Axial Spondyloarthritis: Does Magnetic Resonance Imaging Classification Improve Report Interpretation.

OBJECTIVE: The interpretation of magnetic resonance imaging (MRI) reports is crucial for the diagnosis of axial spondyloarthritis, but the subjective nature of narrative reports can lead to varying interpretations. This study presents a validation of a novel MRI reporting system for the sacroiliac joint in clinical practice. METHODS: A historical review was conducted on 130 consecutive patients referred by 2 rheumatologists for initial MRI assessment of possible axial spondyloarthritis. The original MRI reports were interpreted by the rheumatologists and the radiologist who originally read the images and then categorized according to the novel system. Two musculoskeletal radiologists then reinterpreted the original MRI scans using the new system, and the resulting reports were interpreted and categorized by the same rheumatologists. The quality of the new framework was assessed by comparing the interpretations of both reports. RESULTS: Ninety-two patients met the study criteria. The rheumatologists disagreed on the categorization of the original MRI reports in 12% of cases. The rheumatologists and original radiologists disagreed on the categorization of the initial report in 23.4% of cases. In contrast, there was 100% agreement between the rheumatologists and radiologists on the categorization of the new MRI report. CONCLUSION: The new MRI categorization system significantly improved the agreement between the clinician and radiologist in report interpretation. The system provided a standard vocabulary for reporting, reduced variability in report interpretation, and may therefore improve clinical decision-making.

Clinical Characteristics of Adolescents With Juvenile Idiopathic Arthritis Transitioning to Adult Rheumatology Care in Canada: Results From the CAPRI Registry.

OBJECTIVE: Using Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) juvenile idiopathic arthritis (JIA) registry data, we describe (1) clinical characteristics of patients with JIA transitioning to adult care, (2) prevalence of disease-related damage and complications, and (3) changes in disease activity during the final year prior to transfer. METHODS: Registry participants who turned 17 years between February 2017 and November 2021 were included. Clinical characteristics and patient-reported outcomes (PROs) at the last recorded pediatric rheumatology visit, and changes observed in the year prior to that visit were analyzed. Physicians completed an additional questionnaire characterizing cumulative disease-related damage and adverse events by age 17 years. RESULTS: At their last visit, 88 of 131 participants (67%) had inactive and 42 (32%) had active disease. Overall, 96 (73%) were on medications and 41 (31%) were on biologic disease-modifying antirheumatic drugs. Among 80 participants for whom the additional questionnaire was completed, 26% had clinically detected joint damage, 31% had joint damage on imaging, 14% had uveitis, and 7.5% had experienced at least 1 serious adverse event. During the final year, 44.2% of patients were in remission, 28.4% attained inactive disease, and 27.4% became or remained active. Mean scores of PROs were stable overall during that last year, but a minority reported marked worsening. CONCLUSION: A substantial proportion of youth with JIA transitioning to adult care in Canada had a high disease burden, which was reflected by their degree of disease activity, joint damage, or ongoing medication use. These results will inform pediatric and adult providers of anticipated needs during transition of care.

Mind the Gap: A Longitudinal Analysis of the Experiences of Adolescents and Parents in a Rheumatology Transition Clinic.

BACKGROUND: The transition from pediatric to adult care is a critical time when adolescent patients and their families face many challenges. This period can be associated with an increase in disease-related morbidity and mortality. The aim of our study is to identify gaps in transition-related care to help guide areas for improvement. METHODS: Patients (14-19 years) with juvenile idiopathic arthritis or systemic lupus erythematosus and one of their parents were recruited from the McMaster Rheumatology Transition Clinic. Both were asked to complete the Mind the Gap questionnaire, a validated tool to assess experience and satisfaction with transition care in a clinic setting. The questionnaire, addressing 3 important domains of care: management of the environment, provider characteristics, and process issues, was completed twice-once based on their current clinical experience and again based on their ideal clinical encounter. Positive scores suggest current care is less than ideal; negative scores suggest current care exceeds the ideal experience. RESULTS: Most patients (n = 65, 68% female) had a diagnosis of juvenile idiopathic arthritis (87%). Patients identified mean gap scores between 0.2 and 0.3 for each domain of Mind the Gap, with female patients having higher gap scores compared with male patients. Parents (n = 51) identified gap scores between 0.0 and 0.3. Patients identified process issues as having the largest gap, whereas parents identified management of the environment as having the largest gap. CONCLUSIONS: We identified several gaps in transition clinic care relative to what patients and parents identify as ideal. These can be used to improve the rheumatology transition care that is currently being provided.

