Abstract
CIViC (Clinical Interpretation of Variants in Cancer; civicdb.org) is a crowd-sourced, public domain knowledgebase composed of literature-derived evidence characterizing the clinical utility of cancer variants. As clinical sequencing becomes more prevalent in cancer management, the need for cancer variant interpretation has grown beyond the capability of any single institution. CIViC contains peer-reviewed, published literature curated and expertly-moderated into structured data units (Evidence Items) that can be accessed globally and in real time, reducing barriers to clinical variant knowledge sharing. We have extended CIViC's functionality to support emergent variant interpretation guidelines, increase interoperability with other variant resources, and promote widespread dissemination of structured curated data. To support the full breadth of variant interpretation from basic to translational, including integration of somatic and germline variant knowledge and inference of drug response, we have enabled curation of three new Evidence Types (Predisposing, Oncogenic and Functional). The growing CIViC knowledgebase has over 300 contributors and distributes clinically-relevant cancer variant data currently representing >3200 variants in >470 genes from >3100 publications.

Abstract
MOTIVATION Environmental DNA (eDNA), as a rapidly expanding research field, stands to benefit from shared resources including sampling protocols, study designs, discovered sequences, and taxonomic assignments to sequences. High-quality community shareable eDNA resources rely heavily on comprehensive metadata documentation that captures the complex workflows covering field sampling, molecular biology lab work, and bioinformatic analyses. There are limited sources that provide documentation of database development on comprehensive metadata for eDNA and these workflows and no open-source software. RESULTS We present medna-metadata, an open-source, modular system that aligns with Findable, Accessible, Interoperable, and Reusable guiding principles that support scholarly data reuse and the database and application development of a standardized metadata collection structure that encapsulates critical aspects of field data collection, wet lab processing, and bioinformatic analysis. Medna-metadata is showcased with metabarcoding data from the Gulf of Maine (Polinski et al., 2019). AVAILABILITY AND IMPLEMENTATION The source code of the medna-metadata web application is hosted on GitHub (https://github.com/Maine-eDNA/medna-metadata). Medna-metadata is a docker-compose installable package. Documentation can be found at https://medna-metadata.readthedocs.io/en/latest/?badge=latest. The application is implemented in Python, PostgreSQL and PostGIS, RabbitMQ, and NGINX, with all major browsers supported. A demo can be found at https://demo.metadata.maine-edna.org/. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Abstract
BACKGROUND Immunoglobulin G (IgG) subclass 2 deficiency is the most frequent IgG subclass deficiency identified in patients with bronchiectasis, but its clinical significance is not known. AIM To analyse if bronchiectasis patients with isolated IgG2 deficiency at risk of recurrent exacerbations and/or hospitalization? Do patients with IgG2 deficiency have worse disease progression? DESIGN AND METHODS This is a retrospective study (2015-20) exploring independent risk factors for recurrent exacerbations (3 or more per year) and/or hospitalization with bronchiectasis exacerbations using multivariable models using binary logistic regression. There was no patient with IgG deficiency, IgG 1, 3 or 4 deficiency, or IgA or IgM deficiency included. In this model, the authors included: serum IgG2 level; lung function; body mass index; MRC breathlessness scale; age; sex; number of bronchiectatic lobes; bacterial colonization; comorbidities; and the use of long-term immunosuppressant drugs or antibiotics for more than 28 days. Analysing 2-year longitudinal data, one-way ANOVA and Mann-Whitney U-test were used to compare bronchiectasis severity between patients with different IgG2 levels. RESULTS Serum IgG2 levels (<2.68 g/l, 2.68-3.53 g/l and 3.54-4.45 g/l); hospital admission in the preceding 2 years; bacterial colonization with potentially pathogenic organisms and asthma were independent predictors for three or more bronchiectasis exacerbations. Those with low IgG2 levels (<2.68 g/l and 2.68-3.53 g/l), had worsening progression of their bronchiectasis, using the Bronchiectasis Severity Index, over 1 year compared with those who were IgG2 replete (>4.45 g/l) (P = 0.003, 0.013). CONCLUSION Reduced IgG2 levels were an independent predictor for bronchiectasis exacerbations and have increased disease progression.

