Abstract
Background: Antimicrobial resistance (AmR) is widely considered a global health threat and is associated with significant morbidity, mortality and costs. Inappropriate antimicrobial use is the most important modifiable risk factor for AmR. Most human antimicrobial medicines use occurs in primary care [prescribed by general practitioners (GPs), dispensed by community pharmacists (CPs)]. However, up to 50% of use is deemed inappropriate. Point-of-care diagnostic tests are used as a basis for antimicrobial stewardship interventions to improve the diagnostic certainty of respiratory tract infections (RTIs), and therefore ensure prudent antimicrobial use. However, there is a lack of guidance on their use, and they are therefore not routinely used in clinical practice. Objective: A scoping review will be conducted to synthesise the available evidence to inform the development of best practice guidance for using point-of-care diagnostics in the management of RTIs in primary care. Methods: A scoping review will be conducted following guidance from the Joanna Briggs Institute (JBI) and reported using the PRISMA-ScR guidelines. Databases including Web of Science, MEDLINE, CINAHL, EMBASE, the International HTA database and the Cochrane Central Register of Controlled Trials, as well as grey literature, will be searched. Screening will be undertaken independently by two reviewers to identify studies and literature reporting the use of point-of-care diagnostics in the management of RTIs in primary care by GPs and/ or CPs. Findings will be described using narrative synthesis. Conclusion: The findings of this scoping review will be used to produce draft guidance on the use of point-of-care diagnostic tests in primary care, which will undergo further development using a Delphi consensus methodology involving experts in the field of RTIs, antimicrobial stewardship, point-of-care diagnostics and primary care.

Abstract
Whole blood transfusion is being increasingly used for trauma resuscitation, particularly in military settings. Low-titre group O whole blood simplifies the logistical challenges and maximises the benefits of blood transfusion when compared with component therapy in austere battlefield conditions. Screening protocols and blood testing requirements for prescreened donors in walking blood banks (WBBs), which are used for emergency transfusions, are established by both the USA and most partner nations, though they are not necessarily uniform across these combined forces. Interoperability and standardisation of blood bank resources and protocols across allied forces in multinational military operations, including uniformity in screening processes, collection methods and storage is essential to the provision of safe and effective blood product transfusions in this austere setting. Predeployment screening, multinational training exercises and universal WBB sets with instructions in multiple languages can help enhance the interoperability of combined multinational operations and create a more efficient WBB system. Standardisation of blood collection, nomenclature, equipment and screening practices will allow for the most optimal utilisation of whole blood resources across a multinational battlefield.

Abstract
Spinal cord stimulators (SCS) and peripheral nerve stimulators (PNS) are increasingly used in the treatment of chronic pain, allowing more patients to resume working and return to activities. Military service members face environmental and occupational hazards that expose them to mechanical and electromagnetic forces, both clinical and industrial, that could potentially alter their function. While there are reports of individual hazards, the risk appears to be nominal based on the large number of devices in use and the limited reported complications with these devices. Since a variety of hazards encountered by military patients have the potential to alter SCS and PNS devices, a brief discussion of each patient's specific exposures and related hazards should occur prior to placement. Overall, these devices have demonstrated safety in hazardous areas and few military patients have contraindications for placement based on these factors alone.

Abstract
ABSTRACTThis study compares semantic and phonological interference vulnerability across the full range of learning processes. Method: 43 controls aged 61-88 underwent a neuropsychological examination, French adaptation of the LASSI-L, and an experimental phonological test, the TIP-A. Paired sample t-tests, factorial ANOVA and hierarchical regressions were conducted, psychometric properties were calculated. Results: TIP-A efficiently generated phonological interference between concurrent word lists and was associated with short-term memory, unlike LASSI-L. On LASSI-L, proactive interference was higher than retroactive interference; the opposite pattern was found on TIP-A. Memory performance was better explained by age in the semantic than in the phonological task. Age was not associated with interference vulnerability. Intrusions and false recognition were associated with cognitive functioning regardless of age, particularly in the semantic context. Conclusion: To our knowledge, this is the first study to assess phonological and semantic interference using homologous concurrent word list tasks, and not a working memory build-up or DRM paradigm. The pattern obtained illustrates the weak initial memory trace in a phonological context and results are discussed according to depth-of-processing and dual-process theories. Similar paradigms could be studied among various pathologies for a better understanding of generalised interference vulnerability vs. specific semantic or phonological impairment.

