Abstract
OBJECTIVES Some studies show that high circulating cystatin C (CysC) may predict cardiovascular events and death after ischemic stroke onset. However, the association between serum CysC and outcome in ischemic stroke patients remains contradictory. We sought to assess the association between a specific stroke subgroup, brainstem infarction (BSI) and serum CysC. MATERIALS AND METHODS A total of 324 acute BSI patients were included in the study. Serum CysC was used to calculate estimated glomerular filtration rate (eGFRCysC) at baseline. Modified Rankin scale score ((mRS) ≥3) six months after acute BSI indicates poor functional outcome. Patients were categorized into two groups according to mRS and eGFRCysC. Logistic regression analyses were performed to determine independent risk factors. RESULTS Lower eGFRCysC was associated with hemoglobin A1c (HbA1c). This risk remained statistically significant after controlling for age, hypertension, initial National Institutes of Health Stroke Scale (NIHSS) score, HbA1c, fibrinogen and homocysteine. The serum eGFRCysC levels were significantly lower in the poor functional outcome group than the good functional outcome group (P<0.001). Multivariate logistic regression analyses showed that eGFRCysC level was significantly lower in the poor outcome group after adjusting for age, previous infarctions, initial NIHSS score, and HbA1c. CONCLUSIONS Lower eGFRCysC levels were strongly associated with poor functional outcome of acute BSI patients with a higher HbA1c level. Lower eGFRCysC may be a more helpful serologic biomarker for the prediction of prognosis in BSI.

Abstract
INTRODUCTION Endovascular thrombectomy stands as a pivotal component in the standard care for patients experiencing acute ischemic stroke with large vessel occlusion. Subsequent care for patients often extends to a neurological intensive care unit. While fluid management is integral to intensive care, the association between early fluid balance and neurological and functional outcomes post-thrombectomy has not yet been thoroughly investigated. METHODS In a retrospective analysis of an observational, single-center study spanning from 2015 to 2021 at the University Medical Center Hamburg-Eppendorf, Germany, we enrolled stroke patients who underwent thrombectomy and received subsequent treatment in the ICU. Unfavorable functional and neurological outcome was defined as a mRS > 2 on day 90 after admission (mRS d90) or NIHSS > 5 at discharge, respectively. A multivariate regression model, adjusting for confounders, utilized the average fluid balance in the first 5 days to predict outcomes. Patients were dichotomized by their average fluid balance (>1 L vs <1 L) within the first 5 days, and a multivariate mRS d90 shift analysis was conducted after adjusting for covariates. RESULTS Between 2015 and 2021, 1252 patients underwent thrombectomy, and 553 patients met the inclusion criteria (299 women [54%]). Unfavorable functional outcome was significantly associated with a higher daily average fluid balance in the first 5 days in the ICU (mRS d90 ⩽ 2: 0.3 ± 0.5 L, mRS d90 > 2: 0.7 ± 0.7 L, p = 0.02). The same association was observed for the NIHSS at discharge (NIHSS ⩽ 5: 0.3 ± 0.5 L; NIHSS > 5: 0.6 ± 0.6 L; p = 0.03). The mRS d90 shift analysis revealed significance for patients with an average fluid balance <1 L for better functional outcomes (adjusted odds ratio [AOR] 2.17; 95% confidence interval [CI] 1.54-3.07; p < 0.01). DISCUSSION Fluid retention in post-thrombectomy stroke patients in the ICU is associated with poorer functional and neurological outcomes. Consequently, fluid retention emerges as an additional potential predictor for post-intervention stroke outcomes. Our findings provide an initial indication that preventing excessive fluid retention in stroke patients after endovascular thrombectomy could be beneficial for both functional and neurological recovery. Therefore, fluid retention might be an element to consider in optimizing fluid management for stroke patients.

External Validation of the Nelson Equation for Kidney Function Decline in Patients with Acute Ischemic Stroke or Transient Ischemic Attack. Clin Interv Aging 2023; 18:901-909. [PMID: 37304172 PMCID: PMC10257475 DOI: 10.2147/cia.s407338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 06/01/2023] [Indexed: 06/13/2023] Open
Abstract
Background There is a close brain-kidney interaction following ischemic cerebrovascular disease. The new-onset kidney injury after stroke leads to severe neurological deficits and poor functional outcomes. We aimed to validate the Nelson equation for predicting the new-onset and long-term kidney function decline in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA). Methods A total of 3169 patients were enrolled in the Third China National Stroke Registry, whose baseline estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m2. The outcome of interest was the incident eGFR< 60 mL/min/1.73 m2 at 3 months. The prediction equation of participants with or without diabetes was validated respectively. The receiver operating characteristic curve (AUC) evaluated prediction performance. The Delong test compared the Nelson equation performance with the O'Seaghdha equation and the Chien equation. Continuous net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were determined to evaluate the incremental effect. Results During the 3-mo follow-up period, among 1151 patients with diabetes, there were 31 cases (2.7%) of reduced eGFR. Meanwhile, among 2018 non-diabetic patients, there were 23 cases (1.1%) of reduced eGFR. The Nelson equation showed good discrimination and was well-calibrated in patients with diabetes (AUC 0.82, Hosmer-Lemeshow test p = 0.67) or without diabetes (AUC 0.82, Hosmer-Lemeshow test p = 0.09). The performance of the Nelson equation was superior to other equation, as increased continuous NRI (diabetic, 0.64; non-diabetic, 1.13) and IDI (diabetic, 0.10; non-diabetic, 0.13) to the Chien equation. Conclusion The Nelson equation reliably predicted the risks of the new-onset and long-term kidney function decline in patients with AIS or TIA, which could help clinicians screen high-risk patients and improve clinical care.

