Willingness to Donate Human Samples for Establishing a Dermatology Research Biobank: Results of a Survey

Social differentiation of the perception and human tissues donation for research purposes

The willingness to donate human biological material for research purposes is shaped by socio-cultural factors; however, there is a lack of studies analysing the social perception of different human tissues, which may affect such willingness. This study aimed to distinguish different sociocultural categories of human tissues and types of potential donors based on their willingness to donate material. Quantitative research was conducted on a sample of 1,100 adult Poles representative in terms of sex, place of residence and education. According to the study, people were most willing to donate urine (73.9%), blood (69.7%), hair and tears (69.6%) and the least willing to donate post-mortem brain fragments (20%), sperm (males; 36.4%) and egg cells (females; 39.6%). A factor analysis revealed four sociocultural categories of donated tissues: irrelevant, redundant, ordinary and sensitive. Based on these sociocultural categories of tissues, four types of donors were identified: reluctant, highly cooperative, average cooperative and selectively cooperative. The willingness to donate human samples for research is shaped by the sociocultural perception of different body parts and tissues. The lower the sense of “personal relationship” with a specific type of tissue, organ or part of the body, the higher the motivation to donate such biological material for research purposes. Additionally, the willingness to donate is mostly shaped by social trust in physicians and scientists, and potential donors’ engagement in charity activities.

An Update on the Italian Twin Register: Advances in Cohort Recruitment, Project Building and Network Development

The Italian Twin Register has been in place for more than 10 years. Since its establishment, it has been focusing, on the one hand, on a continuous update of the existing information, and on the other hand, on new phenotypes and sample collection. Demographic data on about 140,000 twins have been updated using the municipality registries. The Italian Twin Register has been carrying out several new studies during the last few years. A birth cohort of twins, Multiple Births Cohort Study, has been started and the enrolment is ongoing. For this cohort, data on pregnancy and birth are collected, and periodical follow-ups are made. DNA is being collected for the twins and their parents. In the area of behavioral genetics, most efforts have been directed to psychological well being assessed with self-reported tools. Research on age-related traits continues with studies on arteriosclerosis development, early biomarkers in mild cognitive impairment, and the relation between lifestyle habits and mutagen sensitivity. The Italian Twin Register biobanking has grown in its size and in its know-how in terms of both technical issues and ethical procedures implementation. Furthermore, attitudes toward biobank-based research, together with willingness and motivation for donation, are being investigated. A valuable key resource for the Italian Twin Register is the possibility of linking twin data with disease registries. This approach has been yielding several important results, such as the recent study on the heritability of type 1 diabetes.