Abstract
The need for changing how science is taught and the expansion of undergraduate research experiences is essential to foster critical thinking in the Natural Sciences. Most faculty research programs only involve a small number of upper-level undergraduate students each semester. The course-based undergraduate research experience (CURE) model enables more students to take ownership over an independent project and experience authentic research. Further, by creating projects that fit into a curriculum's learning goals and student-oriented outcomes, departments help strengthen critical thinking skills in the classroom. Here, we report on the incorporation of a synthetic biology CURE into a mid-level cellular biology course and two advanced level genetics/molecular biology courses. Synthetic biology involves systematic engineering of novel organisms, such as bacteria and plants, to work as functional devices to solve problems in medicine, agriculture, and manufacturing. The value of synthetic biology and its ultimate utility as a teaching tool relies on reusable, standard genetic parts that can be interchanged using common genetic engineering principles. This Synthetic biology CURE effectively achieves five essential goals: (1) a sense of project ownership; (2) self-efficacy: mastery of a manageable number of techniques; (3) increased tolerance for obstacles through challenging research; (4) increased communication skills; and (5) a sense of belonging in a larger scientific community. Based upon our student assessment data, we demonstrate that this course-based synthetic biology laboratory engages students directly in an authentic research experience and models important elements of collaboration, discovery, iteration, and critical thinking.

Abstract
Background For older populations with multimorbidity, polypharmacy (use of multiple medications) is a standard practice. PolyPrime is a theory-based intervention developed to improve appropriate polypharmacy in older people in primary care. This pilot study aims to assess the feasibility of the PolyPrime intervention in primary care in Northern Ireland (NI) and the Republic of Ireland (ROI). Methods This external pilot cluster randomised controlled trial (cRCT) aimed to recruit 12 general practitioner (GP) practices (six in NI; six in the ROI counties that border NI) and ten older patients receiving polypharmacy (≥ 4 medications) per GP practice (n = 120). Practices allocated to the intervention arm watched an online video and scheduled medication reviews with patients on two occasions. We assessed the feasibility of collecting GP record (medication appropriateness, health service use) and patient self-reported data [health-related quality of life (HRQoL), health service use)] at baseline, 6 and 9 months. HRQoL was measured using the EuroQol-5 dimension-5 level questionnaire (EQ-5D-5L) and medication-related burden quality-of-life (MRB-QoL) tool. An embedded process evaluation and health economics analysis were also undertaken. Pre-specified progression criteria were used to determine whether to proceed to a definitive cRCT. Results Twelve GP practices were recruited and randomised. Three GP practices withdrew from the study due to COVID-related factors. Sixty-eight patients were recruited, with 47 (69.1%) being retained until the end of the study. GP record data were available for 47 patients for medication appropriateness analysis at 9 months. EQ-5D-5L and MRB-QoL data were available for 46 and 41 patients, respectively, at 9 months. GP record and patient self-reported health service use data were available for 47 patients at 9 months. Health service use was comparable in terms of overall cost estimated from GP record versus patient self-reported data. The intervention was successfully delivered as intended; it was acceptable to GPs, practice staff, and patients; and potential mechanisms of action have been identified. All five progression criteria were met (two ‘Go’, three ‘Amend’). Conclusion Despite challenges faced during the COVID-19 pandemic, this study has demonstrated that it may be feasible to conduct an intervention to improve appropriate polypharmacy in older people in primary care across two healthcare jurisdictions.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
BACKGROUND A range of 'field-directed' treatments is available for the management of extensive skin field cancerization (ESFC), but to date, the only validated objective quantitative tools are limited to assessment of actinic keratoses (AKs) affecting the head. AIMS To develop a versatile quantitative instrument for objective clinical assessment of ESFC and perform initial internal validation across multiple anatomical zones. METHODS The study comprised instrument development, pilot testing and instrument refinement and two rounds of reliability and inter-rater validation testing. The study was noninterventional and used a convenience sample of de-identified patient photographs selected based on preset criteria. An expert panel developed the instrument and scoring system via a modified Delphi voting process. A sample of 16 healthcare professionals from multiple specialties undertook the pilot testing, and a panel of seven dermatologists were involved in validation testing. Validation was determined by assessment of overall inter-rater agreement using Gwet chance-corrected agreement coefficients (ACs). RESULTS The instrument produced, called the Method for Assessing Skin Cancer and Keratoses™ (MASCK™), comprises the Skin Field Cancerization Index (SFCIndex), derived from area of skin involvement and AKs (number and thickness), a global assessment score and a cancer-in-zone score, and uses Likert scales for quantitative scoring. The SFCIndex is a composite score comprising the number and thickness of AKs multiplied by area of skin involvement. ACs for the SFCIndex components, the overall SFCIndex score and the global assessment score were > 0.80 (rated 'almost perfect') while the AC for the cancer-in-zone metric was lower (0.33, rated 'fair'). Internal consistency was demonstrated via positive correlation between the overall SFCIndex score and the global assessment score. CONCLUSIONS Our study found near-perfect agreement in inter-rater reliability when using MASCK to assess the severity of ESFC in multiple anatomical sites. Further validation of this novel instrument is planned to specifically assess its reliability, utility and feasibility in clinical practice.

