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

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

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

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 ß-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

El objetivo es evaluar un seguimiento telemático (web o aplicación [app]) para pacientes con sobrepeso/obesidad y otros dos factores de riesgo cardiovascular: hipertensión arterial (HTA), dislipemia, diabetes mellitus (DM), sedentarismo, consumo tabáquico. Diseño: es un estudio de intervención con asignación aleatoria al grupo intervención (web o app) y al grupo control. Emplazamiento: centros de salud rurales y urbanos, docentes y no docentes, del Sector Zaragoza I. Participantes: 261 personas con índice de masa corporal (IMC) > 25 kg/m2 y otros dos factores de riesgo. Intervenciones: seguimiento de 18 meses con puntos de corte al inicio, 1, 6, 12 y 18 meses. Las mediciones principales son peso, tensión arterial, consumo tabáquico, eventos cardiovasculares, calidad de vida y bioquímica. Resultados: el grupo control finalizó el estudio en mayor proporción (79% versus 14%). El grupo control consiguió una pérdida del 8% de la mediana de peso al año y el grupo intervención un 5%. A los 6 meses, el grupo control logró disminuir el 7% la tensión arterial sistólica y el 5% la diastólica. La hemoglobina glicosilada (HbA1c) descendió un 1% en el grupo control y un 0,5% en el grupo intervención (test de Wilcoxon: 10; p = 0,089). El colesterol de lipoproteínas de baja densidad (cLDL) del grupo control descendió 9 mg/dL, y el del grupo intervención, 7 mg/dl (test de Wilcoxon: 1.089; p = 0,018). El hábito tabáquico disminuyó en todos los grupos (test de Wilcoxon: 21; p = 0,036). El grupo control presentó mayor prevalencia de eventos cardiovasculares. La calidad de vida mejoró en todos los grupos (test Wilcoxon: 979; p = 0,041). Conclusiones: las/los pacientes que acuden al centro de salud para un seguimiento de peso consiguen mejores resultados que si el seguimiento se hace de forma telemática.(AU)

ABSTRACT

The rise in innovative digital health technologies has led a paradigm shift in health care toward personalized, patient-centric medicine that is reaching beyond traditional brick-and-mortar facilities into patients' homes and everyday lives. Digital solutions can monitor and detect early changes in physiological data, predict disease progression and health-related outcomes based on individual risk factors, and manage disease intervention with a range of accessible telemedicine and mobile health options. In this review, we discuss the unique transformation underway in the care of patients with liver disease, specifically examining the digital transformation of diagnostics, prediction and clinical decision-making, and management. Additionally, we discuss the general considerations needed to confirm validity and oversight of new technologies, usability and acceptability of digital solutions, and equity and inclusivity of vulnerable populations.

ABSTRACT

Nanomaterials, especially superparamagnetic nanomaterials, have recently played essential roles in point-of-care testing due to their intrinsic magnetic, electrochemical, and optical properties. The inherent superparamagnetism of magnetic nanoparticles makes them highly sensitive for quantitative detection. Among the various magnetic detection technologies, frequency mixing technology (FMT) technology is an emerging detection technique in the nanomedical field. FMT sensors have high potential for development in the field of biomedical quantitative detection due to their simple structure, and they are not limited to the materials used. In particular, they can be applied for large-scale disease screening, early tumor marker detection, and low-dose drug detection. This review summarizes the principles of FMT and recent advances in the fields of immunoadsorption, lateral flow assay detection, magnetic imaging, and magnetic nanoparticles recognition. The advantages and limitations of FMT sensors for robust, ultrasensitive biosensing are highlighted. Finally, the future requirements and challenges in the development of this technology are described. This review provides further insights for researchers to inspire the future development of FMT by integration into biosensing and devices with a broad field of applications in analytical sensing and clinical usage.

ABSTRACT

BACKGROUND: Operating microscopes and adjunctive technologies are continually refined to advance microneurosurgical care. How frequently these advances are used is unknown. In the present study, we assessed the international adoption of microneurosurgical technologies and discussed their value. METHODS: A 27-question electronic survey was distributed to cerebrovascular neurosurgeon members of U.S., European, and North American neurosurgical societies and social media networks of cerebrovascular and skull base neurosurgeons. The survey encompassed the surgeons' training background, surgical preferences, and standard microneurosurgical practices. RESULTS: Of the respondents, 56% (53 of 95) were attendings, 74% (70 of 95) were in their first 10 years of practice, and 67% (63 of 94) practiced at an academic teaching hospital. Vascular, endovascular, and skull base fellowships had been completed by 38% (36 of 95), 27% (26 of 95), and 32% (30 of 95) of the respondents, respectively. Most respondents did not use an exoscope (78%; 73 of 94), a mouthpiece (61%; 58 of 95), or foot pedals (56%; 55 of 94). All 95 respondents used a microscope, and 71 (75%) used Zeiss microscopes. Overall, 57 neurosurgeons (60%) used indocyanine green for aneurysms (n = 54), arteriovenous malformations (n = 43), and dural arteriovenous fistulas (n = 42). Most (80%; 75 of 94) did not use fluorescence. The respondents with a vascular-focused practice more commonly used indocyanine green, Yellow 560 fluorescence, and intraoperative 2-dimensional digital subtraction angiography. The respondents with a skull base-focused practice more commonly used foot pedals and an endoscope-assist device. CONCLUSIONS: The results from the present survey have characterized the current adoption of operative microscopes and adjunctive technologies in microneurosurgery. Despite numerous innovations to improve the symbiosis between neurosurgeon and microscope, their adoption has been underwhelming. Future advances are essential to improve surgical outcomes.