Abstract
INTRODUCTION Lung cancer is the leading cause of cancer-related death. Delays may have an impact on patient survival. The objective of this study was to evaluate the diagnostic and therapeutic management times for patients admitted for lung cancer treatment in the Respiratory Department of CHU de Caen Normandie. MATERIALS AND METHODS This is a retrospective, single-center and observational study, conducted on all patients treated for lung cancer from June 2017 to January 2018 in our department of pneumology in the Caen Normandie CHU. The main median times were investigated were: Global Time (abnormal imaging-treatment), Diagnosis time (abnormal imaging-diagnosis) and Treatment Time (diagnosis-treatment). RESULTS One hundred and twenty-seven (127) patients were included. Median global time was 55.5 days [31,25; 393], median diagnosis time was 22 days [13; 49], and median treatment time was 24.5 days [12,25; 45]. DISCUSSION Our treatment times are consistent with those previously published. Areas for improvement are being developed in accordance with the 2014-2019 cancer plan, in particularly the creation in our institution of a specific care pathway for patients with lung cancer.

Abstract
AIM To describe person-reported outcomes of the Basal-IQ predictive low-glucose-suspend system (Tandem Diabetes Care, San Diego, CA, USA) in real-world use. METHODS Adults with type 1 diabetes/caregivers of minors with type 1 diabetes completed the Diabetes Impact and Device Satisfaction questionnaire (11 items scored on 10-point Likert scales) prior to Basal-IQ system initiation, and at 2, 4 and 6 months post-initiation. Analysis was stratified by previous insulin treatment method. Beta mixed models were used to measure change in device satisfaction (e.g. trust, ease of use) and diabetes impact (e.g. hypoglycaemia fear, poor sleep) scores between time points, adjusting for baseline covariates. RESULTS A total of 967 adults and caregivers [54% women, mean (sd) age 36 (17) years, 57% Tandem pump users, 27% non-Tandem pump users, 17% multiple daily injection users] completed surveys. Device satisfaction significantly increased from baseline to 2 months in all groups (P<0.001 multiple daily injection and non-Tandem pump users; P=0.048 Tandem pump users), and was sustained from 2 to 6 months in all groups. Diabetes impact decreased significantly from baseline to 2 months in all groups (P<0.001 for all), was sustained from 2 to 6 months in multiple daily injection and Tandem pump users, and increased slightly at 4 months/decreased at 6 months in non-Tandem users. CONCLUSION The Basal-IQ system increased device satisfaction and reduced diabetes impact in all users in the first 2 months of use, and satisfaction was sustained over 6 months, with small fluctuations.

Abstract
Progenitors in the dorsal lateral ganglionic eminence (dLGE) are known to give rise to olfactory bulb (OB) interneurons and intercalated cells (ITCs) of the amygdala. The dLGE enriched transcription factor Sp8 is required for the normal generation of ITCs as well as OB interneurons, particularly the calretinin (CR)-expressing subtype. In this study, we used a genetic gain-of-function approach in mice to examine the roles Sp8 plays in controlling the development of dLGE-derived neuronal subtypes. Misexpression of Sp8 throughout the ventral telencephalic subventricular zone (SVZ) from early embryonic stages, led to an increased generation of ITCs which was dependent on Tshz1 gene dosage. Additionally, Sp8 misexpression impaired rostral migration of OB interneurons with clusters of CR interneurons seen in the SVZ along with decreased differentiation of calbindin OB interneurons. Sp8 misexpression throughout the ventral telencephalon also reduced ventral LGE neuronal subtypes including striatal projection neurons. Delaying Sp8 misexpression until E14-15 rescued the striatal and amygdala phenotypes but only partially rescued OB interneuron reductions, consistent with an early window of striatal and amygdala neurogenesis and ongoing OB interneuron generation at this late stage. Our results demonstrate critical roles for the timing and neuronal cell-type specificity of Sp8 expression in mouse LGE neurogenesis.