Abstract
BackgroundAutoimmune diseases represent a large and heterogeneous group of disorders that afflict specific target organs. However, multiple factors point to common links between the differing presentations of autoimmune disorders.With increased interest in further understanding the neuro-immune axis, autoimmune diseases represent an important opportunity to explore whether systemic inflammation from these autoimmune pathways has a central effect and, if so, whether there is a common or discrete central effect caused by different autoimmune diseases.ObjectivesThe present study aimed to analyse hippocampal volume in patients with rheumatoid arthritis (RA) and ulcerative colitis (UC) as compared to healthy control groups. The hippocampus was chosen as a region of interest given the regulatory role it exhibits in the hypothalamic–pituitary–adrenal (HPA) axis2. Additionally, the hippocampus has been identified as a region that is affected in other autoimmune diseases such as systemic lupus erythematosus (SLE).MethodsData from 1,040 individuals in the UKBiobank Imaging sub-study were included in the present study. This was divided into two separate patient populations with separate control groups. Data from 267 individuals (mean age ± SD =65.52 ± 7.02, 70.8% females) were included in the RA patient group with 267 age and sex matched controls (mean age ± SD = 65.51 ± 7, 70.8% females). Data from 253 individuals (mean age ± SD = 64.09 ± 7.03, 51.6% females) were included in the UC patient group with 253 age and sex matched controls (mean age ± SD = 63.4 ± 7.02, 51.6% females).The UKBiobank is a prospective observational study with a proposed cohort of 500,000 participants. The imaging substudy is planned to scan 100,000 of those participants with a standardised scanning protocol including MRI of the brain. Multi-modal images were acquired on a 3T scanner3. From the T1w data, volumetric imaging derived phenotypes (IDPs) are provided using the FMRIB Integrated Registration and Segmentation Tool (FIRST); http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FIRST. This study utilised the right and left hippocampal volume outputs from that tool.ResultsWe observed a smaller hippocampal volume in UC patients when compared to healthy controls (difference right: 99.78 mm3, SD ± 38.97, p = 0.01; left: 74.30 mm3, SD ± 39.41, p = 0.06). The Cohen’s effect size was d = -0.24 [95% CI -0.43, -0.05] for right hippocampal volume and d = -0.18 [95% CI -0.36, 0.00] for left hippocampal volume.Figure 1.Right and left hippocampal volume in UC patients versus controls and right and left hippocampal volume in RA patients versus controls.There was no significant difference seen in hippocampal volume in RA patients compared to controls (difference right: 61.32 mm3, SD ± 40.33, p = 0.13; left: 39.00 mm3, SD ± 38.19, p = 0.31). The Cohen’s effect size was d = -0.12 [95% CI -0.30, 0.06] for right hippocampal volume and d = -0.08 [95% CI -0.27, 0.10] for left hippocampal volume.ConclusionThis study provides evidence of moderate reduction in hippocampal volumes in patients with ulcerative colitis as compared to age and sex matched healthy controls. This same effect was not seen in a similarly matched rheumatoid arthritis patient population. Further analysis of additional subcortical regions could provide further context for whether there are alternative regions affected in both RA and UC.References[1]Bellavance, M.A, Rivest, S., (2014), ‘The HPA – immune axis and the immunomodulatory actions of glucocorticoids in the brain’, Frontiers in Immunology, vol, 5, pp 136.[2]Miller, K.L., Alfaro-Almagro, F., Bangerter, N.K. et al.

