BRD4 is an epigenome reader known to exert key roles at the interface between chromatin remodeling and transcriptional regulation, and is primarily known for its role in promoting gene expression. In selective contexts, however, BRD4 may work as negative regulator of transcription. Here, we reported that BRD4 binds several long noncoding RNAs (lncRNA). Among these, the lncRNA NEAT1 was found to interfere with BRD4 transcriptional activity. Mechanistically, lncNEAT1 forms a complex with BRD4 and WDR5 and maintains them in a low-activity state. Treatment with Bromodomains and Extraterminal (BET) inhibitor caused the lncRNA NEAT1 to dissociate from the BRD4/WDR5 complex, restored the acetyl-transferase capacity of BRD4, and restored the availability of WDR5 to promote histone trimethylation, thereby promoting BRD4/WDR5 transcriptional activity and activation of target gene expression. In addition, the lncRNA NEAT1 then became available to bind and to inhibit EZH2, cooperatively increasing transcriptional activation. IMPLICATIONS Our results revealed an epigenetic program that involves the interaction between the lncRNA NEAT1 and BRD4, functioning as a molecular switch between BRD4's activator and repressor chromatin complexes.
Approximately 15%-45% of patients with unruptured intracranial aneurysms have multiple intracranial aneurysms (MIAs). Determining which one is most likely to rupture is extremely important for treatment decision making for MIAs patients. This study aimed to develop and validate a nomogram to evaluate the per-aneurysm rupture risk of MIAs patients.

A total of 1671 IAs from 700 patients with MIAs were randomly dichotomised into derivation and validation sets. JNJ-7706621 Multivariate logistic regression analysis was used to select predictors and construct a nomogram model for aneurysm rupture risk assessment in the derivation set. The discriminative accuracy, calibration performance and clinical usefulness of this nomogram were assessed. We also developed a multivariate model for a subgroup of 158 subarachnoid haemorrhage (SAH) patients and compared its performance with the nomogram model.

Multivariate analyses identified seven variables that were significantly associated with IA rupture (history of SAH, alcohol consumption, female sex, aspect ratio >1.5, posterior circulation, irregular shape and bifurcation location). The clinical and morphological-based MIAs (CMB-MIAs) nomogram model showed good calibration and discrimination (derivation set area under the curve (AUC)=0.740 validation set AUC=0.772). Decision curve analysis demonstrated that the nomogram was clinically useful. Compared with the nomogram model, the AUC of multivariate model developed from SAH patients had lower value of 0.730.

This CMB-MIAs nomogram for MIAs rupture risk is the first to be developed and validated in a large multi-institutional cohort. This nomogram could be used in decision-making and risk stratification in MIAs patients.

SLE is a strong risk factor for premature cardiovascular (CV) disease and mortality. We investigated which factors could explain poor prognosis in SLE compared with controls.

Patients with SLE and population controls without history of clinical CV events who performed carotid ultrasound examination were recruited for this study. The outcome was incident CV event and death. Event-free survival rates were compared using Kaplan-Meier curves. Relative HR (95% CI) was used to estimate risk of outcome.

Patients (n=99, 87% female), aged 47 (13) years and with a disease duration of 12 (9) years, had mild disease at inclusion, Systemic Lupus Erythematosus Diseases Activity Index score of 3 (1-6) and Systemic Lupus International Collaborating Clinics (SLICC) Damage Index score of 0 (0-1). The controls (n=109, 91% female) were 49 (12) years old. Baseline carotid intima-media thickness (cIMT) did not differ between the groups, but plaques were more prevalent in patients (p=0.068). During 10.1 (9.8-10.2) years, 12 ptraditional CV risk factors, cIMT and presence of carotid plaque. SLICC, SLE-APS and subclinical atherosclerosis may indicate a group at risk of worse outcome in SLE.
In patients with mild SLE of more than 10 years duration, there is a threefold to fourfold increased risk of CV events and death compared with persons who do not have SLE with similar pattern of traditional CV risk factors, cIMT and presence of carotid plaque. SLICC, SLE-APS and subclinical atherosclerosis may indicate a group at risk of worse outcome in SLE.
The rheumatoid arthritis impact of disease (RAID) questionnaire comprises seven patient-important domains of disease impact (pain, function, fatigue, sleep disturbance, emotional well-being, physical well-being, coping). RAID was validated as a pooled-weighted score. Its seven individual items separately could provide a valuable tool in clinical practice to guide interventions targeting the patient's experience of the disease. The aim was to separately assess the psychometric properties of each of the seven numeric rating scale (NRS) of the RAID (RAID.7).

Post hoc analyses of data from the cross-sectional RAID study and from the Rainbow study, an open-label 12-week trial of etanercept in patients with RA. Construct validity of each NRS was assessed cross-sectionally in the RAID data set by Spearman's correlation with the respective external instrument of reference. Using the rainbow data set, we assessed reliability through intraclass correlation coefficient between the screening and the baseline visits and responsiveness (sensitivity to change) by standardised response mean between baseline and 12 weeks.

A total of 671 patients with RA with features of established disease were analysed, 563 and 108 from RAID and Rainbow, respectively. The NRS correlated moderately to strongly with the respective external instrument of reference (r=0.62-0.81). Reliability ranged from 0.64 (0.51-0.74) (pain) to 0.83 (0.76-0.88) (sleep disturbance) and responsiveness from 0.93 (0.73-1.13) (sleep disturbance) to 1.34 (1.01-1.64) (pain).

The separate use of the individual NRS of RAID (RAID.7) is valid, feasible, reliable and sensitive to change, representing an opportunity to improve the assessment and treatment of disease impact with minimal questionnaire burden.
