Abstract
Post-stroke cognitive impairment (PSCI) is a common decline in cognitive abilities that occurs within 3 months after a stroke. During recovery, stroke survivors often experience varying degrees of cognitive decline, with some patients experiencing permanent cognitive deficits. Thus, it is crucial to prioritise recovery and rehabilitation after a stroke to promote optimal protection of and improvement in cognitive function. Honey derived from stingless bees has been linked to various therapeutic properties, including neuroprotective effects. However, scientific evidence for the mechanisms through which these honey supplements enhance cognitive function remains limited. This narrative review aims to provide an overview of the causes of PSCI, current treatments, the biomarkers influencing cognition in post-stroke patients and the potential of stingless bee honey (SBH) as a neuroprotective agent against the progression of PSCI.

Huang X, Deng L, Huang J, Sun J, Wang Q, Mo J, Zhai Z, Nong Y, Lu W. The Ratio of Serum Uric Acid to Glycosylated Haemoglobin as a Predictor of All-Mortality in Elderly Patients with Diabetic Foot Ulcers: A Longitudinal Cohort Study. Diabetes Metab Syndr Obes 2023; 16:2779-2790. [PMID: 37720420 PMCID: PMC10504904 DOI: 10.2147/dmso.s423017] [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] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Accepted: 09/07/2023] [Indexed: 09/19/2023] Open
Abstract
Aim To clarify the relationship between serum uric acid (UA) and glycosylated hemoglobin (UA/HbA1c) ratio and all-cause mortality in patients with diabetic foot ulcers (DFUs). Methods A total of 172 inpatients with DFUs (PEDIS grades 2-4) were eligible for inclusion in this study from 2018 to 2023. This was a retrospective, longitudinal cohort study. All subjects were followed up every 6 months for a median of 60 months. According to the cutoff value of the UA/HbA1c ratio of 39.07 obtained from ROC analysis, the participants were divided into two groups: low-level (≤ 39.07, n = 107) and high-level (> 39.07, n = 65) groups. The correlation between UA/HbA1c ratio and all-cause mortality was also evaluated by Cox regression analysis TheKaplan-Meier survival curve analysis and Log rank tests were used to assess the incidence rates of all-cause mortality. The contribution rate of risk factors was estimated by the population-attributable risk percentage (PAR%) analysis. Results ROC analysis showed that the optimal cutoff values for UA and the UA/HbA1c ratio were 372 μmol/L and 39.07, respectively. Multivariate Cox regression analysis indicated that a high UA/HbA1c ratio (HR =4.63; 95% CI = 2.004-10.7, P < 0.001) was independently associated with a high risk of all-cause mortality in patients with DFUs. Stratified analysis indicated that subjects aged ≥ 60 years had a greater risk of all-cause mortality associated with a high UA/HbA1c ratio (HR = 4.450; 95% CI = 1.711-11.574, P = 0.002). Kaplan-Meier survival analysis showed that all-cause mortality had a significant positive association with a high UA/HbA1c ratio (log-rank, P < 0.001) and a significant negative correlation with the lowered HbA1c level (< 6.5%) after a follow-up of 32 months (log-rank, P < 0.001). The population attributable risk percentage (PAR%) analysis suggested that the contribution rate of the high-level UA/HbA1c ratio to all-cause mortality was 33.7%, which was much greater than the 19.69% of UA. Conclusion In brief, our study showed that for every 1.0% increase in the UA/HbA1c ratio, the all-cause mortality rate in elderly patients with DFUs aged ≥ 60 years increased by 3.45-fold. For elderly patients with DFUs, a safe and effective strategy to reduce all-cause mortality is to strictly control serum UA levels to < 372 μmol/L and appropriately loosen the control goal of HbA1c to ≥ 6.5%.

Control of Diabetes Mellitus and Long-Term Prognosis in Stroke Patients: The Shiga Stroke and Heart Attack Registry. Cerebrovasc Dis 2023; 52:81-88. [PMID: 35921810 PMCID: PMC9909615 DOI: 10.1159/000525648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Accepted: 05/06/2022] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND The relationship between diabetes control status and long-term prognosis after stroke incidence remains unclear. This study aimed to investigate the effect of diabetes status at admission on long-term survival in patients with first-ever stroke. METHODS A retrospective cohort study was conducted based on the Shiga Stroke and Heart Attack Registry in Japan. Patients were classified according to their diabetes status and glycated hemoglobin (HbA1c) value at hospital admission into the following: (1) free of diabetes (no history of diabetes and HbA1c <6.5%); (2) good control (history of diabetes and HbA1c <7%; free of history and 6.5% ≤HbA1c <7%); and (3) poor control (with or without a history of diabetes and HbA1c ≥7%). Multivariable Cox regression models were used to evaluate the association between diabetes status and long-term survival from stroke onset. Additionally, we also evaluated the association between diabetes status and conditional survival, beginning 29 days after stroke onset. RESULTS A total of 6,331 first-ever stroke patients were eligible for this study. Among study patients, the mean (±SD) age was 72.85 ± 13.19 years, and the mean (±SD) follow-up year was 2.76 ± 1.66 years; additionally, 42.09% of patients were women. Among patients with all strokes, considering the free-of-diabetes group as the reference group, the adjusted hazard ratio (95% confidence interval) for mortality was 1.26 (1.10, 1.44) in the good control group and 1.22 (1.05, 1.41) in the poor control group. Among patients with ischemic stroke, the adjusted hazard ratio was 1.24 (1.06, 1.46) in good control group and 1.27 (1.08, 1.50) in poor control group. After excluding patients who died within 28 days, the adjusted hazard ratio for conditional mortality in the poor control group was 1.31 (1.12, 1.54) among all stroke patients and 1.29 (1.08, 1.54) among ischemic stroke patients. No significant associations were observed between diabetic status and long-term mortality in intracerebral hemorrhage patients. CONCLUSIONS The findings suggest that first-ever stroke patients with diabetes exhibited a higher risk of all-cause mortality than those without diabetes, particularly in the overall stroke and ischemic stroke populations. Additionally, in stroke populations after 28 days of onset, high risk of long-term mortality was stated in stroke patients with poor HbA1c control.

