Bioengineering (Basel) 2024; 11:124. [PMID: 38391610 PMCID: PMC10886122 DOI: 10.3390/bioengineering11020124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 01/17/2024] [Accepted: 01/24/2024] [Indexed: 02/24/2024] Open
Abstract
Accelerated brain aging (ABA) intricately links with age-associated neurodegenerative and neuropsychiatric diseases, emphasizing the critical need for a nuanced exploration of heterogeneous ABA patterns. This investigation leveraged data from the UK Biobank (UKB) for a comprehensive analysis, utilizing structural magnetic resonance imaging (sMRI), diffusion magnetic resonance imaging (dMRI), and resting-state functional magnetic resonance imaging (rsfMRI) from 31,621 participants. Pre-processing employed tools from the FMRIB Software Library (FSL, version 5.0.10), FreeSurfer, DTIFIT, and MELODIC, seamlessly integrated into the UKB imaging processing pipeline. The Lasso algorithm was employed for brain-age prediction, utilizing derived phenotypes obtained from brain imaging data. Subpopulations of accelerated brain aging (ABA) and resilient brain aging (RBA) were delineated based on the error between actual age and predicted brain age. The ABA subgroup comprised 1949 subjects (experimental group), while the RBA subgroup comprised 3203 subjects (control group). Semi-supervised heterogeneity through discriminant analysis (HYDRA) refined and characterized the ABA subgroups based on distinctive neuroimaging features. HYDRA systematically stratified ABA subjects into three subtypes: SubGroup 2 exhibited extensive gray-matter atrophy, distinctive white-matter patterns, and unique connectivity features, displaying lower cognitive performance; SubGroup 3 demonstrated minimal atrophy, superior cognitive performance, and higher physical activity; and SubGroup 1 occupied an intermediate position. This investigation underscores pronounced structural and functional heterogeneity in ABA, revealing three subtypes and paving the way for personalized neuroprotective treatments for age-related neurological, neuropsychiatric, and neurodegenerative diseases.

Abstract
Background: To integrate biobanks into the Moroccan health system and to promote biobanks-based research projects, it is necessary to explore the knowledge of patients, their attitudes toward biobanks, and the reasons that motivate them to participate in biobanks. Methods: Face-to-face interviews were conducted with patients, and data were analyzed using SPSS. Results: One thousand one hundred thirty-three questionnaires were completed. The mean age of patients was 47.74 years (SD 15.26 years). More women (69%) were involved in this survey. Of the respondents, 97% had never heard of the term "biobanks." Knowledge of biobanks varied significantly with respondents' education level. Overall, 80.7% of the participants (n = 914) expressed their willingness to participate in biobanking through donation of biospecimens associated with personnel and health data. Willingness to participate in biobanks was significantly associated with gender and age. We found that the main barriers to participation in biobanks were the lack of trust in biomedical research and concerns about privacy. When asked about the preferred type of consent, the majority of patients (75%) opted for a one-time consent. Conclusion: Despite the lack of knowledge of biobanks among patients in Eastern Morocco, the majority of them expressed willingness to participate in biobanking through donation of biospecimens. However, active participation depended upon a number of factors, notably, the trust in biomedical research and privacy. Therefore, more efforts are needed to increase awareness and promote wider participation in biobanking.

Abstract
PURPOSE Recruitment of adequate numbers of research participants is important for advancement in biomedical fields. Awareness and knowledge of the population about biomedical research are expected to enhance willingness to participate in such research. Therefore, in the current study, participants' awareness, knowledge, and willingness to participate in scientific research in Jordan were examined. METHODS This was a survey-based, cross-sectional study conducted from December 2019 to February 2020 among the public in Jordan. After written informed consent had been obtained from study participants, a structured questionnaire was used to survey research participants. The final questionnaire contained three parts: part I was about demographics and general information, part II assessed participants' awareness and willingness to participate in biomedical research, and part III assessed participants' knowledge about biomedical research studies. RESULTS A total of 2,000 subjects agreed to participate, of which 67.4% were female (n=1339). More than half the respondents were aware of biomedical research (58.6%), of which 18.1% had previously participated in biomedical research. In addition, 55.5% reported that they were willing to participate in biomedical research, while a lower proportion (31.1%) were willing to volunteer in a clinical trial. The overall knowledge of participants about biomedical research was deemed moderate (total score 12.9 out of 20). Finally, willingness to participate in biomedical research was associated with being male, being married, having a biomedicine-related degree, and higher knowledge score. CONCLUSION A majority of Jordanians had moderate levels of awareness and knowledge about biomedical research. Such factors as sex, type of education, and knowledge contribute to willingness to participate in biomedical research.

Abstract
The Italian Twin Registry (ITR), established in 2001, is a population-based registry of voluntary twins. To date, it consists of approximately 29,000 twins who gave their consent to participate in the studies proposed by the ITR research group. The database comprises 11,500 monozygotic and 16,700 dizygotic twins resident throughout the country and belonging to a wide age range (from 0 to 95 years, mean 36.8 years). This article provides an overview of the recruitment strategies along with the major phenotypes investigated during an 18 years' research period. Over the years, several self-reported questionnaire data were collected, together with saliva/blood samples and measurements taken during in-person interviews or outpatient clinical examinations. Mental and behavioral phenotypes as well as atherosclerotic traits were studied in depth across different age groups. A birth cohort of twins was established and followed up. Novel research hypotheses are also being tested in ongoing projects. The ITR is involved in international studies in collaboration with other twin registries and represents a valuable resource for national and international research initiatives regarding a broad spectrum of health-related characteristics.

Abstract
Observational genome-wide association studies require large sample sizes. Evaluating the interplay between genomic, environmental, and lifestyle factors can require even larger sample sizes. The All of Us Research Program will recruit 1 million participants to facilitate research on genomic, environmental, and lifestyle factors. Integrating participant preferences into the research process is a new paradigm and a necessary component of the All of Us Research Program. The purpose of the study is to summarize quantitative studies of participant preferences related to participation in observational genomic research studies, starting with consent through return of results. Integrating this information into the conduct of genomic studies may benefit participants, and improve participant satisfaction, recruitment, and retention. We conducted a systematic review of the literature regarding participant views related to reconsent and broad consent, use of de-identified data, contribution of data to a biorepository, risk of identification, return of individual genetic results, and motivation for participation in genomic studies. Twenty-three articles met our inclusion and exclusion criteria. Study results found that most participants support broad consent; however, significant differences related to reconsent preferences have been shown by gender and age. Most participants support the return of individual genomic results and do not feel it is necessary to maintain a link to their de-identified data. Reasons given for joining research studies varied by population source. These findings, in addition to the knowledge that participants are more accepting of broad informed consent methods when the rationale is explained, can assist in developing guidelines for future observational genomic research.
