Longitudinal association between fasting blood glucose concentrations and first stroke in hypertensive adults in China: effect of folic acid intervention.
CONCLUSIONS: In Chinese hypertensive adults, an FBG concentration ≥7.0 mmol/L or diabetes is associated with an increased risk of first stroke; this increased risk is reduced by 34% with folic acid treatment. These findings warrant additional investigation. This trial was registered at clinicaltrials.gov as NCT00794885. PMID: 28122783 [PubMed - as supplied by publisher]

Medical cost savings in Sakado City and worldwide achieved by preventing disease by folic acid fortification.
Abstract The introduction of mandatory fortification of grains with folate in 1998 in the United States resulted in 767 fewer spina bifida cases annually and a cost savings of $603 million per year. However, far more significant medical cost savings result from preventing common diseases, including myocardial infarction, stroke, dementia and osteoporosis. A cost‐effectiveness analysis showed a gain of 266,649 quality‐adjusted life‐years and $3.6 billion saved annually, mainly due to the reduction of cardiac infarction. The recommended folate intake in Japan is 240 µg//d whereas it is 400 µg//d internationally. ...

Folic acid supplementation and chronic kidney disease progression
In contrast to prior studies demonstrating no benefit or even increased harm from B vitamin supplementation in patients with chronic kidney disease, a large randomized trial from China recently demonstrated small but statistically significant reductions in the risk of first stroke and chronic kidney disease progression with the addition of folic acid to enalapril in adults with hypertension. Differences in the study population and study intervention may explain these discordant results.

Efficacy of Folic Acid Therapy on the Progression of Chronic Kidney Disease The Renal Substudy of the China Stroke Primary Prevention Trial
In this substudy of eligible China Stroke Primary Prevention Trial (CSPPT), 15 104 participants with an estimated glomerular filtration rate (eGFR) 30 mL/min/1.73 m2 or greater, were randomized to receive a single tablet daily containing 10 mg enalapril and 0.8 mg folic acid (n = 7545) or 10 mg enalapril alone (n = 7559). Overall, 15 104 Chinese adults with a mean (range) age of 60 (45-75) years were recruited; median follow-up was 4.4 years. There were 164 and 132 primary events in the enalapril group and the enalapril-folic acid group, respectively. Compared with the enalapril group, the enalap...

Folic Acid Therapy Reduces the First Stroke Risk Associated With Hypercholesterolemia Among Hypertensive Patients Clinical Sciences
Background and Purpose—We sought to determine whether folic acid supplementation can independently reduce the risk of first stroke associated with elevated total cholesterol levels in a subanalysis using data from the CSPPT (China Stroke Primary Prevention Trial), a double-blind, randomized controlled trial.Methods—A total of 20 702 hypertensive adults without a history of major cardiovascular disease were randomly assigned to a double-blind daily treatment of an enalapril 10-mg and a folic acid 0.8-mg tablet or an enalapril 10-mg tablet alone. The primary outcome was first stroke.Results—The median treatment durat...

Folic acid deficiency increases brain cell injury via autophagy enhancement after focal cerebral ischemia
Folic acid (FA) deficiency is not only associated with an increased risk of ischemic stroke, but also with increased oxidative DNA damage and brain injury after cerebral ischemia –reperfusion. However, the cellular and molecular mechanisms underlying FA deficiency-associated neuropathogenesis are not completely understood. In the present study, we tested the hypothesis that neuronal autophagy in focal cerebral ischemia rats may be involved in the mechanisms of FA deficienc y -induced injury to neuronal cells.

Folic Acid Supplementation and the Risk of Cardiovascular Diseases: A Meta-Analysis of Randomized Controlled Trials Epidemiology
Conclusions Our meta-analysis indicated a 10% lower risk of stroke and a 4% lower risk of overall CVD with folic acid supplementation. A greater benefit for CVD was observed among participants with lower plasma folate levels and without preexisting CVD and in studies with larger decreases in homocysteine levels. Folic acid supplementation had no significant effect on risk of coronary heart disease.

Effectiveness of Gotu Kola Extract 750 mg and 1000 mg Compared with Folic Acid 3 mg in Improving Vascular Cognitive Impairment after Stroke.
This study aimed to determine the effectiveness of gotu kola (Centella asiatica) in improving cognitive function in patients with vascular cognitive impairment (VCI). This study uses a quasi-experimental design. Subjects in this study were patients with poststroke cognitive impairment who were treated at two hospitals in Yogyakarta, Indonesia. The number of subjects was 48: 17 subjects were treated with 1000 mg/day of gotu kola extract, 17 subjects treated with 750 mg/day of gotu kola extract, and 14 subjects treated with 3 mg/day of folic acid for 6 weeks. A Montreal Cognitive Assessment-Indonesian version (MoCA-Ina...

Efficacy of folic acid in primary prevention of stroke among patients with hypertension in China
After folic acid had been documented to reduce birth defects, the United States mandated folic acid food fortification in grain products in 1996 and implemented the policy by 1998.1 Around this time, controversy surfaced on adverse effects of folic acid, namely its possible role in promoting carcinogenesis. However, data over the next decade failed to provide sufficient evidence to support such a claim.1,2 In addition to decreasing neural tube defects, folic acid supplementation has been hypothesized to decrease the risk of stroke and cardiovascular events; however, among the multiple randomized controlled studies thus far...
