Abstract
AIM Participant recruitment has always been a major challenge in clinical trials. This study aimed to develop and validate the Join Clinical Trial Questionnaire (JoinCT), exploring the willingness to join a clinical trial and associated factors in patients. METHODS This questionnaire development study involved four phases: (i) exploring and understanding the subject matter, (ii) questionnaire development, (iii) content validity testing, and lastly, (iv) field-testing of the questionnaire. For the field-testing phase, a cross-sectional self-administered survey of JoinCT was conducted among cancer patients with various socio-demographic backgrounds and medical conditions. Besides content validity, Cronbach's alpha was used to evaluate the internal consistency of domains, and confirmatory factor analysis was used to evaluate the model fit of the JoinCT framework. RESULTS A total of 389 respondents participated in the survey. Based on the results obtained from a field data collection phase, JoinCT consisted of four independent variables domains, namely "knowledge", "perception of benefits", "perception of risks", and "confidence". The only dependent variable was the willingness to participate in a clinical trial. The minimum Cronbach's alpha was 0.937, and the model fit for the overall framework of JoinCT is also excellent with Comparative Fit Index (> 0.90), root mean square error approximation (< 0.08), and Standardized Root Mean Square Residual (< 0.08). CONCLUSIONS The Join Clinical Trial Questionnaire (JoinCT) was successfully validated with excellent reliability and validity, and a good model fit. The main factors that contribute to willingness to participate in clinical trials are knowledge, perception of benefits, perception of risks, and confidence.

Abstract
BACKGROUND Personalized medicine is an emerging field, aiming to improve the safety and efficacy of pharmacotherapy. The field's implementation in clinical care is steadily increasing. Pharmacogenomics are one example of personalized approaches in the clinic and direct-to-consumer (DTC) pharmacogenomic tests have become publicly available. We aimed to assess public opinion on pharmacogenomic research and testing to foster integration within Belgian health care. METHODS A cross-sectional survey was created and disseminated online, focusing on the citizen perspective. Participants' willingness to engage in pharmacogenomic research was the primary outcome. In addition, their awareness, understanding, expectations and overall acceptance towards pharmacogenomic testing was investigated. RESULTS A total of 156 participants (54.5% aged between 18 and 30 years, 45.5% > 30 years; 73.1% females) completed the survey. Half ever experienced side effects (46.2%) and treatment failure (52.6%). Up to 45.5% (n = 71) were willing to participate in pharmacogenomics research, and the majority (78.8%) were convinced that pharmacogenomic tests could help doctors to prescribe them the right medications. Additionally, 76.3% (n = 118) supported a partial reimbursement of pharmacogenomics tests. A minority (5.1%, n = 8) of participants showed interest in DTC tests, and 15.4% (n = 24) expressed privacy concerns regarding pharmacogenomics testing. Participants preferred their healthcare professionals' to perform the test and access their data, but refused commercial providers. CONCLUSION Overall, participants showed a positive attitude towards precision medicine and pharmacogenomics research. Our findings may help guiding future pharmacogenomic implementation initiatives to optimize drug use by using pharmacogenomic information integrated within health care.

Abstract
This secondary analysis examined (1) factors associated with willingness to participate in clinical research for cognitive health among individuals with cognitive impairment and their care partners, and (2) concordance regarding such willingness between individuals with cognitive impairment and their care partners (dyads). Neuropsychological factors and willingness to participate in clinical research were collected using self-reported questionnaires. Participants' sociodemographic and clinical information was extracted from the University of Pittsburgh Alzheimer's Disease Research Center record. Binary logistic regression and Cohen's kappa coefficient analyses were performed. Greater trust in medical researchers (p = 0.031, B = 0.127) and more severe cognitive impairment (p = 0.009, B = -0.289) were associated with willingness to participate in clinical research among individuals with cognitive impairment. Dyadic agreement on willingness to have the individual with cognitive impairment enroll in clinical research was poor to fair (κ = 0.380). Findings suggest that individuals with cognitive impairment with greater trust in health professionals are more likely to agree to clinical research participation. Nurses and other health care providers who counsel individuals with cognitive impairment and their care partners should work to build trusting relationships with participants and be mindful of how increased trust can alter power dynamics between participants and health care professionals.