Abstract
Integral membrane proteins in the G Protein-Coupled Receptor (GPCR) class are attractive drug development targets. However, computational methods applicable to ligand discovery for many GPCR targets are restricted by limited numbers of known ligands. Pharmacophore models can be developed using variously sized training sets and applied in database mining to prioritize candidate ligands for subsequent validation. This in silico study assessed the impact of key pharmacophore modeling decisions that arise when known ligand numbers for a target of interest are low. GPCR included in this study are the adrenergic alpha-1A, 1D and 2A, adrenergic beta 2 and 3, kappa, delta and mu opioid, serotonin 1A and 2A, and the muscarinic 1 and 2 receptors, all of which have rich ligand data sets suitable to assess the performance of protocols intended for application to GPCR with limited ligand data availability. Impact of ligand function, potency and structural diversity in training set selection was assessed to define when pharmacophore modeling targeting GPCR with limited known ligands becomes viable. Pharmacophore elements and pharmacophore model selection criteria were also assessed. Pharmacophore model assessment was based on percent pharmacophore model generation failure, as well as Güner-Henry enrichment and goodness-of-hit scores. Three of seven pharmacophore element schemes evaluated in MOE 2018.0101, Unified, PCHD, and CHD, showed substantially lower failure rates and higher enrichment scores than the others. Enrichment and GH scores were used to compare construction protocol for pharmacophore models of varying purposes- such as function specific versus nonspecific ligand identification. Notably, pharmacophore models constructed from ligands of mixed functions (agonists and antagonists) were capable of enriching hitlists with active compounds, and therefore can be used when available sets of known ligands are limited in number.

Abstract
INTRODUCTION Plane blocks are an increasingly common type of regional anaesthesia technique in the perioperative period. Increased spread of local anaesthesia during plane blocks is thought to be related to an increased area of pain coverage. This study sought to assess differences in injectate spread comparing Tuohy needles with standard insulated stimulating block needles. METHODS 10 Yorkshire-Cross porcine cadavers were used in this study. Immediately following euthanasia, the cadavers underwent bilateral ultrasound-guided transversus abdominis plane (TAP) block injection with radiopaque contrast dye, with one side placed with a 20 g Tuohy needle, and the other side with a 20 g insulated stimulating block needle. Injectate spread was assessed using plain film X-ray and area of spread was measured to compare differences. RESULTS All 10 animals underwent successful ultrasound-guided TAP block placement. In all 10 animals, the area of contrast spread was greater with the Tuohy than stimulating needle. Wilcoxon signed-rank test was used to analyse the difference between the groups. The average difference between the two sides was 33.02% (p=0.002). CONCLUSIONS This is the first study to demonstrate differences in injectate spread with different needle types. This suggests enhanced spread with Tuohy needle compared with standard block needle, and may encourage its use during plane blocks.

Abstract
BACKGROUND/OBJECTIVES Vulval lichen sclerosus (VLS) is a chronic inflammatory skin condition predominantly affecting the anogenital region in women and children. To date, there is lack of agreement amongst experts on a severity scale to aid assessment, research and treatment stratification on VLS. Furthermore, literature on best practice for long-term management of VLS is lacking. The aim of this consensus is to provide broad guidelines on the short and long-term management of VLS. METHODS An initial focus group of Australasian experts in vulval dermatology developed a draft consensus statement for the management of VLS. Based on the results of the draft statement, a consensus panel of 22 Australasian experts, comprised of the initial and additional members, participated in an anonymous four-stage eDelphi process. Round 1 involved generation and voting on statements from the draft consensus statement developed by the focus group. In Rounds 2, 3 & 4, panel members were presented formal feedback from previous rounds and asked to indicate their level of agreement. Consensus was reached if there was ≥70% agreement on the importance of an item in the 4 (agree) to 5 (strongly agree) range. RESULTS The expert panel, with a total of 504 collective years of experience in the field of VLS, reached consensus on a core set of 51 management statements related to diagnosis, severity, initial and long-term management, follow-up, and complications of VLS. CONCLUSIONS This study has identified a set of management statements for VLS that may be useful in clinical practice in the Australasian population.

