Abstract
Bone, a fundamental constituent of the human body, is a vital scaffold for support, protection, and locomotion, underscoring its pivotal role in maintaining skeletal integrity and overall functionality. However, factors such as trauma, disease, or aging can compromise bone structure, necessitating effective strategies for regeneration. Traditional approaches often lack biomimetic environments conducive to efficient tissue repair. Nanofibrous microspheres (NFMS) present a promising biomimetic platform for bone regeneration by mimicking the native extracellular matrix architecture. Through optimized fabrication techniques and the incorporation of active biomolecular components, NFMS can precisely replicate the nanostructure and biochemical cues essential for osteogenesis promotion. Furthermore, NFMS exhibit versatile properties, including tunable morphology, mechanical strength, and controlled release kinetics, augmenting their suitability for tailored bone tissue engineering applications. NFMS enhance cell recruitment, attachment, and proliferation, while promoting osteogenic differentiation and mineralization, thereby accelerating bone healing. This review highlights the pivotal role of NFMS in bone tissue engineering, elucidating their design principles and key attributes. By examining recent preclinical applications, we assess their current clinical status and discuss critical considerations for potential clinical translation. This review offers crucial insights for researchers at the intersection of biomaterials and tissue engineering, highlighting developments in this expanding field.

Three-dimensional spatial analysis of temporomandibular joint in adolescent Class II division 1 malocclusion patients: comparison of Twin-Block and clear functional aligner. Head Face Med 2024; 20:4. [PMID: 38184631 PMCID: PMC10770962 DOI: 10.1186/s13005-023-00404-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 12/18/2023] [Indexed: 01/08/2024] Open
Abstract
BACKGROUND Our study aimed to use three-dimensional (3D) spatial morphological measurement methods to compare the influence of Twin-Block and clear functional aligners on the temporomandibular joint (TMJ) of adolescent Class II division 1 malocclusion mandibular retraction patients. We also aimed to explore the similarities and differences in the effects on the TMJ upon using Twin-Block and clear functional aligner. METHODS Cone-beam computed tomography (CBCT) data of 49 patients with Class II division 1 malocclusion (Twin-Block group: 24; clear functional aligner group: 25) were collected before and after functional orthodontic treatment, and a 3D model of the TMJ was reconstructed using MIMICS 21.0 software. Eighteen measurement parameters, including the anterior, superior, and posterior joint spaces, were measured and compared using the 3D model. RESULTS After the two groups underwent functional appliance treatment, the height, volume, and surface area of the condyle, length of the mandibular ramus and mandibular length increased; The retro-displaced condyle moved to the middle position of the articular fossa, while the rest of the condylar position did not change significantly. Remodeling of the articular fossa after treatment was not evident. The superior joint space of the clear functional aligner group increased, but there was no significant change after Twin-Block appliances treatment. CONCLUSIONS Both appliances promote condylar growth and sagittal and vertical development of the mandible in adolescent Class II division 1 malocclusion mandibular retraction patients. The length of the mandibular ramus showed a more significant increase following treatment with the Twin-Block appliances than with clear function aligners.

Exploring the Decision-Making Process of People Living with HIV Enrolled in Antiretroviral Clinical Trials: A Qualitative Study of Decisions Guided by Trust and Emotions. HEALTH CARE ANALYSIS 2023; 31:135-155.

Abstract
The informed consent is an ethical and legal requirement for potential participants to enroll in a study. There is ample of evidence that understanding consent information and enrollment is challenging for participants in clinical trials. On the other hand, the reasoning process behind decision-making in HIV clinical trials remains mostly unexplored. This study aims to examine the decision-making process of people living with HIV currently participating in antiretroviral clinical trials and their understanding of informed consent. We conducted a qualitative socio-constructivist study using semi-structured interviews. Eleven participants were selected by purposive sampling in Argentina until data saturation was reached. A content analysis was performed. The findings highlight the fact that some participants decided to enroll on the spot, while others made the decision a few days later. In all cases, the decision was based on different aspects of trust (in doctors, in the clinical research site, in the clinical trials system) but also on emotions associated with HIV and/or treatment. Moreover, while people living with HIV felt truly informed after the consent dialogue with a researcher, consent forms were unintelligible and unfriendly. The immediacy of patient decision-making has rarely been described before. Enrollment in an HIV clinical trial is mainly a trust-based decision but this does not contradict the ethical values of autonomy, voluntariness, non-manipulation, and non-exploitation. Thus, trust is a key issue to be included in reshaping professional practices to ensure the integrity of the informed consent process.

Abstract
Qualitative data sharing practices in psychology have not developed as rapidly as those in parallel quantitative domains. This is often explained by numerous epistemological, ethical and pragmatic issues concerning qualitative data types. In this article, I provide an alternative to the frequently expressed, often reasonable, concerns regarding the sharing of qualitative human data by highlighting three advantages of qualitative data sharing. I argue that sharing qualitative human data is not by default 'less ethical', 'riskier' and 'impractical' compared with quantitative data sharing, but in some cases more ethical, less risky and easier to manage for sharing because (1) informed consent can be discussed, negotiated and validated; (2) the shared data can be curated by special means; and (3) the privacy risks are mainly local instead of global. I hope this alternative perspective further encourages qualitative psychologists to share their data when it is epistemologically, ethically and pragmatically possible.

