Summary
Three impactful studies span surgical outcomes, skin microbiome modeling, and objective aesthetic assessment. A large matched cohort links preexisting anxiety/depression to higher wound complications after breast reduction. An ex vivo perfused human skin model preserves donor-specific microbiota for dermo-cosmetic testing, while an AI-enabled, multimodal imaging study quantifies pore improvement after microneedling with adipose-derived exosomes.

1. Preexisting Depression or Anxiety is Associated with Increased Wound Complications Following Breast Reduction Surgery: A Real-World Cohort Study.
In a matched retrospective cohort of 31,692 women undergoing breast reduction, preexisting anxiety/depression was associated with higher risks of wound complications, infections, reinterventions, and opioid use at 30–90 days, with signals persisting to 1 year. Findings suggest psychological comorbidity is an independent risk factor despite propensity matching.
Impact: Establishes a robust, generalizable association between preexisting mental health disorders and postoperative wound risk in a common aesthetic surgery, supporting integrated perioperative mental health care.
Clinical Implications: Implement routine preoperative screening for anxiety/depression, optimize mental health prehabilitation, set realistic expectations, and intensify postoperative wound surveillance and infection prevention. Anticipate higher analgesic needs and plan opioid-sparing strategies.
Key Findings
- After 1:1 propensity score matching (n=15,846 per cohort), ADD was associated with higher 30-day risks: seroma (RR 1.895), hematoma (RR 1.508), wound dehiscence (RR 1.33), and surgical site infection (RR 1.495).
- ADD was linked to increased 30-day opioid use (RR 1.291), inpatient hospitalization (RR 1.77), and readmission (RR 1.857).
- Risk elevations persisted at 60 and 90 days and were comparable at 1 year, indicating durable associations beyond the immediate postoperative period.
Methodological Strengths
- Large real-world dataset with rigorous 1:1 propensity score matching to balance baseline covariates.
- Multiple clinically relevant endpoints assessed across 30/60/90 days and 1 year.
Limitations
- Retrospective design with potential residual confounding and diagnostic misclassification.
- Limited granularity on surgical technique, perioperative management, and adherence behaviors.
Future Directions: Prospective trials to test preoperative mental health optimization pathways; mechanistic studies on stress biology, sleep, and adherence mediating wound healing risks.
BACKGROUND: Breast reduction surgery is the primary treatment for macromastia, yet the impact of preexisting anxiety and depressive disorders (ADD) in candidates for this procedure has not been thoroughly investigated. This study aimed to evaluate the association between preexisting ADD and the incidence of both short-term and long-term complications after breast reduction surgery. METHODS: This retrospective cohort study used data obtained from the Tr
2. Development of an ex vivo skin model for quantitative recovery and preservation of donor-specific human microbiota.
A perfused human skin explant platform enables transfer and 48-hour preservation of donor-specific microbiota with maintained alpha-diversity and donor-clustered beta-diversity. Tissue architecture remained intact, and innate immune markers were modulated, offering a controlled, human-relevant testbed for microbiome-targeted dermo-cosmetic and therapeutic evaluations.
Impact: Introduces a physiologically relevant ex vivo human skin model that preserves donor-specific microbial communities, bridging a critical gap between in vitro simplicity and in vivo complexity for dermo-cosmetic R&D.
Clinical Implications: Preclinical screening of microbiome-friendly cosmetics and therapeutics can be performed on human tissue while retaining donor signatures, potentially improving translation and reducing reliance on animal models.
Key Findings
- Alpha-diversity showed no significant differences between original and transferred microbiota at genus level; donor-specific signatures persisted at 48 hours.
- Beta-diversity (Bray-Curtis) clustered by donor; controls formed separate clusters, indicating minimal background and cross-contamination.
- Histology preserved tissue architecture; immunostaining showed modulation of innate immune markers consistent with localized skin response.
Methodological Strengths
- Integrated qPCR, 16S rRNA sequencing, histology, and immunostaining within a controlled perfused explant system.
- Donor-matched transfer with appropriate controls enabling discrimination of endogenous vs transferred microbiota.
Limitations
- Short-term culture (48 hours) and small number of donors limit generalizability.
- Lacks functional metagenomics and longer-term stability or in vivo validation.
Future Directions: Extend culture duration and donor numbers; incorporate shotgun metagenomics/metatranscriptomics; test dermo-cosmetic actives and probiotics; correlate ex vivo shifts with clinical outcomes.
BACKGROUND: Through multi-omics approaches, our understanding of skin microbiota has substantially advanced. However, the development of reliable and physiologically relevant experimental models would greatly accelerate progress in microbiome-targeted science. Most investigations of skin microbiota rely on in vitro 2D models or reconstructed epidermis colonized with a limited number of strains, which do not reflect the complexity and the spatial micr
3. Artificial Intelligence-assisted Multimodal Quantification of Facial Pore Reduction After Microneedling With Adipose-derived Stem Cell Exosomes.
Thirty participants underwent three sessions of microneedling with topical adipose-derived stem cell exosomes and were evaluated by 3D imaging, surface roughness mapping, and AI-based segmentation. All modalities showed significant improvements in pore-related metrics and texture, demonstrating convergent, objective outcome assessment.
Impact: Pioneers an AI-enabled, multimodal framework to objectively quantify pore and texture changes after a popular cosmetic procedure, addressing a key measurement gap.
Clinical Implications: Facilitates standardized, device-agnostic outcome tracking for pore treatments; supports patient counseling, objective benchmarking, and future trial endpoints.
Key Findings
- QuantifiCare 3D regional pore scores improved significantly across all six facial zones following three treatment sessions.
- Gwyddion-based 3D surface roughness metrics decreased, indicating smoother skin topography post-treatment.
- AI-assisted image segmentation demonstrated reductions in pore area/number, aligning with imaging and roughness analyses.
Methodological Strengths
- Triangulation across three independent, quantitative platforms (3D imaging, surface roughness, AI segmentation).
- Standardized, high-resolution imaging under controlled lighting and positioning.
Limitations
- Single-arm prospective design without a control or comparator limits causal inference.
- Small sample size (n=30) and limited reporting of detailed statistics and durability.
Future Directions: Randomized trials comparing microneedling with vs without exosomes; dose-response and durability studies; validation of AI metrics as surrogate endpoints.
BACKGROUND: Enlarged facial pores are a common cosmetic concern, exacerbated by age-related collagen degradation and sebaceous hyperactivity. Despite clinical demand, objective quantification methods for pore improvement remain limited. This study used 3 independent analytical platforms-QuantifiCare 3-dimensional (3D) imaging, Gwyddion-based surface roughness analysis, and artificial intelligence (AI)-assisted image segmentation-to evaluate the efficac
