Introduction: Ozoralizumab (OZR) is a novel tumor necrosis factor (TNF) inhibitor that was launched in Japan for treating patients with rheumatoid arthritis (RA) who have had an inadequate response to existing therapies. This post-hoc analysis aimed to compare the efficacy of OZR administered without methotrexate (MTX) with placebo or OZR administration in combination with MTX.
Methods: We analyzed the OZR group (30 mg) in the NATSUZORA trial (non-MTX, open trial) (OZR group; n = 94) and the placebo group (MTX group; n = 75) and the 30-mg OZR group (OZR + MTX group; n = 152) in the OHZORA trial (combined MTX, double-blind trial), and the covariates were adjusted by propensity score matching.
PAX3-FOXO1, an oncogenic transcription factor, drives a particularly aggressive subtype of rhabdomyosarcoma (RMS) by enforcing gene expression programs that support malignant cell states. Here we show that PAX3-FOXO1 RMS cells exhibit altered pyrimidine metabolism and increased dependence on enzymes involved in pyrimidine synthesis, including dihydrofolate reductase (DHFR). Consequently, PAX3-FOXO1 cells display increased sensitivity to inhibition of DHFR by the chemotherapeutic drug methotrexate, and this dependence is rescued by provision of pyrimidine nucleotides.

: Cerebral intra-arterial chemotherapy (CIAC) has been demonstrated to achieve tumoricidal concentrations in cerebral tumour cells that are otherwise unachievable due to the presence of the blood-brain barrier. In this study, we sought to analyze the safety of CIAC in a cohort of patients treated at the Centre intégré universitaire de santé et de services sociaux de l'Estrie-Centre hospitalier universitaire de Sherbrooke (CIUSSS-CHUS). : Treatments consisted of monthly CIAC.

The autoantibodies against the NR1 subunit are well known in the pathomechanism of NMDAR encephalitis. The dysfunction of the NR2 subunit could be a critical factor in this neurological disorder due to its important role in the postsynaptic pathways that direct synaptic plasticity. We report a case of paraneoplastic anti-NMDAR encephalitis presented alongside very severe illness.

Desmoid-type fibromatosis (DTF) is a locally invasive tumor composed of myofibroblast-like cells and collagen; it does not metastasize but can cause significant local morbidity. Most sporadic cases are associated with mutations in the CTNNB1 gene, which encodes beta-catenin. Various treatments have been used with differing efficacy and toxicity profiles.
