Introduction: Adolescents and young adults (AYAs), especially those from underserved communities, often face barriers to sexual and reproductive health (SRH). This pilot study evaluated the implementation of mobile health technologies to promote SRH care, including the integration of the Rapid Adolescent Prevention Screening^TM (RAAPS) and the Health-E You/Salud iTu^TM (Health-E You) app at a School-Based Health Center (SBHC) in Los Angeles using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Methods: This multi-method pilot study included the implementation of an integrated tool with two components, the RAAPS electronic health screening tool and the Health-E You app, which delivers tailored SRH education and contraceptive decision support to patients (who were sex-assigned as female at birth) and provides an electronic summary to clinicians to better prepare them for the visit with their patient. Quantitative data on tool usage were collected directly from the back-end data storage for the apps, and qualitative data were obtained through semi-structured interviews and in-clinic observations. Thematic analysis was conducted to identify implementation barriers and facilitators. Results: Between April 2024 and June 2024, 60 unique patients (14–19 years of age) had a healthcare visit. Of these, 35.00% used the integrated RAAPS/Health-E You app, and 88.33% completed the Health-E You app only. All five clinic staff were interviewed and expressed that they valued the tools for their educational impact, noting that they enhanced SRH discussions and helped uncover sensitive information that students might not disclose face-to-face. However, the tools affected clinic workflows and caused rooming delays due to the time-intensive setup process and lack of integration with the clinic’s primary electronic medical record system. In addition, they also reported that the time to complete the screener and app within the context of a 30-min appointment limited the time available for direct patient care. Additionally, staff reported that some students struggled with the two-step process and did not complete all components of the tool. Despite these challenges, clinic staff strongly supported renewing the RAAPS license and continued use of the Health-E You app, emphasizing the platform’s potential for improving SRH care and its educational value. Conclusions: The integrated RAAPS and Health-E You app platform demonstrated educational value and improved SRH care but faced operational and technical barriers in implementing the tool. These findings emphasize the potential of such tools to address SRH disparities among vulnerable AYAs while providing a framework for future implementations in SBHCs. Full article

Despite advances in technology, the overall management of type 1 diabetes mellitus (T1DM) remains suboptimal. The idea of restricting carbohydrate intake to decrease glycemic spikes and insulin requirements has been revisited in recent years. After impressive results in the fields of type 2 diabetes (T2DM) and epilepsy, low-carbohydrate (LCD) and ketogenic (KD) diets have gained renewed interest as a possible treatment option for T1DM. In this narrative review, we discuss the available data regarding LCDs and KDs in both the adult and pediatric populations. Research data is still scarce, as most studies are short-term and show considerable heterogeneity in dietary composition and patient outcomes. In general, carbohydrate restriction enhances glycemic control by reducing postprandial glucose excursions, improving time-in-range, and lowering HbA1c, with conflicting effects on other parameters such as lipid profile and body weight. Adverse effects such as hypoglycemia and diabetic ketoacidosis are rarely reported, although some concerns have been raised regarding growth in children. The correct implementation of these diets requires a multidisciplinary approach by highly specialized healthcare professionals, who will address the medical, social, and psychological concerns that a restrictive diet entails. Large-scale and long-term studies are needed to provide more robust data before carbohydrate restriction can be widely applied to patients with T1DM. Full article

