- Abstract
Introduction:The increased relative risk of heart failure (HF) due to systemic lupus erythematosus (SLE) is greatest among youth and young adults, but the etiology is unclear. We identified risk factors for HF in youth and young adults with SLE and evaluated associations between cardiac manifestations of SLE and HF.Methods:Incident SLE cases without antecedent HF were identified using Clinformatics? (OptumInsight, MN) US claims data (2000-2016), and categorized by age of SLE onset (youth 5-25, young adult 25-44). The primary outcome was the first HF diagnosis (ICD9-CM 428.x), with acute-onset (< 6 months after SLE) or delayed-onset presentation. We ran separate multivariable logistic regressions to identify baseline factors associated with acute-onset HF or predictive of delayed-onset HF. Pre-specified interactions by age of SLE onset were assessed using likelihood ratio tests.Results:There were 526 (2%) HF cases among 4112 youth and 21904 young adults with SLE during a median follow-up of 2.5 yrs after SLE diagnosis [IQR 1.4 - 4.5]. 37 (60%) HF diagnoses in youth were acute-onset compared to 35% of adults, and co-occurred with myopericarditis, endocarditis, or valvular insufficiency in 35%, 14%, and 24% of cases, respectively. Nephritis, antiphospholipid antibody syndrome, myopericarditis and valvular disease at SLE presentation were independently associated with delayed-onset HF (Table). The traditional cardiovascular risk factor most strongly associated with delayed-onset HF was hypertension. There were no significant interactions between major SLE manifestations or cardiovascular risk factors and age of SLE onset.Conclusion:In addition to renal disease and hypertension, cardiac manifestations at initial SLE presentation may be a risk factor for heart failure among youth and young adults, and therefore may warrant routine cardiology follow-up. Hypertension remains an important risk factor across all ages and should be managed aggressively.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that is increasingly affecting pediatric and adult populations. Neuropsychiatric manifestations (ie, cognitive dysfunction and mood disorders) appear to occur with greater severity and poorer prognosis in childhood‐onset SLE (cSLE) versus adult‐onset SLE, negatively impacting school function, self‐management, and psychosocial health, as well as lifelong health‐related quality of life. In this review, we describe pathogenic mechanisms active in cSLE, such as maladaptive inflammatory processes and ischemia, which are hypothesized to underpin central phenotypes in patients with cSLE, and the role of alterations in protective central nervous system (CNS) barriers (ie, the blood–brain barrier) are also discussed. Recent findings derived from novel neuroimaging approaches are highlighted because the methods employed in these studies hold potential for identifying CNS abnormalities that would otherwise remain undetected with conventional multiple resonance imaging studies (eg, T2‐weighted or fluid‐attenuated inversion recovery sequences). Furthermore, we propose that a more robust presentation of neuropsychiatric symptoms in cSLE is in part due to the harmful impact of a chronic inflammatory insult on a developing CNS. Although the immature status of the CNS may leave patients with cSLE more vulnerable to harboring neuropsychiatric manifestations, the same property may represent a greater urgency to reverse the maladaptive effects associated with a proneuroinflammatory state, provided that effective diagnostic tools and treatment strategies are available. Finally, considering the crosstalk among the CNS and other organ systems affected in cSLE, we postulate that a finer understanding of this interconnectivity and its role in the clinical presentation in cSLE is warranted.

- Abstract
Objective: Childhood-onset systemic lupus erythematosus (SLE) is associated with high risk for organ damage, which may be mitigated by early diagnosis and treatment. We characterized health care utilization for youth in the year preceding SLE diagnosis compared to controls.Methods: Using Clinformatics DataMart (OptumInsight) de-identified administrative data from 2000 to 2013, we identified 682 youth ages 10-24 years with new-onset SLE (≥3 International Classification of Diseases, Ninth Revision codes for SLE 710.0, each >30 days apart), and 1,364 age- and sex-matched healthy controls. We compared the incidence of ambulatory, emergency, and inpatient visits 12 months before SLE diagnosis and frequency of primary diagnoses. We examined subject characteristics associated with utilization preceding SLE diagnosis.Results: Youth with SLE had significantly more visits in the year preceding diagnosis than controls across ambulatory (incidence rate ratio [IRR] 2.48, P < 0.001), emergency (IRR 3.42, P < 0.001), and inpatient settings (IRR 3.02, P < 0.001). The most frequent acute-care diagnoses and median days to SLE diagnosis were: venous thromboembolism (313, interquartile range [IQR] 18-356), thrombocytopenia (278, IQR 39-354), chest pain (73, IQR 29.5-168), fever (52, IQR 17-166), and acute kidney failure (14, IQR 5-168). Having a psychiatric diagnosis prior to SLE diagnosis was strongly associated with increased utilization across all settings.Conclusion: Youth with SLE have high health care utilization throughout the year preceding SLE diagnosis. Examining variable diagnostic trajectories of youth requiring acute care preceding SLE diagnosis, and increased attention to psychiatric morbidity, may help improve care for youth with new-onset SLE.

- Abstract
Objective: To identify factors contributing to cognitive impairment in children with lupus nephritis.Study Design: A cross-sectional analysis of a large multicenter national cohort of children with chronic kidney disease (CKD) using standardized measures to determine baseline neuropsychiatric function and health-related quality of life (HRQoL) in children with lupus nephritis (n = 34), and to compare baseline function with that in children with other forms of glomerular CKD (gCKD; n = 171). We used inverse probability weighting via a logistic model for propensity score analysis to achieve balance between children with lupus nephritis and those with other glomerular causes of CKD, adjusting for known confounders. We used linear regression models to compare neurocognitive outcomes between exposure groups, adjusting for current prednisone use and testing for an interaction between current prednisone use and lupus nephritis, and to test for an association between cognitive function and HRQoL.Results: Current prednisone use was independently associated with worse attention (P < .01) and better adaptive skills (P = .04), and there was a significant interaction between current prednisone use and lupus nephritis for internalizing problems, with worse parent-reported internalizing problems in children with lupus nephritis on prednisone (P = .047). Better parent-reported HRQoL was associated with better visual memory (P = .01), and better child-reported HRQoL was associated with better attention (P < .01) and inhibitory control (P < .01). Both parent and child HRQoL were associated with better measures of executive function (P = .02 and < .001, respectively).Conclusion: Children with lupus nephritis have comparable or better cognitive function than their peers with other gCKDs, which is reassuring given the multiorgan and lifelong complications associated with lupus.

