Parents' knowledge, awareness and attitudes of cord blood donation and banking options: an integrative review

Knowledge and attitude of dental school faculties towards stem cell therapies and their applications

Background

Stem cells are characterized by their ability to self-renew and differentiate across multiple lineages. Knowledge about these cells and their potential is an important factor driving people to support their use. Therefore, we aimed to evaluate the knowledge and attitudes regarding stem cell therapies, education, and donation among faculty members of the College of Dentistry at King Saud University, Saudi Arabia.

Methods

A self-completed questionnaire was distributed among the faculty members, in which questions about demographic data, basic knowledge of stem cells as well as attitudes towards education and participation in stem cell-related research, and tissue donation were raised.

Results

A total of 102 participants responded to the questionnaire. Most participants (62.7%) ranked their stem cell knowledge as basic, despite correctly answering most of the knowledge questions. More than half of faculty mentioned a lack of stem cell-related activities in their courses (59.8%), and most showed strong support for including related education in postgraduate programs (71.6%). Noteworthy, 64% of participants reported interest in stem cell research and 74.5% were willing to donate their tissue for research purposes. The mean ranks of knowledge scores were significantly higher in subjects who have related lectures in undergraduate courses (p < 0.05), and those with high interest in research participation and tissue donation (p < 0.0001), and (p < 0.05) respectively. Most participants (>60%) were not aware about the current applications of stem cell research and therapy in Saudi Arabia.

Conclusion

Most participants had an acceptable degree of knowledge about stem cells and showed a positive attitude to their education and participation in research. Additionally, knowledge scores have significantly and positively influenced those attitudes. More effort is required to promote the presence of local facilities for researchers to participate in stem cell-related research. The results of this study can be used as a foundation for evidence-informed policymaking within dental schools and research institutions.

Hybrid cord blood banking in a private-public-partnership: Women's perspectives

BACKGROUND

The increasing demand for umbilical cord blood (UCB) used in stem cell transplantation led to the establishment of cord blood (CB) banks worldwide. These include public foreign donor banks and private family-directed donor banks. Recently, our department has introduced a third banking model within a private-public-partnership. This hybrid banking allows for storage of family-directed CB units, while also getting Human leukocyte antigen (HLA)-typed and included in the national stem cell donor registry. So if the need arises, the HLA-compatible CB unit can be released to an unrelated recipient as a foreign donor stem cell graft.

OBJECTIVES

The aim of this study was to evaluate women's perspectives on the different CB banking options as well as retrospective satisfaction with their decisions.

METHODS

We performed a prospective survey study in postpartum women, using a validated questionnaire.

RESULTS

A total of 157 women were included in this survey study; 68% of them decided to have their UCB stored or donated. Among those women, 25% of them opted for hybrid storage, 72% of respondents stored UCB publicly, and 3% decided for private family-directed storage.

CONCLUSIONS

Our study shows the potential of hybrid banking as an attractive UCB storage option, as an alternative to family-directed banking rather than a substitute for public donation. Hybrid storage potentially combines advantages of family-directed banking as well as unrelated CB donation expanding the number of registered CB units available for transplantation and giving every pregnant woman the possibility to store UCB.

Exploring Parental Knowledge, Attitudes, and Factors Influencing Decision-Making in Stem Cell Banking: Rising the Future of Medical Treatment

BACKGROUND AND OBJECTIVES

Stem cell banking (SCB) is a promising area of modern medicine with the potential to yield innovative treatments and cures. To effectively educate parents and implement laws and regulations that address parental concerns and encourage informed decision-making, it is imperative to emphasize parental viewpoints and their consequences for future healthcare. The study aims to establish the Saudi Arabian population's level of understanding regarding SCB and to comprehend the elements influencing parental knowledge, attitudes, and SCB decision-making processes.

METHODOLOGY

A cross-sectional study was conducted among the population in the Makkah region of Saudi Arabia. Demographic data, knowledge levels, attitudes, and decision-making variables were gathered from 380 respondents.

