- Abstract
Objectives: The impact of autoantibody profiles on the prognosis for idiopathic inflammatory myositis-associated interstitial lung disease (IIM-ILD) and myositis spectrum ILD with myositis-specific antibodies (MSAs) remains unclear. This retrospective cohort study examined whether serological profiles were associated with mortality or longitudinal lung function change., Methods: The baseline clinical/demographic characteristics and follow-up lung function data of consecutive adult patients with IIM-ILD or interstitial pneumonia with autoimmune features (IPAF) positive for MSAs (IPAF-MSA) were extracted from three hospitals. Univariate and multivariate Cox proportional hazards analyses were used to compare mortality between groups of patients with different autoantibodies. Regression models were used to analyse their lung function trends., Results: Of the 430 included patients, 81% met the IIM criteria, and the remaining 19% were diagnosed with IPAF-MSA. On univariate analysis, the risk factors associated with mortality included higher age, Charlson Comorbidity Index, and CRP; and lower BMI, baseline TLCO% and FEV1%. Compared with anti-MDA5 negativity, anti-MDA5 positivity (MDA5+) was associated with higher mortality in the first 3 months [hazard ratio (HR) 65.2, 95% CI 14.1, 302.0], while no significant difference was seen thereafter (HR 0.55, 95% CI 0.14, 2.28). On multivariate analysis, combined anti-synthetase antibodies were associated with a reduced risk of mortality (HR 0.63), although individually, mortality was reduced in patients with anti-Jo1+ (HR 0.61, 95% CI 0.4-0.87) and increased in patients with anti-PL7+ (HR 2.07, 95% CI 1.44-2.99). Anti-MDA5+ was associated with slow improvement in %FVC over the first 3 years, while anti-PL7+ was linked with a slow decline from 12 months onwards., Conclusion: Among the autoantibody profiles in myositis spectrum disorders, anti-MDA5+ and anti-PL7+ conferred higher mortality risks in patients with IIM-ILD. Survivors of an early peak of mortality in anti-MDA5+ disease appeared to have a favourable prognosis., (© The Author(s) 2023.

- Abstract
Objective: To evaluate the safety, efficacy, tolerability, and cost-effectiveness of bedside or office-based ureteric stent insertion., Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Protocols (PRISMA-P) and A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 guidelines, we searched PubMed/the Medical Literature Analysis and Retrieval System Online (MEDLINE), the Excerpta Medica dataBASE (EMBASE), Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL), and Dimensions for English-language studies from 1978 to April 2023. Inclusion criteria focused on primary ureteric stent placements outside of the operating theatre (OT)., Results: A total of 15 studies involving 2072 stents were included. Success rates for correctly positioned stents in bedside or office-based insertions ranged from 60% to 95.8%, with most studies reporting ≥80% success rates. Common failure reasons included impacted stones and difficulty identifying the ureteric orifice. Pain and tolerability were assessed using various methods, with validated tools indicating moderate pain levels, but most patients would undergo the procedure again under local anaesthesia. Complication rates were generally low, with minor complications such as haematuria or postoperative fever being the most common. Procedural costs were significantly lower in non-OT settings, with estimates indicating savings of up to four-fold., Conclusion: Bedside or office-based ureteric stent insertion is a viable alternative to OT procedures, offering high success rates, manageable pain levels, low complication rates, and substantial cost savings. This approach is particularly advantageous in settings with limited OT access, highlighting its potential for broader adoption in urological practice. Future research should focus on standardising pain assessment methods and randomised studies., (© 2024 The Author(s).

- Abstract
Introduction: Volatile organic compounds (VOCs) can arise from underlying metabolism and are detectable in exhaled breath, therefore offer a promising route to non-invasive diagnostics. Robust, precise, and repeatable breath measurement platforms able to identify VOCs in breath distinguishable from background contaminants are needed for the confident discovery of breath-based biomarkers., Objectives: To build a reliable breath collection and analysis method that can produce a comprehensive list of known VOCs in the breath of a heterogeneous human population., Methods: The analysis cohort consisted of 90 pairs of breath and background samples collected from a heterogenous population. Owlstone Medical's Breath Biopsy
® OMNI® platform, consisting of sample collection, TD-GC-MS analysis and feature extraction was utilized. VOCs were determined to be "on-breath" if they met at least one of three pre-defined metrics compared to paired background samples. On-breath VOCs were identified via comparison against purified chemical standards, using retention indexing and high-resolution accurate mass spectral matching., Results: 1471 VOCs were present in > 80% of samples (breath and background), and 585 were on-breath by at least one metric. Of these, 148 have been identified covering a broad range of chemical classes., Conclusions: A robust breath collection and relative-quantitative analysis method has been developed, producing a list of 148 on-breath VOCs, identified using purified chemical standards in a heterogenous population. Providing confirmed VOC identities that are genuinely breath-borne will facilitate future biomarker discovery and subsequent biomarker validation in clinical studies. Additionally, this list of VOCs can be used to facilitate cross-study data comparisons for improved standardization., (© 2024. The Author(s).)- Published

- Abstract
Background: Male factor infertility affect up to 50% of couples unable to conceive spontaneously. Several non-hormonal pharmacological treatments have been proposed to boost spermatogenesis and increase chances of conception in men with infertility. Still, no clear evidence exists on the most effective treatment strategy., Objective: We aimed to compare the effectiveness of non-hormonal pharmacological treatment options for men with infertility using a systematic review and network meta-analysis., Methods: We searched MEDLINE, EMBASE, and CENTRAL until October 2023 for randomised/quasi-randomised trials that evaluated any non-hormonal pharmacological treatment options for men with idiopathic semen abnormalities or those with hypogonadism. We performed pairwise and network meta-analyses using a random effect model. We assessed risk of bias, heterogeneity, and network inconsistency. We calculated the mean rank and the surface under the cumulative ranking curve (SUCRA) for each intervention the maximum likelihood to achieve each of reported outcomes. We reported primarily on sperm concentration and other important semen and biochemical outcomes using standardised mean difference (SMD) and 95% confidence-intervals(CI)., Results: We included 14 randomised trials evaluating four treatments (Clomiphene citrate, Tamoxifen, Aromatase inhibitors, anti-oxidants) and their combinations in 1342 men. The overall quality of included trials was low. Sperm concentration improved with clomiphene compared to anti-oxidants (SMD 2.15, 95%CI 0.78-3.52), aromatase inhibitor (SMD 2.93, 95%CI 1.23-4.62), tamoxifen (SMD - 1.96, 95%CI -3.57; -0.36) but not compared to placebo (SMD - 1.53, 95%CI -3.52- 0.47). Clomiphene had the highest likelihood to achieve the maximum change in sperm concentration (SUCRA 97.4). All treatments showed similar effect for sperm motility, semen volume, and normal sperm morphology. FSH levels showed significant improvement with clomiphene vs.anti-oxidant (SMD 1.48, 95%CI 0.44-2.51) but not compared to placebo. The evidence networks for LH and testosterone suffered from significant inconsistency (p = 0.01) with similar trend of improvement with clomiphene compared to other treatments but not compared to placebo., Conclusion: There is insufficient evidence to support the routine use of Clomiphene, tamoxifen, and aromatase inhibitors to optimise semen parameters in men with infertility. Future randomised trials are needed to confirm the efficacy of clomiphene in improving fertility outcomes in men., Prospero: CRD42023430179., (© 2024. The Author(s).)