Valtuille R. Cardiovascular Risk Related to Glomerular Hyperfiltration in Nondiabetic Individuals: Increasing Visibility is Crucial. Curr Hypertens Rev 2023; 19:139-148. [PMID: 38018215 DOI: 10.2174/0115734021268893231116045914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/30/2023] [Accepted: 11/01/2023] [Indexed: 11/30/2023]
Abstract
Glomerular hyperfiltration (GHF), defined by different estimation formulas, has been widely studied as a predictor of proteinuria and progression to chronic kidney disease (CKD) in diabetic patients. GHF is also an important cardiovascular (CV) risk factor and is related to allcause mortality in non-diabetic populations; however, the upper limit of glomerular filtration rate (GFR) above which it indicates the presence of GHF is weakly defined. This higher risk is as high as in the intermediate stages of CKD and is greater than the presence of diabetes or smoking and is still present in non-albuminuria patients. The original Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) estimation GFR formula showed lower error at higher glomerular filtration (GF) values, was the most used in population studies, and behaved as a better risk predictor. In our review (including approximately 3.6 million individuals), higher GFR values related to increased mortality risk varied from 106.6 to 113.7 ml/min, which are usually not considered risk values for standard guidelines in non-albuminuric patients. However, the lack of consensus on a GF cutoff value, as well as its variability due to sex and progressive reduction with age, affect the knowledge of this serious phenomenon in clinical practice. Although the elderly population is not exempted from the effects of GHF, the search for this phenomenon should be intensified in middle-aged populations because of their lower disease burden, where this situation may be more evident, and the possibility of reversing the consequences is greater. A population group often considered healthy includes obese people, essential hypertensives, smokers, and carriers of fatty liver, where the GHF phenomenon is frequent and is associated with CV disease, kidney disease, and higher mortality. Increasing its visibility by the medical community is essential to reduce the effects of GHF, emphasizing more frequent controls and implementing general measures that include strict control of hypertension, Na restriction, rich in vegetables diets and increased physical activity. Initiatives to confirm the beneficial effects of sodium-glucose cotransporter-2 inhibitors to treat isolated GHF would be an important breakthrough in reducing the severe consequences of this phenomenon.

Abstract
Stroke is a disease with high incidence, mortality and disability rates. It is also the main cause of adult disability in developed countries. Stroke is often caused by small emboli on the inner wall of the blood vessels supplying the brain, which can lead to arterial embolism, and can also be caused by cerebrovascular or thrombotic bleeding. With the exception of recombinant tissue plasminogen activator (rt-PA), which is a thrombolytic drug used to recanalize the occluded artery, most treatments have been demonstrated to be ineffective. Stroke can also induce peripheral organ damage. Most stroke patients have different degrees of injury to one or more organs, including the lung, heart, kidney, spleen, gastrointestinal tract and so on. In the acute phase of stroke, severe inflammation occurs in the brain, but there is strong immunosuppression in the peripheral organs, which greatly increases the risk of peripheral organ infection and aggravates organ damage. Nonneurological complications of stroke can affect treatment and prognosis, may cause serious short-term and long-term consequences and are associated with prolonged hospitalization and increased mortality. Many of these complications are preventable, and their adverse effects can be effectively mitigated by early detection and appropriate treatment with various medical measures. This article reviews the pathophysiological mechanism, clinical manifestations and treatment of peripheral organ injury after stroke.

Abstract
BackgroundIncreasing studies have focused on the predictive value of high estimated glomerular filtration rate (eGFR) on cardiovascular diseases and mortality; however, the association between high eGFR with cognitive function is still not established. Thus, this study aimed to determine the co-relationship between high eGFR and cognitive performance in the hypertensive population.MethodsWe conducted a baseline cross-sectional study using data from the China H-type Hypertension Registry study. Mini-Mental State Examination (MMSE) assessment was performed to evaluate the cognitive function scale, and serum creatinine was collected to estimate eGFR level. Different MMSE cutoff values were applied in participants with the various educational background to define dementia: <24 in participants with secondary school and above education setting, <20 in those with primary school, and <17 in illiterate participants.ResultsA total of 9,527 hypertensive adults with mean age 63.7 ± 9.8 years and 67% female gender were analyzed. The eGFR cutoff value of 71.52 ml/min/1.73 m2 was found after adjusting for potential covariates in a threshold effect analysis. The MMSE increased significantly with the increment of eGFR (β, 0.27; 95% CI: 0.12–0.41) in participants with eGFR < 71.52 ml/min/1.73 m2 and decreased (β, −0.28; 95% CI: −0.39 to −0.17) in participants with eGFR ≥ 71.52 ml/min/1.73 m2. Individuals with eGFR ≥ 85 ml/min/1.73 m2 have an elevated risk of cognitive impairment than those with eGFR of 65–75 ml/min/1.73 m2. Subgroup analysis showed that a greater reduction degree of MMSE was observed in female individuals and those who had body mass index (BMI) ≥ 24 kg/m2 among participants with eGFR ≥ 71.52 ml/min/1.73 m2.ConclusionOur findings observed an inverted U-shaped relationship between eGFR and cognitive function. Both the low and high levels of eGFR were independently associated with worse cognitive assessment in the hypertensive population.

Abstract
Hyperfiltration is an important underlying cause of glomerular dysfunction associated with several systemic and intrinsic glomerular conditions leading to chronic kidney disease (CKD). These include obesity, diabetes, hypertension, focal segmental glomerulosclerosis (FSGS), congenital abnormalities and reduced renal mass (low nephron number). Hyperfiltration-associated biomechanical forces directly impact the cell membrane, generating tensile and fluid flow shear stresses in multiple segments of the nephron. Ongoing research suggests these biomechanical forces as the initial mediators of hyperfiltration-induced deterioration of podocyte structure and function leading to their detachment and irreplaceable loss from the glomerular filtration barrier. Membrane lipid-derived polyunsaturated fatty acids (PUFA) and their metabolites are potent transducers of biomechanical stress from the cell surface to intracellular compartments. Omega-6 and ω-3 long-chain PUFA from membrane phospholipids generate many versatile and autacoid oxylipins that modulate pro-inflammatory as well as anti-inflammatory autocrine and paracrine signaling. We advance the idea that lipid signaling molecules, related enzymes, metabolites and receptors are not just mediators of cellular stress but also potential targets for developing novel interventions. With the growing emphasis on lifestyle changes for wellness, dietary fatty acids are potential adjunct-therapeutics to minimize/treat hyperfiltration-induced progressive glomerular damage and CKD.