Abstract
Diabetes mellitus (DM) is associated with an increased risk of complications in atrial fibrillation (AF). This study aimed to assess the incidence and risks of ischemic stroke and mortality according to baseline HbA1c levels in patients with DM and AF. We conducted a cohort study using Clalit Health Services electronic medical records. The study population included all Clalit Health Services members aged ≥25 years, with the first diagnosis of AF between January 1, 2010, and December 31, 2016, who had a diagnosis of DM. The risk of stroke and all-cause death were compared according to HbA1c levels at the time of AF diagnosis: <7.0%, between 7% and 9%, and ≥9%. A total of 44,451 patients with DM and AF were identified. The median age was 75 years (interquartile 65 to 83), and 52.5% were women. During a mean follow-up of 38 months, higher levels of HbA1c were associated with an increased risk of stroke with a dose-dependent response when compared with patients with HbA1c <7% (Adjusted hazard ratio [aHR] =1.30 [95% confidence interval 1.10 to 2.05] for levels between 7% and 9% and 1.60 (95% confidence interval 1.25 to 2.03) for HbA1c >9%, even after adjusting for CHA2DS2-Vasc risk factors and use of oral anticoagulants. The risk for overall mortality was significantly higher in the HBA1C >9% group (aHR = 1.17 [1.07 to 1.28]). In conclusion, in this cohort of patients with AF and DM, HbA1c levels were associated with the risk of stroke in a dose-dependent manner even after accounting for other recognized risk factors for stroke.

Janssen SM, Connelly DM. The effects of exercise interventions on physical function tests and glycemic control in adults with type 2 diabetes: A systematic review. J Bodyw Mov Ther 2021; 28:283-293. [PMID: 34776154 DOI: 10.1016/j.jbmt.2021.07.022] [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: 07/28/2020] [Revised: 03/06/2021] [Accepted: 07/16/2021] [Indexed: 12/25/2022]
Abstract
INTRODUCTION Regular exercise improves glycemic control and helps to mitigate the decline in strength, mobility, and balance. The 6-min walk test (6MWT), timed up-and-go test (TUG) and the sit-to-stand test (STS) are reliable measures of physical function in adults with type 2 diabetes (T2D). Outcome measures allow physiotherapists to monitor changes in physical function with exercise prescription. METHODS PubMed, CINAHL, EMBASE and Scopus databases and reference lists of relevant reviews were searched for randomized controlled trials (RCTs) relating to exercise and T2D published until June 2020. Studies were included when: (a) participants were adults diagnosed with T2D, (b) exercise was a main intervention and compared to controls, and (c) at least one clinical physical function measure was used to detect changes in aerobic capacity, mobility or strength. RESULTS Eight of 10 RCTs reported either statistically significant between-group (p < 0.05) or within-group (p < 0.05) differences in 6MWT scores. Nonsignificant between-group differences were found in two resistance training RCTs that utilized the TUG test. Three of five RCTs utilizing the STS test reported significant between groups differences (p < 0.05). Seven of 11 RCTs reported statistically significant between-group (p < 0.05) or within-group (p < 0.05) differences in glycated hemoglobin (HbA1c) levels. CONCLUSION Physical function measures may be useful for monitoring aerobic capacity, lower extremity strength and mobility with exercise in patients with T2D. Improvements in 6MWT scores may depend on total volume of exercise (minutes/week ∗ weeks of intervention). However, changes in HbA1c with exercise were variable and may depend on type of exercise.

Abstract
Background Uncomplicated hyperglycaemia is a common presentation in the emergency department (ED). Rapid glucose control is associated with the risk of iatrogenic hypoglycaemia. We sought to determine the safety of a rapid glucose control protocol delivered in a 24-h emergency department observation unit (OU). Methods This is a retrospective chart review of patients admitted to the OU for hyperglycaemia where the assessing clinician deemed there was no other reason for medical admission apart from hyperglycaemia; and that the patient could be safely discharged provided their hyperglycaemia was adequately treated. The rapid glucose control protocol consists of 4–6 hourly glucose monitoring and insulin injections according to a sliding scale. We report the demographics, reduction in glucose values and the incidence of hypoglycaemia in the OU. We also determine the rate of discharge from OU and the rate of hospital admission at 30 days. Results We included 101 patients. The mean age was 53.5 years (95% CI 50.4–56.6) and 64% of patients were male. The mean HbA1c value was 12.8% (95% CI 12.3–13.3). The mean admission and discharge glucose values were 27.2 (95% CI 26.3–28.1) and 13.9 (95% CI 13.2–14.6) mmols/l respectively. There was no incidence of hypoglycaemia in the OU. We successfully discharged 90.1% of the patients from the OU, of which 3 (3.3%) patients were admitted to the hospital within 30 days of discharge. Conclusion ED OU is a safe location to deliver effective management for patients presented with uncomplicated severe hyperglycaemia.