Abstract
Background Saksenaea species (spp.) are uncommon causes of mucormycosis but are emerging pathogens mostly associated with trauma and soil contamination often in immunocompetent hosts. Due to lack of sporulation in the laboratory, diagnosis and susceptibility testing is difficult so optimal treatment regimens are unknown. Case presentation A 67 year-old man from the Northern Territory in Australia, with a history of eosinophilic granulomatosis with polyangiitis, developed disseminated Saksenaea infection after initially presenting with symptoms consistent with bacterial pyelonephritis. Despite a delay in diagnosis; with aggressive surgical management and dual therapy with amphotericin B and posaconazole, he survived. Conclusions We describe an unusual case of disseminated infection with a favourable outcome to date.

Abstract
Mycotoxins produced by Fusarium species including trichothecenes, zearalenone and fumonisins, can co-contaminate food and feed throughout the supply chain, including cereal grains and animal feeds. There is an increasing demand to enhance global food security by improving the monitoring of mycotoxins throughout our food supply chain. For time and cost-efficient analysis, rapid tests capable of detecting multiple toxins from a single sample are ideal. Considering these current trends in mycotoxin testing, this project examined the feasibility of using both a portable and non-portable mass-based biosensor for multiplex mycotoxin detection. The biosensor was a mass sensitive microarray (MSMA) which consisted of 4 × 16 miniaturized mass sensitive transducer pixels based on solidly mounted resonator (SMR) technology. Functionalisation of individual pixels on the sensor surface using nano-spotting technology for the simultaneous and semi-quantitative detection of three regulated mycotoxins: T2-toxin (T2) zearalenone (ZEN), and fumonisin B1 (FumB1) was examined. With the integration of portable and non-portable microfluidic devices for antibody and standard sample injections, competitive inhibition assays were developed followed by singleplex and multiplex calibration curves. The characteristics and performance of the MSMA were evaluated including sensitivity which was determined as the concentration causing 50% inhibition. Sensitivity of singleplex assays using the portable microfluidic device (PMD) were 1.3 ng/ml, 2.0 ng/ml and 6.8 ng/ml for T2, FumB1 and ZEN, respectively. Sensitivity of the multiplex assay again using the PMD was 6.1 ng/ml, 3.6 ng/ml and 2.4 ng/ml for T2, FumB1 and ZEN, respectively. The PMD was an easy to use and highly sensitive screening tool which has been demonstrated for the multiplex detection of three regulated mycotoxins. Analysis was in real time and results were fully digital. Since detection of analytes was by mass it was both a label-free and cost-efficient method proposed method of analysis for mycotoxins.

Abstract
BACKGROUND Skin tears are acute wounds that are frequently misdiagnosed and under-reported. A standardized and globally adopted skin tear classification system with supporting evidence for diagnostic validity and reliability is required to allow assessment and reporting in a consistent way. OBJECTIVES To measure the validity and reliability of the International Skin Tear Advisory Panel (ISTAP) Classification System internationally. METHODS A multicountry study was set up to validate the content of the ISTAP Classification System through expert consultation in a two-round Delphi procedure involving 17 experts from 11 countries. An online survey including 24 skin tear photographs was conducted in a convenience sample of 1601 healthcare professionals from 44 countries to measure diagnostic accuracy, agreement, inter-rater reliability and intrarater reliability of the instrument. RESULTS A definition for the concept of a 'skin flap' in the area of skin tears was developed and added to the initial ISTAP Classification System consisting of three skin tear types. The overall agreement with the reference standard was 0·79 [95% confidence interval (CI) 0·79-0·80] and sensitivity ranged from 0·74 (95% CI 0·73-0·75) to 0·88 (95% CI 0·87-0·88). The inter-rater reliability was 0·57 (95% CI 0·57-0·57). The Cohen's Kappa measuring intrarater reliability was 0·74 (95% CI 0·73-0·75). CONCLUSIONS The ISTAP Classification System is supported by evidence for validity and reliability. The ISTAP Classification System should be used for systematic assessment and reporting of skin tears in clinical practice and research globally. What's already known about this topic? Skin tears are common acute wounds that are misdiagnosed and under-reported too often. A skin tear classification system is needed to standardize documentation and description for clinical practice, audit and research. What does this study add? The International Skin Tear Advisory Panel Classification System was psychometrically tested in 1601 healthcare professionals from 44 countries. Diagnostic accuracy was high when differentiating between type 1, 2 and 3 skin tears using a set of validated photographs.

