Abstract
Autologous adipose tissue transplantation is widely used for cosmetic and reconstruction of various areas in the body, often to repair soft tissue volume loss or contoured deformation. However, the application of fat transplantation is limited by unstable and unpredictable volume retention rates. At present, promoting adipose tissue survival and inhibiting its death is the key to improve the effect of autologous fat transplantation. In this paper, we propose a hypothesis that ferroptosis exists in fat transplantation. The bases of this hypothesis include the following: (1) the association between ferroptosis and other programmed cell death; (2) the association between ferroptosis and ischemia-reperfusion injury; and (3) the use of ferroptosis inhibitors in the field of fat transplantation.

Abstract
AIM The aim of this study was to evaluate the effect of different metoprolol doses on fat graft survival. MATERIAL AND METHOD A total of 10 Sprague-Dawley rats were used in the study. The dorsal regions of the rats were separated into four quadrants: right and left cranial, and right and left caudal. Each quadrant was determined as a separate group. Fat grafts were harvested from the groin areas and incubated in 5 ml solutions containing 0.9% sodium chloride (control group), 1 mg/mL metoprolol (Group 1), 2 mg/mL metoprolol (Group 2), and 3 mg/mL metoprolol (Group 3), respectively. The fat grafts were then placed in pockets dissected in each of the 4 dorsal quadrants. After 3 months all the rats were euthanized. The fat grafts were removed together with the surrounding area to which they had passed. Histopathological examination was made with hematoxylin and eosin (HE) and Masson Trichrome staining, and immunohistochemical examination with fibroblast growth factor-2 and perilipin staining. RESULTS In the examinations made with HE and Masson Trichrome staining, the scores of Group 2 and Group 3 were determined to be significantly higher than those of the control group (p < 0.05). The Group 3 scores were significantly higher than those of Group 1 (p < 0.05). In the examinations made with fibroblast growth factor-2 staining, the scores of Group 2 and Group 3 were determined to be significantly higher than those of the control group (p < 0.05). The Group 3 scores were significantly higher than those of Group 1 and Group 2 (p < 0.05). In the examinations made with perilipin staining, the scores in Groups 1, 2, and 3 were higher than those of the control group (p < 0.05). CONCLUSION Although metoprolol has previously been shown to prolong the survival of fat grafts, the results of this study demonstrated immunohistochemically that as the metoprolol dose increased, so the quality and vitality of fat graft also increased.

Abstract
PURPOSE The purpose of this study was to evaluate short- and long-term outcome of injection augmentation with autologous adipose tissue (AAT) and calcium hydroxylapatite injection (CAHA) in patients with a unilateral vocal fold paralysis (UVFP). DESIGN/METHODS A retrospective cohort study was performed in patients diagnosed with UVFP, who had received injection augmentation with AAT or CAHA. Multidimensional voice analysis was performed before, 3 and 12 months after injection. This analysis included patient self-assessment (Voice Handicap Index-30), perceptual (overall dysphonia grade according to the GRBAS scale), aerodynamic (MPT, s/z ratio) and acoustic (fundamental frequency, dynamic range) parameters. Effects were assessed using a linear mixed model analysis. RESULTS Forty-six patients were available for evaluation, with a total of 53 injection augmentations (AAT n = 39; CAHA n = 14). We found significant improvement of patient self-assessment and perceptive voice outcome at 3 months, which were maintained at 12 months. In the CAHA group, s/z ratio and dynamic range of extreme frequencies also improved significantly over time. No statistically significant differences were found between the two treatments (AAT vs. CAHA). No major complications were reported. CONCLUSION This study, using a guide-line recommended panel of outcome parameters, shows a high success rate of injection augmentation with AAT or CAHA for patients with UVFP at 12 months with significant improvement in most voice outcome parameters, although voices do not completely normalize. There is no significant difference in outcome between the two materials.

Abstract
ABSTRACT The primary organ systems and tissues concerning plastic and reconstructive surgery include the integument, vasculature, subcutis, and peripheral nerves, because these may individually or collectively be injured requiring reconstruction, or indeed be used in reconstruction themselves through grafts, flaps, or anastomoses. Adrenergic receptors are present throughout these anatomic components on the vasculature, adipose, platelets, immune cells, keratinocytes, melanocytes, fibroblasts, peripheral nerves, and tendons. Herein, the influence of adrenergic signaling on the physiology of anatomic components related to plastic surgery is discussed, along with clinical considerations of this systems involvement in procedures, such as free flap reconstruction, skin grafting, fat grafting, and other areas relevant to plastic and reconstructive surgery. Current evidence as well as potential for further investigation is discussed.

