Digital health technologies in enhancing patient and caregiver engagement in heart failure management: Opportunities and challenges. Int J Cardiol 2024; 408:132116. [PMID: 38703898 DOI: 10.1016/j.ijcard.2024.132116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 04/04/2024] [Accepted: 04/29/2024] [Indexed: 05/06/2024]
Abstract
The management of heart failure has undergone significant evolution, advancing from the initial utilization of digitalis and diuretics to the contemporary practice of personalized medicine and sophisticated device therapy. Despite these advancements, the persistent challenge of high hospitalization and readmission rates underscores an urgent need for innovative solutions. This manuscript explores how the integration of digital health technologies into interventional cardiology marks a paradigm shift in the management of heart failure. These technologies are no longer mere adjuncts but have become foundational to a modern approach, providing tools for continuous monitoring, patient education, and improved outcomes post-intervention. Through an examination of current trends, this perspective article highlights the transformative impact of wearable technologies, telehealth platforms, and advanced analytical tools in reshaping patient engagement and enabling proactive care strategies. Case studies illustrate the practical advantages, including enhanced medication adherence, early detection of heart failure signs, and a reduction in healthcare facility burdens. Central to this new digital health landscape is the Information Technology Management (ITM) system, a framework poised to revolutionize patient and caregiver engagement and pave the way for the future of interventional cardiology. This manuscript delineates the ITM system's innovative architecture and its consequential role in refining current and prospective cardiological interventions.

Abstract
INTRODUCTION Digital Health Technologies (DHTs) have been shown to have variable usability as measured by efficiency, effectiveness and user satisfaction despite large-scale government projects to regulate and standardise user interface (UI) design. We hypothesised that Human-Computer Interaction (HCI) modelling could improve the methodology for DHT design and regulation, and support the creation of future evidence-based UI standards and guidelines for DHTs. METHODOLOGY Using a Design Science Research (DSR) framework, we developed novel UI components that adhered to existing standards and guidelines (combining the NHS Common User Interface (CUI) standard and the NHS Design System). We firstly evaluated the Patient Banner UI component for compliance with the two guidelines and then used HCI-modelling to evaluate the "Add New Patient" workflow to measure time to task completion and cognitive load. RESULTS Combining the two guidelines to produce new UI elements is technically feasible for the Patient Banner and the Patient Name Input components. There are some inconsistencies between the NHS Design System and the NHS CUI when implementing the Patient Banner. HCI-modelling successfully quantified challenges adhering to the NHS CUI and the NHS Design system for the "Add New Patient" workflow. DISCUSSION We successfully developed new design artefacts combing two major design guidelines for DHTs. By quantifying usability issues using HCI-modelling, we have demonstrated the feasibility of a methodology that combines HCI-modelling into a human-centred design (HCD) process could enable the development of standardised UI elements for DHTs that is more scientifically robust than HCD alone. CONCLUSION Combining HCI-modelling and Human-Centred Design could improve scientific progress towards developing safer and more user-friendly DHTs.

Abstract
INTRODUCTION Over the last decade increasing examples indicate opportunities to measure patient functioning and its relevance for clinical and regulatory decision making via endpoints collected through digital health technologies. More recently, we have seen such measures support primary study endpoints and enable smaller trials. The field is advancing fast: validation requirements have been proposed in the literature and regulators are releasing new guidances to review these endpoints. Pharmaceutical companies are embracing collaborations to develop them and working with academia and patient organizations in their development. However, the road to validation and regulatory acceptance is lengthy. The full value of digital endpoints cannot be unlocked until better collaboration and modular evidence frameworks are developed enabling re-use of evidence and repurposing of digital endpoints. AREAS COVERED This paper proposes a solution by presenting a novel modular evidence framework -the Digital Evidence Ecosystem and Protocols (DEEP)- enabling repurposing of measurement solutions, re-use of evidence, application of standards and also facilitates collaboration with health technology assessment bodies. EXPERT OPINION The integration of digital endpoints in healthcare, essential for personalized and remote care, requires harmonization and transparency. The proposed novel stack model offers a modular approach, fostering collaboration and expediting the adoption in patient care.