- Abstract
Cardiac involvement in idiopathic inflammatory myopathies (IIM) purports to worse clinical outcomes, and therefore early identification is important. Research has focused on blood biomarkers and basic investigations such as ECG and echocardiography, which have the advantage of wide availability and low cost but are limited in their sensitivity and specificity. Imaging the myocardium to directly look for inflammation and scarring has therefore been explored, with a number of new methods for doing this gaining wider research interest and clinical availability. Cardiovascular magnetic resonance (CMR) with contemporary multiparametric mapping techniques and late gadolinium enhancement imaging, is an extremely valuable and increasingly used non-invasive imaging modality for the diagnosis of myocarditis. The recently updated CMR-based Lake Louise Criteria for the diagnosis of myocarditis incorporate the newer T1 and T2 mapping techniques, which have greatly improved the diagnostic accuracy for IIM myocarditis.18F-FDG-PET/CT is a well-utilized imaging modality in the diagnosis of malignancies in IIM, and it also has a role for the diagnosis of myocarditis in multiple systemic inflammatory diseases. Endomyocardial biopsy, however, remains the gold standard technique for the diagnosis of myocarditis and is necessary for the diagnosis of specific cases of myocarditis. This article provides an overview of the important tests and imaging modalities that clinicians should consider when faced with an IIM patient with potential myocarditis., (© The Author(s) 2024.

- Abstract
ObjectiveTo assess whether prostate biopsy rates have altered with the July 2018 change in Australian Medicare Benefits Schedule (MBS) rebates supporting multiparametric magnetic resonance imaging (mpMRI) for diagnosing prostate cancer.MethodsBiopsy data (both trans-rectal and trans-perineal) were obtained from the Victorian Agency for Health Information from July 2016 to June 2022. The data were stratified by financial year, age group and hospital type (public vs private). Comparison was made between rates pre and post the mpMRI MBS code change.ResultsThere was an 11.9% increase in the number of biopsies performed per year compared to the pre-MBS change period. There is a significant decreasing trend (P<0.001-4) in number of biopsies in the 40-49, 50-59 and 60-69-year-old age groups with a significant increasing trend (P<0.001) in the 70-79 and 80-89-year-old age groups. There was a 32.9% reduction in the mean number of biopsies performed per year in public hospitals, compared with an 18.3% increase in private.ConclusionContrary to expectations, and proposed funding, there has been an increase in the number of prostate biopsies since MRI became more easily available. This change will put increased pressure on the health budget and the large increase in biopsies in elderly patients was not anticipated when the changes were proposed. A review of the criteria is suggested.

- Abstract
Utilizing a multidisciplinary approach to identify catheter-associated urinary tract infection (CAUTI) risks in Neuroscience intensive care patients admitted for aneurysmal subarachnoid hemorrhage, our CAUTI rate decreased from 5.903 per 1,000 catheter days (June 2020-June 2021) to 0.371 per 1,000 catheter days in our postintervention time period (July 2021-March 2023). A review of our clinical treatment guideline to optimize the timing of indwelling urinary catheters and medication management related to bowel regimens has resulted in a sustained CAUTI reduction, particularly in postaneurysmal subarachnoid hemorrhage patients in the Neuroscience intensive care unit., (Copyright © 2023 Association for Professionals in Infection Control and Epidemiology, Inc.

- Abstract
Adult-onset idiopathic inflammatory myopathy (IIM) is associated with an increased cancer risk within the 3 years preceding and following IIM onset. Evidence- and consensus-based recommendations for IIM-associated cancer screening can potentially improve outcomes. This International Guideline for IIM-Associated Cancer Screening provides recommendations addressing IIM-associated cancer risk stratification, cancer screening modalities and screening frequency. The international Expert Group formed a total of 18 recommendations via a modified Delphi approach using a series of online surveys. First, the recommendations enable an individual patient's IIM-associated cancer risk to be stratified into standard, moderate or high risk according to the IIM subtype, autoantibody status and clinical features. Second, the recommendations outline a 'basic' screening panel (including chest radiography and preliminary laboratory tests) and an 'enhanced' screening panel (including CT and tumour markers). Third, the recommendations advise on the timing and frequency of screening via basic and enhanced panels, according to risk status. The recommendations also advise consideration of upper or lower gastrointestinal endoscopy, nasoendoscopy and
18 F-FDG PET-CT scanning in specific patient populations. These recommendations are aimed at facilitating earlier IIM-associated cancer detection, especially in those who are at a high risk, thus potentially improving outcomes, including survival., (© 2023. Springer Nature Limited.)- Published

- Abstract
Background: Options to reinforce or reconstruct the corpora cavernosa during penile prosthesis surgery are limited. Synthetic grafts may confer a higher infection risk. Lightweight macroporous mesh is a promising alternative due to better integration and tissue ingrowth., Aim: The study sought to report the first experience of using lightweight mesh to reinforce or reconstruct the corpora., Methods: The medical records of all patients undergoing insertion or revision of penile prosthesis between May 2016 and May 2021 were reviewed retrospectively. Patient characteristics, management, and outcomes were extracted in which mesh was used for corporal reconstruction. Poliglecaprone-25/polypropylene mesh (UltraPro) was used in all cases. The surgical technique and alternatives were summarized., Outcomes: The outcomes were infection rate, postoperative complications by Clavien-Dindo classification, and patient-reported outcomes., Results: Mesh was required during penile prosthesis surgery in 21 men (median age 56 [range, 18-74] years). Reasons for reconstruction were severe corporal fibrosis (n = 6), impending erosion (n = 6), crossover/perforation (n = 6), congenital corporal agenesis (n = 2), and excision of Peyronie's plaque. All but 2 patients (with corporal agenesis) presented for revision penile prosthesis surgery with a median number of previous revision attempts of 2 (range, 1-5). Two (10%) patients required explant after a mean follow-up of 23 ± 8.7 months. One man developed infection of the device 2 years after surgery, translating to an infection rate of 5% despite a high prevalence of diabetes (25%) in this cohort. Another required explantation due to debilitating chronic pain after 3 months. Further revision surgery for stiction syndrome was required in a third patient. Finally, another man was not satisfied with the position of the pump within the scrotum or the axial rigidity of the device, despite a second opinion suggesting no issues with the device. All men were sexually active following surgery., Clinical Implications: A lightweight mesh can be considered to reinforce or reconstruct the corpora cavernosa in complex cases in which there are no alternative techniques available., Strengths and Limitations: This is the first study using a lightweight macroporous mesh for revision penile prosthesis surgery. This was a well-characterized cohort of patients. A larger cohort with 5-year follow-up would be preferable., Conclusion: These early results suggest that a lightweight macroporous mesh may be an acceptable synthetic graft for corporal reconstruction. Poliglecaprone-25/polypropylene mesh may be ideal because it is partially absorbable, easy to handle, and not bulky., (Author(s) 2023.

