Abstract
Data on the enteric methane emissions of individual cows are useful not just in assisting management decisions and calculating herd inventories but also as inputs for animal genetic evaluations. Data generation for many animal characteristics, including enteric methane emissions, can be expensive and time consuming, so being able to extract as much information as possible from available samples or data sources is worthy of investigation. The objective of the present study was to attempt to predict individual cow methane emissions from the information contained within milk samples, specifically the spectrum of light transmittance across different wavelengths of the mid-infrared (MIR) region of the electromagnetic spectrum. A total of 93,888 individual spot measures of methane (i.e., individual samples of an animal's breath when using the GreenFeed technology) from 384 lactations on 277 grazing dairy cows were collapsed into weekly averages expressed as grams per day; each weekly average coincided with a MIR spectral analysis of a morning or evening individual cow milk sample. Associations between the spectra and enteric methane measures were performed separately using partial least squares regression or neural networks with different tuning parameters evaluated. Several alternative definitions of the enteric methane phenotype (i.e., average enteric methane in the 6 d preceding or 6 d following taking the milk sample or the average of the 6 d before and after the milk sample, all of which also included the enteric methane emitted on the day of milk sampling), the candidate model features (e.g., milk yield, milk composition, and milk MIR) as well as validation strategy (i.e., cross-validation or leave-one-experimental treatment-out) were evaluated. Irrespective of the validation method, the prediction accuracy was best when the average of the milk MIR from the morning and evening milk sample was used and the prediction model was developed using neural networks; concurrently including milk yield and days in milk in the prediction model generated superior predictions relative to just the spectral information alone. Furthermore, prediction accuracy was best when the enteric methane phenotype was the average of at least 20 methane spot measures across a 6-d period flanking each side of the milk sample with associated spectral data. Based on the strategy that achieved the best accuracy of prediction, the correlation between the actual and predicted daily methane emissions when based on 4-fold cross-validation varied per validation stratum from 0.68 to 0.75; the corresponding range when validated on each of the 8 different experimental treatments focusing on alternative pasture grazing systems represented in the dataset varied from 0.55 to 0.71. The root mean square error of prediction across the 4-folds of cross-validation was 37.46 g/d, whereas the root mean square error averaged across all folds of leave-one-treatment-out was 37.50 g/d. Results suggest that even with the likely measurement errors contained within the MIR spectrum and gold standard enteric methane phenotype, enteric methane can be reasonably well predicted from the infrared spectrum of milk samples. What is yet to be established, however, is whether (a) genetic variation exists in this predicted enteric methane phenotype and (b) selection on estimates of genetic merit for this phenotype translate to actual phenotypic differences in enteric methane emissions.

Abstract
AIMS Osteoradionecrosis (ORN) is a serious toxicity of head and neck radiotherapy. It predominantly affects the mandible. Extra-mandibular ORN is rare. The aim of this study was to report the incidence and outcomes of extra-mandibular ORNs from a large institutional database. MATERIALS AND METHODS In total, 2303 head and neck cancer patients were treated with radical or adjuvant radiotherapy. Of these, extra-mandibular ORN developed in 13 patients (0.5%). RESULTS Maxillary ORNs (n = 8) were a consequence of the treatment of various primaries (oropharynx = 3, sinonasal = 2, maxilla = 2, parotid = 1). The median interval from the end of radiotherapy to the development of ORN was 7.5 months (range 3-42 months). The median radiotherapy dose in the centre of the ORN was 48.5 Gy (range 22-66.5 Gy). Four patients (50%) healed in 7, 14, 20 and 41 months. All temporal bone ORNs (n = 5) developed after treatment to the parotid gland (of a total of 115 patients who received radiotherapy for parotid gland malignancy). The median interval from the end of radiotherapy to the development of ORN was 41 months (range 20-68 months). The median total dose in the centre of the ORN was 63.5 Gy (range 60.2-65.3 Gy). ORN healed in only one patient after 32 months of treatment with repeated debridement and topical betamethasone cream. CONCLUSION Extra-mandibular ORN is a rare late toxicity and this current study provides useful information on its incidence and outcome. The risk of temporal bone ORN should be considered in the treatment of parotid malignancies and patients should be counselled. More research is required to determine the optimal management of extra-mandibular ORN, particularly on the role of the PENTOCLO regimen.

