Background. Diabetes mellitus (DM) aggravates symptoms and prognosis of acute ischemic stroke (AIS), and inflammation plays an important role therein. Resolvin D2 (RvD2) is one of the specialized pro-resolving mediators (SPMs), while leukotriene B4 (LTB4) is a classic proinflammatory mediator. The ratio of RvD2 to LTB4 is an index of pro-resolving/proinflammatory balance. We aim to explore the role of RvD2/LTB4 ratio in ischemic stroke complicated with DM. Methods. The plasma levels of RvD2 and LTB4 were analyzed by enzyme immunoassay in stroke patients with DM (DM + AIS group) or without DM (nonDM+AIS group). Patients were followed up at 90 days after stroke onset, and modified Rankin Score (mRS) was assessed. The association of RvD2/LTB4 ratio with stroke severity and prognosis was also analyzed. Results. The plasma levels of RvD2 were positively correlated to LTB4. The RvD2/LTB4 ratio in DM + AIS group was lower than that in the nonDM+AIS group. No correlation was found between the RvD2/LTB4 ratio and infarct size or NIHSS score. The RvD2/LTB4 ratio at baseline was significantly lower in the poor prognosis group ( mRS ≥ 3 ) than that in the good prognosis group ( mRS ≤ 2 ). Conclusions. Our study indicated that the balance between pro-resolving and proinflammatory mediators was impaired by diabetes in ischemic stroke. The RvD2/LTB4 ratio may serve as a biomarker of prognosis for ischemic stroke.

Background Traumatic brain injury (TBI) seriously affects the quality of life of patients. The present study evaluated the role of diffusion tensor imaging (DTI) combined with Neuron-Specific Enolase (NSE) and S100 calcium-binding protein B (S100B) protein in predicting the prognosis of moderate and severe TBI. Methods The TBI patients were divided into moderate TBI (TBIm) and severe TBI (TBIs) groups according to the Glasgow Coma Scale (GCS) after admission. The patients were then divided into good and poor prognosis groups according to the Glasgow Outcome Scale (GOS); moreover, their follow-ups were recorded at 3 and 6 months after injury. This study also included 65 healthy individuals with matched age and gender as the control group. The fractional anisotropy (FA) values of DTI, serum neuron-specific enolase (NSE), and S100B protein levels were detected in this study. The data were analyzed in SPSS software (version 22.0) to evaluate the role of DTI combined with NSE and S100B protein in predicting the prognosis in TBIm and TBIs. Results: After TBI, the FA values of DTI in the TBI group were lower than those in the control group (P<0.05); moreover, the serum NSE and S100B values in the TBI group were higher than those in the control group (P<0.05). In the TBIm patients, the FA values of the corpus callosum in the good prognosis group were higher than that in the poor prognosis group (P<0.05); however, there was no significant difference between the two groups regarding the FA values of the internal capsule and the cerebral peduncle (P>0.05). The serum levels of NSE and S100B in the good prognosis group were significantly lower than those in the poor prognosis group (P<0.05). In the TBIs patients, the FA value of all areas in the good prognosis group was significantly higher than that in the poor prognosis group (P<0.05). However, there was no significant difference between the two prognosis groups regarding the serum levels of NSE and S100B (P>0.05). Conclusion Although DTI combined with NSE and S100B protein can effectively predict the prognosis of patients with moderate and severe TBI in the early stages, various other measures have been used in the studies to predict the prognosis of TBI patients. Accordingly, comparison with other measures is essential in further studies.

<b><i>Introduction:</i></b> Genetic variants could aid in predicting antidiabetic drug response by associating them with markers of glucose control, such as glycated hemoglobin (HbA1c). However, pharmacogenetic implementation for antidiabetics is still under development, as the list of actionable markers is being populated and validated. This study explores potential associations between genetic variants and plasma levels of HbA1c in 100 patients under treatment with metformin. <b><i>Methods:</i></b> HbA1c was measured in a clinical chemistry analyzer (Roche), genotyping was performed in an Illumina-GSA array and data were analyzed using PLINK. Association and prediction models were developed using R and a 10-fold cross-validation approach. <b><i>Results:</i></b> We identified genetic variants on <i>SLC47A1, SLC28A1, ABCG2, TBC1D4,</i> and <i>ARID5B</i> that can explain up to 55% of the interindividual variability of HbA1c plasma levels in diabetic patients under treatment. Variants on <i>SLC47A1</i>, <i>SLC28A1</i>, and <i>ABCG2</i> likely impact the pharmacokinetics (PK) of metformin, while the role of the two latter can be related to insulin resistance and regulation of adipogenesis. <b><i>Conclusions:</i></b> Our results confirm previous genetic associations and point to previously unassociated gene variants for metformin PK and glucose control.