Objectives Genome-wide association studies (GWAS) have identified loci associated with estimated glomerular filtration rate (eGFR). Few LN risk loci have been identified to date. We tested the association of SLE and eGFR polygenic risk scores (PRS) with repeated eGFR measures from children and adults with SLE. Methods Patients from two tertiary care lupus clinics that met ≥4 ACR and/or SLICC criteria for SLE were genotyped on the Illumina MEGA or Omni1-Quad arrays. PRSs were calculated for SLE and eGFR, using published weighted GWA-significant alleles. eGFR was calculated using the CKD-EPI and Schwartz equations. We tested the effect of eGFR- and SLE-PRSs on eGFR mean and variance, adjusting for age at diagnosis, sex, ancestry, follow-up time, and clinical event flags. Results We included 1158 SLE patients (37% biopsy-confirmed LN) with 36 733 eGFR measures over a median of 7.6 years (IQR: 3.9–15.3). LN was associated with lower within-person mean eGFR [LN: 93.8 (s. d. 26.4) vs non-LN: 101.6 (s. d. 17.7) mL/min per 1.73 m2 ; P < 0.0001] and higher variance [LN median: 157.0 (IQR: 89.5, 268.9) vs non-LN median: 84.9 (IQR: 46.9, 138.2) (mL/min per 1.73 m2)2; P < 0.0001]. Increasing SLE-PRSs were associated with lower mean eGFR and greater variance, while increasing eGFR-PRS was associated with increased eGFR mean and variance. Conclusion We observed significant associations between SLE and eGFR PRSs and repeated eGFR measurements, in a large cohort of children and adults with SLE. Longitudinal eGFR may serve as a powerful alternative outcome to LN categories for discovery of LN risk loci. [ABSTRACT FROM AUTHOR]

Objective To phenotype SLE based on symptom burden (disease damage, system involvement and patient reported outcomes), with a specific focus on objective and subjective cognitive function. Methods SLE patients ages 18–65 years underwent objective cognitive assessment using the ACR Neuropsychological Battery (ACR-NB) and data were collected on demographic and clinical variables, disease burden/activity, health-related quality of life (HRQoL), depression, anxiety, fatigue and perceived cognitive deficits. Similarity network fusion (SNF) was used to identify patient subtypes. Differences between the subtypes were evaluated using Kruskal–Wallis and χ2 tests. Results Of the 238 patients, 90% were female, with a mean age of 41 years (s. d. 12) and a disease duration of 14 years (s. d. 10) at the study visit. The SNF analysis defined two subtypes (A and B) with distinct patterns in objective and subjective cognitive function, disease burden/damage, HRQoL, anxiety and depression. Subtype A performed worst on all significantly different tests of objective cognitive function (P < 0.03) compared with subtype B. Subtype A also had greater levels of subjective cognitive function (P < 0.001), disease burden/damage (P < 0.04), HRQoL (P < 0.001) and psychiatric measures (P < 0.001) compared with subtype B. Conclusion This study demonstrates the complexity of cognitive impairment (CI) in SLE and that individual, multifactorial phenotypes exist. Those with greater disease burden, from SLE-specific factors or other factors associated with chronic conditions, report poorer cognitive functioning and perform worse on objective cognitive measures. By exploring different ways of phenotyping SLE we may better define CI in SLE. Ultimately this will aid our understanding of personalized CI trajectories and identification of appropriate treatments.

- Abstract
Objective: To investigate differences in risk factors for depression and anxiety, such as central nervous system involvement in systemic lupus erythematosus (SLE)/mixed connective tissue disease (MCTD), by comparing youth with SLE/MCTD to peers with type 1 diabetes mellitus (T1D).Study Design: We conducted a cross-sectional study of 50 outpatient pairs, ages 8 years and above, matching subjects with SLE/MCTD and T1D by sex and age group. We screened for depression, suicidal ideation, and anxiety using the Patient Health Questionnaire-9 and the Screen for Childhood Anxiety Related Emotional Disorders, respectively. We collected parent-reported mental health treatment data. We compared prevalence and treatment rates between subjects with SLE/MCTD and T1D, and identified disease-specific risk factors using logistic regression.Results: Depression symptoms were present in 23%, suicidal ideation in 15%, and anxiety in 27% of participants. Compared with subjects with T1D, subjects with SLE/MCTD had lower adjusted rates of depression and suicidal ideation, yet poorer rates of mental health treatment (24% vs 53%). Non-White race/ethnicity and longer disease duration were independent risk factors for depression and suicidal ideation. Depression was associated with poor disease control in both groups, and anxiety with insulin pump use in subjects with T1D.Conclusion: Depression and anxiety are high and undertreated in youth with SLE/MCTD and T1D. Focusing on risk factors such as race/ethnicity and disease duration may improve their mental health care. Further study of central nervous system and other disease-related factors may identify targets for intervention. [ABSTRACT FROM AUTHOR]- Published

Objectives Genetics plays an important role in SLE risk, as well as osteonecrosis (ON), a significant and often debilitating complication of SLE. We aimed to identify genetic risk loci for ON in people with childhood-onset (cSLE) and adult-onset (aSLE) SLE. Methods We enrolled participants from two tertiary care centres who met classification criteria for SLE. Participants had prospectively collected clinical data and were genotyped on a multiethnic array. Un-genotyped single nucleotide polymorphisms (SNPs) were imputed, and ancestry was inferred using principal components (PCs). Our outcome was symptomatic ON confirmed by imaging. We completed time-to-ON and logistic regression of ON genome-wide association studies (GWASs) with covariates for sex, age of SLE diagnosis, five PCs for ancestry, corticosteroid use and selected SLE manifestations. We conducted separate analyses for cSLE and aSLE and meta-analysed results using inverse-variance weighting. Genome-wide significance was P < 5 × 10−8. Results The study included 940 participants with SLE, 87% female and 56% with cSLE. ON was present in 7.6% (n = 71). Median age of SLE diagnosis was 16.9 years (interquartile range [IQR]: 13.5, 29.3), with median follow-up of 8.0 years (IQR: 4.2, 15.7). Meta-GWAS of cSLE and aSLE time-to-ON of 4 431 911 SNPs identified a significant Chr.2 SNP, rs34118383 (minor allele frequency = 0.18), intronic to WIPF1 (hazard ratio = 3.2 [95% CI: 2.2, 4.8]; P = 1.0 × 10−8). Conclusion We identified an intronic WIPF1 variant associated with a 3.2 times increased hazard for ON (95% CI: 2.2, 4.8; P = 1.0 × 10−8) during SLE follow-up, independent of corticosteroid exposure. The effect of the SNP on time-to-ON was similar in cSLE and aSLE. This novel discovery represents a potential ON risk locus. Our results warrant replication. [ABSTRACT FROM AUTHOR]

Background: Childhood-onset Systemic Lupus Erythematosus (cSLE) is an autoimmune disease associated with fatigue, mood symptoms, and pain. Fortunately, these symptoms are potentially modifiable with psychological intervention such as cognitive-behavioral therapy (CBT). The Treatment and Education Approach for Childhood-onset Lupus (TEACH) program is a CBT intervention developed to target these symptoms for adolescents and young adults with cSLE. This pilot randomized controlled trial (RCT) aims to determine the feasibility and effect of TEACH for youth with cSLE. Adjustments to the study protocol following the COVID-19 pandemic are also described. Methods: This two-arm multisite RCT will explore the feasibility (primary outcome) and effect (secondary outcome) of a remotely delivered TEACH protocol. Participants will be randomized to a six-week remotely delivered TEACH program plus medical treatment as usual (TAU) or TAU alone. We will include patients ages 12–22 years presenting to rheumatology clinics from six sites. Validated measures of fatigue, depressive symptoms, and pain will be obtained at baseline and approximately eight and 20 weeks later. Protocol adjustments were also made due to the COVID-19 pandemic, in collaboration with the investigative team, which included patients and caregivers. Conclusions: Findings from this multi-site RCT aim to document the feasibility of TEACH and provide an estimate of effect of a remotely delivered TEACH protocol on fatigue, depression, and pain symptoms in youth with cSLE as compared to standard medical treatment alone. This findings may positively impact clinical care for patients with cSLE. Clinical trials.gov registration: NCT04335643. [ABSTRACT FROM AUTHOR]