Abstract
BACKGROUND AND AIMS Prior studies have shown an association between positive urinary protein and an elevated risk of long-term mortality in patients with acute ischemic stroke (AIS); however, data on the short-term prognostic significance of urinary protein and urinary ketone bodies in patients with AIS is sparse. METHODS AND RESULTS A total of 2842 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included. Patients were divided into urinary protein positive and negative, urinary ketone bodies positive and negative by urine dipstick. Cox and logistic regression models were used to estimate the effect of urinary protein and urinary ketone bodies on all cause in-hospital mortality and poor outcome upon discharge (modified Rankin Scale score ≥3) in AIS patients. Patients with positive urinary protein was associated with a 2.74-fold and 1.62-fold increase in the risk of in-hospital mortality (adjusted HR 2.74; 95% CI, 1.54-4.89; P-value = 0.001) and poor outcome upon discharge (aOR, 1.62; 95% CI 1.26-2.08; P-value <0.001) in comparison to negative urinary protein after adjusting for potential covariates. Moreover, Patients with positive urinary ketone bodies was associated with 2.11-fold in the risk of poor outcome upon discharge (aOR 2.11; 95% CI 1.52-2.94; P-value <0.001) but not in-hospital mortality (P-value = 0.066) after adjusting for potential covariates. CONCLUSIONS Urinary protein at admission was independently associated with in-hospital mortality and poor functional outcome at hospital discharge in acute stroke patients and urinary ketone bodies also associated with poor functional outcome at hospital discharge.

Renal Impairment and Risk of Acute Stroke: The INTERSTROKE Study. Neuroepidemiology 2021; 55:206-215. [PMID: 33951632 DOI: 10.1159/000515239] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/11/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Previous studies reported an association of renal impairment with stroke, but there are uncertainties underpinning this association. AIMS We explored if the association is explained by shared risk factors or is independent and whether there are regional or stroke subtype variations. METHODS INTERSTROKE is a case-control study and the largest international study of risk factors for first acute stroke, completed in 27 countries. We included individuals with available serum creatinine values and calculated estimated glomerular filtration rate (eGFR). Renal impairment was defined as eGFR <60 mL/min/1.73 m2. Multivariable conditional logistic regression was used to determine the association of renal function with stroke. RESULTS Of 21,127 participants, 41.0% were female, the mean age was 62.3 ± 13.4 years, and the mean eGFR was 79.9 ± 23.5 mL/min/1.73 m2. The prevalence of renal impairment was higher in cases (22.9% vs. 17.7%, p < 0.001) and differed by region (p < 0.001). After adjustment, lower eGFR was associated with increased odds of stroke. Renal impairment was associated with increased odds of all stroke (OR 1.35; 95% CI: 1.24-1.47), with higher odds for intracerebral hemorrhage (OR 1.60; 95% CI: 1.35-1.89) than ischemic stroke (OR 1.29; 95% CI: 1.17-1.42) (pinteraction 0.12). The largest magnitudes of association were seen in younger participants and those living in Africa, South Asia, or South America (pinteraction < 0.001 for all stroke). Renal impairment was also associated with poorer clinical outcome (RRR 2.97; 95% CI: 2.50-3.54 for death within 1 month). CONCLUSION Renal impairment is an important risk factor for stroke, particularly in younger patients, and is associated with more severe stroke and worse outcomes.

Abstract
BACKGROUND Stroke is prevalent in patients with chronic kidney disease (CKD) and is associated with high mortality, but the causes of death after stroke among different CKD stages are not well known. AIMS We aimed to investigate whether the severity of CKD would impact on the causes of death after first-ever stroke. METHODS This retrospective multicenter cohort study included stoke patients with CKD between 2007 and 2012. The cause of death and date of death were ascertained by linking the National Death Registry Database of Taiwan. Clinical outcomes, 1-month, and 1-year mortality rates, and major causes of death were compared according to five CKD stages (G1 to G5) in the ischemic and hemorrhagic stroke separately. RESULTS Of these patients, 9,878 were first-ever ischemic stroke (IS) patients, and 1,387 were first-ever hemorrhagic stroke (HS) patients. Patients with CKD G5 had the highest one-year mortality rate with hazard ratio 5.28 [95%CI, 3.94-7.08] in IS and 3.03 [95%CI, 2.03-4.54] in HS when compared to G1 patients. Leading causes of one-year death after IS were stroke, cancer, and pneumonia in early (G1-3) CKD patients, while diabetes mellitus, CKD, and stroke itself contributed to the major mortality in CKD G5 patients. An inverse association between eGFR decrement and the proportion of deaths caused by stroke itself was observed in CKD G2-5 patients after IS. Stroke was the leading cause of one-year death among all CKD patients after HS. CONCLUSIONS Asides from high mortality, late-stage CKD patients had different causes of death from early CKD patients after stroke. This study highlights the need to imply different treatment strategies in late-stage CKD post-stroke patients to improve their prognosis.

Abstract
Renal hyperfiltration, defined as an increased glomerular filtration rate above normal values, is associated with early phases of kidney disease in the setting of various conditions such as obesity and diabetes. Although it is recognized that glomerular hyperfiltration, that is, increased filtration per nephron unit (usually studied at low glomerular filtration levels and often referred to as single nephron hyperfiltration), is a risk factor for the progression of chronic kidney disease, the implications of having renal hyperfiltration for cardiovascular disease and mortality risk are incompletely understood. Recent evidence from diverse populations, including healthy individuals and patients with diabetes or established cardiovascular disease, suggests that renal hyperfiltration is associated with a higher risk of cardiovascular disease and all-cause mortality. In this review, we critically summarize the existing studies, discuss possible mechanisms, and describe the remaining gaps in our knowledge regarding the association of renal hyperfiltration with cardiovascular disease and mortality risk.