Abstract
Background: Glycated hemoglobin (HbA1c) has emerged as a useful biochemical marker reflecting the average glycemic control over the last 3 months, and the values are not affected by short-term transient changes in blood glucose levels. However, its prognostic value in the acute neurological conditions such as stroke is still not well-established. The present meta-analysis was conducted to assess the relationship of HbA1c with outcomes such as mortality, early neurological complications, and functional dependence in stroke patients. Methods: A systematic search was conducted for the PubMed, Scopus, and Google Scholar databases. Studies, either retrospective or prospective in design that examined the relationship between HbA1c with outcomes of interest and presented the strength of association in the form of adjusted odds ratio/hazard ratios were included in the review. Statistical analysis was done using STATA version 13.0. Results: A total of 22 studies (15 studies on acute ischemic stroke and seven studies on hemorrhagic stroke) were included in the meta-analysis. For patients with acute ischemic stroke, each unit increase in HbA1c was found to be associated with an increased risk of mortality within 1 year, increased risk of poor functional outcome at 3 months, and an increased risk of symptomatic intracranial hemorrhage (sICH) within 24 h of admission. In those with HbA1c ≥ 6.5%, there was an increased risk of mortality within 1 year of admission, increased risk of poor functional outcomes at 3 and 12 months as well as an increased risk of symptomatic intracranial hemorrhage (sICH) within 24 h of admission. In patients with hemorrhagic stroke, each unit increase in HbA1c was found to be associated with increased risk of poor functional outcome within the first 3 months from the time of admission for stroke. In those with HbA1c ≥ 6.5%, there was an increased risk of poor functional outcome at 12 months. Conclusions: The findings indicate that glycated hemoglobin (HbA1c) could serve as a useful marker to predict the outcomes in patients with stroke and aid in the implementation of adequate preventive management strategies at the earliest.

Abstract
AIMS Pre-diabetes is a common condition that affects about 16.4% of Australian adults. Hyperglycaemia is a strong risk factor for the development of stroke. Metformin XR is an approved medication to treat type 2 diabetes in Australia but not pre-diabetes. Additionally, whether it is tolerated following a stroke is unclear. In this pilot study, we aimed to assess the feasibility of Metformin XR in people with stroke and pre-diabetes. METHODS In this PROBE design trial, people who had recent stroke (within 3 months) with pre-diabetes were randomized to either the active arm (n = 13) receiving usual care plus Metformin XR (500 mg daily increased to a total daily dose of 1500 mg) or the control group receiving only usual care (n = 13). At baseline & after four months of intervention, clinical and biomedical characteristics, cardiovascular risk factors and medication data were recorded. At one month and 2.5 months into the study, compliance rateandside effects were determined. RESULTS This trial showed that it is feasible to recruit, retain and monitor participants. However, the compliance rate was low. Adherence to metformin XR was 52% (IQR:42% to 61%) based on the remaining tablets in the container after 4 months of intervention. None of the reported side effects were deemed to be related to the study treatment and no significant differences were observed between the metformin XR and the control group. CONCLUSION Treatment with Metformin XR in participants admitted with stroke and with pre-diabetes is feasible and safe. Strategies are needed to improve adherence in future trials.

Abstract
INTRODUCTION We aimed to evaluate the characteristics of carotid artery plaques and the relationship between intraplaque neovascularization (IPN) and hemoglobin A1c (HbA1c) in patients of <60 years old with diabetes mellitus (DM) by comparison with diabetes ≥60 years of age. METHODS One-hundred-and-one patients with DM were studied into two groups: those <60 and those ≥60 years of age. All the patients underwent standard carotid ultrasonography and contrast-enhanced ultrasonography, which we used to evaluate IPN. RESULTS Diabetic complications were present in 41 of 50 patients (82 %) in the <60-year-old group, of whom 17 (34 %) had diabetes-related vascular complications. Of the 47 plaques in the <60-year-old group, six (13 %) had IPN Grade 0, 16 (34 %) had IPN Grade 1, and 25 (53 %) had IPN Grade 2. The AUC and RAUC of the plaque in the <60-year-old group were significantly higher than those of the ≥60-year-old group (P = 0.012 and 0.031, respectively). There were also differences in the AUC, RAUC and semi-quantitative grades between patients with and without diabetic macrovasculopathy and diabetic peripheral artery disease (all P < 0.05). The AUC, RAUC and semi-quantitative grading of IPN positively correlated with blood glucose and HbA1c (P < 0.05). CONCLUSION IPN is more common in DM patients who are younger, and have higher blood glucose and HbA1c concentrations, and these plaques are more vulnerable.