A survey of Canadian adult rheumatologists' knowledge, comfort level, and barriers in assessing psychosocial needs of young adults with rheumatic diseases.

To assess adult rheumatologists' comfort level, current practices, and barriers to provision of optimal care in supporting young adults with pediatric-onset rheumatic conditions in Canada. Survey questions were informed by literature review, a needs assessment, and using milestones listed by the Royal College of Physicians and Surgeons of Canada for the entrustable professional activities (EPAs) applicable to care for rheumatology patients transitioning to adult practice. The electronic survey was distributed to adult rheumatology members of the Canadian Rheumatology Association over 4 months. Four hundred and fifty-one rheumatologists received the survey, with a response rate of 15.2%. Most respondents were from Ontario and had been in practice ≥ 10 years. Three quarters reported a lack of training in transition care although the same proportion were interested in learning more about the same. Approximately 40% felt comfortable discussing psychosocial concerns such as gender identity, sexuality, contraception, drug and alcohol use, vaping, and mental health. Despite this, 45-50% reported not discussing vaping or gender identity at all. The most frequently reported barriers to providing transition care were lack of primary care providers, allied health support, and training in caring for this age group. Most adult rheumatologists lack formal training in transition care and view it as a barrier to providing care for this unique patient population. Future educational initiatives for adult rheumatology trainees should include issues pertaining to adolescents and young adults. More research is needed to assess the effectiveness of resources such as transition navigators in ensuring a successful transition process.

Effect of pregnancy on scleroderma progression.

Objective: To explore the trajectory of scleroderma disease activity in women who experienced a pregnancy after systemic sclerosis diagnosis compared to nulliparous women. Methods: We analyzed data from the Canadian Scleroderma Research Group registry by identifying nulliparous women and women with ⩾1 pregnancy after systemic sclerosis diagnosis. Patient characteristics were compared between groups at registry entry. Controlling for age, smoking, and time since systemic sclerosis diagnosis, generalized estimating equations tested the effect of pregnancy on force vital capacity, diffusing capacity of the lungs for carbon monoxide, right ventricular systolic pressure, glomerular filtration rate, antibody status, active digital ulcers, physician global assessment of activity, and severity over 9 years. Results: At registry entry, numbers of women in the nulliparous and pregnancy after systemic sclerosis diagnosis groups were 153 and 45, respectively. Corresponding numbers at 6 and 9 years were 48 and 21, and 18 and 9, respectively. The prevalence of anti-topoisomerase positivity was 18.3% in nulliparous and 12.5% in pregnancy after systemic sclerosis diagnosis. Baseline differences included mean (Standard deviation) age of diagnosis (nulliparous: 38.8 (14.0), pregnancy after systemic sclerosis diagnosis: 22.6 (6.8) years, p < 0.001), disease duration (nulliparous: 9.6 (8.9), pregnancy after systemic sclerosis diagnosis: 21.9 (9.6) years; p < 0.001), and inflammatory arthritis (nulliparous: 41 (28%), pregnancy after systemic sclerosis diagnosis: 22 (49%), p = 0.009). There were no significant differences between groups in the change of any outcomes over time. Conclusion: Results demonstrated that having ⩾1 pregnancy after systemic sclerosis diagnosis did not appear to significantly impact long-term renal, respiratory, or global function outcomes. While this offers a hopeful message to systemic sclerosis patients planning a pregnancy, physicians and patients should remain vigilant for potential post-partum complications.

