Background: Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction among athletes. Although arthroscopic surgery is an established treatment option for FAI, there are few studies reporting detailed outcomes using validated outcome measurements specifically designed for young and active athletes. Purpose: To report outcomes 1 year after arthroscopic treatment of FAI in top-level athletes using validated outcome measurements adapted for a young and active population. Study Design: Case series; Level of evidence, 4. Methods: A total of 85 top-level athletes (68 males, 17 females) with a mean (±SD) age of 25 ± 5 years underwent arthroscopic surgery for FAI. All athletes who reported Hip Sports Activity Scale (HSAS) levels 7 or 8 (range, 0-8) prior to symptom onset were included. The cohort was prospectively evaluated using online web-based validated health-related patient-reported outcomes measures (HR-PROMs), including the short version of the International Hip Outcome Tool (iHOT-12), the Copenhagen Hip and Groin Outcome Score (HAGOS; 6 subscales), the EuroQOL 5 dimensions questionnaire (EQ-5D; 2 subscales), the Hip Sports Activity Scale (HSAS) for physical activity level, and a visual analog scale (VAS) for overall hip function. Furthermore, patients reported their overall satisfaction with treatment. Results: The mean follow-up time was 12.3 ± 0.6 months. Preoperative scores compared with those obtained at the 12-month follow-up revealed statistically and clinically significant improvements ( P < .0001) for all measured outcomes: iHOT-12 (42 vs 73), VAS for global hip function (52 vs 77), HSAS (4.3 vs 5.7), EQ-5D index (0.60 vs 0.83), EQ-VAS (68 vs 82), and HAGOS subscales (60 vs 83, 50 vs 73, 66 vs 86, 39 vs 75, 27 vs 70, and 34 vs 67). At the 12-month follow-up, 79 athletes (93%) reported that they were satisfied with the outcome of surgery. At follow-up, 62 athletes (73%) had returned to competitive sports (HSAS levels 5-8) and 44 (52%) to their previous HSAS level of activity (HSAS level 7 or 8). Twenty-three athletes (27%) did not return to competitive sports (HSAS level ≤4). Significantly lower levels of return to sports were seen with longer symptom duration ( P < .05). Conclusion: Twelve months after surgery, arthroscopic treatment for FAI in top-level athletes resulted in statistically and clinically significant improvements at the group level in all outcome parameters for pain, symptoms, function, physical activity level, quality of life, and general health. One year after surgery, approximately 3 of 4 top-level athletes had returned to sports.

Published: February 2015

AbstractBackgroundFoot deformity, flat feet, and the use of ill‐fitting footwear are common in children and adolescents with Down syndrome (DS). The aim of this study was to determine whether these observations are associated with foot‐specific disability in this group.MethodsA cross‐sectional study design. Foot structure (foot posture determined using the Arch Index, presence of hallux valgus and lesser toe deformities) and footwear fit (determined by length and width percentage differences between the participant's foot and footwear) were assessed in 50 participants with DS (22 females, 28 males) aged five to 18 with a mean (SD) age of 10.6 (3.9) years. Foot‐specific disability was determined using the parent‐reported Oxford Ankle Foot Questionnaire for Children (OxAFQ‐C). Associations between foot structure and footwear fit with the four domains (Physical, School and play, Emotional and Footwear) of the OxAFQ‐C were determined using multivariate regression modelling.ResultsThe mean (SD) Arch Index was 0.29 (0.08), and the prevalence of flat feet, hallux valgus and lesser toe deformities was 76%, 10% and 12% respectively. Few participants wore footwear that was too short (10%), but the use of footwear that was too narrow was common (58%). The presence of hallux valgus was significantly associated with increased disability for the OxAFQ‐C School and play domain scores. The use of narrow‐fitting footwear was significantly associated with increased levels of disability for the OxAFQ‐C Physical, School and play, and Emotional domains. However, these variables only explained between 10% to 14% of the variance in the OxAFQ‐C domain scores. There were no significant associations between foot structure and footwear fit with the OxAFQ‐C Footwear domain scores.ConclusionsFlatter feet and lesser toe deformities are not associated with foot‐specific disability in children and adolescents with DS. Hallux valgus is associated with foot‐specific disability during school and play activities. Ill‐fitting footwear (too narrow) is common and is associated with foot‐specific disability. Further research is required to identify if the relationship between narrow‐fitting footwear and foot‐specific disability is causal, and to identify other factors associated with foot‐specific disability in children and adolescents with DS.