Abstract
Background and Purpose- Kidney dysfunction is common among patients hospitalized for ischemic stroke. Understanding the association of kidney disease with poststroke outcomes is important to properly adjust for case mix in outcome studies, payment models and risk-standardized hospital readmission rates. Methods- In this cohort study of fee-for-service Medicare patients admitted with ischemic stroke to 1579 Get With The Guidelines-Stroke participating hospitals between 2009 and 2014, adjusted multivariable Cox proportional hazards models were used to determine the independent associations of estimated glomerular filtration rate (eGFR) and dialysis status with 30-day and 1-year postdischarge mortality and rehospitalizations. Results- Of 204 652 patients discharged alive (median age [25th-75th percentile] 80 years [73.0-86.0], 57.6% women, 79.8% white), 48.8% had an eGFR ≥60, 26.5% an eGFR 45 to 59, 16.3% an eGFR 30 to 44, 5.1% an eGFR 15 to 29, 0.6% an eGFR <15 without dialysis, and 2.8% were receiving dialysis. Compared with eGFR ≥60, and after adjusting for relevant variables, eGFR <45 was associated with increased 30-day mortality with the risk highest among those with eGFR <15 without dialysis (hazard ratio [HR], 2.09; 95% CI, 1.66-2.63). An eGFR <60 was associated with increased 1-year poststroke mortality that was highest among patients on dialysis (HR, 2.65; 95% CI, 2.49-2.81). Dialysis was also associated with the highest 30-day and 1-year rehospitalization rates (HR, 2.10; 95% CI, 1.95-2.26 and HR, 2.55; 95% CI, 2.44-2.66, respectively) and 30-day and 1-year composite of mortality and rehospitalization (HR, 2.04; 95% CI, 1.90-2.18 and HR, 2.46; 95% CI, 2.36-2.56, respectively). Conclusions- Within the first year after index hospitalization for ischemic stroke, eGFR and dialysis status on admission are associated with poststroke mortality and hospital readmissions. Kidney function should be included in risk-stratification models for poststroke outcomes.

Abstract
Objective This study was performed to evaluate the potential predictors of poor outcomes associated with diabetes-specific microvascular pathologies and to analyze their influence on clinical outcomes by adjusting for other well-known prognostic factors in patients with acute ischemic stroke. Methods We analyzed 1389 consecutive adult patients with acute ischemic stroke and explored the relationship among clinical characteristics, laboratory measurements, imaging findings, and 6-month functional outcomes. Results The final study population comprised 216 patients with both acute ischemic stroke and diabetes mellitus who were followed up for 6 months. A multiple logistic regression analysis of poor outcomes revealed the following independent predictors: leukoaraiosis severity [odds ratio (OR), 7.38; 95% confidence interval (CI), 1.40–38.86, per 1-point increase), diabetic nephropathy (OR, 10.66; 95% CI, 1.10–103.43), and the admission National Institutes of Health stroke scale score (OR, 2.58; 95% CI, 1.36–4.92 per 1-point increase). In this model, admission hyperglycemia and intracerebral hemorrhagic transformation were not independent prognostic predictors. Conclusion Microvascular complications (such as nephropathy) caused by diabetes mellitus predict an unfavorable clinical outcome after acute ischemic stroke. Diabetic nephropathy may partly affect post-stroke prognosis by means of exacerbating leukoaraiosis.

Abstract
BACKGROUND Recent studies in Caucasians with transient ischaemic attack or ischaemic stroke have demonstrated significant age-specific associations between cerebral small vessel disease (SVD) burden on magnetic resonance imaging and renal impairment. We aimed to validate these findings in a large cohort of Chinese with ischaemic stroke. METHODS In 959 Chinese with ischaemic stroke who received a brain magnetic resonance imaging at the University of Hong Kong, we determined the age-specific associations of renal impairment (glomerular filtration rate < 60 mL/min/1.73 m2) with neuroimaging markers of SVD as well as with the SVD score. RESULTS Although renal impairment was associated with the SVD score in univariate analysis in all patients (odds ratio 1.61, 95% confidence interval 1.24-2.09, P < .0001), these associations were attenuated after adjusting for age and sex (P = .38). Similar findings were noted in patients with ischaemic stroke due to SVD and non-SVD subtypes. However, in 222 of 959 patients aged <60, renal impairment was independently associated with an increasing microbleed (adjusted odds ratio 6.82, 2.26-20.59), subcortical (4.97, 1.62-15.24) periventricular white matter hyperintensity (3.96, 1.08-14.51) and global SVD burden (3.41, 1.16-10.04; all P < .05) even after adjusting for age, sex, and vascular risk factors. Nevertheless, there were no associations between renal impairment and individual neuroimaging markers of SVD nor with the SVD score in patients aged ≥60 after adjusting for age and sex (all P > .05). CONCLUSIONS In Chinese with ischaemic stroke, renal impairment was independently associated with microbleed, white matter hyperintensity and global SVD burden in individuals aged <60, but not in those aged ≥60, suggesting that there may be shared susceptibilities to premature systemic disease.

Abstract
BACKGROUND Previous studies have shown the potential interactions between cerebrovascular diseases and microalbuminuria. However, the relationship between urine microalbumin and acute lacunar infarction caused by cerebral small vessel disease (CSVD) remains unknown. METHODS The clinical data of 148 patients with acute lacunar infarction admitted to the Department of Neurology, Shengjing Hospital of China Medical University between April 2016 and April 2017 were analyzed. They were divided into either a CSVD group (n = 70) or a cerebral large vessel disease (CLVD) group (n = 78) according to their carotid artery B-mode ultrasonography and head magnetic resonance angiography (MRA) findings. The concentration of urinary microalbumin in both groups was determined. Statistic analysis was conducted using SAS 9.1 software (North Carolina state university, USA). A Logistic regression analysis was used to determine the independent risk factors for acute lacunar infarction caused by CSVD. RESULTS The concentration of urine microalbumin in the CSVD group (23 ± 12 mg/L) was significantly lower than that in the CLVD group (29 ± 15 mg/L) (p < 0. 01). However, there was an increasing trend for the proportion of patients with urine microalbumin concentration 10- < 30 mg/L (34.3%) in the CSVD group compared with the CLVD group (19.2%). Logistic regression analysis showed that microalbuminuria (10- < 30 mg/L) was independently associated with acute lacunar infarction caused by CSVD (OR = 3.582; 95% CI 1.347~6.274; p < 0.01). CONCLUSIONS These findings demonstrate that in patients with acute lacunar infarction, slightly increased microalbuminuria seems to be a potential clinical marker for CSVD. The presence of microalbuminuria early may help to differentiate CSVD from stroke subtypes.

