Objectives: Facial lipoatrophy can be a stigmatizing side effect of antiretroviral (AVR) treatment for HIV-infected patients. We sought to evaluate the long-term efficacy and safety of a new formulation of hyaluronic acid that can be injected in larger amounts and into deeper skin layers during 3 years of follow-up.
Methods: Twenty patients received injections of Restylane SubQ(). Refill treatment was offered at 12 and 24 months. Treatment effects were evaluated using ultrasound, the Global Aesthetic Improvement Scale, visual analogue scale (VAS) and the Rosenberg self-esteem scale.
Results: Seventeen patients remained at 36 months. Mean (+/- standard deviation) total cutaneous thickness increased from 6 +/- 1 mm at baseline to 12 +/- 1 mm (P<0.001) at 36 months. Response rate (total cutaneous thickness >10 mm) was 70%. Fifteen patients classified their facial appearance as very much or moderately improved. VAS increased from 39 +/- 25 to 70 +/- 20 (P<0.05) and higher self-esteem scores were reported. Local swelling and tenderness after treatment was common. Persistent papules found in several patients after treatment were removed effectively with hyaluronidase injections. Three patients, treated only at baseline, still had higher total cutaneous thickness scores at 36 months.
Conclusions: Our results indicate that a large particle hyaluronic acid formulation is a durable and well-tolerated dermal filler for treating HIV-positive patients with facial lipoatrophy.

Accurate discrimination of complicated glycosaminoglycans is a challenging but meaningful task for ensuring their safe use in clinics. With the purpose of reducing the production cost of sensor arrays for glycosaminoglycans, three fluorescence turn-on sensors named , , and were readily synthesized by simple alkylation of the pyridyl units of the π-extended AIEgen, namely, tetra-(4-pyridylphenyl) ethylene. The designed sensors are cross-reactive toward tested glycosaminoglycans including heparin, chondroitin sulfate, hyaluronic acid, and dextran sulfate, whose mechanism could be ascribed to the multivalent electrostatic, CH···π, and hydrophobic interactions between the sensors and different glycosaminoglycans to form corresponding fluorescent aggregates.

Wound healing is a complex and dynamic biological process that requires meticulous management to ensure optimal outcomes. Traditional wound dressings, such as gauze and bandages, although commonly used, often fall short in their frequent need for replacement, lack of real-time monitoring and absence of anti-inflammatory and antibacterial properties, which can lead to increased risk of infection and delayed healing. Here, we address these limitations by introducing an innovative hydrogel dressing, named PHDNN6, to combine wireless Bluetooth temperature monitoring and light-triggered nitric oxide (NO) release to enhance wound healing and management.

Introduction: Owing to its high prevalence, colossal potential of chemoresistance, metastasis, and relapse, breast cancer (BC) is the second leading cause of cancer-related fatalities in women. Several treatments (eg, chemotherapy, surgery, radiations, hormonal therapy, etc.) are conventionally prescribed for the treatment of BC; however, these are associated with serious systemic aftermaths.

Superparamagnetic iron oxide nanoparticles (SPIONs) are known to be good MRI contrasts, but they have a high tendency to aggregate and their biocompatibility is limited. Hyaluronic acid is highly biocompatible, can provide SPION with colloidal stability, and interacts specifically with tumor cells through the CD44 receptor; therefore, it was used as a stabilizing layer. We successfully obtained SPION coated with hyaluronic acid and further functionalized it with folic acid to construct a dual-targeted system.