Abstract
AIMS Differences in the bacterial population of cucumber fermentations brined with no salt, 100 mmol l-1 (1·1%) calcium chloride (CaCl2 ) or 1·03 mol l-1 (6%) sodium chloride (NaCl) were studied. METHODS AND RESULTS Changes in the microbiology and chemistry of commercial and laboratory scale cucumber fermentations occurring as a function of time were monitored using colony counts and metagenetic analysis, and a pH probe and high-performance liquid chromatography analysis respectively. Dissolved oxygen and carbon dioxide content were monitored in commercial fermentations. Fermentations brined with calcium chloride (CaCl2 ) or no salt sustained faster microbial growth and reduction in pH than those brined with 1·03 mol l-1 NaCl. Leuconostoc, Lactococcus and Weissella dominated in fermentations brined with no salt or 100 mmol l-1 CaCl2 on day 1 as compared to Weissella and enterobacteria in fermentations containing 1·03 mol l-1 NaCl. Lactobacilli dominated all fermentations by the third day, regardless of salt type, and was followed, in relative abundance by Pediococcus, Leuconostoc, Lactococcus and Weissella. From 84 to 96% of the population was composed of Lactobacillus by day 7 of the fermentations, except in the no salt fermentations in which a mixed population of LAB remained. The population of LAB found in commercial cucumber fermentations brined with 100 mmol l-1 CaCl2 (n = 18) or 1·03 mol l-1 NaCl (n = 9) mimicked that of laboratory fermentations. A declining population of aerobes was detected in commercial fermentations brined with CaCl2 on day 1. CONCLUSION A reduced NaCl content in cucumber fermentation enhances microbial diversity. SIGNIFICANCE AND IMPACT OF THE STUDY This study fills a knowledge gap and aids in the design of improved reduced NaCl cucumber fermentations.

Abstract
Abstract
Rationale & Objective: Granulocyte colony-stimulating factors (G-CSFs) are utilized to decrease the incidence of febrile neutropenia (FN) in patients with cancers undergoing chemotherapy treatments. In 2015 biosimilar filgrastim-sndz was the first biosimilar to be approved and launched in the US market. Limited data exists in ascertaining the impact of biosimilars on patient out-of-pocket (OOP) expenditures. The objective of this simulation model was to estimate potential OOP cost savings through use of filgrastim-sndz over reference filgrastim from a Medicare breast cancer patient perspective.
Methods: An Excel simulation analysis was conducted among breast cancer patients treated with biosimilar filgrastim-sndz or the branded reference filgrastim (identified through HCPCS codes). Data from the 2016 Medicare Limited Data Set (5% sample of the carrier file) was used to populate the model. The payment calculation worksheet within the Medicare carrier file was used to calculate the average Medicare payment to the provider and the average beneficiary OOP responsibility per claim of either filgrastim-sndz or reference filgrastim. The average OOP reduction per claim for a filgrastim-sndz beneficiary relative to a reference filgrastim beneficiary was multiplied to a hypothetical FN prevalent population of 100,000 beneficiaries (average of 10 claims per beneficiary) to estimate the potential OOP savings.
Results: Data for 616 filgrastim-sndz and 1,064 reference filgrastim claims were used to populate the model. The average Medicare allowed charge amount per claim for a filgrastim-sndz beneficiary was $362.8 versus $406.9 for a reference filgrastim beneficiary, while corresponding average Medicare payments to the provider were $284.1 and $316.9, respectively. On an average, OOP responsibility for a filgrastim-sndz beneficiary was lower compared to a reference filgrastim beneficiary ($72.9 versus $82.5) leading to a cost saving per claim of $9.60. When extrapolated to 100,000 beneficiaries (1,000,000 claims), the overall cost saving was projected to be around $9.6 million.
Conclusions: Our simulation model estimated a potential OOP Medicare breast cancer beneficiary saving of around $9.6 million, based on a hypothetical population of 100,000 FN beneficiaries, with the use of biosimilar filgrastim-sndz over reference filgrastim. Further real-world analyses are required to evaluate the true cost saving potential from a breast cancer patient perspective with the use of biosimilars over reference biologics.

