The activities of the oxygen radical scavenging enzymes [glutathione-peroxidase (GSH-POD), superoxide dismutase (SOD), and guaiacol peroxidase (G-POD)], hydrogen peroxide scavenging enzymes in the ascorbate-glutathione cycle [ascorbate peroxidase (AsA-POD), monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), and glutathione reductase (GR)], the nonenzyme components [ascorbate (AsA), dehydroascorbate (DHAsA), glutathione (GSH), and oxidized glutathione (GSSG)], and their antioxidant capacity [oxygen radical absorbance capacity (ORAC)] were measured in the juice of six different thornless blackberry (Rubus sp.) cultivars. The 'Hull Thornless' cultivar contained the highest levels, whereas 'Black Satin' consistently had the lowest activities for all the enzymes tested in this study. ORAC values were also the highest in 'Hull Thornless' and lowest in 'Black Satin'. The highest levels of AsA and DHAsA were in the juice of 'Hull Thornless' blackberries with 1. 09 and 0.15 micromol/g fresh wt, respectively. 'Hull Thornless' also had the highest ratio of AsA/DHAsA among the six blackberry cultivars studied. The 'Smoothstem' cultivar contained the lowest amounts of AsA and DHAsA. 'Hull Thornless' had the highest GSH content with 78.7 nmol/g fresh wt, while 'Chester Thornless' contained the largest amount of GSSG. The highest GSH/GSSG ratio was 4.90 which was seen in the 'Hull Thornless' cultivar. The correlation coefficient between ORAC values and AsA/DHAsA ratios was as high as 0.972. A correlation (r = 0.901) was also detected between ORAC values and GSH content. The antioxidant activity in blackberry juice was positively correlated to the activities of most antioxidant enzymes (r = 0.902 with SOD; r = 0.858 with GSH-POD; r = 0.896 with ASA-POD; and r = 0.862 with GR).

Progesterone produces a small but significant decrease in miscarriage among pregnant women with 3 or more unexplained pregnancy losses (strength of recommendation [SOR]: A, based on a meta-analysis of 3 small randomized controlled trials [RCTs] with wide confidence intervals). Human chorionic gonadotropin (HCG) reduces the rate of recurrent pregnancy loss among women with 2 or more unexplained pregnancy losses (SOR: B, based on a meta-analysis of 4 RCTs with significant methodologic weaknesses). Four types of immunotherapy are ineffective for preventing miscarriage (SOR: A, based on RCTs and systematic reviews of RCTs). Aspirin therapy is ineffective for preventing recurrent miscarriage for women who do not have an autoimmune explanation for previous pregnancy losses (SOR: A, based on RCTs).

Alternative antiplatelet therapy for stroke prevention is indicated for patients who experience transient ischemic attacks (TIAs) while on aspirin therapy (strength of recommendation [SOR]: A, based on 1 meta-analysis and 1 randomized controlled trial). The combination of aspirin and extended-release dipyridamole reduces the risk of stroke following a TIA (SOR: A). Thieno-pyridines (eg, clopidogrel and ticlopidine) are an alternative for patients at high risk for a cardioembolic event. Ticlopidine reduces the risk of stroke following TIA, specifically showing benefit for patients previously on aspirin (SOR: A). Clopidogrel has not shown significant reduction in reoccurrence of stroke and has not been studied for patients with a previous TIA. Aspirin and a thieno-pyridine do not provide significant additional reduction in secondary strokes (SOR: A).

Aspirin should not be used to treat acute febrile viral illness in children. (Strength of Recommendation [SOR]: C, based on case-control studies). Although no causal link has been proven, data from case-control and historic cohort studies demonstrate an association between aspirin use and Reye syndrome. The risk of Reye syndrome decreases with age, becoming extremely rare by the late teenage years. Other nonsteroidal anti-inflammatory drugs are effective antipyretics and are not associated with the constellation of symptoms seen in Reye syndrome, which includes nausea, vomiting, headache, excitability, delirium, combativeness, and coma. Aspirin use in children younger than 19 years should be limited to diseases in which aspirin has a proven benefit, such as Kawasaki disease and the juvenile arthritides. (SOR: C, based on expert opinion).