Abstract
Introduction
Previous studies in animal models of osteoarthritis suggest that alendronate (ALN) has antiresorptive and chondroprotective effects, and can reduce osteophyte formation. However, these studies used non-physiologic injury methods, and did not investigate early time points during which bone is rapidly remodeled prior to cartilage degeneration. The current study utilized a non-invasive model of knee injury in mice to investigate the effect of ALN treatment on subchondral bone changes, articular cartilage degeneration, and osteophyte formation following injury.

Methods
Non-invasive knee injury via tibial compression overload or sham injury was performed on a total of 90 mice. Mice were treated with twice weekly subcutaneous injections of low-dose ALN (40 μg/kg/dose), high-dose ALN (1,000 μg/kg/dose), or vehicle, starting immediately after injury until sacrifice at 7, 14 or 56 days. Trabecular bone of the femoral epiphysis, subchondral cortical bone, and osteophyte volume were quantified using micro-computed tomography (μCT). Whole-joint histology was performed at all time points to analyze articular cartilage and joint degeneration. Blood was collected at sacrifice, and serum was analyzed for biomarkers of bone formation and resorption.

Results
μCT analysis revealed significant loss of trabecular bone from the femoral epiphysis 7 and 14 days post-injury, which was effectively prevented by high-dose ALN treatment. High-dose ALN treatment was also able to reduce subchondral bone thickening 56 days post-injury, and was able to partially preserve articular cartilage 14 days post-injury. However, ALN treatment was not able to reduce osteophyte formation at 56 days post-injury, nor was it able to prevent articular cartilage and joint degeneration at this time point. Analysis of serum biomarkers revealed an increase in bone resorption at 7 and 14 days post-injury, with no change in bone formation at any time points.

Conclusions
High-dose ALN treatment was able to prevent early trabecular bone loss and cartilage degeneration following non-invasive knee injury, but was not able to mitigate long-term joint degeneration. These data contribute to understanding the effect of bisphosphonates on the development of osteoarthritis, and may support the use of anti-resorptive drugs to prevent joint degeneration following injury, although further investigation is warranted.
A review on stochastic approach for dynamic power management in wireless sensor networks
Authors: Pughat Anuradha , Sharma Vidushi 
Published: February 2015

AbstractWireless sensor networks (WSNs) demand low power and energy efficient hardware and software. Dynamic Power Management (DPM) technique reduces the maximum possible active states of a wireless sensor node by controlling the switching of the low power manageable components in power down or off states. During DPM, it is also required that the deadline of task execution and performance are not compromised. It is seen that operational level change can improve the energy efficiency of a system drastically (up to 90%). Hence, DPM policies have drawn considerable attention. This review paper classifies different dynamic power management techniques and focuses on stochastic modeling scheme which dynamically manage wireless sensor node operations in order to minimize its power consumption. This survey paper is expected to trigger ideas for future research projects in power aware wireless sensor network arenas.
Determinants for the transition from work into retirement in Europe
Authors: Riedel Monika , Hofer Helmut , Wögerbauer Birgit 
Published: February 2015

Abstract
We use the labor force ad hoc module “transition from work into retirement” to analyze the link between individual as well as pension system characteristics and planned retirement age within the European Union. We find that timing of retirement is correlated between partners who are, already at the stage of retirement planning. In richer countries of the EU15, standard retirement age seems to have a larger effect on planned retirement age than in poorer EU15 states or in new EU member states. The effect of pension wealth is largest in the new EU member states and smallest in rich EU15 countries. Furthermore, industry and occupation effects differ by country type.
BIM based collaborative and interactive design process using computer game engine for general end-users
Authors: Edwards Gareth , Li Haijiang , Wang Bin 
Published: February 2015

Abstract

Background
The emerging Building Information Modelling (BIM) in the Architectural, Engineering and Construction (AEC)/Facility Management (FM) industry promotes life cycle process and collaborative way of working. Currently, many efforts have been contributed for professional integrated design/construction/maintenance process, there are very few practical methods that can enable a professional designer to effectively interact and collaborate with end-users/clients on a functional level.

Method
This paper tries to address the issue via the utilisation of computer game software combined with Building Information Modelling (BIM). Game-engine technology is used due to its intuitive controls, immersive 3D technology and network capabilities that allow for multiple simultaneous users. BIM has been specified due to the growing trend in industry for the adoption of the design method and the 3D nature of the models, which suit a game engine’s capabilities.

