Abstract
INTRODUCTION Mycobacterium abscessus infection after liposuction/fat grafting is a rare complication that is hard to diagnose and treat. Misdiagnosis could result in treatment failure and prolonged hospital stays. The paradoxical reaction is another complication that rarely occurs in non-HIV patients infected with nontuberculosis mycobacteria. This study reported 3 cases infected with M. abscessus complicated by the paradoxical reaction after liposuction and fat grafting. It highlighted characteristics giving clues of the paradoxical reaction and a successful strategy. Also, a systematic review was conducted to comprehensively provide varied aspects of M. abscessus infection after liposuction and/or fat grafting. METHODS Three cases were retrospectively included reporting data characteristics of patients, cosmetic procedures, and treatment strategy. PubMed, Scopus, Virtual Health Library (VHL), and Global Health Library (GHL) were searched to find and include cases with M. abscessus infection after liposuction and/or fat grafting based on defined selection criteria. Relevant data were extracted and summarized. The risk of bias in included studies was assessed using JBI critical appraisal checklists. RESULTS Twenty-four articles were included in the systematic review. Symptoms often developed approximately 1 month after the cosmetic surgery. Culture, AFB, and PCR were common methods of diagnosis of M. abscessus after liposuction and/or fat grafting. It took about 33 days on average from the presentation to isolate and detect the pathogens. Antibiotics based on susceptibility testing results along with surgical interventions were effective methods of treatment. Our three cases which were complicated by the paradox were addressed by adding methylprednisolone for 2 weeks to the macrolide-based therapy. CONCLUSIONS Awareness of this disease should be widely raised among physicians for early diagnosis and proper treatments. Cultures of specimens and AFB should be repeated many times before excluding the possibility of Mycobacterium spp. A paradoxical reaction should be suspected if the symptoms were worse after the antibiotic therapy based on susceptibility testing results and proper surgical interventions, especially if patients had taken corticosteroids before being admitted.

Abstract
BACKGROUND Liposuction is one of the most common procedures used for body contouring. In this study, we aimed to determine whether there is a weight change with VASER-assisted liposuction (VAL) procedure and the demographic factors affecting it. METHODS A total of 51 patients (30 females and 21 males) who underwent VAL between the years of 2020 and 2022 were included in the study. Participants' weights before VAL, body mass indexes (BMI), aspiration volumes, demographic data, and weights and BMIs one month after VAL were recorded and analyzed. In addition, the fat ratio in the aspirate was determined in ten patients. RESULTS The mean aspiration volume with VAL was 4832.50 ± 2373.26 ml in females and 5176.90 ± 1602.61 ml in males. Body weights (baseline, 90.34 ± 9.17 vs. 71.01 ± 8.87; one month later, 86.95 ± 8.34 vs. 66.28 ± 10.04: p < 0.001) and BMIs (baseline, 28.59 ± 2.97 vs. 26.40 ± 3.69; one month later, 27.54 ± 2.92 vs. 24.59 ± 3.76: p = 0.009) were higher in males than females, both at baseline and after VAL. There was a significant decrease in body weights and BMIs after VAL in both females (4.73 ± 4.73 kg) and males (3.39 ± 4.27 kg) (p < 0.001). However, no correlation was observed between the decrease in body weights and BMIs after VAL and gender, age, aspirate volume, and fat volume. CONCLUSION Although there was a decrease in mean body weight and mean BMI in both males and females one month after VAL, no associations were observed between weight drop after VAL and gender, age, aspiration volume, and fat volume.

