Is increased sympathetic activation in patients with vasovagal syncope associated with higher mean platelet volume levels?
We found that MPV was closely associated with increased sympathetic activity in patients with VVS. Our analysis supports the hypothesis that alterations in autonomic status might play a role in the development of platelet size.
The numerous demographic, clinical, and psychopathological overlapping characteristics in unipolar and bipolar mania raise questions about the general nosographic utility of this categorization. Nonetheless, our data suggest a clinical and prognostic validity of keeping unipolar manic patients as a separate subgroup, in particular, as social adjustment and disability are concerned.