Safety of Triple Neuroprotection with Targeted Hypothermia, Controlled Induced Hypertension, and Barbiturate Infusion during Emergency Carotid Endarterectomy for Acute Stroke after Missing the 24 Hours Window Opportunity. Ann Vasc Surg 2020; 69:163-173. [PMID: 32473308 DOI: 10.1016/j.avsg.2020.05.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 04/30/2020] [Accepted: 05/02/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND The aim of this study is to establish the initial safety of triple neuroprotection (TNP) in an acute stroke setting in patients presenting outside the window for systemic tissue plasminogen activator (tPA). METHODS Over 12,000 patients were referred to our vascular services with carotid artery disease, of whom 832 had carotid intervention with a stroke rate of 0.72%. Of these, 25 patients presented (3%), between March 2015 and 2019, with acute dense stroke. These patients had either failed tPA or passed the recommended timing for acute stroke intervention. Fifteen (60%) had hemi-neglect with evidence of acute infarct on magnetic resonance imaging of the brain and a Rankin score of 4 or 5. Ninety-six percent had an 80-99% stenosis on the symptomatic side. Mean ABCD3-I score was 11.35. All patients underwent emergency carotid endarterectomy (CEA) with therapeutically induced hypothermia (32-34°C), targeted hypertension (systolic blood pressure 180-200 mm Hg), and brain suppression with barbiturate. RESULTS There were no cases of myocardial infarction, death, cranial nerve injury, wound hematoma, or procedural bleeding. Mean hospital stay was 8.4 (±9.5) days. All cases had resolution of neurological symptoms, except 3 who had failed previous thrombolysis. Eighty percent had a postoperative Rankin score of 0 on discharge and 88% of patients were discharged home with 3 requiring rehabilitation. CONCLUSIONS Positive neurological outcomes and no serious adverse events were observed using TNP during emergency CEA in patients with acute brain injury. We recommend TNP for patients who are at an increased risk of stroke perioperatively, or who have already suffered from an acute stroke beyond the recommended window of 24 hr. Certainly, the positive outcomes are not likely reproducible outside of high-volume units and patients requiring this surgery should be transferred to experienced surgeons in appropriate tertiary referral centers.

Effect of Prestroke Glycemic Variability Estimated Glycated Albumin on Stroke Severity and Infarct Volume in Diabetic Patients Presenting With Acute Ischemic Stroke. Front Endocrinol (Lausanne) 2020; 11:230. [PMID: 32373074 PMCID: PMC7186307 DOI: 10.3389/fendo.2020.00230] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Accepted: 03/30/2020] [Indexed: 12/15/2022] Open
Abstract
Background: We investigated whether prestroke glycemic variability, represented by glycated albumin (GA), affects the initial stroke severity and infarct volume in diabetic patients presenting with acute ischemic stroke. Methods: We evaluated a total of 296 acute ischemic stroke patients with diabetes mellitus who were hospitalized within 48 h of stroke onset. GA was measured in all acute ischemic stroke patients consecutively during the study period. The primary outcome was the initial National Institute Health Stroke Scale (NIHSS) score. The secondary outcome was infarct volume on diffusion-weighted imaging, which was performed within 24 h of stroke onset. Higher GA (≥16.0%) was determined to reflect glycemic fluctuation prior to ischemic stroke. Results: The number of patients with higher GA was 217 (73.3%). The prevalence of a severe initial NIHSS score (>14) was higher in patients with higher GA than in those with lower GA (3.8% vs. 15.7%, p = 0.01). The proportion of participants in the highest quartile of infarct volume was higher in the higher GA group (11.4% vs. 36.4%, p < 0.001). A multivariable analysis showed that higher GA was significantly associated with a severe NIHSS score (odds ratio, [95% confidence interval], 7.99 [1.75-36.45]) and large infarct volume (3.76 [1.05-13.45]). Conclusions: Prestroke glucose variability estimated by GA was associated with an increased risk of severe initial stroke severity and large infarct volume in acute ischemic stroke patients with diabetes mellitus.

Abstract
Background: Pre-morbid chronic hyperglycemia is associated with the poor outcome of ischemic stroke, but the association between chronic hyperglycemia, and the long-term outcome of acute intracerebral hemorrhage is still poor understood. Methods: Data on patients with acute intracerebral hemorrhage in the ACROSS-China registry (Abnormal Glucose Regulation in Patients With Acute Stroke Across China) were reviewed. Elevated hemoglobin A1c (HbA1c) level on admission was indicative of chronic hyperglycemia. According to the clinical categories of HbA1c, patients were divided into three groups. Multivariable logistic regression or Cox method was performed to analyze the association of HbA1c and the prognosis of patients with acute intracerebral hemorrhage (poor functional outcome [modified Rankin scale score 3–6] and mortality) at 1 year. Results: A total of 416 patients were included in this study. Fifty-two (12.5%) patients died and 130 (31.8%) had poor functional outcome at 1-year follow-up. The higher levels of HbA1c (≥6.5%) was associated with a poor functional outcome (OR 2.35, 95% CI, 1.28–4.29) and increased mortality (OR 2.63, 95% CI 1.34–5.15), compared with the lowest category. When further stratified by diabetic or non-diabetic medical history, higher HbA1c (≥6.5%) still increased the risk of poor functional outcome (OR 3.42, 95% CI 1.39–8.44) and mortality (OR 4.48, 95% CI 1.64–12.24) in patients with non-diabetic medical history. However, higher HbA1c didn't have the association with the increased risk of poor functional outcome (OR 1.06, 95% CI 0.37–3.03) and mortality (OR 1.20, 95% CI 0.39–3.72) in patients with diabetic medical history. Conclusions: Higher HbA1c was associated with a higher risk of death and poor functional outcome 1 year after intracerebral hemorrhage, especially in patients without a diabetic history.

