1. Enzyme-Mediated Dynamic Combinatorial Chemistry Enables Large-Scale Synthesis of δ-Cyclodextrin.
This paper establishes the first scalable, high-yield (>40%) and high-purity (>95% without chromatography) synthesis of δ-cyclodextrin (nine glucose units) using enzyme-mediated dynamic combinatorial chemistry and a dodecaborate template. The method enables multigram production, unlocking applications in cosmetics and pharmaceuticals for encapsulating actives, improving stability, and controlled release.
Impact: By overcoming a long-standing scalability barrier, this work provides a foundational excipient platform with direct translational potential in cosmeceutical and pharmaceutical formulation science.
Clinical Implications: While not a clinical study, δ-cyclodextrin may enable safer and more effective topical/cosmeceutical products via improved solubilization and stabilization of active ingredients; toxicology and dermal safety testing will be required before clinical use.
Key Findings
- Introduces a scalable synthesis of δ-cyclodextrin with >40% yield and >95% purity without chromatography
- Achieves multigram quantities using enzyme-mediated dynamic combinatorial chemistry and a dodecaborate template
- Positions δ-CD for applications as a host carrier in foods, cosmetics, and pharmaceuticals
Methodological Strengths
- Template-directed dynamic combinatorial chemistry enabling selectivity and scalability
- High-purity product without chromatographic purification, enhancing manufacturability
Limitations
- Lacks pharmacokinetic/toxicological data for dermal or systemic exposure
- Industrial cost and environmental impact of the superchaotropic template are not evaluated
Future Directions: Evaluate δ-CD toxicology, dermal compatibility, and performance as a carrier for cosmetic actives; scale-up beyond multigram and lifecycle assessments to support regulatory adoption.
α-, β-, and γ-cyclodextrins (CDs) are macrocycles formed from six, seven, and eight α-1,4-linked d-glucopyranose units and are industrially produced on ton scales for use as hosts for bioactive guests in foods, cosmetics, and pharmaceuticals. Large-ring cyclodextrins, with more than eight glucose units, have been known for decades but never isolated in more than milligram quantities. We report a scalable method to synthesize δ-CD, formed from nine glucose units, in high yield (>40%), high purity (>95% purity without chromatography), and unprecedented quantities (multigram scale). We exploit a superchaotropic dodecaborate template, B
2. Ultrasound-Guided Gluteal Fat Grafting: What is the Evidence? A Systematic Review and Meta-Analysis.
Across 6,235 patients, ultrasound-guided gluteal fat grafting demonstrated no reported mortality or fat embolism and low rates of minor complications. These findings support ultrasound guidance as a safer technique that aligns with recommendations to avoid intramuscular injection.
Impact: Addresses an urgent safety issue in a high-demand cosmetic procedure by quantifying serious adverse events and minor complication rates with ultrasound guidance.
Clinical Implications: Clinicians should adopt ultrasound guidance for gluteal fat grafting, emphasize subcutaneous-only injections, and integrate training/credentialing to reduce catastrophic complications.
Key Findings
- No reported mortality or fat embolism across 6,235 patients undergoing ultrasound-guided gluteal fat grafting
- Low pooled minor complication rate (6.32 per 100), including seroma (2.94/100), infection (0.23/100), and fat necrosis (0.09/100)
- Use of Freeman–Tukey transformation and R-based meta-analysis with low heterogeneity (I² = 0 for fat necrosis)
Methodological Strengths
- Systematic search across multiple databases with quantitative meta-analysis
- Clear reporting of pooled rates with confidence intervals and use of appropriate transformations
Limitations
- Only four studies included and all patients were female, limiting generalizability
- Observational evidence with potential underreporting and lack of long-term follow-up
Future Directions: Prospective registries and standardized ultrasound protocols with competency benchmarks; assessment of long-term outcomes and cost-effectiveness.