Abstract
BACKGROUND Abdominal obesity has been associated with an increased risk of insulin resistance, metabolic syndrome, and diabetes. Central fat removal procedures such as liposuction, lipectomy, and abdominoplasty are among the most common surgical procedures. The impact of the latter on the former is controversial and understudied. The authors aimed to explore the effect of subcutaneous fat elimination procedures on insulin resistance measures and adipokine levels. METHODS Relevant studies regarding the effects of surgical subcutaneous fat removal on glucose, insulin, adipokines, and lipid metabolism, as well as blood pressure, were identified by searching PubMed and Ovid-Cochrane without limits in date, type of publication, or language. After the selection process, 24 studies were obtained. The results of the articles were summarized using descriptive statistics. For the final analysis, a randomized effects model was used to evaluate heterogeneity; averages and meta-analytic differences were expressed with a confidence interval of 95%. RESULTS All studies reported a reduction in weight (-2.64 kg; 95% CI, -4.32 to -0.96; P = 0.002; I 2 = 36%; P of I 2 < 0.001) and body mass index after liposuction. A significant improvement in triglycerides (-10.06 mg/dL; 95% CI, -14.03 to -6.09; P < 0.001; I 2 = 48%; P of I 2 = 0.05), serum glucose concentration (-4.25 mg/dL; 95% CI, -5.93 to -2.56; P < 0.001; I 2 = 68%; P of I 2 < 0.001), serum insulin concentration (-2.86 μIU/mL; 95% CI, -3.75 to -1.97; P < 0.001; I 2 = 59%; P of I 2 = 0.003), and serum leptin concentration (-7.70 ng/mL; 95% CI, -11.49 to -3.92; P = 0.0001; I 2 = 96%; P of I 2 < 0.001) was consistently observed. CONCLUSION In addition to weight loss, there is a significant decrease in leptin, triglyceride, glucose, and insulin serum concentrations after liposuction, a fact that should be considered in future discussions.

Abstract
BACKGROUND Bariatric surgery averts obesity-induced insulin resistance and the metabolic syndrome. By contrast, surgical fat removal is considered merely an esthetic endeavor. The aim of this article was to establish whether surgical fat removal, similar to bariatric surgery, exerts measurable, lasting metabolic benefits. METHODS PubMed, Embase, and Scopus were searched using the Polyglot Search Translator to find studies examining quantitative expression of metabolic markers. Quality assessment was done using the MethodologicAl STandard for Epidemiological Research scale. The robust-error meta-regression model was employed for this synthesis. RESULTS Twenty-two studies with 493 participants were included. Insulin sensitivity improved gradually with a maximum reduction in fasting insulin and homeostatic model assessment for insulin resistance of 17 pmol/L and 1 point, respectively, at postoperative day 180. Peak metabolic benefits manifest as a reduction of 2 units in body mass index, 3 kg of fat mass, 5 cm of waist circumference, 15 µg/L of serum leptin, 0.75 pg/ml of tumor necrosis factor-alpha, 0.25 mmol/L of total cholesterol, and 3.5 mmHg of systolic and diastolic blood pressure that were observed at day 50 but were followed by a return to preoperative levels by day 180. Serum high-density lipoproteins peaked at 50 days post-surgery before falling below the baseline. No significant changes were observed in lean body mass, serum adiponectin, resistin, interleukin-6, C-reactive protein, triglyceride, low-density lipoproteins, free fatty acids, and fasting blood glucose. CONCLUSION Surgical fat removal exerts several metabolic benefits in the short term, but only improvements in insulin sensitivity last beyond 6 months.

Abstract
BACKGROUND Current literature clearly outlines the complication rates of liposuction in general; however, data specific to large-volume liposuction (LVL) remain unclear. OBJECTIVES The authors aimed to synthesize the current evidence on the safety of LVL with this systematic review. METHODS A comprehensive search in the MEDLINE, EMBASE, and CENTRAL databases was conducted for primary clinical studies reporting on safety or complications related to aesthetic LVL from 1946 to March 2020. The primary outcome measure was the incidence of surgical complication, and the secondary outcome measure was changes in metabolic profile. Meta-analyses were conducted to pool the estimated surgical complication incidence and metabolic changes. RESULTS Twenty-three articles involving 3583 patients were included. The average aspirate volume was 7734.90 mL (95% CI = 5727.34 to 9742.45 mL). The pooled overall incidence of major surgical complications was 3.35% (95% CI = 1.07% to 6.84%). The most common major complication was blood loss requiring transfusion (2.89% [95% CI = 0.84% to 6.12%]) followed by pulmonary embolism (0.18% [95% CI = 0.06% to 0.33%]), hematoma (0.16% [95% CI = 0.05% to 0.32%]), necrotizing fasciitis (0.13% [95% CI = 0.04% to 0.29%]), and deep vein thrombosis (0.12% [95% CI = 0.03% to 0.27%]). No fat embolism or death was reported in the included studies. The pooled overall incidence of minor surgical complication was 11.62% (95% CI = 6.36% to 18.21%), with seroma being the most common minor complication (5.51% [95% CI = 2.69% to 9.27%]). Reductions in lipid profile, glucose profile, body weight, and hematocrit level were observed after LVL. CONCLUSIONS The authors meta-analyzed and highlighted the complication rates specifically related to LVL in this study; however, the current data are limited by the lack of level 1 evidence.

