Objective: To assess the effect of glucocorticoids (GC) on damage progression in placebo-biologic arms of rheumatoid arthritis (RA) biologics trials.

Methods: Posthoc metaanalysis of 2 infliximab (IFX) trials (established and early RA) and 1 tocilizumab (TCZ) trial (established RA).

Results: The proportion of patients receiving GC was 38%-64%, baseline damage was 11-82 Sharp/van der Heijde points, and progression in the placebo groups was 0.5-4.8 points in 6 months. In the pooled IFX studies, GC cotreatment reduced 6-month progression by 2.6 points (95% CI 0.6-4.5). In the TCZ study (progression rate 0.5 Genant points), no such difference was seen.

Conclusion: GC cotreatment may affect results in RA trials.

Objective: The RATIONALE-305 trial demonstrated that tislelizumab in combination with chemotherapy regimens was more beneficial than chemotherapy regimens alone in the treatment of patients with advanced gastric cancer or gastroesophageal junction adenocarcinoma (GC/GEJC). This study aimed to evaluate the cost-effectiveness of tislelizumab combination chemotherapy in the treatment of advanced GC/GEJC from the perspective of the Chinese health service system.

Methods: A three-state partition survival model was constructed to evaluate the economics of tislelizumab combined with chemotherapy as the first-line treatment of advanced GC/GEJC.

Single chain fragment variable, a new theranostic approach for cardiovascular diseases.

Cardiovascular diseases (CVDs) remain a significant global health challenge, leading to substantial morbidity and mortality. Despite recent advancements in CVD management, pharmaceutical treatments often suffer from poor pharmacokinetics and high toxicity. With the rapid progress of modern molecular biology and immunology, however, single-chain fragment variable (scFv) molecule engineering has emerged as a promising theranostic tool to offer specificity and versatility in targeting CVD-related antigens.