Abstract
Background The increasing number of clinical research opportunities requires increasing numbers of participants in clinical trials. However, it may become increasingly problematic, as protocols have become increasingly complex. Better understanding of patients’ attitudes towards their potential participation in clinical trials is essential for developing effective clinical trial recruitment strategies. In Greece, limited research has been conducted on this topic so far. This study aims to contribute to filling this gap. Methods A cross-sectional study was conducted. Purposive sampling was used to select participants. The Greek version of a recently developed questionnaire measuring patient views on participation in clinical trials, a 27-item scale distributed into four factors, was tested. In addition, participants were asked to provide information regarding their socio-demographics. A demographic comparison was conducted. Results The four-factor solution derived in our study consisted of the same 27 items and it was different from the six-factor solution that Arnetz et al. proposed. The factors risks and benefits, that consisted of 5 and 3 items respectively in the six-factor solution, were merged into one factor that consisted of 10 items in the four-factor solution. The four factors produced were Risks and benefits (ten items, α = 0,867), Patient’s expectations (six items, α = 0.864), Patient’s participation (five items, α = 0.827), and Cost and convenience (five items, α = 0,770). We found that demographic factors did not impact patients’ opinions about clinical trials participation, except for gender. The participants reported as important for participating in clinical trial: receiving clear and adequate information (95,5 %) and being given the opportunity to ask questions (97,8 %), take part in discussions regarding their own treatment (94,6 %), and voice their concerns and opinions (91,1 %). As factors strongly associated with participants’ willingness to participate in a clinical trial were reported: concerns about the risks of being in a clinical trial (87,5 %), the possible side effects of clinical trials (86,3 %), the type of treatment given in a clinical trial (83,7 %), and whether participation would improve their quality of life (QoL) (81,5 %). Conclusions The preliminary validation of the Greek version of the questionnaire measuring patient perceptions and expectations of participating in clinical trials demonstrated acceptable validity and reliability and could be further tested in larger samples. The findings that emerged from this study are in line with previous literature. Supplementary Information The online version contains supplementary material available at 10.1186/s12913-021-07111-x.

Abstract
PURPOSE We examined prostate cancer patients' participation in research and associated factors by race/ethnicity in a multiethnic sample. METHODS Men with a new diagnosis of prostate cancer were identified through the California Cancer Registry. Patients completed a cross-sectional telephone interview in English, Spanish, Cantonese or Mandarin. Multivariable logistic regression models, stratified by race/ethnicity, estimated the associations of patient demographic and health characteristics with participation in (1) any research, (2) behavioral research, and (3) biological/clinical research. RESULTS We included 855 prostate cancer patients: African American (19%), Asian American (15%), Latino (24%), and White (42%). In the overall model of participation in any research, African American men (Odds Ratio (OR) = 2.54, 95% CI 1.63-3.94), and those with two or more comorbidities (OR = 2.20, 95% CI 1.27-3.80) were more likely to report participation. Men 65 years old and older (OR = 0.65, 95% CI 0.47-0.91), those who were married or living with a partner (OR = 0.67, 95% CI 0.45-0.98), and those who completed the interview in Spanish (OR = 0.36, 95% CI 0.15-0.85) were less likely to report participating in any research. Stratified analyses identified racial/ethnic-specific sociodemographic characteristics associated with lower research participation, including Spanish or Chinese language, older age, and lower education. CONCLUSION African American prostate cancer patients reported higher research participation than all other groups. However, recruitment efforts are still needed to overcome barriers to participation for Spanish and Chinese speakers, and barriers among older adults and those with lower education levels.

JOURNAL OF MEDICAL ETHICS 2020; 46:678-684.

Abstract
Recent calls for retraction of a large body of Chinese transplant research and of Dr Jiankui He's gene editing research has led to renewed interest in the question of publication, retraction and use of unethical biomedical research. In Part 1 of this paper, we briefly review the now well-established consequentialist and deontological arguments for and against the use of unethical research. We argue that, while there are potentially compelling justifications for use under some circumstances, these justifications fail when unethical practices are ongoing-as in the case of research involving transplantations in which organs have been procured unethically from executed prisoners. Use of such research displays a lack of respect and concern for the victims and undermines efforts to deter unethical practices. Such use also creates moral taint and renders those who use the research complicit in continuing harm. In Part 2, we distinguish three dimensions of 'non-use' of unethical research: non-use of published unethical research, non-publication, and retraction and argue that all three types of non-use should be upheld in the case of Chinese transplant research. Publishers have responsibilities to not publish contemporary unethical biomedical research, and where this has occurred, to retract publications. Failure to retract the papers implicitly condones the research, while uptake of the research through citations rewards researchers and ongoing circulation of the data in the literature facilitates subsequent use by researchers, policymakers and clinicians.

