Article Abstract
Background: AlloDerm-RTU is a new member of human acellular dermal matrix (HADM) which was launched in 2012. The present meta-analysis aimed to investigate whether AlloDerm-RTU was superior compared with previous HADMs.
Methods: All available databases were searched for retrospective or prospective studies regarding breast reconstruction with AlloDerm-RTU compared with other HADMs. The primary outcome was the incidence of complications among different HADMs.
Results: Two prospective and seven retrospective studies with a total of 1406 patients were enrolled. There was no significant difference in any of the complications, including the incidence of hematoma (RR 0.78, 95%CI 0.19 to 3.19; P = 0.73), seroma (RR 0.98, 95%CI 0.43 to 2.26; P = 0.97), cellulitis (RR 0.82, 95%CI 0.32 to 2.11; P = 0.68), necrosis (RR 0.69, 95%CI 0.44 to 1.10; P = 0.12), infection (RR 0.68, 95%CI 0.37 to 1.25; P = 0.22), explantation (RR 0.61, 95%CI 0.35 to 1.06; P = 0.08), and total complications (RR 0.91, 95%CI 0.55 to 1.52; P = 0.73). Subgroup analysis showed that AlloDerm-RTU demonstrated no superiority compared with FD AlloDerm, AlloMax, or DermACELL. Sensitivity analysis indicated that the outcomes were stabilized. No publication bias existed in the present meta-analysis.
Conclusion: Four HADM products, AlloDerm-RTU, FD AlloDerm, AlloMax, and DermACELL, showed similar risks of complications. However since most of the included studies had a low level of evidence, further random trials with large numbers of patients are needed.

Background: Postmastectomy autologous reconstruction (PMAR) is an important component of comprehensive breast cancer care. Previous research has suggested the existence of sociodemographic disparities in complications after immediate PMAR. The objective of this study was to examine the impact of sociodemographic and clinical factors on immediate PMAR postoperative outcomes.

Tuberous breast deformity was first documented by Rees and Aston in 1976. The deformity is well documented in cisgender women, with rare cases in cisgender men often associated with gynecomastia, and almost no reports in transgender women. Herein, we present a case of a 32-year-old transgender woman who developed bilateral tuberous breast deformity after 10 years of hormone replacement therapy.

We present the case of a 45-year-old Caucasian woman diagnosed with synchronous bicentric breast cancer of differing molecular phenotypes in the same breast. The first tumor, an invasive ductal carcinoma (G1), was estrogen and progesterone receptor-positive and HER2-negative, with a low proliferative index (Ki67 10%). A second lesion, located in a different quadrant and appearing within weeks after biopsy, exhibited a triple-negative phenotype and a higher proliferative index (Ki67 30%).

Stakeholders in the breast implant industry in Korea have recently experienced a crisis from breast implant-associated anaplastic large cell lymphoma and the first Korean case of a medical device fraud. We compared the short-term safety between the microtextured devices that are commercially available after the occurrence of breast implant crisis in Korea. The current study was conducted in a cohort of Korean women who had received an implant-based augmentation mammaplasty for aesthetic purposes between November 14, 2020 and October 13, 2022.

Breast cancer (BC), characterized by its heterogeneity and diverse subtypes, necessitates personalized treatment strategies. This study presents MF3Ec-TBPP nanoparticles (NPs) as a promising approach, integrating an aggregation-induced emission (AIE)-based photosensitizer, TBPP, with the MF3Ec aptamer to enhance targeted photodynamic therapy (PDT) for Luminal A subtype BC cells. The nanoparticles also feature a 1, 2-distearoyl-sn-glycero-3-phosphoethanolamine-poly(ethylene glycol) shell and dipalmitoyl phosphatidylcholine (DPPC), which stabilize the structure and inhibit singlet oxygen generation, effectively reducing off-target effects and protecting healthy tissues.