Abstract
Detailed knowledge regarding sensor based technologies for the detection of food contamination often remains concealed within scientific journals or divided between numerous commercial kits which prevents optimal connectivity between companies and end-users. To overcome this barrier The End user Sensor Tree (TEST) has been developed. TEST is a comprehensive, interactive platform including over 900 sensor based methods, retrieved from the scientific literature and commercial market, for aquatic-toxins, mycotoxins, pesticides and microorganism detection. Key analytical parameters are recorded in excel files while a novel classification system is used which provides, tailor-made, experts' feedback using an online decision tree and database introduced here. Additionally, a critical comparison of reviewed sensors is presented alongside a global perspective on research pioneers and commercially available products. The lack of commercial uptake of the academically popular electrochemical and nanomaterial based sensors, as well as multiplexing platforms became very apparent and reasons for this anomaly are discussed.

Abstract
OBJECTIVE To evaluate the available evidence on probiotic use in older adults from human studies. DESIGN systematic review. METHODS The databases Embase, CINAHL and Medline were searched in December of 2017 for studies in humans where probiotics were used to modify a health outcome in older people. The quality of studies was evaluated using the Critical Appraisal Skills Program (CASP) assessment tool and the Cochrane Risk of Bias Assessment tool. PARTICIPANTS Subjects aged over sixty years either through specified selection criteria or where the mean participant age was greater than sixty. INTERVENTIONS Probiotic supplements. MEASUREMENTS Pre-specified clinically measurable health outcomes in age related conditions. RESULTS 1210 articles were identified. After quality assessment and selection criteria were applied, 33 articles were identified to be included for review. As these studies cover a variety of applications and used customised protocols accordingly, meta-analysis was not possible and synthesis is in narrative form. CONCLUSIONS A growing body of research has applied commercially available probiotic preparations across care settings for age related conditions including gut dysmotility, osteoporosis, common infectious diseases and cognitive impairment. Although methodologies vary, randomised controlled trials have reproduced results in these areas, and so warrant consideration of probiotics as a low risk adjuvant treatment for specific indications in the elderly.

Abstract
BACKGROUND The optimal way of pacing in patients with an indication for pacing and concomitant first-degree atrioventricular (AV)-block is not known, and consequently, firm guidelines on this topic are lacking. This study explored the current pacemaker programming pattern in patients with first-degree AV-block who have a dual chamber pacemaker without cardiac resynchronization. METHODS The study was a retrospective chart review conducted at Duke University Hospital. Patients receiving a pacemaker due to sinus node dysfunction with coexistent first-degree AV-block were studied. Baseline demographics and characteristics, as well as pacemaker programming parameters and follow-up data, were collected through chart review. Preimplantation and postimplantation electrocardiograms were analyzed. RESULTS A total of 74 patients were included (mean age, 75 ± 11 y; 53% men). The mean ± SD preimplant PR interval and QRS duration was 243 ± 46 and 110 ± 30 milliseconds, respectively. A history of atrial fibrillation was present in 49% of the patients, and 77% had a normal left ventricular ejection fraction. The majority of patients (65%) had their pacemakers programmed to atrial pacing (AAI/DDD +/-R), whereas 32% and 2.7% of the pacemakers were programmed to AV-sequential pacing (DDD) and ventricular pacing (VVI), respectively. There were no significant differences in baseline characteristics or electrocardiogram measures between patients programmed to the 3 pacing modes. Patients with pacemakers programmed to AAI had a lower ventricular pacing percentage at follow-up (8 vs 55, and 46% [DDD and VVI, respectively]; P < .001). CONCLUSIONS There was no evident association between baseline characteristics and programmed pacing mode in patients with first-degree AV-block. The choice of pacing mode affects long-term pacing burden, which in turn has been shown to influence outcome.