Abstract
BACKGROUND A subset of individuals with type 1 diabetes mellitus (T1DM) are predisposed to developing diabetic kidney disease (DKD), the most common cause globally of end-stage kidney disease (ESKD). Emerging evidence suggests epigenetic changes in DNA methylation may have a causal role in both T1DM and DKD. The aim of this exploratory investigation was to assess differences in blood-derived DNA methylation patterns between individuals with T1DM-ESKD and individuals with long-duration T1DM but no evidence of kidney disease upon repeated testing to identify potential blood-based biomarkers. Blood-derived DNA from individuals (107 cases, 253 controls and 14 experimental controls) were bisulphite treated before DNA methylation patterns from both groups were generated and analysed using Illumina's Infinium MethylationEPIC BeadChip arrays (n = 862,927 sites). Differentially methylated CpG sites (dmCpGs) were identified (false discovery rate adjusted p ≤ × 10-8 and fold change ± 2) by comparing methylation levels between ESKD cases and T1DM controls at single site resolution. Gene annotation and functionality was investigated to enrich and rank methylated regions associated with ESKD in T1DM. RESULTS Top-ranked genes within which several dmCpGs were located and supported by functional data with methylation look-ups in other cohorts include: AFF3, ARID5B, CUX1, ELMO1, FKBP5, HDAC4, ITGAL, LY9, PIM1, RUNX3, SEPTIN9 and UPF3A. Top-ranked enrichment pathways included pathways in cancer, TGF-β signalling and Th17 cell differentiation. CONCLUSIONS Epigenetic alterations provide a dynamic link between an individual's genetic background and their environmental exposures. This robust evaluation of DNA methylation in carefully phenotyped individuals has identified biomarkers associated with ESKD, revealing several genes and implicated key pathways associated with ESKD in individuals with T1DM.

Abstract
Background There is a high prevalence of COVID-19 in university-age students, who are returning to campuses. There is little evidence regarding the feasibility of universal, asymptomatic testing to help control outbreaks in this population. This study aimed to pilot mass COVID-19 testing on a university research park, to assess the feasibility and acceptability of scaling up testing to all staff and students. Methods This was a cross-sectional feasibility study on a university research park in the East of England. All staff and students (5625) were eligible to participate. All participants were offered four PCR swabs, which they self-administered over two weeks. Outcome measures included uptake, drop-out rate, positivity rates, participant acceptability measures, laboratory processing measures, data collection and management measures. Results 798 (76%) of 1053 who registered provided at least one swab; 687 (86%) provided all four; 792 (99%) of 798 who submitted at least one swab had all negative results and 6 participants had one inconclusive result. There were no positive results. 458 (57%) of 798 participants responded to a post-testing survey, demonstrating a mean acceptability score of 4.51/5, with five being the most positive. Conclusions Repeated self-testing for COVID-19 using PCR is feasible and acceptable to a university population.

Abstract
AIMS Existing methods for the identification of the subspecies of Xylella fastidiosa are time-consuming which can lead to delays in diagnosis and the associated plant health response to outbreaks and interceptions. METHODS AND RESULTS Diagnostic markers were identified using a comparative genomics approach to allow fine differentiation of the very closely related subspecies. Five qPCR assays were designed to allow specific detection of X. fastidiosa subsp. fastidiosa, X. fastidiosa subsp. multiplex, X. fastidiosa subsp. pauca, X. fastidiosa subsp. morus and X. fastidiosa subsp. sandyi. All assays were validated according to the European and Mediterranean Plant Protection Organisation (EPPO) standard PM7/98(2). CONCLUSIONS All of the assays were shown to be specific to the target subspecies and all the assays could be used to detect femtogram quantities of X. fastidiosa DNA. SIGNIFICANCE AND IMPACT OF THE STUDY At present, diagnosing the subspecies of X. fastidiosa requires multiple conventional PCR assays (although only available for three of the five subspecies) or multi-locus sequence typing which takes several days. By comparison, the new assays provide a substantial reduction in the turnaround time for direct identification to the subspecies level in as little as 75 min.

