1. Effect of vacuum bell therapy on subcutaneous fat of the chest wall in patients with pectus excavatum.
In 47 children with pectus excavatum, one year of vacuum bell therapy reduced Haller index and markedly increased anterior chest wall subcutaneous fat thickness in 96% of patients. Cosmetic surface improvement exceeded skeletal remodeling, indicating a dual mechanism of benefit.
Impact: This prospective imaging study reframes how noninvasive chest wall therapy achieves cosmetic improvement by quantifying device-associated adipogenesis. It directly informs patient counseling and outcome interpretation.
Clinical Implications: When counseling families about vacuum bell therapy, set expectations that visible improvement derives from both skeletal remodeling and increased anterior chest wall adipose tissue. Monitoring should emphasize surface changes without overattributing improvements solely to skeletal correction.
Key Findings
- Haller index improved from 3.6 ± 0.7 to 3.2 ± 0.5 after one year of therapy.
- Anterior chest wall subcutaneous fat thickness increased in 45/47 patients (95.7%), from 4.0 ± 2.1 mm to 7.6 ± 3.3 mm.
- Surface depression improvement (4.0 ± 3.3 mm) exceeded skeletal depression improvement (1.4 ± 3.8 mm), supporting a dual cosmetic mechanism.
- No significant predictors of fat thickness change were identified in multivariable analysis; mean FIR was 95%.
Methodological Strengths
- Prospective, paired low-dose CT assessments at baseline and one year
- Objective, multi-parameter quantification (HI, correction index, fat thickness, SkD/SuD)
Limitations
- Single-center, pediatric cohort without a control group
- Short to mid-term horizon (1 year) and radiation-based measurements
Future Directions: Longitudinal studies to assess persistence or reversibility of adipose thickening; multimodal imaging (e.g., MRI/ultrasound) to reduce radiation; mechanistic studies of vacuum-induced adipogenesis and age/dose-response effects.
BACKGROUND: Vacuum bell therapy is increasingly used as a nonoperative treatment for pectus excavatum (PE). However, whether this intervention induces subcutaneous fat thickening and the mechanisms underlying such changes remain uncertain. This study aimed to quantify vacuum bell-associated adipose tissue changes and clarify their clinical implications. METHODS: Patients with PE treated with vacuum bell therapy at our center between July 2022 and January 2024 underwent low-dose chest computed tomography at treatment initiation and after one year of therapy. Measured parameters included the Haller index (HI), correction index, anterior and lateral chest wall subcutaneous fat thickness, skeletal depression depth (SkD), and surface depression depth (SuD). The fat influence rate (FIR) was calculated to quantify device-related adipogenesis stimulation. Multiple regression analysis was performed to identify factors associated with changes in anterior chest wall fat thickness. RESULTS: Forty-seven patients were included, with a median age of 7.0 years (range: 1-14). The mean HI decreased from 3.6 ± 0.7 to 3.2 ± 0.5, with improvement observed in 35 patients (74.5%). Anterior chest wall fat thickness increased in 45 patients (95.7%), rising from 4.0 ± 2.1 mm to 7.6 ± 3.3 mm. The mean FIR was 95% (IQR: 39%). Improvement in surface depression (4.0 ± 3.3 mm) exceeded skeletal improvement (1.4 ± 3.8 mm), and no predictors reached statistical significance in regression analysis. CONCLUSIONS: Vacuum bell therapy is effective and induces substantial anterior chest wall fat thickening, indicating that cosmetic improvement results from a dual mechanism involving skeletal remodeling and adipose thickening. LEVEL OF EVIDENCE: Level III.
2. Proteomic and experimental analyses reveal molecular signatures of flexural atopic dermatitis in antecubital and popliteal fossae and the therapeutic effect of Aida lotion.
Proteomic profiling of flexural versus extensor skin in five patients revealed 712 differential proteins, with PPAR and MAPK pathways (e.g., CYP27A1, CPT1A, FABP5, MAP2K3, MAP2K1, HRAS) implicated in antecubital/popliteal atopic dermatitis. In a mouse model, Aida lotion reversed pathway activation and alleviated inflammation, suggesting targetable, site-specific mechanisms.
Impact: By integrating human proteomics with in vivo validation, this study uncovers site-specific molecular drivers of flexural dermatitis and a plausible topical mechanism, offering translational targets for precision dermatology.
Clinical Implications: Although preliminary, the identified PPAR/MAPK-linked proteins could serve as biomarkers for flexural atopic dermatitis and inform development of targeted topicals; clinical trials are needed before practice changes.
Key Findings
- Identified 712 differentially expressed proteins between flexural and extensor sites in atopic dermatitis.
- PPAR (e.g., CYP27A1↓, CPT1A↑, FABP5↑) and MAPK (e.g., MAP2K3↑, MAP2K1↑, HRAS↑) pathways were enriched in flexural lesions.
- In a mouse model, Aida lotion downregulated CPT1A, FABP5, MAP2K3, MAP2K1, HRAS and upregulated CYP27A1, improving dermatitis and reducing inflammatory/mast cell infiltration.
Methodological Strengths
- Ultra-sensitive proteomics with bioinformatic pathway enrichment
- Cross-validation in an atopic dermatitis mouse model demonstrating mechanistic congruence
Limitations
- Very small human sample (n=5) and non-random sampling
- Therapeutic effects assessed only in animals; no clinical trial of the lotion
Future Directions: Validate signatures in larger, multi-center cohorts; incorporate spatial omics to resolve site-specific microenvironments; conduct dose-ranging randomized trials of targeted topicals guided by these biomarkers.
