THE STUDY OF BIOMARKER HOMOCYSTEINE AS RISK FACTOR IN ACUTE CEREBRAL STROKE PATIENTS OF WESTERN RAJASTHAN

Abstract We chemically synthesized an isotopically labeled internal standard, isodesmosine-13C3,15N1, and established an isotope-dilution LC-MS/MS method. Plasma concentrations of desmosine and isodesmosine in acute cerebral stroke patients and healthy controls were determined. The desmosine concentration was markedly higher in plasma from acute stroke patients compared with healthy controls. Desmosines are novel biomarkers for evaluating the extent of vascular injury after acute cerebral stroke.

The Difference

Introduction: During the past decades there has been a great progress in neuroimaging methods. Cranial computed tomography is part of the daily routine now and its use allows a fast diagnosis of parenchymal hemorrhage. However, before the availability of computed tomography the differentiation between ischemic and hemorrhagic stroke was based on patient history, physical examination, percutan angiography and cerebrospinal fluid sampling, and the clinical utility could be evaluated by autopsy of deceased patients. Aim: The authors explored the diagnostic performance of cerebrospinal fluid examination for the diagnosis of ischemic and hemorrhagic stroke. Method: Data of 200 deceased stroke patients were retrospectively evaluated. All patients had liquor sampling at admission and all of them had brain autopsy. Results: Bloody or yellowish cerebrospinal fluid at admission had a positive predictive value of 87.5% for hemorrhagic stroke confirmed by autopsy, while clear cerebrospinal fluid had positive predictive value of 90.7% for ischemic stroke. Patients who had clear liquor, but autopsy revealed hemorrhagic stroke had higher protein level in the cerebrospinal fluid, but the difference was not statistically significant (p = 0.09). Conclusions: The results confirm the importance of pathological evaluation of the brain in cases deceased from cerebral stroke. With this article the authors wanted to salute for those who contributed to the development of the Hungarian neuropathology. In this year we remember the 110th anniversary of the birth, and the 60th anniversary of the death of professor Kálmán Sántha. Professor László Molnár would be 90 years old in 2013. Orv.

Stroke In Young

Abstract Background Etiologies of acute ischemic stroke in young adults are heterogeneous. Middle cerebral artery (MCA) stenosis is a common finding in Asians which may be an important cause of stroke in young adults. However, studies of stroke in young Asian populations are rare. Our study was to investigate the prevalence and outcome of young stroke patients with MCA stenosis in Chinese populations. Methods Young patients with MCA territory infarction between January 2013 and September 2018 were retrospectively recruited. Subjects were defined as stenosis group (MCA stenosis ≥50%) and no-stenosis group (MCA stenosis<50% or no stenosis) by their MCA stenosis. For patients in stenosis group, they were categorized as uni-MCA stenosis subgroup and multiple stenosis subgroup. Demographic data, risk factors, imaging feature and complications were compared between groups. Prevalence of MCA stenosis and risk factor score (score ≥ 2 or 3) in different age groups were investigated. Modified Rankin Scale (mRS) was used for evaluating functional outcome at discharge (unfavorable outcome: 3–6). Binary logistic regression was performed to determine independent risk factors of unfavorable outcome. Results Two hundred forty-nine young stroke patients were included in our study and 110 (44.2%) patients were defined as stenosis group. 55 (50%) patients were categorized as uni-MCA stenosis subgroup and 55 (50%) were multiple stenosis subgroup. The most common traditional vascular risk factors included hypertension, hyperlipemia, smoking, hyperhomocysteinemia and alcohol consumption. Prevalence of risk factor score ≥ 2 or 3 increased with age, but not incidence of MCA stenosis. By TOAST classification, the most common etiologies were large-artery atherosclerosis (41.0%) and small vessel disease (33.7%). Compared with no-stenosis group, patients in stenosis group were more likely to have large territorial infarct, develop complications and have unfavorable outcome. No significant difference was found between patients in uni-MCA stenosis and multiple stenosis subgroups except history of stroke/TIA, risk factor score ≥ 3 and silent infarct. By logistic regression, hypertension (OR = 3.561; 95%CI, 1.494 to 8.492; p = 0.004), NIHSS scores at admission (OR = 1.438; 95%CI, 1.276 to 1.620; p = 0,000) and infarct size (p = 0.015) independently predicted unfavorable outcome. Conclusions Forty-four point two percent young Chinese adults with MCA territory infarction had MCA stenosis. Prevalence of MCA stenosis did not increase with age. Patients with MCA stenosis had worse clinical outcome, however, only hypertension, NIHSS scores at admission and infarct size were independent predictors.