- Abstract
Both TLR7 and NF-κB hyperactivity are known to contribute to pathogenesis in Systemic Lupus Erythematosus (SLE), driving a pro-interferon response, autoreactive B cell expansion and autoantibody production. UBE2L3 is an SLE susceptibility gene which drives plasmablast/plasma cell expansion in SLE, but its role in TLR7 signalling has not been elucidated. We aimed to investigate the role of UBE2L3 in TLR7-mediated NF-κB activation, and the effect of UBE2L3 inhibition by Dimethyl Fumarate (DMF) on SLE B cell differentiation in vitro. Our data demonstrate that UBE2L3 is critical for activation of NF-κB downstream of TLR7 stimulation, via interaction with LUBAC. DMF, which directly inhibits UBE2L3, significantly inhibited TLR7-induced NF-κB activation, differentiation of memory B cells and plasmablasts, and autoantibody secretion in SLE. DMF also downregulated interferon signature genes and plasma cell transcriptional programmes. These results demonstrate that UBE2L3 inhibition could potentially be used as a therapy in SLE through repurposing of DMF, thus preventing TLR7-driven autoreactive B cell maturation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

- Abstract
Objective: Idiopathic inflammatory myopathy (IIM)-associated interstitial lung disease (ILD) can range from rapidly progressive disease with high mortality to indolent disease with minimal morbidity. This systematic review and metaanalysis describe immunological, clinical, and radiographical predictors of mortality in IIM-ILD., Methods: MEDLINE and Embase database searches were completed on October 18, 2021, to identify articles providing survival data according to baseline characteristics in patients with concurrent IIM and ILD. Prognostic factors common to more than 5 papers were included in the metaanalysis using a random-effects model to report odds ratios (ORs) for binary variables and Hedges g for continuous variables. Risk of bias was assessed using the Newcastle-Ottawa Scale score and the Egger test for publication bias., Results: From 4433 articles, 62 papers were suitable for inclusion; among these studies, 38 different variables were considered. The OR for risk of death regarding the presence of anti-melanoma differentiation-associated protein 5 (MDA5) antibodies was 6.20 (95% CI 3.58-10.71), and anti-tRNA synthetase antibodies were found to be protective (OR 0.24, 95% CI 0.14-0.41). Neither antinuclear antibodies, anti-52-kDa Ro antigen antibodies, nor SSA significantly altered mortality, nor was MDA5 titer predictive. Examples of prognostic factors that are significantly associated with mortality in this study include the following: age; male sex; acute/subacute onset; clinically amyopathic dermatomyositis; dyspnea; ulceration; fever; raised C-reactive protein, ferritin, lactate dehydrogenase, alveolar to arterial O
2 (A-aO2 ) gradient, ground-glass opacity on high-resolution computed tomography (HRCT), and overall HRCT score; and reduced albumin, lymphocytes, ratio of partial pressure of oxygen in the arterial blood to fraction of inspired oxygen (PF ratio), percentage predicted transfer factor for carbon monoxide, and percentage predicted forced vital capacity. Baseline surfactant protein-D and Krebs von den Lungen-6 levels were not predictors of mortality., Conclusion: Many mortality risk factors were identified, though heterogeneity was high, with a low quality of evidence and a risk of publication bias. Studies regarding anti-MDA5 antibody-positive disease and and those from East Asia predominate, which could mask risk factors relevant to other IIM subgroups or populations., (Copyright © 2023 by the Journal of Rheumatology.)- Published

- Abstract
Objective: Hospital episode statistics (HES) are routinely recorded at every hospital admission within the National Health Service (NHS) in England. This study validates diagnostic ICD-10 codes within HES as a method of identifying cases of idiopathic inflammatory myopathies (IIMs)., Methods: All inpatient admissions at one NHS Trust between 2010 and 2020 with relevant diagnostic ICD-10 codes were extracted from HES. Hospital databases were used to identify all outpatients with IIM, and electronic care records were reviewed to confirm coding accuracy. Total hospital admissions were calculated from NHS Digital reports. The sensitivity and specificity of each code and code combinations were calculated to develop an optimal algorithm. The optimal algorithm was tested in a sample of admissions at another NHS Trust., Results: Of the 672 individuals identified by HES, 510 were confirmed to have IIM. Overall, the positive predictive value (PPV) was 76% and sensitivity 89%. Combination algorithms achieved PPVs between 89 and 94%. HES can also predict the presence of IIM-associated interstitial lung disease (ILD) with a PPV of 79% and sensitivity of 71%. The optimal algorithm excluded children (except JDM code M33.0), combined M33.0, M33.1, M33.9, M36.0, G72.4, M60.8 and M33.2, and included M60.9 only if it occurred alongside an ILD code (J84.1, J84.9 or J99.1). This produced a PPV of 88.9% and sensitivity of 84.2%. Retesting this algorithm at another NHS Trust confirmed a high PPV (94.4%)., Conclusion: IIM ICD-10 code combinations in HES have high PPVs and sensitivities. Algorithms tested in this study could be applied across all NHS Trusts to enable robust and cost-effective whole-population research into the epidemiology of IIM., (© The Author(s) 2022.

- Abstract
An important question in organogenesis is how tissue-specific transcription factors interact with signaling pathways. In some cases, transcription factors define the context for how signaling pathways elicit tissue- or cell-specific responses, and in others, they influence signaling through transcriptional regulation of signaling components or accessory factors. We previously showed that during optic vesicle patterning, the Lim-homeodomain transcription factor Lhx2 has a contextual role by linking the Sonic Hedgehog (Shh) pathway to downstream targets without regulating the pathway itself. Here, we show that during early retinal neurogenesis in mice, Lhx2 is a multilevel regulator of Shh signaling. Specifically, Lhx2 acts cell autonomously to control the expression of pathway genes required for efficient activation and maintenance of signaling in retinal progenitor cells. The Shh co-receptors Cdon and Gas1 are candidate direct targets of Lhx2 that mediate pathway activation, whereas Lhx2 directly or indirectly promotes the expression of other pathway components important for activation and sustained signaling. We also provide genetic evidence suggesting that Lhx2 has a contextual role by linking the Shh pathway to downstream targets. Through these interactions, Lhx2 establishes the competence for Shh signaling in retinal progenitors and the context for the pathway to promote early retinal neurogenesis. The temporally distinct interactions between Lhx2 and the Shh pathway in retinal development illustrate how transcription factors and signaling pathways adapt to meet stage-dependent requirements of tissue formation., Competing Interests: XL, PG, JG, AF, RR, CS, VW, SB, PL, EL No competing interests declared, (© 2022, Li et al.)