RESULTS

The study reveals a lack in their comprehension of the objectives and possible uses of SCB, together with the main sources of information on those banks and conveniently available banking choices. It showed varied results regarding attitudes about considering an SCB for their children. In addition, the majority of respondents had not made a consent decision about SCB for their children. It also illuminates the factors that could influence participants' decisions about SCB for their children and shows that a lack of information and understanding is the main obstacle faced by parents regarding SCB. It highlights that participants were generally in favor of learning more about SCB for their children.

CONCLUSIONS

This study broadens our understanding of parental decision-making toward SCB and clarifies the elements influencing parents' opinions and worries and offers significant ramifications for lawmakers, medical professionals, and SCB. These implications can be utilized to enhance communication strategies, create instructional programs, and ease the fears of concerned parents.

Peripartum women's perspectives on research study participation in the OneFlorida Clinical Research Consortium during COVID-19 pandemic

Introduction

The COVID-19 pandemic created an unprecedented need for population-level clinical trials focused on the discovery of life-saving therapies and treatments. However, there is limited information on perception of research participation among perinatal populations, a population of particular interest during the pandemic.

Methods

Eligible respondents were 18 years or older, were currently pregnant or had an infant (≤12 months old), and lived in Florida within 50 miles of sites participating in the OneFlorida Clinical Research Consortium. Respondents were recruited via Qualtrics panels between April and September 2020. Respondents completed survey items about barriers and facilitators to participation and answered sociodemographic questions.

Results

Of 533 respondents, most were between 25 and 34 years of age (n = 259, 49%) and identified as White (n = 303, 47%) and non-Hispanic (n = 344, 65%). Facebook was the most popular social media platform among our respondents. The most common barriers to research participation included poor explanation of study goals, discomforts to the infant, and time commitment. Recruitment through healthcare providers was perceived as the best way to learn about clinical research studies. When considering research participation, "myself" had the greatest influence, followed by familial ties. Noninvasive biological samples were highly acceptable. Hispanics had higher positive perspectives on willingness to participate in a randomized study (p = 0.009). Education (p = 0.007) had significant effects on willingness to release personal health information.

Conclusion

When recruiting women during the pregnancy and postpartum periods for perinatal studies, investigators should consider protocols that account for common barriers and preferred study information sources. Social media-based recruitment is worthy of adoption.

An overview of cord blood stem cell transplantation in Hong Kong

Haematopoietic stem cell graft derived from cord blood is standard therapy for several haematological malignancies and other diseases. The study reports cases of public and private (family) cord blood biobanking services and the related hematopoietic stem cell transplantation ever performed in Hong Kong. The published original research papers and review articles from inception to Nov 2022 have been searched for on Pubmed, Microsoft Academic Search, and Google Scholar to identify reports on existing or terminated cord blood biobanking and transplantation service in Hong Kong. Moreover, all data publicly available on the official websites of the local cord blood banks and local mainstream media has been analysed. The public Hong Kong Red Cross Blood Transfusion Service delivers the highest quantity of haematopoietic stem cell transplants. Among the private sector, HealthBaby releases the most cord blood units for clinical use in diseases in both autologous and allogeneic administration, followed by Cordlife HK.  Both public and private (family) cord blood biobanks have been and continue to contribute to the Hong Kong cord blood donor registry. However, the growth of the cord blood inventory is detrimental to donor-recipient matching for lifesaving therapy.

Stem-cell therapy in neonates - an option?

Within the fast-growing field of regenerative medicine stem-cell therapy is well established in various hematologic and immunologic diseases and has received a recent substantial boost from the introduction of gene editing and gene transfer technologies. In neonates, for example, regenerative medicine may benefit those with congenital or acquired disease due to prematurity or perinatal hypoxia-ischemia. We compare and contrast the two main approaches - autologous vs. allogeneic - and summarize the recent advances and applications of interventional stem-cell research in perinatally acquired disorders such as intraventricular hemorrhage, hypoxia-ischemia and stroke. After discussing stem-cell sources and routes of administration, we conclude by highlighting the key opportunities and obstacles in this exciting field.

Undergraduate medical students' perceptions regarding stem cells: Is there a need for incorporating a stem cells elective course in the academic curriculum?

