Performance of Large Language Models in Answering Juvenile Systemic Lupus Erythematosus Questions: A Blinded Expert-based Comparative Study

Background: Large language models are increasingly used to obtain medical information, but their performance in juvenile systemic lupus erythematosus remains insufficiently characterized. Objective: To compare expert-rated response quality and clinical relevance across 4 artifici...

Bracing in adult scoliosis: a scoping review of clinical outcomes

Bracing is commonly used as a conservative treatment for scoliosis, but its effects in adults with scoliosis remain unclear. To map and synthesize the existing evidence on the effects of bracing in adults with scoliosis, focusing on radiological outcomes, pain, physical function,...

Metabolic pathways are associated with increased estimated cardiovascular risk in major depressive disorder: a QRISK3-based analysis

Background Depression and anxiety are among the most commonly encountered disorders in psychiatric practice. Previous studies have shown that both cardiovascular disease and cardiovascular risk are increased in these disorders. This study aimed to investigate the potential relati...

Association between intraprocedural oxygen administration and postprocedural pneumothorax after ct-guided transthoracic lung biopsy

Abstract Background Pneumothorax is the most common complication of computed tomography (CT)-guided transthoracic lung biopsy (TLB). Whether supplemental oxygen administered during the procedure before pneumothorax detection is associated with postprocedural pneumothorax remains...

Barriers to research engagement among medical students in Türkiye: the role of environmental factors
