BACKGROUND Pregnant women constitute a high risk group for iron deficiency. Maternal iron deficiency and particularly iron deficiency anaemia may be associated with detrimental effects on maternal and infant function and particularly with a higher risk of preterm delivery and delivery of low birth weight neonates. Objective of this study was to assess and compare the iron status of normal healt...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

Background: Considering the susceptibility of preterm infants to disturbances of vital signs, this study was conducted to investigate the effects of using plastic covers on regulation of vital signs in preterm neonates.Methods: This randomized, cross-over, clinical trial was carried out on 80 preterm infants admitted to neonatal intensive care unit (NICU) of Taleghani Hospital, Tabriz, Iran. Th...

Background: The quantitative contribution of cardiopulmonary bypass (CPB) to respiratory dysfunction after cardiac surgery is not documented and the effect of the use of bilateral internal mammary artery (IMA) grafts is not clear. Methods: One hundred and seventy-®ve patients undergoing CABG with (CPB, n ˆ 150) and without (NOCPB, n ˆ 25) CPB were studied. PMN elastase (as a marker of the syste...

OBJECTIVE To investigate the frequency of pulmonary hypertension (PH) and clinical parameters associated with PH in sarcoidosis patients. METHODS A prospective, observational study was performed on 246 consecutive Japanese sarcoidosis patients followed up at the outpatient sarcoidosis clinic in the Central Clinic of Kyoto. The patients were evaluated for PH by Doppler echocardiography. Among ...

this paper is a report on the synthesis of the fe3o4@ag core-shell with high saturation magnetization of magnetite nanoparticles as the core, by using polyol route and silver shell by chemical reduction. x-ray diffraction (xrd) and fourier transform infrared spectroscopy analyses confirmed that the particles so produced were monophase. the magnetic properties of the product were investigated by...

Background. Ferritin and the percentage of transferrin saturation (TS) are established parameters with which to evaluate endogenous iron availability during treatment of renal anaemia with recombinant human erythropoietin (rHuEpo). Zinc protoporphyrin (ZPP) has been proposed as another valid marker in this setting. Methods. We determined the following parameters in 127 patients, including 117 h...

Phospholipids in plasma and erythrocytes of rats exposed to 100% oxygen for 3 days were analyzed. Exposed rats contained lower quantities of several phospholipids in both plasma and erythrocytes than in matched controls. Pronounced decreases were found in phosphatidylcholine and lysophosphatidyl choline. The proportion of disaturated species in erythrocyte phosphatidylcholine was significantly ...

The computerization of SaO2 recording during polysomnographic monitoring allows the construction of a diagram expressing the percentage of TIB spent at different steps in saturation. We studied the value of this diagram in three groups of male patients: (1) nine healthy subjects (all volunteers); (2) 25 patients with COPD who had a mean daily SaO2 of 92.3 +/- 1.3 percent; and (3) 25 patients wi...
