Abstract
This study evaluated the effect of xylanase supplementation (with or without), feeding method (dry or liquid), and feedstuff (corn distiller's dried grains with solubles [DDGS] or wheat middlings) on apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID) of GE and nutrients, intestinal morphology, ileal and cecal pH, and VFA concentrations. Sixty-four growing pigs (25.87 ± 0.38kg initial BW) were blocked by BW and sex and randomly assigned to 8 dietary treatments. Within each feedstuff, diets were fed either liquid or dry, without or with xylanase (24,000 birch xylan units/kg feed), for 16 d. Diets contained 3.32 and 3.19 Mcal/kg ME for DDGS- and wheat middlings-based diets, respectively. Pigs were fed restricted at 3 times maintenance ME requirements. Liquid diets were prepared by steeping DDGS or wheat middlings with water (1:3, wt/vol) with or without xylanase for 24 h followed by mixing with a basal ingredient mixture and water to achieve a final ratio of 1:2.5 (wt/vol). During steeping of wheat middlings, some fiber degradation occurred. When xylanase was added in dry wheat middlings diets, AID of GE ( < 0.10) and NDF ( < 0.05) increased compared with dry wheat middlings diets without xylanase (64.50 vs. 54.67% and 52.88 vs. 31.69%, respectively), but supplementation of xylanase did not impact AID of GE and NDF when liquid wheat middlings diets were fed. Xylanase in liquid DDGS diets increased ( < 0.05) the AID of NDF compared with liquid DDGS diets without xylanase, but xylanase did not affect AID of NDF in dry DDGS diets. Xylanase in wheat middlings diets improved ( < 0.05) ATTD of GE and N compared with wheat middlings diets without xylanase (80.37 vs. 78.07% and 80.23 vs. 77.94%, respectively). However, there was no effect of xylanase in DDGS diets. Pigs fed DDGS diets had greater concentrations of butyrate in the cecum ( = 0.001) than pigs fed wheat middlings diets (27.6 vs. 20.4 mmol/L). Pigs fed DDGS diets with xylanase had deeper crypts ( < 0.05) in the jejunum than pigs fed DDGS diets without xylanase (98.20 vs. 86.16 μm), but xylanase had no effect in pigs fed wheat middlings diets. Results suggest that liquid feeding and xylanase supplementation had limited potential to enhance nutrient digestibility in pigs fed DDGS-based diets. However, xylanase supplementation in dry wheat middlings-based diets improved the AID of NDF and ATTD of GE and N, but liquid feeding as pretreatment did not further enhance the nutritional value of wheat middlings-based diets.

Abstract
Background Athletic groin pain (AGP) is prevalent in sports involving repeated accelerations, decelerations, kicking and change-of-direction movements. Clinical and radiological examinations lack the ability to assess pathomechanics of AGP, but three-dimensional biomechanical movement analysis may be an important innovation. Aim The primary aim was to describe and analyse movements used by patients with AGP during a maximum effort change-of-direction task. The secondary aim was to determine if specific anatomical diagnoses were related to a distinct movement strategy. Methods 322 athletes with a current symptom of chronic AGP participated. Structured and standardised clinical assessments and radiological examinations were performed on all participants. Additionally, each participant performed multiple repetitions of a planned maximum effort change-of-direction task during which whole body kinematics were recorded. Kinematic and kinetic data were examined using continuous waveform analysis techniques in combination with a subgroup design that used gap statistic and hierarchical clustering. Results Three subgroups (clusters) were identified. Kinematic and kinetic measures of the clusters differed strongly in patterns observed in thorax, pelvis, hip, knee and ankle. Cluster 1 (40%) was characterised by increased ankle eversion, external rotation and knee internal rotation and greater knee work. Cluster 2 (15%) was characterised by increased hip flexion, pelvis contralateral drop, thorax tilt and increased hip work. Cluster 3 (45%) was characterised by high ankle dorsiflexion, thorax contralateral drop, ankle work and prolonged ground contact time. No correlation was observed between movement clusters and clinically palpated location of the participant's pain. Conclusions We identified three distinct movement strategies among athletes with long-standing groin pain during a maximum effort change-of-direction task These movement strategies were not related to clinical assessment findings but highlighted targets for rehabilitation in response to possible propagative mechanisms. Trial registration number NCT02437942, pre results.

