1. Next-generation full-thickness human skin models produced using 3D electrospun scaffolds and animal-component-free culture media.
The authors developed full-thickness human skin models using electrospun stromal scaffolds and animal-component-free media, eliminating animal collagen, FBS, and BPE. The models demonstrated improved lifespan, enhanced barrier properties, and reproducibility within and across batches, validated in two independent laboratories.
Impact: This platform addresses reproducibility and ethical limitations of current skin models, enabling animal-product-free, scalable testing for cosmetics and chemicals. Cross-lab validation strengthens translational utility.
Clinical Implications: Improved, animal-free FT-skin models can accelerate preclinical safety testing of cosmetic ingredients and chemicals, reduce reliance on animal testing, and enhance regulatory confidence through reproducible barrier function metrics.
Key Findings
- Electrospun scaffolds and animal-component-free media produced FT-skin with improved lifespan and barrier properties.
- Protocols showed intra- and inter-lot reproducibility across two independent laboratories, indicating transferability.
- Eliminating animal collagen, FBS, and BPE mitigated contraction/stability issues common to traditional models.
Methodological Strengths
- Validated across two independent laboratories demonstrating protocol transferability.
- Animal-component-free media and scaffolds reduce biological variability and ethical constraints.
Limitations
- Findings are based on in vitro models without direct in vivo correlation.
- Validation was limited to two laboratories; broader interlaboratory ring trials were not reported.
Future Directions: Expand interlaboratory ring trials, benchmark barrier metrics against in vivo skin, and adapt the platform to other epithelia (ocular, airway, intestine) for regulatory acceptance.
INTRODUCTION: In vitro full-thickness human skin (FT-Skin) models are important tools for testing of cosmetics and chemicals, screening of new pharmaceuticals, and human disease modeling research. However, these skin models commonly utilize animal-derived collagen as a main structural element of the stromal matrix. Animal-derived collagen constructs suffer from stability and contraction issues, resulting in short lifespan and poor reproducibility. Additionally, culture media utilized to produce these models commonly contain undesirable animal-derived components including fetal bovine serum (FBS) and bovine pituitary extract (BPE). METHODS: To address these shortcomings, FT-Skin models were developed without animal-derived collagen by using electrospun scaffolds as a structural component of the stromal constructs, together with FBS- and BPE-free culture media formulations. RESULTS: These novel culture protocols and media formulations produced well-developed FT-Skin models with improved lifespan and barrier properties. Protocol transferability, and intra- and inter-lot reproducibility of the FT-Skin models were demonstrated by testing in 2 independent laboratories. DISCUSSION: These next-generation FT-Skin models offer opportunities for completely animal-product-free testing of cosmetics and chemicals, screening of new pharmaceuticals and more human-relevant modeling of skin diseases. The electrospun scaffolds and basic processes for development of animal-free subepithelial stromal constructs are also anticipated to be adaptable to the development of additional epithelial tissue models such as ocular, airway and intestine.
2. Surgical site infections in the returning medical tourist: bridging the knowledge gap and identifying areas for improvement.
In a prospective multicenter cohort of 37 returning medical tourists with SSIs, 59% had positive cultures, predominantly Gram-negative (68% of positives). Notably, 77% of isolates were resistant to antimicrobials recommended by local empiric guidelines, highlighting the need to tailor empiric therapy to the surgical location and resistance patterns.
Impact: Provides concrete antimicrobial susceptibility data for a growing, high-risk cohort, directly informing revisions to empiric treatment pathways and surveillance strategies.
Clinical Implications: Clinicians should obtain detailed travel and surgical histories for post-tourism SSIs and broaden empiric coverage to include likely Gram-negative and resistant organisms, adjusting based on source-country resistance patterns.
Key Findings
- Among 37 patients, 59% had significant positive cultures; 68% of positives were Gram-negative organisms.
- In 77% of culture-positive cases, isolates were resistant to antimicrobials recommended by local empiric guidelines.
- Most surgeries were cosmetic (34/37) and commonly performed in Turkey (57%); abdominoplasty was the leading procedure (46%).
Methodological Strengths
- Prospective, multicenter design across four tertiary plastic surgery centers.
- Standardized CDC criteria for SSI classification and uniform data collection proforma.
Limitations
- Modest sample size (n=37) limits precision and subgroup analyses.
- Single-country setting may limit generalizability to other healthcare systems.
Future Directions: Develop international antibiograms for common destination countries, integrate travel-aware empiric pathways into guidelines, and conduct larger surveillance studies.
