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: Hospital-acquired pneumonia (HAP) is one of the leading nosocomial infections and is associated with high morbidity and mortality. Numerous studies on HAP have been performed in intensive care units (ICUs), whereas very few have focused on patients in general wards. This study examined the incidence of, risk factors for, and outcomes of HAP outside the ICU. An incident case-control study was conducted in a 600-bed hospital between January 2006 and April 2008. Each case of HAP was randomly matched with 2 paired controls. Data on risk factors, patient characteristics, and outcomes were collected. The study group comprised 119 patients with HAP and 238 controls. The incidence of HAP outside the ICU was 2.45 cases per 1,000 discharges. Multivariate analysis identified malnutrition, chronic renal failure, anemia, depression of consciousness, Charlson comorbidity index ≥3, previous hospitalization, and thoracic surgery as significant risk factors for HAP. Complications occurred in 57.1% patients. The mortality attributed to HAP was 27.7%. HAP outside the ICU prevailed in patients with malnutrition, chronic renal failure, anemia, depression of consciousness, comorbidity, recent hospitalization, and thoracic surgery. HAP in general wards carries an elevated morbidity and mortality and is associated with increased length of hospital stay and increased rate of discharge to a skilled nursing facility.

    ABSTRACT: The interaction of La3+ to bovine serum albumin (BSA) has been investigated mainly by fluorescence spectra, UV–vis absorption spectra, and circular dichroism (CD) under simulative physiological conditions. Fluorescence data revealed that the quenching mechanism of BSA by La3+ was a static quenching process and the binding constant is 1.75×104Lmol−1 and the number of binding sites is 1 at 289K. The thermodynamic parameters (ΔH=−20.055kJmol−1, ΔG=−23.474kJmol−1, and ΔS=11.831Jmol−1K−1) indicate that electrostatic effect between the protein and the La3+ is the main binding force. In addition, UV–vis, CD, and synchronous fluorescence results showed that the addition of La3+ changed the conformation of BSA.