INTRODUCTION: The mechanisms underlying the predilection of atopic dermatitis for the antecubital and popliteal fossae remain unexplored. This preliminary exploratory study aimed to characterize the proteomic features of typical flexural atopic dermatitis lesions using proteomics integrated with animal model validation and to clarify the therapeutic mechanisms of Aida lotion. METHODS: We recruited five patients with atopic dermatitis. Skin scale samples were collected from the flexural side of the antecubital and popliteal areas as the observation group, while samples from the corresponding extensor sides were used as the control group. Stratum corneum specimens were analyzed using ultra-sensitive proteomic techniques and bioinformatics to screen for differentially expressed proteins. Key candidate proteins were then validated in an atopic dermatitis mouse model to further explore the therapeutic mechanisms of Aida lotion. RESULTS: A total of 712 differential proteins were identified. GO analysis indicated enrichment in pathways related to DNA replication, proteasome regulation, and myosin V binding. KEGG pathway analysis highlighted the importance of the PPAR and MAPK signaling pathways in the site-specific prevalence of atopic dermatitis. Key differentially expressed proteins including CYP27A1, CPT1A, FABP5 in the PPAR pathway and MAP2K3, MAP2K1, HRAS in the MAPK pathway, showed the highest fold changes. Animal experiments showed that atopic dermatitis induction increased SCORAD scores, edema, and inflammatory infiltration. Additionally, the expression levels of CPT1A, FABP5, MAP2K3, MAP2K1, and HRAS were upregulated, whereas the expression of CYP27A1 was downregulated, which was consistent with the proteomic findings, indicating that these targets have been validated as key proteins associated with the molecular pathology of flexural atopic dermatitis lesions in antecubital and popliteal fossa regions. Treatment with Aida lotion reversed these changes by downregulating CPT1A, FABP5, MAP2K3, MAP2K1, and HRAS, and upregulating CYP27A1, thereby alleviating dermatitis symptoms and reducing inflammatory and mast cell infiltration. DISCUSSION: These findings identify CYP27A1, CPT1A, FABP5, MAP2K3, MAP2K1, and HRAS are prominent molecular signatures of atopic dermatitis in the antecubital and popliteal fossae. Aida lotion exerts therapeutic effects by modulating these key proteins and associated pathways.
3. A meta-analysis of complications of thread lifting.
Across 26 studies (n=2,827), pooled complication incidences after thread lifting were 34% swelling, 26% ecchymoses, 10% visible/palpable threads, and 7% dimpling, with high between-study heterogeneity. Findings emphasize the importance of technique mastery, patient selection, and expectation management.
Impact: This PRISMA-guided quantitative synthesis delivers the most comprehensive complication rates for thread lifting to date, directly informing consent processes and procedural training.
Clinical Implications: Use pooled incidence data during consent to set realistic expectations and prepare protocols for common adverse events (e.g., swelling, bruising). Emphasize technique refinement to minimize thread visibility/palpability and dimpling.
Key Findings
- Included 26 studies totaling 2,827 patients under PRISMA guidance.
- Pooled complication rates: swelling 34%, ecchymoses 26%, visible/palpable threads 10%, skin dimpling 7%.
- High heterogeneity across studies limits precision but underscores variability in techniques, materials, and follow-up.
Methodological Strengths
- Systematic PRISMA-based approach with quantitative pooling
- Large aggregate sample size improving external generalizability
Limitations
- High heterogeneity and inclusion of lower-quality observational designs
- Variable and often short follow-up; potential publication bias
Future Directions: Standardize complication definitions and follow-up windows; develop prospective registries and comparative studies by suture type and technique; evaluate mitigation strategies in pragmatic trials.
OBJECTIVE: This study aims to systematically review and perform a meta-analysis on the complications associated with thread lifting, a popular minimally invasive aesthetic procedure, to determine the incidence and types of adverse effects. METHODS: A comprehensive literature search was conducted across major medical databases including PubMed, Embase, and Web of Science, covering all publications up to April 1, 2024. The search terms included "thread lift," "suture lift," "barbed suture," "facelift," and "nonsurgical facelift," combined with "complications" or "adverse effects." Only prospective or retrospective cohort studies, clinical randomized controlled trials (RCTs), and case series published in English were included. Studies were excluded if they were non-English, review articles, case reports, or conference abstracts with incomplete data. Study selection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data on authors, publication year, study design, sample size, patient demographics, follow-up duration, and complications were extracted and analyzed using RevMan 5.4. Heterogeneity among studies was assessed using the I RESULTS: Our comprehensive search initially identified 537 articles. After rigorous title and abstract screening, 213 articles were further assessed, with 26 studies ultimately included in the final analysis, representing a collective sample of 2,827 patients. The meta-analysis highlighted varying incidence rates of complications associated with thread lifts: swelling was reported in 34% of cases, visible or palpable threads in 10%, skin dimpling in 7%, and ecchymoses in 26%. The analysis also revealed high heterogeneity among the studies, with I CONCLUSION: Thread lifting, while generally safe, does carry a risk of several complications, which vary widely in their occurrence. This meta-analysis provides a detailed overview of the risk profile of thread lifting procedures, highlighting the need for careful patient selection and technique mastery by practitioners. The findings underscore the importance of setting realistic patient expectations and preparing for potential adverse effects.