ABSTRACT

Artificial Intelligence (AI) relies upon a convergence of technologies with further synergies with life science technologies to capture the value of massive multi-modal data in the form of predictive models supporting decision-making. AI and machine learning (ML) enhance drug design and development by improving our understanding of disease heterogeneity, identifying dysregulated molecular pathways and therapeutic targets, designing and optimizing drug candidates, as well as evaluating in silico clinical efficacy. By providing an unprecedented level of knowledge on both patient specificities and drug candidate properties, AI is fostering the emergence of a computational precision medicine allowing the design of therapies or preventive measures tailored to the singularities of individual patients in terms of their physiology, disease features, and exposure to environmental risks.

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

INTRODUCTION: Digital health technologies may be useful tools in the management of chronic diseases. We performed a systematic review of digital health interventions in the management of patients with inflammatory bowel diseases (IBD) and evaluated its impact on (i) disease activity monitoring, (ii) treatment adherence, (iii) quality of life (QoL) measures, and/or (iv) health care utilization. METHODS: Through a systematic review of multiple databases through August 31, 2020, we identified randomized controlled trials in patients with IBD comparing digital health technologies vs standard of care (SoC) for clinical management and monitoring and reporting impact on IBD disease activity, treatment adherence, QoL, and/or health care utilization or cost-effectiveness. We performed critical qualitative synthesis of the evidence supporting digital health interventions in patients with IBD and rated certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Overall, we included 14 randomized controlled trials (median, 98 patients; range 34-909 patients; follow-up <12 months) that compared web-based interventions, mobile applications, and different telemedicine platforms with SoC (clinic-based encounters). Although overall disease activity and risk of relapse were comparable between digital health technologies and SoC (very low certainty of evidence), digital health interventions were associated with lower rate of health care utilization and health care costs (low certainty of evidence). Digital health interventions did not significantly improve patients' QoL and treatment adherence compared with SoC (very low certainty of evidence). Trials may have intrinsic selection bias due to nature of digital interventions. DISCUSSION: Digital health technologies may be effective in decreasing health care utilization and costs, though may not offer advantage in reducing risk of relapse, QoL, and improving treatment adherence in patients with IBD. These techniques may offer value-based care for population health management.

ABSTRACT

In biomedical networks, molecular associations are important to understand biological processes and functions. Many computational methods, such as link prediction methods based on graph neural networks (GNNs), have been successfully applied in discovering molecular relationships with biological significance. However, it remains a challenge to explore a method that relies on representation learning of links for accurately predicting molecular associations. In this paper, we present a novel GNN based on link representation (LR-GNN) to identify potential molecular associations. LR-GNN applies a graph convolutional network (GCN)-encoder to obtain node embedding. To represent associations between molecules, we design a propagation rule that captures the node embedding of each GCN-encoder layer to construct the LR. Furthermore, the LRs of all layers are fused in output by a designed layer-wise fusing rule, which enables LR-GNN to output more accurate results. Experiments on four biomedical network data, including lncRNA-disease association, miRNA-disease association, protein-protein interaction and drug-drug interaction, show that LR-GNN outperforms state-of-the-art methods and achieves robust performance. Case studies are also presented on two datasets to verify the ability to predict unknown associations. Finally, we validate the effectiveness of the LR by visualization.

ABSTRACT

BACKGROUND: Mobile health (mHealth) technology has been proposed as a method of improving post-discharge surveillance. Little is known about how mHealth has been used to track patients after surgery and whether its use is associated with differences in postoperative recovery. METHODS: Three databases (PubMed, MEDLINE and the Cochrane Central Registry of Controlled Trials) were searched to identify studies published between January 1999 and February 2021. Mobile health was defined as any smartphone or tablet computer capable of electronically capturing health-related patient information and transmitting these data to the clinical team. Comparable outcomes were pooled via meta-analysis with additional studies compiled via narrative review. The quality of each study was assessed based on Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. RESULTS: Forty-five articles met inclusion criteria. While the majority of devices were designed to capture general health information, others were specifically adapted to the expected outcomes or potential complications of the index procedure. Exposure to mHealth was associated with fewer emergency department visits (odds ratio 0.42, 95 per cent c.i. 0.23 to 0.79) and readmissions (odds ratio 0.47, 95 per cent c.i. 0.29 to 0.77) as well as accelerated improvements in quality of life after surgery. There were limited data on other postoperative outcomes. CONCLUSION: Remote home monitoring via mHealth is feasible, adaptable, and may even promote more effective postoperative care. Given the rapid expansion of mHealth, physicians and policymakers need to understand these technologies better so that they can be integrated into high-quality clinical care.


A systematic review was performed to determine how mobile health (mHealth) technology is being used to track surgical patients after hospital discharge, and whether exposure to mHealth is associated with differences in postoperative recovery. Remote home monitoring via mHealth is feasible and flexible enough to meet the demands of a variety of patients and clinical teams. Exposure to mHealth also appears to be associated with a reduction in both emergency department visits and hospital readmissions as well as accelerated improvements in quality of life. mHealth represents an important next step in postoperative surveillance, although better performance data, targeted incentives and clearer guidelines are still needed.

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.
