IgA vasculitis

description: Background: Nephritis is a recognised complication in children with IgA Vasculitis (IgAV, previously Henoch-Schönlein Purpura) and accounts for 1-2% of kidney failure. Understanding the pathophysiology of this disease may allow identification of targets for earlier diagnosis and/or treatment. The aim of this cross-sectional study was to assess whether Immunoglobulin A (IgA) and Complement 5a (C5a) could be detected in the urine of children with IgAV and whether they are increased in patients with nephritis. Methods: Paediatric patients and healthy controls (HC) were recruited as part of the IgA Vasculitis Study (Alder Hey Children’s NHS Foundation Trust, Liverpool, REC 17/NE/0390). Urinary IgA and C5a levels were measured using commercially available ELISA kits (Novus Biological) and normalised to creatinine. Patients were grouped into IgAV nephritis (IgAVN) or IgAV with no nephritis (IgAVwoN). Nephritis was defined as a urinary albumin-creatinine ratio (UACR) > 30 mg/mmol at the time of sample collection. Statistical analysis was performed using GraphPad Prism version 8.0. Data is presented as median [range]. Results: A total of 59 children were included in this study (IgAVN n=11, IgAVwoN n=36, HC n=12). Median age was 7.1 years [1.8-17.9] and male to female ratio was 1.9:1. Urinary IgA and urinary C5a levels were both increased in patients with IgAVN (IgA/Cr –2504.5 ug/g [483.0-12437.7]; C5a/Cr – 720.2 ng/g [157.6-7826.3]) compared to IgAVwoN (IgA/Cr – 535.7 ug/g [4.4-8035.5]; C5a/Cr – 121.5 ng/g [9.03-2214.8]; p < 0.01) and HC (IgA/Cr – 430.6 ug/g [166.4-1168.6]; C5a/Cr – 55.1 ng/g [15.2-1138.9]: p < 0.01). There was no difference between HC and IgAVwoN. There were clear outliers with extremely increased urinary IgA and C5a levels in both IgAVN and IgAVwoN groups (Figure 1). Conclusion: Urinary IgA and C5a can be measured and the concentration appeared to be associated with nephritis in this cohort. These could be useful markers to identify patients who warrant further intervention and/or potential drug targets. Further longitudinal studies are needed to assess their clinical relevance. Disclosures: None.

description: Sequence stratigraphic and Wheeler diagram interpretations require a strong combination of conceptual understanding and diagram reasoning skills. Students are generally exposed to the foundational concepts within sequence stratigraphy (relative sea level, eustasy, base level, and accommodation) in a variety of courses along their degree path, however, one prior study found that few students have a clear scientific conceptual understanding. This study serves two purposes: First, we explore the impact of Wheeler diagram instruction on student learning. Second, we assess students’ common errors on an interpretation task prior to and after Wheeler diagram interpretation. Student conceptual errors are grouped into four categories (fundamental concepts, subaerial erosional unconformities, correlative conformities and sequence identification). In general, student errors were consistent before and after Wheeler diagram instruction. The most common errors related to students identifying the contact between two facies as a stratigraphic or sedimentological feature rather than sedimentary units. Additionally, we provide a set of suggestions for teaching sequence stratigraphy that may help target the common errors and increase student interpretation skill.

IgA vasculitis

description: Background: Vasculitis is a significant cause of end stage renal disease (ESRD) and is not limited to a particular demographic. Renal transplantation is the optimal form of renal replacement therapy (RRT) for suitable patients, and therefore the most appropriate treatment in many with vasculitis. The particular transplant issues related to vasculitis are (i) risk of recurrent disease and (ii) cumulative impact of immunosuppression (typically with pre-transplant burden to manage original disease). We assessed the long-term graft and patient outcomes in vasculitis patients following renal transplantation in Northern Ireland (NI). Methods: Transplant patients with a primary renal disease of vasculitis, (including polyarteritis nodosa, granulomatosis with polyangiitis and ANCA-associated vasculitis), were identified using the NI Kidney Transplant database. Additional information was collected using the NI Electronic Care Record (NIECR) and regional renal-specific electronic system (eMED). Patients from 1978 to 2009 were identified and included for further analysis. Results: There were 24 transplants in 22 patients from 1978 to 2009, two patients were transplanted twice in this period. Table 1 summarises relevant patient and donor information. All kidneys were gifted from brainstem death donors. One case was excluded from further analysis due to immediate technical failure. Median graft survival was 99 months (range 1 to 238 months), with three grafts still functioning. Graft survival was 87.0% at 1 year, 78.3% at 5 years and 34.8% at 10 years. There were 17 deaths over the follow up period, 15 patients died with a functioning graft and 2 died following transplant failure. Median survival was 114 months (range 10 to 238 months), with four patients still alive. Recipient survival following first transplant was 95.2% at 1 year, 85.7% at 5 years and 52.4% at 10 years. Deaths were predominantly due to complications of cardiovascular disease (9), malignancy (5) and infection (2). Conclusions: Renal transplantation is appropriate for patients with ESRD due to vasculitis with comparable outcomes to other transplanted patients in this era. Despite this almost half have died within 10 years of transplantation, but without a predominance of malignancy or infection. Disclosures: None. Table 1. Recipient and donor characteristics