Abstract
Fasting hyperglycemia is associated with poor neurologic outcome in acute ischemic stroke (AIS), but its relationship with in-hospital outcome in elderly patients remains largely unknown. To assess the association of in-hospital outcome with fasting plasma glucose (FPG) levels at admission in individuals with AIS.This retrospective propensity score-matched case-control study included patients aged over 60 years suffering from AIS and who were admitted to the emergency department from November 2013 to October 2016. Subjects were grouped into the poor-outcome and good-outcome groups based on mortality and intensive care unit (ICU) admission.The poor- and good-outcome groups comprised 74 and 1927 cases, respectively, before propensity score matching (PSM), and 74 and 296 cases, respectively, after PSM. Univariable logistic regression analysis showed that initial FPG after admission was associated with poor in-hospital outcome. Multivariable logistic regression analysis showed that initial FPG after admission was an independent predictor of poor in-hospital outcome (odds ratio = 1.11, 95% confidence interval: 1.037-1.188, P = .003).This study used PSM and strongly suggests that FPG is an independent predictive factor of poor in-hospital outcome in elderly patients with AIS. High initial FPG levels after admission may predict poor in-hospital outcome. Prospective studies are needed to confirm these findings.

Impact of obesity-induced type 2 diabetes on long-term outcomes following stroke. Clin Sci (Lond) 2019; 133:1603-1607. [PMID: 31331992 DOI: 10.1042/cs20190492] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 07/16/2019] [Accepted: 07/17/2019] [Indexed: 01/02/2023]
Abstract
Diabetes is associated with poor recovery profiles following stroke. The pathophysiological mechanisms by which diabetes mediates neurological recovery after stroke are debatable. A recent paper published in the Clinical Science by Pintana et al. (Clinical Science (2019)133, 1367-1386) provides a possible explanation for the underlying mechanisms of poor long-term motor recovery after stroke in obesity-induced diabetes animal model. Authors report that stroke-induced neurogenesis and parvalbumin (PV)+ interneuron-mediated neuroplasticity is severely impaired due to obesity-induced type 2 diabetes (T2D). Poor long-term motor recovery after stroke in comorbid obese and diabetic mice was not associated with stroke-induced grey or white matter damage. Understanding these mechanisms is crucial to develop therapeutic strategies to improve recovery in the obesity-induced diabetic population. The strength of the present study lies in the use of a comorbid obese/diabetic animal model, which is more likely to reflect the clinical scenario. However, these findings should be understood from the context of this specific animal model and whether these findings hold true for another variant of the obesity/T2D model warrants further consideration. This is an interesting study from the perspective of understanding the stroke pathology in T2D; however, the interaction of microvascular changes (including vascular modelling, angiogenesis), oxidative stress and insulin resistance (IR) associated with T2D and poor recovery profile merit further discussions. Given the increasing burden of obesity, diabetes and/or stroke globally, understanding of mechanisms may be useful in developing cardiovascular risk management pathways in this subgroup of population who are at increased risk of poor clinical outcomes following acute stroke.

Abstract
AIMS/INTRODUCTION Diabetes mellitus is an established risk factor for stroke and maybe associated with poorer outcomes after stroke. The aims of the present literature review were to determine: (i) the prevalence of diabetes in acute stroke patients through a meta-analysis; (ii) the association between diabetes and outcomes after ischemic and hemorrhagic stroke; and (iii) to review the value of glycated hemoglobin and admission glucose-based tests in predicting stroke outcomes. MATERIALS AND METHODS Ovid MEDLINE and EMBASE searches were carried out to find studies relating to diabetes and inpatient stroke populations published between January 2004 and April 2017. A meta-analysis of the prevalence of diabetes from included studies was undertaken. A narrative review on the associations of diabetes and different diagnostic methods on stroke outcomes was carried out. RESULTS A total of 66 eligible articles met inclusion criteria. A meta-analysis of 39 studies (n = 359,783) estimated the prevalence of diabetes to be 28% (95% confidence interval 26-31). The rate was higher in ischemic (33%, 95% confidence interval 28-38) compared with hemorrhagic stroke (26%, 95% confidence interval 19-33) inpatients. Most, but not all, studies found that acute hyperglycemia and diabetes were associated with poorer outcomes after ischemic or hemorrhagic strokes: including higher mortality, poorer neurological and functional outcomes, longer hospital stay, higher readmission rates, and stroke recurrence. Diagnostic methods for establishing diagnosis were heterogeneous between the reviewed studies. CONCLUSIONS Approximately one-third of all stroke patients have diabetes. Uniform methods to screen for diabetes after stroke are required to identify individuals with diabetes to design interventions aimed at reducing poor outcomes in this high-risk population.

Abstract
AIMS Diabetes is a major risk factor for stroke. We aimed to investigate the prevalence of diabetes and pre-diabetes within a stroke cohort and examine the association of glycaemia status with mortality and morbidity. METHODS Inpatients aged ≥54 who presented with a diagnosis of stroke had a routine HbA1c measurement as part of the Austin Health Diabetes Discovery Initiative. Additional data were attained from hospital databases and Australian Stroke Clinical Registry. Outcomes included diabetes and pre-diabetes prevalence, length of stay, 6-month and in-hospital mortality, 28-day readmission rates, and 3-month modified Rankin scale score. RESULTS Between July 2013 and December 2015, 610 patients were studied. Of these, 31% had diabetes while 40% had pre-diabetes. Using multivariable regression analyses, the presence of diabetes was associated with higher odds of 6-month mortality (OR = 1.90, p = 0.022) and higher expected length of stay (IRR = 1.29, p = 0.004). Similarly, a higher HbA1c was associated with higher odds of 6-month mortality (OR = 1.27, p = 0.005) and higher expected length of stay (IRR = 1.08, p = 0.010). CONCLUSIONS 71% of this cohort had diabetes or pre-diabetes. Presence of diabetes and higher HbA1c were associated with higher 6-month mortality and length of stay. Further research is necessary to determine if improved glycaemic control may improve stroke outcomes.