Abstract
Liposuction is becoming an increasingly common procedure of aesthetic surgery, that patients choose to shape the body. Apart from the risks associated with the surgery, one should also consider whether the reduction of adipose tissue can significantly affect the metabolism of lipids and carbohydrates and, indirectly, that of bone tissue. The aim of the presented study was to assess the effects of small-volume liposuction surgery in the gluteal-femoral region on the selected markers of carbohydrate, lipid, and bone metabolism. The study included 27 women (40.75 ± 13.67 years of age, BMI = 25.9 ± 4.13 kg/m2) subjected to the removal of 3.35 ± 0.994 L of adipose tissue to shape the body. Following the procedure, significant changes in the body composition and body adiposity indicators were observed in these women. A slight decrease in adiponectin, leptin, resistin and insulin levels and HOMA-IR value was found three months after the procedure. No changes in the lipid profile of the subjects were found. It can be concluded that the removal of a small volume of adipose tissue from the gluteal-femoral region has a slight but positive effect on carbohydrate and lipid metabolism, providing a decreased risk of developing insulin resistance.

Abstract
The protective effects of lower body subcutaneous adiposity are linked to the depot functioning as a "metabolic sink" receiving and sequestering excess lipid. This postulate, however, is based on indirect evidence. Mechanisms that mediate this protection are unknown. Here we directly examined this with progressive subcutaneous adipose tissue removal. Ad libitum chow fed mice underwent sham surgery, unilateral or bilateral removal of inguinal adipose tissue or bilateral removal of both inguinal and dorsal adipose tissue. Subsequently mice were separated into 5 week chow or 5 or 13 week HFD groups (N = 10 per group). Primary outcome measures included adipocyte distribution, muscle and liver triglycerides, glucose tolerance, circulating adipocytokines and muscle insulin sensitivity. Subcutaneous adipose tissue removal caused lipid accumulation in femoral muscle proximal to excision, however, lipid accumulation was not proportionally inverse to adipose tissue quantity excised. Accumulative adipose removal was associated with an incremental reduction in systemic glucose tolerance in 13 week HFD mice. Although insulin-stimulated pAkt/Akt did not progressively decrease among surgery groups following 13 weeks of HFD, there was a suppressed pAkt/Akt response in the non-insulin stimulated (saline-injected) 13 week HFD mice. Hence, increases in lower body subcutaneous adipose removal resulted in incremental decreases in the effectiveness of basal insulin sensitivity of femoral muscle. The current data supports that the subcutaneous depot protects systemic glucose homeostasis while also protecting proximal muscle from metabolic dysregulation and lipid accumulation. Removal of the "metabolic sink" likely leads to glucose intolerance because of decreased storage space for glucose and/or lipids.

Abstract
BACKGROUND Suction-assisted lipectomy is one of the most frequent procedures in plastic surgery. The aim of this study was to investigate whether suction-assisted lipectomy causes changes in the carbohydrates and lipid metabolism and the potential effects on cardiovascular risk factors. METHODS We interrogated five databases: Medline, American College of Physicians Journal Club Database, Cochrane central register of controlled trials, Cochrane database of systematic reviews, Database of abstracts of reviews of effects. A systematic review of the literature was performed in order to compare results of randomized controlled trials and observational studies concerning changes in weight, metabolism, endocrinology, inflammatory markers and cardiovascular risk factors after suction-assisted lipectomy. All articles were assessed by criteria from Oxford Center For Evidence Based Medicine (OCEBM). RESULTS The search resulted in 40 articles: 12 experimental animal studies and 28 human studies. CONCLUSION Different metabolic parameters are affected by suction-assited lipectomy. First, all articles point out a decrease of body weight after suction-assisted lipectomy. Weight lost only affects fat mass without any change of lean mass. The potential compensatory growth of visceral fat seems to be counteracted by physical activity. Then, resting energy expenditure seems to be stable or decrease after the surgery. This reduction is significantly related to the decrease of leptin levels and also seems to be counteracted by physical activity. About adipocytokines, leptin level decreases after suction-assisted lipectomy while results are contradictory about adiponectin and resistin levels. However adiponectin seems to tend to increase after surgery. Inflammatory markers seem to increase within first hours after surgery. Then they seem to decrease or remain at the preoperative levels. Fasting insulin level decreases and is linked to the aspirated volume. So insulin sensitivity seems to be improved. Concerning lipid profil, it tends to remain the same or to be improved by suction-assisted lipectomy. In conclusion, regarding all the literature, there is still debate about metabolic effect of suction-assisted lipectomy. Prospective clinical studies are needed to confirm or invalidate some hypotheses. These studies must consider some potential biases as physical activity, diet and medical treatment modifications (statins).

