A Tale of a Trail on How It Takes 5 Days of Kawasaki Disease to Initiate Coronary Artery Injury and Change the Lives of Children.

Many articles written on Kawasaki disease explain the disease and the history of an acute inflammatory dysregulation that typically affects preschool children and does not spare older ones. Six decades have passed since the discovery of the disease in Japan, yet there are parts of the world where the disease passes unacknowledged, diagnosis is delayed, or basic treatments are not readily available. The burden of Kawasaki disease is on every health-care provider who attends to children's health. It takes 5 days for the disease to initiate coronary artery injury in a child's heart, compared to 5 decades of lifetime atherosclerosis. Challenges facing patients, families, and physicians may not be overcome unless we advocate for the disease recognition and seek support for affordable, timely treatment, impactful research, and dissemination of knowledge. The purpose of this review is to provide a comprehensive review of the history of Kawasaki disease and how it has affected children's health worldwide over the last 6 decades. The review also raises current challenges facing the fight against Kawasaki disease. In an effort to bring Kawasaki disease advocates together in a landing zone, an internet hub for Kawasaki disease experts and enthusiasts has been created: the International Kawasaki Disease Society (presently a concept idea) and a dedicated website, www.ikds-org.

Carbon dots based fluorescence sensor for P-nitrophenol

P-nitrophenol (p-NP) is a hazardous chemical contaminant that can enter the body and cause health issues. The current sensor for detecting p-NP is complex to operate and cannot be used on-site. Therefore, it is essential to develop a highly sensitive and selective material for the determination of p-NP in real-time, such as a fluorescence sensor. Carbon dots (CDs) possess exceptional photoluminescence (PL) properties, making them promising for sensing applications. This review presents the recent advancement, synthesis strategies, and optical properties of CDs fluorescence sensors. Additionally, we enlighten the application and current challenges of the use of CDs as a sensor for detecting p-NP.

Intestinal organoid modeling: bridging the gap from experimental model to clinical translation.

The 3D culture of intestinal organoids entails embedding isolated intestinal crypts and bone marrow mesenchymal stem cells within a growth factor-enriched matrix gel. This process leads to the formation of hollow microspheres with structures resembling intestinal epithelial cells, which are referred to as intestinal organoids. These structures encompass various functional epithelial cell types found in the small intestine and closely mimic the organizational patterns of the small intestine, earning them the name "mini-intestines". Intestinal tumors are prevalent within the digestive system and represent a significant menace to human health. Through the application of 3D culture technology, miniature colorectal organs can be cultivated to retain the genetic characteristics of the primary tumor. This innovation offers novel prospects for individualized treatments among patients with intestinal tumors. Presently established libraries of patient-derived organoids serve as potent tools for conducting comprehensive investigations into tissue functionality, developmental processes, tumorigenesis, and the pathobiology of cancer. This review explores the origins of intestinal organoids, their culturing environments, and their advancements in the realm of precision medicine. It also addresses the current challenges and outlines future prospects for development.

Where Are All the Specialists? Current Challenges of Integrating Specialty Care Into Population-Based Total Cost of Care Payment Models.

The Centers for Medicare & Medicaid Services Innovation Center (CMMI) has set the goal for 100% of traditional Medicare beneficiaries to be part of an accountable care relationship by 2030. Lack of meaningful financial incentives, intolerable or unpredictable risk, infrastructure costs, patient engagement, voluntary participation, and operational complexity have been noted by the provider and health care delivery community as barriers to participation or reasons for exiting programs. In addition, most piloted and implemented population-based total cost of care (PB-TCOC) payment models have focused on the role of the primary care physician being the accountability (that is, attributable) leader of a patient's multifaceted care team as well as acting as the mayor of the "medical neighborhood," leaving the role of specialty care physicians undefined. Successful provider specialist integration into PB-TCOC models includes meaningful participation of specialists in achieving whole-person, high-value care where all providers are financially motivated to participate; there is unambiguous prospective attribution and clearly defined accountability for each participating party throughout the care journey or episode; there is a known care attribution transition accountability plan; there is actionable, transparent, and timely data available with appropriate data development and basic analytic costs covered; and there is advanced payment to the accountable person or entity for management of the care episode that is part of a longitudinal care plan. Payment models should be created to address the 7 challenges raised here if specialists are to be incented to join TCOC models that achieve CMMI's goal.

JAK/STAT3 signaling in cardiac fibrosis: a promising therapeutic target.