- Abstract
Background: In May 2022, the first case of monkeypox virus (MPXV) infection in the United States in the current global outbreak was identified. As part of the public health and health care facility response, a contact tracing and exposure investigation was done., Objective: To describe the contact tracing, exposure identification, risk stratification, administration of postexposure prophylaxis (PEP), and exposure period monitoring for contacts of the index patient, including evaluation of persons who developed symptoms possibly consistent with MPXV infection., Design: Contact tracing and exposure investigation., Setting: Multiple health care facilities and community settings in Massachusetts., Participants: Persons identified as contacts of the index patient., Intervention: Contact notification, risk stratification, and symptom monitoring; PEP administration in a subset of contacts., Measurements: Epidemiologic and clinical data collected through standard surveillance procedures at each facility and then aggregated and analyzed., Results: There were 37 community and 129 health care contacts identified, with 4 at high risk, 49 at intermediate risk, and 113 at low or uncertain risk. Fifteen health care contacts developed symptoms during the monitoring period. Three met criteria for MPXV testing, with negative results. Two community contacts developed symptoms. Neither met criteria for MPXV testing, and neither showed disease progression consistent with monkeypox. Among 4 persons with high-risk exposures offered PEP, 3 elected to receive PEP. Among 10 HCP with intermediate-risk exposures for which PEP was offered as part of informed clinical decision making, 2 elected to receive PEP. No transmissions were identified at the conclusion of the 21-day monitoring period, despite the delay in recognition of monkeypox in the index patient., Limitation: Descriptions of exposures are subject to recall bias, which affects risk stratification., Conclusion: In a contact tracing investigation involving 166 community and health care contacts of a patient with monkeypox, no secondary cases were identified., Primary Funding Source: None.

- Abstract
Objectives: Myalgia is a widely publicised feature of Covid-19, but severe muscle injury can occur. This systematic review summarises relevant evidence for skeletal muscle involvement in Covid-19., Methods: A systematic search of OVID and Medline databases was conducted on 16/3/2021 and updated on 28/10/2021 to identify case reports or observational studies relating to skeletal muscle manifestations of Covid-19 (PROSPERO: CRD42020198637). Data from rhabdomyolysis case reports were combined and summary descriptive statistics calculated. Data relating to other manifestations were analysed for narrative review., Results: 1920 articles were identified. From these, 61 case reports/series met inclusion criteria, covering 86 rhabdomyolysis cases. Median age of rhabdomyolysis patients was 50 years, (range 6-89). 49% had either hypertension, diabetes mellitus or obesity. 77% were male. Symptoms included myalgia (74%), fever (69%), cough (59%), dyspnoea (68%). Median peak CK was 15,783U/L. 28% required intravenous haemofiltration and 36% underwent mechanical ventilation. 62% recovered to discharge and 30% died. Dyspnoea, elevated CRP and need for intravenous haemofiltration increased risk of fatal outcome. Additional articles relating to skeletal muscular pathologies include 6 possible concomitant diagnoses or relapses of idiopathic inflammatory myopathies and 10 reports of viral-induced muscle injuries without rhabdomyolysis. Localised myositis and rhabdomyolysis with SARS-CoV-2 vaccination have been reported., Conclusions: Rhabdomyolysis is an infrequent but important complication of Covid-19. Increased mortality was associated with a high CRP, renal replacement therapy and dyspnoea. The idiopathic inflammatory myopathies (IIM) may have viral environmental triggers. However, to date the limited number of case reports do not confirm an association with Covid-19.

- Abstract
N95 respirators were reprocessed using vaporized hydrogen peroxide to supplement limited supplies during the COVID-19 pandemic. In this study, we found no statistically significant differences in qualitative and quantitative fit or filtration efficiency with reprocessing. Filtration efficiency remained above 95% even at 25 cycles of reprocessing without statistically significant change from cycle 20-25 compared to cycle 0 (P = .10, P = .05, respectively). Vaporous hydrogen peroxide is an effective option to augment N95 respirator supplies., (Copyright © 2021 Association for Professionals in Infection Control and Epidemiology, Inc.

- Abstract
Objectives: To identify clinical factors associated with cancer risk in the idiopathic inflammatory myopathies (IIMs) and to systematically review the existing evidence related to cancer screening., Methods: A systematic literature search was carried out on Medline, Embase and Scopus. Cancer risk within the IIM population (i.e. not compared with the general population) was expressed as risk ratios (RR) for binary variables and weighted mean differences (WMD) for continuous variables. Evidence relating to cancer screening practices in the IIMs were synthesized via narrative review., Results: Sixty-nine studies were included in the meta-analysis. DM subtype (RR 2.21), older age (WMD 11.19), male sex (RR 1.53), dysphagia (RR 2.09), cutaneous ulceration (RR 2.73) and anti-transcriptional intermediary factor-1 gamma positivity (RR 4.66) were identified as being associated with significantly increased risk of cancer. PM (RR 0.49) and clinically amyopathic DM (RR 0.44) subtypes, Raynaud's phenomenon (RR 0.61), interstitial lung disease (RR 0.49), very high serum creatine kinase (WMD -1189.96) or lactate dehydrogenase (WMD -336.52) levels, and anti-Jo1 (RR 0.45) or anti-EJ (RR 0.17) positivity were identified as being associated with significantly reduced risk of cancer. Nine studies relating to IIM-specific cancer screening were included. CT scanning of the thorax, abdomen and pelvis appeared to be effective in identifying underlying asymptomatic cancers., Conclusion: Cancer risk factors should be evaluated in patients with IIM for risk stratification. Screening evidence is limited but CT scanning could be useful. Prospective studies and consensus guidelines are needed to establish cancer screening strategies in IIM patients., (© The Author(s) 2021.

- Abstract
Objective: To evaluate the effects of targeting Ikaros and Aiolos by cereblon modulator iberdomide on the activation and differentiation of B-cells from patients with systemic lupus erythematosus (SLE)., Methods: CD19
+ B-cells isolated from the peripheral blood of patients with SLE (n=41) were cultured with TLR7 ligand resiquimod ±IFNα together with iberdomide or control from day 0 (n=16). Additionally, in vitro B-cell differentiation was induced by stimulation with IL-2/IL-10/IL-15/CD40L/resiquimod with iberdomide or control, given at day 0 or at day 4. At day 5, immunoglobulins were measured by ELISA and cells analysed by flow cytometry. RNA-Seq was performed on fluorescence-activated cell-sorted CD27- IgD+ naïve-B-cells and CD20low CD27+ CD38+ plasmablasts to investigate the transcriptional consequences of iberdomide., Results: Iberdomide significantly inhibited the TLR7 and IFNα-mediated production of immunoglobulins from SLE B-cells and the production of antinuclear antibodies as well as significantly reducing the number of CD27+ CD38+ plasmablasts (0.3±0.18, vehicle 1.01±0.56, p=0.011) and CD138+ plasma cells (0.12±0.06, vehicle 0.28±0.02, p=0.03). Additionally, treatment with iberdomide from day 0 significantly inhibited the differentiation of SLE B-cells into plasmablasts (6.4±13.5 vs vehicle 34.9±20.1, p=0.013) and antibody production. When given at later stages of differentiation, iberdomide did not affect the numbers of plasmablasts or the production of antibodies; however, it induced a significant modulation of gene expression involving IKZF1 and IKZF3 transcriptional programmes in both naïve B-cells and plasmablasts (400 and 461 differentially modulated genes, respectively, false discovery rate<0.05)., Conclusion: These results demonstrate the relevance of Ikaros and Aiolos as therapeutic targets in SLE due to their ability to modulate B cell activation and differentiation downstream of TLR7., Competing Interests: Competing interests: FR, MB, CP and ML received unrestricted grant support from Celgene.

