Intravenous tissue-plasminogen activator (IV-TPA) treatment in acute ischemic stroke (AIS) patients due to small vessel occlusion (SVO) has been debated because of its small expected benefit and symptomatic intracranial hemorrhage (SICH) risk. Furthermore, data on subgroups of SVO patients are limited. From a prospective multicenter stroke registry database, AIS patients due to SVO within 24 h from onset were selected. Efficacy outcomes were 3-month modified Rankin Scale (mRS) score 0-1 proportion and mRS score distribution. Additionally, subgroup analyses were conducted by age, sex, initial National Institute Health Stroke Scale (NIHSS) score, and presenting limb paresis. This study included 2482 patients: 193 in the IV-TPA group and 2289 in the control group. After adjusting covariates, IV-TPA treatment was associated with an increased mRS 0-1 outcome (adjusted OR [95% CI], 1.56 [1.06-2.29]; P = 0.0249), but was not significantly associated with a favorable mRS shift (1.33 [0.98-1.81]; P = 0.0709). SICH and 3-month death occurred in three (1.6%) and none in the IV-TPA group versus one (0.04%) and 16 (0.7%) in the control group. In subgroup analyses, the IV-TPA effect appeared significantly greater in patients aged ≥80 versus <80 for mRS score distribution (P interaction  = 0.012). This study showed that, in SVO patients, IV-TPA within 4.5 h may improve functional outcome with a low SICH risk. The benefit appeared more substantial in patients aged ≥80., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

As the benefit of thrombolytic therapy in acute ischemic stroke is time-dependent, a code stroke program needs to be implemented, maintained, and improved with continuous efforts to expedite thrombolytic therapy. We analyzed the long-term yield and efficiency of our code stroke program. Using a prospective single-center registry, we assessed the rates of stroke diagnosis and thrombolysis, door-to-CT scan and door-to-needle times, and annual trends in patients with code stroke activation between May 2007 and December 2011. Of the 791 patients with code stroke activation during the 4.7 year study period, 626 (79.1%) had a stroke, with 461 (58.3%) ischemic strokes and 165 (20.9%) hemorrhagic strokes. Along with an increase of code stroke activation (from 105/year to 236/year) and thrombolytic therapy volumes (from 24/year to 77/year), the rate of thrombolytic therapy among ischemic stroke patients increased from 33.3% to 59.2% (p for trend=0.0001). However, code activations for a non-stroke case also significantly increased (p for trend=0.0001). Door-to-CT scan time (p for trend=0.0011) and proportion of CT scan initiation ⩽ 25 minutes after arrival improved (p for trend=0.0022), and were 18.4 minutes and 76.7%, respectively, in 2011. However, the door-to-needle time and proportion of door-to-needle time ⩽ 60 minutes did not significantly improve, they were (43.3 minutes and 83.1%, respectively, in 2011). Our code stroke program yielded a high rate of detecting thrombolysis candidates and a continuous increase in rates of administration of thrombolytic therapy. These findings support the stroke team members' collaborative effort to treat more patients and to treat patients faster., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Background and Purpose: Intravenous tissue plasminogen activator (TPA) has limited efficacy in proximal large vessel occlusions. This study was to assess the safety and efficacy of mechanical thrombectomy with a retrievable Solitaire stent in acute large artery occlusions ., Materials and Methods: This is a single center study enrolling patients treated with Solitaire-assisted thrombectomy between November 2010 and March 2011. Inclusion criteria were severe stroke of National Institutes of Health Stroke Scale (NIHSS) score ≥10, treatment initiation within 6 hours from onset, and an angiographically verified occlusion of proximal middle cerebral artery (MCA) or internal carotid artery (ICA). The primary outcome was recanalization defined as Thrombolysis in Cerebral Infarct (TICI) reperfusion grade 2b/3. Secondary outcomes were good functional outcome at 3 months (modified Rankin Scale [mRS] ≤2), early substantial neurological improvement (NIHSS score improvement ≥8 at 24 hours), and symptomatic hemorrhagic transformation (SHT)., Results: Ten patients were consecutively enrolled: Age: 72.4 ΁ 5.7 years; female: 70%; baseline median NIHSS score: 19.5; and ICA occlusion in 50% and M1 portion of MCA occlusion in 50%. Six patients received intravenous TPA before intra-arterial treatment, and five patients were treated with adjuvant intra-arterial urokinase. Successful recanalization was achieved in 7 (70%) patients. Four (40%) patients had a good functional outcome at 3 months, and three (30%) patients had an early substantial neurological improvement. SHT occurred in two patients (20%), and 3-month mortality rate was 30%. There was no procedure-related complication., Conclusions: Mechanical thrombectomy with the Solitaire device can effectively recanalize proximal large vessel occlusions, and potentially improves clinical outcome.

