1. Predicting orthognathic surgery results as postoperative lateral cephalograms using graph neural networks and diffusion models.
The authors introduce GPOSC-Net, combining a landmark prediction module with a latent diffusion model to synthesize realistic post-operative lateral cephalograms from pre-operative inputs. Multi-dataset validation, a visual Turing test, and simulation studies show accurate landmark prediction and high-fidelity image generation, supporting use in planning and patient communication.
Impact: Provides a novel, generalizable AI workflow for predicting and visualizing post-surgical outcomes, potentially changing orthognathic surgical planning and patient counseling.
Clinical Implications: May improve shared decision-making, expectation management, and procedural planning by previewing plausible post-op morphology; could reduce revisions by aligning plans with predicted outcomes.
Key Findings

Orthognathic surgery, or corrective jaw surgery, is performed to correct severe dentofacial deformities and is increasingly sought for cosmetic purposes. Accurate prediction of surgical outcomes is essential for selecting the optimal treatment plan and ensuring patient satisfaction. Here, we present GPOSC-Net, a generative prediction model for orthognathic surgery that synthesizes post-operative lateral cephalograms from pre-operative data. GPOSC-Net consists of two key components: a landmark prediction model that estima
2. N6-methyladenosine methyltransferase Wilms tumor 1-associated protein impedes diabetic wound healing through epigenetically activating DNA methyltransferase 1.
WTAP is upregulated in high-glucose endothelial cells and impairs angiogenic and migratory functions central to wound repair. WTAP knockdown improves in vitro endothelial function and in vivo wound closure while reducing m6A modification and expression of DNMT1; DNMT1 overexpression rescues the phenotype, identifying a WTAP–DNMT1 axis that hinders diabetic wound healing.
Impact: Reveals an actionable epigenetic mechanism linking m6A modification to impaired diabetic wound repair, pointing to WTAP/DNMT1 as therapeutic targets.
Clinical Implications: Suggests pharmacologic inhibition of WTAP or DNMT1—or modulation of m6A signaling—as potential strategies to enhance wound healing in diabetes, relevant to reconstructive and dermatologic care.
Key Findings
- WTAP shows the greatest upregulation among m6A methyltransferases in high-glucose HUVECs.
- WTAP knockdown restores endothelial viability, tube formation, and migration suppressed by high glucose.
- In vivo WTAP knockdown accelerates wound closure with enhanced re-epithelialization and collagen deposition.
- WTAP increases m6A modification and expression of DNMT1; DNMT1 overexpression reverses benefits of WTAP knockdown.
Methodological Strengths
- Mechanistic linkage established with both in vitro endothelial assays and in vivo wound models.
- Rescue experiments (DNMT1 overexpression) strengthen causality for the WTAP–DNMT1 axis.
Limitations
- High-glucose HUVECs and murine wounds may not fully reflect human diabetic wound biology.
- Therapeutic modulation was not assessed in clinically relevant delivery systems or human trials.
Future Directions: Test small-molecule or RNA-based WTAP/DNMT1 modulators in diabetic large-animal models; profile off-target effects and interactions with standard wound care.
BACKGROUND: Diabetic wound injury is a significant and common complication in individuals with diabetes. N6-methyladenosine (m6A)-related epigenetic regulation is widely involved in the pathogenesis of diabetes complications. However, the function of m6A methyltransferase Wilms tumor 1-associated protein (WTAP) in diabetic wound healing remains elusive. AIM: To investigate the potential epigenetic regulatory mechanism of WTAP during diabetic wound healing. METHODS: Human umbilical vein endothelial cells (HUVECs) were induced with high glucose (HG) to establish RESULTS: The expression of several m6A methyltransferases, including METTL3, METTL14, METTL16, KIAA1429, WTAP, and RBM15, were measured. WTAP exhibited the most significant elevation in HG-induced HUVECs compared with the normal control. WTAP depletion notably restored cell viability and enhanced tube formation ability and migration of HUVECs suppressed by HG. The unclosed wound area of mice was smaller in WTAP knockdown-treated mice than in control mice at nine days post-wounding, along with enhanced re-epithelialization rate and collagen deposition. The m6A levels on DNMT1 mRNA in HUVECs were repressed by WTAP knockdown in HUVECs. The mRNA levels and expression of DNMT1 were inhibited by WTAP depletion in HUVECs. Overexpression of DNMT1 in HUVECs notably reversed the effects of WTAP depletion on HG-induced HUVECs. CONCLUSION: WTAP expression is elevated in HG-induced HUVECs and epigenetically regulates the m6A modification of DNMT1 to impair diabetic wound healing.
3. Wise Versus Vertical Mastopexy Pattern Skin-reducing Mastectomy With Immediate Breast Reconstruction: Systematic Review and Meta-analysis.
Across 39 studies (1,954 patients; 2,311 reconstructions), Wise-pattern skin-reducing/sparing mastectomy was associated with a significantly higher total flap necrosis rate than the vertical pattern, while major/minor necrosis, infection, hematoma, and seroma did not differ. The analysis used both Bayesian and frequentist GLMMs accommodating zero-event studies.
Impact: Provides synthesis-level evidence to guide incision pattern selection in immediate reconstruction, with direct implications for flap viability and cosmetic outcomes.
Clinical Implications: Consider vertical mastopexy patterns where feasible to reduce flap necrosis risk; counsel patients accordingly and weigh trade-offs with exposure/access and oncologic safety.
Key Findings
- Meta-analysis of 39 studies (1,954 patients; 2,311 breasts) comparing Wise vs vertical mastopexy patterns.
- Wise pattern associated with higher total mastectomy flap necrosis (14.2%; 95% CI 10%–20%) and significantly higher than vertical pattern.
- No significant differences in major/minor necrosis, infection, hematoma, or seroma between patterns.
Methodological Strengths
- PRISMA-guided search and selection across multiple databases.
- Use of both Bayesian and frequentist GLMMs including zero-event studies.
Limitations
- Predominantly observational studies with potential confounding and heterogeneity.
- Operative technique variations and patient selection criteria may bias pooled estimates.
Future Directions: Prospective, standardized, ideally randomized trials comparing incision patterns with core outcome sets and stratification by patient risk.
BACKGROUND: This study compares postoperative outcomes of Wise and vertical mastopexy pattern skin-reducing/skin-sparing masctomy, hypothesizing that incision choice affects cosmetic outcomes and complication rates. METHODS: A systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searching PubMed, MEDLINE, Embase, Web of Science, and StarPlus Library. Included studies documented skin-sparing mastectomy using Wise or vertical mastopexy patterns with immediate reconstruction. The primary outcome is total mastectomy flap necrosis. The secondary outcomes are major/minor necrosis, infection, hematoma, seroma, and wound complications. Bayesian and frequentist generalized linear mixed models were used for the meta-analysis, including studies with 0 events. RESULTS: Sixty-six studies were identified, with 39 included in the meta-analysis, comprising 1954 patients and 2311 breast reconstruction cases. The Wise group had a higher rate of mastectomy flap necrosis (14.2%; 95% confidence interval: 10%-20%; CONCLUSIONS: The Wise pattern shows significantly higher mastectomy flap necrosis than the vertical pattern. However, there were no significant differences in major necrosis, minor necrosis, infection, hematoma, or seroma. Future studies should focus on larger, high-quality randomized controlled trials to better understand the impact of incision techniques on postoperative outcomes.