Abstract
INTRODUCTION Sensor-based digital health technology (DHT) has emerged as a promising means to assess patient functioning within and outside clinical trials. Sensor-based functional outcomes (SBFOs) provide valuable insights that complement other measures of how a patient feels or functions to enhance understanding of the patient experience to inform medical product development. AREAS COVERED This perspective paper provides recommendations for defining SBFOs, discusses the core evidence required to support SBFOs to inform decision-making, and considers future directions for the field. EXPERT COMMENTARY The clinical outcome assessment (COA) development process provides an important starting point for developing patient-centered SBFOs; however, given the infancy of the field, SBFO development may benefit from a hybrid approach to evidence generation by merging exploratory data analysis with patient engagement in measure development. Effective SBFO development requires combining unique expertise in patient engagement, measurement and regulatory science, and digital health and analytics. Challenges specific to SBFO development include identifying concepts of interest, ensuring measurement of meaningful aspects of health, and identifying thresholds for meaningful change. SBFOs are complementary to other COAs and, as part of an integrated evidence strategy, offer great promise in fostering a holistic understanding of patient experience and treatment benefits, particularly in real-world settings.

Abstract
BACKGROUND In the context of pediatric palliative care, where the quality of life of children with life-limiting or life-threatening conditions is of utmost importance, the integration of health technology must support the provision of care. Research has highlighted the role of healthcare personnel when utilizing health technology in home-based pediatric palliative care, but specific knowledge of healthcare personnel's views on the technological relevance remains limited. Therefore, our study has explored potentials and limitations of health technology in home-based pediatric palliative care from the perspectives of healthcare personnel. METHODS Our study utilized a qualitative, descriptive, and exploratory design, including five focus groups with a total of 22 healthcare personnel. The participants were selected from various health regions in Norway and were experienced in providing home-based pediatric palliative care. Using reflexive thematic analysis, we interpreted data obtained from focus groups, identified patterns, and developed themes. RESULTS The analysis resulted in the development of three intersecting themes: balancing in-person interaction and time in home-based pediatric palliative care; exchange of information can improve timely and appropriate care; and the power of visual documentation in pediatric palliative care. The healthcare personnel acknowledged difficulties in fully replacing in-person interaction with health technology. However, they also emphasized potentials of health technology to facilitate information sharing and the ability to access a child's health record within interdisciplinary teams. CONCLUSION The results underscored that technology can support pediatric palliative care but must be thoughtfully integrated to ensure an individualized patient-centered approach. To maximize the benefits of health technology in enhancing home-based pediatric palliative care, future research should address the limitations of current health technology and consider the opinions for information sharing between relevant healthcare team members, the child, and their family.

Abstract
Peptide-based hydrogels have gained considerable attention as a compelling platform for various biomedical applications in recent years. Their attractiveness stems from their ability to seamlessly integrate diverse properties, such as biocompatibility, biodegradability, easily adjustable hydrophilicity/hydrophobicity, and other functionalities. However, a significant drawback is that most of the functional self-assembling peptides cannot form robust hydrogels suitable for biological applications. In this study, we present the synthesis of novel peptide-PEG conjugates and explore their comprehensive hydrogel properties. The hydrogel comprises double networks, with the first network formed through the self-assembly of peptides to create a β-sheet secondary structure. The second network is established through covalent bond formation via N-hydroxysuccinimide chemistry between peptides and a 4-arm PEG to form a covalently linked network. Importantly, our findings reveal that this hydrogel formation method can be applied to other peptides containing lysine-rich sequences. Upon encapsulation of the hydrogel with antimicrobial peptides, the hydrogel retained high bacterial killing efficiency while showing minimum cytotoxicity toward mammalian cells. We hope that this method opens new avenues for the development of a novel class of peptide-polymer hydrogel materials with enhanced performance in biomedical contexts, particularly in reducing the potential for infection in applications of tissue regeneration and drug delivery.

