sensitivity to the accuracy of estimation is observed. Overall, the performance of LRNN is found to be superior over the FNN for the throughput manipulations tested for the more number  of inputs to estimator.
Eight Common Fallacies of Elementary Semiotics
Authors: Pearson Charls 
Published: November 2017

Abstract
In this essay, eight fallacies of elementary semiotics are presented, analyzed from an empirical viewpoint, and corrected to the best of my present knowledge. These eight fallacies are called:

The Sign Fallacy
The Fallacy of Interpretation at a Distance
The Fallacy of Instantaneous Interpretation
The One-Way Interpretability Fallacy
The Inference Fallacy
The Fallacy of Things
The Fallacy of Isolation
The Realism Fallacy

By properly sensing and correcting these eight fallacies, we may see more deeply into semiotic structure, allowing us to develop theories more representative of that structure and thus reach a better understanding of the underlying semiotic reality. This advance in depth of understanding is comparable to the difference in depth of understanding of physical reality allowed by Aristotelian physics and that allowed by Newtonian physics. We can be optimistic, however, since we have the Einsteinian revolution in semiotics to look forward to.
Existential Universals
Authors: Tønnessen Morten 
Published: November 2017

Abstract
This paper is divided into five parts. The introduction presents some implications of the relational nature of human beings as well as other living beings, and establishes a connection between biosemiotics and existentialist thinking. The second part indicates key points of a “semiotics of being” as a genuine outlook within semiotics. In “Universals of biosemiosis”, the third part, a number of common features of everything and anyone alive are identified. The fourth part, “On Earth – the natural setting of the human condition”, sets the stage for a few ecologically and astronomically minded reflections in philosophical anthropology. In the fifth and concluding part, “On the alienation of the semiotic animal”, observations are made on some existential implications of the characteristically human form of being. Part of the motivation for the paper is to demonstrate, firstly, that existential semiosis plays a key role in human semiosis, and secondly, that other living beings too live through existential dramas.