- Abstract
Objectives: To estimate the incidence of cardiovascular (CV) events in idiopathic inflammatory myopathy (IIM) compared to patients with rheumatoid arthritis (RA) and the general population. To explore the contribution of traditional CV risk factors to any difference observed., Methods: A retrospective matched population-based cohort study was conducted using UK Clinical Practice Research Datalink (CPRD) from 1987 to 2013. The incidence of CV events was calculated for each cohort over time and compared using Cox proportional hazards models. Multivariable analyses were used to adjust for traditional CV risk factors., Results: A total of 603 patients with IIM 4047 RA and 4061 healthy controls were included. The rate of CV events in IIM was significantly greater than healthy controls [hazard ratio (HR) 1.47 (95% confidence interval (CI) 1.18-1.83)] and remained significant after adjustment for CV risk factors [HR 1.38 (95% CI 1.11-1.72)]. Risk was similar between IIM and RA [HR 1.01 (95% CI 0.78-1.31)]. The rate of myocardial infarction [HR 1.61 (95% CI 1.27-2.04)] but not stroke [HR 0.92 (95% CI 0.59-1.44)] was significantly greater in IIM compared to healthy controls. After the first 5 years, the rate of CV events for RA remained significantly greater compared to the control group, but appeared to return to that of the healthy controls in the IIM group., Conclusion: IIM is associated with an increased risk of CV events in the first 5 years after diagnosis similar to that of RA. Beyond 5 years, the risk appears to return to that of the general population in IIM but not RA. Key Points • The excess risk of cardiovascular events in IIM is similar to that found in RA. • The excess risk of cardiovascular events is greatest in the first 5 years after diagnosis.

- Abstract
Objectives: To evaluate the distribution of radiological characteristics stratified by different myositis-specific autoantibodies, identify prognostic value of high-resolution CT (HRCT) patterns in DM-associated interstitial lung disease (DM-ILD), and explore the possible mechanism associated with macrophage activation., Methods: We enrolled 165 patients with PM/DM-ILD. The distribution of HRCT radiological types with different myositis-specific autoantibodies and the relationship between radiological features and ILD course and prognosis were analysed. Additionally, the potential role of macrophage activation in rapidly progressive ILD (RP-ILD) with DM was studied., Results: The organizing pneumonia pattern was dominant in HRCT findings of patients with DM-ILD, especially those with anti-SAE (6/6, 100%) and anti-MDA5 (46/62, 74.2%) antibodies. The ratios of organizing pneumonia and nonspecific interstitial pneumonia patterns were almost equal in patients with aminoacyl tRNA synthetase antibodies, and nonspecific interstitial pneumonia pattern was associated with a mild clinical course. Lower lung zone consolidation in HRCT was related to RP-ILD in both anti-MDA5 and anti-aminoacyl tRNA synthetase antibody-positive groups. Ferritin levels of >1000 ng/ml (odds ratio (OR), 12.3; P=0.009), elevated carcinoembryonic antigen (OR, 5.8; P=0.046) and carbohydrate antigen 19-9 (OR, 7.8; P=0.018) were independent predictors of a lower lung zone consolidation pattern in anti-MDA5 antibody-positive DM. The infiltration of CD163-positive macrophages into alveolar spaces was significantly higher in the DM-RP-ILD group than in the chronic DM-ILD group., Conclusion: HRCT patterns are different among variable myositis-specific autoantibodies positive patients with ILD and lower zone consolidation in HRCT correlated with RP-ILD in DM. Activated macrophages may contribute to the pathogenesis of RP-ILD in DM., (© The Author(s) 2020. Published by Oxford University Press on behalf of the British Society for Rheumatology.

- Abstract
The formation of specific protein-protein interactions is often a key to a protein's function. During complex formation, each protein component will undergo a change in the conformational state, for some these changes are relatively small and reside primarily at the sidechain level; however, others may display notable backbone adjustments. One of the classic problems in the protein-docking field is to be able to a priori predict the extent of such conformational changes. In this work, we investigated three protocols to find the most suitable input structure conformations for cross-docking, including a robust sampling approach in normal mode space. Counterintuitively, knowledge of the theoretically best combination of normal modes for unbound-bound transitions does not always lead to the best results. We used a novel spatial partitioning library, Aether Engine (see Supplementary Materials), to efficiently search the conformational states of 56 receptor/ligand pairs, including a recent CAPRI target, in a systematic manner and selected diverse conformations as input to our automated docking server, SwarmDock, a server that allows moderate conformational adjustments during the docking process. In essence, here we present a dynamic cross-docking protocol, which when benchmarked against the simpler approach of just docking the unbound components shows a 10% uplift in the quality of the top docking pose., (© 2019 The Authors.

- Abstract
Objectives: It has been over 10 years since the first report of autoantibodies directed against phenylalanyl tRNA synthetase (anti-Zo) in a patient with features of the anti-synthetase syndrome. In that time no further cases have been published. Here we aim to characterize more fully the clinical phenotype of anti-Zo-associated myositis by describing the clinical features of nine patients., Methods: Anti-Zo was identified by protein-immunoprecipitation in patients referred for extended spectrum myositis autoantibody testing at our laboratory. Results were confirmed by immunodepletion using a reference serum. Medical records were retrospectively reviewed to provide detailed information of the associated clinical phenotype for all identified patients. Where possible, HLA genotype was imputed using Illumina protocols., Results: Nine patients with anti-Zo were identified. The median age at disease onset was 51 years, and six patients were female. Seven patients had evidence of inflammatory muscle disease, seven of interstitial lung disease and six of arthritis. The reported pattern of interstitial lung disease varied with usual interstitial pneumonia, non-specific interstitial pneumonia and organizing pneumonia all described. Other features of the anti-synthetase syndrome such as RP and mechanics hands were common. HLA data was available for three patients, all of whom had at least one copy of the HLA 8.1 ancestral haplotype., Conclusion: Patients with anti-Zo presenting with features of the anti-synthetase syndrome and interstitial lung disease is a common finding. Like other myositis autoantibodies, there is likely to be a genetic association with the HLA 8.1 ancestral haplotype., (© The Author(s) 2019.

