Background: Objective: Seroma formation is plaguing complication in abdominal body contouring surgery (ABCS) that has been loosely associated with the use of intraoperative hemostatic agents. The aim of this study was to investigate the association between hemostatic agent usage and seroma development following ABCS.
Methods: A retrospective review of patients undergoing ABCS between 2010 and 2020 was completed. Cases who received hemostatic agents were matched to controls (1:2) based on potential confounders including age, BMI, and ASA score. Demographic data, operative details, and postoperative complications including development of seroma, hematoma, venous thromboembolism, wound dehiscence, and delayed wound healing were collected.
Results: Seven hundred and seven patients were included in the study. Sixty-five patients (9.2%) received at least one hemostatic agent. The most used agents were topical thrombin (n = 33, 50.1%), dry matrices including oxidized cellulose, microporous polysaccharides, and absorbable gelatin matrices (n = 15, 23.1%) followed by combination fibrin sealant/thrombin preparations (n = 9, 14.0%). No significant differences with respect to demographic data or medical comorbidities between the cases and controls were identified. Bivariate analysis demonstrated no significant differences in the rate of development of seroma (OR: 0.83, 95% confidence interval [CI] = 0.23-1.99, p = 0.781), hematoma (OR: 3.72, 95% confidence interval [CI] = 0.95-14.65, p = 0.060), venous thromboembolism (OR: 0.40, 95% confidence interval [CI] = 0.44-3.81, p = 0.433).
Conclusion: Hemostatic agent use, regardless of type, does not significantly affect the risk of seroma, hematoma, and venous thromboembolism development, nor does it influence the rates of delayed wound healing or wound dehiscence.

Next-generation wound dressings with multiple biological functions hold promise for addressing the complications and pain associated with burn wounds. A hydrogel wound dressing loaded with a pain-relieving drug was developed for treating infected burn wounds. Polyvinyl alcohol chemically grafted with gallic acid (PVA-GA), sodium alginate chemically grafted with 3-aminobenzeneboronic acid (SA-PBA), Zn, and chitosan-coated borneol nanoparticles with anti-inflammatory and pain-relieving activities were combined to afford a nanoparticle-loaded hydrogel with a PVA-GA/Zn/SA-PBA network crosslinked via multiple physicochemical interactions.

Objectives: Depth of invasion (DOI) in oral squamous cell carcinoma (OSCC) guides treatment and prognosis but lacks three-dimensional (3D) insight. Thus, this study aimed to investigate the feasibility and accuracy of Lugol's iodine-enhanced micro-computed tomography (CT) for the 3D measurement of DOI in OSCC samples.
Methodology: In total, 50 in vitro OSCC samples from Nanjing Stomatological Hospital (July 2022 to January 2024) were subjected to micro-CT imaging with a slice thickness of 50 μm following 3% Lugol iodine staining for 12 h, followed by pathological examination and staining.

Although traditional petroleum-based packaging materials pose environmental problems, biodegradable packaging materials have attracted extensive attention from research and industry for their environmentally friendly properties. Bio-based films, as an alternative to petroleum-based packaging films, demonstrate their significant advantages in terms of environmental friendliness and resource sustainability. This paper provides an insight into the development of biomass food packaging films such as cellulose, starch, chitosan, and gelatine, including their properties, methods of preparation (e.