Abstract
BACKGROUND AND AIMS Serum cystatin C (CysC) is associated with the risk of ischemic stroke and may predict cardiovascular events and death after ischemic stroke onset. However, the association between serum CysC and functional outcome in ischemic stroke patients remains unclear, and whether lipid component level influences the relationship between them has not been studied. METHODS A total of 3348 ischemic patients from China Antihypertensive Trial in Acute Ischemic Stroke were included in the study. Serum CysC was used to calculate estimated glomerular filtration rate (eGFRCysC) at baseline. The primary outcome was poor functional outcome (modified Rankin Scale score ≥3) at one year after ischemic stroke. Secondary outcomes were death, stroke recurrence, vascular events and combination of the aforementioned outcomes. RESULTS The association between eGFRCysC and primary outcome was appreciably modified by low-density lipoprotein cholesterol (LDL-C) (pinteraction = 0.048). Low eGFRCysC was associated with primary outcome only in ischemic stroke patients with LDL-C ≥4.14 mmol/l rather than all patients. The multivariable adjusted odds ratio (95% confidence interval) of poor functional outcome associated with low eGFRCysC was 3.94 (1.04-14.98) and a positive linear dose-response relationship between them was observed among patients with LDL-C ≥4.14 mmol/l (p for linearity = 0.021). Subgroup analyses further confirmed these associations. There was no association between eGFR based on serum creatinine and poor functional outcome of stroke. CONCLUSIONS Low eGFRCysC may be an independent predictor for 1-year poor functional outcome in ischemic stroke patients with LDL-C ≥4.14 mmol/l. Further studies are needed to replicate our findings and to clarify the potential mechanisms.

Abstract
OBJECTIVE Although patients with type 1 diabetes have a poor prognosis after a stroke, predictors of survival after an incident stroke in these patients are poorly studied. RESEARCH DESIGN AND METHODS In this observational study, a total of 144 patients of 4,083 with type 1 diabetes from the Finnish Diabetic Nephropathy (FinnDiane) Study suffered an incident stroke in 1997-2010, and were followed for a mean 3.4 ± 3.1 years after the stroke. Information was recorded on hard cardiovascular events and death as a result of cardiovascular or diabetes-related cause, collectively referred to as vascular composite end point. Information was collected from medical records, death certificates, and the National Care Register of Health Care. Predictors at the time of the incident stroke were studied for the end points. RESULTS During follow-up, 104 (72%) patients suffered a vascular composite end point. Of these, 33 (32%) had a recurrent stroke, 33 (32%) a hard cardiovascular event, and 76 (53%) died of cardiovascular or diabetes-related causes, with an overall 1-year survival of 76% and 5-year survival of 58%. The predictors of a vascular composite end point were hemorrhagic stroke subtype (hazard ratio 2.03 [95% CI 1.29-3.19]), as well as chronic kidney disease stage 2 (2.48 [1.17-5.24]), stage 3 (3.04 [1.54-6.04]), stage 4 (3.95 [1.72-9.04]), and stage 5 (6.71 [3.14-14.34]). All-cause mortality increased with deteriorating kidney function. CONCLUSIONS Patients with type 1 diabetes with an incident stroke have a poor cardiovascular prognosis and a high risk of all-cause mortality. In particular, hemorrhagic stroke subtype and progression of diabetic kidney disease conveys worse outcome.

Abstract
Chronic kidney disease (CKD) is gradually recognized as an independent risk factor for cardiovascular and cardio-/cerebrovascular disease. This study aimed to examine the association of the estimated glomerular filtration rate (eGFR) and clinical outcomes at 3 months after the onset of ischemic stroke in a hospitalized Chinese population.Totally, 972 patients with acute ischemic stroke were enrolled into this study. Modified of Diet in Renal Disease (MDRD) equations were used to calculate eGFR and define CKD. The site and degree of the stenosis were examined. Patients were followed-up for 3 months. Endpoint events included all-cause death and newly ischemic events. The multivariate logistic model was used to determine the association between renal dysfunction and patients' outcomes.Of all patients, 130 patients (13.4%) had reduced eGFR (<60 mL/min/1.73 m), and 556 patients had a normal eGFR (≥90 mL/min/1.73 m). A total of 694 patients suffered from cerebral artery stenosis, in which 293 patients only had intracranial artery stenosis (ICAS), 110 only with extracranial carotid atherosclerotic stenosis (ECAS), and 301 with both ICAS and ECAS. The patients with eGFR <60 mL/min/1.73m had a higher proportion of death and newly ischemic events compared with those with a relatively normal eGFR. Multivariate analysis revealed that a baseline eGFR <60 mL/min/1.73 m increased the risk of mortality by 3.089-fold and newly ischemic events by 4.067-fold. In further analysis, a reduced eGFR was associated with increased rates of mortality and newly events both in ICAS patients and ECAS patients. However, only an increased risk of newly events was found as the degree of renal function deteriorated in ICAS patients (odds ratio = 8.169, 95% confidence interval = 2.445-14.127).A low baseline eGFR predicted a high mortality and newly ischemic events at 3 months in ischemic stroke patients. A low baseline eGFR was also a strong independent predictor for newly ischemic events in ICAS patients.

Abstract
Cerebrovascular disease and stroke are very common at all stages of chronic kidney disease (CKD), likely representing both shared risk factors as well as synergy among risk factors. More subtle ischemic brain lesions may be particularly common in the CKD population, with subtle manifestations including cognitive impairment. For individuals with nondialysis CKD, the prevention, approach to, diagnosis, and management of stroke is similar to the general, non-CKD population. For individuals with end-stage renal disease, far less is known regarding strategies to prevent stroke. Stroke prophylaxis using warfarin in dialysis patients with atrial fibrillation in particular remains of uncertain benefit. End-stage renal disease patients can be managed aggressively in the setting of acute stroke. Outcomes after stroke at all stages of CKD are poor, and improving these outcomes should be the subject of future clinical trials.