SYSTEMIC lupus erythematosus , *HEALTH equity , *HISPANIC American women , *INCOME inequality , *ALASKA Natives - Abstract
Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune disease disproportionally afflicting women and, in particular, American Indian/Alaska Native, Black, and Hispanic women. These groups of women have significantly worse SLE-related health outcomes which are partially attributable to their exposure to marginalizing and interconnecting social issues like racism, sexism, economic inequality, and more. Although these groups of women have higher rates of SLE and though it is well known that they are at risk of exposure to marginalizing social phenomena, relatively little SLE literature explicitly links and addresses the relationship between marginalizing social issues and poor SLE-health outcomes among these women. Therefore, we developed a community-engaged partnership with two childhood-SLE diagnosed women of color to identify their perspectives on which systemic issues impacted on their SLE health-related outcomes. Afterward, we used Cochrane guidelines to conduct a rapid review associated with these identified issues and original SLE research. Then, we adapted an ecological model to illustrate the connection between systems issues and SLE health outcomes. Finally, we provided recommendations for ways to research and clinically mitigate SLE health inequities. [ABSTRACT FROM AUTHOR]

Digital technologies have enabled new temporalities of media consumption in the home. Through a field study of home television viewing practices, we investigated temporal orderings of television watching. In contrast to traditional pictures of television use, our evidence suggests that rhythms across households play an important role in shaping television watching. Further, we found a flexibility and openness within the patterns of television viewing that we refer to as 'plasticity.' Our data suggest that plasticity and rhythms co-exist and together compose the qualitative experience of domestic television time; an understanding of both aspects of temporality suggests an approach for the design of future television technologies.

The translation of research findings into clinical practice is challenging, especially fields like in pediatric rheumatology, where the evidence base is limited, there are few clinical trials, and the conditions are rare and heterogeneous. Implementation science methodologies have been shown to reduce the research- to- practice gap in other clinical settings may have similar utility in pediatric rheumatology. This paper describes the key discussion points from the inaugural Childhood Arthritis and Rheumatology Research Alliance Implementation Science retreat held in February 2020. The aim of this report is to synthesize those findings into an Implementation Science Roadmap for pediatric rheumatology research. This roadmap is based on three foundational principles: fostering curiosity and ensuring discovery, integration of research and quality improvement, and patient-centeredness. We include six key steps anchored in the principles of implementation science. Applying this roadmap will enable researchers to evaluate the full range of research activities, from the initial clinical design and evidence acquisition to the application of those findings in pediatric rheumatology clinics and direct patient care.

The universal nine-amino-acid transactivation domains (9aaTADs) have been identified in numerous transcription activators. Here, we identified the conserved 9aaTAD motif in all nine members of the specificity protein (SP) family. Previously, the Sp1 transcription factor has been defined as a glutamine-rich activator. We showed by amino acid substitutions that the glutamine residues are completely dispensable for 9aaTAD function and are not conserved in the SP family. We described the origin and evolutionary history of 9aaTADs. The 9aaTADs of the ancestral Sp2 gene became inactivated in early chordates. We next discovered that an accumulation of valines in 9aaTADs inactivated their transactivation function and enabled their strict conservation during evolution. Subsequently, in chordates, Sp2 has duplicated and created new paralogs, Sp1, Sp3, and Sp4 (the SP1–4 clade). During chordate evolution, the dormancy of the Sp2 activation domain lasted over 100 million years. The dormant but still intact ancestral Sp2 activation domains allowed diversification of the SP1–4 clade into activators and repressors. By valine substitution in the 9aaTADs, Sp1 and Sp3 regained their original activator function found in ancestral lower metazoan sea sponges. Therefore, the vertebrate SP1–4 clade could include both repressors and activators. Furthermore, we identified secondary 9aaTADs in Sp2 introns present from fish to primates, including humans. In the gibbon genome, introns containing 9aaTADs were used as exons, which turned the Sp2 gene into an activator. Similarly, we identified introns containing 9aaTADs used conditionally as exons in the (SP family-unrelated) transcription factor SREBP1, suggesting that the intron-9aaTAD reservoir is a general phenomenon.

To examine if parent illness uncertainty is indirectly associated with child depression, anxiety, and HRQOL in the CKD/SLE population. Parent–child dyads (N = 31) from outpatient rheumatology and nephrology clinics included children (ages 9–18) diagnosed with CKD (Stage 1, 2, or nephrotic syndrome) or SLE. Parents completed demographic and uncertainty measures and children completed uncertainty, depression, anxiety, and HRQOL measures. This cross-sectional study examined mediational models using the percentile bootstrapping method. Parent uncertainty had an indirect effect on child depression, anxiety, and HRQOL through the mediator, child uncertainty. In other words, parents' illness uncertainty regarding their child's condition correlates to the child's illness uncertainty, which then is associated with the child's mental health and wellbeing. Reverse mediations illustrated that parent uncertainty did not mediate child uncertainty and outcome variables. Results extend previous research by examining parent and child illness uncertainty in understudied conditions (CKD/SLE) and the relationship to outcome variables commonly related to depression (e.g., anxiety and HRQOL). Findings allow health psychologists and medical personnel to understand the impact of uncertainty on the child's wellbeing and HRQOL. Clinical implications, including using specialized interventions to address illness uncertainty, are discussed. [ABSTRACT FROM AUTHOR]

The timing and etiology of diastolic impairment in pediatric-onset systemic lupus erythematosus (SLE) are poorly understood. We compared echocardiographic metrics of left ventricular diastolic function in children at SLE diagnosis to controls and identified factors associated with diastolic indices. Echocardiograms of children aged 5–18 years within 1 year of SLE diagnosis and age-/sex-matched controls were retrospectively read by blinded cardiologists. Clinical characteristics were abstracted separately. Z-scores for diastolic indices (E/A, e′, E/e′, and isovolumetric relaxation time (IVRT)) were calculated using published normative data and study controls, and compared using linear mixed-effects models adjusted for blood pressure. Pericardial effusions and valvular disease were also evaluated. Linear regression was used to identify factors associated with diastolic measures. 85 children with incident SLE had echocardiograms performed a median of 6 days after diagnosis (interquartile range (IQR) 1–70). Prior cumulative prednisone exposure was minimal (median 60 mg, IQR 0–1652). SLE cases had lower E/A, lower e′, higher E/e′, and longer IVRT compared to controls. Though none met criteria for Grade I diastolic dysfunction, Z-scores for e′, E/e′, and IVRT were abnormal in 30%, 25%, and 6% of SLE cases, respectively. Greater disease activity was associated with lower septal e′ (p < 0.01), higher E/e′ (p = 0.02), and longer IVRT (p < 0.01). Children with incident SLE have worse diastolic indices at diagnosis compared to peers without SLE, independent of blood pressure and prior to significant prednisone exposure. Longitudinal studies will determine whether diastolic dysfunction develops in this population over time. [ABSTRACT FROM AUTHOR]

