Mesenchymal stem cells-derived exosomes (MSCs-EXs) applications have brought a key breakthrough in treating type 1 diabetes mellitus (T1DM) and its diabetic complications. However, various recent strategies aimed to construct prominent engineered EXs with greater precision and higher efficiency for diabetes syndrome were conducted. In this research, we seek to enhance the medicinal potentialities of MSCs-EXs on type 1 diabetic rats' hepatic complications, via loading with either selenium (Se) or nano selenium (NSe) particles.

Article Synopsis
  • - Autologous postmastectomy breast reconstruction shows better long-term clinical outcomes and patient satisfaction compared to implant-based methods, but adjuvant radiotherapy has often been seen as a barrier to immediate reconstruction.
  • - Recent advancements in postmastectomy radiotherapy (PMRT) have reduced complications, yet plastic surgeons remain cautious about offering immediate flap-based reconstruction to patients requiring radiotherapy.
  • - At a recent workshop, experts concluded that PMRT should not be viewed as a deterrent to immediate autologous reconstruction, emphasizing goals like symmetry, softness, and skin preservation in the reconstruction process.

Background: Fibroepithelial lesions (FEL) are a heterogeneous group of biphasic tumours that include fibroadenomas (FA) and the rare entity of benign phyllodes tumors (PT) as well as cases where distinction between these two entities is not possible. The histologic distinction between benign PT and cellular FA is still a diagnostic challenge, especially in core-needle biopsy (CNB) or vacuum-assisted biopsy (VAB). Guidelines are not clearly established regarding the management of FEL in CNB or VAB.

Primarily, breast-conserving therapy is an oncological intervention, but eventually it is judged by its cosmetic result. Remaining cavities from tumor resection can promote seromas, delay healing and cause lasting discomfort. Additionally, volume loss, dislocation of nipple/areola and fat necrosis lead to (cosmetically) unfavorable results, aggravated by radiotherapy.

Most invasive lobular breast carcinomas (ILBCs) are luminal-type carcinomas with an HER2-negative phenotype (ERBB2 or HER2 un-amplified) and CDH1 mutations. Rare variants include ERBB2-amplified subtypes associated with an unfavorable prognosis and less response to anti-HER2 targeted therapies. We analyzed the clinicopathological and molecular features of ERBB2-amplified ILBC and compared these characteristics with ERBB2-unamplified ILBC.

While the DIEP (deep inferior epigastric perforator) flap has become the gold standard in autologous breast reconstruction due to its favourable tissue characteristics and preserved abdominal wall function, a constant attempt is done to improve the outcome of the donor site. Even if just a small detail, the umbilicus has a big impact on the overall aesthetic outcome of the donor site. As an already established technique in abdominoplasties, we introduced the neo-umbilicus as the standard procedure for DIEP donor site closure.

In autologous breast reconstruction, the internal mammary artery (IMA) and internal mammary vein (IMV) are the standard recipient vessels. Recently, the perforator vessels of the IMA and IMV were found to be a safe alternative as recipient vessels cause less morbidity and allow adequate flap. We describe 2 cases in which the IMA and IMV perforators were used as additional recipient vessels to overcome intraoperatively occurred complications.
