Background And Aims: Although wearing a white coat is an accepted part of medical and dental practice, it is a potential source of cross-infection. The objective of this study was to determine the level and type of microbial contamination present on the white coats of dental interns, graduate students and faculty in a dental clinic.
Materials And Methods: Questionnaire and cross-sectional survey of the bacterial contamination of white coats in two predetermined areas (chest and pocket) on the white coats were done in a rural dental care center. Paired sample t-test and chi-square test were used for Statistical analysis.
Results: 60.8% of the participants reported washing their white coats once a week. Grading by the examiner revealed 15.7% dirty white coats. Also, 82.5% of the interns showed bacterial contamination of their white coats compared to 74.7% graduate students and 75% faculty members irrespective of the area examined. However, chest area was consistently a more bacterio-logically contaminated site as compared to the pocket area. Antibiotic sensitivity testing revealed resistant varieties of micro-organisms against Amoxicillin (60%), Erythromycin (42.5%) and Cotrimoxazole (35.2%).
Conclusion: The white coats seem to be a potential source of cross-infection in the dental setting. The bacterial contamina-tion carried by white coats, as demonstrated in this study, supports the ban on white coats from non-clinical areas.

White coats, traditionally symbols of physicians' hygiene and professionalism, are now scrutinized for potential infection risks during patient interactions. This review investigates whether wearing white coats is linked to microbial contamination, infection transmission, and patient expectations. An umbrella review of peer-reviewed studies and guidelines was conducted, with searches in PubMed/Medline and Scopus using terms related to medical attire, infection control, patient perceptions, and discrimination.

Article Synopsis
- Granulocyte concentrates (GCs) can be made from pooled buffy coats of whole blood donations, allowing for better availability and longer storage times compared to those made from single-donor apheresis, which can only last 24 hours.
- A process was developed to significantly reduce red blood cell and platelet contamination, extending the shelf life of GCs up to 72 hours while maintaining high cell viability (above 98%) and functionality (with over 95% rates of phagocytosis and oxidative burst).
- To produce a therapeutic dose of GCs, around 15-20 buffy coats are needed, offering a more efficient alternative for treatment compared to traditional methods.
Public Perceptions of Surgeon Attire in Saudi Arabia.
Patient Prefer Adherence

Division of Vascular Surgery, Department of Surgery, College of Medicine, King Saud University, Riyadh, Saudi Arabia.
Introduction: Surgeon attire significantly affects patients' perceptions and can improve patient-surgeon relationships, which are crucial for patient comfort, experience, satisfaction, and treatment adherence. Understanding patient preferences for surgeon attire is essential, particularly in Saudi Arabia, for establishing appropriate dress codes in healthcare institutions. This national cross-sectional study aimed to fill this gap by assessing patient preferences for surgeon attire and its impact on patients' confidence in their surgeons across various medical settings.

Platelets play a crucial role in blood transfusions, and understanding the changes that occur during their storage is important for maintaining the quality of preparations. In this study, we examined key alternating factors, with a particular focus on platelet activation and the release of extracellular vesicles. Additionally, we compared two detection methods-imaging flow cytometry (IFC) and nanoparticle tracking analysis (NTA)-for their effectiveness in detecting particles.

The Bambara groundnut is the indigenous legume in the southern part of Thailand. It contains a seed coat rich in polyphenols, which can serve as natural antimicrobial agents. The extracts from red and white seed coats of Bambara groundnuts, namely RSC and WSC, respectively, were prepared using an ultrasound-assisted extraction process.
