Santos LRA, da Costa PR, Maia TS, Junior AC, Resende V. Prospective cohort of parameters of glycemic and lipid metabolism after abdominoplasty in normal weight and formerly obese patiens. JPRAS Open 2023; 37:155-162. [PMID: 37560483 PMCID: PMC10407811 DOI: 10.1016/j.jpra.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 07/09/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Obesity poses a major risk for cardiovascular diseases, while it is almost a consensus that intra-abdominal adiposity has a more deleterious effect for metabolic syndrome. In this sense, it is speculated that lipectomy or liposuction would be metabolically harmful, as it changes the abdominal-superficial adipose tissue ratio. However, the literature has shown conflicting evidence. METHODS In order to evaluate the possibility of metabolism alteration resulting from body coutouring surgery, a prospective cohort was implemented with 35 patients who underwent abdominoplasty, including some with a history of massive weight loss. Fasting blood glucose, fasting plasma insulin, triglycerides, total cholesterol and fractions were requested preoperatively and in the third postoperative month. The groups were also compared with each other. RESULTS No statistically significant variation between the exams collected in the preoperative period and those collected after abdominoplasty was found. There was a statistically significant difference in LDL (low-density lipoprotein; p = 0.033) and non-HDL (non-high-density lipoprotein) cholesterol (p = 0.020) between the two control tests of the groups surveyed. There were also differences in comorbidities (p = 0.006) and complications (p <0.001) between the groups. CONCLUSIONS Abdominoplasty was not able of changing tests that assess glycemic and lipid metabolism three months after the operation. Our attention was drawn to the fact that patients who had massive weight loss had better control of LDL cholesterol (p = 0.033) and non-HDL cholesterol (p = 0.020), despite having higher weight and body mass index (p <0.001).

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
OBJECTIVE The goal of this study was to review the metabolic effects of fat transplantation. METHODS Fat (adipose tissue [AT]) transplantation has been performed extensively for many years in the cosmetic reconstruction industry. However, not all fats are equal. White, brown, and beige AT differ in energy storage and use. Brown and beige AT consume glucose and lipids for thermogenesis and, theoretically, may provide greater metabolic benefit in transplantation. Here, the authors review the metabolic effects of AT transplantation. RESULTS Removal of subcutaneous human AT does not have beneficial metabolic effects. Most studies find no benefit from visceral AT transplantation and some studies report harmful effects. In contrast, transplantation of inguinal or subcutaneous AT in mice has positive effects. Brown AT transplant studies have variable results depending on the model but most show benefit. CONCLUSIONS Many technical improvements have optimized fat grafting and transplantation in cosmetic surgery. Transplantation of subcutaneous AT has the potential for significant metabolic benefits, although there are few studies in humans or using human AT. Brown AT transplantation is beneficial but not readily feasible in humans thus ex vivo "beiging" may be a useful strategy. AT transplantation may provide clinical benefits in metabolic disorders, especially in the setting of lipodystrophy.

Abstract
Background Despite consistent interest over the past 2 decades regarding the metabolic effects of body contouring (BC), previous studies are limited by short follow-up periods, small sample sizes, gender-specific cohorts, and assessment of all anatomic regions together. Objectives This study evaluates the changes in glucose and lipid levels over long-term follow up after trunk-based BC and compares postbariatric with nonbariatric patients. Methods The retrospective cohort study included patients who underwent trunk-based BC from January 1, 2009 through July 31, 2020 at West Virginia University. A minimum 12-month follow up was required for inclusion. With BC surgery as the reference point, patients' glucose, hemoglobin A1c, and lipid levels were assessed prior to surgery and at long-term follow up. Change over time was compared between postbariatric and nonbariatric cohorts. Multivariable linear regression models were performed to assess the effect of potential confounding variables on the difference between cohorts. Results Seventy-seven BC patients had glucose levels evaluated during the study period, and 36 had lipid profiles obtained. Average follow up from date of BC was 41.2 months for the patients with glucose follow up and 40.9 months for those with lipid levels. From pre-BC to endpoint follow up, glucose levels mildly increased in all patients. Multivariable linear regression models accounting for age showed nonbariatric patients experience significantly improved total cholesterol levels compared to postbariatric patients (P = 0.0320). Weight loss maintained following BC was not associated with significant differences between cohorts. Conclusions Fasting glucose levels marginally increase in most BC patients through follow up. Nonbariatric patients generally experience more favorable changes in lipid profile following trunk-based BC than do postbariatric patients. Level of Evidence 3