Abstract
It has been postulated that the protective effects of lower body subcutaneous adipose tissue (LBSAT) occur via its ability to sequester surplus lipid and thus serve as a "metabolic sink." However, the mechanisms that mediate this protective function are unknown thus this study addresses this postulate. Ad libitum, chow-fed mice underwent Sham-surgery or LBSAT removal (IngX, inguinal depot removal) and were subsequently provided chow (Chow; typical adipocyte expansion) or high fat diet (HFD; enhanced adipocyte expansion) for 5 weeks. Primary outcome measures included glucose tolerance and subsequent insulin response, muscle insulin sensitivity, liver and muscle triglycerides, adipose tissue gene expression, and circulating lipids and adipokines. In a follow up study the consequences of extended experiment length post-surgery (13 wks) or pre-existing glucose intolerance were examined. At 5 wks post-surgery IngX in HFD-fed mice reduced glucose tolerance and muscle insulin sensitivity and increased circulating insulin compared with HFD Sham. In Chow-fed mice, muscle insulin sensitivity was the only measurement reduced following IngX. At 13 wks circulating insulin concentration of HFD IngX mice continued to be higher than HFD Sham. Surgery did not induce changes in mice with pre-existing glucose intolerance. IngX also increased muscle, but not liver, triglyceride concentration in Chow- and HFD-fed mice 5 wks post-surgery, but chow group only at 13 wks. These data suggest that the presence of LBSAT protects against triglyceride accumulation in the muscle and HFD-induced glucose intolerance and muscle insulin resistance. These data suggest that lower body subcutaneous adipose tissue can function as a "metabolic sink."

Abstract
Several epidemiologic studies have implicated visceral fat as a major risk factor for insulin resistance, type 2 diabetes mellitus, cardiovascular disease, stroke, metabolic syndrome and death. Utilizing novel models of visceral obesity, numerous studies have demonstrated that the relationship between visceral fat and longevity is causal while the accrual of subcutaneous fat does not appear to play an important role in the etiology of disease risk. Specific recommended intake levels vary based on a number of factors, including current weight, activity levels, and weight loss goals. It is discussed the need of reducing the visceral fat as a potential treatment strategy to prevent or delay age-related diseases and to increase longevity.

Abstract
Numerous epidemiologic studies have implicated abdominal obesity as a major risk factor for insulin resistance, type 2 diabetes mellitus, cardiovascular disease, stroke, metabolic syndrome and its further expression, i.e., nonalcoholic fatty liver disease and death. Using novel models of visceral obesity, several studies have demonstrated that the relationship between visceral fat and longevity is causal, while the accrual of subcutaneous fat does not appear to play an important role in the etiology of disease risk. The need of reducing the visceral fat to improve survival, mainly taking into account the strict link between nonalcoholic fatty liver disease and the coronary artery disease is discussed.

Abstract
BACKGROUND Advanced studies on adipose tissue have established that subcutaneous adipose tissue acts as an endocrine organ to help maintain homeostasis. Based on this information, many plastic surgeons have evaluated the metabolic effects of liposuction because liposuction is the most common surgical procedure in plastic surgery. Liposuction removes a substantial amount of subcutaneous fat from a specific area of the body. Mammoplasty is another procedure that removes a large amount of subcutaneous fat. In this study, the metabolic effects of reduction mammoplasty were evaluated with hemogram, blood glucose, lipid profile, insulin, and insulin resistance tests before and after surgery. METHODS The study involved 35 patients who underwent reduction mammoplasty between January 2006 and June 2009. All the patients were evaluated with physical examination and their history, height, and weight were obtained. Venous blood samples were collected before, 4 h after, and 3 months after the surgical procedure to evaluate hemogram, blood glucose, insulin, and lipid profiles. The HOMA scores of the patients were calculated. Inferiorly based dermal pedicle, central pedicle, and free nipple graft techniques were used in the operations and all excision materials were sent for histopathological examination. RESULTS The mean age of the patients was 39.6 ± 11.6 years. The mean excision volume was 2249 ± 1001 g. Body mass indexes were not significantly different before and 3 months after the surgery (p > 0.05). Blood glucose, LDL, HDL, triglyceride, total cholesterol, hemoglobin, and hematocrit values before and 4 h after the surgery were also different (p < 0.05). However, comparisons with the 3-month postoperative test results revealed no statistically significant differences (p > 0.05) and comparisons of all the measurements showed that insulin levels and HOMA scores were not significantly different (p > 0.05). CONCLUSION The results of the present study showed that reduction mammoplasty operations do not have any positive effects on blood insulin, glucose profile, lipid profile, and body mass index 3 months after the surgery.