description: This paper presents a new class of high order linear ImEx multistep schemes with large regions of unconditional stability. Unconditional stability is a desirable property of a time stepping scheme, as it allows the choice of time step solely based on accuracy considerations. Of particular interest are problems for which both the implicit and explicit parts of the ImEx splitting are stiff. Such splittings can arise, for example, in variable-coefficient problems, or the incompressible Navier-Stokes equations. To characterize the new ImEx schemes, an unconditional stability region is introduced, which plays a role analogous to that of the stability region in conventional multistep methods. Moreover, computable quantities (such as a numerical range) are provided that guarantee an unconditionally stable scheme for a proposed implicit-explicit matrix splitting. The new approach is illustrated with several examples. Coefficients of the new schemes up to fifth order are provided.

Modified gravity (MOG) is applied to the cluster Abell 1689 and the acceleration data is well fitted without assuming dark matter. Newtonian dynamics and Modified Newtonian dynamics (MOND) are shown not to fit the acceleration data, while a dark matter model based on the Navarro-Frenk-White (NFW) mass profile is shown to fit the acceleration data for the radial range $r > 200$ kpc.

description: During the coating of components like rolls the major parameters are easily to control. But this is not sufficient to guarantee and stable a high coating quality. Additionally non-controllable parameters, e.g. nozzle wear, influence the process mainly. For this purpose a new testing method is necessary. On base of the acoustic emission analysis a testing method was developed in order to control the spraying conditions.In this investigation acoustic emission (AE) is applied to analyse the signals generated by the impact of the molten particles on the component surface. The analysis of the signals is carried out in combination with a new classification method. On account of the very high signal number and the following signal overlapping conventional AE-methods can not be applied. For this reason the whole frequency spectrum has to be analysed. The result does not depend on the component geometry. Neural networks can be used for an industrial application of this method.

Three-dimensional Doppler, polarization-gradient, and magneto-optical forces for atoms and molecules with dark states

description: We theoretically investigate the damping and trapping forces in a three-dimensional magneto-optical trap (MOT), by numerically solving the optical Bloch equations. We focus on the case where there are dark states because the atom is driven on a "type-II" system where the angular momentum of the excited state, $F'$, is less than or equal to that of the ground state, $F$. For these systems we find that the force in a three-dimensional light field has very different behaviour to its one dimensional counterpart. This differs from the more commonly used "type-I" systems ($F'=F+1$) where the 1D and 3D behaviours are similar. Unlike type-I systems where, for red-detuned light, both Doppler and sub-Doppler forces damp the atomic motion towards zero velocity, in type-II systems in 3D, the Doppler force and polarization gradient force have opposite signs. As a result, the atom is driven towards a non-zero equilibrium velocity, $v_{0}$, where the two forces cancel. We find that $v_{0}^{2}$ scales linearly with the intensity of the light and is fairly insensitive to the detuning from resonance. We also discover a new magneto-optical force that alters the normal MOT force at low magnetic fields and whose influence is greatest in the type-II systems. We discuss the implications of these findings for the laser cooling and magneto-optical trapping of molecules where type-II transitions are unavoidable in realising closed optical cycling transitions.

