Serum albumin level and nosocomial pneumonia in stroke patients
ABSTRACT Hypoalbuminemia is associated with increased risk of infections. The aim of this study was to determine if serum albumin level is an independent predictor of nosocomial pneumonia in stroke patients. Data of 705 consecutive ischemic stroke patients admitted within 24 h after stroke onset were analyzed retrospectively. Serum albumin level was measured within 36 h after stroke onset. Nosocomial pneumonia was found in 10.5% of stroke patients. Patients with pneumonia had significantly lower serum albumin level than those without pneumonia (31.9 +/- 7.5 g/l vs. 35.5 +/- 6.9 g/l) and serum albumin level was associated with risk of pneumonia on multivariate analysis (OR: 0.95, 95% CI: 0.91-0.98). Our results show that serum albumin level is an independent predictor of nosocomial pneumonia in stroke patients.

ABSTRACT: Hypoalbuminemia in acute stroke patients is associated with increased mortality and morbidity. The aim of our study was to determine the frequency and correlates of hypoalbuminemia in unselected cohort of patients with acute cerebral infarction. Prospective study. University hospital. Seven hundred and five consecutive ischemic stroke patients. Albumin and other serum protein fractions were measured within 36 h after stroke using electrophoresis. Hypoalbuminemia defined as serum albumin level <35 g/l was found in 45.5% of patients. Serum albumin level correlates significantly with age (r=-0.13, P<0.01), Scandinavian Stroke Scale score (r=0.14, P<0.01), body temperature on admission (r=0.14, P<0.01), leukocyte count (r=-0.17, P<0.01), fasting glucose (r=-0.16, P<0.01), total cholesterol (r=0.14, P<0.01), alpha1-globulin (r=-0.48, P<0.01), alpha2-globulin (r=-0.49, P<0.01), beta-globulin (r=-0.26, P<0.01) and gamma-globulin (r=-0.35, P<0.01). Hypoalbuminemia is a frequent finding in acute stroke patients and it is associated with more severe stroke and pro-inflammatory pattern of serum protein electrophoresis.European Journal of Clinical Nutrition 12/2007; 61(11):1318-22.

Conference Paper: Issues in Algebraic Control Theory[Show abstract] [Hide abstract]
ABSTRACT: A unified view of recent results in the algebraic theory of linear, time-invariant multiinput-multioutput control systems is presented, with emphasis on the unity-feedback system (one-degree-of-freedom design) and the more general two-input two-output plant and compensator configuration (four-degrees-of-freedom design). The issues of stability, parametrization of all stabilizing compensators, achievable input-output maps and decoupling are discussed.American Control Conference, 1988; 07/1988