Abstract
Liposuction is the most popular aesthetic surgery performed in Brazil and worldwide. Evidence showing that adipose tissue is a metabolically active tissue has led to the suggestion that liposuction could be a viable method for improving metabolic profile through the immediate loss of adipose tissue. However, the immediate liposuction-induced increase in the proportion of visceral to subcutaneous adipose tissue could be detrimental to metabolism, because a high proportion of visceral to subcutaneous adipose tissue is associated with risk factors for cardiovascular disease. The results of studies investigating the effects of liposuction on the metabolic profile are inconsistent, however, with most studies reporting either no change or improvements in one or more cardiovascular risk factors. In addition, animal studies have demonstrated a compensatory growth of intact adipose tissue in response to lipectomy, although studies with humans have reported inconsistent results. Exercise training improves insulin sensitivity, inflammatory balance, lipid oxidation, and adipose tissue distribution; increases or preserves the fat-free mass; and increases total energy expenditure. Thus, liposuction and exercise appear to directly affect metabolism in similar ways, which suggests a possible interaction between these two strategies. To our knowledge, no studies have reported the associated effects of liposuction and exercise in humans. Nonetheless, one could suggest that exercise training associated with liposuction could attenuate or even block the possible compensatory fat deposition in intact depots or regrowth of the fat mass and exert an additive or even a synergistic effect to liposuction on improving insulin sensitivity and the inflammatory balance, resulting in an improvement of cardiovascular risk factors. Consequently, one could suggest that liposuction and exercise appear to be safe and effective strategies for either the treatment of metabolic disorders or aesthetic purposes.

Abstract
The prevalence of obesity is increasing and with it the prevalence of associated metabolic complications. Precisely how obesity results in metabolic disturbances remains unclear. In the face of persistent positive caloric balance, it has been postulated that the capacity of adipose tissue to safely store fat may be vital. This paper explores some of the evidence suggesting that the risk of developing metabolic disturbances is not related to how much fat an individual has, but how well their fat can expand to accommodate the caloric excess. If this is true, the metabolic consequences of obesity may arise from the inability to become more obese.

Abstract
BACKGROUND The aim of this study was to determine any change in dehydroepiandrosterone (DHEA) and lipid profile in non-obese women after abdominoplasty. METHODS An auto-controlled clinical trial was carried out. 9 women aged 35 to 40 years with BMI 22-25 kg/m2 were studied. Basal lipid profile and DHEA were performed and repeated 1 month postoperatively. Statistical analysis used Wilcoxon signed-ranks test (two-tailed). RESULTS Weight of resected specimen was 606.11 +/- 143.4 grams. No significant changes were observed in high-density cholesterol (48.0 +/- 9.6 vs 48.8 +/- 11.0 mg/dl; P=0.106) or in triglycerides (119.2 +/- 50.9 vs 148.4 +/- 45.8 mg/dl; P = 0.139). Significant increases were obtained in DHEA (3.69 +/- 3.05 vs 11.09 +/- 6.3 ng/ml; P<0.008), low-density cholesterol (LDL) (87.4 +/- 23.5 vs 108.5 +/- 28.3 mg/dl; P<0.008 and total cholesterol (155.1 +/- 30.6 vs 186.6 +/- 33.1 mg/dl; P<0.008). CONCLUSION Excision of subcutaneous abdominal fat in studies 1 month later increased DHEA, whose role is controversial in visceral fat distribution, and increased LDL cholesterol and total cholesterol, both risk markers for cardiovascular illness.