Abstract
Background: In about 30% of young stroke patients, no cause can be identified. In elderly patients, kidney dysfunction has been suggested as a contributing risk factor for mortality as well as stroke. There are hypotheses that novel non-traditional risk factors, like chronic inflammation and oxidative stress, are involved in chronic kidney disease, affecting the cerebral microvasculature that would in turn lead to stroke. Our objective is to investigate the influence of kidney dysfunction on long-term mortality and incident vascular events after stroke in young adults aged 18 through 50 and if this relationship would be independent of other cardiovascular risk factors. Methods: We prospectively included 460 young stroke patients with an ischemic stroke or transient ischemic attack admitted to our department between January 1, 1980 and November 1, 2010. Follow-up was done between 2014 and 2015. Estimated glomerular filtration rate (eGFR) was calculated from baseline creatinine levels and was divided in 3 subgroups: eGFR <60, 60-120 and >120 ml/min/1.73 m2. Cox proportional hazard models were used to determine the effect of kidney dysfunction on mortality and incident vascular events, adjusting for cardiovascular risk factors. Results: An eGFR <60 (HR 4.6; 95% CI 2.6-8.2) was associated with an increased risk of death and an increased risk of incident stroke (HR 4.1; 95% CI 1.9-9.0) independent of cardiovascular risk factors, but it was not associated with other vascular events. The point estimate for the 15-year cumulative mortality was 70% (95% CI 46-94) for patients with a low eGFR, 24% (95% CI 18-30) for patients with a normal eGFR and 30% (95% CI 12-48) for patients with a high eGFR. The point estimate for the 15-year cumulative risk of incident stroke was 45% (95% CI 16-74) for patients with a low eGFR, 13% (95% CI 9-17) for patients with a normal eGFR and 8% (95% CI 0-18) for patients with a high eGFR. Conclusions: Kidney dysfunction is related to long-term mortality and stroke recurrence, but not to incident cardiovascular disease, on average 11 years after young stroke. This warrants a more intensive follow-up of young stroke patients with signs of kidney dysfunction in the early phase. In addition, the clear association between kidney dysfunction and incident stroke seen in our young stroke population might be a first step in the recognition of kidney dysfunction as a new risk factor for the development of stroke at young age. Also, it can lead to new insights in the etiological differences between cardiovascular and cerebrovascular disease.

Abstract
Urea is generated by the urea cycle enzymes, which are mainly in the liver but are also ubiquitously expressed at low levels in other tissues. The metabolic process is altered in several conditions such as by diets, hormones, and diseases. Urea is then eliminated through fluids, especially urine. Blood urea nitrogen (BUN) has been utilized to evaluate renal function for decades. New roles for urea in the urinary system, circulation system, respiratory system, digestive system, nervous system, etc., were reported lately, which suggests clinical significance of urea.

Abstract
Background. Frequency and impact of medical complications on short-term mortality in young patients with intracerebral hemorrhage (ICH) have gone unstudied. Methods. We reviewed data of all first-ever nontraumatic ICH patients between 16 and 49 years of age treated in our hospital between January 2000 and March 2010 to identify medical complications suffered. Logistic regression adjusted for known ICH prognosticators was used to identify medical complications associated with mortality. Results. Among the 325 eligible patients (59% males, median age 42 [interquartile range 34–47] years), infections were discovered in 90 (28%), venous thrombotic events in 13 (4%), cardiac complications in 4 (1%), renal failure in 59 (18%), hypoglycemia in 15 (5%), hyperglycemia in 165 (51%), hyponatremia in 146 (45%), hypernatremia in 91 (28%), hypopotassemia in 104 (32%), and hyperpotassemia in 27 (8%). Adjusted for known ICH prognosticators and diabetes, the only independent complication associated with 3-month mortality was hyperglycemia (plasma glucose >8.0 mmol/L) (odds ratio: 5.90, 95% confidence interval: 2.25–15.48, P < 0.001). Three or more separate complications suffered also associated with increased mortality (7.76, 1.42–42.49, P = 0.018). Conclusions. Hyperglycemia is a frequent complication of ICH in young adults and is independently associated with increased mortality. However, multiple separate complications increase mortality even further.

Abstract
Background The small vessel disease (SVD) that appears in the brain may be part of a multisystem disorder affecting other vascular beds such as the kidney and retina. Because renal failure is associated with both stroke and white matter hyperintensities we hypothesised that small vessel (lacunar) stroke would be more strongly associated with renal failure than cortical stroke. Therefore, we performed a systematic review and meta-analysis to establish first if lacunar stroke was associated with the renal function, and second, if cerebral small vessel disease seen on the MRI of patients without stroke was more common in patients with renal failure. Methods We searched Medline and EMBASE for studies in adults with cerebral SVD (lacunar stroke or white matter hyper intensities (WMH) on Magnetic Resonance Imaging (MRI)), in which renal function was assessed (estimated glomerular filtration rate (eGFR) or proteinuria). We extracted data on SVD diagnosis, renal function, demographics and comorbidities. We performed two meta-analyses: first, we calculated the odds of renal impairment in lacunar (small vessel) ischaemic stroke compared to other ischaemic stroke subtypes (non-small vessel disease); and second, we calculated the odds of renal impairment in non-stroke individuals with WMH on MRI compared to individuals without WMH. We then performed a sensitivity analysis by excluding studies with certain characteristics and repeating the meta-analysis calculation. Results After screening 11,001 potentially suitable titles, we included 37 papers reporting 32 studies of 20,379 subjects: 15 of stroke patients and 17 of SVD features in non-stroke patients. To diagnose lacunar stroke, 13/15 of the studies used risk factor-based classification (none used diffusion-weighted MRI). 394/1,119 (35%) of patients with lacunar stroke had renal impairment compared with 1,443/4,217 (34%) of patients with non-lacunar stroke, OR 0.88, (95% CI 0.6-1.30). In individuals without stroke the presence of SVD was associated with an increased risk of renal impairment (whether proteinuria or reduced eGFR) OR 2.33 (95% CI 1.80-3.01), when compared to those without SVD. After adjustment for age and hypertension, 15/21 studies still reported a significant association between renal impairment and SVD. Conclusion We found no specific association between renal impairment and lacunar stroke, but we did find that in individuals who had not had a stroke, having more SVD features on imaging was associated with a worse renal function, which remained significant after controlling for hypertension. However, this finding does not exclude a powerful co-associate effect of age or vascular risk factor exposure. Future research should subtype lacunar stroke sensitively and control for major risk factors.