Abstract
Holstein haplotype 2 (HH2) is embryonic lethal and carried by 1.21% of the US Holstein population. Using next-generation sequencing, we identified a high-impact frameshift mutation in intraflagellar protein 80 (IFT80) as the putative causal mutation. In bovine embryos, IFT80 expression begins at the 8-cell stage and decreases by the blastocyst stage. We hypothesised that the loss of function of IFT80 early in development causes the lethal phenotype. The aim of this study was to mimic the mutation observed invivo using a CRISPR-Cas9 approach to determine its effect on embryo development. Two guide RNAs (gRNAs) were designed to disrupt exon 11 (Ex11), one before and one after the known IFT80 mutation site, creating a 317-nucleotide (nt) cut to facilitate genotyping. Then, gRNAs annealed to a tracr-Cas9mRNA complex were delivered to 1-cell embryos by microinjection. Each replicate contained control embryos injected with only Cas9mRNA and treated embryos injected with gRNAs targeting IFT80. Embryos from each group were collected at the 8-cell stage for genotyping and gene expression analysis (n=47), or on Day 8 to validate genotypes of embryos left to develop (n=50). DNA sequences containing gRNA target sequences were amplified and visualised on an agarose gel. IFT80 expression was determined in biallelic embryos (n=13) using quantitative PCR and normalized to GAPDH. Primers were designed for the transcript regions before and after gRNAs target sequences, exons 9 and 12, respectively. Expression data were analysed using SAS software (v. 9.4; SAS Institute Inc.) using PROC GLM and LSMEANS to determine expression differences. Biallelic samples (n=9) were Sanger-sequenced (SS) and aligned with the reference sequence to determine exact cut sites. Protein amino acid (AA) sequences were predicted using SS data. Protein models were constructed using the I-Tasser platform, and then aligned and visualised using PyMol 2.4. Biallelic edits showed a significant decrease in exon 12 expression (P<0.05), and no difference in exon 9 compared with controls (P>0.05), indicating that the transcript was severely affected downstream of the edited sites. The reference protein model contained 777 AA, whereas the biallelic sample with the most accurate cut sites yielded a 385-AA protein, indicating that the mutation severely altered protein conformation and possible function. Embryos injected with CRISPR-Cas9 targeting Ex11 arrested at the 8-cell stage and failed to form blastocysts. Day 8 embryos were genotyped (n=24) and 58% were biallelic, 21% were monoallelic, and 21% appeared wild-type. Given the high rate of edits, the observed embryonic arrest is likely due to disruption of IFT80, and wild-type embryos may contain small edits not visible by gel. In conclusion, generation of CRISPR-Cas9 IFT80 knockouts demonstrated that the frameshift mutation in Ex11 results in a seemingly nonfunctional protein that is responsible for the embryonic lethality seen in HH2 carriers. Future research is needed to determine how IFT80 regulates embryonic development.