description: Microscopic imaging of local magnetic fields provides a window into the organizing principles of complex and technologically relevant condensed matter materials. However, a wide variety of intriguing strongly correlated and topologically nontrivial materials exhibit poorly understood phenomena outside the detection capability of state-of-the-art high-sensitivity, high-resolution scanning probe magnetometers. We introduce a quantum-noise-limited scanning probe magnetometer that can operate from room to cryogenic temperatures with unprecedented DC-field sensitivity and micron-scale resolution. The Scanning Quantum Cryogenic Atom Microscope (SQCRAMscope) employs a magnetically levitated atomic Bose-Einstein condensate (BEC), thereby providing immunity to conductive and blackbody radiative heating. It has a field sensitivity of 1.4 nT per resolution-limited point ($\sim$2 $μ$m), or 6 nT/$\sqrt{\text{Hz}}$ per point at its duty cycle. Compared to point-by-point sensors, the long length of the BEC provides a naturally parallel measurement, allowing one to measure nearly one-hundred points with an effective field sensitivity of 600 pT$/\sqrt{\text{Hz}}$ for each point during the same time as a point-by-point scanner would measure these points sequentially. Moreover, it has a noise floor of 300 pT and provides nearly two orders of magnitude improvement in magnetic flux sensitivity (down to $10^{-6}$ $Φ_0/\sqrt{\text{Hz}}$) over previous atomic probe magnetometers capable of scanning near samples. These capabilities are, for the first time, carefully benchmarked by imaging magnetic fields arising from microfabricated wire patterns, in a system where samples may be scanned, cryogenically cooled, and easily exchanged. The SQCRAMscope will provide charge transport images at temperatures from room to 4 K in unconventional superconductors and topologically nontrivial materials.

description: Typed lambda categories and Cartesian closed categories are both means of formalizing the process of substitution; we demonstrate that these views are essentially the same; specifically that there is an equivalence between the category of small Cartesian closed categories and the category of typed lambda calculi. First we introduce the basic notions of category, functor, monad, comonad and equivalence of categories; then we use these notions to define the category of small Cartesian closed categories and describe how additional arrows may be adjoined to a Cartesian closed category. Next we provide a definition of a typed lambda calculus and describe the structure-preserving maps or translations between typed lambda calculi. Next we provide a definition of a typed lambda calculus and describe the structure-preserving maps or translations between typed lambda calculi. Having defined the two categories we provide descriptions of functors L : Cart_N to lambda-calc and C: lambda-calc to Cart_N and then show that the functors give an equivalence of categories.

description: Ultralow emittance ($\leq20$ nm, normalized) electron beams with $10^5$ electrons per bunch are obtained by tightly focusing an ultrafast ($\sim$ 100 fs) laser pulse on the cathode of a 1.6 cell radiofrequency photoinjector. Taking advantage of the small initial longitudinal emittance, a downstream velocity bunching cavity is used to compress the beam to $<10$ fs rms bunch length. The measurement is performed using a thick high voltage deflecting cavity which is shown to be well-suited to measure ultrashort durations of bunching beams, provided that the beam reaches a ballistic longitudinal focus at the cavity center.

description: The performance of construction projects is considerably affected by project risks in terms of cost, time and quality. Risks in the construction industry are not limited to construction projects as it is largely presumed. However, construction companies are not observed trying to cope up with them. The objective of the study to assess the risk management practice of 20/80 condominium housing project in Bole Arrabsa-6. The study is of a descriptive type, which made use of both qualitative and quantitative approaches as methodology to address the research objective. Data was collected via semi structured questioners and open-ended interview questions effectively. Among 107 employees working as the contractor and consultant in the companies being involved in the project, questionnaires were distributed to 55 engineers working in different positions and interview was made with the site manager and construction manager. Participants who involved in completing the questioner were selected using purposive sampling. Descriptive statistics was used to summarize the quantitative data compiled by SPSS 21. Data were summarized using measures of central tendency. The study generally revealed that the housing and development agency is practicing risk management in an ad-hoc manner, where there is no well designed and workable policy being implemented to guide the risk management and no enough attention is given to risk planning to channel the risk identification, analysis and response concurrently with the project plan and objective. Based on this finding the study has provided recommendations on how to apply risk management process practice in 20/80 condominium housing project.

