J Hand Ther 2024:S0894-1130(24)00005-X. [PMID: 38453574 DOI: 10.1016/j.jht.2024.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 01/12/2024] [Accepted: 02/09/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND Cubital tunnel syndrome (CBTS) impairs hand function, with limited conservative options often leading to surgery. Chitosan neuroregenerative effects delivered via phonophoresis provide a rationale for testing this emerging treatment approach. PURPOSE The primary goal of this research was to assess the impact of chitosan phonophoresis on the conductivity of the ulnar nerve, as well as its effects on pain levels and functional outcomes in individuals diagnosed with mild to moderate CBTS. STUDY DESIGN Double-blind randomized controlled trial. METHODS This was a prospective, double-blinded, randomized controlled study. The participants consisted of 54 individuals aged between 20-35 years who were randomly assigned using block randomization. The control group (n = 27) received standard hand therapy alone, while the experimental group (n = 27) received both standard hand therapy and chitosan phonophoresis. Both groups underwent three treatment sessions per week, each lasting for 60-72 minutes, over a period of five weeks. Pre- and post-intervention evaluations included assessments of ulnar nerve conduction velocity (NCV), pain assessment using the numerical pain rating scale (NPRS), as well as hand function evaluated using the Quick Disabilities of Arm Shoulder Hand (QuickDASH) questionnaire. RESULTS After the intervention, the experimental group significantly improved in all outcome measures compared to the control group. Accordingly, ulnar NCV (MD = 2.233 m/sec; CI = 1.63:2.83; p < 0.001; η2p = 0.516), NPRS (MD = -1.11; CI = -1.71: -0.50; p < 0.001; η2p = 0.208) and QuickDASH (MD = -2.72; CI = -4.54:0.87; p < 0.007; η2p = 0.133). CONCLUSIONS The study findings suggest that chitosan phonophoresis may have the potential as a supplementary treatment to hand therapy for individuals with mild to moderate CBTS. This approach demonstrated significant improvements in nerve conduction, pain reduction, and enhancement of hand function.

Abstract
Methods for creating various 3D morphologies of composites based on chitosan and copper nanoparticles stabilized by it in carbonic acid solutions formed under high pressure of saturating CO2 were developed. This work includes a comprehensive analysis of the regularities of copper nanoparticles stabilization and reduction with chitosan, studied by IR and UV-vis spectroscopies, XPS, TEM and rheology. Chitosan can partially reduce Cu2+ ions in aqueous solutions to small-sized, spherical copper nanoparticles with a low degree of polydispersity; the process is accompanied by the formation of an elastic polymer hydrogel. The resulting composites demonstrate antimicrobial activity against both fungi and bacteria. Exposing the hydrogels to the mixture of He or H2 gases and CO2 fluid under high pressure makes it possible to increase the porosity of hydrogels significantly, as well as decrease their pore size. Composite capsules show sufficient resistance to various conditions and reusable catalytic activity in the reduction of nitrobenzene to aniline reaction. The relative simplicity of the proposed method and at the same time its profound advantages (such as environmental friendliness, extra purity) indicate an interesting role of this study for various applications of materials based on chitosan and metals.

Abstract
This research includes production of chitosan nanocapsules through ionic gelation with sodium bisulfate for nanoencapsulation of hydroxytyrosol (HT) using ultrasonication in tandem. The resulting nanocapsules encapsulating HT were analyzed for particle size, ζ-potential, packaging characteristics, FESEM, ATR-FTIR, XRD, DSC, in vitro release, antioxidant potential and antiproliferative properties. The nanocapsules (size 119.50-365.21 nm) were spherical to irregular shaped with positive ζ-potential (17.50-18.09 mV). The encapsulation efficiency of 5 mg/g HT (HTS1) and 20 mg/g HT (HTS2) was 77.13% and 56.30%, respectively. The nanocapsules were amorphous in nature with 12.34% to 15.48% crystallinity and crystallite size between 20 nm and 27 nm. Formation of nanocapsules resulted in increasing the glass transition temperature. HTS2 delivered 67.12% HT (HTS1 58.89%) at the end of the simulated gastrointestinal digestion. The nanoencapsulated HT showed higher antioxidant and antiproliferative (against A549 and MDA-MB-231 cancer cell lines) properties than the free HT.

Abstract
Diabetes mellitus continues to be one of the most common diseases often associated with diabetic ulcers. Chitosan is an attractive biopolymer for wound healing due to its biodegradability, biocompatibility, mucoadhesiveness, low toxicity, and hemostatic effect. A panel of hydrogels based on chitosan, collagen, and silver nanoparticels were produced to treat diabetic wounds. The antibacterial activity, cytotoxicity, swelling, rheological properties, and longitudinal sections of hydrogels were studied. The ability of the gels for wound healing was studied in CD1 mice with alloxan-induced diabetes. Application of the gels resulted in an increase in VEGF, TGF-b1, IL-1b, and TIMP1 gene expression and earlier wound closure in a comparison with control untreated wounds. All gels increased collagen deposition, hair follicle repair, and sebaceous glands formation. The results of these tests show that the obtained hydrogels have good mechanical properties and biological activity and have potential applications in the field of wound healing. However, clinical studies are required to compare the efficacy of the gels as animal models do not reproduce full diabetes pathology.
