Effect of platelet count on long-term prognosis of cerebral infarction

OBJECTIVE

This study aimed to analyze the correlation between platelet (PLT) count and the modified Rankin scale (mRS) in patients with cerebral infarction (CI) at the later stage of rehabilitation, which can be used to guide the secondary prevention strategy of CI.

METHODS

A total of 180 CI patients were divided into three groups according to PLT count: low PLT group (<125×109/L), medium PLT group (126- 225×109/L) and high PLT group (>226×109/L). The mRS was evaluated after three months and one year, respectively, and the difference in long-term prognosis between groups was analyzed. The mRS is an ordered scale coded from 0 (no symptoms at all) through 5 (severe disability) 6 (death).

RESULTS

Finally, a total of 99 patients had complete data. The results of the multiple comparisons among the three groups were as follows: the analysis of variance of the mRS at three months after onset yielded F = 6.714 and P = 0.002, and the difference was statistically significant. The mRS was lowest in the medium PLT group (2.09±1.465), and neurological function recovery was the best. After one year, the mRS for the medium PLT group was the lowest (1.49±1.523), with F = 6.860 and P = 0.002. The repeated measures analysis of variance revealed that the effect of continuous rehabilitation was significant in the interval from three months to one year after onset (F = 35.528, P < 0.001). This was very significant, especially for patients taking aspirin (F = 50.908, P < 0.001). However, for patients who did not take aspirin, the effect of continuous rehabilitation was not obvious during the nine months, and the difference between the results of two mRS measurements was not statistically significant (F = 1.089, P = 0.308).

CONCLUSIONS

Patients with a PLT count of 126- 225×109/L had the lowest mRS between three months and one year after onset, but had the best recovery of nerve function. Patients who persisted in taking aspirin continued to significantly recover during the 9-month period, from three months to one year after onset. Aspirin is not only a secondary preventive drug, but also an important drug to promote the rehabilitation of CI patients.

Effects of SuperUlam on Supporting Concentration and Mood: A Randomized, Double-Blind, Placebo-Controlled Crossover Study

Background. SuperUlam is a proprietary blend of natural ingredients aimed at supporting brain health. We aimed to evaluate the effect of SuperUlam on attention and mood in healthy adults. Methods. Twenty healthy individuals aged 35–65 were enrolled in this randomized, double-blind, placebo-controlled, crossover study. Study duration was 3 weeks and consisted of 3 visits. Measurement of cognitive function included computer-based testing of reaction time, complex attention, working memory, sustained attention, and executive functioning. Mood testing was performed via the profile of mood states (POMS) survey and the Chalder fatigue scale. Results. Cognitive function testing demonstrated a significant improvement from baseline in executive functioning, cognitive flexibility, reaction time, and working memory in the product group only (P < 0.05). When comparing the study product to placebo, the data demonstrated a significant decrease in tension, depression, and anger (P < 0.05). There was no significant difference between the product and placebo in the other measures of mood, including vigor, fatigue, confusion, and total mood disturbance. No adverse events were reported. Conclusions. Supplementation with SuperUlam is safe to consume with potential benefits to cognitive function and mood.