Abstract
Drug-repurposing technologies are growing in number and maturing. However, comparisons to each other and to reality are hindered because of a lack of consensus with respect to performance evaluation. Such comparability is necessary to determine scientific merit and to ensure that only meaningful predictions from repurposing technologies carry through to further validation and eventual patient use. Here, we review and compare performance evaluation measures for these technologies using version 2 of our shotgun repurposing Computational Analysis of Novel Drug Opportunities (CANDO) platform to illustrate their benefits, drawbacks, and limitations. Understanding and using different performance evaluation metrics ensures robust cross-platform comparability, enabling us to continue to strive toward optimal repurposing by decreasing the time and cost of drug discovery and development.

Abstract
BACKGROUND Recent advances in immunology, genomics, and cellular therapy have opened numerous therapeutic possibilities in pediatric hematology-oncology, generating new hope in poor prognosis situations. How decisions are made when it comes to treatments and aims needs to be explored in this new technologic context. In particular, their impact on the gold standard of early referral to palliative care must be assessed. MATERIALS AND METHODS Stemming from an ethnographic study combining semistructured interviews and observations carried out in a hematopoietic stem cell transplant unit in a Montréal Pediatric Hospital, we discuss the decision-making process when a patient faces poor prognosis. RESULTS AND DISCUSSION Although health care providers individually envisioned that palliative care may be the best course of action for patients receiving emergent therapy, they remained collectively in the curative mode. The intricate relationship between science, hope, caregiver, and care receiver sustains this perspective even when (near) death is the probable outcome. When proven treatment fails, emerging therapeutic possibilities offer new hope that can delay the referral to the palliative care team.

Abstract
Cellular homeostasis is regulated by the protein quality control (PQC) machinery, comprising multiple chaperones and enzymes. Studies suggest that the loss of the PQC mechanisms in neurons may lead to the formation of abnormal inclusions that may lead to neurological disorders and defective aging. The questions could be raised how protein aggregate formation precisely engenders multifactorial molecular pathomechanism in neuronal cells and affects different brain regions? Such questions await thorough investigation that may help us understand how aberrant proteinaceous bodies lead to neurodegeneration and imperfect aging. However, these studies face multiple technological challenges in utilizing available tools for detailed characterizations of the protein aggregates or amyloids and developing new techniques to understand the biology and pathology of proteopathies. The lack of detection and analysis methods has decelerated the pace of the research in amyloid biology. Here, we address the significance of aggregation and inclusion formation, followed by exploring the evolutionary contribution of these structures. We also provide a detailed overview of current state-of-the-art techniques and advances in studying amyloids in the diseased brain. A comprehensive understanding of the structural, pathological, and clinical characteristics of different types of aggregates (inclusions, fibrils, plaques, etc.) will aid in developing future therapies.

Abstract
As a new type of nanomaterial, DNA-templated silver nanoclusters (DNA-AgNCs) have been widely studied because of their fluorescence and antibacterial properties. In this study, we combined the DNA-AgNCs with aptamers of bacteria to achieve a novel approach for the visual detection and effective elimination of bacteria. The aptamers of Staphylococcus aureus (S. aureus) were linked to G-rich sequences to achieve fluorescence enhancement when approaching the DNA-AgNCs. The capture of aptamers not only realized the visual monitoring of bacteria but also promoted the antibacterial effects. Additionally, a fluorescent nanofilm with excellent selectivity and antibacterial activity in the detection and elimination of S. aureus was developed based on the DNA-AgNCs. These aptamer-functionalized DNA-AgNCs show significant potential for many applications in food packaging and biomedical engineering.

Abstract
Enzyme therapeutics have received increasing attention due to their high biological specificity, outstanding catalytic efficiency, and impressive therapeutic outcomes. Protecting and delivering enzymes into target cells while retaining enzyme catalytic efficiency is a big challenge. Wrapping of enzymes with rational designed polymer shells, rather than trapping them into large nanoparticles such as liposomes, have been widely explored because they can protect the folded state of the enzyme and make post-functionalization easier. In this review, the methods for wrapping up enzymes with protective polymer shells are mainly focused on. It is aimed to provide a toolbox for the rational design of polymeric enzymes by introducing methods for the preparation of polymeric enzymes including physical adsorption and chemical conjugation with specific examples of these conjugates/hybrid applications. Finally, a conclusion is drawn and key points are emphasized.

