Comparison of systemic lupus international collaborating clinics 2012 classification criteria and European league against rheumatism/American college of rheumatology 2019 classification criteria for early detection of childhood onset systemic lupus erythematosus (multi-center study).

Objective: To assess the performance of the new EULAR/ACR criteria, particularly for early detection of cSLE, in comparison to the SLICC criteria among the pediatric population in multiple centers in Saudi Arabia.

Methods: We conducted a retrospective study that enrolled pediatric patients up to the age of 14 years who've been diagnosed with SLE and followed in pediatric rheumatology clinics at 9 multi-tertiary hospitals in Saudi Arabia from 2010 to 2021 as a case group and were compared to a similar group of pediatric patients who've had defined rheumatological diseases other than SLE with a positive ANA titer (≥1:80) as controls. In total, 245 patients were included and distributed as 129 cases (diagnosed by expert pediatric rheumatologists) versus 116 patients in the control group.

Hydrogen Underground Storage in Silica-Clay Shales: Experimental and Density Functional Theory Investigation.

In the context of reducing the global emissions of greenhouse gases, hydrogen (H) has become an attractive alternative to substitute the current fossil fuels. However, its properties, seasonal fluctuations, and the lack of extended energy stability made it extremely difficult to be economically and safely stored for a long term in recent years. Therefore, this paper investigated the potential of shale gas reservoirs (rich and low clay-rich silica minerals) to store hydrogen upon demand.

Psychological characteristics of juvenile fibromyalgia syndrome.

Background: The aim of the study was to compare psychological characteristics of adolescent patients with juvenile fibromyalgia syndrome (JFM) with individuals suffering from chronic pain (CP) due to headache or joint pain in the lower limbs unrelated to oncological, inflammatory or autoimmune diseases.

Methods: The study was conducted on 37 patients aged 13-18 years old, monitored at the Pain Therapy Outpatient Clinic of the "Bambino Gesù" Pediatric Hospital in Rome. A total of 21 patients were suffering from CP (headache and recurrent arthralgia) and 16 from JFM, diagnosed according to the criteria of the American College of Rheumatology.
