Abstract
Studies on nondialysis populations have linked visit-to-visit blood pressure (BP) variability (BPV) to cerebrovascular events and mortality. In view of the high prevalence of hypertension in hemodialysis patients, the predictive values of numerous factors for stroke, especially visit-to-visit BPV, were evaluated in this prospective cohort study.A total of 151 patients were enrolled in this study. The demographic features and various laboratory parameters were analyzed. At each routine hemodialysis visit, the predialysis, intradialysis, and post-dialysis BP measurements were systematically performed. We defined BPV using 4 metrics: standard deviation of the BP, coefficient of variation, average real variability (ARV), and variability independent of mean (VIM). Differences in the predialysis BPs from one treatment to the next (ie, interdialytic variability) and differences in the BPs from predialysis to post-dialysis (ie, intradialytic variability) were both studied in this work.Twenty-one patients developed stroke and 25 patients died. The multivariate Cox proportional hazards regression model revealed a significant relationship between stroke and the interdialytic BPV (both predialysis systolic BP variability and predialysis diastolic BP variability) and low-density lipoprotein-cholesterol (LDL-C).Our results indicate that a high interdialytic BPV is associated with an increased risk for stroke that is independent of several factors, including age, sex, antihypertensive medication use, and mean BP over time. There is potential that the optimal treatment goal for hemodialysis patients may be to reduce the interdialytic BPV rather than either the mean BP or the intradialytic BPV.

Abstract
Aim: Monocyte-to-high-density lipoprotein ratio (MHR) recently emerged as an inflammatory marker and has been reported to be a novel prognostic indicator of cardiovascular diseases. However, the relationship between MHR and prognosis of acute ischemic stroke (AIS) remains unclear. Methods: Consecutive AIS patients were prospectively identified from January 2015 to December 2017. Functional outcome was evaluated by the modified Rankin Scale (mRS). Poor outcome was defined as of mRS 3–6. Multivariate logistic regression analysis was conducted to evaluate the relationship between MHR and poor outcome. Results: A total of 1090 AIS patients within 24 hours of the onset of symptoms were recruited. MHR was higher in poor outcome group compared to that in good outcome group [0.53 (0.37–0.69) vs. 0.48 (0.33–0.60), P = 0.007]. Multivariate logistic regression analysis indicated that higher MHR level was independently associated with the poor outcome at 3 months (OR 2.58, 95% CI, 1.21–5.51, P = 0.015), especially the stroke subtype of large artery atherosclerosis (OR 2.52, 95% CI, 1.03–6.19, P = 0.034). Receiver operating curve (ROC) analysis showed that the area under the ROC curves for MHR was 0.67 and the best predictive cutoff value of MHR was 0.51, with a sensitivity of 62.3% and a specificity of 66.5%. Conclusions: MHR may be a significant and independent predictor of poor functional outcome in patients with AIS.

Abstract
Objectives: This study aimed to assess the preoperative risk factor for perioperative ischemic stroke (PIS) in patients undergoing non-cardiovascular and non-neurological surgeries.Methods: Patients were retrospectively enrolled and grouped into two groups at a ratio of 1:2 according to their PIS status, i.e. patients with PIS in disease group, and patients without PIS in control group. Univariate analysis and multivariate logistic regression analysis were performed on admission laboratory test indices and preoperative risk factors for stroke. The pooled cohort equation (PCE), Essen Stroke Risk Score (ESRS), and Stroke Prognostic Instrument II (SPI-II) were used to separately assess the risk of stroke in patients with or without a history of stroke.Results: There were significant differences between the two groups in the levels of high-density lipoprotein cholesterol (HDL-C), prealbumin, renal insufficiency, dyslipidemia, coronary heart disease, anemia, and hemoglobin; the incidence of electrolyte disturbance; and previous histories of smoking, drinking, and stroke. Multivariate logistic regression analysis showed that renal insufficiency, histories of smoking and stroke, and decreased HDL-C can increase the risk of PIS. There were no significant differences between the disease group and the control group in ESRS or SPI-II score in patients with stroke history. There was a significant difference between the two groups in the risk of PIS evaluated by PCE in patients without stroke history.Conclusions: History of stroke and smoking, renal insufficiency, and low HDL-C are independent risk factors for PIS. It is feasible to assess the risk of stroke in preoperative patients using PCE in clinical practice.

