Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares

The Astrophysical Journal
Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass ejections (CMEs) associated with filament/prominence eruptions, but ...

Sun-as-a-star Study of an X-class Solar Flare with Spectroscopic Observations of CHASE

The Astrophysical Journal
Sun-as-a-star spectroscopic characteristics of solar flares can be used as a benchmark for the detection and analysis of stellar flares. Here, we study the Sun-as-a-star properties of an X1.0 solar flare, using high-resolution spectroscopic data obtained

Efficacy of Telitacicept in Childhood‐Onset Systemic Lupus Erythematosus: A Prospective Multicenter Cohort Study With Inverse Probability of Treatment Weighting –Adjusted Comparison to a Historical Control Group Treated With Belimumab

Arthritis &Rheumatology, EarlyView.
Objective The therapeutic effects of telitacicept combined with standard of care (SoC) in childhood‐onset systemic lupus erythematosus (cSLE) remain unclear. This study aims to evaluate its efficacy in comparison with belimumab combined with SoC.

Modeling the UV/Optical Light Curve of Re-brightening Tidal Disruption Events

The Astrophysical Journal
In recent years, a new subclass of tidal disruption events (TDEs) has been reported in the literature. The light curve of these TDEs shows a re-brightening feature in the decline phase after the first peak, which then leads to a second flare.

Biomarkers of Lupus Nephritis Histopathology: Where Do We Stand?

Arthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is characterized by a variable disease course, necessitating continuous monitoring. There is an urgent need to identify noninvasive biomarkers. By reviewing and critically assessing the quality of existing studies on LN biomarkers correlating with histopathology, we here explore the challenges in promoting their use in ...

Serious Infections in Offspring Exposed to Tumor Necrosis Factor Inhibitors During Pregnancy: Comparison of Timing During Pregnancy and Placental Transfer Ability

Arthritis &Rheumatology, EarlyView.
Objective We evaluated serious infection risk in offspring exposed to tumor necrosis factor inhibitors (TNFi) in utero, separated by TNFi timing and placental transfer ability. Methods Using MarketScan (2011–2021), we identified offspring born to mothers with chronic inflammatory diseases.

QPEs from EMRI Debris Streams Impacting Accretion Disks in Galactic Nuclei

The Astrophysical Journal
Quasi-periodic eruption (QPE) sources in galactic nuclei are often associated with a stellar object orbiting a supermassive black hole with an hours to days period, which is brought in as an extreme mass-ratio inspiral (EMRI).

Defining Optimally Safe and Effective Blood Levels of Hydroxychloroquine in Lupus: An Important Step toward Precision Drug Monitoring

Arthritis &Rheumatology, Accepted Article.
Background Using hydroxychloroquine (HCQ) dose of 5 mg/kg/day in systemic lupus erythematosus (SLE) is associated with a higher risk of flares; HCQ blood level monitoring could be a better way to adjust HCQ dose. We studied the upper threshold for a reference range of HCQ levels to inform routine monitoring.

Decision tree analysis as a preliminary evidence‐based tool for identifying the syndrome of undifferentiated recurrent fever in children compared with hereditary recurrent fevers and periodic fever, aphthosis, pharyngitis and adenitis syndrome

Arthritis &Rheumatology, Accepted Article.
Objective To develop evidence‐based criteria to classify SURF patients. Methods 112 SURF patients followed in a single tertiary referral center were analyzed. Patients with genetically confirmed hereditary recurrent fever (HRF) or with periodic fever, aphthosis, pharyngitis and adenitis (PFAPA) syndrome already analyzed for the Eurofever classification