description: Background: Giant cell arteritis (GCA) requires rapid diagnosis and treatment to prevent severe complications. However, its low incidence, generic symptoms and nonspecific laboratory markers often result in a diagnostic challenge. The use of a temporal artery biopsy as a gold standard in GCA diagnosis is debatable, as it is time-invasive and has a low sensitivity. The use of imaging techniques is increasingly recognized because they are fast, non-invasive and have a higher sensitivity. However, a direct comparison between these techniques is lacking. This study aims to compare the diagnostic value of ultrasound (US), positron-emission tomography/computed tomography (PET/CT) and magnetic resonance imaging (MRI) with each other. Methods: Patients were recruited for this nested-case control study from a prospective observational cohort study in Hospital Group Twente (ZGT), the ZGT GCA Early in Twente (ZGT-GET) cohort. Demographic and clinical information of patients with suspected GCA is collected. In the present study, 20 patients diagnosed with GCA (GCA+) and 20 patients suspected of but not diagnosed with GCA (GCA-) were included according to baseline diagnosis by the treating rheumatologist. Due to ethical considerations, this rheumatologist had access to all imaging results. Therefore, to avoid bias, the reference diagnosis will be determined by an expert panel based on clinical and laboratory parameters after 6 months follow-up. At baseline, patients underwent standard diagnostic work-up including US of at least the temporal and axillary arteries. A whole body PET/CT and a cranial MRI were performed within one week to minimize influence of treatment. Based on the aforementioned reference diagnosis, sensitivity and specificity of the 3 imaging techniques will be compared. Additional analyses will be performed to assess GCA manifestations and glucocorticoid use. Results: In GCA+ patients, mean age was 72.1 years (SD 7.3) and 55.0% (n=11) were female. In GCA- patients, this was 69.2 years (SD 8.3) and 75.0% (n=15), respectively (Table 1). Follow-up is still ongoing, fortunately the results of the reference diagnosis, sensitivity and specificity of the imaging techniques will be available at the time of the conference. Conclusions: This study compares sensitivity and specificity of US, PET/CT and MRI with each other when 6 months follow-up is available. Direct comparison of diagnostic accuracy is needed to determine the optimal imaging modality for early diagnostics in GCA. Disclosures: none

description: We study toric varieties over an arbitrary field with an emphasis on toric surfaces in the Merkurjev-Panin motivic category of "K-motives". We explore the decomposition of certain toric varieties as K-motives into products of central simple algebras, the geometric and topological information encoded in these central simple algebras, and the relationship between the decomposition of the K-motives and the semiorthogonal decomposition of the derived categories. We obtain the information mentioned above for toric surfaces by explicitly classifying all minimal smooth projective toric surfaces using toric geometry.

When moving the temperature of the black hole, we find rich phase diagrams having, that depend strongly on the dimension of the operator dual to the Proca field . We present different solutions in the bulk that correspond to the holographic dual for $s$, $p$ or $s+p$-wave superfluids. In the last case we observe the onset of a spontaneously induced current.

description: Stochastic behaviors of resistive random access memory (RRAM) play an important role in the design of cross-point memory arrays. A Monte Carlo compact model of oxide RRAM is developed and calibrated with experiments on various device stack configurations. With Monte Carlo SPICE simulations, we show that an increase in array size and interconnect wire resistance will statistically deteriorate write functionality. Write failure probability (WFP) has an exponential dependency on device uniformity and supply voltage (VDD), and the array bias scheme is a key knob. Lowering array VDD leads to higher effective energy consumption (EEC) due to the increase in WFP when the variation statistics are included in the analysis. Random-access simulations indicate that data sparsity statistically benefits write functionality and energy consumption. Finally, we show that a pseudo-sub-array topology with uniformly distributed pre-forming cells in the pristine high resistance state is able to reduce both WFP and EEC, enabling higher net capacity for memory circuits due to improved variation tolerance.

description: Background: Ultrasonography has become the recommended first line investigation for suspected giant cell arteritis (GCA). However, it is still not yet widely available in the UK due to a paucity of skilled rheumatologists. Effective training programmes have been developed, but subsequent hands-on practice is needed to become truly proficient. There is no consensus on the logistics of gaining the ‘appropriate’ level of skill. This project demonstrates a potential mechanism for validation against an expert sonographer. Methods: Over a 6-month period, 12 scans of patients referred with suspected GCA were sequentially performed by first a trainee (FC) and then an expert sonographer (CM) on the same day. FC had theoretical knowledge and supervised practical experience but had not scanned independently prior to this project. CM has performed >1000 scans. 6 vascular territories considered to be the core GCA US data set (common, frontal and parietal branches of the superficial temporal artery, and the 1st, 2nd and 3rd part of the axillary artery) were marked as either ‘normal’ or ‘halo’. CM was blinded to FC’s results. Inter-observer reliability was calculated for all vascular territories using Cohen’s kappa. Results: A total of 144 vascular territories were scanned in 12 patients. Table 1 details the inter-observer variation, with a near perfect level of agreement demonstrated, kappa=0.90 (95% CI 0.83 – 0.98). Conclusions: This is the first study that demonstrates a mechanism for validation of ultrasonography skills which will allow GCA US to become a feasible reality in clinical practice. This project demonstrates that after acquiring supervised training, near perfect levels of agreement can be arrived between a trainee and expert. Disclosures: None Table 1.
