AimsThe optimal method of tibial component fixation remains uncertain in total knee arthroplasty (TKA). Hydroxyapatite coatings have been applied to improve bone ingrowth in uncemented designs, but may only coat the directly accessible surface. As peri-apatite (PA) is solution deposited, this may increase the coverage of the implant surface and thereby fixation. We assessed the tibial component fixation of uncemented PA-coated TKAs versus cemented TKAs.Patients and MethodsPatients were randomised to PA-coated or cemented TKAs. In 60 patients (30 in each group), radiostereometric analysis of tibial component migration was evaluated as the primary outcome at baseline, three months post-operatively and at one, two and five years. A linear mixed-effects model was used to analyse the repeated measurements.ResultsAfter five years of follow-up, one (cemented) component was revised due to ligament instability. Overall, uncemented PA-coated tibial components migrated significantly more (p = 0.003), with the mean maximum total point motion (MTPM) at five years being 0.62 mm (95% confidence intervals (CI) 0.49 to 0.76) for cemented tibial components and 0.97 mm (95% CI 0.81 to 1.15) for PA-coated tibial components in TKA. However, between three months and five years the cemented TKAs migrated significantly more (p = 0.02), displaying a MTPM of 0.27 mm (95% CI, 0.19 to 0.36) versus 0.13 mm (95% CI, 0.01 to 0.25) for PA-coated tibial components. One implant in each group was considered at risk for aseptic loosening due to continuous migration after five years of follow-up, albeit with different migration patterns for each group (i.e. higher initial migration but diminishing over time for the PA-coated component versus gradually increasing migration for the cemented component).ConclusionThe tibial components of PA-coated TKAs showed more overall migration compared with the tibial components of cemented TKAs. However, post hoc analysis showed that this difference was caused by higher migration of PA-coated components in the first three months, after which a stable migration pattern was observed. Clinically, there was no significant difference in outcome between the groups. Cite this article: Bone Joint J 2017;99-B:1467–76.

AimsWe report the incidence of radiolucent lines (RLLs) using two flanged acetabular components at total hip arthroplasty (THA) and the effect of the Rim Cutter.Patients and MethodsWe performed a retrospective review of 300 hips in 292 patients who underwent primary cemented THA. A contemporary flanged acetabular component was used with (group 1) and without (group 2) the use of the Rim Cutter and the Rimfit acetabular component was used with the Rim Cutter (group 3). RLLs and clinical outcomes were evaluated immediately post-operatively and at five years post-operatively.ResultsThere was no significant difference in the incidence of RLLs on the immediate post-operative radiographs (p = 0.241) or at five years post-operatively (p = 0.463). RLLs were seen on the immediate post-operative radiograph in 2% of hips in group 1, in 5% in group 2 and in 7% in group 3. Five years post-operatively, there were RLLs in 42% of hips in group 1, 41% in group 2 and in 49% in group 3. In the vast majority of hips, in each group, the RLL was present in DeLee and Charnley zone 1 only (86%, 83%, 67% respectively). Oxford and Harris Hip scores improved significantly in all groups. There was no significant difference in these scores or in the change in scores between the groups, with follow-up.ConclusionDespite the Rim Cutter showing promising results in early laboratory and clinical studies, this analysis of the radiological and clinical outcome five years post-operatively does not show any advantage over and above modern cementing techniques in combination with a well performing cemented acetabular component. For this reason, we no longer use the Rim Cutter in routine primary THA. Cite this article: Bone Joint J 2017;99-B:1450–7.

Aims The Corail stem has good long-term results. After four years of using this stem, we have detected a small group of patients who have presented with symptomatic metaphyseal debonding. The aim of this study was to quantify the incidence of this complication, to delineate the characteristics of patients presenting with this complication and to compare these patients with asymptomatic controls to determine any important predisposing factors. Patients and Methods Of 855 Corail collarless cementless stems implanted for osteoarthritis, 18 presented with symptomatic metaphyseal debonding. A control group of 74 randomly selected patients was assembled. Clinical and radiological parameters were measured and a logistic regression model was created to evaluate factors associated with metaphyseal debonding. Results The prevalence of this complication was 2.1% in our series. In the multivariable model, the presence of a Dorr B-type proximal femur was associated with metaphyseal debonding (odds ratio (OR) 10.73, 95% confidence interval (CI) 2.31 to 49.97, p = 0.002), as was a body mass index > 25 kg/m2 (OR 6.85, 95% CI 1.06 to 44.28, p = 0.04). Smaller stems and the use of a polyethylene acetabular liner appeared to be protective when compared with metal and ceramic setting hard-on-hard bearings. Conclusion We have described an uncommon but important mode of failure of the Corail stem. Surgeons should be aware of this phenomenon; overweight patients with Dorr B-type femurs and in whom hard bearings are used appear to be particularly at risk.