Self-Reported Transition Readiness of Adolescent Patients with Rheumatic Disease: Do the Parents Agree?

Our objective was to compare transition readiness assessment scores from adolescents with rheumatic disease with their parents and analyze their level of agreement. We found that adolescents and parents generally agree on the level of the transition readiness; however, there is occasional disagreement in specific domains.

Intravenous ketorolac versus morphine in children presenting with suspected appendicitis: a pilot single-centre non-inferiority randomised controlled trial.

OBJECTIVES: Despite a lack of evidence demonstrating superiority to non-steroidal anti-inflammatory drugs, like ketorolac, that are associated with lower risk of harms, opioids remain the most prescribed analgesic for acute abdominal pain. In this pilot trial, we will assess the feasibility of a definitive trial comparing ketorolac with morphine in children with suspected appendicitis. We hypothesise that our study will be feasible based on a 40% consent rate. METHODS AND ANALYSIS: A single-centre, non-inferiority, blinded (participant, clinician, investigators and outcome assessors), double-dummy randomised controlled trial of children aged 6-17 years presenting to a paediatric emergency department with ≤5 days of moderate to severe abdominal pain (≥5 on a Verbal Numerical Rating Scale) and are investigated for appendicitis. We will use variable randomised blocks of 4-6 and allocate participants in 1:1 ratio to receive either intravenous (IV) ketorolac 0.5 mg/kg+IV morphine placebo or IV morphine 0.1 mg/kg+IV ketorolac placebo. Analgesic co-intervention will be limited to acetaminophen (commonly used as first-line therapy). Participants in both groups will be allowed rescue therapy (morphine 0.5 mg/kg) within 60 min of our intervention. Our primary feasibility outcome is the proportion of eligible patients approached who provide informed consent and are enrolled in our trial. Our threshold for feasibility will be to achieve a ≥40% consent rate, and we will enrol 100 participants into our pilot trial. ETHICS AND DISSEMINATION: Our study has received full approval by the Hamilton integrated Research Ethics Board. We will disseminate our study findings at national and international paediatric research conferences to garner interest and engage sites for a future multicentre definitive trial. TRIAL REGISTRATION: NCT04528563, Pre-results.

Infliximab therapy in refractory sarcoidosis: a multicenter real-world analysis.

BACKGROUND: Infliximab is a monoclonal antibody that binds and neutralizes circulating tumor necrosis factor-alpha, a key inflammatory cytokine in the pathophysiology of sarcoidosis. Despite the paucity of randomized clinical trials, infliximab is often considered a therapeutic option for refractory disease. Our study aimed to investigate the effectiveness of infliximab in patients with refractory sarcoidosis. METHODS: Sarcoidosis patients from three tertiary centres were retrospectively identified by pharmacy records based on treatment with infliximab. Treatment with Infliximab was initiated in patients who failed first and second line immunomodulators as determined by a multidisciplinary team of Respirologists, Dermatologists, ENT specialists, Rheumatologists, and Neurologists. Participants were characterized by the primary organ for which infliximab was initiated and the total number of organs involved. Clinical outcomes were categorized as treatment success versus failure. We defined treatment success as (A) improvement of cutaneous, upper airway, lymph node, gastrointestinal, eye, or joint manifestations; or (B) improvement or no change in central nervous system (CNS) or pulmonary manifestations. RESULTS: 33 patients with refractory sarcoidosis were identified. The proportion of treatment success was 100% (95% CI 54.1-100) in CNS, 91.7% (95% CI 61.5-99.8) in cutaneous, 78.6% (95% CI 49.2-95.3) in pulmonary and 71.5% (95% CI 29.0-96.3) in upper airway disease. The use of infliximab was associated with a reduction prednisone dose by 50%. CONCLUSION: Infliximab is possibly an effective therapy for refractory sarcoidosis, with the greatest value in neurologic and cutaneous manifestations. Across all disease presentations, infliximab facilitated a clinically relevant reduction in corticosteroid dose. Relapse is common after discontinuation of infliximab.