Abstract Background Several factors affect acute ischemic stroke (AIS) outcomes. Objective This study aimed to assess the role of the leukocyte count, neutrophil/lymphocyte ratio (NLR), and c reactive protein (CRP) as early predictors of outcome in AIS patients. Methods This study was conducted on 60 AIS patients. They were subjected to detailed history taking, clinical examination, brain imaging, and laboratory assessment including the CRP, white blood cell (WBC) count, absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and NLR which is calculated by dividing ANC by ALC. Neurological scales were used to assess the level of consciousness by the Glasgow Coma Scale (GCS) and stroke severity by the National Institute of Health Stroke Scale (NIHSS) at the first 48 h of stroke onset as well as 1 week and 2 weeks later for the assessment of short-term functional neurological outcome. Results Sixty percent of the patients had unfavorable outcomes assessed by the Modified Rankin Scale (mRS). Patients with unfavorable outcomes had higher NIHSS scores. NLR was positively correlated with WBC count, ANC, and CRP. The higher WBC, NLR, and NIHSS, the unfavorable the outcome was. Conclusion The higher WBC, the NLR, and the level of CRP at the onset of AIS, the more severe stroke and the poorer the short-term outcome are expected.

Objective: To explore the correlation of procalcitonin (PCT) and gelsolin (GSN) with the prognosis of urosepsis patients. Method: The data of 71 urosepsis patients from March 2015 to April 2019 who were admitted to and treated in Affiliated Hospital of Hebei University were analyzed and compared with those of 92 healthy persons. Serum PCT and plasma GSN levels at different times after treatment were detected. According to prognosis, patients were classified into the good prognosis group or the poor prognosis group. The serum PCT and plasma GSN levels of both groups were compared. Result: The serum PCT level of the urosepsis group on the 1st, 3rd, 5th and 7th days was obviously higher than that of the control group (P<0.05). The plasma GSN levels of the urosepsis group on the 1st, 3rd, 5th and 7th days were obviously lower than those of the control group (P<0.05).The serum PCT level of the poor prognosis group on the 1st, 3rd, 5th and 7th days was obviously higher than that of the good prognosis group (P<0.05). The plasma GSN level of the poor prognosis group on the 1st, 3rd, 5th and 7th days was obviously lower than that of the good prognosis group (P<0.05). PCT was an independent risk factor influencing the prognosis of urosepsis patients and that GSN was a protective factor (P<0.05). Conclusion: The serum PCT and plasma GSN levels can accurately predict the severity and prognosis of urosepsis patients and reflect the disease state of early urosepsis patients. High PCT levels and low GSN levels indicate poor prognosis, and clinicians should consider these values. doi: https://doi.org/10.12669/pjms.36.5.2143 How to cite this:Cui N, Yu Z, Chen Z, Chen N.

Abstract Background: Intravenous thrombolysis (IVT) is a rapid and effective treatment in the early stage of ischemic stroke patients and the purpose of this work is to explore the significance of Hounsfield unit(HU) value in Alberta Stroke Program Early CT Score (ASPECTS) for predicting the clinical prognosis of stroke patients with middle cerebral artery occlusion (MCAO) treated by IVT. Methods: The 84 stroke patients with MCAO treated by IVT were divided into good prognosis group (48 cases) and poor prognosis group (36 cases). HU ratio and HU difference calculated from non-contrast computed tomography (NCCT) between groups were analyzed. Results: The HU ratio of good prognosis group was higher than that in poor prognosis group and the HU difference of good prognosis group was lower than that in poor prognosis group (P<0.05). The HU ratio was negatively correlated with the infarct volume, and the HU difference was positively correlated with the infarct volume (P<0.05). HU difference was an independent risk factor for prognosis of patients with MCAO treated by IVT. The area under the curve (AUC) of HU ratio and HU difference for prognosis was 0.743 and 0.833 respectively (P<0.05). Conclusion: The HU value changes are related to the clinical prognosis of stroke patients with MCAO treated by IVT, HU value may be a prognostic indicator for stroke patients with MCAO treated by IVT.