Aims To determine the incidence and timing of post-operative fevers following shoulder arthroplasty and the resulting investigations performed. Patients and Methods A retrospective review was conducted of all patients undergoing shoulder arthroplasty over a nine-year period. The charts of all patients with a post-operative fever (≥ 38.6°C) were reviewed and the results of all investigations were analysed. Results A total of 2167 cases (in 1911 patients) were included of whom 92 (4.2%) had a documented fever. Obese cases had a significantly greater risk for fever (relative risk 1.53; 95% confidence interval 1.02 to 2.32; p = 0.041). Investigations were performed in 43/92 cases (46.7%), with a diagnosis being made in six cases (6.6% of the total, two of whom had their diagnosis made post-discharge). Conclusion Around one in 25 cases develop a fever following shoulder arthroplasty; most have no infective aetiology. These patients may be being over-investigated; investigations should be performed in patients with persistent fever or on those with an identifiable source of infection on clinical examination.

Population-based contracting (population health)
Authors: Jacofsky D. J. 
Published: November 2017

Modern healthcare contracting is shifting the responsibility for improving quality, enhancing community health and controlling the total cost of care for patient populations from payers to providers. Population-based contracting involves capitated risk taken across an entire population, such that any included services within the contract are paid for by the risk-bearing entity throughout the term of the agreement. Under such contracts, a risk-bearing entity, which may be a provider group, a hospital or another payer, administers the contract and assumes risk for contractually defined services. These contracts can be structured in various ways, from professional fee capitation to full global per member per month diagnosis-based risk. The entity contracting with the payer must have downstream network contracts to provide the care and facilities that it has agreed to provide. Population health is a very powerful model to reduce waste and costs. It requires a deep understanding of the nuances of such contracting and the appropriate infrastructure to manage both networks and risk. Cite this article: Bone Joint J 2017;99-B:1431–4.
Posterior malleolus fractures
Authors: Solan M. C. , Sakellariou A. 
Published: November 2017

The posterior malleolus component of a fracture of the ankle is important, yet often overlooked. Pre-operative CT scans to identify and classify the pattern of the fracture are not used enough. Posterior malleolus fractures are not difficult to fix. After reduction and fixation of the posterior malleolus, the articular surface of the tibia is restored; the fibula is out to length; the syndesmosis is more stable and the patient can rehabilitate faster. There is therefore considerable merit in fixing most posterior malleolus fractures. An early post-operative CT scan to ensure that accurate reduction has been achieved should also be considered.

Vital Gluten for Particleboard Production: Effect of Wood-Particle Moisture on Board Properties
Authors: Trischler Johann , Dorn Michael , Sandberg Dick 
Published: November 2017

Abstract
Growing environmental awareness is leading to an increased interest in the use of biobased adhesives and proteins such as vital gluten. The purpose of this study was to investigate the influence of the wood-particle moisture content, water application, and press time on the internal bond strength, thickness expansion, and thickness swelling of particleboards glued with vital gluten. Green and dried wood particles with similar moisture content were achieved through drying or water addition and were blended with vital gluten powder and pressed for 1 to 3 minutes. The results show that not only the pressing time and moisture content, but also the way of achieving the moisture content, has a strong impact on the performance of the boards. At comparable moisture content, never-dried (green) particles with high moisture content in combination with a dry adhesive application produced boards that performed better than boards made of dry particles with water addition to simulate liquid adhesive application.

Published: November 2017

Abstract
The purpose of this study was to evaluate the impact of glue line thickness on joint strength properties while using two types of PVAc adhesive (i.e., one-component Rhenocell 3W, 4B Plus, resistivity class D3, and two-component Protovil VP244/2C, resistivity class D4) belonging to the group of thermoplastic adhesives intended for nonconstruction joints. Joint strength testing was carried out using the transverse tensile test for estimation of the joint strength method. It was proven that if specimens were conditioned for 7 days at 20°C ± 2°C and a relative air humidity of 65 ± 5 percent, when testing one-component Rhenocell 3W, 4B Plus (D3) adhesive, increasing thickness of the glue line results in falling strength of the bonded joint. When testing the two-component Protovil VP244/2C (D4) adhesive, increasing thickness of the glue line always results in increasing joint strength, even under conditions when water is directly affecting the joint or under increased temperatures.
Methods to Describe Referral Patterns in a Canadian Primary Care Electronic Medical Record Database: Modelling Multilevel Count Data
Authors: Ryan Bridget L , Shadd Joshua , Maddocks Heather , Stewart Moira , Thind Amardeep , Terry Amanda L 
Published: November 2017