- Abstract
Context: Non-visible haematuria (NVH) is a common finding and may indicate undiagnosed urological cancer. The optimal investigation of NVH is unclear, given the incidence of cancer and the public health implications of testing all individuals with this finding., Objective: We review contemporary literature to determine the association of NVH with the diagnosis of bladder cancer (BC), upper tract urothelial carcinoma (UTUC), and kidney cancer (KC)., Evidence Acquisition: A systematic review of original articles in English was completed in May 2019. Meta-analyses for the diagnostic accuracy of NVH and urine cytology were performed., Evidence Synthesis: We screened 1529 articles and selected 78 manuscripts that fulfilled our inclusion criteria for narrative synthesis. Forty manuscripts were eligible for a meta-analysis (reporting 19 193 persons). The likelihood of a urological cancer in patients with NVH increased with age (<1% in those aged <40yr), male sex, and cigarette smoking. Less than 1% of patients are found to have a urological cancer after a negative NVH evaluation. Cancer detection rates in individuals evaluated for NVH ranged from 0% to 16% for BC in 37 studies, 0% to 3.5% for UTUC in 30 studies, and 0% to 9.7% for KC in 29 studies. Substantial statistical heterogeneity was present for the meta-analysis of detection rates., Conclusions: We present an up-to-date review of the association of NVH with the diagnosis of BC, UTUC, and KC. Individuals with dipstick positive haematuria aged ≥40yr, who have had potential precipitating causes excluded, should undergo an evaluation. Re-evaluation of patients with unremarkable initial investigations should be performed in high-risk patients or if new symptoms occur., Patient Summary: One in five people have microscopic traces of blood in their urine. This is an important indicator of urological cancer. Investigating all patients is uncomfortable and expensive. We evaluate the risk of cancer and estimate risks to groups of individuals., (Copyright © 2019 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

- Abstract
The measurement of online sentiment is a developing field in social science and big data research. The methodology from this study provides an analysis of online sentiment using a unique combination of NLP and human validation techniques in order to create net sentiment scores and categorise topics of online conversation. The study focused on measuring the online sentiment of South Africa's major banks (covering almost the entire retail banking industry) over a 12-month period. Through this methodology, firms are able to track shifts in online sentiment (including extreme firestorms) as well as to monitor relevant conversation topics. To date, no published methodology combines the use of big data NLP and human validation in such a structured way.• Microsampling for manual validation of sentiment analysis (both qualitative and quantitative approaches in order to obtain the most accurate results) • Sentiment measurement • Sentiment map ., (© 2020 The Author(s).)

- Abstract
Background: Guidelines advocate early re-resection for these cancers, although the benefits are unclear and the uniform need is questioned. Here, we compare the outcomes using a large single-center cohort., Objectives: To compare the outcomes of patients with high-grade non-muscle-invasive bladder cancer (BC) who underwent and who did not undergo re-resection following their initial treatment., Design, Setting, and Participants: We identified all eligible patients with a new diagnosis treated between 1994 and 2009 in Sheffield. We annotated these with hospital and registry records., Outcome Measurements and Statistical Analysis: Primary outcomes were disease-specific and overall survival. Secondary outcomes were the findings at re-resection, rates of muscle invasion, and radical treatment. Statistical tests were two tailed and significance defined as p<0.05., Results and Limitations: We identified 932 eligible patients, including 229(25%) who underwent re-resection within 12 wk and 234 (25%) within 3-6 mo after diagnosis. Clinicopathological criteria were similar in patients with and without re-resection. Histological findings on re-resection were no residual cancer in 91 (20%) and BC in 138 (30%: 15 low-grade and 85 high-grade non-muscle-invasive cancers, and 38 muscle-invasive cancers). Patients with re-resection were more frequently diagnosed with muscle invasion (126 [27%] vs 49 [11%], chi-square p<0.001) and more commonly underwent radical treatment (127 [27%] vs 35 [8%], p<0.001) than those without re-resection. A total of 207 patients died from BC, including 46 (22%) with and 161 (78%) without re-resection. Patients who underwent re-resection within 3 mo had significantly higher disease-specific (log rank p=0.009) and overall survival (p<0.001) survival compared with those who did not. Differences were present only for patients with pT1 cancer at diagnosis., Conclusions: Patients undergoing re-resection within 3 mo of diagnosis were more likely to have histologically identified muscle invasion, were more likely to undergo radical treatment, and had a higher survival rate. The differences were greatest in patients with lamina propria invasion, suggesting the potential to avoid in others. Limitations of our work include retrospective design and selection bias., Patient Summary: Patients undergoing re-resection after a diagnosis of high-grade non-muscle-invasive bladder cancer had higher disease-specific and overall survival rates due to more accurate diagnosis and appropriate subsequent radical treatment. Re-resection carries greatest benefit to patients with lamina propria invasion at diagnosis., (Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.)

- Abstract
Financially supporting and sustaining behavioral health services integrated into primary care settings remains a major barrier to widespread implementation. Sustaining Healthcare Across Integrated Primary Care Efforts (SHAPE) was a demonstration project designed to prospectively examine the cost savings associated with utilizing an alternative payment methodology to support behavioral health services in primary care practices with integrated behavioral health services. Six primary care practices in Colorado participated in this project. Each practice had at least one on-site behavioral health clinician providing integrated behavioral health services. Three practices received non-fee-for-service payments (i.e., SHAPE payment) to support provision of behavioral health services for 18 months. Three practices did not receive the SHAPE payment and served as control practices for comparison purposes. Assignment to condition was nonrandom. Patient claims data were collected for 9 months before the start of the SHAPE demonstration project (pre-period) and for 18 months during the SHAPE project (post-period) to evaluate cost savings. During the 18-month post-period, analysis of the practices' claims data demonstrated that practices receiving the SHAPE payment generated approximately $1.08 million in net cost savings for their public payer population (i.e., Medicare, Medicaid, and Dual Eligible; N = 9,042). The cost savings were primarily achieved through reduction in downstream utilization (e.g., hospitalizations). The SHAPE demonstration project found that non-fee-for-service payments for behavioral health integrated into primary care may be associated with significant cost savings for public payers, which could have implications on future delivery and payment work in public programs (e.g., Medicaid)., (© Society of Behavioral Medicine 2018.

- Abstract
Objectives: To study the effects of abatacept on disease activity and on muscle biopsy features of adult patients with dermatomyositis (DM) or polymyositis (PM)., Methods: Twenty patients with DM (n=9) or PM (n=11) with refractory disease were enrolled in a randomised treatment delayed-start trial to receive either immediate active treatment with intravenous abatacept or a 3 month delayed-start. The primary endpoint was number of responders, defined by the International Myositis Assessment and Clinical Studies Group definition of improvement (DOI), after 6 months of treatment. Secondary endpoints included number of responders in the early treatment arm compared with the delayed treatment arm at 3 months. Repeated muscle biopsies were investigated for cellular markers and cytokines., Results: 8/19 patients included in the analyses achieved the DOI at 6 months. At 3 months of study, five (50%) patients were responders after active treatment but only one (11%) patient in the delayed treatment arm. Eight adverse events (AEs) were regarded as related to the drug, four mild and four moderate, and three serious AEs, none related to the drug. There was a significant increase in regulatory T cells (Tregs), whereas other markers were unchanged in repeated muscle biopsies., Conclusions: In this pilot study, treatment of patients with DM and PM with abatacept resulted in lower disease activity in nearly half of the patients. In patients with repeat muscle biopsies, an increased frequency of Foxp3
+ Tregs suggests a positive effect of treatment in muscle tissue., Competing Interests: Competing interests: IEL: research grant and advisory board consultant for BMS, research grant from AstraZeneca, consultant for MedImmune, aTyr and IDERA.