Abstract
We propose a weight-neutral strategy for obesity treatment on the following grounds: (1) the mortality risk associated with obesity is largely attenuated or eliminated by moderate-to-high levels of cardiorespiratory fitness (CRF) or physical activity (PA), (2) most cardiometabolic risk markers associated with obesity can be improved with exercise training independent of weight loss and by a magnitude similar to that observed with weight-loss programs, (3) weight loss, even if intentional, is not consistently associated with lower mortality risk, (4) increases in CRF or PA are consistently associated with greater reductions in mortality risk than is intentional weight loss, and (5) weight cycling is associated with numerous adverse health outcomes including increased mortality. Adherence to PA may improve if health care professionals consider PA and CRF as essential vital signs and consistently emphasize to their patients the myriad benefits of PA and CRF in the absence of weight loss.

Abstract
Background One of the adverse effects of antiretroviral (ARV) drugs in the treatment of human immunodeficiency virus is lipodystrophy, which is often associated with metabolic complications such as hyperlipidemia, increased cardiovascular risk factors, and altered body fat distribution. This is characterized by a dorsal hump, hypermastia, or abdominal pannus deformity. The reasons for corrective surgery are aesthetic, psychosocial, and medical benefits. Methods This is a prospective study investigating 52 consecutive patients with ARV-induced lipodystrophy syndrome referred for surgical correction (liposuction for dorsal hump, abdominoplasty for increased abdominal pannus, and bilateral breast reduction for hypermastia). Fasting serum lipograms, including cholesterol, triglycerides, high-density cholesterol (HDL), and low-density cholesterol (LDL), were taken preoperatively and repeated 9-12 months post lipectomy/liposuction. Results A subgroup of 35 patients with deranged preoperative triglycerides (P = 0.004), cholesterol (P = 0.001), and or LDL cholesterol (P = 0.017) showed a statistically significant (P < 0.05) decrease in postoperative levels. If preoperative lipogram values were normal, there is no statistically significant reduction postoperatively. Conclusions In ARV-associated lipodystrophy, when the preoperative fasting lipograms are deranged, then after surgical correction there is a statistically significant reduction in triglyceride, total cholesterol, and LDL levels. This influences their cardiovascular risk profile, mortality, morbidity, and quality of life.

Abstract
BACKGROUND Weight loss is traditionally viewed as straightforward counting of calories in and calories out, with little regard to the role of the adipocytes tasked with storing said calories. However, the body executes a complex compensatory response to any intervention that depletes its energy stores. Here, the authors discuss the methods used to attain weight loss, the body's response to this weight loss, and the difficulties in maintaining weight loss. Furthermore, the authors provide an overview of the literature on the physiological effects of liposuction. OBJECTIVE To describe the role of adipose tissue in energy homeostasis, methods of weight loss, weight regain, and the effect of liposuction on endocrine signaling. METHODS The authors conducted a narrative review of representative studies. CONCLUSION A variety of strategies for weight loss exist, and optimizing one's weight status may in turn optimize the aesthetic outcomes of liposuction. This is most apparent in the preferential reaccumulation of fat in certain areas after liposuction and the ability to avoid this with a negative energy balance.