Background: A referral from a family physician (FP) to a specialist is an inflection point in the patient journey, with potential implications for clinical outcomes and health policy. Primary care electronic medical record (EMR) databases offer opportunities to examine referral patterns. Until recently, software techniques were not available to model these kinds of multi-level count data. Objective: To establish methodology for determining referral rates from FPs to medical specialists using the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) EMR database. Method: Retrospective cohort study, mixed effects and multi-level negative binomial regression modelling with 87,258 eligible patients between 2007 and 2012. Mean referrals compared by patient sex, age, chronic conditions, FP visits, and urban/rural practice location. Proportion of variance in referral rates attributable to the patient and practice levels. Results: On average, males had 0.26, and females 0.31 referrals in a 12-month period. Referrals were significantly higher for females, increased with age, FP visits, and number of chronic conditions (p<.0001). Overall, 14% of the variance in referrals could be attributed to the practice level, and 86% to patient level characteristics. Conclusions: Both patient and practice characteristics influenced referral patterns. The methodologic insights gained from this study have relevance to future studies on many research questions that utilize count data, both within primary care and broader health services research. The utility of the CPCSSN database will continue to increase in tandem with data quality improvements, providing a valuable resource to study Canadian referral patterns over time.
Aristotle and Augustine
Authors: Daylight Russell 
Published: November 2017

Abstract
The unification of the theory of semiotics has been an ambition of the IASS-AIS since the First World Congress in 1974. In his Preface to the Proceedings, Umberto Eco set the participants with certain fundamental tasks, including “providing the discipline with a unified methodology and a unified objective.” At the Second Congress, however, the multitude of topics and approaches led to the prevailing question of the Closing Session: “Can Semiotics Be Unified?” By the Fifth Congress the organizers would claim that theoretical differences “served to strengthen rather than to divide.” This paper traces the origin of this disunity to the writings of Aristotle and their interpretation by late classical and medieval theologians. Received wisdom tells us that linguistic semiology forms a part of general semiotics – the part dealing with either linguistic or conventional signs. This paper overturns that view, demonstrating that (linguistic) relations of equivalence and (semiotic) relations of implication operate in perpendicular planes of semiosis, intersecting at the point of the thing itself. These two planes of semiosis exist as unconnected theories in Aristotle, but become conflated in Augustine. This paper resolves the relationship between semiotics and semiology and in doing so, provides a unified methodology and objective.
Numerals in Lokono-Wayuunaiki: Reconstruction and implications for internal classification
Authors: de Carvalho Fernando O. 
Published: November 2017

AbstractThe goal of this paper is to contribute to the understanding of the diachronic development of the Lokono-Wayuunaiki subgroup of the Arawak language family by focusing on a structured set of lexemes of recurrent interest for historical linguists. In this paper, I reconstruct the cardinal numerals from ‘one’ to ‘four’ in Proto-Lokono-Wayuunaiki (PLW). For each reconstructed etymon, I will discuss how regular sound change and attested morphological patterns support the reconstructed forms and the implied diachronic developments in the two daughter languages, Lokono and Wayuunaiki. On the basis of these reconstructions, I argue that the form for ‘three’ and the construction involved in the derivation of the form for ‘four’ constitute innovations shared only by Lokono and Wayuunaiki among Arawak languages, thus supporting the recognition of Lokono-Wayuunaiki as a legitimate subgroup of the Arawak family.
Linguistic homoplasy and phylogeny reconstruction. The cases of Lezgian and Tsezic languages (North Caucasus)
Authors: Kassian Alexei S. 
Published: November 2017

AbstractThis paper deals with the problem of linguistic homoplasy (parallel or backward development), how it can be detected, what kinds of linguistic homoplasy can be distinguished and which varieties of the phenomenon are the most deleterious for the reconstruction of language phylogeny. It is proposed that language phylogeny reconstruction should consist of two main stages. Firstly, a strict consensus tree should be built on the basis of high-quality input data elaborated with the help of the main phylogenetic methods (such as Neighbor-joining, Bayesian MCMC, and Maximum parsimony), and ancestral character states, allowing us to reveal a certain number of homoplastic characters. Secondly, after the detected instances of homoplasy are eliminated from the input matrix, the consensus tree is to be compiled again. It is expected that after homoplastic optimization it will be possible to better resolve individual “problem clades”, and generally the homoplasy-optimized phylogeny should be more robust than the tree constructed initially. The proposed procedure is tested on the 110-item Swadesh wordlists of the Lezgian and Tsezic groups. The Lezgian and Tsezic results generally support theoretical expectations. The MLN (minimal lateral network) method, currently implemented in the LingPy software, is a helpful tool for the detection of linguistic homoplasy.
“Just don’t be creepy”: A phenomenological study of the experiences of men in massage therapy
Authors: Baskwill Amanda , Vanstone Meredith 
Published: November 2017

Abstract

Background
Societal expectations around traditional binary gender roles result in some professions being considered “men’s work” or “women’s work”. Massage therapy (MT) is one such profession that, despite being predominantly female, is joined by an increasing number of men with a desire to help others.