Abstract
Polylactide (PLA) is among the most common biodegradable polymers, with applications in various fields, such as renewable and biomedical industries. PLA features poly(D-lactic acid) (PDLA) and poly(L-lactic acid) (PLLA) enantiomers, which form stereocomplex crystals through racemic blending. PLA emerged as a promising material owing to its sustainable, eco-friendly, and fully biodegradable properties. Nevertheless, PLA still has a low applicability for drug delivery as a carrier and scaffold. Stereocomplex PLA (sc-PLA) exhibits substantially improved mechanical and physical strength compared to the homopolymer, overcoming these limitations. Recently, numerous studies have reported the use of sc-PLA as a drug carrier through encapsulation of various drugs, proteins, and secondary molecules by various processes including micelle formation, self-assembly, emulsion, and inkjet printing. However, concerns such as low loading capacity, weak stability of hydrophilic contents, and non-sustainable release behavior remain. This review focuses on various strategies to overcome the current challenges of sc-PLA in drug delivery systems and biomedical applications in three critical fields, namely anti-cancer therapy, tissue engineering, and anti-microbial activity. Furthermore, the excellent potential of sc-PLA as a next-generation polymeric material is discussed.

Abstract
As a high-impact educational practice, cooperative learning uses a structured group study to promote students' active learning. Currently, it lacks economical yet effective tools to facilitate the interactive nature of structured cooperative learning in regular classrooms. Here, we have established a mobile technology-based cooperative learning (MBCL) platform that comprises the 2018 iPad, Apple Pencil, LiveBoard, Google Forms, and Google Drive. We tested the MBCL platform in multiple undergraduate biology courses. During semester-long MBCL studies, the students engaged in cooperative learning to discuss a real-life issue or chapter-based contents. With the MBCL platform, the students' group study processes were shown on shared, visible electronic whiteboards that were updated in real-time, generating visible thinking and instant, interactive communication. The instructor was able to guide the students promptly to conduct knowledge integration and knowledge synthesis using tables and diagrams. The deep learning outcome was evident in the examples and quantitative analyses of students' whiteboard study results and team presentations. Thus, integrating innovative mobile technologies into high-impact teaching practices, exemplified by the MBCL platform, promotes deep learning in higher education.

Abstract
BACKGROUND In diabetic foot ulceration, a correlation between pressure and skin temperature is suspected. The aim of this systematic review is to provide a more rigorous analysis of existing literature related to the various technologies used to read and measure both in-shoe plantar pressures, and in-shoe skin temperatures simultaneously. METHODS A systematic review of the literature related to the topic was searched in database sources such as Medline OVID, Cochrane Library, PubMed, CONAHL, PROSPERO, and Elsevier. Outcome measures of interest included validity, reliability and responsiveness of in-shoe temperature and/or pressure mapping device used, and characteristics and quantity of sensors used, anatomical landmarks and statistical analysis used to interpret the data. Quality of evidence and risk of bias was evaluated using the QUADAS-2. RESULTS Nineteen studies were identified and included in this review. The majority of studies used a small sample size (mean n = 17) and recruited healthy participants. All studies have shown excellent validity but only a few tested for the reliability of the device. None of the studies tested for responsiveness of the device. Quality assessment results scored high risk in view of 'patient selection', 'use of reference standard' and 'applicability', and low risk in view of 'use if index test' and 'flow and timing'. CONCLUSIONS The data outlined in this review confirms that further improvement, reliability testing and clinical validation of the developed systems is required despite the results of excellent performance in detecting changes of in-shoe skin temperature and pressure.