Abstract
Abstract
RATIONALE & OBJECTIVES: Biosimilar filgrastim may offer significant cost advantages over originator filgrastim and pegfilgrastim. The objectives were (1) to evaluate for the US the comparative cost-minimization of chemotherapy-induced (febrile) neutropenia (CIN/FN) prophylaxis with biosimilar filgrastim ZARZIO® over originator filgrastim NEUPOGEN®, and originator pegfilgrastim NEULASTA® and NEULASTA/ONPRO® injection device with the health-care provider (HP) providing full administration, using 3Q2016 average selling price (ASP); and (2) to apply the different savings estimates to a breast cancer case study.
METHODS: Cost-minimization analysis of [1] acquisition costs for one patient for one chemotherapy cycle for 1 to 14 days (d) using per unit dose, and [2] administration costs using Current Procedural Terminology (CPT) codes. We calculated [1] the general cost of prophylaxis for one cycle with each agent, with standard filgrastim administrations ranging from 1-14 days and pegfilgrastim limited to single administration; and [2] the cost-savings that could be accrued from 1-14d prophylaxis with ZARXIO® over the three originator options. The case study concerns a 43 y/o Caucasian female, newly diagnosed with stage 2 HER2-negative breast cancer being started on TAC (FN risk >20%); unremarkable medical history; no comorbidities; with primary prophylaxis initiated in cycle 1 and continued through 6 cycles per local protocol (single NEULASTA® or NEULASTA/ONPRO® or 11d NEUPOGEN® or ZARXIO®).
RESULTS: Using ASP+CPT, prophylaxis cost per dose (rounded) was $260 for ZARXIO®, $326 for NEUPOGEN®, $3,926 for NEULASTA®; $3,910 for NEULASTA®. In general, cost-savings per cycle from ZARXIO® over NEUPOGEN® ranged from $65 (1d) to $916 (14d); over Neulasta®, from $3,666 (1d) to $284 (14d); and over NEULASTA/ONPRO®, from $3,649 (1d) to $267 (14d). In the breast cancer case study, cost of prophylaxis per one cycle was $2,862 for ZARXIO® (11d), $3,582 for NEUPOGEN® (11d) vs. $3926 for NEULASTA® and $3910 for NEULASTA/ONPRO® single-injection. Cost-savings per cycle from ZARXIO® use were $719 vs. NEUPOGEN®, $1,064 vs. NEULASTA®, and $1,047 vs. NEULASTA/ONPRO®. Total savings from ZARXIO® use over all 6 TAC cycles were $4,316 vs. NEUPOGEN®, $6,385 vs. NEULASTA®, and $6,284 vs. NEULASTA/ONPRO®.
CONCLUSIONS: In general, CIN/FN prophylaxis with ZARXIO® for 1-14d generates significant cost savings over NEUPOGEN®, NEULASTA® and NEULASTA/ONPRO generating significant cost-savings. In the case study of the 43 y/o HER-negative breast cancer patient treated with TAC and prescribed 6 cycles of primary prophylaxis with 11d standard or single-administration pegfilgrastim, savings reached as high as $6,385 for the full course of chemotherapy. Given the trial evidence of non-inferiority of pegfilgrastim over filgrastim, the clinical trend for <14d of filgrastim prophylaxis, and payer trends to authorize filgrastim vs. pegfilgrastim prophylaxis, using biosimilar Zarxio® is rational from both a economic perspective; as illustrated also in the breast cancer case study.

Abstract
Recent studies have shown that the LIM-homeodomain transcription factor Isl1 is required for the survival and differentiation of direct pathway striatonigral neurons during embryonic development. The downstream effectors of Isl1 in these processes are presently unknown. We show here that Foxo1, a transcription factor that has been implicated in cell survival, is expressed in striatal projection neurons (SPNs) that derive from the Isl1 lineage (i.e. direct pathway SPNs). Moreover, Isl1 conditional knockouts (cKOs) show a severe loss of Foxo1 expression at E15.5 with a modest recovery by E18.5. Although Foxo1 is enriched in the direct pathway SPNs at embryonic stages, it is expressed in both direct and indirect pathway SPNs at postnatal time points as evidenced by co-localization with EGFP in both Drd1-EGFP and Drd2-EGFP BAC transgenic mice. Foxo1 was not detected in striatal interneurons as marked by the transcription factor Nkx2.1. Conditional knockout of Foxo1 using Dlx5/6-CIE mice results in reduced expression of the SPN marker Darpp-32, as well as in the direct pathway SPN markers Ebf1 and Zfp521 within the embryonic striatum at E15.5. However, this phenotype improves in the conditional mutants by E18.5. Interestingly, the Foxo family members, Foxo3 and Foxo6, remain expressed at late embryonic stages in the Foxo1 cKOs unlike the Isl1 cKOs where Foxo1/3/6 as well as the Foxo1/3 target Bach2 are all reduced. Taken together, these findings suggest that Foxo-regulated pathways are downstream of Isl1 in the survival and/or differentiation of direct pathway SPNs.