BACKGROUND: Medical tourism, particularly for cosmetic and bariatric procedures, has become increasingly common. This presents significant challenges when patients return to their home country with post-operative infections requiring management. Treatment guidelines for surgical site infections (SSIs) are typically based on local antimicrobial susceptibility patterns, which may not be appropriate when surgery was performed abroad, in countries with potentially differing antimicrobial resistance profiles and healthcare practices. AIM: To review the demographics, risk factors, surgical management, microbial aetiology and treatment of SSI in patients presenting to hospitals in Ireland after undergoing cosmetic or bariatric surgery abroad. METHODS: This prospective, multi-centre observational study was conducted across four tertiary referral plastic surgery centres in the Republic of Ireland. Ethical approval was obtained at each participating hospital site, and a standardised data collection proforma ensured consistency in reporting. SSIs were classified as per the Centres for Disease Control and Prevention (CDC) criteria. Eligible participants were adults presenting in the Republic of Ireland with infections after undergoing cosmetic or bariatric procedures abroad. Practising plastic surgeons were also surveyed on various aspects of this patient cohort to gain further insight and to complement findings from our study. RESULTS: Of the 37 patients included in the study, 34 underwent cosmetic procedures whilst 3 underwent bariatric procedures. 21 (57%) underwent procedures in Turkey, with abdominoplasty being the most common cosmetic procedure (n=17, 46%). The majority (n=34, 92%) had procedures classified as 'clean' surgeries. Significant positive microbiological cultures were identified in 22 (59%) patients, with Gram-negative organisms isolated in 15 of these cases (68%). In 17 cases (77%), the isolates were resistant to antimicrobials recommended by local empiric treatment guidelines. Length of hospital stay ranged from 1 to 107 days. CONCLUSIONS: SSIs following medical tourism may present challenges to local healthcare systems and involve a wide range of causative pathogens, meaning existing local empiric treatment guidelines are often inappropriate for this patient cohort. Public information campaigns, strengthening surveillance to enable accurate recording of emerging trends and complications, and updating empiric treatment guidelines for this patient cohort are all essential to optimise patient outcomes.
3. Clinical Analysis of Comprehensive Pharmacotherapy Combined With Ultrasound-Guided Precise Lesion Resection Plus Primary Microplasty in the Treatment of Nonpuerperal Mastitis.
In a retrospective comparison of 97 refractory NPM patients, ultrasound-guided precise lesion resection with primary microplasty plus comprehensive pharmacotherapy achieved similar complication rates, drainage time, and hospital stay versus extended resection, while showing a lower recurrence rate (0% vs 11.1%) over a median 16.8-month follow-up.
Impact: Suggests a strategy that preserves cosmesis without increasing complications and may reduce recurrence in refractory NPM, informing surgical decision-making and patient counseling.
Clinical Implications: For refractory NPM, integrating comprehensive pharmacotherapy with ultrasound-guided precise resection and primary microplasty may be preferred to extended resection to optimize cosmetic outcomes and reduce recurrence, pending confirmation in prospective trials.
Key Findings
- All 97 surgeries were completed without serious complications; follow-up exceeded 12 months (median 16.8 ± 2.9 months).
- No significant differences between groups in postoperative complications (7.7% vs 6.7%), drainage time (3.5 ± 0.3 vs 3.6 ± 0.4 days), or hospital stay (10.7 ± 0.6 vs 10.6 ± 0.5 days).
- Recurrence rate was lower in the observation group (0% [0/52]) versus control (11.1% [5/45]).
Methodological Strengths
- Sample size determined by a superiority test; retrospective stratification to balance baseline characteristics.
- Follow-up longer than 12 months, enabling short-to-midterm recurrence assessment.
Limitations
- Retrospective, single-center design without randomization may introduce selection bias.
- Detailed statistics for some outcomes (e.g., recurrence test metrics) are not fully reported in the abstract.
Future Directions: Conduct prospective, randomized trials to confirm recurrence and cosmetic benefits and to quantify patient-reported outcomes and cost-effectiveness.
OBJECTIVE: To explore the clinical efficacy, cosmetic outcome, and safety of comprehensive pharmacotherapy (traditional Chinese medicine + hormone + antibiotic) combined with ultrasound-guided precise lesion resection plus primary microplasty in the treatment of refractory nonpuerperal mastitis (NPM). METHODS: The clinical and pathological data of refractory NPM patients who underwent surgical treatment at our hospital from February 2021 to December 2024 were retrospectively analyzed. The sample size was calculated using a superiority test, and a total of 97 patients were finally included. They were assigned to two groups using a random number table for retrospective stratification assignment (to balance baseline clinical characteristics and reduce selection bias): The control group (45 cases) underwent extended lesion resection combined with fascial flap plasty and nipple-areola correction and the observation group (52 cases) underwent ultrasound-guided precise lesion resection plus primary microplasty. The recurrence rate, breast cosmetic score (Harris score), postoperative psychological status (24-item Hamilton Depression Rating Scale [HAMD-24]), hospital stay, and incidence of complications were compared between the two groups. RESULTS: All surgeries were successfully completed in both groups without serious complications. All patients were followed up for more than 12 months (median follow-up period: 16.8 ± 2.9 months). There were no statistically significant differences in the incidence of postoperative complications [7.7% (4/52) vs. 6.7% (3/45), p = 1], drainage time [(3.5 ± 0.3) d vs. (3.6 ± 0.4) d, t = -1.398, p = 0.166], and hospital stay [(10.7 ± 0.6) d vs. (10.6 ± 0.5) d, t = 0.894, p = 0.373] between the two groups. The recurrence rate of the observation group was lower than that of the control group [0% (0/52) vs. 11.1% (5/45), X CONCLUSION: For refractory NPM, the combination of comprehensive pharmacotherapy, ultrasound-guided precise lesion resection, and primary microplasty achieves remarkable therapeutic effects, characterized by reduced complication rates and low short-to-long-term recurrence. This integrated traditional Chinese and Western medicine strategy is not only safe and effective but also provides excellent cosmetic benefits for patients.