Glycosylated hemoglobin (HbA1c) level and self-management ability were the primary and secondary outcomes. Subject self-management ability was evaluated using the Chinese version of Perceived Diabetes Self-Management Scale (PDSMS). A linear mixed-effect model for repeated measures was used to analyze changes in HbA1c level and self-management ability after controlling for pretest effects. RESULTS The mean HbA1c levels in the experimental group decreased by 0.692% (7.564 mmol/mol) and 0.671% (7.332 mmol/mol) at 3 and 6 months after the intervention (p < 0.05) while the mean increase in the PDSMS scores at 3 and 6 months after the intervention were significantly higher than those in the control group (p < 0.05). CONCLUSION The health technology education program was more effective than routine shared care alone in lowering HbA1c and increasing self-management ability in T2D patients.

[PMID: 16329748 DOI: 10.1111/j.1444-0938.2005.tb05106.x] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2005] [Revised: 05/16/2005] [Accepted: 06/10/2005] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Our aim was to investigate the impact of manufacturing method and material composition on the surface characteristics of hydrogel contact lenses. METHODS Five lens types were examined; three polyhydroxyethyl methacrylate (pHEMA) lenses, each manufactured by a different technique, namely, lathing, spin-casting and cast-moulding, a HEMA/methacrylic acid cast-moulded lens and a HEMA/glycerol methacrylate cast-moulded lens. Six lenses of each type were examined (front and back) using scanning electron microscopy (SEM). Additionally, both surfaces of three lenses from each of the pHEMA lens groups were examined, partially hydrated, using an atomic force microscope (AFM). Qualitative data were gathered for both SEM and AFM studies in addition to root-mean-square (RMS) roughness values for the lenses investigated with AFM. RESULTS The surfaces of the lathed lenses were covered in lathing/polishing marks. RMS roughness values for the anterior surface (10.9 +/- 4.3 nm) were significantly greater (p = 0.02) than those of the posterior surface (9.3 +/- 0.8 nm). The two surfaces of the spun-cast lens appeared similar by SEM but AFM RMS roughness values were greater (p = 0.02) for the anterior (12.3 +/- 1.8 nm) than the posterior (5.8 +/- 1.9 nm) surface. Both SEM and AFM showed similar topographic appearances for the surfaces of the cast-moulded pHEMA lens, although RMS roughness values were greater (p = 0.02) for the anterior (5.8 +/- 0.9 nm) than the posterior (3.9 +/- 0.3 nm) surface. All three cast-moulded lenses had more processing debris than the lathed and spun-cast pHEMA lenses. Overall, the surfaces of the lathed lens were 'rougher' than those of the cast-moulded lens (p = 0.01). CONCLUSION The surface topographies of the hydrogel contact lenses are dependent on the method of manufacture. Cast-moulded lenses are associated with apparently 'stickier' surfaces, which may be indicative of surface degradation during the manufacturing process.

Lupton D. Young People's Use of Digital Health Technologies in the Global North: Narrative Review. J Med Internet Res 2021; 23:e18286. [PMID: 33427684 PMCID: PMC7834940 DOI: 10.2196/18286] [Citation(s) in RCA: 48] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Revised: 08/02/2020] [Accepted: 10/28/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND A diverse array of digital technologies are available to children and young people living in the Global North to monitor, manage, and promote their health and well-being. OBJECTIVE This article provides a narrative literature review of the growing number of social research studies published over the past decade that investigate the types of digital technologies used by children and young people in the Global North, in addition to investigating which of these technologies they find most useful or not useful. Key findings as well as major gaps and directions for future research are identified and discussed. METHODS A comprehensive search of relevant publications listed in Google Scholar was conducted, supported by following citation trails of these publications. The findings are listed under type of digital technology used for health: cross-media, internet, social media, apps and wearable devices, sexual health support and information, and mental health support and information. RESULTS Many young people in the Global North are active users of digital health technologies. However, it is notable that they still rely on older technologies, such as websites and search engines, to find information. Apps and platforms that may not have been specifically developed for young people as digital health resources often better suit their needs. Young people appreciate the ready availability of information online, the opportunities to learn more about their bodies and health states, and the opportunities to learn how to improve their health and physical fitness. They enjoy being able to connect with peers, and they find emotional support and relief from distress by using social media platforms, YouTube, and online forums. Young people can find the vast reams of information available to them difficult to navigate. They often look to trusted adults to help them make sense of the information they find online and to provide alternative sources of information and support. Face-to-face interactions with these trusted providers remain important to young people. Risks and harms that young people report from digital health use include becoming overly obsessed with their bodies' shape and size when using self-tracking technologies and comparing their bodies with the social media influencers they follow. CONCLUSIONS Further details on how young people are using social media platforms and YouTube as health support resources and for peer-to-peer sharing of information, including attention paid to the content of these resources and the role played by young social media influencers and microcelebrities, would contribute important insights to this body of literature. The role played by visual media, such as GIFs (Graphics Interchange Format) and memes, and social media platforms that have recently become very popular with young people (eg, Snapchat and TikTok) in health-related content creation and sharing requires more attention by social researchers seeking to better understand young people's use of digital devices and software for health and fitness.

