The role of antibiotics in preventing surgical complications in periodontology and implant dentistry

Periodontology 2000, EarlyView.
Abstract Antibiotics are commonly prescribed in periodontal and implant surgeries, either before, during or after surgery, to prevent postoperative infection and reduce early implant failure. However, the potential benefits may be undermined by the risks of resistance and sensitization, thus requiring a strict indication for prescription.

Donor retention and return patterns in Saudi Arabia: Implications for blood safety and supply stability

Transfusion Medicine, EarlyView.
Abstract Background Sustaining a safe and sufficient blood supply requires not only recruiting first‐time donors but also retaining them over time. In Saudi Arabia, donor retention remains poorly understood, with limited data on return behavior, demographic influences, and temporal trends.
