Bone marrow donation in Poland: 2021 update, and the impact of the coronavirus disease 2019 pandemic on haematopoietic stem cell transplantation

Raising awareness may increase the likelihood of hematopoietic stem cell donation: a nationwide survey using artificial intelligence

BACKGROUND

In Italy, the demand for allogeneic transplantation exceeds the number of compatible donors in the Italian Bone Marrow Donor Registry (IBMDR). This study aimed to explore the knowledge, beliefs, opinions, values, and feelings of the Italian population regarding stem cell donation.

METHODS

An online survey was shared via social media. Respondents were retrospectively identified as registered on the IBMDR (donor group) or never registered (non-donor group). Statistical analyses confirmed the relationship between knowledge level and willingness to donate. Six machine learning classifiers were trained using questionnaire responses to predict the probability of IBMDR registration.

RESULTS

A total of 1518 respondents participated. Characteristics identified in the non-donor group were a lower level of knowledge regarding donation needs (51.7% vs 24.4%, p < 0.001) and negative feelings such as fear (Z = - 2.2642, p = 0.02), confusion (Z = 4.4821, p < 0.001), and uncertainty (Z = 3.3425, p < 0.001). Higher knowledge predicted a greater likelihood of IBMDR enrollment. Machine learning analysis showed an AUC ranging from 0.65 to 0.81, depending on the classifier.

CONCLUSIONS

The results underscore the need to improve strategies to raise awareness and knowledge of stem cell donation among the Italian population.

'Be the Match'. Predictors of Decisions Concerning Registration as a Potential Bone Marrow Donor-A Psycho-Socio-Demographic Study

(1) Background: The study was aimed at a better understanding of the factors determining making a decision to become a potential bone marrow donor, in a Polish research sample; (2) Methods: The data was collected using a self-report questionnaire among persons who voluntarily participated in the study concerning donation, conducted on a sample of the Polish population via Internet. The study included 533 respondents (345 females and 188 males), aged 18-49. Relationships between the decision about registration as potential bone marrow donor and psycho-socio-demographic factors were estimated using the machine learning methods (binary logistic regression and classification & regression tree); (3) Results. The applied methods coherently emphasized the crucial role of personal experiences in making the decision about willingness for potential donation, f.e. familiarity with the potential donor. They also indicated religious issues and negative health state assessment as main decision-making destimulators; (4) Conclusions. The results of the study may contribute to an increase in the effectiveness of recruitment actions by more precise personalization of popularizing-recruitment actions addressed to the potential donors. It was found that selected machine learning methods are interesting set of analyses, increasing the prognostic accuracy and quality of the proposed model.

Secondary Impact of the Coronavirus Disease 19 Pandemic on Patients and the Cellular Therapy Healthcare Ecosystem

The Coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has significantly impacted global health and healthcare delivery systems. To characterize the secondary effects of the COVID-19 pandemic and mitigation strategies used in the delivery of hematopoietic stem cell transplantation (HSCT) care, we performed a comprehensive literature search encompassing changes in specific donor collection, processing practices, patient outcomes, and patient-related concerns specific to HSCT and HSCT-related healthcare delivery. In this review, we summarize the available literature on the secondary impacts the COVID-19 pandemic on the fields of HSCT and cellular therapy. The COVID-19 pandemic has had numerous secondary impacts on patients undergoing HSCT and the healthcare delivery systems involved in providing complex care to HSCT recipients. Institutions must identify these influences on outcomes and adjust accordingly to maintain and improve outcomes for the transplantation and cellular therapy community.

Secondary Oral Cancer after Systemic Treatment of Hematological Malignancies and Oral GVHD: A Systematic Review

(1) Purpose: In this article, the authors decided to systematically review the available literature to identify potential correlations regarding secondary oral carcinoma occurring after hematological systemic treatment and oral chronic graft-versus-host disease. (2) Methods: Medline (PubMed) and Scopus (Elsevier) databases were searched, including articles from the years 2002-2022. The 33 unique results were assessed by a PRISMA flowchart, and we rejected 24 papers and included 9 articles in the review. (3) Results: The majority of patients suffered from the oral form of chronic graft-versus-host disease before the diagnosis of oral malignancy. Two common cancer sites were the tongue and buccal mucosa. The exact percentage of secondary oral carcinoma after hematopoietic stem cell transplantation could not be estimated due to a lack of data. (4) Conclusions: Every physician taking part in the follow-up of patients after hematological treatment should be aware of the possibility of secondary neoplastic disease in the oral cavity, especially in patients with oral graft-versus-host disease. Proper follow-up protocols and monitoring are needed in this patient group as the cause of these cancers appears to be multifactorial.

Awareness and Acceptance of Hematopoietic Stem Cell Transplantation for Sickle Cell Disease in Jazan Province, Saudi Arabia

BACKGROUND

Sickle cell diseases (SCD) are a group of inherited disorders that lead to abnormal beta subunits of hemoglobin (Hb) and are characterized by several complications which can be life-threatening. The prevalence of this disease is high in Jazan province, Saudi Arabia. The current protocol for the treatment of SCD is mainly based on alleviating signs and symptoms to avoid severe complications. Hematopoietic stem cell transplant (HSCT) is considered a definitive therapy for SCD. However, there is a long patient waiting list for HSCT in Saudi Arabia. A lack of community awareness and incorrect information about the importance of HSCT in SCD treatment is believed to be contributing to the shortage in HSCT. Thus, this study aims to assess community awareness and attitudes toward HSCT as a cure for SCD in Jazan province, Saudi Arabia.

METHODS

An observational cross-sectional retrospective study was conducted in Jazan province. General and demographic data were collected and pretested survey including questions about public knowledge and attitude toward HSCT for SCD were answered. Both t-test and chi-square tests were used for analysis.

RESULTS

1167 participants were included in this study with a mean age of 26 (SD: 8). About 50% of the study participants believed that SCD can be treated and 78% of the study participants already have heard about HSCT. About 57% of the participants defined HSCT correctly and 42% were willing to donate. Better knowledge and positive attitude toward HSCT were significantly reported among patients with SCD or their relatives as well as among people with higher education and healthcare workers (HCW).

CONCLUSION

About 57% of the study participants were able to define HSCT and most related questions were answered correctly. A positive correlation was found between the knowledge about HSCT and people with higher education or those who were diagnosed with SCD or their relatives and friends. Further, only 42% of our study participants were willing to donate, a percent that is positively associated with better knowledge about HSCT. National education programs are needed to enhance the overall awareness of Jazan communities toward HSCT which could contribute to reducing the number of patients waiting for HSCT.
