Prognostic importance of paraoxonase, arylesterase and mean platelet volume efficiency in acute ischaemic stroke

Prediction is not a problem in stroke survivors you blithering idiots. Survivors want 100% recovery, they couldn't care less about predicting their recovery.  GET THEM THERE!

Abstract
Objective: To study the prognostic importance activity of paraoxonase and arylesterase, and the value of mean platelet volume in patients with acute ischaemic stroke.
Methods: This case-control study was conducted at Harran University Hospital, Sanliurfa, Turkey, from January to June 2014, and comprised patients with symptoms of acute ischaemic stroke who presented to the emergency department. Paraoxonase activity, expressed in units per litre, or U/L, of serum, was evaluated in the absence of basal activity, and arylesterase activity was defined as micromoles, of phenol generated/min, and was expressed as U/L of serum. Mean platelet volume was measured as a routine parameter. SPSS 20 was used for data analysis.
Results: Of the 94 participants, 48(51%) were patients with acute ischaemic stroke and 46(49%) were control subjects. Moreover, 27(56.3%) patients were females and 21(43.7%) were males. In the control group, 26(56.5%) were females and 20(43.5%) were males. The mean age of patients was 68.39±11.83 years compared to controls' 65±9.95 years. Decreased activity of prognostic importance and arylesterase were significant in patients than in the controls (p= 0.016 and p= 0.001, respectively). The median platelets of patients was significantly lower than that of the controls (p=0.004). However, the median mean platelet volume values were similar in the both groups (p=0.568). Binary logistic regression analyses showed that the paraoxonase and arylesterase were risk markers for the patients.
Conclusion: Decreased paraoxonase and arylesterase activity and decreased platelet counts were observed probably due to increased oxidative stress in acute ischaemic stroke patients.