Abstract
Objective: Human participants play an important role in medical care advances. Recruiting enough participants is perhaps the most significant procedure that determines the success of medical research, and high participation rate brings about many benefits. Therefore, acquiring enough participants is important for medical researchers. To understand how to improve participation rate, we need to clarify factors affecting the public's attitude toward medical research. Through this review, we aim to examine which factors affect the attitude of human participants toward medical research.Methods: The relevant data were searched by using the keywords "Public," "Participants," "Medical" and "Research" in PubMed (MEDLINE), International Pharmaceutical Abstracts, Web of Science, Science Direct, CINAHL Plus, EMBASE, and China Knowledge Resource Integrated databases. A manual search was done to acquire peer-reviewed articles and reports about participation in medical research.Results: Sixty-three studies were identified for inclusion after full text screening. The included studies were of variable quality. Some factors affecting people's attitude toward participating in medical research have been identified and discussed in our review.Conclusion: This review demonstrated that willingness of participants to take part in medical research was influenced by a variety of factors. These factors may be used to predict the public's willingness to take part in medical research and may potentially be used in developing strategies aimed at improving participation rate.

Abstract
Digital technologies such as smartphones are transforming the way scientists conduct biomedical research. Several remotely conducted studies have recruited thousands of participants over a span of a few months allowing researchers to collect real-world data at scale and at a fraction of the cost of traditional research. Unfortunately, remote studies have been hampered by substantial participant attrition, calling into question the representativeness of the collected data including generalizability of outcomes. We report the findings regarding recruitment and retention from eight remote digital health studies conducted between 2014-2019 that provided individual-level study-app usage data from more than 100,000 participants completing nearly 3.5 million remote health evaluations over cumulative participation of 850,000 days. Median participant retention across eight studies varied widely from 2-26 days (median across all studies = 5.5 days). Survival analysis revealed several factors significantly associated with increase in participant retention time, including (i) referral by a clinician to the study (increase of 40 days in median retention time); (ii) compensation for participation (increase of 22 days, 1 study); (iii) having the clinical condition of interest in the study (increase of 7 days compared with controls); and (iv) older age (increase of 4 days). Additionally, four distinct patterns of daily app usage behavior were identified by unsupervised clustering, which were also associated with participant demographics. Most studies were not able to recruit a sample that was representative of the race/ethnicity or geographical diversity of the US. Together these findings can help inform recruitment and retention strategies to enable equitable participation of populations in future digital health research.

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
Drug lag, which delays patients' access to medicinal products, is typically associated with pharmaceutical regulations. To shorten drug lag, health authorities may establish new policies to liberalize the regulations, a step that is important in countries, such as Taiwan, with consumer demand for imported novel therapeutic agents. Taiwan's government enacted Articles 38-1 and 38-2 of Regulations for Registration of Medicinal Products to relax the regulatory barriers for new drug submission, thus conditionally exempting the requirement for the Certificate of Pharmaceutical Product (CPP). This study examined whether the enacted regulations reduce submission lag by analyzing the time gap of submission between Taiwan and the United States during 2014-2017. The results indicated that the enacted regulations substantially affected submission lag. Submission lag was significantly shorter for applications not requiring a CPP than those requiring one CPP, which in turn was significantly shorter than those requiring two CPPs. This conclusion can be applied to biological, chemical, non-orphan, and oncology drugs and also applications filed by subsidiary companies, but not orphan drugs and applications filed by contract agents. Among applications requiring one CPP, oncology drugs showed the shortest submission lag. Certain factors, such as clinical studies recruiting over-threshold Taiwanese participants and those performed before the submission of new drug application in the United States, may shorten submission lag. In summary, this study justifies the policy of the exemption from CPP requirements, which supports the hypothesis that relaxing regulatory barriers can reduce submission lag in Taiwan.