Stem cell therapy has recently progressed from the preclinical to the early clinical trial arena for a variety of diseases. Moreover, the medical students lack the deep and full understanding of its significance and potential as the promising future cure for diverse diseases worldwide. This study aims at evaluating the knowledge, awareness, and perception of medical students as far as stem cells applications are related in the medical field. A cross-sectional survey was carried out using online questionnaires, which were distributed via e-mail to cover all medical faculties in Jordan. The data show that medical students are supportive of using stem cells and their therapeutic applications, and most of them are willing and enthusiastically want to improve their knowledge about stem cells; however, due to the tight schedule and the lack of an elective course about stem cells in the curriculum, many of them are not ready to undergo further training in regenerative medicine unless it becomes part of the assigned training and part of the learning objectives for medical students. These findings indicated the need to update the medical school curriculum with new hits in medicine and expand the range of courses offered for medical students so they can be up-to-date with the quick advances in different medical disciplines.

Umbilical Cord Blood Banking: An Update For Childbirth Educators

To make an informed decision on umbilical cord blood banking or donation during birth, families need evidence-based, quality information on this alternative. Cord blood banking often refers to private banking, while donation generally refers to public banking. Research has shown that expectant parents do not have sufficient understanding of the cord blood banking process, umbilical cord stem cell transplants, uses of these cells, or options. Research also shows that birthing families desire that information to come from a reliable healthcare provider resource, such as a childbirth educator. Therefore, this article will offer information for use by childbirth educators, nurses, or other birth workers to increase awareness and knowledge on the topic of umbilical cord blood banking and donation.

Peddling promise? An analysis of private umbilical cord blood banking company websites in Canada

Private umbilical cord blood banking is growing around the world. A family's decision to bank cord blood publicly or privately can be influenced by numerous sources including healthcare practitioners, personal networks, the popular press, social media and marketing discourse from private entities. Issues have been raised concerning how private banks market their services, particularly with regards to the likelihood of use and for what purposes cord blood can be used. The objective of this study was to analyze the marketing on the seven company websites offering private cord blood storage in Canada. We performed a mix of content and general qualitative analysis on the seven websites. Our analysis shows substantial hype around cord blood uses, amplifying the promise of speculative uses and distorting the likelihood of use. Findings show that this promotional messaging often deploys communication strategies which draw on testimonials and emotionally-charged narratives. Questions should be asked about whether the promissory aspects of these websites constitute breaches of Canadian law or regulation. Careful monitoring of the private cord blood space is important for ensuring that the Canadian public is adequately and accurately informed of the services being offered.

Knowledge, Awareness, and Attitudes toward Umbilical Cord Blood Biobanking

BACKGROUND: Umbilical Cord Blood (UCB) stem cells are a non-invasive, effective alternative source of hematopoietic stem cells for the treatment of a variety of diseases. AIM: The aim of the study was to research knowledge, awareness, and attitudes of the general public and health professionals regarding the UCB storage. MATERIALS AND METHODS: A cross-sectional study was conducted with an online survey (n = 408) using the snowball method. RESULTS: A majority of respondents declared that they were not aware of UCB banking; however, people with an academic background in healthcare have a greater awareness of UCB banking. A subjective assessment found that their knowledge of UCB banking is better than that of non-professionals, however, they exhibited better knowledge and understanding of UCB use and banking in only a few aspects. People with an academic background in healthcare have a more polarized attitude toward cord blood banking and a higher percentage are unwilling to pay for UCB banking services. However, their preferences regarding public/private UCB banking do not differ significantly from those of non-professionals. CONCLUSION: Here, we show that there is not much difference between the laic and professional categories in terms of knowledge about the specific purpose and characteristics of UCB storage.

Determinants of the intention to donate umbilical cord blood in pregnant women

Background and Objectives

Umbilical cord blood (UCB) donation is a behaviour promoted by many countries' health systems. However, UCB donation is not a widespread behaviour among expectant mothers, and little is known about the reasons that may lead to it. The aim of the present study was to analyse the contribution of Theory of Planned Behaviour (TPB) variables among both primiparous and multiparous women in predicting intention to donate UCB.

Materials and Methods

Three hundred seventy‐six expectant mothers completed questionnaires that captured sociodemographic data, parity, previous donation, attitudes, subjective norms, perceived behavioural control (PBC) and intention to donate UCB. Multigroup analysis structural equation modelling was conducted using Mplus (version 8.02).

