Autologous Fat Transplantation

Abstract Background Autologous fat is currently one of the most commonly used soft tissue materials in plastic surgery, but the changes that occur in fat after transplantation are unclear. Existing studies on the changes in surviving fat mostly involve animal experiments. Objectives The aim of this study was to obtain surviving fat 1 year after clinical autologous fat transplantation for breast augmentation, to explain the microenvironmental changes after fat transplantation from a clinical perspective, and to verify previous research conclusions, thus providing new insight into fat survival. Methods Samples of surviving fat were obtained from 5 patients 1 year after they had undergone autologous fat transplantation for breast augmentation, and normal fat samples were obtained from 5 patients who had not undergone this procedure. The differences between CD68 and CD31 were analyzed immunohistochemically, and between CD34 and Ki67 by immunofluorescence. We also tested whether UCP-1 is expressed in surviving fat. Results The relative CD68, CD34, and Ki67 expression levels in the surviving fat tissue were significantly higher than those in the normal fat tissue (PCD68 = 0.04, PCD34 = 0.03, PKi67 = 0.02). The relative CD31 expression was not significantly different between the two groups (P = 0.52). No UCP-1 expression was observed in any surviving fat tissue. Conclusions Chronic inflammatory reactions mediated by macrophages were detectable 1 year after autologous fat transplantation for breast augmentation. The mesenchymal stem cell content in surviving fat was higher than that in normal fat, but the number of blood vessels was close to that in normal breast fat tissue. No genesis of brown fat was found. Level of Evidence: 5

The objective of the study is to show significance of desynchronosis laboratory markers in risk assessment of metabolic syndrome (MS) development. Materials and Methods. There were examined 98 men, aged 43-88, diagnosed with dyscirculatory encephalopathy showing one and more risk factors for development of cardiovascular diseases. They were divided into 2 groups according to the international guidelines of 2009: with MS (n = 61) and without MS (n = 37). Parameters of fats, glucose metabolism, inflammatory mediators, fat tissue metabolism markers, melatonin metabolite excretion (6-sulfatoxymelatonin) were defined in blood serum and urine. Results. The article presents data on changes in leptin, adiponectin, PAI-1, testosterone production and 6-sulfatoxymela-tonin excretion in patients with MS. There are calculated threshold values of these markers definitely increasing MS risk and logistic regression equation which allows assessing MS risk for an individual patient. Conclusion. Detected disorders of melatonin synthesis diurnal dynamics in patients with MS and interconnection between melatonin production and adiponectin, leptin, PAI-1, testosterone synthesis allow considering these parameters as desynchronosis markers significant for MS development.

The rate of detection of breast cancer by MRI, while other methods of radiological diagnosis are not sufficiently informative, ranges from 5.2 to 26.3 per cent. Suspicious breast tumors of category BI-RADS 4, 5 show morphological image-guided biopsy verification, in particular MRI with contrast. Purpose. To show the possibilities and features of carrying out MRI-guided vacuum breast biopsy, including after aesthetic breast augmentation. Material and methods. A comprehensive X-ray, ultrasound and MRI examination of 54 women aged between 28 and 70 years with different breast tumors was conducted. Of these, five were detected only by breast MRI with contrast, and were morphologically verified by MRI-guided vacuum aspiration biopsy. Results. 14 of the 54 patients with breast mass were diagnosed with breast cancer and 26 were diagnosed with benign diseases. The effectiveness of comprehensive examination and low-invasive high-tech MRI-guided procedures in early refined screening for breast cancer, including after aesthetic breast augmentation, has been demonstrated. MRI-guided vacuum-assisted breast biopsy is a fast, safe and accurate diagnostic method of morphological verification of suspicious breast tumors that do not have X-ray and ultrasound.