Abstract
OBJECTIVES To determine whether chronic hyperglycaemia predisposes patients to dehydration, which may promote neurological deterioration, and to investigate whether dehydration control improves functional outcome. PATIENTS AND METHODS This study included 355 patients hospitalized with acute ischaemic stroke and diabetes mellitus who fulfilled the glycaemic gap ≤0. We used the following cut-offs: (i) no chronic hyperglycaemia (glycated haemoglobin A1c [HbA1c] < 7%) and (ii) chronic hyperglycaemia (HbA1c ≥ 7%). The chronic hyperglycaemic patients were randomly divided into the control group and the hydration group. Hydration therapy was only initiated in the hydration group. The blood urea nitrogen (BUN)/creatinine (Cr) ratio was used as an indicator of dehydration. Stroke severity on admission and discharge was assessed by means of National Institutes of Health Stroke Scale (NIHSS). RESULTS The mean baseline BUN/Cr ratios were higher in the control group and hydration group than in the no chronic hyperglycaemia group. The mean BUN/Cr ratio decreased from 91.22 ± 29.95 on the first day to 77.03 ± 18.23 on the third day (P < .001) in the hydration group. On the third day after admission, there was no significant difference in the BUN/Cr ratio between the hydration group and the no chronic hyperglycaemia group (P = .831). Moreover, neurological deterioration was highest in the control group (33.6%, 36/107), followed by the hydration group (10.5%, 11/105) and the no chronic hyperglycaemia group (5.6%, 8/143). CONCLUSIONS Chronic hyperglycaemia was associated with the admission NIHSS score and neurological deterioration after excluding the effect of stress hyperglycaemia. Furthermore, hydration therapy may help prevent neurological deterioration.

Abstract
Background The association between 2-h postprandial blood glucose level (2hPBG) and functional outcomes in patients with small-artery occlusion (SAO) is poorly understood. We aimed to explore the relationship between 2hPBG levels and functional outcomes in SAO patients with diabetes. Methods We retrospectively analyzed 174 diabetic patients diagnosed with SAO, and 2hPBG values were classified into four groups according to quartiles (<8.90, 8.90 to <12.16, 12.16 to <15.14, and ≥15.14 mmol/L), or according to clinical glycemic recommendations for adults with diabetes (<10 and ≥10 mmol/L, respectively). The relationship between 2hPBG levels and modified Rankin Scale (mRS) scores was assessed using univariate and multivariate analyses. Results Among all patients with SAO, there were 139 patients with favorable outcomes and 35 patients with poor outcomes. National Institutes of Health Stroke Scale scores were significantly different according to mRS scores (P < 0.001) in both the univariate and multivariate analyses. The binary logistic regression analyses showed that compared with the lowest quartile (<8.90 mmol/L), elevated 2hPBG levels (8.90 to <12.16, 12.16 to <15.14, and ≥15.14 mmol/L) were not associated with mRS scores after adjusting for multiple confounding factors. Compared with patients with 2hPBG levels <10 mmol/L, those with 2hPBG levels ≥10 mmol/L did not have a significant risk of poor outcome after adjusting for confounders. Meanwhile, the negative results appeared in the ordinal logistic regression of 2hPBG levels and 3-month functional outcomes. Conclusion Elevated 2hPBG levels were not associated with unfavorable functional outcomes 3 months after stroke onset in SAO patients with diabetes.

Abstract
BACKGROUND AND OBJECTIVE Stress hyperglycemia has been associated with a worse prognosis in patients hospitalized in critical care units. The aim of this study is to evaluate the impact of blood glucose and glycosylated hemoglobin (HbA1c) levels on the mortality of patients suffering a acute cerebro-vascular event, and to determine if this relationship depends on the presence of diabetes. MATERIAL AND METHODS A retrospective analysis of 255 patients admitted to the ER for stroke was performed. Venous plasma glucose levels in the emergency room and HbA1c levels within the first 48hours were analyzed. The presence of diabetes was defined in terms of the patients' medical history, as well as their levels of fasting plasma glucose and HbA1c. Mortality was assessed within the first 30 months after the onset of the acute event. RESULTS 28.2% of patients had diabetes. Higher mortality was observed in patients who had been admitted with plasma glucose levels≥140mg/dl (hazard ratio [HR]=2.22, 95% CI: 1.18-4.16, P=.013) after adjusting for various factors. This relationship was not confirmed in diabetic patients (HR=2.20, 95% CI: 0.66-7.40, P=.201) and was in non-diabetics (HR=2.55, 95% CI: 1.11-5.85, P=.027). In diabetics, HbA1c≥7% was not associated with poor prognosis (HR=0.68, 95% CI: 0.23-1.98, P=.475), whereas non-diabetics with admission levels of HbA1c falling within the pre-diabetes range (5.7% -6.4%) had a higher mortality (HR=2.62, 95% CI: 1.01-6.79, P=.048). CONCLUSION Admission hyperglycemia is associated with a worse prognosis in patients without diabetes admitted for stroke, but this relationship was not seen in diabetics. In non-diabetic patients, HbA1c levels in the pre-diabetes range is associated with higher mortality.