Results

Multigroup path analyses showed that intentions were strongly predicted by subjective norms and moderately predicted by positive attitudes and PBC in both primiparous and multiparous women. TPB constructs explained 71% of the variance in intentions for both groups.

Conclusions

Future interventions to increase intention to donate among primiparous and multiparous women could primarily consider the influence of partner and significant others in determining positive intentions and secondarily target increasing positive attitudes and perceptions of control.

Women's attitude towards umbilical cord blood banking in Poland

Umbilical cord blood (UCB) is considered as a valuable potential source of hematopoietic stem and progenitor cells. A process of collecting and storing UCB in the immediate period after the birth is called UCB banking. The study was conducted in order to determine women's knowledge, awareness, preferences and attitude towards UCB banking in Poland, considering the sociodemographic and obstetric factors. A cross-sectional, self-administered, online questionnaire-based study including mostly multiple choice questions concerning attitude and awareness regarding UCB banking was conducted entirely online among Facebook female users in Poland. A total of 1077 participants correctly completed the survey. Most participants (n = 911, 84.6%) were aware of the possibility of UCB banking. Social media were considered as the main source of information (47.5%). However, the participants mostly indicated the doctor as their preferred source of reliable information (86.8%). The majority of women (61.8%) assessed their level of knowledge of UCB banking as still insufficient. Among the participants who supported UCB banking (70%), the following reasons were considered as the most vital: potential possibility of helping their child (93.9%) and helping other relatives (64.4%). More than half of the respondents (66.9%), who have not stored and are not willing to store their children's UCB, indicated the high cost of UCB banking as the main reason of this decision. The knowledge and awareness of UCB storage and banking possibilities amongst women in Poland could be improved. The professional medical personnel should be a source of reliable information.

Stem cell preservation for regenerative therapies: ethical and governance considerations for the health care sector

The stem cell preservation industry has grown substantially with private businesses, public hospitals, and academic medical centers considering preserving induced pluripotent stem cells, mesenchymal stem cells, and other cell types of patients and the public in order to potentially use them for stem cell therapy should such an intervention exist in the future. Despite this growth and interest among private firms and academic centers, no study has yet considered the bioethical issues of such platforms. In this article, we explore several ethical and social issues related to the biopreservation of stem cells for future regenerative therapies. We analyze a range of bioethical considerations that public and private institutions should bear in mind as they develop stem cell preservation platforms. These include medical validation of regenerative interventions and their influence on the public understanding of stem cell therapies, the impact of public trust of organizations creating a private, for-profit venture of stem cell preservation, and logistical issues in the governance of the collection including ownership and dispositional authority, informed consent and access, and withdrawal and non-payment. These considerations should be incorporated into current and future stem cell preservation platforms in order to promote the responsible translation of regenerative medicine.

Identifying Barriers to Umbilical Cord Blood Banking in Jordan: A Cross-Sectional Survey of Obstetricians

Background: The expansion of umbilical cord blood (UCB) banking necessitates a greater understanding among obstetricians in order to responsibly inform parents about UCB collection and storage. Gaps in knowledge can compromise public UCB banking efforts and result in missed opportunities and public misguidance about UCB banking. Materials and Methods: A cross-sectional survey was disseminated among obstetricians in Amman, Jordan. The questionnaire aimed to evaluate obstetricians' knowledge of and attitude toward UCB storage and applications, as well as current practice patterns. Results: Ninety-six obstetricians responded (55% response rate), most of whom were Jordanian (71%), female (83%), resident physicians (59%), and working in either private (43%) or public (42%) hospitals, with an average of 6.5 years in practice. Only 26% had personal experience in UCB collection, and 20% had received education on UCB collection. Nearly 75% said their hospitals lacked standard operating procedures, guidelines, or infectious disease screening for UCB units. Overall knowledge about UCB was moderate, and the internet was the most common information source (54%). Overall attitudes were positive, especially in desire to expand personal knowledge about UCB, integrate information into medical residency curricula, and establish a public UCB bank in Jordan. However, many believed that ethical (61%) and religious (56%) controversies surround UCB donation. Conclusion: This study identifies deficiencies in quality control and experience in UCB collection in Jordan, as well as areas of inadequate knowledge and ethical controversies among obstetricians. These issues contribute to public misinformation and limit public UCB donation programs, and requires improved medical education on this topic.