Background: Childhood-onset systemic erythematosus lupus (cSLE) is characterized by more severe disease, widespread organ involvement and higher mortality compared to adult-onset SLE. However, cSLE is largely underfunded to carry out necessary research to advance the field. Few commonly used SLE medications have been studied in children, and important knowledge gaps exist concerning epidemiology, genetics, pathophysiology and optimal treatments for cSLE. Methods: In order to assess highest cSLE research priority areas, the Lupus Foundation of America (LFA) and Childhood Arthritis and Rheumatology Research Alliance (CARRA) administered a cSLE research prioritization survey to pediatric rheumatologists, dermatologists and nephrologists with expertise in lupus. Members of LFA and CARRA's SLE Committee identified a list of cSLE research domains and developed a 17-item tiered, web-based survey asking respondents to categorize the research domains into high, medium, or low priority areas. For domains identified as high priority, respondents ranked research topics within that category. For example, for the domain of nephritis, respondents ranked importance of: epidemiology, biomarkers, long-term outcomes, quality improvement, etc. The survey was distributed to members of CARRA, Midwestern Pediatric Nephrology Consortium (MWPNC) and Pediatric Dermatology Research Alliance (PeDRA) Connective Tissue Disease group. Results: The overall response rate was 256/752 (34%). The highest prioritized research domains were: nephritis, clinical trials, biomarkers, neuropsychiatric disease and refractory skin disease. Notably, nephritis, clinical trials and biomarkers were ranked in the top five by all groups. Within each research domain, all groups showed agreement in identifying the following as important focus areas: determining best treatments, biomarkers/pathophysiology, drug discovery/novel treatments, understanding long term outcomes, and refining provider reported quality measures. Conclusion: This survey identified the highest cSLE research priorities among leading rheumatology, dermatology and nephrology clinicians and investigators engaged in care of children with lupus. There is a strong need for multidisciplinary collaboration moving forward, which was indicated as highly important among stakeholders involved in the survey. These survey results should be used as a roadmap to guide funding and specific research programs in cSLE to address urgent, unmet needs among this population. [ABSTRACT FROM AUTHOR]

- Abstract
The overexpression of MYC genes is frequently found in many human cancers, including adult and pediatric malignant brain tumors. Targeting MYC genes continues to be challenging due to their undruggable nature. Using our prediction algorithm, the nine-amino-acid activation domain (9aaTAD) has been identified in all four Yamanaka factors, including c-Myc. The predicted activation function was experimentally demonstrated for all these short peptides in transactivation assay. We generated a set of c-Myc constructs (1-108, 69-108 and 98-108) in the N-terminal regions and tested their ability to initiate transcription in one hybrid assay. The presence and absence of 9aaTAD (region 100-108) in the constructs strongly correlated with their activation functions (5-, 3- and 67-times respectively). Surprisingly, we observed co-activation function of the myc region 69-103, called here acetyl-TAD, previously described by Faiola et al. (Mol Cell Biol 25:10220-10234, 2005) and characterized in this study as a new domain collaborating with the 9aaTAD. We discovered strong interactions on a nanomolar scale between the Myc-9aaTAD activation domains and the KIX domain of CBP coactivator. We showed conservation of the 9aaTADs in the MYC family. In summary for the c-Myc oncogene, the acetyl-TAD and the 9aaTAD domains jointly mediated activation function. The c-Myc protein is largely intrinsically disordered and therefore difficult to target with small-molecule inhibitors. For the c-Myc driven tumors, the strong c-Myc interaction with the KIX domain represents a promising druggable target., Competing Interests: Declarations Ethics approval and consent to participate Not applicable.

- Abstract
Background: Mental health (MH) conditions are prevalent in adolescents with childhood-onset SLE (cSLE). Early identification is crucial in preventing poor patient outcomes; however, MH screening rates remain low., Local Problem: From July 2021-January 2022, only 15% of adolescents in a paediatric tertiary care cSLE clinic were being screened for depression and anxiety. By November 2023, we aimed to increase the percentage of patients with cSLE (≥12-18 years) screened for depression (Patient Health Questionnaire: PHQ-9) and anxiety (Generalised Anxiety Disorder-7: GAD-7) from 15% to 80%., Methods: This quality improvement project employed the Model for Improvement framework. Stakeholders included the clinic team, patients and families, and MH providers. Statistical process control charts were used to analyse the outcome measure for percentage of screened patients with cSLE. Patient and caregiver satisfaction surveys were conducted at baseline and after screening as a balancing measure., Interventions: MH screening workflow with a referral algorithm was developed with stakeholders. Additional interventions included two MH training workshops for healthcare providers and a preclinic reminder of eligible patients for screening., Results: Over 21 months, 146 patients with cSLE completed 270 MH screens, increasing the screening rate from 15%, peaking at 100%, to a median of 56%. Sixty-six individuals (45%) reported symptoms of depression and/or anxiety on their initial screen. Of 270 screens, 44 individuals (17%) reported moderate to severe symptoms meeting the screening workflow criteria for referral to a MH service; 10% of patients screened were referred and seen by the MH service within 2-12 weeks. Patients and caregivers reported satisfaction with the MH screening process and quality of MH follow-up., Conclusion: Despite not sustainably meeting the target, MH screening rates increased in the cSLE clinic by nearly fourfold, demonstrating feasibility and acceptability. Patients expressed satisfaction with their mental health follow-up, emphasising its importance in their care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objectives: Childhood-onset systemic lupus erythematosus (cSLE), representing 15%-20% of individuals with SLE, has been difficult to study globally due to differences between registries. This initiative, supported by Childhood Arthritis Rheumatology Research Alliance (CARRA) and Paediatric Rheumatology European Society (PReS), aims to create Core and Expanded cSLE Datasets to standardise and enhance research worldwide., Methods: 21 international cSLE experts and 4 patients participated in a Delphi process (questionnaires, 2 topic-specific focus groups and 3 virtual consensus meetings) to create 2 standardised cSLE datasets. The Core cSLE Dataset was designed to include data essential to meaningful clinical research across many settings. The Expanded cSLE Dataset was designed for centres able to consistently collect data to address broader research questions. Final data items for the Core and Expanded datasets were determined by consensus defined as >80% agreement) using an adapted nominal group technique and voting., Results: The resulting Core cSLE Dataset contains 46 items, including demographics, clinical features, laboratory results, medications and significant adverse events. The Expanded cSLE Dataset adds 26 additional items and includes patient-reported outcomes. Consensus was also achieved regarding the frequency and time points for data collection: baseline, quarterly follow-up visits, annually and flare visits., Conclusion: Standardised Core and Expanded cSLE Datasets for registry-based international cSLE research were defined through the consensus of global experts and patient/caregiver representatives, endorsed by CARRA and PReS. These datasets incorporate disease-specific and patient-specific features, optimised for diverse settings to facilitate international collaborative research for children and adolescents with SLE worldwide., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objective: Differential disease control may contribute to racial disparities in outcomes of childhood-onset systemic lupus erythematosus (cSLE). We evaluated associations of race and individual- or neighborhood-level social determinants of health (SDoH) with achievement of low lupus disease activity state (LLDAS), a clinically relevant treatment target., Methods: In this cSLE cohort study using the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry, the primary exposure was self-reported race and ethnicity, and collected SDoH included insurance status and area deprivation index (ADI). Outcomes included LLDAS, disease activity, and time-averaged prednisone exposure. Associations among race and ethnicity, SDoH, and disease activity were estimated with multivariable regression models, adjusting for disease-related and demographic factors., Results: Among 540 children with cSLE, 27% identified as Black, 25% identified as White, 23% identified as Latino/a, 11% identified as Asian, 9% identified as more than one race, and 5% identified as other. More Black children (41%) lived in neighborhoods of highest ADI compared to White children (16%). Black race was associated with lower LLDAS achievement (adjusted odds ratio 0.56, 95% confidence interval [CI] 0.38-0.82) and higher disease activity (adjusted β 0.94, 95% CI 0.11-1.78). The highest ADI was not associated with lower LLDAS achievement on adjustment for renal disease and insurance. However, renal disease was found to be a significant mediator (P = 0.04) of the association between ADI and prednisone exposure., Conclusions: Children with cSLE who identified as Black are less likely to achieve LLDAS and have a higher disease activity. Living in areas of higher ADI may relate to renal disease and subsequent prednisone exposure. Strategies to address root causes will be important to design interventions mitigating cSLE racial disparities., (© 2024 The Author(s).