Cardiac fibrosis is a serious health problem because it is a common pathological change in almost all forms of cardiovascular diseases. Cardiac fibrosis is characterized by the transdifferentiation of cardiac fibroblasts (CFs) into cardiac myofibroblasts and the excessive deposition of extracellular matrix (ECM) components produced by activated myofibroblasts, which leads to fibrotic scar formation and subsequent cardiac dysfunction. However, there are currently few effective therapeutic strategies protecting against fibrogenesis. This lack is largely because the molecular mechanisms of cardiac fibrosis remain unclear despite extensive research. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling cascade is an extensively present intracellular signal transduction pathway and can regulate a wide range of biological processes, including cell proliferation, migration, differentiation, apoptosis, and immune response. Various upstream mediators such as cytokines, growth factors and hormones can initiate signal transmission via this pathway and play corresponding regulatory roles. STAT3 is a crucial player of the JAK/STAT pathway and its activation is related to inflammation, malignant tumors and autoimmune illnesses. Recently, the JAK/STAT3 signaling has been in the spotlight for its role in the occurrence and development of cardiac fibrosis and its activation can promote the proliferation and activation of CFs and the production of ECM proteins, thus leading to cardiac fibrosis. In this manuscript, we discuss the structure, transactivation and regulation of the JAK/STAT3 signaling pathway and review recent progress on the role of this pathway in cardiac fibrosis. Moreover, we summarize the current challenges and opportunities of targeting the JAK/STAT3 signaling for the treatment of fibrosis. In summary, the information presented in this article is critical for comprehending the role of the JAK/STAT3 pathway in cardiac fibrosis, and will also contribute to future research aimed at the development of effective anti-fibrotic therapeutic strategies targeting the JAK/STAT3 signaling.

Exploring the intricate cross-talk between clonal expansion and the bone marrow niche

Haematopoietic stem cells (HSCs) reside within an intricate network of cells in the bone marrow (BM) niche. HSC crosstalk with niche compartments influences lineage determination and blood cell production, while independent niche interactions are essential for the maintenance of HSC quiescence. How different niche components influence the genetic diversity of HSCs represents an expanding field of investigation. As such, we will summarise the current knowledge of the contribution to the Darwinian evolution of mutant HSCs of both haematopoietic and non-haematopoietic cells residing in the BM. In this review, we will disentangle how somatic evolution associates with the niche at two stages: from (1) the stage of preleukaemic HSC expansion and clonal haematopoiesis (CH) to (2) leukaemia-initiating cells (LICs) and the development of myeloid malignancies with acute myeloid leukaemia (AML) being the most prevalent. We will finally describe current challenges such as limitations in models used in the field or the difficulty in studying specific genetic clones in isolation.

Immune interface interference vaccines: An evolution-informed approach to anti-bacterial vaccine design.

Developing protein-based vaccines against bacteria has proved much more challenging than producing similar immunisations against viruses. Currently, anti-bacterial vaccines are designed using methods based on reverse vaccinology. These identify broadly conserved, immunogenic proteins using a combination of genomic and high-throughput laboratory data. While this approach has successfully generated multiple rationally designed formulations that show promising immunogenicity in animal models, few have been licensed. The difficulty of inducing protective immunity in humans with such vaccines mirrors the ability of many bacteria to recolonise individuals despite recognition by natural polyvalent antibody repertoires. As bacteria express too many antigens to evade all adaptive immune responses through mutation, they must instead inhibit the efficacy of such host defences through expressing surface structures that interface with the immune system. Therefore, 'immune interface interference' (I3) vaccines that target these features should synergistically directly target bacteria and prevent them from inhibiting responses to other surface antigens. This approach may help us understand the efficacy of the two recently introduced immunisations against serotype B meningococci, which both target the Factor H-binding protein (fHbp) that inhibits complement deposition on the bacterial surface. Therefore, I3 vaccine designs may help overcome the current challenges of developing protein-based vaccines to prevent bacterial infections.

Engineering models of head and neck and oral cancers on-a-chip.

Head and neck cancers (HNCs) rank as the sixth most common cancer globally and result in over 450 000 deaths annually. Despite considerable advancements in diagnostics and treatment, the 5-year survival rate for most types of HNCs remains below 50%. Poor prognoses are often attributed to tumor heterogeneity, drug resistance, and immunosuppression. These characteristics are difficult to replicate using in vitro or in vivo models, culminating in few effective approaches for early detection and therapeutic drug development. Organs-on-a-chip offer a promising avenue for studying HNCs, serving as microphysiological models that closely recapitulate the complexities of biological tissues within highly controllable microfluidic platforms. Such systems have gained interest as advanced experimental tools to investigate human pathophysiology and assess therapeutic efficacy, providing a deeper understanding of cancer pathophysiology. This review outlines current challenges and opportunities in replicating HNCs within microphysiological systems, focusing on mimicking the soft, glandular, and hard tissues of the head and neck. We further delve into the major applications of organ-on-a-chip models for HNCs, including fundamental research, drug discovery, translational approaches, and personalized medicine. This review emphasizes the integration of organs-on-a-chip into the repertoire of biological model systems available to researchers. This integration enables the exploration of unique aspects of HNCs, thereby accelerating discoveries with the potential to improve outcomes for HNC patients.