Changes in Knowledge about Umbilical Cord Blood Banking and Genetic Tests among Pregnant Women from Polish Urban and Rural Areas between 2010-2012 and 2017

The aim of this study was to evaluate knowledge of umbilical cord blood (UBC) banking and prenatal genetic diagnosis among pregnant women from rural and urban areas, and how this knowledge changed within a five-year period. A survey by questionnaire was conducted between 2010 and 2012, and in 2017 in public hospitals; the study population comprised 6128 women, with 2797 patients from the years 2010-2012 and 3331 from the year 2017. 41% of the studied population declared that they were living in rural areas. In the 2010-2012 period, fewer women from rural areas knew about UBC banking. In 2017 that same relative difference in knowledge persisted, but the percentage of women who now knew about this procedure rose significantly in both studied groups. Prenatal diagnosis was more familiar for urban inhabitants both in 2010 and 2017 but as with the UBC data, a trend of growing awareness was also seen in pregnant women from rural areas. Knowledge of new techniques such as UBC banking and genetic tests has grown among pregnant women during the time frame of our study, but there is still a need to emphasize the benefits of these two possibilities to pregnant women, especially among rural inhabitants.

Maternity health professionals' perspectives of cord clamp timing, cord blood banking and cord blood donation: a qualitative study

Background

Parents today have several options for the management of their infant’s cord blood during the third stage of labour. Parents can choose to have their infant’s cord clamped early or to have deferred cord clamping. If the cord is clamped early, cord blood can be collected for private cord blood banking or public cord blood donation for use later if needed. If cord clamping is deferred, the placental blood physiologically transfuses to the neonate and there are physiological advantages to this. These benefits include a smoother cardiovascular transition and increased haemoglobin levels while not interfering with the practice of collecting cord blood for gases if needed. The aim of this study is to explore Australian maternity health professionals’ perspectives towards cord clamp timing, cord blood banking and cord blood donation.

Methods

Fourteen maternity health professionals (midwives and obstetricians) from both private and public practice settings in Australia participated in semi-structured interviews either in person or by telephone. Interviews were transcribed and data analysed using thematic analysis.

Results

Overall there was strong support for deferred cord clamping, and this was seen as important and routinely discussed with parents as part of antenatal care. However, support did not extend to the options of cord blood banking and donation and to routinely informing parents of these options even when these were available at their birthing location.

Conclusion

Formalised education for maternity health professionals is needed about the benefits and implications of cord blood banking and cord blood donation so that they have the confidence to openly discuss all options of cord clamp timing, cord blood banking and cord blood donation to facilitate informed decision-making by parents.

The law and problematic marketing by private umbilical cord blood banks

Background

Private umbilical cord blood banking is a for-profit industry in which parents pay to store blood for potential future use. Governments have noted the tendency for private banks to oversell the potential for cord blood use, especially in relation to speculative cell therapies not yet supported by clinical evidence. We assessed the regulatory landscape governing private cord bank marketing in Canada.

Main body

Because the problematic marketing of private cord blood banking for future use often relates to speculative future cell therapies that do not exist and are not being advertised for current clinical use, most private blood bank marketing seems to fall outside Health Canada’s regulatory scope. However, this problematic marketing is regulated by the Competition Bureau pursuant to the Competition Act. While representations relating to future hypothetical treatments may not always be subject to the legal requirement for claim substantiation, the law also prohibits individuals and companies from knowingly or recklessly making representations that are “false or misleading in a material respect.” A representation is materially false or misleading when it could “influence a consumer’s behavior or purchasing decisions,” and consumers are likely to be considered to be “credulous and inexperienced” for the purposes of assessing an advertisement’s general impression. Because all of the potential benefit of the banking is derived from the potential future use of the biological material for health interventions directed toward the customers and their relatives, and because we know the best available medical evidence indicates a very low probability of utility in this context, we can say with confidence that some private cord blood banking claims are materially misleading. Moreover, to the extent that medical professionals are involved in private bank interactions with customers or hold ownership stakes in private banks, they are subject to professional codes, standards of practice, and potentially fiduciary obligations that further prohibit misleading marketing.