- Abstract
Background: Cognitive dysfunction (CD) is highly prevalent in systemic lupus erythematosus (SLE), yet the underlying mechanisms are poorly understood. Neuroimaging utilising advanced MRI metrics may yield mechanistic insights. We conducted a systematic review of neuroimaging studies to investigate the relationship between structural and diffusion MRI metrics and CD in SLE., Methods: We systematically searched several databases between January 2000 and October 2023 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Retrospective and prospective studies were screened for search criteria keywords (including structural or diffusion MRI, cognitive function and SLE) to identify peer-reviewed articles reporting advanced structural MRI metrics and evaluating CD in human patients with SLE., Results: Eighteen studies (8 structural MRI, 9 diffusion MRI and 1 with both modalities) were included; sample sizes ranged from 11 to 120 participants with SLE. Neurocognitive assessments and neuroimaging techniques, parameters and processing differed across articles. The most frequently affected cognitive domains were memory, psychomotor speed and attention; while abnormal structural and/or diffusion MRI metrics were found more consistently in the hippocampus, corpus callosum and frontal cortex of patients with SLE, with and without clinically diagnosed central nervous system involvement., Conclusion: Advanced structural MRI analysis can identify total and regional brain abnormalities associated with CD in patients with SLE, with potential to enhance clinical assessment. Future collaborative, longitudinal studies of neuroimaging in SLE are needed to better characterise CD, with focus on harmonised neurocognitive assessments, neuroimaging acquisitions and postprocessing analyses and improved clinical characterisation of SLE cohorts., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objective: Neonatal lupus erythematosus (NLE) is a passively acquired autoimmune disease in infants born to anti-Ro and/or anti-La autoantibody-positive mothers. Genetics may affect NLE risk. We analyzed the genetics of infants and anti-Ro antibody-positive mothers, with NLE and NLE-specific manifestations., Methods: Infants and mothers from a tertiary care clinic underwent genotyping on the Global Screening Array. We created additive non-HLA and HLA polygenic risk scores (PRS) for systemic lupus erythematosus (SLE), from one of the largest genome-wide association studies. Outcomes were any NLE manifestations, cardiac NLE, and cutaneous NLE. We tested the association between SLE-PRS in the infant, mother, and the PRS difference between the mother and infant with NLE outcomes, in logistic regression and generalized linear mixed models (Bonferroni P < 0.02). We also performed HLA-wide analyses for the outcomes ( P < 5.00 × 10
-8 )., Results: The study included 332 infants, 270 anti-Ro antibody-positive mothers, and 253 mother-infant pairs. A large proportion of mothers (40.4%) and infants (41.3%) were European, and 50% of infants were female. More than half of the infants had NLE (53%), including 7.2% with cardiac NLE and 11.7% with cutaneous NLE. We did not identify significant associations between infant PRS, maternal PRS, or maternal-infant PRS difference and any NLE outcomes. HLA-wide analyses did not identify NLE risk alleles., Conclusion: In a multiethnic cohort of infants and anti-Ro antibody-positive mothers, we did not identify a significant association between SLE genetics and risk of NLE outcomes.- Published

- Abstract
Objective: To determine if self-reported fatigue, anxiety, depression, cognitive difficulties, health-related quality of life, disease activity scores and neuropsychological battery (NB) cluster into distinct groups in patients with SLE based on symptom intensity and if they change at 1-year follow-up., Methods: This is a retrospective analysis of consecutive consenting patients, followed at a single centre. Patients completed a comprehensive NB, the Beck Anxiety Inventory, Beck Depression Inventory, Fatigue Severity Scale, Short-Form Health Survey Physical Component Summary and Mental Component Summary scores and the Perceived Deficits Questionnaire. Disease activity was assessed by Systemic Lupus Erythematosus Disease Activity Index 2000. Ward's method was used for clustering and principal component analysis was used to visualise the number of clusters. Stability at 1 year was assessed with kappa statistic., Results: Among 142 patients, three clusters were found: cluster 1 had mild symptom intensity, cluster 2 had moderate symptom intensity and cluster 3 had severe symptom intensity. At 1-year follow-up, 49% of patients remained in their baseline cluster. The mild cluster had the highest stability (77% of patients stayed in the same cluster), followed by the severe cluster (51%), and moderate cluster had the lowest stability (3%). A minority of patients from mild cluster moved to severe cluster (19%). In severe cluster, a larger number moved to moderate cluster (40%) and fewer to mild cluster (9%)., Conclusion: Three distinct clusters of symptom intensity were documented in patients with SLE in association with cognitive function. There was a lower tendency for patients in the mild and severe clusters to move but not moderate cluster over the course of a year. This may demonstrate an opportunity for intervention to have moderate cluster patients move to mild cluster instead of moving to severe cluster. Further studies are necessary to assess factors that affect movement into moderate cluster., Competing Interests: Competing interests: AG reports consulting fees from AbbVie.