Impact of the COVID-19 pandemic on juvenile idiopathic arthritis presentation and research recruitment: results from the CAPRI registry.

OBJECTIVE: The COVID-19 pandemic has disrupted healthcare delivery and clinical research worldwide, with data from areas most affected demonstrating an impact on rheumatology care. This study aimed to characterize the impact of the pandemic on the initial presentation of JIA and JIA-related research in Canada. METHODS: Data collected from the Canadian Alliance of Pediatric Rheumatology Investigators JIA Registry from the year pre-pandemic (11 March 2019 to 10 March 2020) was compared with data collected during the first year of the pandemic (11 March 2020 to 10 March 2021). Outcomes included time from symptom onset to first assessment, disease severity at presentation and registry recruitment. Proportions and medians were used to describe categorical and continuous variables, respectively. RESULTS: The median time from symptom onset to first assessment was 138 (IQR 64-365) days pre-pandemic vs 146 (IQR 83-359) days during the pandemic. The JIA category frequencies remained overall stable (44% oligoarticular JIA pre-pandemic, 46.8% pandemic), except for systemic JIA (12 cases pre-pandemic, 1 pandemic). Clinical features, disease activity (cJADAS10), disability (CHAQ) and quality of life (JAQQ) scores were similar between the two cohorts. Pre-pandemic, 225 patients were enrolled, compared with 111 in the pandemic year, with the greatest decrease from March to June 2020. CONCLUSIONS: We did not observe the anticipated delay in time to presentation or increased severity at presentation, suggesting that, within Canada, care adapted well to provide support to new patient consults without negative impacts. The COVID-19 pandemic was associated with an initial 50% decrease in registry enrolment but has since improved.

Pediatric Patients with a Dual Diagnosis of Inflammatory Bowel Disease and Chronic Recurrent Multifocal Osteomyelitis.

ABSTRACT: There is a paucity of information about the epidemiology, pathophysiology, and treatment of patients with a dual diagnosis of inflammatory bowel disease (IBD) and chronic recurrent multifocal osteomyelitis (CRMO). A retrospective chart review was performed of patients at McMaster Children's Hospital with a diagnosis of either IBD or CRMO, to identify those with the dual diagnosis over a 10-year period. A dual diagnosis was identified in seven patients. Most patients (6/7) had a diagnosis of IBD first and were subsequently diagnosed with CRMO. At the time of CRMO diagnosis, IBD treatment regimens included one or more of, sulfasalazine (1/6), infliximab (3/6), adalimumab (1/6), or no treatment (1/6). Although the etiology of the link remains unknown, there does not seem to be an association to a specific IBD subtype, age, or treatment. Our patient population demonstrated a response to biologic agents, specifically tumor necrosis factor-α inhibitors, as treatment for both conditions.

Interprofessional education in the rural environment to enhance multidisciplinary care in future practice: Breaking down silos in tertiary health education.

