Red cell freezing by the American National Red Cross.

Red cells, frozen in the presence of glycerol, can be stored for years at -80C with excellent post-thaw recovery and in vivo survival. In addition to the benefits of long-term storage, the extensive washing associated with deglycerolizing removes essentially all platelets, plasma, microaggregates of cells and cell debris and there is some evidence of a reduction in the incidence of post-transfusion hepatitis. The majority of the white cells are lost during the processing. Three deglycerolizing methods, based on the Haemonetics Cell Washer, the IBM Cell Processor and the Fenwal Elutramatic, have been evaluated and data on comparative performance and costs are provided. The experience of the Red Cross Blood Program in processing over 90,000 units of frozen red cells is summarized.

[The Red Cross and Scandinavian disaster aid].

In 1970, the League of Red Cross Societies drew up a plan for the training of delegates in international relief work. The main tasks of the delegates can be divided into: 1) disaster relief, 2) war-time relief work, 3) assistance in organising national Red Cross societies. Special training of certain categories, e. g. doctors, is now being considered. In many relief operations it would be of value to have a doctor as an administrative delegate. It should be easier for the doctor than for a non-medically trained person to decide where and when medical aid should be administered.

Donor recruitment and blood collection costs for Red Cross Centers. An investigation of the economies of scale hypothesis.

This paper presents a statistical analysis of the hypothesis that there are economies of scale in the collection of blood. Based on a national sample of Red Cross collection centers, an analysis was conducted to determine the relationship between total costs of obtaining blood as well as its recruitment and collection components, and explanatory factors such as local costs, mobile units used, and scale of operations. Adjusting for other factors, our results indicate slight diseconomies of scale at all levels of operation: that is, as scale of operations increase, collection costs rise. Only the costs associated with the recruitment and collection functions are examined in this study.

Hepatitis B surface antigen: regional variation in sub-type ratio in the Canadian Red Cross donor population.

A total of 344 sera positive for hepatitis B surface antigen from volunteer blood donors at several Canadian Red Cross centres were subtyped for ad and ay specificity by counterelectrophoresis. Of the 50 sera from Toronto 21 (42%) were ad and 29 (58%) were ay; of the 95 from Montreal 82 (86%) were ad and 13 (14%) were ay; of the 199 from Quebec 179 (90%) were ad and only 20 (10%) were ay. The w and r specificities were also determined in 125 of the samples: 123 were w; the 2 samples of r specificity were from Toronto. On the other hand, among 45 sera from patients with acute hepatitis type B in Quebec 13 (29%) were ad and 33 (71%) ay.

The age, nutritional status and major diagnoses of outpatients at the Red Cross War Memorial Children's Hospital.

In 1961 a study of the age, sex, race, nutritional status and common diagnoses of children attending the Red Cross War Memorial Children's Hospital in Cape Town during one 12-month period was reported. A similar study was undertaken during two 2-week periods in 1972--1973. Comparison of the studies shows: (i) that a greater number of older children attended the hospital in 1972/1973; (ii) that the proportion of malnourished children whose percentage of expected weight for age was less than 66% had decreased from 8--10% to 5,5--6%; and (iii) that the overall pattern of disease had not changed appreciably, most of the children presenting with minor or preventable conditions.
