Background: Rapid, reproducible, and noninvasive diagnostic methods like Ultrasonography (US) and plethysmographic measurements such as the perfusion index (PI) and pleth variablity index (PVI) have great potential value for emergency trauma cases in which blood loss needs to be recognized quickly and accurately.
Objectives: We planned this study to evaluate the utility of US, PI, and PVI in detecting early-stage hemorrhage and mimicking volume replacement using a platelet apheresis model.
Methods: This prospective, observational study included 46 healthy platelet apheresis volunteers who met inclusion criteria.

Objective: To determine the feasibility, efficacy, and safety of cold stored compared to room temperature platelet transfusion in patients with traumatic brain injury.
Summary Background Data: Data demonstrating the safety and efficacy of cold stored platelet transfusion are lacking following traumatic brain injury.
Methods: A phase 2, randomized, open label, clinical trial was performed at a single U.

Introduction: Platelet collection by apheresis is common nowadays. Many cell separators are available in the market for the same. This study was conducted to study the effect of various donor factors on platelet yield and the effect of different cell separator variables on platelet yield.

Background: Chronic graft-vs-host disease (cGvHD) is a severe immune-mediated complication that affects patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Oral manifestations of cGvHD, such as ulcers and mucosal inflammation, significantly impair quality of life and often require long-term treatment. Existing therapies provide limited relief, prompting the exploration of new approaches, including the use of autologous platelet lysate (PL) gel for its regenerative properties.

Transfusion of platelet concentrates (PC) can be a life-saving measure in case of severe thrombocytopenia or thrombocytopathy, particularly in bleeding patients. Although acaryote, platelets are involved in several important functions including immunomodulation, but their most important function is in primary and secondary haemostasis. In this German review, apheresis and whole blood derived PC are compared and indications as well as transfusion triggers and dosage of PC are discussed.