Abstract
Background:Skin in people with psoriasis has been comprehensively studied; uninvolved skin has abnormal gene expression. Less is known specifically about skin in PsA, the assumption being that it is identical to psoriasis. Chemokines and ACKR2 are among the upregulated genes in uninvolved psoriasis compared to healthy skin[1]. ACKR2 is a scavenging receptor of inflammatory CC chemokines and has been proposed as a regulator of cutaneous inflammation in psoriasis. It has not been studied in PsA.Objectives:To compare the transcriptome of PsA lesional, PsA uninvolved and healthy control skin and evaluate ACKR2 expression in PsA.Methods:Biopsies were taken from healthy control (HC) skin and paired lesional and uninvolved skin from patients with PsA. Libraries for bulk RNA sequencing were prepared from polyA selected RNA and sequenced on NovaSeq 6000. Sequencing data were analysed using Searchlight2. ACKR2 mRNA expression was validated by qPCR. RNAscope was used to localise ACKR2 expressing cells and sections were co-stained with podaplanin or stained in serial sections with CD45. Chemokine protein expression in skin was evaluated using Luminex technology.Results:Nine HC and 9 paired skin samples from patients with PsA were sequenced. The PsA skin lesions (PsA L) formed a distinct population in the transcriptomic principal component analysis (PCA) plot while HC and PsA uninvolved skin (PsA U) were overlapping. Only 15 genes were differentially expressed between HC and PsA U and none coded for chemokines. There were however significantly upregulated chemokines and receptors in PsA L. Unexpectely, ACKR2 was the 2ndmost upregulated chemokine receptor in PsA L with unchanged expression in PsA U compared with HC (PsA L vs HC log2fold 3.38, p.adj=9.51E-41; PsA L vs PsA U log2fold 3.58, p.adj=3.24E-45; PsA U vs HC log2fold -0.2, p.adj=0.732).The upregulation of ACKR2 in PsA L and unchanged expression in PsA U was confirmed by qPCR. RNAscope demonstrated strong expression of ACKR2 in the suprabasal layer of the epidermis in PsA L. In HC and PsA U, only occasional ACKR2 positive cells were seen in the epidermis. ACKR2 was expressed in lymphatic vessel walls but was not observed in CD45+ leukocytes.Provisional skin chemokine protein expression data showed poor correlation between mRNA levels and protein expression for the ACKR2 ligands CCL2, CCL3, CCL7, CCL8, CCL11, CCL13 and CCL22 in HC and PsA U, with negative correlation between ACKR2 mRNA expression and CCL2, CCL8 and CCL11 protein expression. In PsA L, chemokine mRNA correlated with protein expression, but protein expression of chemokine ligands did not correlate with ACKR2 expression.Conclusion:This data set shows expected upregulation of chemokines and their receptors in PsA L but relatively unchanged gene expression in PsA U, which contrasts to previous studies in psoriasis. Notably, this study demonstrates a strong upregulation of ACKR2 in keratinocytes in PsA L, with unchanged expression in PsA U. The RNA expression and preliminary protein data suggest that ACKR2 has little effect on the levels of its ligands in PsA skin lesions. However, this study may have missed local effects of ACKR2 in the epidermis.References:[1]Singh, M.D., et al.,Elevated expression of the chemokine-scavenging receptor D6 is associated with impaired lesion development in psoriasis.Am J Pathol, 2012.181(4): p. 1158-64.Acknowledgments:Funded by the Chief Scientist Office and a private donation to the University of Glasgow.

Abstract
We introduce the Clouds Above the United States and Errors at the Surface (CAUSES) project with its aim of better understanding the physical processes leading to warm screen temperature biases over the American Midwest in many numerical models. In this first of four companion papers, 11 different models, from nine institutes, perform a series of 5 day hindcasts, each initialized from reanalyses. After describing the common experimental protocol and detailing each model configuration, a gridded temperature data set is derived from observations and used to show that all the models have a warm bias over parts of the Midwest. Additionally, a strong diurnal cycle in the screen temperature bias is found in most models. In some models the bias is largest around midday, while in others it is largest during the night. At the Department of Energy Atmospheric Radiation Measurement Southern Great Plains (SGP) site, the model biases are shown to extend several kilometers into the atmosphere. Finally, to provide context for the companion papers, in which observations from the SGP site are used to evaluate the different processes contributing to errors there, it is shown that there are numerous locations across the Midwest where the diurnal cycle of the error is highly correlated with the diurnal cycle of the error at SGP. This suggests that conclusions drawn from detailed evaluation of models using instruments located at SGP will be representative of errors that are prevalent over a larger spatial scale.

Abstract
Background The Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 instrument (MDF-Fibro-17) has been developed for use in fibromyalgia (FM) clinical studies and includes 5 domains: Global Fatigue Experience, Cognitive Fatigue, Physical Fatigue, Motivation, and Impact on Function. Psychometric properties of the MDF-Fibro-17 needed to demonstrate the appropriateness of using this instrument in clinical studies are presented. Methods Psychometric analyses were conducted to evaluate the factor structure, reliability, validity, and responsiveness of the MDF-Fibro-17 using data from a Phase 2 clinical study of FM patients (N = 381). Confirmatory factor analyses (CFA) were performed to ensure understanding of the multidimensional domain structure, and a secondary factor analysis of the domains examined the appropriateness of calculating a total score in addition to domain scores. Longitudinal psychometric analyses (test-retest reliability and responder analysis) were also conducted on the data from Baseline to Week 6. Results The CFA supported the 17-item, 5 domain structure of this instrument as the best fit of the data: comparative fit index (CFI) and non-normed fit index (NNFI) were 0.997 and 0.992 respectively, standardized root mean square residual (SRMR) was 0.010 and the root mean square error of approximation (RMSEA) was 0.06. In addition, total score (CFI and NNFI both 0.95) met required standards. For the total and 5 domain scores, reliability and validity data were acceptable: test-retest and internal consistency were above 0.9; correlations were as expected with the Global Fatigue Index (GFI) (0.62-0.75), Fibromyalgia Impact Questionnaire (FIQ) Total (0.59–0.71), and 36-Item Short Form Health Survey (SF-36) vitality (VT) (0.43–0.53); and discrimination was shown using quintile scores for the GFI, FIQ Total, and Pain Numeric Rating Scale (NRS) quartiles. In addition, sensitivity to change was demonstrated with an overall mean responder score of -2.59 using anchor-based methods. Conclusion The MDF-Fibro-17 reliably measures 5 domains of FM-related fatigue and psychometric evaluation confirms that this measure meets or exceeds each of the predefined acceptable thresholds for evidence of reliability, validity, and responsiveness to changes in clinical status. This suggests that the MDF-Fibro-17 is an appropriate and responsive measure of FM-related fatigue in clinical studies.

