Background: Autologous fat transplantation (AFT) to the breast can correct defects and be a part of a breast reconstruction to achieve a better aesthetic result. The impact of AFT on the radiological evaluation and detection of cancer remains unclarified. The aim of this study is to investigate whether AFT induces lasting modifications.
Methods: In the present study, a valuation was performed of 44 breasts from 37 patients examined with mammography and ultrasound before and after autologous fat transplantation. Breast radiologists evaluated the images using a study specific protocol.
Results: AFT did not hinder post-operative assessment of mammograms or ultrasound. No detectable changes with serious clinical impact were found after injections of mean 177 ml (34-516) of fat in one to four sessions. The rate of oil cysts was significantly higher after AFT than pre-operatively (2.3 vs. 34.1 % p = 0.0013). Significantly more post-operative oil cysts were detected after injection of larger volumes of fat (144 vs. 243 ml, p = 0.013). No significant differences were found in the post-operative images regarding age at surgery, follow-up time, or time from previous breast surgery.
Conclusion: AFT does not impair assessment of mammograms and ultrasound in patients who have a history of breast cancer surgery or prophylactic mastectomy.

Metabolic syndrome (MetS) is associated with low-grade inflammation, which can be exacerbated by renal artery stenosis (RAS) and renovascular hypertension, potentially worsening outcomes through pro-inflammatory cytokines. This study investigated whether mesenchymal stem/stromal cells (MSCs) could reduce fat inflammation in pigs with MetS and RAS. Twenty-four pigs were divided into Lean (control), MetS, MetS + RAS, and MetS + RAS + MSCs.

A 54-year-old man underwent right S6 segmentectomy for right lung cancer. After discharge, he presented with fever, hemoptysis, and cough, and computed tomography showed an intermediate bronchus fistula. Because direct closure or bronchoplasty was challenging, a Dumon (Novatech) stent was inserted directly into the fistula from the surgical field and covered with an autologous pericardial patch, pedicled mediastinal fat, and intercostal muscle.

Background: Autologous fat grafting in the buttocks has gained great popularity However, one of the main risks is infiltration of fat into the systemic venous system, leading to potential complications such as macroscopic fatty embolism (MAFE), which can be fatal.
Objectives: This study evaluated the safety and efficacy of the LiRi (Linear Retrograde infiltration) for autologous fat grafting in the buttocks, and its evolution over a six-month follow-up period.
Methods: The procedure was performed in 114 patients.

Background: Superficial autologous fat grafting is widely used for facial rejuvenation and regenerative treatments, yet its retention rate remains unpredictable. Enhancing the concentration of adipose-derived stem cells (ASCs) has been shown to improve graft retention. Mechanical fat processing techniques can reduce fat granules size for superficial injection as well as elevate the concentration of ASCs.

Autologous fat grafting is a widely used technique in plastic and reconstructive surgery, but its efficacy is often limited by the poor survival rate of transplanted adipose tissue. This study aims to enhance the survival of fat grafts by investigating the role of thymosin beta-4 (Tβ4) in facilitating mitochondrial transfer from adipose-derived stem cells (ADSCs) to adipocytes and newly formed blood vessels within the grafts via tunneling nanotubes (TNTs). We demonstrate that Tβ4 upregulates the Rac/F-actin pathway, leading to an increased formation of TNTs and subsequent transfer of mitochondria from ADSCs.