Abstract
Abstract
Left atrial appendage occlusion (LAAO) is an established and effective treatment to reduce the risk of thromboembolic stroke derived from the LAA in patient with non valvular atrial fibrillation. Per-cutaneous closure of the LAA is typically guided by fluoroscopic and echocardiographic guidance.
The purpose of our study is to ascertain real world radiation exposure during the LAAO performed in our institution and the interplay of different variables and patient characteristics.
Our study retrospectively analyzed all consecutive LAAO procedures performed at our Tertiary level Teaching Hospital. Data was collected using Hospital electronic records and cardiac catherization laboratory records.
A total of 261 patients who underwent LAAO were identified, 28% were female. Average age at the time of procedure was 77 years (range 54–93 years). Mean fluoroscopy time was 10.2 minutes (±7.0), average Radiation dose was 67 gy/cm2 (±73). Interestingly, gy/cm2 per minute of fluoroscopy averaged at 6.69 (±5.0).
Subgroup analysis focused on the effect of Body mass index (BMI) on radiation dose. Since the recent introduction of a partial electronic health record system, BMI data was only available on 161 patients. The cohort with BMI <30 had a mean radiation dose of 57±62 gy/cm2, whereas for BMI >30 mean dose was 96.8±68, p=0.0025 (95% CI (65 to 14)).
Analysis by the four different device types (Watchman, Watchman Flx, Wavecrest and ACP) were used for LAAO, with highest number been watchman (n=189). Upon comparing the radiation exposure in our study cohort watchman device had the least Dose adjusted Product (DAP) at 62gy/cm2 but the newer watchman flx (n=25) had slightly lower gy/cm2 per minute of fluoroscopy time 6.58±3.41 versus 6.83±5.56.
In addition, operator volume between our two implanters was assessed. Our highest volume operator implanted the majority of devices (n=235) whilst the Watchman Flx was predominantly implanted by our newer implanter (n=26). Despite the relatively modest numbers of the Watchman Flx, there was minimal difference in exposure time in favor of the more senior interventionist.
In conclusion, LAAO in our center has encouraging radiation safety data, which is comparable to previously published data in internationally recognized high volume centers. Normal BMI patients had the least radiation exposure, with the dose increasing with rising BMI.

Abstract
Abstract
Introduction
Self-harm rates in the UK are increasing. Healthcare professionals’ beliefs regarding repeat attendance; attention-seeking; and poor treatment compliance may contribute to patients’ stigma. Self-inflicted burns (SIB) constitute a minority of burns cases, but require disproportionate healthcare input, yet little is known about these patients. Our aim was to evaluate presentations, compliance and outcomes in this patient group.
Method
A retrospective audit of outpatients with SIBs attending a UK Burns Unit over four years (Jan 2016-Dec 2019).
Results
Over the study period, 58 patients presented with 94 burn wounds. Incidence doubled over one year (2018-2019). Most patients were female (85%) with a median age of 29 years (range 19-62). The most commonly associated psychiatric diagnosis was personality disorder. On presentation 22% (n = 21) were admitted under the Mental Health Act. For 83% (n = 48) it was their first presentation with a SIB, although 74% had previously presented with non-burn self-harm. Median burn size was 0.5% TBSA, the most common mechanism was contact (48%) and 77% were deep (n = 77). 92% were compliant with treatment and did not tamper with their wounds or dressings.
Conclusions
The majority, 70% (n = 41), of patients only presented once to the Burns Department during the study period. This challenges the commonly held stereotype that those who self-harm will also seek attention through repeat presentation. Ongoing education among health professionals may dispel some myths regarding these individuals. Further, larger investigations, may permit rigorous comparison of treatment outcomes with non-SIB patients.