OBJECTIVE: Western Sydney University has implemented a rural interprofessional learning programme to promote collaborative care approaches to enhance cross-discipline communications, improve knowledge and clarity of roles and improve patient care and outcomes. DESIGN: Rural interprofessinal learning is an interprofessional educational approach, consisting of simulations of complex health events. Simulation methodology frames the study with a focus on human interaction. A mixed-methods evaluation has been conducted, incorporating pre- and post- event participant surveys along with semi-structured focus groups. SETTING: Simulations are conducted in the rural setting, including community settings, working farms and rural hospitals. MAIN OUTCOME MEASURES: Reflexive thematic analysis was used to identify themes measuring students' perceptions of interdisciplinary care, knowlede of other health discipline roles and skills and how they believe the exercise will influence their future practice. Facilitator feedback regarding the efficacy of the simulations was also recorded and analysed using reflexive thematic analysis. PARTICIPANTS: Care of simulated patient(s)/bystander(s) is primarily provided by paramedicine, nursing and medical students; however, increasing interest has expanded the programme to include students from a range of allied health professions. Simulations are facilitated by a multidisciplinary team of experienced practitioners and specialists. INTERVENTION: Four rural interprofessional learning events have been held. RESULTS: 120 students have participated in the evaluation. Findings include increased understanding of the contributions of other disciplines in enhancing patient care, team approaches, cross-discipline communication and a need to engage in collaborative care in future practice. CONCLUSION: Creating a collaborative learning environment creates a culture of multidisciplinary care, enhancing patient care and improving outcomes. The rural interprofessional learning model is an effective interprofessional educational approach, which can be repeated, refined and improved for continual professional development.

Transition Readiness in Adolescents With Juvenile Idiopathic Arthritis and Childhood-Onset Systemic Lupus Erythematosus.

OBJECTIVE: The transition from pediatric to adult rheumatology care represents a particularly vulnerable time for patients with juvenile idiopathic arthritis (JIA) and childhood-onset systemic lupus erythematosus (cSLE). Improving self-management skills is important in optimizing health care transition. The study's objectives were to 1) examine variability in transition readiness of adolescents and young adults within and between different ages, sexes, and disease types; 2) determine the association between age and transition readiness; and 3) identify specific challenges to transition readiness for adolescents. METHODS: Over 1 year, patients 14 to 20 years of age with JIA or cSLE were recruited from pediatric transition and young adult clinics at a single academic institution. Participants completed the 14-item Transition-Q at a single time point. Total scores range from 0 to 100; higher scores indicate greater health care self-management skills as a proxy for transition readiness. Descriptive statistics summarized patient characteristics and Transition-Q scores for the population. Regression analyses determined the association between age, sex, and disease type and Transition-Q score. RESULTS: Among 70 participants, 61 had JIA and 9 cSLE (mean disease duration 4.6 years). The mean (SD) total Transition-Q score was 59.8 (14.9). Age was significantly associated with Transition-Q score (standardized ß = 0.372l P = 0.002). The most commonly reported challenges were seeing the physician alone (without parents), making one's own appointments, picking up prescriptions, and independent transportation for appointments. CONCLUSION: Transition readiness appears to increase with patient age. There is significant variability in Transition-Q scores between patients of the same age, suggesting that an individualized approach to improving self-management skills is necessary.

Prevalence and trajectory of erosions, synovitis, and bone marrow edema in feet of patients with early rheumatoid arthritis.

Despite erosions being as prevalent in feet as in hands in patients with rheumatoid arthritis (RA), their development in relation to synovitis and bone marrow edema (BME) have mainly been studied in hands. This study examines the prevalence and longitudinal trajectory of erosions, BME, and synovitis in metatarsophalangeal joints (MTPJs) in patients with early RA over 2 years of treatment. We also describe correlations between erosions, synovitis, and BME at the joint level. Magnetic resonance imaging (MRI) of the most symptomatic forefoot was acquired at baseline, year 1, and ≥ 2 years. Metatarsophalangeal joints 2-5 were scored by a radiologist for erosions, synovitis, and BME according to OMERACT guidelines. Patients were treated per standard of care. Thirty-two patients with early RA were included. Significant reductions in overall synovitis scores, MTPJ2, and MTPJ3 synovitis scores were seen between year 1 and ≥ 2 years. Overall BME scores improved in year 1 and were sustained at ≥ 2 years. BME improved in MTPJ2, MTPJ3, and MTPJ4. Overall erosions did not significantly change. Positive correlations were seen between changes in synovitis and BME in MTPJ2 and MTPJ5. In patients with early RA, standard of care was associated with overall reductions in synovitis by year 2, BME by year 1, and no progression in overall erosion scores on MRI. MTPJ2 and MTPJ3 appeared to be the most active joints. Improvements in synovitis were noted in MTPJ2 and MTPJ3 and reductions in BME in MTPJ2, MTPJ3, and MTPJ4, while other MTPJs did not progress. Key Points • This is one of the few MRI studies that examined longitudinal changes in imaging outcomes in early RA at the joint level in feet. • Erosions, synovitis, and bone marrow edema (BME) visualized on magnetic resonance imaging were most prevalent in metatarsophalangeal joints (MTPJ) 2 and 3 in patients with early rheumatoid arthritis (RA). • Standard of care was associated with improvements in synovitis in MTPJ2 and MTPJ3 and improvements in BME in MTPJ2, MTPJ3, and MTPJ4 over 2 years of treatment.

