Background: Non-healing diabetic wounds represent a significant clinical challenge globally, necessitating innovative approaches in drug delivery to enhance wound healing. Understanding the pathogenesis of these wounds is crucial for developing effective treatments. Bioactive dressings and polymeric nanofibers have emerged as promising modalities, with silk biomaterials gaining attention for their unique properties in diabetic wound healing. Purpose of Review: The purpose of this review is to examine the challenges and innovations in treating non-healing diabetic wounds, emphasizing the global burden and the need for effective solutions. This review explores the complex mechanisms of wound healing in diabetes and evaluates the therapeutic potential of bioactive dressings and polymeric nanofibers. Special focus is given to the application of silk biomaterials, particularly silk fibroin, for wound healing, detailing their properties, mechanisms, and clinical translation. This review also describes various nanofiber fabrication methods, especially electrospinning technology, and presents existing evidence on the effectiveness of electrospun silk fibroin formulations. Recent Findings: Recent advancements highlight the potential of silk biomaterials in diabetic wound healing, owing to their biocompatibility, mechanical strength, and controlled drug release properties. Electrospun silk fibroin-based formulations have shown promising results in preclinical and clinical studies, demonstrating accelerated wound closure and tissue regeneration. Summary: Non-healing diabetic wounds present a significant healthcare burden globally, necessitating innovative therapeutic strategies. Bioactive dressings and polymeric nanofibers, particularly silk-based formulations fabricated through electrospinning, offer promising avenues for enhancing diabetic wound healing. Further research is warranted to optimize formulation parameters and validate efficacy in larger clinical trials.

Background: Stevens-Johnson Syndrome (SJS) is an infrequent yet severe mucocutaneous reaction that involves less than 10% of the Body Surface Area (BSA). It is predominantly induced by certain medications, including anticonvulsants (e.g., Lamotrigine, Carbamazepine, Phenytoin, Phenobarbitone), Allopurinol at doses above 100 mg per day, and sulphonamides (e.g., Cotrimoxazole, Sulfasalazine). Genetic predispositions, particularly the presence of the HLA-B*1502 allele, significantly increase the risk of developing SJS. This case report discusses a unique presentation of SJS in a young female patient, emphasizing the critical need for genetic screening and careful monitoring when prescribing Carbamazepine, especially in populations at higher genetic risk. Case Presentation: A 19-year-old female patient, who had been on Phenytoin and Sodium Valproate for epilepsy management over the past year, was newly prescribed Carbamazepine. Within a week of initiating Carbamazepine, the patient experienced a seizure, followed by the sudden onset of fever, painful sores, and blisters covering the upper body, along with mucous discharge from both eyes. These symptoms rapidly worsened. Based on clinical presentations and the extent of epidermal detachment, the patient was diagnosed with SJS. The severity and mortality risks were assessed using the SCORTEN score. Therapeutic interventions included intravenous Ranitidine, Ondansetron, Paracetamol, Midazolam, Levetiracetam, and Dexamethasone, along with oral Fluconazole, Chlorpheniramine tablets, and Ciprofloxacin eye drops. The patient showed significant improvement and was discharged after fourteen days with followup advice. Conclusion: This case underscores the critical importance of performing genetic testing for the HLA-B*1502 allele and conducting baseline blood tests before initiating Carbamazepine therapy. Such precautionary measures can significantly mitigate the risk of severe adverse reactions like SJS. This report adds to the scientific literature by highlighting the potential dangers associated with anticonvulsant therapies and the necessity for personalized medicine approaches in preventing life-threatening conditions. The main takeaway is the pivotal role of genetic screening and vigilant monitoring in the management of patients requiring anticonvulsant medications to prevent serious adverse reactions.

Cardiovascular diseases (CVDs) remain the leading cause of global mortality, necessitating effective preventive and adjunct therapeutic strategies beyond conventional pharmacological interventions. Although previous reviews have focused on individual nutrients or dietary patterns, this review provides a mechanism‐based, integrative perspective on food‐grade proteins, lipids, and dietary fibers in CVDs. Here, food‐grade refers to nutritionally safe, regulatory‐compliant macronutrients incorporated into functional foods with defined physiological benefits. This review evaluates how these macronutrients target key CVD pathways. Food‐grade proteins release bioactive peptides with ACE‐inhibitory, lipid‐lowering, and endothelial‐protective effects. Functional lipids, particularly omega‐3 fatty acids and phytosterols, regulate lipid metabolism, stabilize atherosclerotic plaques, and reduce inflammation. Soluble dietary fibers such as β‐glucan, psyllium, and pectin lower cholesterol absorption, improve glycemic control, and modulate gut microbiota. Importantly, this review highlights synergistic and antagonistic interactions among these macronutrients within real food matrices, emphasizing their combined influence on digestion, bioavailability, and metabolic responses. Dose–response relationships and practical intake considerations are also discussed to bridge mechanistic insights with dietary applications. Collectively, this framework positions food‐grade macronutrients as interactive modulators of cardiovascular health rather than isolated components. Future research should focus on validating nutrient interactions, optimizing synergistic formulations, and establishing clinically effective intake thresholds.