Abstract
Abstract
Background
Scaphoid fractures account for 90% carpal injury. Due to the limited vascular supply achieving adequate reduction and healing is important to avoid complications including avascular necrosis. Recent technological advances have led to renewed vigour in bioabsorbable material research to develop devices which could be used without the need for removal and complications including stress shielding and suboptimal imaging.
Method
A systematic review was made using PubMed, Ovid Medline, and Google Scholar databases according to PRISMA guidelines.
Results
Initial search results yielded 852 studies. 124 studies were screened, resulting in 7 studies which were included in this review. The level of evidence of studies ranged between III-IV of low power. Analysis demonstrated mixed findings with generally comparable outcomes to traditionally used screws. Heterogeneity of studies prevented a meta-analysis.
Conclusions
Development in bioabsorbable materials has yielded promising results in orthopaedic studies, however there is a dearth in research using these devices in the scaphoid. Further robust research is needed to establish the efficacy and applicability of bioabsorbable devices in the scaphoid bone.

Abstract
In head and cancer (HNC), osteoradionecrosis (ORN) is one of the most significant complications of radiotherapy (RT). With an absence of effective non-surgical treatment, prevention of the development of ORN is the best approach. The purpose of this study was to identify the risk factors for the development of ORN in HNC. Records of 1,118 patients with HNC treated with radical RT (≥55Gy) from January 2010 to December 2019 were reviewed. After applying the exclusion criteria, 935 patients were included in the final analysis. In patients with confirmed ORN, exact RT doses were mapped. In total, 91 patients were found (9.7%) with a median (range) time of eight (3-89) months to the development of ORN. Smoking, having a primary site in the oropharynx, bone surgery before adjuvant RT, the addition of concurrent chemotherapy, the presence of xerostomia, dental extraction pre-RT, the time ≤20 days between dental extraction and start of RT, and receiving >55Gy RT dose were significant factors for its development. This comprehensive analysis including the precise RT dose mapping has shown the risk factors for the development of ORN. In practice, every effort should be made to avoid these risk factors without compromising the oncology treatment. The findings of this analysis may provide a basis for future prospective research on this topic.

Abstract
Abstract
An AOAC International-International Union of Pure and Applied Chemistry-International Fruit Juice Union (AOAC-IUPAC-IFJU) collaborative study was conducted to evaluate a liquid chromatographic (LC) procedure for determination of patulin in apple juice. Patulin is a mold metabolite found naturally in rotting apples. Patulin is extracted with ethyl acetate, treated with sodium carbonate solution, and determined by reversed-phase LC with UV detection at 254 or 276 nm. Water, water-tetrahydrofuran, or water-acetonitrile was used as mobile phase. Levels determined in spiked test samples were 20, 50,100, and 200 μg/L. A test sample naturally contaminated at 31 μg/L was also included. Twenty-two collaborators in 10 countries analyzed 12 test samples of apple juice. Recoveries averaged 96%, with a range of 91-108%. Repeatability relative standard deviations (RSDr) ranged from 10.9 to 53.8%. The reproducibility relative standard deviation (RSDR) ranged from 15.1 to 68.8%. The LC method for determination of patulin in apple juice has been adopted first action by AOAC INTERNATIONAL.

Abstract
Background Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. Aims To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Methods Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge-EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). Results A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. Conclusions The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers.

Abstract
Wet electrostatic precipitators (WESPs) are modern-era pollution control systems specifically designed to capture ultrafine particles as well as acid mist, highly resistive and sticky particles; however, this requires the use of expensive corrosion-resistant metal alloys. The work presented here is part of a continuing study at Ohio University aimed at reducing the cost of WESPs by using a novel combination of a polymer collector surfaces with a hybrid composite discharge electrode. In this study, a hybrid composite discharge electrode was tested, for the first time, inside a semi-pilot-scale experimental setup, with collection surfaces consists of a vertical array of strands. Particle laden gases were passed through this array of polymer ropes, which were kept wet by a small flow of water. The discharge electrodes were composite laminates of carbon fibers in a polymer matrix enclosing a metal mesh. The preliminary results showed that this new integrated system of composite discharge electrode and polymer collector surfaces can match or exceed the performance of a conventional metal alloy electrostatic precipitator (ESP) with metal discharge electrodes. There are additional advantages due to the system being compact, lightweight, and highly corrosion resistant. Implications: This study focused on integrating and assessing performance of a novel hybrid composite electrode (HCE) inside semi-pilot novel cross-flow electrostatic precipitator at conditions typically observed in coal-fired power plant exhausts. The results were collected for particulate collection efficiencies and were compared with a rigid metal electrode. The HCE outperformed metal electrode by showing higher particulate collection efficiency. This result showcases substantial potential for these two new technologies (HCE and cross-flow system) as a substitute for conventional metal based wet ESPs.

