In the multivariable model, compared with the lowest tertile of left atrial size, the odds ratio for moderate-to-severe neurologic deficit was 0.902 (95% CI, 0.644-1.264, P = .550) when left atrial size was the highest tertile. Of all patients, 190 patients were further categorized as cardioembolic and cryptogenic subtypes, and 70 (36.8%) were classified into moderate-to-severe stroke severity. After adjusting for confounders, compared with the lowest tertile, the top tertile of left atrial size was significantly associated with moderate-to-severe stroke (3.156, 95% CI, 1.143-8.711, P = .027). CONCLUSION Left atrial enlargement was associated with more severe initial neurologic deficits of embolic subtypes (cardioembolic and cryptogenic stroke) in patients with acute ischemic stroke. BACKGROUND Stroke education in adolescents has been established as an effective method of creating awareness about stroke, its warning signs and risk factors. It contributes to desired behavioural change in the adolescents as well as their parents. Thus, we aimed to determine the baseline knowledge of school attending adolescents about stroke and its risk factors as well as the effect of stroke education on their stroke awareness. METHODS This study employed a quasi-experimental study design and was conducted in secondary schools in Ile-Ife, Osun State, Nigeria. The schools were divided into intervention and control groups. We assessed the baseline knowledge of the students on stroke, its risk factors, warning signs, and ways of preventing it using a pre-tested structured questionnaire in both intervention and control groups. In the intervention group, health talks on stroke consisting of oral presentation and distribution of fliers were presented for 30 minutes in each selected school. Each school was visited 2 weeks after the health education intervention to assess their knowledge on stroke, its risk factors, and ways of preventing it. The control group was also visited after 2 weeks for a re-assessment of their stroke knowledge and the conduct of heath talk on other aspects of neurology such as sleep, epilepsy, etc. Results A total of 1259 adolescents were studied with 661 in the intervention group and 598 in the control group. The mean age of the respondents was 13.56 ± 2.87 the intervention group and 13.38 ± 2.06 in the control group. There were higher mean scores on knowledge of stroke and its risk factors among the intervention group than seen in the control group after the stroke education. CONCLUSIONS Stroke education is an effective way of creating and maintaining stroke awareness among school-attending adolescents. OBJECTIVE The pathophysiology of delayed cerebral ischemia (DCI) following aneurysmal subarachnoid hemorrhage (aSAH) has not been fully evaluated. The aim of this study was to evaluate the dynamics of lactate and lactate dehydrogenase (LDH) in carotid cisternal cerebrospinal fluid (CSF), and to discuss their effectiveness as markers of early brain injury (EBI) and DCI following aSAH. PATIENTS AND METHODS Among 91 consecutive aSAH patients treated between January 2012 and March 2019 at National Hospital Organization Beppu Medical Center, 19 patients (20.9%) were eligible for this retrospective study. Concentrations of lactate and LDH in carotid cisternal CSF within 14 days after onset of aSAH were evaluated. RESULTS Six of the 19 patients (31.6%) had a history of DCI. Both lactate and LDH levels in carotid cisternal CSF were significantly higher in the DCI group than in the non-DCI group on postbleeding day (PBD) 1-2, 3-4, and 5-6. Interestingly, neither lactate nor LDH levels in blood differed significantly between DCI and non-DCI groups on PBD 1-2. CONCLUSIONS Lactate and LDH concentrations in carotid cisternal CSF may vividly reflect the EBI and may thus represent predictive biomarkers of DCI following aSAH. OBJECTIVE To investigate the association of early serum calprotectin (S100A8/A9) level with disease severity and prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). PATIENTS AND METHODS Serum samples were collected from 54 patients with aSAH (within 48 hours of onset) and 54 health controls. Levels of serum calprotectin were determined by enzyme linked immunosorbent assay. The clinical data of aSAH patients were collected. The prognosis was evaluated by modified Rankin scale at 3 months. Univariate and multivariable logistic regression analysis, bivariate correlation analysis and receiver operating characteristic (ROC) curve analysis were used respectively. RESULTS Serum calprotectin levels were significantly higher in aSAH patients than that in healthy controls (P less then .001). The clinical severity was also significantly correlated with the level of serum calprotectin. Patients with poor prognosis at 3 months showed higher serum calprotectin levels within 48 hours of onset than that in patients with good prognosis (P = .002). The level of serum calprotectin within 48 hours was related to the complications of secondary pneumonia. Serum calprotectin can be used as an independent predictor for delayed cerebral ischemia (DCI) after aSAH and poor prognosis in patients with aSAH at 3 months. The ROC curve showed the cutoff value of calprotectin for predicting poor prognosis at 3 months was 6020 pg/ml (sensitivity 53.57%, specificity 96.15%), and the cutoff value for predicting DCI was 5275 pg/ml (sensitivity 68.42%, specificity 82.86%). CONCLUSION Serum calprotectin concentrations within 48 hours after onset was significantly correlated with the clinical severity and the poor prognosis at 3 months in aSAH patients, suggesting that serum calprotectin may be a biomarker for early prediction of prognosis and complications in patients with aSAH and calprotectin may be a target for the treatment of aSAH. BACKGROUND