This study analyzed the effects of psychological responses (impulsivity, self-esteem, self-confidence, and anxiety) in baseline and pre-competitive contexts of national soccer referees (SRs), their control of the game (yellow and red cards), and physical performance (PP) according to the role (assistant or main referee), and experience in the category. Twenty-seven national SRs from Spain participated in this study. Baseline and pre-competitive psychological data were collected through the Competitive State Anxiety Inventory-2 (CSAI-2 test), Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, Positive Urgency, Impulsive Behavior Scale (UPPS-P test), and Rosenberg tests. Furthermore, WIMU PRO™ inertial devices were used to monitor PP. The results indicated that a lack of perseverance and self-esteem were higher in the main SRs and somatic anxiety in assistant SRs. Experience of SRs was related to anxiety, self-confidence, self-esteem, impulsivity dimensions, and PP metrics (p < 0.05). Finally, red cards were related to positive and negative urgency (r = 0.38 and r = 0.35, p < 0.05, respectively). In conclusion, the main SRs and SRs with more experience had better psychological characteristics and PP in a competitive context. However, yellow and red cards were not associated with these factors, although red cards were related with urgency. Based on these data, specific training programs could be incorporated to enhance emotional control in SRs with less experience to achieve greater performance and professional development.

This study aimed to examine the differences in physical performance when winning and losing in UEFA Champions League (UCL) matches. Data were collected using an optical tracking system from all UCL matches (n = 125) in the 2022/23 season. A linear mixed model was used to examine the differences in physical performance in won and lost matches while controlling for match location, team formation, opponent quality, playing time, red cards, and between-player, -team, and -match variations.

Objective: To establish a method for preserving viral nucleic acids in plasma using a blood collection card based on the dry spot method, to predict the duration of nucleic acid preservation by establishing the Arrhenius equation, and to demonstrate the feasibility of this preservation method for the re-testing of nucleic acids in blood samples retained by blood banks.
Methods: Plasma samples positive for HBV, HCV, and HIV nucleic acids were prepared into preservation cards in the form of dry plasma spots for storage. The prepared preservation cards were placed under accelerated storage conditions at 37, 45, 50, and 55 ℃.

Objective: To investigate and assess hemolytic transfusion reaction in patient with complex and combined anti-Fy and anti-Jk which so as to provide a safety blood transfusion strategy.
Methods: ABO/Rh blood grouping, antibody screening and identification, and Coombs' tests were performed by the routine serological methods include manual tube and automatic blood group analyzer with matching micro-column gel cards from Diagnostic Grifols and Jiangsu LIBO. The hospital information system and laboratory information system were used to collect dada on patients' blood routine tests, liver and kidney function, coagulation, cardiac function, and other clinical indicators before and after blood transfusion were analyzed and compared in conjunction with the patients' clinical manifestations.

Background: At the regional transfusion service in the Region of Southern Denmark, serological investigations are primarily carried out using column agglutination techniques. This case study examines an unusual instance of reagent interference in pretransfusion testing using column agglutination at the Hospital of Southern Denmark, Aabenraa.
Case Presentation: A 72-year-old male patient presented for pretransfusion testing prior to hernia surgery.