Abstract
BACKGROUND the impact of estimated glomerular filtration rate (eGFR) on stroke clinical outcomes remains controversial. We examined the association between eGFR and all-cause mortality, recurrent stroke, and stroke disability in patients with acute ischaemic stroke. METHODS we analysed 8865 patients with acute ischaemic stroke in the China National Stroke Registry (CNSR) between September 2007 and August 2008. Multivariate logistic regression analysis was used to evaluate the association between eGFR and 1-year all-cause mortality, recurrent stroke, and stroke disability. Low eGFR was defined as <45 ml/min/1.73 m(2). RESULTS of 8865 acute ischaemic stroke patients included in the analysis, eGFR of <45 ml/min/1.73 m(2) occurred in 394 (4.4%), eGFR of 45-59 ml/min/1.73 m(2) in 675 (7.6%), eGFR of 60-89 ml/min/1.73 m(2) in 3533 (39.9%), and eGFR of ≥90 ml/min/1.73 m(2) in 4263 (48.1%) at baseline. Patients with reduced renal function were more likely to die, experience recurrent stroke or have stroke disability than patients with preserved renal function. After adjusting for both demographic and clinical risk factors, an eGFR of <45 ml/min/1.73 m(2) was independently associated with 1-year all-cause mortality (OR: 2.65; 95% CI: 1.95-3.59) and recurrent stroke (OR: 1.97; 95% CI: 1.51-2.56) but not for stroke disability defined as modified Rankin Score of 2-6 (OR: 1.26; 95% CI: 0.95-1.67). These results were consistent in stratified analyses by age, diabetes or hypertension. CONCLUSIONS a low eGFR was associated with increased risks of all-cause mortality and recurrent stroke independent of the traditional vascular risk factors in Chinese stroke patients.

Abstract
Although overall stroke incidence has been declining in developed countries, there is evidence that stroke in the young is increasing. Increasing incidence may be particularly pronounced among minorities in whom historically a higher burden of stroke has been reported. Compared with older adults, time spent with disability is longer for those affected at younger ages, and new data suggests that among 30-day young adult stroke survivors, increased mortality persists for as long as 20 years. Stroke in young adults is often missed by less experienced clinicians due to its unexpectedness, leading to lost opportunities for intervention. The causes and risk factors for stroke in the young are often rare or undetermined, but young adults with stroke also have a high burden of traditional cardiovascular risk factors, including hypertension, diabetes, obesity, and substance abuse. Disseminating awareness and promoting research on young adult stroke are steps towards reducing the burden of stroke.

AIM: To investigate the effects of hypertonic saline in the neurocritical care population.
METHODS: We retrospectively reviewed our hospital’s use of hypertonic saline (HS) since March of 2005, and prospectively since October 2010. Comparisons were made between admission diagnoses, creatinine change (Cr), and HS formulation (3% NaCl, 3% NaCl/sodium acetate mix, and 23.4% NaCl) to patients receiving normal saline or lactated ringers. The patients (n = 1329) of the retrospective portion were identified. The data presented represents the first 230 patients with data.
RESULTS: Significant differences in Acute Physiology and Chronic Health Evaluation II scores and Glasgow Coma Scale scores occurred between different saline formulations. No significant correlation of Cl- or Na+ with Cr, nor with saline types, occurred. When dichotomized by diagnosis, significant correlations appear. Traumatic brain injury (TBI) patients demonstrated moderate correlation between Na+ and Cr of 0.45. Stroke patients demonstrated weak correlations between Na+ and Cr, and Cl- and Cr (0.19 for both). Patients receiving HS and not diagnosed with intracerebral hemorrhage, stroke, subarachnoid hemorrhage, or TBI demonstrated a weak but significant correlation between Cl- and Cr at 0.29.
CONCLUSION: Cr directly correlates with Na+ or Cl- in stroke, Na+ in TBI, and Cl- in other populations. Prospective comparison of HS and renal function is needed.

Abstract
Background and purpose Renal dysfunction (i.e. a reduced estimated glomerular filtration rate, eGFR) is commonly found in hospitalized stroke patients but its associations with Patients' characteristics and outcome require further investigation. Methods We linked clinical data from stroke patients enrolled between 2005 and 2008 into two prospective hospital registers with routine laboratory eGFR data. The eGFR was calculated using the Modification of Diet in Renal Disease method and renal dysfunction was defined as <60 ml/min/1·73 m2. In addition we systematically reviewed studies investigating the association between eGFR and outcome after stroke. Results Of 2520 patients who had an eGFR measured on admission hospital, 805 (32%) had renal dysfunction. On multivariate analysis, renal dysfunction was significantly less likely in those with a predicted good outcome (OR 0·27, 95% CI 0·21, 0·36) based on the well-validated six simple variable model. After adjustment for other predictive factors, stroke patients with renal dysfunction were more likely to die in hospital compared with those without (odds ratio 1·59, 95% confidence intervals 1·26, 2·00). Of the 31 studies involving 41 896 participants included in the systematic review, 18 studies found that low eGFR was an independent predictor of death and 6 reported a significant association with death and disability. Conclusion Our findings suggest that renal dysfunction on admission is common and associated with poor outcomes over the first year. Further work is required to establish to what extent these associations are causal and whether treating impaired renal function improves outcomes.

Abstract
BACKGROUND AND PURPOSE This study was conducted to investigate the association of cerebral white matter disease (WMD) on MRI with vascular risk factors and laboratory findings in consecutive first acute ischemic stroke patients. METHODS Acute ischemic stroke patients underwent MRI ≤24 hours after stroke onset and follow-up on day 2. WMD was scored on fluid attenuated inversion recovery MRI according to the Wahlund score. Vascular risk factors and laboratory parameters were assessed during hospital stay. Univariate and multiple logistic regression analyses were performed. RESULTS We included 512 patients with first acute ischemic stroke (mean age, 68.5 [SD, 13.2] years; 192 women (37.5%); median National Institutes of Health Stroke Scale on admission, 3 [interquartile range, 1-6]; and median Wahlund score, 4 [interquartile range, 2-9]). WMD was present in 460 (89.8%) patients. In univariate analysis, age, arterial hypertension, reduced estimated glomerular filtration rate, hemoglobin A1c (HbA1c) levels, diabetes mellitus, and female sex were associated with the presence of WMD (P<0.05). In multiple regression analysis, age, arterial hypertension, and elevated levels of HbA1c (P<0.05) remained independently associated with the extent of WMD. CONCLUSIONS Among known risk factors, higher levels of HbA1c were associated with cerebral WMD in stroke patients. This may suggest that chronic disturbance of glycemia measured by HbA1c plays a role in the pathophysiology of WMD. CLINICAL TRIAL REGISTRATION URL http://www.clinicaltrials.gov.