Abstract
In residential care homes and aged-care facilities globally, between one in three and one in four residents may have diabetes, an often complex highly co-morbid illness that leads to frailty, dependency, disability and reduced life expectancy. Residents with diabetes also have a high risk of hypoglycaemia, avoidable hospital admissions, and represent one of the most difficult challenges to health professionals and care staff in optimizing their diabetes and medical care. This detailed review examines the literature relating to care home diabetes over the last 25 years to assess what has been achieved in characterizing residents with diabetes, and what we know about the various but limited intervention studies that have been carried out internationally. The guidance and guidelines that have been published to assist clinicians in planning effective and safe care for this rather vulnerable group of people with diabetes are also reviewed. The review presents the first diagrammatic representation of a likely physiological cascade depicting the mainly irreversible functional decline a resident with diabetes might experience, provides modern principles of care for each resident with diabetes, and identifies what priority recommendations are required to be implemented if diabetes care is to improve. The review concludes that action is required since diabetes care still remains fragmented, sub-optimal, and in need of investment, otherwise care home residents with diabetes will continue to have their needs unfulfilled.

Abstract
Our aim was to examine the clinicopathological features of squamous cell carcinoma (SCC) of the oral cavity and oropharynx in a group of young patients who were dignosed during a 15-year period (2000-2014). Patients' clinical details, risk factors, and survival were obtained from medical records. Formalin-fixed, paraffin-embedded, tissue was tested for high-risk human papillomavirus (HPV). The results were compared with those of a matching group of older patients. We identified 91 patients who were younger than 45 years old, and the 50 youngest patients were studied in detail. The male:female ratio was 2:1, with more tumours located in the oral cavity than in the oropharynx (35 compared with 15). HPV-related SCC was restricted to the oropharynx. When matched for site, stage and HPV status, five-year overall survival was similar in young and matched older patients (log-rank test, p=0.515). Our findings suggest that young patients with oral SCC have a disease profile similar to that of older patients with the condition. It is plausible that prognostic information generally available for oral cancers is applicable to young patients with the disease.

Abstract
BACKGROUND The increased prevalence of multi-drug resistant strains of P.aeruginosa and allergic reactions among adult patients with cystic fibrosis (CF) limits the number of antibiotics available to treat pulmonary exacerbations. Fosfomycin, a unique broad spectrum bactericidal antibiotic, might offer an alternative therapeutic option in such cases. AIM To describe the clinical efficacy, safety and tolerability of intravenous fosfomycin in combination with a second anti-pseudomonal antibiotic to treat pulmonary exacerbations in adult patients with CF. METHOD A retrospective analysis of data captured prospectively, over a 2-years period, on the Unit electronic medical records for patients who received IV fosfomycin was performed. Baseline characteristics in the 12 months prior treatment, lung function, CRP, renal and liver function and electrolytes at start and end of treatment were retrieved. RESULTS 54 patients received 128 courses of IV fosfomycin in combination with a second antibiotic, resulting in improved FEV1 (0.94 L vs 1.24 L, p < 0.01) and reduced CRP (65 mg/L vs 19.3 mg/L, p < 0.01). Renal function pre- and post-treatment remained stable. 4% (n = 5) of courses were complicated with AKI at mid treatment, which resolved at the end of the course. Electrolyte supplementation was required in 18% of cases for potassium and magnesium and 7% for phosphate. Nausea was the most common side effect (48%), but was well controlled with anti-emetics. CONCLUSION Antibiotic regimens including fosfomycin appear to be clinically effective and safe. Fosfomycin should, therefore, be considered as an add-on therapy in patients who failed to respond to initial treatment and with multiple drug allergies.

