Background: Blood donation is a major concern to the society as donated blood lifesaving for individuals who need it. In Libya, concept of voluntary donors almost non-existent due absence donor motivation and retention strategies. The objective this study was assess factors leading reluctance from among general population in Derna. Methods: Descriptive cross-sectional survey design used collect...

1. Of 96 alcoholics admitted for detoxification, 48% were hypertensive (systolic blood pressure greater than 140 mmHg and/or diastolic pressure greater than 90 mmHg). 2. Elevation of both systolic and diastolic blood pressures was related to the severity of alcohol-withdrawal symptoms. 3. After these symptoms had abated only 9% of patients remained hypertensive. 4. Blood pressure remained norma...

A total of 1166 male participants (ages 23--80 years) of the Normative Aging Study who had baseline blood pressure less than 140/90 mm Hg were followed prospectively for 10 years. Blood pressures were taken at 5- and 10-year follow-up examinations. Multiple linear regression analysis indicated that baseline levels of systolic pressure, hematocrit, subscapular skinfold thickness and age were sig...

The activity of blood clotting factors has been investigated in cerebrospinal fluid. No cephalin-like activity was found in cerebrospinal fluid but prothrombin activity averaged about 0.5% of normal plasma activity. The activity of factor VII was negligible in almost all cases. The activity of antihaemophilic factors showed great variation but in the majority of cases it did not exceed 1% of no...

OBJECTIVE To analyze the profile of blood transfusion reactions in children and to identify the involved factors. METHODS This was a cross-sectional study in a tertiary pediatric teaching hospital from the public healthcare system, involving all children admitted from January to July of 2011 (5,437), of which 1,226 received blood transfusions, constituting the sample. A documental study was p...

To assess the reproducibility of ambulatory blood pressure, we recorded 24-hour blood pressure twice 3 months apart in 508 hypertensive subjects participating in the HARVEST trial using a noninvasive technique. Blood pressure was measured every 10 minutes during the daytime and 30 minutes during the nighttime. Reproducibility was better for ambulatory than for office blood pressure. It was grea...

The tissues of the body decompose at different rates after death, but little is known of how long red cell antigens persist in the cadaver, this despite the data available on the decay of agglutinins in stored blood samples and on the appearance of false antibodies and panagglutinability when they become infected (Thomsen, 1927; Steffan, 1932). Latterly the stability of red cell agglutinogens i...