Abstract Cerebral stroke is one of the most important issues for modern medicine. Despite the fact that numerous activities have been undertaken for the purpose of raising awareness and significance of prevention, this condition still remains one of the main reasons behind disability. The objective of the work was to assess the effects of the type of therapy, age and period from the incident occurrence, on the progress of rehabilitation of imbalance and body stability observed in a group of researched patients, on the basis of results obtained according to the Berg Balance Scale, tandem balance test, Kwolek’s loading symmetry index and Timed Up and Go test. The test group comprised of 55 post-stroke patients. The group consisted of 29 women (52.73%) and 26 men (47.27%). The average age of the subjects was 61.02 years (age range between 33-85 years). A number of the patients were subjected to rehabilitation with the use of classic kinesitherapy, whereas the remaining group underwent rehabilitation based on the proprioceptive neuromuscular facilitation method (PNF).

Facility Level

Background: The Veterans Health Administration has multiple quality improvement activities directed at improving vascular risk factor control. We sought to examine facility quality of blood pressure (BP) control (<140/90 mm Hg), lipid control (LDL-cholesterol <100 mg/dL) and glycemic control (HbA1c <9%) in the one-year after hospitalization for ischemic stroke or acute myocardial infarction (AMI). Methods: We assembled a retrospective cohort of patients hospitalized with stroke or AMI (fiscal year 2011). Facilities were included if they admitted ≥25 stroke patients and ≥25 AMI patients. A facility-level consolidated measure of vascular risk factor control was calculated for the 3 processes of care (number of passes divided by number of opportunities). Results: A total of 2432 patients had a new stroke and 4873 had a new primary AMI (at 75 facilities). Stroke patients had worse vascular risk factor control than AMI patients (mean facility rate on consolidated measure: stroke, 70% [95%CI 0.68-0.72] vs AMI, 77% [0.75-0.78]). The greatest disparity between stroke and AMI patients was in hypertension control: at 87% of hospitals, fewer stroke patients achieved BP control than AMI patients (mean facility pass rate: stroke, 41% vs AMI, 52%; p<0.0001). Overall there were no statistical differences for stroke versus AMI patients in facility-level hyperlipidemia control (71% vs 73%, p=0.33) and glycemic control (79% versus 82%, p=0.24). AMI patients had more outpatient visits than stroke patients in the year after discharge [AMI: mean 7.9 visits (standard deviation 6.1)]; stroke: mean 6.0 visits (standard deviation 4.5; p<0.0001].); the primary difference in outpatient utilization was additional cardiology visits for AMI patients (2.5 visits with cardiology per AMI patient vs 0.4 visits per stroke patient; p<0.001). Conclusions: These results demonstrated clinically substantial disparities in hypertension control among patients with stroke vs patients with AMI. It may be that cardiologists provided risk factor management to AMI patients that stroke patients did not receive. The etiology of these observed differences merits additional investigation.

Background and purpose: Hypertension is the most prevalent risk factor for acute and chronic cerebrovascular disease. As patients with resistant hypertension are a subgroup with even higher risk, we aimed to evaluate the burden of microangiopatic disease and functional outcome in subjects with stroke and difficult to treat hypertension. Design and method: acute ischemic stroke patients were prospectively included in a multidisciplinary secondary stroke prevention program. Pre-stroke vascular risk factor profile and control were obtained from electronic medical records and chronic vascular disease burden was assessed on admission MRI. Functional and cognitive evaluation were performed one-month after stroke. Results: 1327 patients (16% with resistant hypertension) were included from September 2009 and December 2015. Patients with resistant hypertension were older (80±8 vs 77±10, p 0.0004), with higher prevalence of obesity (62% vs 50%, p 0.001), metabolic syndrome (52% vs 38%, p 0.0001) and history of atrial fibrillation (27% vs 16%, p 0.0001). There was a direct relationship between resistant hypertension and the severity of chronic microvascular lesions, and also with functional and cognitive outcomes (table). Conclusion: Hypertension increases vascular events risk, even more in the setting of resistant hypertension. Requirement of a therapeutic strategy involving combination of multiple drugs generally indicates more severe underlying hypertensive disease. It is possible that mechanisms of endothelial dysfunction responsible of the neurovascular unit damage might remain active despite achieving blood pressure target.