Abstract
Cutaneous myiasis is a well-described problem in travellers to endemic regions including military personnel. Realistic training is important to ensure that healthcare workers have the confidence and expertise to recognise cutaneous myiasis and safely remove larvae if required. A model is described here that is simple, reproducible and realistic, and will allow for training of military healthcare workers in safe surgical removal of larvae when required.

Abstract
Objective: To study the clinical profile of Klippel–Trenaunay syndrome (KTS) and the management of venous malformations (VMs) with ultrasound-guided foam sclerotherapy using the compass technique. Methods: In this open prospective series, 11 consecutive patients with KTS seeking therapy at a phlebology group practice were included. Seven (64%) of them were post-surgical recurrences. Results: Pain was the commonest presenting complaint (100%), accompanied with VMs/ varicose veins in all except one (91%). Chronic venous insufficiency (CVI) was seen in seven (64%). Soft tissue and bone deformity was present in all (100%). Limb lengthening was frequent and detected in eight (73%), thickening in six (54%); unusually, one patient (9%) presented with severe thinning and shortening of the leg. Venous malformation was the primary vascular problem in nine patients (82%), with capillary malformation (CM)/port wine stain in seven (64%) and isolated lymphatic malformation (LM) in two (18%). The lateral embryonic/Klippel–Trenaunay (KT) vein was detected in 10 patients (91%). Deep vein deformity was not detected in any of them. All the deformities were of the lower limb (100%), while two (18%) had deformities of the thorax and one (9%) had gastrointestinal (GI) malformation. None of the patients gave family history of KTS, while five (45%) had history of varicosities in the family. Eight patients (73%) completed the therapeutic plan with a mean follow-up of 5±3.9 years. An excellent to good type result could be documented in six of the eight cases (75%). These patients had an event-free, good quality of life. Follow-up duplex studies revealed the evolving refluxing tracts requiring sequential therapies. Conclusions: The results in this series demonstrate the utility of foam sclerotherapy using the compass technique in the management of KTS. Chronicity of the VMs in KTS necessitates strict clinical monitoring and sequential therapies.

Abstract
Research in biosensing approaches as alternative techniques for food diagnostics for the detection of chemical contaminants and foodborne pathogens has increased over the last twenty years. The key component of such tests is the biorecognition element whereby polyclonal or monoclonal antibodies still dominate the market. Traditionally the screening of sera or cell culture media for the selection of polyclonal or monoclonal candidate antibodies respectively has been performed by enzyme immunoassays. For niche toxin compounds, enzyme immunoassays can be expensive and/or prohibitive methodologies for antibody production due to limitations in toxin supply for conjugate production. Automated, self-regenerating, chip-based biosensors proven in food diagnostics may be utilised as rapid screening tools for antibody candidate selection. This work describes the use of both single channel and multi-channel surface plasmon resonance (SPR) biosensors for the selection and characterisation of antibodies, and their evaluation in shellfish tissue as standard techniques for the detection of domoic acid, as a model toxin compound. The key advantages in the use of these biosensor techniques for screening hybridomas in monoclonal antibody production were the real time observation of molecular interaction and rapid turnaround time in analysis compared to enzyme immunoassays. The multichannel prototype instrument was superior with 96 analyses completed in 2h compared to 12h for the single channel and over 24h for the ELISA immunoassay. Antibodies of high sensitivity, IC50's ranging from 4.8 to 6.9ng/mL for monoclonal and 2.3-6.0ng/mL for polyclonal, for the detection of domoic acid in a 1min analysis time were selected. Although there is a progression for biosensor technology towards low cost, multiplexed portable diagnostics for the food industry, there remains a place for laboratory-based SPR instrumentation for antibody development for food diagnostics as shown herein.