Abstract
Cardiac explant-derived cells (cEDC), also referred as cardiac progenitors cells (CPC) (Barile et al., Cardiovasc Res 103(4):530-541, 2014; Barile et al., Cardiovasc Res 114(7):992-1005, 2018), represent promising candidates for the development of cell-based therapies, a novel and interesting treatment for cardioprotective strategy in heart failure (Kreke et al., Expert Rev Cardiovasc Ther 10(9):1185-1194, 2012). CPC have been tested in a preclinical setting for direct cell transplantation and tissue engineering or as a source for production of extracellular vesicles (EV) (Oh et al., J Cardiol 68(5):361-367, 2016; Barile et al., Eur Heart J 38(18):1372-1379, 2017; Rosen et al., J Am Coll Cardiol 64(9):922-937, 2014). CPC cultured as cardiospheres derived cells went through favorable Phase 1 and 2 studies demonstrating safety and possible efficacy (Makkar et al., Lancet 379(9819):895-904, 2012; Ishigami et al., Circ Res 120(7):1162-1173, 2017; Ishigami et al., Circ Res 116 (4):653-664, 2015; Tarui et al., J Thorac Cardiovasc Surg 150(5):1198-1207, 1208 e1191-1192, 2015). In this context and in view of clinical applications, cells have to be prepared and released according to Good Manufacturing Practices (GMP) (EudraLex-volume 4-good manufacturing practice (GMP) guidelines-Part I-basic requirements for medicinal products. http://ec.europa.eu/health/documents/eudralex/vol-4 ; EudraLex-volume 4-good manufacturing practice (GMP) guidelines-Part IV-guidelines on good manufacturing practices specific to advanced therapy medicinal products. http://ec.europa.eu/health/documents/eudralex/vol-4 ). This chapter describes GMP-grade methods for production and testing of a CPC Master Cell Bank (MCB), consisting of frozen aliquots of cells that may be used either as a therapeutic product or as source for the manufacturing of Exo for clinical trials.The MCB production method has been designed to isolate and expand CPC from human cardiac tissue in xeno-free conditions (Andriolo et al., Front Physiol 9:1169, 2018). The quality control (QC) methods have been implemented to assess the safety (sterility, endotoxin, mycoplasma, cell senescence, tumorigenicity) and identity/potency/purity (cell count and viability, RT-PCR, immunophenotype) of the cells (Andriolo et al., Front Physiol 9:1169, 2018).

Abstract
Antibody phage display is regarded as a critical tool for the development of monoclonal antibodies for infectious diseases. The different classes of antibody libraries are classified based on the source of repertoire used to generate the libraries. Immune antibody libraries are generated from disease infected host or immunization against an infectious agent. Antibodies derived from immune libraries are distinct from those derived from naïve libraries as the host's in vivo immune mechanisms shape the antibody repertoire to yield high affinity antibodies. As the immune system is constantly evolving in accordance to the health state of an individual, immune libraries can offer more than just infection-specific antibodies but also antibodies derived from the memory B-cells much like naïve libraries. The combinatorial nature of the gene cloning process would give rise to a combination of natural and un-natural antibody gene pairings in the immune library. These factors have a profound impact on the coverage of immune antibody libraries to target both disease-specific and non-disease specific antigens. This review looks at the diverse nature of antibody responses for immune library generation and discusses the extended potential of a disease-specified immune library in the context of phage display.