Abstract
The initial step in developing injury prevention strategies is to establish the epidemiology of injury. However there has been no published research on injury in Gaelic handball. This study describes the epidemiology of injury in 75 Gaelic handball players utilising a retrospective questionnaire. 88% of participants reported one or more injuries. Injuries to the upper limb were prevalent (52.9%), followed by the lower limb (30.3%). The shoulder (17.6%), finger (10.5%) and ankle (9.8%) were the primary sites of injury. Injuries occurred most frequently in December (9.7%), January (9.7%), February (9.7%) and November (8.7%). Injuries predominantly occurred during games (82.4%). Injuries were primarily severe (54.7%), with 14.6% of participants admitted to hospital due to injury. Given that this is the only study on Gaelic handball to date, prospective epidemiological studies and further research on injury prevention strategies are necessary.

Abstract
PURPOSE Incident investigation, reporting, and learning are core elements of quality improvement in radiation treatment. This report describes the development of a Canadian National System for Incident Reporting in Radiation Treatment (NSIR-RT), focusing especially on the taxonomy. METHODS AND MATERIALS The NSIR-RT was developed to provide a framework in Canada for reporting and analyzing radiation treatment incidents. A key objective was to assure compatibility with other international reporting systems to facilitate future information exchange. The Canadian community was engaged at every step of the development process through Delphi consensus building and inter-user agreement testing to promote awareness of the system and motivate broad-based utilization across the country. RESULTS The final taxonomy was comprised of 6 data groups (impact, discovery, patient, details, treatment delivery, and investigation) and 33 data categories with predefined menu options. There was a high level agreement within the Canadian community about the final suite of data categories, and broad alignment of these categories with the World Health Organization and other American and European radiation treatment incident classifications. CONCLUSIONS The Canadian NSIR-RT taxonomy will be implemented as an online, web-based reporting and analysis system. It is expected that the taxonomy will evolve and mature over time to meet the changing needs of the Canadian radiation treatment community and support radiation treatment incident learning on a global scale.

Abstract
Quality is a ubiquitous term in medical radiation technology; technologists, programs, and organizations emphasize the importance of "quality care," yet the concept of what is encompassed by the term, how it is built and measured, and who is the judge of whether it has been achieved, are often left undefined. This article will present theoretical definitions of quality, considering the value of professional, patient, and organization perspectives. Foundational quality principles and frameworks will be explored to highlight tools necessary to engage in "quality-related" activities and research at the individual, institutional, and systems level. Being equipped with an understanding of the work of Deming, the underpinnings of the lean strategy and the idea of continuous quality improvement will support technologists in contributing to evidence-based, high-quality, and safe practice. Building on these basics, concepts of complexity and standardization will be explored as they relate to achieving and maintaining quality given changing practice, focusing on personalized medicine, technological innovation, and best practice guidelines. Means to measure and evaluate quality will be presented, emphasizing the need for a structured approach. Using the work of the Canadian Partnership for Quality Radiotherapy as an example, key quality-related considerations, such as incident reporting, organizational structure, and quality culture will be discussed, with specific attention to roles within the team. When appropriately defined, measured, and evaluated, the quest for quality has the potential to improve safety and mitigate risk. Engaging technologists to assume strong roles in providing the highest quality of care will contribute positively at the level of the individual patient, the organization, and the system.

