Association of methotrexate polyglutamates concentration with methotrexate efficacy and safety in patients with rheumatoid arthritis treated with predefined dose: results from the MIRACLE trial.

Objectives: The usefulness of methotrexate-polyglutamates (MTX-PGs) concentration for management of rheumatoid arthritis has been debated. We aimed to clarify the association of MTX-PGs concentration with efficacy and safety in MTX-naïve patients initiating MTX in a prospective interventional clinical trial.

Methods: The MIRACLE trial enrolled 300 MTX-naïve patients.

Gestational weight gain patterns as predictors of cesarean deliveries in women diagnosed with gestational diabetes mellitus.

Background: Obesity and excessive gestational weight gain (GWG) have been linked to an increased risk of cesarean section. However, existing literature primarily focuses on weight gain during individual trimesters, lacking a comprehensive assessment of GWG trajectories across all three trimesters. This study aimed to investigate the impact of pre-pregnancy BMI and changes in GWG trajectories from the first to the third trimester on cesarean section in women with confirmed gestational diabetes mellitus (GDM).

Association of Alcohol Use Disorder and Perioperative Complications and Adverse Events After Spinal Fusion Surgery During the In-hospital Period: An Analysis of the National Inpatient Sample (NIS) Database.

Objective: Alcohol use disorder carries major effects shown to limit social support, increase recovery times, and lead to a higher incidence of surgical complications. This retrospective cohort study investigated the influence of AUD on perioperative outcomes and adverse events after spinal fusions in the largest sample size to date and spanning 11 years.

Methods: Data for adult (>18 years old) patients who underwent a spinal fusion as their primary surgery were identified from the Nationwide Inpatient Sample (NIS) database for the years 2009-2020.

The AHR-NRF2-JDP2 gene battery: Ligand-induced AHR transcriptional activation.

Aryl hydrocarbon receptor (AHR) and nuclear factor-erythroid 2-related factor 2 (NRF2) can regulate a series of genes encoding the detoxifying phase I and II enzymes, via a signaling crosstalk known as the "AHR-NRF2 gene battery". The chromatin transcriptional regulator Jun dimerization protein 2 (JDP2) plays a central role in thetranscription of AHR gene in response to the phase I enzyme ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin. It forms a transcriptional complex with AHR-AHR nuclear translocator (ARNT) and NRF2-small musculoaponeurotic fibrosarcoma proteins (sMAF), which are then recruited to the respective cis-elements, such as dioxin response elements and antioxidant response elements, respectively, in the AHR promoter.
