Abstract
ABSTRACT
        Background and Objective: Mycotoxins are a group of relatively resistant toxic metabolites. The most important mycotoxins are aflatoxins (B1 and B2, G1 and G2), which originate from contaminated animal feed. Dairy cattle transmit aflatoxins B1 and B2 through milk in form of aflatoxins M1 and M2, and endanger the human health. Traditional buffalo farms play an important role in the supply of dairy products in Khuzestan Province. In addition, the province has suitable conditions for the growth of various types of fungi. Therefore, this study aimed to determine the amount of aflatoxins in buffalo feed samples collected from two main suppliers of milk in the province (Ahvaz and Karun).
         Methods: Overall, 60 samples were collected during the 3 months of autumn 2014. Samples were analyzed by the sensitive and fast method of competitive enzyme-linked immunosorbent assay.
         Results: The concentration of aflatoxin ranged from 0.77 to 64.85 μg/Kg. In addition, the concentration of aflatoxin in 21 samples was higher than the permitted limit (25 μg/Kg).
        Conclusion: The mean concentration of aflatoxin in the samples increases with the decrease in temperature and humidity. This increase is observed in Ahvaz at a higher rate, which could be due to inappropriate storage and use of rice bran in their feed.

Abstract
Background: Blood products are vital yet scarce medical resources. In teaching hospitals, inefficient transfusion practices often result in unnecessary waste, compromising both patient safety and healthcare costs. This study investigated the patterns and underlying causes of unused blood products at Imam Reza Hospital, a major tertiary center in northeast Iran, with the aim of delineating modifiable factors contributing to this issue.

Methods: This retrospective cross-sectional study was conducted at Imam Reza Hospital, Mashhad. Data were extracted from the Laboratory Information System (LIS) and the hospital’s dashboard for the period of March 2022–2025. Blood component reserve and return data for five large clinical departments were examined.

Results: Although the total number of returned units declined over time, the return percentage increased in the final year, indicating persisting inefficiencies. By department, Neurology and Gynecology exhibited the highest return percentages, while the Hematology-Oncology ward, Intensive Care Unit (ICU), and Emergency Department reported the highest absolute numbers of returns. Platelets were the most frequently returned product, whereas fresh frozen plasma had the highest relative return rate. The most consistently reported reason for returns was “Physician Decision / Order Canceled,” with returns due to “Patient Death” also showing a gradual increase over the study period.
Conclusion: Despite gradual improvements, systemic challenges—especially poor documentation, absence of digital monitoring tools, and knowledge gaps in transfusion handling—continue to undermine efficient blood product use. Implementing real-time dashboards, enforcing mandatory documentation, educating clinical staff, and adopting AI-based demand prediction tools could dramatically reduce waste and enhance transfusion practices.