Abstract
UNLABELLED Over the last few decades, electrostatic precipitators (ESPs) have emerged as effective air pollution control devices for treating coal-fired power plant exhausts. Among the components of the ESP, the discharge electrodes are extremely important in determining the collection efficiency of the ESP. Typically, in wet ESPs, the discharge electrodes used must be made of corrosion-resistant alloys, which makes them extremely expensive and heavy. Hybrid composite discharge electrodes have the potential to be lightweight and corrosion-resistant substitute for traditional metal alloy electrodes used in wet ESPs. In this experimental study, a novel hybrid composite electrode (recently patented at Ohio University) is presented as a substitute for traditional metal electrodes in wet ESPs. The samples of hybrid electrodes were fabricated by using carbon fiber composites, combined with metal mesh, in the shape of a long and thin tape. The electrode's electrical response was evaluated in open atmospheric conditions, while connected to a transformer-rectifier unit to generate a corona current at voltages exceeding 50 kV. Results of these hybrid electrodes were compared with traditional metal electrodes. The hybrid composite discharge electrode produced a uniform corona at comparable power levels to that of metal electrodes, with additional advantages of being compact, lightweight, and highly corrosion resistant. In addition, hybrid composite electrodes exhibited lower corona onset voltage as compared with metal electrodes. The preliminary experimental data are encouraging and show significant potential for this new inexpensive hybrid electrode to replace metal electrodes in wet ESPs, providing comparable (and in some cases exceeding) collection efficiencies with lower ozone generation. IMPLICATIONS The newly invented hybrid composite electrode (HCE) performance was evaluated through experimentation with conventional metal electrodes. The HCE performance was comparable to the metal electrodes. The HCE also exhibited uniform corona fields and steady power while maintaining similar and in some cases superior electrical performance as compared with metal electrodes and thus shows a significant potential to substitute metal electrodes in wet ESP systems.

Abstract
BACKGROUND Assessment presents one of the greatest challenges to evaluating health professional trainee performance, as a result of the subjectivity of judgements and variability in assessor standards. The present study aimed to test a moderation procedure for assessment across four independent universities and explore approaches to assessment and the factors that influence assessment decisions. METHODS Assessment tasks designed independently by each of the four universities to assess student readiness for placement were chosen for the present study. Each university provided four student performance recordings for moderation. Eight different academic assessors viewed the student performances and assessed them using the corresponding university assessment instrument. Assessment results were collated and presented back to the assessors, together with the original university assessment results. Results were discussed with assessors to explore variations. The discussion was recorded, transcribed, thematically analysed and presented back to all assessors to achieve consensus on the emerging major learnings. RESULTS Although there were differences in absolute scores, there was consistency (12 out of 16 performances) in overall judgement decisions regarding placement readiness. Proficient communication skills were considered a key factor when determining placement readiness. The discussion revealed: (i) assessment instruments; (ii) assessor factors; and (iii) the subjectivity of judgement as the major factors influencing assessment. CONCLUSIONS Assessment moderation is a useful method for improving the quality of assessment decisions by sharing understanding and aligning standards of performance.