Abstract
PURPOSE Women with metastatic triple negative breast cancer (TNBC) can have a poor prognosis with treatment limited to cytotoxic chemotherapy. The identification of effective therapies that may limit exposure to cytotoxic chemotherapy and lead to prolonged survival is an unmet medical need. We tested an inhibitor of the epidermal growth factor receptor, panitumumab in combination with chemotherapy. METHODS We conducted a single arm clinical trial in women with metastatic or locally advanced TNBC to paclitaxel 80 mg/m2 and carboplatin AUC of 2 on days 1, 8, and 15 and panitumumab 6 mg/kg on days 1 and 15 for a cycle length of 28 days. The objectives were to evaluate the response rate and safety of the combination in comparison to historical controls. RESULTS Fourteen patients with TNBC were enrolled with a median age of 53 years. The majority of women were African American (64.3%) with visceral metastasis (64.2%). Hematologic toxicities, particularly neutropenia and thrombocytopenia, were a major cause of missed chemotherapy and delayed treatment in this study. The overall response rate (complete and partial response) of the 13 evaluable patients was 46%. The median time to best response was 2.4 months and the median time to disease progression was 3.6 months. We were able to perform the PAM50 analysis on tumors from 7 of our subjects. All the samples tested clustered within the basal-like subtype. CONCLUSIONS In our experience the response rate of carboplatin, paclitaxel and panitumumab was consistent with other reports of response for cytotoxic chemotherapy in metastatic TNBC.

Abstract
BACKGROUND New treatment options are required for patients with asthma not sufficiently controlled with inhaled therapies. In a Phase 2a trial, CYT003, a Toll-like receptor-9 agonist immunomodulator, improved asthma control during inhaled glucocorticosteroid reduction in patients with allergic asthma. This double-blind Phase 2b study assessed the efficacy and safety of CYT003 in patients with persistent moderate-to-severe allergic asthma not sufficiently controlled on standard inhaled glucocorticosteroid therapy with/without long-acting beta-agonists (LABAs). METHODS Overall, 365 patients received seven doses of subcutaneous CYT003 (0.3, 1, or 2 mg) or placebo as add-on therapy to conventional controller medication. Change from baseline in Asthma Control Questionnaire (ACQ) score was the primary outcome; secondary outcomes included change in forced expiratory volume, Mini Asthma Quality of Life Questionnaire, and safety. RESULTS All groups, including placebo, showed a clinically important improvement in ACQ score; however, there was no significant difference between the CYT003 and placebo groups at week 12 (least-squares mean difference 0.3 mg: -0.027 [95% confidence interval -0.259 to 0.204]; 1 mg: 0.097 [-0.131 to 0.325]; 2 mg: 0.081 [-0.148 to 0.315]). No significant differences were seen in secondary outcomes. CYT003 was well tolerated; the most common treatment-emergent adverse events were injection site reactions. Due to lack of efficacy, the study was prematurely terminated at the end of the treatment phase with no further follow-up. CONCLUSIONS Toll-like receptor-9 agonism with CYT003 showed no additional benefit in patients with insufficiently controlled moderate-to-severe allergic asthma receiving standard inhaled glucocorticosteroid therapy with or without LABAs.