- Abstract
Background: Depressive and anxiety symptoms are common in childhood-onset systemic lupus erythematosus (cSLE), yet their etiology and course remain unclear. We investigated the frequency of depressive and anxiety symptoms longitudinally in youth with cSLE, and associated socio-demographic and disease factors., Methods: Participants 8-18 years with cSLE completed baseline measures [demographic questionnaire, Center for Epidemiologic Studies Depression Scale for Children (CES-DC), Screen for Childhood Anxiety Related Disorders (SCARED), and psychiatric interview] and follow-up measures (CES-DC and SCARED) > 6 months later. Prevalence of clinically significant depressive (score >15 on CES-DC) or anxiety symptoms (score ≥ 25 on SCARED) was calculated at baseline and follow-up. Baseline psychiatric interview diagnoses were tabulated. Relationships between socio-demographics (neighborhood-level material deprivation, ethnic concentration, adverse childhood event history, psychiatric condition in a first-degree relative), disease-related factors (disease duration, major organ disease, disease activity, glucocorticoid use, comorbid medical condition) and baseline depressive and anxiety scores, were examined in linear regression models. Factors with univariate associations with p < 0.2 were included in multivariable adjusted models., Results: At baseline, of 51 participants with a mean disease duration of 4.3 years (SD 2.7), 35% ( n = 18) and 35% ( n = 18) had clinically significant depressive and anxiety symptoms, respectively. Anxiety disorder was diagnosed by psychiatric interview in 14% ( n = 7), depressive disorders in 6% ( n = 3), and post-traumatic stress disorder in 4% ( n = 2). Adverse childhood events and first-degree relative with psychiatric condition were present in 40% ( n = 20) and 37% ( n = 18), respectively. In multivariable regression analysis, baseline depressive symptoms were positively correlated with neighbourhood-level material deprivation (β = 4.2, 95% CI [1.0, 7.3], p = 0.01) and psychiatric condition in a first-degree relative (β = 7.3, 95% CI [2.2, 12.4], p = 0.006). No associations were found between baseline anxiety scores and patient factors. At a median follow-up of 13.5 months (IQR 10.5, 18) for CES-DC ( n = 34) and SCARED ( n = 44), depressive and anxiety symptoms were persistent (18%, n = 6; 16%, n = 7), and newly present (24%, n = 8; 16% n = 7) at follow-up., Conclusion: In this sample, depressive and anxiety symptoms were prevalent and persistent. Depressive symptoms correlated with neighborhood-level material deprivation, and family psychiatric history. These findings support routine psychosocial assessment in cSLE, and provision of appropriate resources., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objective: Our objective was to characterize adolescent health and psychosocial issues in patients with childhood-onset systemic lupus erythematosus (cSLE) and evaluate demographic and disease characteristics associated with adolescent health., Methods: We retrospectively examined adolescents aged 12 to 18 years with cSLE seen at the Hospital for Sick Children meeting the American College of Rheumatology/Systemic Lupus International Collaborating Clinics classification criteria, assessed by adolescent medicine in the cSLE clinic between 2018 and 2020. Adolescent health issues were characterized using the Home, Education/Employment, Activities, Diet/Drugs, Sexuality, Suicide/mood (HEADDSS) framework. Issues were classified as presenting and/or identified; adolescent health burden was tabulated as the number of distinct adolescent issues per patient. Multiple Poisson regression models examined associations between patient and disease characteristics (age, sex, material deprivation, disease activity, disease damage, and high-dose glucocorticoid exposure) and adolescent health issues., Results: A total of 108 (60%) of 181 adolescents with cSLE were seen by adolescent medicine, with a median of 2 (interquartile range [IQR] 1-3) visits and a median of 2 (IQR 1-5) adolescent health issues during the study period. Common issues were mood (presenting in 21% vs identified in 50%), sleep (27% vs 2%), school and education (26% vs 1%), and nonadherence (23% vs 8%). Psychoeducation was provided by adolescent medicine to 54% of patients. High-dose glucocorticoids (risk ratio [RR] 1.82, 95% confidence interval [CI] 1.41-2.35, P < 0.001), material deprivation (RR 1.17, 95% CI 1.04-1.30, P = 0.007), and lower SLE Disease Activity Index scores (RR 0.95, 95% CI 0.92-0.98, P = 0.004) were associated with higher adolescent health burden., Conclusion: Adolescents with cSLE experience many adolescent issues, especially low mood. High-dose glucocorticoids and social marginalization are associated with greater adolescent health burden. This study highlights the importance of addressing adolescent health needs as part of routine care., (© 2024 American College of Rheumatology.)

- Abstract
Background: Pediatric rheumatology is a term that encompasses over 80 conditions affecting different organs and systems. Children and young people with rheumatological chronic conditions are known to have high levels of mental health problems and therefore are at risk of poor health outcomes. Clinical psychologists can help children and young people manage the daily difficulties of living with one of these conditions; however, there are insufficient pediatric psychologists in the United Kingdom. We urgently need to consider other ways of providing early, essential support to improve their current well-being. One way of doing this is to empower parents and caregivers to have more of the answers that their children and young people need to support them further between their hospital appointments., Objective: The objective of this co-designed proof-of-concept study is to design, develop, and test a chatbot intervention to support parents and caregivers of children and young people with rheumatological conditions., Methods: This study will explore the needs and views of children and young people with rheumatological conditions, their siblings, parents, and caregivers, as well as health care professionals working in pediatric rheumatology. We will ask approximately 100 participants in focus groups where they think the gaps are in current clinical care and what ideas they have for improving upon them. Creative experience-based co-design workshops will then decide upon top priorities to develop further while informing the appearance, functionality, and practical delivery of a chatbot intervention. Upon completion of a minimum viable product, approximately 100 parents and caregivers will user-test the chatbot intervention in an iterative sprint methodology to determine its worth as a mechanism for support for parents., Results: A total of 73 children, young people, parents, caregivers, and health care professionals have so far been enrolled in the study, which began in November 2023. The anticipated completion date of the study is April 2026. The data analysis is expected to be completed in January 2026, with the results being published in April 2026., Conclusions: This study will provide evidence on the accessibility, acceptability, and usability of a chatbot intervention for parents and caregivers of children and young people with rheumatological conditions. If proven useful, it could lead to a future efficacy trial of one of the first chatbot interventions to provide targeted and user-suggested support for parents and caregivers of children with chronic health conditions in health care services. This study is unique in that it will detail the needs and wants of children, young people, siblings, parents, and caregivers to improve the current support given to families living with pediatric rheumatological conditions. It will be conducted across the whole of the United Kingdom for all pediatric rheumatological conditions at all stages of the disease trajectory., International Registered Report Identifier (irrid): DERR1-10.2196/57238., (©Polly Livermore, Klaudia Kupiec, Lucy R Wedderburn, Andrea Knight, Ameenat L Solebo, Roz Shafran, Glenn Robert, N J Sebire, Faith Gibson, IMPACT Steering Group.

- Abstract
Objective: The prevalence and types of psychosocial complications of juvenile localized scleroderma (JLS), also known as morphea, an inflammatory and sclerosing disease involving the skin, fascia, muscle, and bone, are poorly understood., Methods: We performed a systematic review of literature published between 2000 and 2020 in PubMed, EMBASE, the Cochrane Skin Group Specialized Register, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature using the search terms "scleroderma, localized," "Morphea," "anxiety," "depression," "resilience," "social stigma," "quality of life," "mood," or "stress" and limited the search to pediatric patients and English language. Patient demographics, characteristics of JLS, and comorbidities were extracted. The outcomes included measures of health-related quality of life (HRQoL), psychosocial functioning, evaluation of self-perception, and the treatment burden of the study population. The protocol was registered with PROSPERO (CRD42021257124). Thematic synthesis generated descriptive analysis., Results: Thirteen studies fulfilled the inclusion criteria: three retrospective cohort studies, two prospective cohort studies, and eight cross-sectional studies. A total of 690 pediatric patients with JLS were included (n = 484 with linear scleroderma). Six studies used the Children's Dermatology Life Quality Index, reporting little to no effect on HRQoL. One study used the Health-Related Quality of Life in Children and Adolescents Questionnaire and did not find differences between children with JLS or atopic dermatitis and healthy controls. One study used a self-perception questionnaire that showed normal self-worth of patients with JLS. Two studies used focus groups, both reporting elevated levels of stress, decreased self-worth, "feeling different," and bullying/teasing in patients with JLS. These emotions were associated with skin symptoms (pain, itch, and tightness), physical limitations, and treatment burden., Conclusion: Overall, quantitative studies did not report a statistically significant impairment in HRQoL in JLS. However, qualitative studies (focus groups) reported significant psychosocial impacts related to JLS. There is a need to develop a JLS-specific tool for the HRQoL evaluation of this population., (© 2023 The Authors.