Abstract
Abstract
Background: Approximately 70% of newly diagnosed breast cancers express estrogen receptor alpha (ERα), and are treated with agents that block ER signaling. Acquired mutations in ESR1, the gene that encodes ERα, have been associated with resistance to aromatase inhibitor therapy in patients with ER positive metastatic breast cancer (ER+ mBC). The most frequently occurring ESR1 mutations are clustered between amino acids 536 to 538 within the ligand binding domain (LBD), although limited data exists characterizing the full mutation profile in a large number of breast cancer samples.
Methods: We surveyed the Foundation Medicine dataset of 7590 primary and metastatic breast cancer tumor samples for ESR1 short variants and copy number alterations. Hormone receptor status was unavailable, therefore two assumptions were made to provide an estimate of prevalence in the ER+ HER2- population: 70% of the tumor samples are from ER+ HER2- patients, and all ESR1 mutations from non-HER2 amplified metastatic sites are from ER+ HER2- patients. In a separate cohort of 48 ER+ mBC patients, circulating tumor DNA (ctDNA) was analyzed for ESR1 mutations using the BEAMing method by Sysmex and with Foundation Medicine's sequencing assay, FoundationACT (Assay for Circulating Tumor DNA).
Results: The prevalence of mutations in ER+ HER2- breast cancer was estimated to be 22% in samples from metastatic sites but less than 3% in samples from primary sites. ESR1 amplification was rare in samples from both primary and metastatic disease sites at 1.3% and 2.0% respectively. A total of 153 unique short variants of known and unknown status were identified. In addition to hotspot mutations at 537 and 538, previously undescribed rare mutations were identified throughout the entire length of the LBD, although 10 alterations at amino acids 380, 463, 536, 537, and 538 account for 86% of all ESR1 mutations in the ER+ HER2- metastatic sites. We also characterized the overlap of ESR1 alterations with commonly altered and clinically relevant genes in breast cancer, including PIK3CA mutations and HER2 amplification, and we report here a landscape of co-occurring alterations. In the cohort of patient samples where ctDNA was analyzed, BEAMing and FoundationAct assays both detected ESR1 mutations in 19 out of 48 samples, and overall concordance of mutation status (wild-type vs mutant) was 100%. A total of 51 individual mutations were detected with the BEAMing assay, 42 of which were detected with the FoundationACT assay. Seven mutations that were undetected by FoundationACT had mutant allele frequencies less than 0.1%. Ten ESR1 mutations were detected only by FoundationACT, 9 of which are not covered with the BEAMing assay. Alterations in PIK3CA, CDH1, TP53, ERBB2, and other breast cancer relevant genes were also detected with FoundationACT.
Conclusions: Understanding the mutational landscape of ESR1 and co-occurring alterations is important for diagnostic development in conjunction with the clinical development of novel anti-endocrine therapies. Our data demonstrate a large spectrum of mutations in the LBD in addition to known hotspot mutations. In addition, the FoundationACT assay offers a robust NGS-based method to screen for mutations in ctDNA that is highly concordant with digital PCR methods.

Abstract
Random effects in the repeatability of refractive index and absorption edge position of tantalum pentoxide layers prepared by plasma-ion-assisted electron-beam evaporation, ion beam sputtering, and magnetron sputtering are investigated and quantified. Standard deviations in refractive index between 4*10-4 and 4*10-3 have been obtained. Here, lowest standard deviations in refractive index close to our detection threshold could be achieved by both ion beam sputtering and plasma-ion-assisted deposition. In relation to the corresponding mean values, the standard deviations in band-edge position and refractive index are of similar order.

Abstract
BACKGROUND The house dust mite (HDM) allergen Der p 13 could be a lipid-binding protein able to activate key innate signaling pathways in the initiation of the allergic response. We investigated the IgE reactivity of recombinant Der p 13 (rDer p 13), its lipid-binding activities, and its capacity to stimulate airway epithelium cells. METHODS Purified rDer p 13 was characterized by mass spectrometry, circular dichroism, fluorescence-based lipid-binding assays, and in silico structural prediction. IgE-binding activity and allergenic potential of Der p 13 were examined by ELISA, basophil degranulation assays, and in vitro airway epithelial cell activation assays. RESULTS Protein modeling and biophysical analysis indicated that Der p 13 adopts a β-barrel structure with a predominately apolar pocket representing a potential binding site for hydrophobic ligands. Fluorescent lipid-binding assays confirmed that the protein is highly selective for ligands and that it binds a fatty acid with a dissociation constant typical of lipid transporter proteins. The low IgE-binding frequency (7%, n = 224) in Thai HDM-allergic patients as well as the limited propensity to activate basophil degranulation classifies Der p 13 as a minor HDM allergen. Nevertheless, the protein with its presumptively associated lipid(s) triggered the production of IL-8 and GM-CSF in respiratory epithelial cells through a TLR2-, MyD88-, NF-kB-, and MAPK-dependent signaling pathway. CONCLUSIONS Although a minor allergen, Der p 13 may, through its lipid-binding capacity, play a role in the initiation of the HDM-allergic response through TLR2 activation.