Contextualizing temporal arterial magnetic resonance angiography in the diagnosis of giant cell arteritis: a retrospective cohort study.

OBJECTIVES: Imaging modalities have become common in evaluating patients for a possible diagnosis of GCA. This study seeks to contextualize how temporal arterial magnetic resonance angiography (TA-MRA) can be used in facilitating the diagnosis of GCA. METHODS: A retrospective cohort study was performed on patients who had been previously referred to a rheumatologist for evaluation of possible GCA in Hamilton, Ontario, Canada. Data including clinical features, inflammatory markers, imaging, and biopsy results were extracted. Multivariable logistic regression model to predict the diagnosis of GCA. Using these models, the utility of TA-MRA in series with or in parallel to clinical evaluation was demonstrated across the cohort as well as in subgroups defined by biopsy and imaging status. RESULTS: In total 268 patients had complete data. Those diagnosed with biopsy- and/or imaging-positive GCA were more likely to demonstrate classic features including jaw claudication and vision loss. Clinical multivariable modelling allowed for fair discriminability [receiver operating characteristic (ROC) 0.759, 95% CI: 0.703, 0.815] for diagnosing GCA; there was excellent discriminability in facilitating the diagnosis of biopsy-positive GCA (ROC 0.949, 0.898-1.000). When used in those with a pre-test probability of 50% or higher, TA-MRA had a positive predictive value of 93.0%; in those with a pre-test probability of 25% or less TA-MRA had a negative predictive value of 89.5%. CONCLUSION: In those with high disease probability, TA-MRA can effectively rule in disease (and replace temporal artery biopsy). In those with low to medium probability, TA-MRA can help rule out the disease, but this continues to be a challenging diagnostic population.

Fecal microbiome differs between patients with systemic sclerosis with and without small intestinal bacterial overgrowth.

Introduction: Gastrointestinal manifestations of systemic sclerosis affect up to 90% of patients, with symptoms including diarrhea and constipation. Small intestinal bacterial overgrowth is a condition associated with increased numbers of pathogenic bacteria in the small bowel. While currently unknown, it has been suggested that dysregulation of the fecal microbiota may play a role in the development of systemic sclerosis and small intestinal bacterial overgrowth. Objectives: Our study aimed to describe the fecal microbiota of patients with systemic sclerosis and compare it between those with and without a diagnosis of small intestinal bacterial overgrowth. We also compared the fecal microbiota of systemic sclerosis patients with that of healthy controls to understand the association between particular bacterial taxa and clinical gastrointestinal manifestations of systemic sclerosis. Methods: A total of 29 patients with systemic sclerosis underwent breath testing to assess for small intestinal bacterial overgrowth, provided stool samples to determine taxonomic assignments, and completed the University of California Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract 2.0, which details symptoms and quality-of-life factors. Stool samples were compared between systemic sclerosis patients with and without small intestinal bacterial overgrowth, and between patients with systemic sclerosis and a healthy control cohort (n = 20), aged 18-80 years. Results: Fecal microbiome analyses demonstrated differences between systemic sclerosis patients with and without small intestinal bacterial overgrowth and differences in the diversity of species between healthy controls and patients with systemic sclerosis. Trends were also observed in anticentromere antibody systemic sclerosis patients, including higher Alistipies indistincus spp. levels associated with increased methane levels of breath gas testing and higher Slakia spp. levels associated with increased rates of fecal soiling. Conclusions: Our results suggest that changes to the fecal microbiome occur in patients with small intestinal bacterial overgrowth and systemic sclerosis when compared to healthy controls. As a cross-sectional study, the potential pathophysiologic role of an altered microbiome in the development of systemic sclerosis was not considered and hence needs to be further investigated.