A Survey on Dialogue Management in Human-Robot Interaction

As social robots see increasing deployment within the general public, improving the interaction with those robots is essential. Spoken language offers an intuitive interface for the human-robot interaction (HRI), with dialogue management (DM) being a key component in those interactive systems. Yet, to overcome current challenges and manage smooth, informative and engaging interaction a more structural approach to combining HRI and DM is needed. In this systematic review, we analyse the current use of DM in HRI and focus on the type of dialogue manager used, its capabilities, evaluation methods and the challenges specific to DM in HRI. We identify the challenges and current scientific frontier related to the DM approach, interaction domain, robot appearance, physical situatedness and multimodality.

Data Protection Issues in Automated Decision-Making Systems Based on Machine Learning: Research Challenges

Data protection issues stemming from the use of machine learning algorithms that are used in automated decision-making systems are discussed in this paper. More precisely, the main challenges in this area are presented, putting emphasis on how important it is to simultaneously ensure the accuracy of the algorithms as well as privacy and personal data protection for the individuals whose data are used for training the corresponding models. In this respect, we also discuss how specific well-known data protection attacks that can be mounted in processes based on such algorithms are associated with a lack of specific legal safeguards; to this end, the General Data Protection Regulation (GDPR) is used as the basis for our evaluation. In relation to these attacks, some important privacy-enhancing techniques in this field are also surveyed. Moreover, focusing explicitly on deep learning algorithms as a type of machine learning algorithm, we further elaborate on one such privacy-enhancing technique, namely, the application of differential privacy to the training dataset. In this respect, we present, through an extensive set of experiments, the main difficulties that occur if one needs to demonstrate that such a privacy-enhancing technique is, indeed, sufficient to mitigate all the risks for the fundamental rights of individuals. More precisely, although we manage—by the proper configuration of several algorithms’ parameters—to achieve accuracy at about 90% for specific privacy thresholds, it becomes evident that even these values for accuracy and privacy may be unacceptable if a deep learning algorithm is to be used for making decisions concerning individuals. The paper concludes with a discussion of the current challenges and future steps, both from a legal as well as from a technical perspective.

Recent Advances in Nanomaterials for the Treatment of Acute Kidney Injury.

Acute kidney injury (AKI) is a serious clinical syndrome with high morbidity, elevated mortality, and poor prognosis, commonly considered a "sword of Damocles" for hospitalized patients, especially those in intensive care units. Oxidative stress, inflammation, and apoptosis, caused by the excessive production of reactive oxygen species (ROS), play a key role in AKI progression. Hence, the investigation of effective and safe antioxidants and inflammatory regulators to scavenge overexpressed ROS and regulate excessive inflammation has become a promising therapeutic option. However, the unique physiological structure and complex pathological alterations in the kidneys render traditional therapies ineffective, impeding the residence and efficacy of most antioxidant and anti-inflammatory small molecule drugs within the renal milieu. Recently, nanotherapeutic interventions have emerged as a promising and prospective strategy for AKI, overcoming traditional treatment dilemmas through alterations in size, shape, charge, and surface modifications. This Review succinctly summarizes the latest advancements in nanotherapeutic approaches for AKI, encompassing nanozymes, ROS scavenger nanomaterials, MSC-EVs, and nanomaterials loaded with antioxidants and inflammatory regulator. Following this, strategies aimed at enhancing biocompatibility and kidney targeting are introduced. Furthermore, a brief discussion on the current challenges and future prospects in this research field is presented, providing a comprehensive overview of the evolving landscape of nanotherapeutic interventions for AKI.

Perspectives of rural farmer households on food security through a qualitative study in Indonesia

In developing countries, rural farmers contribute significantly to food production, but their households are still vulnerable to poverty, food insecurity, malnutrition, and stunting. Although quantitative studies have explored the factors that influence farmers' dietary diversity, the data can be improved by integrating farmers' experiences and perspectives on whether and how these factors affect their dietary diversity. Malnutrition and food insecurity are more prevalent in developing and underdeveloped nations like Africa and Southeast Asia. Due to increased work, this country usually sees a rise in stunting, malnutrition, and increased physical activity. Stunting has a higher prevalence than other nutritional disorders, such as malnutrition, according to Nutrition Status Monitoring (NSM) data over the last three years. The frequency of stunting in children under five has risen from 27% in 2016 to 29% in 2017. This will assist in designing and implementing interventions. Forty rural farmers in Bone Regency, Indonesia, became informants in targeted interviews as part of the qualitative study (20 male and 20 female farmers). According to the research results, both male and female informants were concerned about the availability and variety of food. They feel that household food production is essential to achieve food security. Food sales are affected by prices, household income, distance to markets, and the range of food available. Household food production, knowledge, nutrition, availability, use of information, time, and household income are significant determinants of the variety of food consumed. In farming households, gender influences and variations on the distribution and use of food collected and income are explored. Men have more time to engage in agricultural endeavors that promote dietary diversity. Based on these findings, efforts to increase dietary diversity should address current food security and production challenges, support increased farm incomes and market access, utilize designs that address gender issues, and include nutrition capacity building, diverse practices, and social behavior change strategies. Key words: rural farmers, food security, food diversity, nutrition, market access, Indonesia