Abstract
BACKGROUND The impact of low-density lipoprotein cholesterol (LDL-C) levels on outcomes in patients with non-diabetic acute ischemic stroke remains uncertain. The objective of this study was to explore whether LDL-C could refine outcomes after acute ischemic stroke in patients with non-diabetic acute ischemic stroke. MATERIAL AND METHODS A multi-center, retrospective, clinical-based study was conducted within eight hospitals between January 2015 and August 2016. Adjusted odds ratio (aOR) was used for measurement of unfavorable outcome which was evaluated by the modified Rankin Scale (mRS) score at 6 months after acute ischemic stroke, estimated categorically according to multivariate logistic regression. RESULTS A total of 1614 participants with non-diabetic acute ischemic stroke were enrolled, of which 376 patients (23.3%) had unfavorable neurologic outcomes at 6 months. After multivariate analysis comparing 4 LDL-C levels by quartiles (Q), we found that compared to Q1 (LDL-C level ≤2.41 mmol/L), there was a significant association between the frequency of unfavorable outcomes and levels of LDL-C (Q3: 2.95-3.54 mmol/L) for all participants (adjusted odds ratio [aOR]=0.63; 95% CI: 0.44-0.92, P=0.016) and patients with first ever strokes (aOR=0.52; 95% CI: 0.31-0.87, P=0.013). CONCLUSIONS Compared to lower LDL-C levels, non-diabetic patients with LDL-C levels in Q3 (2.95-3.54 mmol/L), were less likely to have unfavorable functional outcomes at 6 months after acute ischemic stroke. Managing HDL-C is one of the most important steps for the recovery of acute ischemic stroke.

Serum 2-methoxyestradiol, an estrogen metabolite, is positively associated with serum HDL-C in a population-based sample. Lipids 2011; 47:35-8.

Abstract
Serum HDL cholesterol (HDL-C) is inversely associated with coronary artery disease, ischemic stroke, and atherosclerosis in men and women. Among postmenopausal women, oral conjugated equine estrogen (CEE) increases serum HDL-C. This is due to activation of hepatic nuclear estrogen receptors, resulting in increased HDL-C expression, as well as modulation of proteins which metabolize HDL-C. 2-methoxyestradiol (2-MeOE2), an estrogen metabolite, has several vasculoprotective effects and may play a role in HDL-C production. 2-MeOE2 inhibits HMG-CoA reductase in vitro but no study has examined the relationship between serum 2-MeOE2 and serum HDL-C. A population-based sample provided information regarding demographic characteristics and use of antihyperlipidemic medications. Serum was analyzed for 17β-estradiol (E2), estrogen metabolites (EMs), and lipoproteins. Results included serum EM data from 51 men and 47 postmenopausal women. Preliminary analysis revealed no correlation between 2-MeOE2 and serum HDL-C in men so the current analysis includes only women (N = 40) with no missing demographic, medication, EM, or lipoprotein data. Linear regression revealed that serum 2-MeOE2 and antihyperlipidemic medications were positively associated with serum HDL-C (β = 0.276, P = 0.043, and β = 0.307, P = 0.047, respectively) when age, race/ethnicity, and body mass index were held constant. Prospective studies are needed to determine if 2-MeOE2 is causally related to HDL-C in women.

Abstract
OBJECTIVE To examine the association of childhood headache disorders with markers of risk for cardiovascular and cerebrovascular disease. DESIGN Information was collected on severe or recurrent headache or migraine in childhood or adolescence and on biomarkers predictive of vascular disease. SETTING The National Health and Nutrition Survey, a nationally representative health survey. PARTICIPANTS Children or adolescents aged 4 to 19 years (n = 11 770) who took part in the National Health and Nutrition Survey in 1999 through 2004. MAIN EXPOSURE Headache. MAIN OUTCOME MEASURES Body mass index; levels of C-reactive protein, homocysteine, serum and red blood cell folate, vitamin B(12), methylmalonic acid, total cholesterol, high-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, triglycerides, and uric acid; and platelet count. RESULTS Mean values for body mass index, C-reactive protein, and homocysteine were higher in children with than without headaches, and more children with headaches were in the highest quintile of risk for these factors. Serum and red blood cell folate levels were lower in children with headache. More children with headache were in the highest quintile of risk for 3 or more of these factors. CONCLUSIONS Several important risk factors for long-term vascular morbidity cluster in children and adolescents with severe or recurrent headache or migraine. Further study and screening of children with headaches may permit improved preventive management.