- Abstract
Psychological and emotional well-being are critical aspects of overall health for individuals with chronic rheumatologic conditions. Mental health-related literature, however, predominantly focuses on systemic lupus erythematosus or rheumatoid arthritis, with limited emphasis on idiopathic inflammatory myopathies (IIMs). High proportions of those with juvenile myositis report psychological distress at levels warranting mental health referral. Adults with dermatomyositis diagnosed with depression or anxiety do not receive adequate mental health care. Mental health symptoms in those with IIMs are associated with worse health-related quality of life, medication adherence, and disease outcomes. Despite demonstrated high rates of mental health burden, access to mental health care remains severely lacking.Data related to mental health burden is limited by small sample size, limited generalisability, variable methods of assessment, and inconsistent diagnosis codes to define mental health conditions. Additional research is needed to validate current screening tools in myositis populations. Other relevant measurable factors include disease severity, non-health- and health-related trauma exposure, loneliness, isolation, loss of control, sleep difficulties, fatigue, pain, self-esteem, body image, sexual health, and health inequities. Studiesare needed investigating the efficacy of therapeutic and pharmacologic interventions among patients with myositis who experience depression and anxiety. Currently, knowledge and resources are limited around mental health burden and potential intervention for those living with IIMs. The Myositis International Health & Research Collaborative Alliance (MIHRA) Psychological Impact Scientific Working Group offers a preliminary road map to characterise and prioritise the work ahead to understand baseline mental health burden and compare avenues for intervention.

- Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The complex relationships between race and ethnicity and social determinants of health (SDOH) in influencing SLE and its course are increasingly appreciated. Multiple SDOH have been strongly associated with lupus incidence and outcomes and contribute to health disparities in lupus. Measures of socioeconomic status, including economic instability, poverty, unemployment, and food insecurity, as well as features of the neighborhood and built environment, including lack of safe and affordable housing, crime, stress, racial segregation, and discrimination, are associated with race and ethnicity in the US and are risk factors for poor outcomes in lupus. In this scientific statement, we aimed to summarize current evidence on the role of SDOH in relation to racial and ethnic disparities in SLE and SLE outcomes, primarily as experienced in the U.S. Lupus Foundation of America's Health Disparities Advisory Panel, comprising 10 health disparity experts, including academic researchers and patients, who met 12 times over the course of 18 months in assembling and reviewing the data for this study. Sources included articles published from 2011 to 2023 in PubMed, Centers for Disease Control and Prevention data, and bibliographies and recommendations. Search terms included lupus, race, ethnicity, and SDOH domains. Data were extracted and synthesized into this scientific statement. Poorer neighborhoods correlate with increased damage, reduced care, and stress-induced lupus flares. Large disparities in health care affordability, accessibility, and acceptability exist in the US, varying by region, insurance status, and racial and minority groups. Preliminary interventions targeted social support, depression, and shared-decision-making, but more research and intervention implementation and evaluation are needed. Disparities in lupus across racial and ethnic groups in the US are driven by SDOH, some of which are more easily remediable than others. A multidimensional and multidisciplinary approach involving various stakeholder groups is needed to address these complex challenges, address these diminish disparities, and improve outcomes., (© 2023 The Authors.

- Abstract
The nine-amino-acid transactivation domains (9aaTAD) was identified in numerous transcription factors including Gal4, p53, E2A, MLL, c-Myc, N-Myc, and also in SP, KLF, and SOX families. Most of the 9aaTAD domains interact with the KIX domain of transcription mediators MED15 and CBP to activate transcription. The NFkB activation domain occupied the same position on the KIX domain as the 9aaTADs of MLL, E2A, and p53. Binding of the KIX domain is established by the two-point interaction involving 9aaTAD positions p3-4 and p6-7. The NFkB primary binding region (positions p3-4) is almost identical with MLL and E2A, but secondary NFkB binding region differs by the position and engages the distal NFkB region p10-11. Thus, the NFkB activation domain is five amino acids longer than the other 9aaTADs. The NFkB activation domain includes an additional region, which we called the Omichinski Insert extending activation domain length to 14 amino acids. By deletion, we demonstrated that Omichinski Insert is an entirely non-essential part of NFkB activation domain. In summary, we recognized the NFkB activation domain as prolonged 9aaTAD conserved in evolution from humans to amphibians., (© 2023 The Author(s).

- Abstract
Recent studies have underscored the importance of gamma-delta (γδ) T cells in mediating potent MHC-unrestricted cytotoxicity in numerous malignancies. Here, we analyzed Vδ1 and Vδ2 γδ T cell subsets in newly diagnosed chronic myeloid leukemia (CML) patients (n = 40) who had initiated tyrosine kinase inhibitor (TKI) therapy including imatinib (n = 22), nilotinib (n = 14) and dasatinib (n = 4). Patient peripheral blood samples were analyzed at diagnosis and monitored prospectively at 3, 6, 12 and 18 months post-TKI. γδ T cells isolated from healthy donors and CML patients were used against K562, LAMA-84 and KYO-1 cell lines and against primary CML cells in cytotoxicity assays. We found large expansions of Vδ1 and Vδ2 T cells in patients at diagnosis compared to age-matched healthy donors (n = 40) (p < 0.0001). The γδ T cell reconstitution in patients on imatinib and also on nilotinib showed significant reductions of Vδ1 T cell and Vδ2 T cell absolute counts at 3 months compared to diagnosis. Importantly, Vδ1 and Vδ2 T absolute cell counts remained at normal levels from 3 months throughout the follow-up. Next, we observed susceptibility to specific lysis of primary CML tumor cells by Vδ1 T cells from healthy donors. Furthermore, we determined inherent cytotoxic reactivity by autologous patients' Vδ1 T lymphocytes against primary CML tumor cells. Finally, the TCR clonality profiles showed in CML patients mostly polyclonal repertoires regardless of the TKI. Our results provide further evidence into γδ T cell antileukemia immunity in CML that might be beneficial for long-term disease control and treatment outcome., (© 2022. The Author(s).)

- Abstract
Previously, the Nine amino acid TransActivation Domain (9aaTAD) was identified in the Gal4 region 862-870 (DDVYNYLFD). Here, we identified 9aaTADs in the distal Gal4 orthologs by our prediction algorithm and found their conservation in the family. The 9aaTAD function as strong activators was demonstrated. We identified adjacent Gal4 region 871-811 (DEDTPPNPKKE) as a natural 9aaTAD inhibitory domain located at the extreme Gal4 terminus. Moreover, we identified conserved Gal4 region 172-185 (FDWSEEDDMSDGLP), which was capable to reverse the 9aaTAD inhibition. In conclusion, our results uncover the existence of the cryptic inhibitory domains, which need to be carefully implemented in all functional studies with transcription factors to avoid incorrect conclusions., (Copyright © 2022 Elsevier B.V. and Société Française de Biochimie et Biologie Moléculaire (SFBBM).

