Inflammatory bowel disease (IBD) is a chronic gastrointestinal inflammatory disorder with two main subtypes: ulcerative colitis (UC) and Crohn’s disease (CD). The pathogenesis involves genetic predisposition, dysbiosis, and immune dysregulation. Complications include perianal lesions, strictures, fistulas, perforations, and an increased risk of colon cancer. Clinical classification ranges from mild to fulminant and recurrent disease, with common symptoms such as abdominal discomfort, rectal bleeding, diarrhea, and weight loss. Extraintestinal manifestations include arthritis, erythema nodosum, pyoderma gangrenosum, and uveitis. Conventional treatments using aminosalicylates, corticosteroids, and immunomodulators have limitations. Biologics, introduced in the 1990s, offer improved efficacy and specificity, targeting factors like TNF-α, integrins, and cytokines. Monoclonal antibodies play a crucial role in IBD management, aiming to reduce relapses, hospitalizations, and surgeries. In conclusion, this review is aimed at summarizing the latest knowledge, advantages, and drawbacks of IBD therapies, such as small molecules, biologics, and monoclonal antibodies, to provide a basis for further research in the IBD field.

This work proposes a methodological approach that could be useful in multidisciplinary health technology assessments (HTAs). Mathematical models based on real data were used to make predictions for the initial price and actual cost of three classes of biological drugs. Through a comparison of real data, with the data derived through this approach, degree coefficients were formulated to rank the negotiating capabilities of Italian regions. The proposed method could represent a valid means of support for healthcare decisionmakers in planning and reducing pharmaceutical spending, evaluating data, and finding uses for particular medical technologies. This study could be a useful tool for achieving the objectives of HTAs, providing a means of analysis that can be adapted to any data, which may be useful for rationalizing the use of health technologies, reducing waste, and optimally reallocating resources.

Objectives: Bone defects, resulting from many causes, represent a challenge in maxillofacial and orthopedic surgery. Regenerative medicine offers promising strategies by introducing exogenous materials to modify the tissue environment and modulate the body’s natural healing mechanisms. Dental pulp stem cells (DPSCs) are considered an effective source for tissue repair. Small molecules such as caffeic acid phenethyl ester (CAPE), although having promising effects in promoting bone regeneration, are characterized by low chemical stability, which impairs their clinical application. This study aimed to investigate the bone regenerative capability of four CAPE derivatives, recently synthesized in our laboratory and selected based on previous studies. Methods: DPSCs were induced to osteogenic differentiation in the presence of these compounds (0–5 μM), and cell viability, matrix deposition, alkaline phosphatase activity, and osteogenic marker gene expression were evaluated. In addition, bone biomaterials composed of a chitosan/agarose matrix reinforced with nanohydroxyapatite and enriched with these CAPE derivatives were fabricated and assessed for cytotoxicity and cell adhesion. Results: Two of the tested compounds effectively enhanced DPSC differentiation toward the osteogenic lineage. The fabricated bone biomaterials showed no cytotoxicity and supported cell adhesion. Furthermore, these compounds demonstrated stability under various conditions, confirming their suitability for incorporation into bone biomaterials. Conclusions: The tested CAPE derivatives exhibit promising osteoinductive properties and stability, offering a valid alternative to traditional therapeutic strategies in regenerative medicine.
