Summary: Advances in pluripotent stem cell technology have led to the efficient and reproducible generation of hepatocyte-like cell spheroids in various sizes using microwell culture platforms. These spheroids show high expressions of hepatic marker genes, enhanced drug-metabolizing activity, and increased sensitivity to hepatotoxicants compared to traditional hepatocytes. This imaging-based toxicity screening system holds promise for predicting drug-induced hepatotoxicity in the early stages of drug discovery.

Summary: Phytochemicals have long been known for their therapeutic potential in autoimmune disorders such as rheumatoid arthritis, but their combination with DMARDs can increase the efficacy of treatment while reducing toxic side effects. Studies have shown promising results in experimental and clinical settings when combining phytochemicals with DMARDs, highlighting the importance of this approach in future RA therapy.

Summary: Methotrexate is associated with rare bone lesions that are often misdiagnosed as osteoporotic fractures. Early diagnosis is crucial for treatment and prevention of further osteopathology. This case highlights the importance of raising awareness and taking appropriate therapeutic measures, including discontinuing methotrexate.

Summary: Patients with psoriatic disease, especially psoriasis, are at a higher risk of developing liver disease outcomes compared to those with rheumatoid arthritis when receiving methotrexate. Meanwhile, patients with psoriatic arthritis also have an increased likelihood of developing mild liver disease and cirrhosis.

Summary: This study aimed to externally validate a revised Boolean remission criteria using a higher patient global assessment (PtGA) threshold and validate the provisionally endorsed index-based criteria. The results showed that using the higher PtGA threshold increased the proportion of patients classified as achieving remission under the "Boolean2.0" criteria, improved agreement with index-based criteria, and did not compromise predictive value for radiographic or functional outcomes. The study findings were endorsed by ACR and EULAR.

Summary: This manuscript reviews the importance of the combination drug regimen of methotrexate (MTX) and aceclofenac (ACL) in treating and managing rheumatoid arthritis (RA). The combination treatment can regulate immunological pathways and decrease inflammation associated with RA. It has been shown to regulate the signaling pathway controlled by NF-KB and FOXO1.

Summary: Hepatotoxicity or drug-induced liver injury (DILI) is a significant problem in drug development, leading to drug failure and regulatory measures. The development of a co-culture system involving hepatocytes and other cell types has been shown to enhance the understanding and prediction of iDILI. In this study, a co-culture system using HepG2 cells and THP-1-derived macrophages was established and used to evaluate the effects of model iDILI compounds on viability and oxidative stress induction.

Summary: This study investigates the pharmacokinetics of methotrexate polyglutamate (MTX-PG) accumulation in red blood cells (RBCs) and peripheral blood mononuclear cells (PBMCs) in patients with early rheumatoid arthritis (RA) after oral and subcutaneous MTX treatment. The results show that there are disparate pharmacokinetic profiles between PBMCs and RBCs, with higher accumulation of MTX-PG in PBMCs. The distribution profile of MTX-PG in PBMCs remains constant over 6 months, while in RBCs, the main PG-moiety changes from MTX-PG(1) to MTX-PG(3).

Summary: A porous silicon-based nanomedicine is developed to deliver an antirheumatic drug to inflamed synovium and degrade into bone-remodeling products. The nanomedicine shows immunomo-dulatory and antiresorptive effects, and effectively ameliorates the progression of rheumatoid arthritis in a mouse model.

Summary: The study found that TNFi survival did not depend on seropositivity status, but seropositive patients who received concomitant MTX had significantly longer median survival time. Additionally, the co-administration of prednisone in seropositive patients receiving TNFi was highly associated with TNFi discontinuation.

Summary: As a folate antagonist, methotrexate (MTX) has been widely used in clinics for treating various tumors and inflammatory diseases. However, the dosage and clearance of MTX vary between individuals, and it may cause life-threatening side effects at high doses. Therefore, a convenient and simple method for MTX sensing is highly demanded.

Summary: This study investigated the changes in gut microbiome of RA patients treated with HQT or LEF, revealing significant differences in gut microbiota between RA patients and healthy controls. The clinical efficacy of the two treatments was similar, but the response trends of RA-related clinical indices differed between the two treatment groups.
