Studies have suggested a positive relationship between prosociality and well-being. attempt to analyze the relationship between blood donation and subjective well-being, and try to figure out the moderators and mediators. Also, the investigators would like to compare difference of subjective well-being between donors who are explicitly presented with information that the participants' blood has saved patient's life and those who are not.
The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. Urgent recruitment of blood donors is therefore planned during the period from 30 April to 10 May via emergency recruitment SMS . This study has been designed to compare which information extraction frameworks would be more sensitive to blood donors in emergency situations.
In December 2019, an unknown pneumonia rapidly spread in Wuhan, China, a new coronavirus, 2019 novel coronavirus (2019-nCoV), aroused the attention of the entire world. On January 31, 2020, World Health Organization (WHO) announced the outbreak of Coronavirus Disease 2019 (COVID-19) in China as a Public Health Emergency of International Concern. The number of volunteer non-remunerated blood donors decreased because of quarantine, caring for relatives, and fear of exposure to COVID-19. Due to the blood shortage, patient blood management and cessation of elective surgery are contributing to decreased demand, but sepsis may increase requirements and significant reductions will not be possible in areas such as trauma, cancer patients, hereditary haemolytic anaemias and childbirth. Therefore, recruiting enough blood donors during the epidemic is vital for public health in China, and also worldwide. In order to assess the effects of a questionnaire on blood donor recruitment, the investigators designed two kinds of self-administered, standardized and structured questionnaires. In addition of the basic socio-demographic characteristics, one questionnaire includes the information of precautions of blood donation during epidemic, and the other dose not. The questionnaires were randomly sent to ever blood donors, and the same number of ever blood donors are coded as control.
This study will follow blood transfusion recipients for 6 to 9 months following transfusion to monitor the quality and safety of blood transfusion. Improved viral testing and careful donor screening in the last several years has dramatically reduced the rates of transfusion-related HIV and hepatitis. Nevertheless, ongoing surveillance of transfusion-related infections is essential to maintain a high safety standard and to determine the transfusion risk of other infectious agents, such as cytomegalovirus, Epstein-Barr virus, parvovirus B-19, HHV-8 (Kaposi s sarcoma virus) and other possible hepatitis viruses that might be blood-transmitted. Transfused patients blood will be tested for various infectious agents. Their blood samples and blood samples from their donors will be frozen and stored in a repository so that any new infectious agent can be rapidly evaluated for its danger to the safety of the blood supply. Adult patients at the National Institutes of Health and children at the Children s National Medical Center who are scheduled to receive a blood transfusion or to undergo surgery for which a blood transfusion may be needed are eligible for this study. All participants will have a 20- to 25-milliliter (about 2 tablespoonfuls) blood sample drawn before their transfusion and again at 1, 2, 4, 12 and 24 weeks after the transfusion. Patients who are transfused on more than one occasion over the course of the study will provide three additional monthly samples. Patients who develop a transfusion-transmitted infection during the study will provide up to four more samples to study the infection and its effects. Participants will complete a brief questionnaire at the end of the study regarding prior blood transfusions and the development of any illnesses, such as hepatitis, that might have been caused by the transfusion.