Abstract
Study Design Systematic review. Objective Determine whether closed suction wound drains decrease the incidence of postoperative complications compared with no drain use in patients undergoing spine surgery for lumbar degenerative conditions. Methods Electronic databases and reference lists of key articles were searched up through January 22, 2015, to identify studies comparing the use of closed suction wound drains with no drains in spine surgery for lumbar degenerative conditions. Outcomes assessed included the cumulative incidence of epidural hematoma, superficial and deep wound infection, and postoperative blood transfusion. The overall strength of evidence across studies was based on precepts outlined by the Grades of Recommendation Assessment, Development and Evaluation Working Group. Results Five heterogeneous studies, three randomized controlled trials, and two cohort studies form the evidence basis for this report. There was no difference in the incidence of hematoma, superficial wound infection, or deep infection in patients with compared with patients without closed suction wound drains after lumbar surgery. The upper bounds of the 95% confidence interval for hematoma ranged from 1.1 to 16.7%; for superficial infection, 1.0 to 7.3%; and for deep infection, 1.0 to 7.1%. One observational study reported a 3.5-fold increase in the risk of blood transfusion in patients with a drain. The overall strength of evidence for these findings is considered low or insufficient. Conclusions Conclusions from this systematic review are limited by the quality of included studies that assessed the use of closed suction wound drains in lumbar spine surgeries for degenerative conditions. We believe that spine surgeons should not routinely rely on closed suction wound drains in lumbar spine surgery until a higher level of evidence becomes available to support its use.

Abstract
This is a proof‐of‐concept study demonstrating the capacity for modulated electron radiation therapy (MERT) dose distributions using 3D printed bolus. Previous reports have involved bolus design using an electron pencil beam model and fabrication using a milling machine. In this study, an in‐house algorithm is presented that optimizes the dose distribution with regard to dose coverage, conformity, and homogeneity within the planning target volume (PTV). The algorithm takes advantage of a commercial electron Monte Carlo dose calculation and uses the calculated result as input. Distances along ray lines from the distal side of 90% isodose line to distal surface of the PTV are used to estimate the bolus thickness. Inhomogeneities within the calculation volume are accounted for using the coefficient of equivalent thickness method. Several regional modulation operators are applied to improve the dose coverage and uniformity. The process is iterated (usually twice) until an acceptable MERT plan is realized, and the final bolus is printed using solid polylactic acid. The method is evaluated with regular geometric phantoms, anthropomorphic phantoms, and a clinical rhabdomyosarcoma pediatric case. In all cases the dose conformity are improved compared to that with uniform bolus. For geometric phantoms with air or bone inhomogeneities, the dose homogeneity is markedly improved. The actual printed boluses conform well to the surface of complex anthropomorphic phantoms. The correspondence of the dose distribution between the calculated synthetic bolus and the actual manufactured bolus is shown. For the rhabdomyosarcoma patient, the MERT plan yields a reduction of mean dose by 38.2% in left kidney relative to uniform bolus. MERT using 3D printed bolus appears to be a practical, low‐cost approach to generating optimized bolus for electron therapy. The method is effective in improving conformity of the prescription isodose surface and in sparing immediately adjacent normal tissues. PACS number: 81.40.Wx

Abstract
The Dominican Republic (DR) and Haiti share the island of Hispaniola, and reportable transboundary animal diseases have been introduced between the two countries historically. Outbreaks of severe teschovirus encephalomyelitis in pigs began occurring in Haiti in February 2009, and a field and laboratort study in April 2010 indicated that the teschovirus disease is prevalent in many regions in Haiti including areas near the border with DR and that other viral disease agents, including CSF virus (CSFV), porcine circovirus type 2 (PCV-2), porcine reproductive and respiratory syndrome virus (PRRSV), and swine influenza virus (SIV), are present in the swine population in these regions. The purpose of this study was to evaluate the introduction of teschovirus encephalomyelitis from Haiti to DR and to identify the other viral disease agents present in the swine population in regions of DR near the border with Haiti. Six of 7 brains and 6 of 7 spinal cords collected from pigs with central nervous system (CNS) signs were positive in reverse transcription-polymerase chain reaction for PTV. Genome sequencing on the Dominican PTV and phylogenetic analysis on the polyprotein of PTV strains indicate that the sequence of the Dominican PTV is 99.1% identical to the Haitian isolate and closely related to other PTV-1 strains in the world. Among 109 serum samples tested, 65 (59.6%) were positive for antibodies to PCV-2, and 51 (46.8%) were positive for antibodies to CSFV. Fifty-four of the 109 serum samples were tested for antibodies to other agents. Among the 54 samples, 20 (37.0%) were seropositive to PTV-1, 17 (31.5%) tested seropositive to SIV H3N2, 12 (22.2%) were seropositive to SIV H1N1, and 1 (1.9%) was seropositive to PRRSV.