Abstract
Informed consent (IC) is the process of communication between research staff and potential research participants. However, ensuring that participants clearly understand what research participation entails, raises significant challenges. The aim of this study is to provide insight into some communication barriers that research staff are confronted with and make practical recommendations to improve communication between research staff and participants. A qualitative research study using semi-structured interviews (n = 13) with research staff from Ghent University Hospital was conducted. Data were transcribed verbatim and coded thematically. Our results indicate that communication- and process-related factors affect the IC process. Emergent recommendations include communication training, more interactive information materials and the use of digital alternatives, increasing general knowledge about research participation and patient- and public involvement.

Abstract
Biobanks act as the custodians for the access to and responsible use of human biological samples and related data that have been generously donated by individuals to serve the public interest and scientific advances in the health research realm. Risk assessment has become a daily practice for biobanks and has been discussed from different perspectives. This paper aims to provide a literature review on risk assessment in order to put together a comprehensive typology of diverse risks biobanks could potentially face. Methodologically set as a typology, the conceptual approach used in this paper is based on the interdisciplinary analysis of scientific literature, the relevant ethical and legal instruments and practices in biobanking to identify how risks are assessed, considered and mitigated. Through an interdisciplinary mapping exercise, we have produced a typology of potential risks in biobanking, taking into consideration the perspectives of different stakeholders, such as institutional actors and publics, including participants and representative organizations. With this approach, we have identified the following risk types: economic, infrastructural, institutional, research community risks and participant's risks. The paper concludes by highlighting the necessity of an adaptive risk governance as an integral part of good governance in biobanking. In this regard, it contributes to sustainability in biobanking by assisting in the design of relevant risk management practices, where they are not already in place or require an update. The typology is intended to be useful from the early stages of establishing such a complex and multileveled biomedical infrastructure as well as to provide a catalogue of risks for improving the risk management practices already in place.

Abstract
Consent is one necessary foundation for ethical research and it’s one of the research ethics committee’s major roles to ensure that the consent process meets acceptable standards. Although on Oxford ‘A’ REC (an NHS Research Ethics Committee based in the UK) we’ve been impressed by the thought and work put into this aspect of research ethics, we’ve continued to have concerns about the suitability and effectiveness of consent processes in supporting decision making, particularly for clinical trials. There’s poor understanding of what people want to help them decide; current processes don’t provide the best grounding for informed consent and there’s inadequate public involvement. We’ve also found a lack of proportionality with researchers failing to adapt consent procedures in proportion to the burdens and consequences of the study. As a result, people are often not best helped to make an informed choice when asked to join a research study. To address these concerns, we considered how we might improve this aspect of research ethics review. Recognising the central importance of the dialogue between the volunteer and researcher, we’ve drawn up a model or flowchart of what we deem good consent practice, proposing consent should be built around four simple steps: Step 1: Introducing the study and the choices: helping the potential participants get an overview of the proposal and introducing the key issues. Step 2: Explaining all the details of the study using the detailed Participant Information Sheet. Step 3: After a gap, if necessary, reviewing and checking understanding. Step 4: Reaching agreement and recording consent. These steps, we believe, could help all involved and this article lays out ways we might improve participant choice while complying with accepted principles and current regulations.

Abstract
Background Biomedical research nowadays is increasingly carried out in multinational and multicenter settings. Due to disparate national regulations on various ethical aspects, such as informed consent, there is the risk of ethical compromises when involving human subjects in research. Although the Declaration of Helsinki is the point of reference for ethical conduct of research on humans, national normative requirements may diverge from its provisions. The aim of this research is to examine requirements on informed consent in biomedical research in Germany, Poland, and Russia to determine how each national regulatory framework relates to the provisions of the Declaration of Helsinki. Methods For this analysis, we conducted a search of the legal databases “Gesetze im Internet” for Germany, “Internetowy System Aktow Prawnych” for Poland, and “ГAPAHT – Garant” for Russia. The search was complemented by a review of secondary literature contained in the databases Google Scholar, PubMed, Polish National Library, and eLibrary.ru. We have identified 21 normative regulations containing provisions on informed consent in clinical research in all three countries. The content of these documents was systematically categorized and analyzed. Results The normative framework in all three countries shows a strong commitment towards the core ethical principles of research envisaged in the Declaration of Helsinki. Nevertheless, provisions on informed consent vary between these three countries. The differences range from the method and language in which information should be provided, through the amount of information required to be disclosed, to the form of documenting consent or withdrawal. In the case of research on vulnerable groups, these differences are particularly visible. Conclusions The identified differences can negatively impact the ethical conduct of international clinical studies. Attention needs to be paid that flexibilities within national regulations are not misused to undermine the protection of research subjects. Achieving global or regional legislative harmonization might prove impossible. Such lack of legal consensus reinforces the significance of the international ethical agreements. Trial registration: Not applicable.