- Abstract
Background: Mental health disorders are common in youth with rheumatological disease yet optimal intervention strategies are understudied in this population. We examined patient and parent perspectives on mental health intervention for youth with rheumatological disease., Methods: We conducted a mixed methods cross-sectional study, via anonymous online survey, developed by researchers together with patient/parent partners, to quantitatively and qualitatively examine youth experiences with mental health services and resources in North America. Patients ages 14-24 years with juvenile idiopathic arthritis, juvenile dermatomyositis, or systemic lupus erythematous, and parents of patients ages 8-24 with these diseases were eligible (not required to participate in pairs). Participants self-reported mental health problems (categorized into clinician-diagnosed disorders vs self-diagnosed symptoms) and treatments (e.g. therapy, medications) received for the youth. Multivariate linear regression models compared patient and parent mean Likert ratings for level of: i) comfort with mental health providers, and ii) barriers to seeking mental health services, adjusting for potential confounders (patient age, gender, disease duration, and patient/parent visual analog score for disease-related health). Participants indicated usefulness of mental health resources; text responses describing these experiences were analyzed by qualitative description., Results: Participants included 123 patients and 324 parents. Patients reported clinician-diagnosed anxiety (39%) and depression (35%); another 27 and 18% endorsed self-diagnosed symptoms of these disorders, respectively. 80% of patients with clinician-diagnosed disorders reported receiving treatment, while 11% of those with self-diagnosed symptoms reported any treatment. Patients were less comfortable than parents with all mental health providers. The top two barriers to treatment for patients and parents were concerns about mental health providers not understanding the rheumatological disease, and inadequate insurance coverage. Over 60% had used patient mental health resources, and over 60% of these participants found them to be helpful, although text responses identified a desire for resources tailored to patients with rheumatological disease., Conclusion: Self-reported mental health problems are prevalent for youth in this sample with rheumatological disease, and obstacles to mental health treatment include disease-related and logistic factors. Strategies are needed to improve acceptance and accessibility of mental health intervention, including routine mental health screening and availability of disease-specific mental health resources.

- Abstract
Objective: Youth with systemic lupus erythematosus (SLE) transferring from pediatric to adult care are at risk for poor outcomes. We describe patterns of rheumatology/nephrology care and changes in healthcare use and medication adherence during transfer., Methods: We identified youth ages 15-25 with SLE using US private insurance claims from Optum's deidentified Clinformatics Data Mart. Rheumatology/nephrology visit patterns were categorized as (1) unilateral transfers to adult care within 12 months, (2) overlapping pediatric and adult visits, (3) lost to followup, or (4) continuing pediatric care. We used negative binomial regression and paired t tests to estimate changes in healthcare use and medication possession ratios (MPR) after the last pediatric (index) visit. We compared MPR between youth who transferred and age-matched peers continuing pediatric care., Results: Of the 184 youth transferred out of pediatric care, 41.8% transferred unilaterally, 31.5% had overlapping visits over a median of 12 months before final transfer, and 26.6% were lost to followup. We matched 107 youth continuing pediatric care. Overall, ambulatory care use decreased among those lost to followup. Acute care use decreased across all groups. MPR after the index date were lower in youth lost to followup (mean 0.24) compared to peers in pediatric care (mean 0.57, p < 0.001)., Conclusion: Youth with SLE with continuous private insurance coverage do not use more acute care after transfer to adult care. However, a substantial proportion fail to see adult subspecialists within 12 months and have worse medication adherence, placing them at higher risk for adverse outcomes.

- Abstract
Background: Loss of the normal nocturnal decline in blood pressure (BP), known as non-dipping, is a potential measure of cardiovascular risk identified by ambulatory blood pressure monitoring (ABPM). We sought to determine whether non-dipping is a useful marker of abnormal vascular function and subclinical atherosclerosis in pediatric-onset systemic lupus erythematosus (pSLE)., Methods: Twenty subjects 9-19 years of age with pSLE underwent ABPM, peripheral endothelial function testing, carotid-femoral pulse wave velocity/analysis for aortic stiffness, and carotid intima-media thickness. We assessed the prevalence of non-dipping and other ABPM abnormalities. Pearson or Spearman rank correlation tests were used to evaluate relationships between nocturnal BP dipping, BP load (% of abnormally elevated BPs over 24-h), and vascular outcome measures., Results: The majority (75%) of subjects had inactive disease, with mean disease duration of 3.2 years (± 2.1). The prevalence of non-dipping was 50%, which occurred even in the absence of nocturnal or daytime hypertension. Reduced diastolic BP dipping was associated with poorer endothelial function (r 0.5, p = 0.04). Intima-media thickness was significantly greater in subjects with non-dipping (mean standard deviation score of 3.0 vs 1.6, p = 0.02). In contrast, higher systolic and diastolic BP load were associated with increased aortic stiffness (ρ 0.6, p = 0.01 and ρ 0.7, p < 0.01, respectively), but not with endothelial function or intima-media thickness., Conclusion: In a pSLE cohort with low disease activity, isolated nocturnal BP non-dipping is prevalent and associated with endothelial dysfunction and atherosclerotic changes. In addition to hypertension assessment, ABPM has a promising role in risk stratification and understanding heterogeneous mechanisms of cardiovascular disease in pSLE.

- Abstract
Objective: To compare major depression risk among young adults with juvenile-onset and adult-onset systemic lupus erythematosus (SLE), and to determine demographic and health-related predictors of depression., Methods: Young adults with SLE ages 18-45 years (n = 546) in the Lupus Outcomes Study completed annual telephone surveys from 2002-2015, including assessment of depression using the Center for Epidemiologic Studies Depression Scale (CES-D), and self-report measures of sociodemographics and health characteristics. Juvenile-onset SLE was defined as age <18 years at diagnosis (n = 115). Repeated-measures analysis was performed to assess the risk for major depression (CES-D ≥24) at any point in study, and logistic regression was used to assess for recurrent (present on ≥2 assessments) major depression., Results: Major depression was experienced by 47% of the cohort at least once during the 12-year study period. In adjusted analyses, juvenile-onset SLE patients had an increased risk of having a major depressive episode (odds ratio [OR] 1.7 [95% confidence interval (95% CI) 1.0-2.7]) and recurrent episodes (OR 2.2 [95% CI 1.2-4.3]), compared to participants with adult-onset SLE. Older age, lower educational attainment, and physical function, higher disease activity, and a history of smoking were associated with an increased depression risk. Juvenile-onset SLE patients had a higher risk of major depression across all educational groups., Conclusion: Young adults with SLE, particularly those with juvenile-onset disease, are at high risk for major depression, which is associated with increased disease activity, poorer physical functioning, and lower educational attainment. Early depression intervention in young adults with SLE has the potential to improve both medical and psychosocial outcomes., (© 2017, American College of Rheumatology.)

- Abstract
Athletes undergoing intensive training schedules have chronic exposure to stress-induced hormones such as cortisol that can depress immune function. We compared the circulating levels of T cell receptor excision circles (TREC), a marker of recent thymic emigrants, as well as the levels of naïve and memory subsets in a group of elite endurance athletes and in controls. The athletes showed a reduction in absolute numbers of naïve T cells, particularly in CD4 T cells. In contrast, memory cells were increased. TREC levels in the athletes were significantly reduced compared to age-matched controls. Such changes resemble premature ageing of the T cell component of the immune system. Since thymic production of T cells naturally decline with age, these results raise the concern that prolonging high intensity exercise into the 4th decade of life may have deleterious consequences for athletes' health., (Copyright © 2014 Elsevier Inc.