Comparison of admission random glucose, fasting glucose, and glycated hemoglobin in predicting the neurological outcome of acute ischemic stroke: a retrospective study. PeerJ 2017; 5:e2948. [PMID: 28168113 PMCID: PMC5292024 DOI: 10.7717/peerj.2948] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Accepted: 12/30/2016] [Indexed: 12/15/2022] Open
Abstract
Background Hyperglycemia is a known predictor of negative outcomes in stroke. Several glycemic measures, including admission random glucose, fasting glucose, and glycated hemoglobin (HbA1c), have been associated with bad neurological outcomes in acute ischemic stroke, particularly in nondiabetic patients. However, the predictive power of these glycemic measures is yet to be investigated. Methods This retrospective study enrolled 484 patients with acute ischemic stroke from January 2009 to March 2013, and complete records of initial stroke severity, neurological outcomes at three months, and glycemic measures were evaluated. We examined the predictive power of admission random glucose, fasting glucose, and HbA1c for neurological outcomes in acute ischemic stroke. Furthermore, subgroup analyses of nondiabetic patients and patients with diabetes were performed separately. Results Receiver operating characteristic (ROC) analysis revealed that admission random glucose and fasting glucose were significant predictors of poor neurological outcomes, whereas HbA1c was not (areas under the ROC curve (AUCs): admission random glucose = 0.564, p = 0.026; fasting glucose = 0.598, p = 0.001; HbA1c = 0.510, p = 0.742). Subgroup analyses of nondiabetic patients and those with diabetes revealed that only fasting glucose predicts neurological outcomes in patients with diabetes, and the AUCs of these three glycemic measures did not differ between the two groups. A multivariate logistic regression analysis of the study patients indicated that only age, initial stroke severity, and fasting glucose were independent predictors of poor neurological outcomes, whereas admission random glucose and HbA1c were not (adjusted odds ratio: admission random glucose = 1.002, p = 0.228; fasting glucose = 1.005, p = 0.039; HbA1c = 1.160, p = 0.076). Furthermore, subgroup multivariate logistic regression analyses of nondiabetic patients and those with diabetes indicated that none of the three glycemic measures were associated with poor neurological outcomes. Discussion Fasting glucose is an independent predictor of poor neurological outcomes in patients with acute ischemic stroke and had greater predictive power than that of admission random glucose and HbA1c. The predictive power of glycemic measures for poor neurological outcomes did not differ significantly between the nondiabetic patients and those with diabetes.

Abstract
Background Acute hyperglycemia is associated with poor functional outcome after ischemic stroke, but the association between chronic antecedent hyperglycemia and outcome is unclear. Aim We assessed the association between chronic hyperglycemia, measured by hemoglobin A1c, and functional outcome in patients with acute ischemic stroke. Methods We included 812 patients with acute ischemic stroke (mean age 66 ± 14 years; 61.5% male). Patients were categorized per hemoglobin A1c level: no (<39 mmol/mol), moderate (39-42 mmol/mol), or severe chronic hyperglycemia (>42 mmol/mol). Poor functional outcome was defined as modified Rankin Scale score > 2 after 3 months. The relation between chronic hyperglycemia and functional outcome was assessed with a Poisson regression analysis and expressed as risk ratios with 95% confidence intervals with no chronic hyperglycemia as the reference. Results Moderate chronic hyperglycemia was present in 234 (28.8%) patients and severe chronic hyperglycemia in 183 (22.5%) patients. Acute hyperglycemia on admission was present in 338 (41.6%) patients. Severe chronic hyperglycemia was associated with poor outcome (risk ratios 1.40; 95% confidence interval 1.09-1.79). After adjustment for age, sex, stroke severity, vascular risk factors, and acute hyperglycemia on admission the risk ratios was 1.35 (95% confidence interval 1.04-1.76). Moderate chronic hyperglycemia was not associated with poor outcome (risk ratios 1.12; 95% confidence interval 0.87-1.44). Conclusion Severe chronic hyperglycemia is associated with poor functional outcome in patients with acute ischemic stroke. This association is independent of hyperglycemia in the acute stage of stroke and of an unfavorable vascular risk factor profile.

Elevated hemoglobin A1c Is Associated with Carotid Plaque Vulnerability: Novel Findings from Magnetic Resonance Imaging Study in Hypertensive Stroke Patients. Sci Rep 2016; 6:33246.

Abstract
The association between hemoglobin A1c (HbA1c) level and carotid plaque vulnerability has been rarely studied by magnetic resonance imaging (MRI). The present study of MRI-identified carotid atherosclerotic lesions in hypertensive patients with acute stroke therefore sought to determine the associations between HbA1c level and plaque morphological and compositional characteristics and acute cerebral infarction (ACI) severity. Eighty hypertensive patients with acute stroke were enrolled; stratified into high (≥6.5%) and low (<6.5%) HbA1c groups; and underwent carotid and brain MRI to assess carotid plaque features and ACI volume in the region supplied by the internal carotid artery (ICA) in the symptomatic side. Plaque burden [percent wall volume (PWV), max wall thickness (max-WT)] and lipid-rich necrotic core (LRNC) were larger in the high as compared to the low HbA1c group. High HbA1c was an independent risk factor for the presence of plaque (odds ratio [OR] = 3.71) and LRNC plaque (OR = 7.08). HbA1c independently correlated with ACI severity among patients with ICA region cerebral infarction and carotid plaque. Our study suggested that an elevated HbA1c may have an adverse effect on carotid plaque vulnerability especially those with larger LRNC volumes in hypertensive stroke patients, which might exacerbate the severity of ACIs.

