Adjunctive Perioperative Host-Resilience and Gram-Negative Endotoxin Modulation: A Hypothesis-Generating Translational Framework

The Sandeep Ghadge Framework (SGF) is a hypothesis-generating translational model that integrates three interconnected domains relevant to Gram-negative postoperative sepsis: pathogen pressure reduction, host-resilience optimization, and investigation of endotoxin-mediated inflammatory amplification. Drawing upon established literature in sepsis biology, lipopolysaccharide (LPS) signaling, immunology, nutritional science, and lactoferrin biology, the framework proposes a unified three-axis approach for understanding host-pathogen interactions in severe Gram-negative infection.

The manuscript does not propose a new standard of care or therapeutic recommendation. Instead, it presents a conceptual framework designed to generate testable scientific hypotheses and guide future mechanistic studies, biomarker investigations, observational research, and pilot feasibility trials. Particular emphasis is placed on the potential roles of vitamin D status, zinc status, and lactoferrin-endotoxin interactions as investigational components within a broader host-response model.

The novelty of the SGF lies not in the individual biological mechanisms discussed, but in their integration into a structured translational framework linking microbial burden, host resilience, and endotoxin-associated inflammatory processes. The framework is intended to stimulate scientific discussion and provide a foundation for future research aimed at improving understanding of Gram-negative postoperative sepsis and host-response biology.