Aims: This study was conducted to compare the effects of two years of lifestyle intervention to no intervention or one year of intervention on diabetes risk factors in male workers with impaired fasting glucose (IFG) or diabetes., Methods: We conducted a randomized lifestyle intervention trial designed to alter personal lifestyles among 123 industrial male workers (CG; control group, n=75; OIG; one-year intervention group, n=23; TIG; two-year intervention group, n=25). The intervention consisted of two parts, the main program (face-to-face counseling five times/12 weeks) and a follow-up program (e-mail counseling ten times/30 weeks). Assessments included biochemical characteristics, anthropometry and nutrient intake at baseline and after two years., Results: After two years, systolic blood pressure, HOMA-IR, HDL cholesterol and total energy intake (p<0.05) were reduced in the OIG group, while weight, body mass index, waist circumference, blood pressure, fasting plasma glucose (FPG), HbA1c and nutrient intake (total energy, carbohydrate, protein and sodium) were significantly decreased (p<0.05, respectively) in the TIG group. When compared to the CG, subjects in OIG and TIG showed significant improvements in the level of FPG and HbA1c (p<0.05)., Conclusions: Continuous lifestyle intervention for two years is more effective at improving diabetes risk factors than OIG.

Objectives: Plasma lipid profiles and Apolipoprotein E (ApoE) are established risk factors for cardiovascular disease (CVD). The knowledge of lipid profile may estimate the potential victims of cardiovascular disease before its initiation and progression and offers the opportunity for primary prevention. The most common ApoE polymorphism has been found to influence plasma lipid concentrations and its correlation with CVD has been extensively investigated in the last decade., Methods: The ApoE polymorphism and its influence on plasma lipid were investigated in healthy woman workers. The information on confounding factors was obtained through a self-administered questionnaire and ApoE polymorphism was investigated using PCR., Results: The relative frequencies of alleles E2, E3 and E4 for the study population (n=305) were 0.127, 0.750 and 0.121, respectively. ApoE polymorphism was associated with variations in plasma HDL-cholesterol lipid profile. In order to estimate the independent effects of alleles E2 and E4, as compared with E3, on lipid profile, multiple regression was performed after adjustment for confounding variables such as age, BMI, blood pressure, education status, insulin, fasting glucose, HOMA-IR, menopause. ApoE2 had a negative association with HDL cholesterol and ApoE4 had a positive association with LDL cholesterol., Conclusions: This study identified that the ApoE and CVD risk factors contribute to the lipid profiles, similar to other studies. The analysis including dietary intake and other gene in further studies may help to identify clear effects on lipid profiles as risk factor for CVD.

Worksite health promotion programs focusing on diet and lifestyle modification have been shown to improve health outcomes in workers. The purpose of this study was to investigate whether a 12-week worksite health promotion program shows different response of cardiovascular risk factors in subjects according to apolipoprotein E (Apo E) genotype and obesity level in 141 male Korean industrial workers. We hypothesized that the health changes of a 12-week intervention may not be the same within Apo E genotypes in nonobese and obese subjects. They received 5 face-to-face meetings based on their health profiles. In obese group carrying Apo E3 genotype, body mass index, body fat (%), waist circumference, waist-hip ratio, and systolic blood pressure were decreased, as well as intakes of energy (P = .000) and carbohydrate (P = .005). High-density lipoprotein cholesterol (P = .004) level was improved in individuals with the Apo E2 genotype. These beneficial effects were only observed in individuals with the Apo E2 or Apo E3 genotype. Multiple linear regression revealed that obesity was strongly correlated with waist circumference (P = .002), plasma total cholesterol (P = .037), and changes in dietary cholesterol intake (P = .011) in individuals with the Apo E3 genotype, whereas only changes in dietary fat intake (P = .044) was correlated in those with the Apo E4 genotype. Overall, the results of this study suggest that a health promotion program can be a useful method of improving cardiovascular risk factors and dietary intake in industrial workers with certain genotypes only. Therefore, further research is needed to develop a tailored, long-term worksite health promotion program based on genetic background.
