Cerium-doped calcium carbonate microparticles combined with low-intensity ultrasound for efficient sonodynamic therapy in body sculpting

Excessive caloric intake and reduced energy expenditure contribute to obesity and localized fat accumulation, adversely affecting overall health. Despite advancements in obesity treatments, noninvasive approaches for targeted fat reduction remain limited. This study introduces a novel sonosensitizer microparticle, cerium-doped calcium carbonate (CaCO3:Ce), and evaluates its potential application in combination with low-intensity ultrasound (LIUS) for noninvasive body sculpting. CaCO3:Ce was synthesized via an environmentally friendly method, producing uniform 1.77 μm particles optimized for endocytosis. Energy-dispersive X-ray and X-ray photoelectron spectroscopy confirmed successful cerium doping. The particles demonstrated excellent biocompatibility and generated reactive oxygen species under LIUS exposure. Safety was validated through biochemical, hematological, and histological analyses in Sprague-Dawley rats. Animal experiments further revealed that CaCO3:Ce combined with ultrasound significantly reduced body weight growth rates, waistline measurements, and subcutaneous fat accumulation. These findings suggest that CaCO3:Ce, coupled with LIUS, offers a promising, noninvasive, and low-risk strategy for body sculpting, addressing limitations of current methodologies.

The Price of Beauty: A Literature Review on Non-Tuberculous Mycobacteria Infection After Cosmetic Procedures

Non-tuberculous mycobacteria (NTM) infection of the skin and soft tissues is a complication of cosmetic procedures. The incidence of cutaneous NTM infections has increased significantly as aesthetic operations have become more commonplace. With the rise of cosmetic tourism, the geographic expansion of NTM infections is a major concern. Due to the unique pathogenesis of NTM infections, diagnosis and treatment remain significant challenges for clinicians. Clinical management relies on a combination of antibiotic therapy with drug susceptibility testing and appropriate surgical debridement. Some new drugs, photodynamic therapy, and bacteriophage therapy have been developed in recent years, and may improve the aesthetic outcomes. This review summarizes the cosmetic procedures prone to NTM infections in recent years and their clinical features. We propose a 2-stage treatment procedure, including a hospitalization phase and a follow-up phase. We aim to increase the alertness of clinicians to NTM infections for timely detection and treatment.

Iatrogenic Liver Perforation During Liposuction: A Case Report and In-depth Review of Clinical Presentation, Management, and Lessons Learned

Liposuction is generally recognized as a safe medical procedure. However, it is important to acknowledge the potential for complications during and after the operation. Although rare, the occurrence of iatrogenic liver perforation following liposuction is viewed as a serious complication, necessitating immediate and attentive medical care. We report a case of a 42-year-old female who underwent liposuction and presented with abdominal pain 3 days later. Elevated liver enzymes and imaging revealed an active bile leak from the right liver lobe. Exploratory laparotomy confirmed a penetrating injury, leading to multiple washout surgeries. After a 3-month hospital stay, including intensive care, the patient fully recovered upon discharge following abdominal wound closure. Despite considering liposuction procedures safe due to the associated overall low risk rates, it can lead to life-threatening complications such as hollow viscus or solid organ injury. The treatment for such complications can either be surgical or nonsurgical, depending on the patient's presentation and diagnosis. To promptly identify and address any complication postsurgery, close monitoring of patients postoperatively is necessary.