Conclusions

Private cord blood bank marketing that advertises hypothetical future treatments can be misleading and may influence consumer behaviour. This marketing may breach existing advertising law. Regulatory bodies should enforce the law in order to help prevent public health and personal financial harm.

Knowledge and sources of information on umbilical cord blood donation in pregnant women

The use of umbilical cord blood (UCB) holds promise for the treatment of a wide spectrum of diseases. However, information on UCB donation is not widespread or accurate among expectant women. The aim of this study is to evaluate pregnant women's knowledge of UCB donation, their main sources of information and their satisfaction with the knowledge possessed. Women (N = 375) in the last semester of pregnancy completed questionnaires evaluating sociodemographics, knowledge of UCB donation, past donation, sources of information, satisfaction with the information and the desire to have received more information. Women were aware of the possibility of donating UCB (97.5%) although, on average, they reported not having enough knowledge of donation possibilities, procedures to be followed and uses of UCB (2.51, on a 5-point scale). Considering knowledge satisfaction, 28% were not at all satisfied. Only 2.8% felt fully prepared and the great majority (75.2%) would have liked to have received more information. The main source of information was the Internet (51.2%). Gynecologists and midwives were indicated by only 24.4% and 18.6% of women, respectively. Age and education were significantly correlated with UCB knowledge. Chi-square tests evidenced that those who reported professional sources of information (gynecologists, obstetricians, prenatal courses) did not need additional information. Conversely, mothers who turned to other mothers for information were more likely to desire further information. Most mothers report the Internet as the main source of information. Providing accurate information through official sources may result in a more positive attitude toward donation.

Exploring the relationship between umbilical blood cord donation and the impact of social distance on altruism and trust

Allogeneic umbilical cord blood (UCB) donation is a pro-social behaviour directed to strangers that has a certain cost for the donor. Although the promotion of such behaviour is an important goal for many countries' health systems, little is known about the reasons that would lead to it. With this study, we explored how the impact of social closeness on altruism and trust could be related to UCB donation in a sample of new-mothers (N = 167). Participants played hypothetical Dictator and Trust games with socially close (e.g., parents) or distant (e.g., strangers) others. They donated more money to parents and siblings compared to cousins, friends and strangers and they trusted more parents, siblings and friends than cousins and strangers. Interestingly, the lower the impact of social closeness on altruism (i.e., generosity towards socially distant others), the higher the intention and the actual probability of UCB donation. A mediation analysis has shown that the relationship between social closeness on altruism and UCB donation was mediated by objective intention to donate (i.e., having followed all the procedures needed). These findings show that other-oriented motivations towards distant others might have important practical implications in identifying the targets of interventions for the promotion of UCB donation.

Knowledge and Attitude Among Lebanese Pregnant Women Toward Cord Blood Stem Cell Storage and Donation

Background: Umbilical cord blood (UCB) used to be considered waste material and was discarded at birth. However, cord blood is now considered a rich source of adult stem cells that can be used to treat many conditions and diseases. This study was performed to determine pregnant women's knowledge and attitudes toward cord blood stem cell banking and donation in Lebanon. Methods: A descriptive study was conducted in antenatal clinics in Beirut and data were collected using a questionnaire distributed to pregnant women after provision of informed consent. A total of 244 women responded. Results: Less than half of the women (46%) reported knowledge about cord blood banking. However, participants with university and secondary education had significantly higher odds of considering UCB storage compared to those with primary education (odds ratio (OR) 8.62, 95% confidence interval (CI) 2.74-27.15 and OR 21.23,95% CI 6.55-68.86, respectively). Older pregnant women were less likely to think about UCB stem cells storage (OR 0.92, 95% CI 0.85-0.98). Conclusion: Respondents who had an existing knowledge about UCB stem cells banking in general were more likely to consider storing UCB in blood banks if affordable (45.9%). Therefore, it is necessary to inform pregnant women about stem cell banking so that they can make the appropriate decisions for themselves.
