Abstract

fetched live from OpenAlex

<b><i>Background:</i></b> Hypertension and hyperhomocysteinemia (HHcy) are independent risk factors of stroke and are associated with each other. Although evidence suggests that they are related to cognitive impairment, the relationship between hypertension accompanied with HHcy and poststroke cognitive impairment (PSCI) is unclear. <b><i>Objective:</i></b> To define the relationship between hypertension with HHcy and early cognitive impairment after acute cerebral infarction. <b><i>Materials and Methods:</i></b> Our study enrolled 232 patients with acute first-ever ischemic stroke. Patients were assigned to 3 groups by blood pressure and homocysteine (Hcy) levels: hypertension with HHcy, simple hypertension, or control. Cognition was assessed by the Montreal cognitive assessment at admission and at 3- and 6-month follow-ups. <b><i>Results:</i></b> The hypertension with HHcy group exhibited the highest incidence of early cognitive impairment (simple hypertension: <i>p</i> = 0.000; control: <i>p</i> = 0.000). This group also had lower visual space/executive scores than the simple hypertension group (<i>p</i> = 0.000) and lower delayed recall scores than the control group (<i>p</i> = 0.011). Multivariate analysis showed that hypertension with HHcy (OR 7.797; 95% CI 2.917–20.843; <i>p</i> = 0.000), the level of serum Hcy (OR 1.063; 95% CI 1.109–1.109; <i>p</i> = 0.005), education years (OR 0.797; 95% CI 0.722–0.880; <i>p</i> = 0.000), and Fazekas scale of leukoaraiosis (OR 1.648; 95% CI 1.239–2.191; <i>p</i> = 0.001) were independent influencing factors of early PSCI; however, simple hypertension (OR 1.183, 95% CI 0.208–6.737; <i>p</i> = 0.850) and simple HHcy (OR 1.112, 95% CI 0.181–6.810; <i>p</i> = 0.909) were not. <b><i>Conclusion:</i></b> Patients with both hypertension and HHcy are at an increased risk of early cognitive impairment after acute first-ever ischemic stroke.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
