Potential effectiveness of stored cord blood (non-frozen) for emergency use

Bone marrow has been used for a number of years to assist patients who have accidentally received potentially lethal levels of irradiation. The intent of the transplant is to replace the victim's own bone marrow that has been injured from the irradiation or to act as temporary support to allow the patient's own marrow to recover. Following the Chernobyl disaster, some victims received bone marrow that was HLA matched or partially matched. However, donor marrows were difficult to obtain in adequate numbers; as a substitute for bone marrow, frozen fetal liver cells were used as a source of hematopoietic stem cells. The use of fetal livers, however, was unsuccessful. Human umbilical cord blood, currently considered an excellent source of hematopoietic stem cells, was not used at Chernobyl. For several years, we have been able experimentally to keep SJL/J mice alive with the use of human umbilical cord blood after the animals received lethal levels of irradiation. This finding suggests that under certain conditions human cord blood does not have to be HLA matched to facilitate rescue from irradiation. In addition, there are reports of unmatched HLA cord blood being used successfully for marrow transplantation. If human cord blood does not have to be matched for HLA, there may be emergency cataclysmic circumstances where the availability of umbilical cord blood may be of considerable value. To simulate a clinical situation such as a nuclear accident, in which human cord blood might serve as a source of stem cells for marrow transplantation, we attempted to rescue immunocompetent mice after 900 cGY of irradiation with the use of (nonfrozen) human cord blood stored in a blood bank. The blood was stored under routine conditions (3–6 °C) for 5 and 7 days in special bags that allow transmission of oxygen. Following lethal levels of irradiation, the cord blood was administered to the animals and a significant survival rate was obtained.     

The experience of being 30–45 years of age and depending on haemodialysis treatment: a phenomenological study

The experience of being 30–45 years of age and depending on haemodialysis treatment: a phenomenological study The aim of this study was to describe how haemodialysis (HD) patients, between 30 and 45 years of age, experience their dependence on HD treatment. Nine patients undergoing HD treatment were interviewed. The transcribed texts were analysed according to Giorgi′s four basic principles. Being between 30 and 45 years of age and needing HD treatment meant experiencing a total lack of freedom, which was illuminated through the sub‐themes: a sense of fear, dependency on caregivers, time lost in dialysis, feelings of loneliness and the stress of being on the waiting list for a new kidney. The participants felt that being dependent on HD treatment was ‘not a real life’ and that they were experiencing a double life of sorts: the life of dialysis versus their ordinary life outside treatment. The dependency on HD treatment was also expressed as a feeling that life ‘stood still.’ The results also indicate that the participants expected to encounter competent healthcare professionals, and they emphasised the importance of providing support for younger HD patients by focusing on their ability to cope with their life situation.