Results
The prototype system created in this paper is based around a designer creating a structure using BIM and this being transferred into the game engine automatically through a two-way data transferring channel. This model is then used in the game engine across a number of network connected client ends to allow end-users to change/add elements to the design, and those changes will be synchronized back to the original design conducted by the professional designer. The system has been tested for its robustness and functionality against the development requirements, and the results showed promising potential to support more collaborative and interactive design process.

Conclusion
It was concluded that this process of involving the end-user could be very useful in certain circumstances to better elaborate the end user’s requirement to design team in real time and in an efficient way.
Topographical distribution of blubber in finless porpoises (Neophocaena asiaeorientalis sunameri): a result from adapting to living in coastal waters
Authors: Zeng Xianyuan , Ji Junhua , Hao Yujiang , Wang Ding 
Published: February 2015

AbstractBackgroundBlubber has many functions, among which energy storage, thermoregulation, buoyancy, and hydrodynamic streamlining are the most frequently cited. Within and between taxa, variations in its structure and distribution likely reflect different adaptations of a species to its life history requirements, environment, health, and function. Here, we use ultrasound to describe the distribution of blubber in the finless porpoise (Neophocaena asiaeorientalis sunameri) based on examinations of 34 fresh cadavers recovered as accidental fisheries bycatch.ResultsMeasurements of blubber depth determined by ultrasound positively correlated with conventional measurements using a scalpel and calipers. Whereas conventional surgical incision and visual examination revealed two layers of blubber, ultrasound revealed up to three layers; thus, ultrasound reveals additional structural detail in blubber while crude necropsy techniques do not. Across life history categories, ultrasound revealed the distribution of inner blubber to be topographically consistent with that of full-depth blubber. Blubber in the dorsal region was stratified into three layers and was significantly thicker than that in the lateral and ventral regions, in which a middle layer was normally absent.ConclusionsUltrasound provides a fast, effective, and accurate means to determine blubber thickness and structure, and thus, assessment of the health of fresh finless porpoise carcasses. Blubber depth is determined largely by the thickness of the inner and middle layers, wherein lipids are concentrated. The thickening of blubber in the dorsal thoracic-abdominal region suggests multiple roles of thermal insulation, lipid storage, and, we speculate, to facilitate vertical stability in the complex shallow and estuarine waters in which this animal absent of a dorsal fin occurs.
Platelet-rich plasma to treat ankle cartilage pathology - from translational potential to clinical evidence: a systematic review
Authors: Vannini Francesca , Di Matteo Berardo , Filardo Giuseppe 
Published: February 2015

Abstract
Platelet-rich Plasma (PRP) is a fascinating biological treatment showing promising results for the management of cartilage disorders. However, despite the step forwards in this research area and the increasing use of PRP in clinical practice, its use remains still controversial and especially its application as injective treatment for ankle cartilage pathology have been scarcely investigated.
The aim of this paper is to describe the translational evidence for the use of PRP in cartilage treatment and to systematically review all the available evidence regarding the clinical application of PRP for ankle cartilage disorders, in order to understand what is the current state of the art for this specific clinical indication, underlining both limits and potential of this biological strategy.
A systematic review of the clinical literature was performed on the use of PRP to treat ankle cartilage disorders and 7 papers were identified. PRP has been used in two different ways: 5 of the available papers focus on its use as an augmentation procedure to various surgical techniques for cartilage regeneration, while only two studies report its conservative application through intra-articular injections. Based on the limited number of clinical studies available on this topic, this systematic review showed the lack of major adverse events related to PRP and overall good results for the treatment of ankle cartilage pathology, thus confirming the translational potential of this biological treatment suggested by several preclinical studies. Further high quality clinical trials in the ankle are still needed to clarify proper indications and best applicative modalities.