Abstract
Introduction Abnormal glucose metabolism is an independent risk factor for poor outcome following acute ischemic stroke. However, the relationship between initial hemoglobin A1c level and functional outcome (defined by modified Rankin Scale scores) following small-artery occlusion, a subtype of ischemic stroke, is unknown. The aim of the present study was to evaluate this association among patients diagnosed with small-artery occlusion. Materials and Methods Data on 793 patients diagnosed with small-artery occlusion from October 25, 2012 to June 30, 2015 were collected from the stroke registry of the Department of Neurorehabilitation of HuanHu Hospital. Hemoglobin A1c values at admission were classified into three groups according to tertiles (<5.9,5.9to<6.7, and≥6.7). We used receiver operating characteristics curves to investigate the predictive value of hemoglobin A1c and examined the relationship between hemoglobin A1c levels at admission and modified Rankin Scale scores using univariate and multivariate analyses. Results The area under the curve was 0.570 (95%CI, 0.509–0.631; P = 0.023). Patients in the highest HbA1c stratification (≥6.7) had a significantly higher risk of an unfavorable outcome than patients in the lowest stratification (<5.9; adjusted odds ratio, 2.099; 95%CI, 1.160–3.798; P = 0.014). However, a significant association was not seen in the middle stratification (5.9 to <6.7; P = 0.115). Conclusions Elevated hemoglobin A1c level on admission was adversely associated with functional outcomes 3 months after stroke onset among patients presenting with small-artery occlusion.

Abstract
Objective To elucidate the association between glycemic control status and clinical outcomes in patients with acute ischemic stroke limited to the deep branch of the middle cerebral artery (MCA). Methods We evaluated 65 subjects with first-ever ischemic stroke of the deep branches of the MCA, which was confirmed by magnetic resonance angiography. All subjects had blood hemoglobin A1c (HbA1c) measured at admission. They were classified into two groups according to the level of HbA1c (low <7.0% or high ≥7.0%). Neurological impairment and functional status were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Functional Independence Measure (FIM), Korean version of Modified Barthel Index (K-MBI), Korean version of Mini-Mental State Examination (MMSE-K), and the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) at admission and discharge. Body mass index, serum glucose, homocysteine and cholesterol levels were also measured at admission. Results The two groups did not show any difference in the NIHSS, FIM, K-MBI, MMSE-K, and LOTCA scores at any time point. Body mass index and levels of blood homocysteine and cholesterol were not different between the two groups. The serum blood glucose level at admission was negatively correlated with all outcome measures. Conclusion We found that HbA1c cannot be used for predication of clinical outcome in patients with ischemic stroke of the deep branch of the middle cerebral artery.

Abstract
OBJECTIVES To identify the effect of internal carotid artery (ICA) stenosis, blood pressure (BP), glycated hemoglobin (HbA1c), and hemoglobin level on blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) signals in stroke patients. METHODS A total of 18 stroke patients with acute cerebral infarction (13 males and 5 females) and 13 age-matched healthy controls (5 males and 8 females) were recruited. Among 18 stroke patients, 8 had significant ICA stenosis (> 50%) and 10 had nonsignificant ICA stenosis (< 50%). During handgrip task, stroke patients and normal controls were allowed to use their hands coincided with infarction and right hands, respectively. RESULTS The mean BOLD signals in patients with significant ICA stenosis were significantly less than that in patients with nonsignificant ICA stenosis. Mean arterial pressure (MAP) was significantly correlated with activated voxels of Brodmann area 4 (P < 0.01) and total activated voxels (P = 0.007), whereas hemoglobin and HbA1c showed no significant correlation with activated voxels of Brodmann area 4 or total activated voxels (P > 0.05). CONCLUSION It is suggested that both ICA stenosis and arterial BP could influence BOLD signal, while HbA1c and hemoglobin level had no effect on BOLD signal.

The role of prestroke glycemic control on severity and outcome of acute ischemic stroke. Stroke Res Treat 2014; 2014:694569.

Abstract
Background/Aim. Relatively few studies have investigated the association of prestroke glycemic control and clinical outcome in acute ischemic stroke (IS) patients, regardless of presence of diabetes mellitus (DM). The aim of this study was to investigate the importance of prestroke glycemic control on survival, stroke severity, and functional outcome of patients with acute IS. Methods. We performed a retrospective survival analysis of 501 patients with IS admitted to Sahlgrenska University Hospital from February 15, 2005, through May 31, 2009. The outcomes of interest were acute and long-term survival; the stroke severity (NIHSS) and the functional outcome, mRS, at 12 months. Results. HbA1c was a good predictor of acute (HR 1.45; CI, 1.09 to 1.93, P = 0.011) and long-term mortality (HR 1.29; CI 1.03 to 1.62; P = 0.029). Furthermore, HbA1c >6% was significantly correlated with acute stroke severity (OR 1.29; CI 1.01 to 1.67; P = 0.042) and predicted worse functional outcome at 12 months (OR 2.68; CI 1.14 to 6.03; P = 0.024). Conclusions. Our study suggests that poor glycemic control (baseline HbA1c) prior to IS is an independent risk factor for poor survival and a marker for increased stroke severity and unfavorable long-term functional outcome.