Childhood and adolescent mental health of NICU graduates: an observational study.

OBJECTIVE: To investigate the mental health of children and adolescents admitted to neonatal intensive/special care units (NICUs) in infancy. METHODS: This cross-sectional study used a provincially representative cohort from the 2014 Ontario Child Health Study. Parents provided data on psychiatric disorders using the MINI International Neuropsychiatric Interview for Children and Adolescents in 3141 children aged 4-11 years (NICU n=389; control n=2752) and in 2379 children aged 12-17 years (NICU n=298; control n=2081). Additionally, 2235 adolescents aged 12-17 years completed the interview themselves (NICU n=285; control n=1950). Odds of psychiatric disorder were compared in those admitted and controls. RESULTS: Based on parent reports, NICU graduates aged 4-11 years had increased adjusted ORs (95% CI) of 1.78 (1.39 to 2.28) for any psychiatric disorder, with a marginal prevalence of 32.4% in NICU participants and 27.6% in controls. At this age, NICU graduates also had increased ORs of 1.74 (1.25 to 2.40) for psychiatric comorbidity, 1.48 (1.04 to 2.11) for oppositional defiant disorder, 1.61 (1.19 to 2.19) for attention-deficit hyperactivity disorder, 4.11 (2.33 to 7.25) for separation anxiety disorder and 2.13 (1.37 to 3.31) for specific phobia. At 12-17 years, 40.5% and 30.5% of NICU graduates and 30.6% and 17.9% of controls had any psychiatric disorder as reported by parents and self-report, respectively. Parents and adolescents, respectively, reported increased adjusted ORs (95% CI) of 1.63 (1.18 to 2.26) and 1.55 (1.13 to 2.11) for any disorder, 1.64 (1.06 to 2.54) and 1.74 (1.11 to 2.73) for psychiatric comorbidity, and 1.89 (1.22 to 2.93) and 3.17 (2.03 to 4.95) for oppositional defiant disorder. CONCLUSIONS: NICU graduates are at increased risk for psychiatric disorders during childhood and adolescence.

Ultrasonography supplements clinical exam to improve early rheumatoid arthritis disease activity monitoring in metatarsophalangeal joints.

INTRODUCTION: Compared with clinical examination (CE), ultrasonography (US) provides additional and more accurate assessment of inflammation and visualization of structural damage. To better understand the effectiveness of US in metatarsophalangeal joints (MTPJs), we compared disease activity in MTPJs 2-5 assessed by CE and US, with magnetic resonance imaging (MRI) as reference standard. METHOD: Treatment-naïve adult patients with early RA (ACR criteria, disease duration < 2 years) were consecutively recruited. MTPJs 2-5 were assessed for swelling and tenderness, and imaged by US (Esaote MyLab70). The most symptomatic foot was imaged by peripheral MRI (1.0 Tesla). US was semiquantitatively graded for synovial thickening (ST) and power Doppler (PD) (0-3), and erosions (yes/no). MRI was semiquantitatively graded for bone marrow edema (BME), synovitis, and erosions (OMERACT). Kappa agreement, sensitivity, specificity, and predictive values were analyzed using cut-offs at ST ≥ 2, PD ≥ 1, and MRI synovitis and BME at both ≥ 1 and ≥ 2. RESULTS: This study included 39 patients (85% female, mean (SD) age = 51.6 (10.3)). Using MRI synovitis and BME grade ≥ 2 as the reference, PD had superior sensitivity (82%) and kappa agreement (k = 0.43) than swollen joint count (55%, k = 0.20), but similar high specificity (88%, 83%). ST and PD were often observed in clinically asymptomatic MTPJs. US detected very few MRI erosions, but several observed erosions corresponded to grade ≥ 2 MRI erosions. CONCLUSION: Clinical swelling and PD are highly specific for active inflammation in the MTPJs. US supplemented CE by allowing observation of subclinical inflammation and structural damage. Key Points • Ultrasonography detected many subclinical synovial inflammations in metatarsophalangeal joints (MTPJs), many confirmed by MRI • Ultrasonography may best be used clinically to supplement clinical examination by assessing non-swollen joints • Ultrasonography provided quick method of visualizing bone erosions that were grade ≥ 2 on MRI.