Abstract
The epidemiological situation of foot-and-mouth disease virus (FMDV) is uncertain in Nigeria, where the disease is endemic, and the majority of outbreaks are unreported. Control measures for FMD in Nigeria are not being implemented due to the absence of locally produced vaccines and an official ban on vaccine importation. This study summarizes the findings of a 3-year study aimed at quantifying the seroprevalence of FMD, its distribution in susceptible species and the genetic diversity of FMDV isolated from the Plateau State of Nigeria. A 29% FMD prevalence was estimated using 3ABC enzyme-linked immunosorbent assay (3ABC ELISA). Farms with suspected FMD nearby, with contact with wildlife, that used drugs or FMD vaccines or with >100 animals, and animals of large ruminant species and in pastures other than nomadic grazing were significantly (P < 0.05) associated with FMD. Antibodies against five FMDV serotypes, (A, O, SAT1, SAT2 and SAT3) were detected by the virus neutralization test (VNT) at various titres (<100->800) from all tested sera from most parts of the region. This is probably the first report of the presence of FMDV SAT3 in Nigeria. Further studies to investigate the potential probable presence and prevalence of SAT 3 virus in Nigeria are required. Tissue samples collected from clinical animals were positive for FMDV. Virus isolates were sequenced and confirmed as serotype A. All of the isolates showed marked genetic homogeneity with >99% genetic identity in the VP1 region and were most closely related to a previously described virus collected from Cameroon in 2000. This study provides knowledge on the epidemiological situation of FMD in Plateau State, Nigeria, and will probably help to develop effective control and preventive strategies for the disease in Nigeria and other countries in the West African subregion.

Abstract
BACKGROUND Neutrophils accumulate in the airways of horses with heaves. They likely play an important role in the disease pathogenesis. Understanding the pathways regulating their migration may help identifying new therapeutic targets. HYPOTHESIS MAPK and PI3K pathways are involved in neutrophil migration toward the airway lumen in heaves. ANIMALS Twelve heaves-affected horses and 4 healthy horses. METHODS Migratory activity of bronchoalveolar lavage fluids (BALF) from horses with heaves and healthy horses was compared by means of a Boyden chamber. Involvement of MAPK and PI3K pathways in neutrophil migration was investigated by pretreating neutrophils with inhibitors of p38 MAPK, JNK, MEK1/2, and PI3K. The capacity of a p38 MAPK inhibitor at decreasing neutrophil chemotaxis toward the airways was also evaluated in vivo. RESULTS BALF from symptomatic heaves-affected horses induced a greater degree of chemokinesis (P = .0004) than BALF from healthy horses. Although all pathways tested were involved in neutrophil migration, inhibition of PI3K was most potent in vitro. An inhibitor of p38 MAPK administered before challenge in horses with heaves did not alter BALF chemokinetic properties. BALF neutrophil percentage and BALF migratory activity were positively correlated after 14 and 35 days of antigen challenge in healthy (P = .05; R(2) = 0.82) and heaves-affected horses (P = .03; R(2) = 0.76), respectively. CONCLUSIONS AND CLINICAL IMPORTANCE MAPK and PI3K pathways regulate neutrophil migration induced by BALF of horses with heaves. Inhibition of multiple pathways might be required to completely abolish BALF-induced neutrophil migratory activity and possibly inflammation in heaves.