- Abstract
Objective: To develop and validate new classification criteria for adult and juvenile idiopathic inflammatory myopathies (IIM) and their major subgroups., Methods: Candidate variables were assembled from published criteria and expert opinion using consensus methodology. Data were collected from 47 rheumatology, dermatology, neurology, and pediatric clinics worldwide. Several statistical methods were utilized to derive the classification criteria., Results: Based on data from 976 IIM patients (74% adults; 26% children) and 624 non-IIM patients with mimicking conditions (82% adults; 18% children), new criteria were derived. Each item is assigned a weighted score. The total score corresponds to a probability of having IIM. Subclassification is performed using a classification tree. A probability cutoff of 55%, corresponding to a score of 5.5 (6.7 with muscle biopsy) "probable IIM," had best sensitivity/specificity (87%/82% without biopsies, 93%/88% with biopsies) and is recommended as a minimum to classify a patient as having IIM. A probability of ≥90%, corresponding to a score of ≥7.5 (≥8.7 with muscle biopsy), corresponds to "definite IIM." A probability of <50%, corresponding to a score of <5.3 (<6.5 with muscle biopsy), rules out IIM, leaving a probability of ≥50-<55% as "possible IIM.", Conclusion: The European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for IIM have been endorsed by international rheumatology, dermatology, neurology, and pediatric groups. They employ easily accessible and operationally defined elements, and have been partially validated. They allow classification of "definite," "probable," and "possible" IIM, in addition to the major subgroups of IIM, including juvenile IIM. They generally perform better than existing criteria., (© 2017, American College of Rheumatology.)

- Abstract
Background: The idiopathic inflammatory myopathies (IIM, myositis) are a heterogeneous group of chronic autoimmune disorders causing considerable physical and mental health impact. There is a lack of formalised guidance defining best practice for the management of myositis, contributing to inconsistent care provision and some patients feeling isolated and unsupported.To address these issues, we evaluated the clinical services available to adults with myositis in the UK. We then created patient-centred standards of care using a structured process involving patients, their relatives and caregivers, physicians and allied healthcare professionals., Methods: After an initial focus group, the clinical services available to patients with myositis were evaluated using a patient-completed questionnaire. Draft standards of care were created, each addressing deficits in care provision identified by patients. In response to feedback, including a two-stage modified Delphi exercise, these draft standards were iteratively improved until consensus was reached. Accompanying plain language versions of the standards of care and an audit tool were also created., Results: We identified issues regarding diagnostic pathways, access to specialist services, advice and support regarding employment, medication-related adverse events and the treatment of extra-muscular manifestations. Fifteen standards of care were drafted. After modification, agreement was reached on eleven final standards of care., Conclusion: These patient-centred standards of care for adults with myositis provide a benchmark for the evaluation of local practice. Their implementation will promote consistent good practice across care providers and empower patients when seeking access to local services., Competing Interests: We invited members of the charity group Myositis UK to complete a service evaluation questionnaire and in some cases also participate in the Delphi panel and focus group to produce plain-language versions of the standards of care. We used the Health Research Authority (HRA) decision tools (http://www.hra-decisiontools.org.uk/) to determine that our project was not research and that research ethics approval was not required. Participants were not randomised to different groups, no changes to treatment or any other standard clinical care procedures were made or recommended, and the findings were not generalisable (i.e. outcomes are only of interest to the specific clinical area considered). Specific consent for participation was therefore not obtained.Not applicable.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

- Abstract
Objective: To describe the methodology used to develop new classification criteria for adult and juvenile idiopathic inflammatory myopathies (IIMs) and their major subgroups., Methods: An international, multidisciplinary group of myositis experts produced a set of 93 potentially relevant variables to be tested for inclusion in the criteria. Rheumatology, dermatology, neurology and paediatric clinics worldwide collected data on 976 IIM cases (74% adults, 26% children) and 624 non-IIM comparator cases with mimicking conditions (82% adults, 18% children). The participating clinicians classified each case as IIM or non-IIM. Generally, the classification of any given patient was based on few variables, leaving remaining variables unmeasured. We investigated the strength of the association between all variables and between these and the disease status as determined by the physician. We considered three approaches: (1) a probability-score approach, (2) a sum-of-items approach criteria and (3) a classification-tree approach., Results: The approaches yielded several candidate models that were scrutinised with respect to statistical performance and clinical relevance. The probability-score approach showed superior statistical performance and clinical practicability and was therefore preferred over the others. We developed a classification tree for subclassification of patients with IIM. A calculator for electronic devices, such as computers and smartphones, facilitates the use of the European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria., Conclusions: The new EULAR/ACR classification criteria provide a patient's probability of having IIM for use in clinical and research settings. The probability is based on a score obtained by summing the weights associated with a set of criteria items., Competing Interests: Competing interests: JAS has received research grants from Takeda and Savient and consultant fees from Savient, Takeda, Regeneron, Merz, Bioiberica, Crealta and Allergan.

- Abstract
Haemolytic anaemia caused by a paravalvular leak presenting as progressively worsening red urine. Haemoglobinuria was easily mistaken for gross haematuria, resulting in extensive invasive urological investigation that proved to be futile. Further investigation following an emergency admission led to the realisation that intravascular haemolysis secondary to a paravalvular leakâ€"presenting 43 years following metallic valve insertionâ€"was the cause of discoloured urine and newly presenting symptomatic anaemia. This case highlights that there remains other causes of what often appears to be haematuria, and further exploration of alternative causes should be considered when no urological cause is found., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

- Abstract
Several uncontrolled studies have encouraged the use of rituximab (RTX) in patients with myositis. Unfortunately, the first placebo-phase trial to assess the efficacy of RTX in refractory myositis did not show a significant difference between the two treatment groups, and doubts have been expressed about its study design. In this review we present an up-to-date overview of the reported experiences of RTX therapy in myositis. A PubMed search was performed to find all the available cases of refractory myositis patients treated with RTX up to July 2015. The following terms were assessed: inflammatory myopathies OR anti-synthetase syndrome OR polymyositis OR dermatomyositis AND RTX. A total of 48 studies were included. We identified 458 patients with myositis treated with RTX. We found a rate of response to RTX of 78.3%. RTX can play a role in the management of patients with myositis, at least in those with positive myositis-specific autoantibodies., (© The Author 2016.

- Abstract
The patient-centered medical home (PCMH) is a promising framework for the redesign of primary care and more recently specialty care. As defined by the Agency for Healthcare Research and Quality, the PCMH framework has 5 attributes: comprehensive care, patient-centered care, coordinated care, accessible services, and quality and safety. Evidence increasingly demonstrates that for the PCMH to best achieve the Triple Aim (improved outcomes, decreased cost, and enhanced patient experience), treatment for behavioral health (including mental health, substance use, and life stressors) must be integrated as a central tenet. However, challenges to implementing the PCMH framework are compounded for real-world practitioners because payment reform rarely happens concurrently. Nowhere is this more evident than in attempts to integrate behavioral health clinicians into primary care. As behavioral health clinicians find opportunities to work in integrated settings, a comprehensive understanding of payment models is integral to the dialogue. This article describes alternatives to the traditional fee for service (FFS) model, including modified FFS, pay for performance, bundled payments, and global payments (i.e., capitation). We suggest that global payment structures provide the best fit to enable and sustain integrated behavioral health clinicians in ways that align with the Triple Aim. Finally, we present recommendations that offer specific, actionable steps to achieve payment reform, complement PCMH, and support integration efforts through policy.