Pulmonary arterial hypertension screening practices in scleroderma patients among Canadian rheumatologists.

Background: Current international guidelines recommend annual screening for pulmonary arterial hypertension with transthoracic echocardiogram and pulmonary function testing in all patients with scleroderma (systemic sclerosis). Our objectives were to determine Canadian rheumatologists' screening practices for pulmonary arterial hypertension in patients with systemic sclerosis and identify reasons why current guideline recommendations may not be followed. Methods: A survey was emailed to all Canadian Rheumatology Association members. They self-identified as systemic sclerosis experts or non-experts and provided basic demographic data. Participants were asked how frequently they screened with transthoracic echocardiogram and pulmonary function testing and, if applicable, why they did not adhere to recommendations. Results: A total of 71 rheumatologists participated, of whom 43 identified as non-experts. Overall, 81.4% ordered annual transthoracic echocardiogram and 77.6% annual pulmonary function testing. Rates of annual transthoracic echocardiogram testing were similar between experts and non-experts, whereas experts ordered annual pulmonary function testing more often. Clinicians with a higher proportion of systemic sclerosis patients in their practice were more likely to follow guidelines. There was an inverse relationship between years in practice and adherence to screening guidelines. The most common reason for not following screening guidelines was disagreement with recommendations, followed by unfamiliarity with guidelines. Conclusions: Pulmonary arterial hypertension screening rates remain sub-optimal in Canada but have improved since 2012. Failure to adopt guidelines is due to rheumatologists disagreeing with or not knowing current recommendations. Future studies should examine why rheumatologists disagree with guidelines and how to improve awareness.

Effects of Mowing and Prescribed Fire on Plant Community Structure and Function in Rare Coastal Sandplains, Nantucket Island, MA, USA.

Coastal sandplains provide habitat for a suite of rare and endangered plant and wildlife species in the northeastern United States. These early successional plant communities were maintained by natural and anthropogenic disturbances including salt spray, fire, and livestock grazing, but over the last 150 years, a decrease in anthropogenic disturbance frequency and intensity has resulted in a shift towards woody shrub dominance at the expense of herbaceous taxa. This study quantified the effects of more than a decade of dormant season disturbance-based vegetation management (mowing and prescribed fire) on coastal sandplain plant community composition on Nantucket Island, Massachusetts, USA. We used time-series plant cover data from two similar sites to evaluate the effectiveness of disturbance management for restoring herbaceous species cover and reducing woody shrub dominance. Our results indicate that applying management outside of the peak of the growing season has not been effective in maintaining or increasing the cover of herbaceous species. While management activities resulted in significant (P < 0.01) increases in herbaceous species immediately after treatment, woody species recolonized and dominated treated sites within 3-years post treatment at the expense of graminoids and forbs. These results highlight the difficulties associated with directing ecological succession using disturbance-based management to maintain rare, herbaceous species in coastal sandplain systems that were once a prevalent landscape component under historically chronic anthropogenic disturbance. Further experimentation with growing season disturbance-based management and different combinations of management techniques could provide insights into management alternatives for maintaining herbaceous conservation targets in coastal sandplains.