Abstract Background The role of oxidative stress in neuronal injury due to ischemic stroke has been an interesting topic in stroke research. Malondialdehyde (MDA) has emerged as a sensitive oxidative stress biomarker owing to its ability to react with the lipid membranes. Total antioxidant power (TAP) is another biomarker to estimate the total oxidative stress in stroke patients. We aimed to determine the oxidative stress in acute stroke patients by measuring MDA and TAP. Materials and Methods MDA and TAP were determined in 100 patients with ischemic stroke and compared with that in 100 age- and sex-matched healthy adults. Demographic data, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), and disability measured by the Barthel index (BI) were recorded. The association of MDA and TAP with other variables was analyzed by paired t-test. Results Of the whole sample, 74% represented males. The mean NIHSS score was 13.11 and BI was 38.87. MDA was significantly higher in stroke patients (7.11 ± 1.67) than in controls (1.64 ± 0.82; p = 0.00). TAP was significantly lower in stroke patients (5.72 ± 1.41) than in controls (8.53 ± 2.4; p = 0.00). The lipid profile and blood sugar levels were also significantly higher in stroke patients. There was no association of MDA and TAP with other variables. Conclusion We found that oxidative stress was associated with acute ischemic stroke. However, we could not establish an association between oxidative stress and the severity of acute stroke.

Type 2 diabetes (T2D) is a growing pandemic associated with metabolic dysregulation and chronic inflammation. Meteorin-like hormone (METRNL) is an adipomyokine that is linked to T2D. Our objective was to evaluate the changes in METRNL levels in T2D and obesity and assess the association of METRNL levels with irisin. Overall, 228 Arab individuals were enrolled. Plasma levels of METRNL and irisin were assessed using immunoassay. Plasma levels of METRNL and irisin were significantly higher in T2D patients than in non-diabetic patients (p < 0.05). When the population was stratified based on obesity, METRNL and irisin levels were significantly higher in obese than in non-obese individuals (p < 0.05). We found a significant positive correlation between METRNL and irisin (r = 0.233 and p = 0.001). Additionally, METRNL and irisin showed significant correlation with various metabolic biomarkers associated with T2D and Obesity. Our data shows elevated METRNL plasma levels in individuals with T2D, further exacerbated with obesity. Additionally, a strong positive association was observed between METRNL and irisin. Further studies are necessary to examine the role of these proteins in T2D and obesity, against their ethnic background and to understand the mechanistic significance of their possible interplay.

Background and Purpose: Little attention has been paid to the pathogenesis of in-hospital stroke, despite poor outcomes and a longer time from stroke onset to treatment. We studied the pathophysiology and biomarkers for detecting patients who progress to in-hospital ischemic stroke (IHS). Methods: Seventy-nine patients with IHS were sequentially recruited in the period 2011–2017. Their characteristics, care, and outcomes were compared with 933 patients who had an out-of-hospital ischemic stroke (OHS) using a prospectively collected database of the Tokushima University Stroke Registry. Results: Active cancer and coronary artery disease were more prevalent in patients with IHS than in those with OHS (53.2 and 27.8% vs. 2.0 and 10.9%, respectively; p < 0.001), the median onset-to-evaluation time was longer (300 vs. 240 min; p = 0.015), and the undetermined etiology was significantly higher (36.7 vs. 2.4%; p < 0.001). Although there was no significant difference in stroke severity at onset between the groups, patients with IHS had higher modified Rankin Scale (mRS) scores (3–6) at discharge (67.1 vs. 50.3%; p = 0.004) and rates of death during hospitalization (16.5 vs. 2.9%; p < 0.001). D-dimer (5.8 vs. 0.8 µg/mL; p < 0.001) and fibrinogen (532 vs. 430 mg/dL; p = 0.014) plasma levels at the time of onset were significantly higher in patients with IHS after propensity score matching. Multivariate logistic regression analysis revealed that active cancer (odds ratio [OR] 2.30; 95% confidence interval [CI] 1.26–4.20), prestroke mRS scores 3–5 (OR 6.78; 95% CI 3.96–11.61), female sex (OR 1.57; 95% CI 1.19–2.08), and age ≥75 years (OR 2.36; 95% CI 1.80–3.08) were associated with poor outcomes. Conclusions: Patients with IHS had poorer outcomes than those with OHS because of a higher prevalence of active cancer and functional dependence before stroke onset. Elevated plasma levels of D-dimer and fibrinogen, especially with active cancer, can help identify patients who are at a higher risk of progression to IHS.