Abstract
Abstract
Background: Standard treatment options for patients with metastatic triple negative breast cancer (TNBC) are limited to chemotherapy. Molecular profiling of tumors may allow for novel treatment recommendations.
Methods: We initiated a prospective study designated IMAGE. Women with newly progressing metastatic TNBC who received at least one line of prior chemotherapy were eligible. New metastatic biopsies were obtained for molecular profiling at study entry. Archived metastatic biopsy specimens were allowed if patients had not commenced new systemic therapy. The specimens were reviewed by the study pathologist and stained for ER, PR, HER2, and androgen receptor (AR) by immunohistochemistry. Specimens underwent hybrid-capture based comprehensive genomic profiling (CGP) (Foundation Medicine Inc., Cambridge, MA). Clinical data and genomic profiling reports were reviewed by the GAITWAY (Genomic Alterations in Tumors with Actionable Yields) Molecular Profile Tumor Board. Recommendations were communicated to the treating oncologist and patients were followed for treatment decision and clinical outcomes. Peripheral blood was also analyzed by an investigational assay for circulating plasma tumor DNA (ptDNA) (Foundation Medicine Inc.) at study entry, and when obtainable, from serial blood draws at time of progression. The primary objective was to assess feasibility of completing the process from consent to GAITWAY recommendations within 28 days for at least 80% of patients.
Results: From September 2013 to April 2015, we enrolled 26 eligible women. Median age was 55 (range 25-67); patients identified as white 12 (46%), black 11 (42%), or other 3 (12%); median number of prior lines of treatment was 3; and 65.4% of patients had visceral disease. Twenty (77%) eligible patients received CGP of a metastatic site biopsy. Six patients did not undergo CGP due to either absence of a metastatic site amenable for biopsy or inadequate tissue for CGP. The study met the predefined statistical endpoint for futility and was closed after 20 patients had undergone CGP. Twelve (60%) evaluable patients received treatment recommendations within 28 days of study consent. Failure to meet this time frame was due to difficulties in accessing archival tumor tissue (N=5) and need for additional tissue for molecular analysis (N=3). Preliminary results demonstrate high concordance between mutations in metastatic biopsies and ptDNA in 15/17 patients.
Enrolled in IMAGE26Successful NGS20Potentially actionable mutation identified15GAITWAY recommended targeted therapy as possible next treatment13Received targeted therapy4
Conclusions: CGP of patients with metastatic TNBC can provide additional information that may help direct treatment. However, difficulties in obtaining adequate tumor tissue may hinder this approach. Use of a well-validated ptDNA profiling assay could be an alternative to overcome these limitations.

Abstract
BACKGROUND The medial sural artery perforator (MSAP) flap is a fasciocutaneous flap that is gaining popularity for intra-oral reconstructions. The aim of this two-centre review was to evaluate the use of the MSAP flap in intra-oral reconstructions and report our experiences. METHODS Data were collected prospectively on 35 consecutive intra-oral reconstructions using the free MSAP flap. Patient details and intraoperative flap details were recorded. RESULTS Thirty-five patients underwent intra-oral reconstruction with a free MSAP flap (26 males and nine females). The average flap dimensions were a length of 8.03 cm, a width of 5.0 cm and a thickness of 7.1 mm. Twenty-two flaps had two perforators, and the average pedicle length was 11.1 cm. There were no flap losses. Ninety-one per cent of donor sites were closed primarily. There were two minor complications related to donor-site wound dehiscence, which required delayed skin grafting. The overall complication rate was 5.7%. CONCLUSIONS The MSAP flap is a good choice for intra-oral reconstruction. It has reliable anatomy and provides thin, pliable skin with a long pedicle. In addition, donor morbidity is low as the donor site can be closed directly in most cases. It is currently our flap of choice for small intra-oral soft tissue defects.