Methods
This descriptive phenomenological study asked male massage therapists in Ontario, Canada, about their experience of gender in their professional lives. Fourteen men shared their experiences of practice, which included discriminatory hiring and patient preferences for female practitioners. These issues resulted in difficulty establishing a clinical practice. To create a successful practice, men described the need for professionalism, clear communication, and a comfortable treatment environment.

Results and conclusions
Researchers should explore the impact of discrimination on men in MT, patient preferences based on the therapist’s gender, and the role of education in perpetuating societal heterosexual norms. Finally, as with any shift in culture, all levels of organization must take action to remove discrimination and bias within the profession of MT.

Applicability of DFT model in reactive distillation
Authors: Staszak Maciej 
Published: November 2017

AbstractThe density functional theory (DFT) applicability to reactive distillation is discussed. Brief modeling techniques description of distillation and rectification with chemical reaction is provided as a background for quantum method usage description. The equilibrium and nonequilibrium distillation models are described for that purpose. The DFT quantum theory is concisely described. The usage of DFT in the modeling of reactive distillation is described in two parts. One of the fundamental and very important component of distillation modeling is vapor-liquid equilibrium description for which the DFT quantum approach can be used. The representative DFT models, namely COSMO-RS (Conductor like Screening Model for Real Solvents), COSMOSPACE (COSMO Surface Pair Activity Coefficient) and COSMO-SAC (SAC – segment activity coefficient) approaches are described. The second part treats the way in which the chemical reaction is described by means of quantum DFT method. The intrinsic reaction coordinate (IRC) method is described which is used to find minimum energy path of substrates to products transition. The DFT is one of the methods which can be used for that purpose. The literature data examples are provided which proves that IRC method is applicable for chemical reaction kinetics description.
Methodeutic and the order of inquiry
Authors: Bergman Mats 
Published: November 2017

AbstractAlthough C. S. Peirce frequently notes the importance of the branch of logic he designates “rhetoric” or “methodeutic,” he only rarely specifies what this subdivision is meant to involve. This article reassesses the role of methodeutic in Peirce’s classification of the sciences, as well as the methodical significance of this classificatory endeavor itself. The article argues that the classification of sciences is best comprehended as a distinctive phase of methodeutic investigation, which examines actual manifestations of inquiry as well as abstract principles in crafting a normatively guiding conception of the scientific venture. It is further argued that the strict hierarchy on which Peirce bases his classification needs to be tempered to allow for a more flexible ordering, in which so-called “dynamical relationships” between inquiries are considered alongside the top-down perspective of “rational precedence.”

Abstract
Minahan, CL, Poke, DP, Morrison, J, and Bellinger, PM. Muscle damage and metabolic responses to repeated-sprint running with and without deceleration. J Strength Cond Res 34(12): 3423–3430, 2020—This study aimed to determine whether repeated-sprint running with deceleration aggravates markers of muscle damage or delays the recovery of performance compared with repeated-sprint running without deceleration. Fourteen male team-sport athletes performed 2 randomly ordered testing sessions on a nonmotorized treadmill with one session requiring subjects to decelerate (TMd) within 4 seconds before stopping or immediately step to the side of the treadmill belt at the completion of each sprint (TMa). Peak and mean velocities, speed decrement, blood lactate concentrations, and oxygen uptake were monitored during the repeated-sprint running protocols. Countermovement vertical jump (CMJ) performance, perceived muscle soreness, sit-and-reach flexibility, plasma creatine kinase (CK), lactate dehydrogenase (LDH), and myoglobin (Mb) concentrations were quantified immediately before and after and 45 minutes, 24 and 48 hours after repeated-sprint running protocols. Although muscle damage was indicated by increases in CK, LDH, and Mb (p ≤ 0.05) in both groups, there was no significant effect of condition (TMa vs. TMd) on any of the measured performance or physiological variables (p > 0.05). The present study indicated that the removal of deceleration from repeated-sprint running on a nonmotorized treadmill has no effect on metabolism or performance during or after repeated-sprint running or markers of muscle damage.