Published: February 2015

AbstractThis study examines phylogenetic relationships among the 12 genera of Urticeae (Urticaceae) and investigates the pattern of morphological evolution based on analysis of nuclear ribosomal internal transcribed spacer (nrITS) and two plastid DNA regions (rbcL exon, trnL‐F spacer). Sequence data were analyzed using maximum parsimony and Bayesian inference, and selected morphological traits were mapped onto the molecular tree. The molecular results strongly supported monophyly of Urticeae, excluding Gyrotaenia, which is related to Elatostemateae. All genera were monophyletic except for Urtica, Laportea, and Urera. Two Hesperocnide species are nested within Urtica. Laportea and Urera are divided into three groups with a strong geographical signal. The inferred phylogeny indicates five well‐supported clades in Urticeae: clade A including Urtica (with Hesperocnide), Zhengyia, Laportea I, and Nanocnide; clade B comprising Dendrocnide and Discocnide; clade C including only Girardinia; clade D including Laportea II; and clade E including Obetia, Urera I, II, III, and Poikilospermum. Although it is difficult to identify morphological synapomorphies for these well‐defined clades within Urticeae, character analysis shows that the herbaceous habit and alternate leaves are the ancestral states in the tribe. The presence of stinging hairs is the derived status in Urticeae, and it might have been a key innovation triggering species diversification in the tribe.
Optimal Advance Scheduling
Authors: Truong Van-Anh 
Published: February 2015

The dynamic assignment of patients to exam days in order to manage daily variations in demand and capacity is a long-standing open research area in appointment scheduling. In particular, the dynamic assignment of advance appointments has been considered to be especially challenging because of its high dimensionality. We consider a canonical model of dynamic advance scheduling with two patient classes: an urgent demand class, which must be served on the day of arrival, and a regular demand class, which can be served at a future date. Patients take the earliest appointments offered and do not differentiate among providers. We derive a surprising characterization of an optimal policy and an algorithm to compute the policy exactly and efficiently. These are, to our knowledge, the first analytical results for the dynamic advance assignment of patients to exam days. We introduce the property of successive refinability, which allows advance schedules to be easily computable and under which there is no cost to the system to making advance commitments to patients. We allow multiple types of capacity to be considered and both demand and capacity to be nonstationary and stochastic. This paper was accepted by Martin Lariviere, operations management.
Adapting Practice-Based Intervention Research to Electronic Environments:
Opportunities and Complexities at Two Institutions
Authors: Stille Christopher J. , Lockhart Steven A. , Maertens Julie A. , Madden Christi A. , Darden Paul M. 
Published: February 2015

Background and Purpose: Primary care practice-based research has become more
complex with increased use of electronic health records (EHRs). Little has been reported
about changes in study planning and execution that are required as practices change from
paper-based to electronic-based environments. We describe the evolution of a pediatric
practice-based intervention study as it was adapted for use in the electronic
environment, to enable other practice-based researchers to plan efficient, effective
studies.Methods: We adapted a paper-based pediatric office-level intervention to enhance
parent-provider communication about subspecialty referrals for use in two practice-based
research networks (PBRNs) with partially and fully electronic environments. We
documented the process of adaptation and its effect on study feasibility and efficiency,
resource use, and administrative and regulatory complexities, as the study was
implemented in the two networks.Results: Considerable time and money was required to
adapt the paper-based study to the electronic environment, requiring extra meetings with
institutional EHR-, regulatory-, and administrative teams, and increased practice
training. Institutional unfamiliarity with using EHRs in practice-based research, and
the consequent need to develop new policies, were major contributors to delays. Adapting
intervention tools to the EHR and minimizing practice disruptions was challenging, but
resulted in several efficiencies as compared with a paper-based project. In particular,
recruitment and tracking of subjects and data collection were easier and more
efficient.Conclusions: Practice-based intervention research in an electronic environment
adds considerable cost and time at the outset of a study, especially for centers
unfamiliar with such research. Efficiencies generated have the potential of easing the
work of study enrollment, subject tracking, and data collection.

On the Influences of Adjacent Conducting Media and Coil Frequency on the Electromagnetic Field and Flow Characteristics in Solidifying Melts
Authors: Poole Gregory , Nastac Laurentiu 
Published: February 2015

AbstractThis paper examines the electromagnetic and flow field modification caused by the placement of electrically conducting media in the vicinity of the coil and molten metal and the corresponding influences of coil operating frequency. The electromagnetic field characteristics were numerically calculated using the mutual inductance technique. An improved dual-zone model was employed to describe flow behavior in the mushy region, and accounts for flow damping via interactions between the crystallites and the turbulent eddies. Calculations were performed for unidirectional solidification of an Al-4.5 wt% Cu alloy in a bottom-chill mold undergoing EM stirring. It was found that the presence of shields greatly modified the Lorentz force distribution within the melt. This led to noteworthy changes in the flow directionality, as well as changes in the spatial variation of temperature as solidification progressed. It was also found that these effects were most pronounced at low frequencies. The significance of these findings with respect to solidification process design will be discussed.