Abstract
BACKGROUND Low estimated glomerular filtration rate (eGFR) has been linked to higher risk of primary stroke, but little is known about the relation of low eGFR to recurrent vascular risk after stroke. B Vitamin therapy has been used to lower homocysteine levels, but its interaction with kidney function on future major vascular events has not been assessed. The objective of this study was to conduct a secondary analysis based on the Vitamin Intervention for Stroke Prevention (VISP) trial to clarify these issues. STUDY DESIGN In the VISP trial, patients with a prior ischemic stroke were randomly assigned to receive the high- or low-dose B vitamin therapy. The trial did not find a difference between randomly assigned groups. The present study is a secondary analysis of the VISP trial. SETTING & PARTICIPANTS We analyzed the database of a multicenter trial comprising 3,673 patients with recent ischemic stroke who were followed up for 2 years. PREDICTOR We subdivided the cohort based on eGFR into 6 groups (≥105, 90-104, 75-89, 60-74, 45-59, and <45 mL/min/1.73 m²) for the analyses and used eGFR of 60-74 mL/min/1.73 m² as the reference category. Low eGFR was defined as <45 mL/min/1.73 m². OUTCOMES The primary end point for this analysis was major vascular events, defined as the composite of nonfatal ischemic stroke, nonfatal myocardial infarction, and vascular death (whichever event came first). The secondary end point was recurrent ischemic stroke. Also, the effects of high-dose B vitamin treatment on future major vascular events according to baseline eGFR categories were analyzed and reported separately. RESULTS Mean baseline eGFR was 73.9 ± 21.8 (SD) mL/min/1.73 m². 471 major vascular events during an average of 20 months of follow-up, including 300 recurrent strokes, were recorded. Baseline low eGFR was associated with increased risk of major vascular events (HR, 1.83; 95% CI, 1.32-2.52; P < 0.001) and recurrent stroke (HR, 1.53; 95% CI, 1.01-2.32; P = 0.04) after adjustment for traditional vascular risk factors and homocysteine level. At baseline eGFR <45 mL/min/1.73 m², high-dose B vitamin therapy compared to low dose showed a trend of higher risk of future major vascular events (HR, 1.49; 95% CI, 0.95-2.34; P = 0.08). The overall P value for interaction between B vitamin dose and eGFR was not significant (P = 0.6). LIMITATIONS No data for albuminuria. CONCLUSIONS Low eGFR is associated with higher risk of future major vascular events and recurrent stroke after a recent ischemic stroke.

Abstract
Background Limited data exist on the associated factors and correlation of leucocyte count to outcome in young adults with first-ever ischaemic stroke. Aims Our objectives were to investigate factors associated with elevated leucocyte count and whether there is correlation between leucocyte count and short- and long-term outcomes. Methods Of our database of 1008 consecutive patients aged 15 to 49, we included those with leucocyte count measured within the first two days from stroke onset. Outcomes were three-month and long-term disability, death, and vascular events. Linear regression was used to explore baseline variables associated with leucocyte count. Logistic regression and Cox proportional models studied the association between leucocyte count and clinical outcomes. Results In our study cohort of 781 patients (61·7% males; mean age 41·4 years), mean leucocyte count was high: 8·8 ± 3·1 × 109 cells/L (Reference range: 3·4–8·2 × 109 cells/L). Higher leucocyte levels were associated with dyslipidaemia, smoking, peripheral arterial disease, stroke severity, and lesion size. After adjustment for age, gender, relevant risk factors, both continuous leucocyte count and the highest quartile of leucocyte count were independently associated with unfavourable three-month outcome. Regarding events in the long-term (follow-up 8·1 ± 4·2 years in survivors), no association between leucocyte count and the event risks appeared. Conclusions Among young stroke patients, high leucocyte count was a common finding. It was associated with vascular disease and its risk factors as well as severity of stroke, but it was also independently associated with unfavourable three-month outcome in these patients. There was no association with the long-term outcome. [Correction added on 31 October 2013 after first online publication: In the Results section of the Abstract, the cohort of 797 patients in this study was corrected to 781 patients.]

Abstract
Background and Purpose—
We aimed to explore clinical features of young patients with ischemic stroke with no traditional vascular risk factors and to assess the impact of risk factor counts on outcomes.
Methods—
We included 990 patients aged 15 to 49 years with first-ever ischemic stroke followed for a mean of 9.0±3.8 years (survivors). Risk factors were categorized as well-documented and less well-documented. Outcome measures were unfavorable functional outcome (3-month modified Rankin Scale 2–6); recurrent ischemic stroke; myocardial infarction or other arterial noncerebrovascular event; and death from any cause.
Results—
Compared with those with at least 1 well-documented risk factor, the 127 (12.8%) patients without risk factors were younger (median age, 37 versus 44 years;
P
<0.001), likely to be females (54.3% versus 34.9%;
P
<0.001), and they had more frequently a low-risk source of cardioembolism (21.3% versus 8.1%;
P
<0.001), internal carotid artery dissection (12.6% versus 6.4%;
P
=0.011), or vertebral artery dissection (17.3% versus 7.2%;
P
<0.001). The groups had similar 3-month functional outcomes. Patients without well-documented risk factors had less frequently recurrent ischemic strokes (4.7% versus 13.6%; log rank
P
=0.014), noncerebrovascular arterial events (0% versus 6.1%;
P
=0.008), and lower long-term mortality (3.4% versus 14.3%;
P
=0.003) than did those with at least 1 risk factor. Adjusted for demographics and stroke etiology, the number of well-documented risk factors was associated with higher risk for noncerebrovascular events. Increasing count of less well-documented risk factors was, in turn, independently associated with higher long-term mortality.
Conclusions—
In young adults with first-ever ischemic stroke, risk factor counts added independent prognostic information regarding noncerebrovascular events and mortality.
