Comparative Study Controlled Clinical Trial
Resistance to low-dose aspirin therapy among patients with acute coronary syndrome in relation to associated risk factors.
A substantial proportion of patients have recurrence of vascular events despite daily intake of low-dose aspirin therapy. Therefore, different patients may require different aspirin dosages to achieve complete inhibition of platelet function. ⋯ There is inter-individual variability in response to the antiplatelet effect of standard doses of aspirin (150, 300 mg/day). The response to aspirin 300 mg/day is enhanced in resistant patients when compared to 150 mg/day. There was a significant association between aspirin resistance and atherothrombotic risk factors (diabetes, hyperlipidaemia and obesity).

Case Reports Comparative Study
Thrombopoietin receptor agonists in refractory immune thrombocytopenia: differential responses to eltrombopag and romiplostim: a case report and possible explanations.
Although new thrombopoietin (TPO) receptor agonist drugs, such as romiplostim and eltrombopag, are highly effective and well tolerated for patients with immune thrombocytopenia (ITP) refractory to first-line treatments such as prednisolone, the cross-resistance of these two TPO receptor agonists is still unknown. ⋯ The successful treatment of ITP refractory to eltrombopag with romiplostim strongly suggests that the absence of cross-resistance between these two approved TPO receptor agonists and possible differences in mechanism of action. Further study of the mechanisms of action of TPO receptor agonists is called for along with further exploration of the potential of romiplostim in refractory ITP.

Older hospital inpatients are often prescribed complex multi-drug regimens; increased regimen complexity is associated with poorer medication adherence and treatment outcomes. There has been little research into methods for reducing regimen complexity. The objective of this study was to explore the feasibility of incorporating medication regimen simplification into routine clinical pharmacist care for older hospital inpatients and identify barriers to regimen simplification at a major teaching hospital. ⋯ This is the first study to explore pharmacist-led medication regimen simplification and barriers to regimen simplification in the hospital setting. It demonstrates that simplification of older inpatients' regimens is feasible when training in regimen simplification is provided. The main barrier to regimen simplification appears to be lack of pharmacist time.