Buttock augmentation has become one of the most sought-after cosmetic procedures, but concerns over fat embolism-related fatalities have raised significant safety issues. Guidelines emphasize that fat grafting should remain in the subcutaneous layer, avoiding intramuscular injection. This systematic review and meta-analysis assess the efficacy and safety of ultrasound-guided gluteal fat grafting. A systematic search of PubMed, Cochrane Central Register of Controlled Trials, and Embase was conducted until July 2024, analyzing patient satisfaction, complication rates, mortality, fat embolism, fat necrosis, infection, and seroma. Statistical analyses, including the Freeman-Tukey Double Arcsine Transformation, were performed using R version 4.1.2. Four studies with a total of 6,235 female patients (mean age 34 years, BMI 30.1 kg/m²) met the inclusion criteria. The pooled analysis showed no reported mortality (0.00 per 100, 95% CI: 0.00-0.00) or fat embolism (0.00 per 100, 95% CI: 0.00-0.00). Minor complications occurred at a rate of 6.32 per 100 (95% CI: 3.23-10.27), with seroma at 2.94 per 100 (95% CI: 0.97-5.75), infection at 0.23 per 100 (95% CI: 0.00-0.96), and fat necrosis at 0.09 per 100 (95% CI: 0.01-0.23; I² = 0). The findings indicate that ultrasound-guided gluteal fat grafting is associated with low complication rates and no reported serious adverse events such as death or fat embolism, reinforcing its role as a safer technique for buttock augmentation.
3. Prevalence of Body Dysmorphic Disorder: A Systematic Review and Meta-Analysis.
This systematic review and meta-analysis reports a high prevalence of BDD, including 24% among plastic surgery patients and 17% in the general population, with higher rates in females and in Latin America. Findings underscore the need for routine BDD screening in aesthetic and dermatologic settings.
Impact: Quantifying BDD burden across settings provides essential evidence to integrate mental health screening and referral into cosmetic practice, improving patient safety and outcomes.
Clinical Implications: Implement validated screening (e.g., BDDQ) before aesthetic procedures; avoid interventions in severe BDD; establish referral pathways to mental health services and inform consent discussions.
Key Findings
- Overall BDD prevalence estimated at 17% in the general population and 24% among plastic surgery patients
- Higher prevalence in females than males and regional variation with highest rates in Latin America
- Systematic approach using multiple databases, R-based meta-analysis, and JBI critical appraisal
Methodological Strengths
- Comprehensive search across multiple databases with predefined inclusion criteria
- Use of standardized bias assessment (JBI) and statistical synthesis
Limitations
- Marked heterogeneity likely due to differing diagnostic tools and cross-sectional designs
- Potential overestimation/selection bias in cosmetic clinic samples; limited longitudinal data
Future Directions: Standardize BDD diagnostic instruments across studies and evaluate screening-to-outcome pathways in aesthetic clinics including stepped-care interventions.
BACKGROUND: Body dysmorphic disorder (BDD) is characterized by a preoccupation with ≥ 1 perceived defects in physical appearance, which leads to social anxiety and avoidance. This excessive focus on appearance is linked to dissatisfaction with physical features, disappointment with cosmetic treatments, or frustration from not meeting perceived beauty standards. OBJECTIVE: The aim of this study was to determine the prevalence of BDD in dermatology, psychiatric, plastic surgery, general population, and world regions, as well as the prevalence of BDD using different diagnostic tools. METHODS: The authors conducted a systematic review of the literature in Medline via PubMed, Embase, and Latin American databases using MeSH terms "body dysmorphic disorder" and "prevalence" with filters for original and cross-sectional studies. Statistical analysis was performed using RStudio, and bias assessment was made using JBI Critical appraisal. RESULTS: The overall prevalence of BDD in the general population was 17%, with higher rates in females than in males. The prevalence in plastic surgery patients was 24%. The highest prevalence of BDD was found in Latin America compared to other world regions. CONCLUSIONS: BDD is a highly prevalent disorder, and increased awareness of the disease could improve its approach in plastic surgery and other medical fields.
