Background: Osteoarthritis is an incurable, progressive, degenerative and debilitating joint disease, characterized by pain, stiffness and limitation of joint mobility. Treatment is limited to symptom management and includes pharmaco- and physiotherapy, rehabilitation and surgery.
Objective: To evaluate safety and effectiveness of a selected hyaluronic acid injectable in the treatment of small joint osteoarthritis.
Materials And Methods: 324 patients (F: 190, M: 134) aged 19-84 completed the study. Each participant received three, weekly intra-articular hyaluronic acid injections (Suplasyn®, Bioniche Life Sciences Inc, Belleville, Ontario; 700 kDa, 7 ml/7 mg). Morning stiffness and pain intensity (at rest and movement-induced) before and after treatment as well as post-treatment improvement in joint mobility were assessed based on questionnaires filled out by patients and their physicians prior to treatment commencement and at its conclusion. Participants used a Numerical Rating Scale (range 0-10 points) to quantify assessments. Data was analysed with chi-square and Fisher's exact tests and p = 0.05 was accepted as significant.
Results: A significant (p <0.001) post-treatment reduction in (1) morning stiffness (median NRS score decrease from 6 to 2 points), (2) pain intensity at rest (median NRS score decrease from 5 to 2 points) and movement induced (median NRS value decrease from 6 to 2 points). Improvement in joint mobility was reported by 97% of patients. Treatment tolerability (safety) was assessed as good to excellent by 25 % and 74% of patients, respectively. No serious adverse reactions were reported.
Conclusion: Hyaluronic acid injections are a highly effective and safe treatment for symptomatic small joint osteoarthritis.

The use of combination therapies that employ a variety of cell death mechanisms has emerged as a promising avenue of research in the treatment of cancer. However, the optimization of therapeutic synergies when integrating different modes remains a significant challenge. To this end, we developed a multifunctional intelligent drug-carrying nanoparticle (DFMTCH NPs) based on the metal-organic framework MIL-100, loaded with doxorubicin (DOX) and disulfiram (DSF), coated with a Cu-tannic acid (Cu-TA) network and hyaluronic acid (HA), for the purpose of combined chemotherapy/chemodynamic/photothermal anti-cancer therapy.

Oral ulcer wounds are difficult to heal due to bacterial infections, persistent inflammatory responses, and excessive reactive oxygen species (ROS). Therefore, the elimination of bacteria, removal of ROS, and reduction of inflammation are prerequisites for the treatment of mouth ulcer wounds. In this study, oligomeric proanthocyanidins (OPC) and 3-(aminomethyl)phenylboronic acid-modified hyaluronic acid (HP) were used to form polymer gels through dynamic covalent borate bonds.

Background: Deepening of the nasolabial fold (NLF), drooping of the nasal tip, and facial expressions perceived as angry face, are common esthetic concerns. However, no studies have correlated this set of signs and symptoms with common anatomical causes. We review anatomical considerations of the region and propose a combined treatment modality.

Osteoarthritis (OA) presents a significant therapeutic challenge, with few options for preserving joint cartilage and repairing associated tissue damage. Inflammation is a pivotal factor in OA-induced cartilage deterioration and synovial inflammation. Recently, exosomes derived from human umbilical cord mesenchymal stem cells (HucMSCs) have gained recognition as a promising noncellular therapeutic modality, but their use is hindered by the challenge of harvesting a sufficient number of exosomes with effective therapeutic efficacy.

Inspired by natural microbial cooperation, a co-culture approach was used to synthesize bacterial nanocellulose (BNC)-based nanocomposites for potential wound healing applications. By co-culturing either Komagataeibacter xylinus (K1G4) or the never tested strain K. rhaeticus (K2G46) with the hyaluronic acid (HA)-producer Lacticaseibacillus casei UMCC 2535, two BNC-HA nanocomposites were obtained (C1-K1 and C2-K2).