Blockchain technology (BT) is increasingly recognized as a transformative digital infrastructure for advancing environmental, economic, and social sustainability. However, academic research on its sustainability potential remains fragmented, with limited integration of theoretical models, sector-specific applications, and system-level impacts. This study addresses these gaps by conducting a systematic literature review of 131 peer-reviewed articles published between 2015 and early 2025, guided by the PRISMA 2020 framework. The analysis is structured around the three pillars of sustainability, exploring the mechanisms through which blockchain enables transparent governance, ethical consumption, resilient infrastructure, and inclusive development. Anchored in Institutional and Stakeholder theories, the review develops an integrative dual-framework that overlays four technical components of BT (data, network, consensus, and application) onto institutional pressures and stakeholder-engagement dynamics. The framework shows how BT enhances resource efficiency, supply-chain traceability, and social inclusion across sectors such as renewable energy, agriculture, healthcare, education, and logistics. The study makes two principal contributions. First, it unifies previously dispersed findings into a holistic model that links BT’s technical capabilities with organizational and societal conditions. Second, it provides actionable guidance: policymakers should harmonize cross-border standards and incentivize energy-efficient consensus protocols, while managers should co-design stakeholder-inclusive pilots to scale sustainable BT solutions. Collectively, these insights map a research and practice agenda for leveraging blockchain to accelerate progress toward the Sustainable Development Goals. Full article

Background: One of the foremost causes of microbial infections and propagation is improper sanitation and hygiene maintained in public places. Accumulation of stains and microbes results in the spread of infections. Also, due to the extensive use of non-renewable materials like petrochemicals, etc., there is an increasing demand for sustainable growth in the coating industries. Currently, there is no such technology that tackles this problem. Methods: Our present work aims to find a prolonged solution for these problems for the first time by synthesizing and formulating bio-based coatings with inherent antimicrobial properties and durable surface properties with a fast air-curing system. A formulation of alkyd and polyesteramide resins from castor, neem, and karanja oils was crosslinked with isocyanates to form the surface coatings. An esterification reaction of castor oil monoglyceride and phthalic anhydride synthesized the castor oil alkyd resin. The corresponding neem and karanja oil polyesteramides were synthesized by amidation with diethanolamine, followed by an esterification reaction. Results: The coatings exhibit an antimicrobial efficacy of 74%–84% against both Gram-positive and Gram-negative bacteria and contain 76.5% bio-based content. Factors such as thermal stability, physicochemical properties, and chemical and solvent stability were studied. After 24 h of inoculation with 40% polyesteramide resin (AMRESN-4), E. coli and S. aureus CFU values decreased from 6 × 10⁵ to 0.28 × 10⁵ CFU/g and from 5.7 × 10⁵ to 0.26 × 10⁵ CFU/g, respectively. These bio-based coatings are particularly suited for environments requiring high durability and antimicrobial protection, such as food-processing facilities, healthcare settings, and public restrooms.

Artificial intelligence (AI), the wide spectrum of technologies aiming to give machines or computers the ability to perform human-like cognitive functions, began in the 1940s with the first abstract models of intelligent machines. Soon after, in the 1950s and 1960s, machine learning algorithms such as neural networks and decision trees ignited significant enthusiasm. More recent advancements include the refinement of learning algorithms, the development of convolutional neural networks to efficiently analyze images, and methods to synthesize new images. This renewed enthusiasm was also due to the increase in computational power with graphical processing units and the availability of large digital databases to be mined by neural networks. AI soon began to be applied in medicine, first through expert systems designed to support the clinician’s decision and later with neural networks for the detection, classification, or segmentation of malignant lesions in medical images. A recent prospective clinical trial demonstrated the non-inferiority of AI alone compared with a double reading by two radiologists on screening mammography. Natural language processing, recurrent neural networks, transformers, and generative models have both improved the capabilities of making an automated reading of medical images and moved AI to new domains, including the text analysis of electronic health records, image self-labeling, and self-reporting. The availability of open-source and free libraries, as well as powerful computing resources, has greatly facilitated the adoption of deep learning by researchers and clinicians. Key concerns surrounding AI in healthcare include the need for clinical trials to demonstrate efficacy, the perception of AI tools as ‘black boxes’ that require greater interpretability and explainability, and ethical issues related to ensuring fairness and trustworthiness in AI systems. Thanks to its versatility and impressive results, AI is one of the most promising resources for frontier research and applications in medicine, in particular for oncological applications. Full article
