Abstract
The storage of platelets in additive solution (PAS) had lagged behind red cell concentrates, especially in North America. The partial or complete removal of anticoagulated plasma and storage of platelet concentrates in AS presents many advantages. The PAS can be formulated to optimize aerobic metabolism or decrease platelet activation, thus abrogating the platelet storage lesion and potentially improving in vivo viability. Plasma removal has been shown to reduce allergic reactions and the plasma harvested could contribute to the available plasma pool for transfusion or fractionation. PAS coupled to pathogen reduction technology results in a platelet product of equivalent hemostatic efficacy to conventionally stored platelets. Given the above, the likely future direction of platelet storage will be in new generation designer PAS with an extended shelf life and a superior safety profile to plasma stored platelets. J. Clin.

Abstract
BACKGROUND In the SToP platelet dose study, the World Health Organization (WHO) bleeding grade was assigned using adjudication. This study describes the challenges associated with adjudicating bleeding events and compares the adjudicated and bedside results for bleeding grade. STUDY DESIGN AND METHODS To categorize bleeding, the following information was provided to adjudicators: daily bleeding assessments, interventions to stop or control bleeding, daily blood counts, and transfused blood components. Each daily assessment was sent to two adjudicators who independently assigned a grade and anatomic site of bleeding. Discordant cases where disagreement occurred were sent to a third adjudicator and subsequently to a fourth or fifth adjudicator in an attempt to reach agreement. Disagreement after five adjudicators was resolved by consensus. The final adjudicated grade was compared with the grade of bleeding assigned at the bedside by study personnel. RESULTS A total of 1150 case report forms were adjudicated. Disagreement on grade of bleeding was common: 31.2% after the first two adjudicators, 4.0% after the third adjudicator, 0.7% after four, and 0.05% after five. Disagreement on anatomic site was less but still occurred in 17% of cases after two adjudicators. The frequency of bleeding (≥ Grade 2) based on adjudication was higher than bedside grading (standard-dose arm, 47.5% vs. 34.4%; low-dose arm, 50.0% vs. 43.1%). CONCLUSION The frequency of WHO bleeding varies depending on the method used to assign grade. Adjudication to assign bleeding grade resulted in significant disagreement when two adjudicators were used.

Abstract
BACKGROUND Observational studies have reported that patients transfused with red blood cells (RBCs) have a worse clinical outcome than untransfused patients and that storage age of RBCs at the time of transfusion may be an independent predictor of this adverse clinical outcome. STUDY DESIGN AND METHODS Eight RBC concentrates in additive solution were studied over an 8-week storage period. The RBC supernatant was ultracentrifuged to concentrate microvesicles (RCMVs). RCMVs were studied by flow cytometry to identify phosphatidylserine (PS)-expressing RCMVs and in a thromboelastograph (TEG) using a modified assay to detect a thrombin facilitation effect. RESULTS For all products, the percentage of RCMVs that exhibited PS expression on Day 1 was 50 ± 13%, which increased with storage, and on Day 31 was 90 ± 4%. After 31 days, four of the eight products showed a thrombin facilitation effect as evidenced by a shortening of the TEG reaction (R) time of 1.3 ± 1.1 minutes, which persisted to Day 41. Data are the mean ± 1 SD. This TEG R shortening effect was neutralized by annexin V. No such effect was observed on, or before, Day 21. CONCLUSIONS Some stored RBCs release RCMVs, which express PS and are capable of facilitating thrombin generation in vitro. This provides a possible mechanism by which stored RBCs could promote adverse thrombotic or inflammatory effects.

Abstract
It is recognized that young people experience difficulties in accessing mainstream mental health services particularly because of the stigma that remains associated with mental health problems. One potential solution is to use the many websites available offering information and support for mental health problems, such support and information could be offered by Psychiatric Nurses. However, young peoples' usage and views on using the Internet for this purpose has yet to be examined. This quantitative descriptive study aimed to elicit the views of 922 University students, aged between 18 and 24 years, on using the Internet for mental health information and support. Data were collected using a 30-item self-designed questionnaire and analysed using descriptive statistics. The findings indicated that 72.4% of participants used the Internet several times a day. In addition, 30.8% had previously searched for mental health information online, predominantly on depression. While it was found that 68% of participants indicated that they would use the Internet for mental health support if they needed to, 79.4% would still prefer face to face support. It is concluded that young people are willing to use the Internet for mental health information and that it represents a viable source of support for this age group.