- Abstract
This case study evaluates and tracks vitality of a city (Seattle), based on a data-driven approach, using strategic, robust, and sustainable metrics. This case study was collaboratively conducted by the Downtown Seattle Association (DSA) and CDO Analytics teams. The DSA is a nonprofit organization focused on making the city of Seattle and its Downtown a healthy and vibrant place to Live, Work, Shop, and Play. DSA primarily operates through public policy advocacy, community and business development, and marketing. In 2010, the organization turned to CDO Analytics ( cdoanalytics.org ) to develop a process that can guide and strategically focus DSA efforts and resources for maximal benefit to the city of Seattle and its Downtown. CDO Analytics was asked to develop clear, easily understood, and robust metrics for a baseline evaluation of the health of the city, as well as for ongoing monitoring and comparisons of the vitality, sustainability, and growth. The DSA and CDO Analytics teams strategized on how to effectively assess and track the vitality of Seattle and its Downtown. The two teams filtered a variety of data sources, and evaluated the veracity of multiple diverse metrics. This iterative process resulted in the development of a small number of strategic, simple, reliable, and sustainable metrics across four pillars of activity: Live, Work, Shop, and Play. Data during the 5 years before 2010 were used for the development of the metrics and model and its training, and data during the 5 years from 2010 and on were used for testing and validation. This work enabled DSA to routinely track these strategic metrics, use them to monitor the vitality of Downtown Seattle, prioritize improvements, and identify new value-added programs. As a result, the four-pillar approach became an integral part of the data-driven decision-making and execution of the Seattle community's improvement activities. The approach described in this case study is actionable, robust, inexpensive, and easy to adopt and sustain. It can be applied to cities, districts, counties, regions, states, or countries, enabling cross-comparisons and improvements of vitality, sustainability, and growth.

- Abstract
Background: To determine whether optimal use of serial measurements of serum levels of soluble cell adhesion molecules (CAM) can improve monitoring of disease activity in SLE., Methods: Serum levels of soluble CAM and conventional SLE biomarkers were measured in serial samples (n = 80) from 21 SLE patients during and after flare and correlated in longitudinal analysis with disease activity determined by ECLAM score. Blood samples from a second cohort of 34 SLE patients were subject to flow cytometry to correlate serum biomarkers with B cell subsets., Results: By adjusting for the baseline level (at the first visit), delta soluble vascular cell adhesion molecule-1 (sVCAM-1) showed stronger correlation with changes in ECLAM score and improved sensitivity and specificity for identifying SLE responders versus non-responders compared to conventional SLE biomarkers including anti-dsDNA antibody titre and complement C3. Multiple regression analysis identified delta sVCAM-1 as the best marker of SLE clinical response. sVCAM-1 levels were significantly correlated with CD95(+)CD27(+) activated memory B cells, CD95(+) plasmablasts and circulating plasma cell numbers in SLE patients., Conclusion: Subtracting a baseline level of sVCAM-1 for each individual substantially improved its utility as a biomarker. Delta sVCAM-1 was superior to conventional SLE biomarkers for monitoring changes in disease activity. This suggests that serial monitoring of serum sVCAM-1 trends should be considered in SLE patients to document responses to treatment. We hypothesise that the correlation between activated B cell subsets and circulating plasma cell numbers with soluble VCAM-1 serum levels in SLE may relate to the important role of VCAM-1 in B lymphocyte survival and maturation in bone marrow and secondary lymphoid tissues.

- Abstract
Objective: Currently there are no evidence-based recommendations regarding fitness and strength tests for patients with childhood or adult idiopathic inflammatory myopathies (IIM). This hinders clinicians and researchers in choosing the appropriate fitness- or muscle strength-related outcome measures for these patients. Through a Delphi survey, we aimed to identify a candidate core set of fitness and strength tests for children and adults with IIM., Methods: Fifteen experts participated in a Delphi survey that consisted of 5 stages to achieve a consensus. Using an extensive search of published literature and through the work of experts, a candidate core set based on expert opinion and clinimetrics properties was developed. Members of the International Myositis Assessment and Clinical Studies Group were invited to review this candidate core set during the final stage, which led to a final candidate core set., Results: A core set of fitness- and strength-related outcome measures was identified for children and adults with IIM. For both children and adults, different tests were identified and selected for maximal aerobic fitness, submaximal aerobic fitness, anaerobic fitness, muscle strength tests, and muscle function tests., Conclusion: The core set of fitness- and strength-related outcome measures provided by this expert consensus process will assist practitioners and researchers in deciding which tests to use in patients with IIM. This will improve the uniformity of fitness and strength tests across studies, thereby facilitating the comparison of study results and therapeutic exercise program outcomes among patients with IIM.

- Abstract
Previous reports indicate that caloric restriction attenuates anxiety and other behavioral responses to acute stress, and blunts the ability of stress to increase anterior pituitary release of adrenocorticotropic hormone. Since hindbrain glucagon-like peptide-1 (GLP-1) neurons and noradrenergic prolactin-releasing peptide (PrRP) neurons participate in behavioral and endocrine stress responses, and are sensitive to the metabolic state, we examined whether overnight food deprivation blunts stress-induced recruitment of these neurons and their downstream hypothalamic and limbic forebrain targets. A single overnight fast reduced anxiety-like behavior assessed in the elevated-plus maze and acoustic startle test, including marked attenuation of light-enhanced startle. Acute stress [i.e., 30 min restraint (RES) or 5 min elevated platform exposure] robustly activated c-Fos in GLP-1 and PrRP neurons in fed rats, but not in fasted rats. Fasting also significantly blunted the ability of acute stress to activate c-Fos expression within the anterior ventrolateral bed nucleus of the stria terminalis (vlBST). Acute RES stress suppressed dark-onset food intake in rats that were fed ad libitum, whereas central infusion of a GLP-1 receptor antagonist blocked RES-induced hypophagia, and reduced the ability of RES to activate PrRP and anterior vlBST neurons in ad libitum-fed rats. Thus, an overnight fast "silences" GLP-1 and PrRP neurons, and reduces both anxiety-like and hypophagic responses to acute stress. The partial mimicking of these fasting-induced effects in ad libitum-fed rats after GLP-1 receptor antagonism suggests a potential mechanism by which short-term negative energy balance attenuates neuroendocrine and behavioral responses to acute stress., Significance Statement: The results from this study reveal a potential central mechanism for the "metabolic tuning" of stress responsiveness. A single overnight fast, which markedly reduces anxiety-like behavior in rats, reduces or blocks the ability of acute stress to activate hindbrain neurons that are immunoreactive for either prolactin-releasing peptide or glucagon-like peptide 1, and attenuates the activation of their stress-sensitive projection targets in the limbic forebrain. In nonfasted rats, central antagonism of glucagon-like peptide 1 receptors partially mimics the effect of an overnight fast by blocking the ability of acute stress to inhibit food intake, and by attenuating stress-induced activation of hindbrain and limbic forebrain neurons. We propose that caloric restriction attenuates behavioral and physiological responses to acute stress by "silencing" central glucagon-like peptide 1 signaling pathways., (Copyright © 2015 the authors 0270-6474/15/3510701-14$15.00/0.)