Recombinant tissue plasminogen activator (rt-PA, alteplase) within 4.5 hours of symptom onset decreases the rate of disability after acute ischemic stroke (AIS). Due to various reasons, alteplase remains underutilized in certain regions (∼3% in low- and middle-income countries). AIMS We aimed to estimate the alteplase utilization rate and identify the reasons for nonuse in Saudi Arabia. METHODS We retrospectively reviewed all patients admitted with suspected stroke in the past 24 hours to the stroke unit at King Abdulaziz Medical City, Riyadh, Saudi Arabia from February 2016 to July 2018. We estimated the alteplase utilization rate among patients with AIS who could be treated within 4.5 hours of symptoms onset (≤225 minutes, allowing 45 minutes for door to needle time). We examined potential predictors of alteplase use using multivariable logistic regression analyses. Study was approved by local IRB. RESULTS Of 1366 patients with suspected stroke, 819 (60%) had AIS. The alteplase utilization rates were 8.6% and 29% for all AIS and AIS arrived within the therapeutic window, respectively. The most common reason for no alteplase treatment was late arrival. Only 244 (29.8%) of AIS patients arrived within the time window for treatment. Among patients with sudden neurological deficit who arrived within the therapeutic time window, the most common reasons were mild neurological deficit (National Institutes of Health Stroke Scale score less then 5, 29.9%), stroke mimics (16.6%), and hemorrhagic stroke (8.1%). CONCLUSIONS Our study showed a comparable alteplase utilization rate with most international estimates. Transmembrane Transporters inhibitor The low utilization rate was mainly attributed to late patient arrival. Urgent interventions are needed to improve public awareness of stroke recognition and prehospital stroke care. BACKGROUND An adequate stroke literacy among the general public and first-contact physicians is an essential prerequisite to ensure timely treatment and prevention of stroke. Knowledge on stroke pathophysiology, warning symptoms, risk factors and treatment, and its determinants was assessed among general public and general practitioners (GPs) in a South Asian population. METHODS A cross-sectional study was conducted among relatives of nonstroke patients admitted to the apex tertiary-care hospital in Sri Lanka. Trained doctors administered pretested, structured, open- and close-ended questionnaires. A postal survey using self-administered questionnaires was conducted among all registered GPs in Sri Lanka. RESULTS The sample of general public (51.7% males; mean age = 40.7 years) from 21 of 25 districts of Sri Lanka was 840 (response-rate = 97.4%) while the sample of GPs (77.6% males; mean age = 59.63 years) was 98 (response-rate = 30%). Of the general public, 83.2% were aware of a vascular aetiology of stroke, stroke in any population. BACKGROUND Quadratus lumborum block (QLB) can reduce pain and opioid consumption after cesarean delivery. This systematic review investigated the effectiveness of QLB in reducing postoperative opioid use and its effect on pain scores compared to other analgesic methods after cesarean delivery. METHODS Six medical databases were searched from their inception to August 2019. Trials were eligible if parturients underwent cesarean delivery under spinal anesthesia (not epidural or general anesthesia). The primary outcome was postoperative opioid consumption during the first 24 and 48 h. Secondary outcomes included pain scores, patient satisfaction, and side effects. The risk of bias was assessed using the Cochrane tool. Where possible, meta-analytic techniques were used to synthesize data, presented as mean difference with 95% confidence interval (CI). RESULTS Twelve studies involving 904 patients were identified and analyzed. Opioid (intravenous morphine) consumption was significantly reduced with QLB when compared with placebo or no block during the first 24 h by 14.1 mg, (95% CI -20.8 to -7.5 mg) and 48 h by 20.8 mg, (95% CI -33.1 to -8.5 mg). Additionally, QLB significantly reduced 12-h pain scores at rest and during movement. However, this difference disappeared at 24 and 48 h. There was insufficient evidence regarding postoperative opioid use or pain scores with the use of QLB compared to intrathecal morphine. CONCLUSIONS The review findings show the superior analgesic effect of QLB when compared with systemic opioids in reducing postoperative opioid consumption, when intrathecal morphine is not administered. AIMS To assess longitudinal risk for atherosclerotic cardiovascular disease (ASCVD) and cost of healthcare resource utilization over 9 years in patients with or without newly diagnosed type 2 diabetes (T2DM) who had no ASCVD at baseline. METHODS This retrospective, longitudinal analysis of a large, nationwide US administrative claims database compared adults with newly diagnosed T2DM (n = 22,468) and a propensity score matched non-T2DM cohort (n = 22,468). Longitudinal risk of ASCVD and total annual healthcare costs were determined. Subgroup analysis was conducted for 3 age categories 18-44, 45-64, and 65+ years. RESULTS From 2006 to 2015, ASCVD was identified in a significantly greater percentage of patients in the T2DM versus non-T2DM cohort (43.2% vs 32.3%; Hazard ratio [HR] = 1.45, P  less then  0.001). Total annual healthcare cost was markedly higher in T2DM versus non-T2DM cohorts (48.4% higher at year 9). The differences between cohorts were most pronounced in patients aged 18-44 years. CONCLUSIONS This 9-year claims-based retrospective, longitudinal analysis showed a higher risk of ASCVD and higher healthcare costs in newly diagnosed T2DM patients versus those without T2DM, with highest relative risk and cost differences observed in younger patients.