Deferoxamine Protects Stromal/Stem Cells of "Lull pgm System"-Processed Lipoaspirates Against Damages Induced by Mitochondrial Respiration Inhibition. Aesthetic Plast Surg 2020; 44:168-176. [PMID: 31741067 DOI: 10.1007/s00266-019-01544-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Accepted: 11/03/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND The ischemic environment of the receiving area compromises the outcome of autologous fat grafts. The aim of this study was to isolate and expand the stromal vascular fraction from patient lipoaspirates and investigate the gain in cell viability exerted by some protective agents against the blockage of mitochondrial respiration. METHODS The aspirates were (1) washed, using the "Lull pgm system," (2) centrifuged and (3) decanted. The corresponding stromal vascular fractions were isolated, and after cell adherence selection, the stromal/stem cell subpopulations were exposed to Antimycin A for 1 h. Then, the protection induced by cell pretreatment with deferoxamine, diazoxide and IGF-1 was evaluated. RESULTS The residual cell viability of the "Lull pgm system"-washed samples was greater than that of the centrifuged samples (p < 0.05), and this advantage was maintained during the following 12 days of culture. The administration of 400 μM deferoxamine before Antimycin A treatment increased the number of viable cells from 56.5 to 80.8% (p < 0.05). On the contrary, the pretreatment with 250 μM diazoxide or 0.1 μg/ml IGF-1 did not exert any significant pro-survival action. Echinomycin abolished the positive effect of deferoxamine, suggesting that its protection involved HIF-1α. CONCLUSIONS Adipose-derived stromal-stem cells survive the inhibition of mitochondrial respiration better if the lipoaspirate is washed using the "Lull pgm system" rather than centrifuged. Moreover, a significant contribution to cell survival can be obtained by preconditioning stromal-stem cells with deferoxamine. In a clinical perspective, this drug could be safely administered before surgery to patients undergoing autologous fat transfer.

J Plast Reconstr Aesthet Surg 2019; 73:1166-1173. [PMID: 32269011 DOI: 10.1016/j.bjps.2019.11.010] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 11/07/2019] [Accepted: 11/22/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Cell-assisted lipotransfer (CAL) promotes the survival of fat grafts with high vascular density and improves skin quality by increasing collagen content. However, no study has quantified the changes on the skin surface, and rigorous methodological evaluations are still lacking. DESIGN Fifty patients were recruited and randomly divided into two groups: an experimental group (n = 25) that underwent a stromal vascular fraction (SVF)-assisted fat graft and a control group (n = 25) that underwent fat graft only. METHODS The SVF cells were counted, tested in terms of viability, and characterized. The volumes of whole faces were determined by using a 3D scanner and Geomagic software preoperation, immediately after surgery, and 6 months postoperation. Facial skin qualities, including spots, wrinkles, texture, pores, UV spots, brown spots, red areas, and porphyrins, were detected by a VISIA skin detector preoperation and 6 months postoperation. A visual analog scale was used for clinical evaluation. RESULTS The cell pellet contained 1-3 × 107/mL of fresh SVF cells. The cell viability exceeded 98%. The immunophenotyping characteristics and stemness were consistent with the features of adipose- derived stem cells (ADSCs). The survival rate of SVF-enriched fat grafts was significantly higher than that of control grafts: 77.6%±11.6% versus 56.2%±9.5% (p<0.001). The VISIA values of wrinkles (19.3 ± 6.6 versus 10.9 ± 5.5, p<0.001) and texture (15.8 ± 7.0 versus 10.3 ± 5.0, p<0.01) were significantly higher in SVF-enriched group than in control group at 6 months postoperation. During long-term follow-up, the majority of patients in both groups were satisfied with the final facial esthetic results. CONCLUSIONS Our results demonstrated the positive outcomes of autologous SVF-assisted fat graft in improving facial skin quality and its promising application potential in clinical settings. This study is registered at www. ClinicalTrials.gov, number NCT02923219.
