Article Synopsis
- This study examines the role of ChatGPT in diagnosing tibial plateau fractures by comparing its performance against a board-certified emergency physician and a radiologist.
- A total of 111 knee radiographs were analyzed, revealing that while ChatGPT-4o performed comparably to the human experts, ChatGPT-4 lagged significantly behind.
- The findings suggest that while AI tools like ChatGPT can assist in diagnosis, they currently do not match the accuracy of trained medical professionals for this specific type of fracture.
Objectives: This study aimed to determine the epidemiology of eye injuries in children and the influential factors involved.
Methods: Eighty cases of confirmed ocular trauma were included in this cross-sectional study. Data were obtained via a checklist containing demographic information, site of the insult, the interval between the injury and physician visit, trauma mechanism, and medical history, including previous history of ocular trauma.
In this study, we have analyzed the evolution of serum HBsAg levels in 16 patients with chronic hepatitis B who showed an HBsAg seroconversion following antiviral therapy. The data showed that the clearance of serum HBsAg is slower than that of serum HBV DNA, which may reflect a slow kinetics of clearance of infected hepatocytes. Interestingly, HBsAg was detectable for a longer time using the Architect assay than with the Bio-Rad assay.

This retrospective cohort study evaluated the safety and efficacy of ADV in this specific patient population.
Methods: Sixty-eight cirrhotic LAM-R patients, of whom 19 (27.
Background: Hepatitis B is endemic in the Amazon region.
Methods: Serological markers for hepatitis B virus (HBV) were determined in 266 household members for hepatitis B surface antigen (HBsAg)-positive women (G1) and 395 household members for HBsAg-negative women (G2), randomly selected in Acre State Women's Medical Care Program, in order to evaluate the prevalence of HBV in this population. Before blood sample collection an epidemiological questionnaire was applied.