Abstract
INTRODUCTION Meta-analyses are considered to be an important source of evidence. This review aims to systematically assess the quality of meta-analyses addressing topics in plastic surgery. METHODS Electronic databases were selected for systematic review. A search was performed focusing on communication addresses containing terms related to plastic surgery, and detailed inclusion criteria were used. Related data were extracted and recorded according to the items of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. To assess the quality of the meta-analyses over time, studies published before and after PRISMA were evaluated. RESULTS A total of 116 meta-analyses were included. There was 1 study that was fully in compliance with the PRISMA items. The main flaws impacting the overall quality of the included studies were in the following areas: structured summary (48%), protocol and registration (2%), full electronic search strategy (35%), risk of bias in individual studies (41%), additional analyses (27%), risk of bias within studies (47%), additional analysis (30%), and funding (47%). Study quality was evaluated using relative risks (RR) with a 95% confidence interval (95% CI); this revealed that there were few significant improvements in adherence to the PRISMA statement after its release, especially in selection (RR, 1.80; 95% CI, 1.08-2.99), results of individual studies (RR, 2.88; 95% CI, 1.41-5.91), synthesis of results (RR, 3.08; 95% CI, 1.32-7.17), and funding (RR, 1.65; 95% CI, 1.21-2.24). CONCLUSIONS There have been measurable improvements in the quality of meta-analyses over recent years. However, several serious deficiencies remain according to the PRISMA statement. Future reviewers should pay more attention to not only reporting the main findings but also encouraging compliance with proper standards.

Abstract
OBJECTIVE To assess the effectiveness of low-level laser therapy (LLLT) for reducing hip, thigh, and abdomen circumference of individuals with body-mass index (BMI) between 30 and 40 kg/m2. BACKGROUND Previous studies demonstrated the effectiveness of LLLT for reducing body circumference in the hips, thighs, and abdomen of nonobese individuals with a BMI <30 kg/m2. METHODS In this randomized, double-blind sham-controlled study, obese, but otherwise healthy, individuals were randomized to undergo 30-min LLLT (n = 28) or sham treatments (n = 25) three times weekly for 4 weeks. Body measurements were obtained after 2 and 4 weeks of treatment and 2 weeks post-treatment ( ClinicalTrials.gov Identifier: NCT01821352). RESULTS After 4 weeks, 20 LLLT-treated subjects (71.43%) achieved ≥7.2 cm decrease in combined measurements versus three sham-treated subjects (12%; p < 0.00005). The mean (standard deviation) decrease in combined measurement for LLLT-treated subjects was 10.52 (7.59) cm (p < 0.0001 vs. baseline) versus 1.80 (3.20) cm for sham-treated subjects. Among subjects with a combined ≥7.2 cm decrease, the mean total decrease 2 weeks post-treatment was 15.21 cm. There were no adverse events. CONCLUSIONS Based on these results, the device was cleared by the U.S. Food and Drug Administration as a noninvasive esthetic treatment for reduction of circumference of hips, waist, and upper abdomen when applied to individuals with a BMI between 30 and 40 kg/m2.

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
BACKGROUND Adipose tissue is an endocrine organ, which is implicated in the pathogenesis of obesity, metabolic syndrome and diabetes. Lipectomy offers a unique opportunity to permanently reduce the absolute number of fat cells, though its functional role remains unclear. This systematic and meta-analysis review aims to assess the effect of abdominal lipectomy on metabolic syndrome components and insulin sensitivity in women. METHODS A predetermined protocol, established according to the Cochrane Handbook's recommendations, was used. An electronic search in MEDLINE, Scopus, the Cochrane Library and CENTRAL electronic databases was conducted from inception to May 14, 2015. This search was supplemented by a review of reference lists of potentially eligible studies and a manual search of key journals in the field of plastic surgery. Eligible studies were prospective studies with ≥1month of follow-up that included females only who underwent abdominal lipectomy and reported on parameters of metabolic syndrome and insulin sensitivity. RESULTS The systematic review included 11 studies with a total of 271 individuals. Conflicting results were revealed, though most studies showed no significant metabolic effects after lipectomy. The meta-analysis included 4 studies with 140 subjects. No significant changes were revealed between lipectomy and control groups. CONCLUSIONS This meta-analysis provides evidence that abdominal lipectomy in females does not affect significantly the components of metabolic syndrome and insulin sensitivity. Further high quality studies are needed to elucidate the potential metabolic effects of abdominal lipectomy. Systematic review registration PROSPERO CRD42015017564 (www.crd.york.ac.uk/PROSPERO).

Abstract
Obesity is associated with many pathological conditions. Tumor Necrosis Factor-α (TNF-α) is one of the key mediators of inflammation involved in the obesity-related insulin resistance development. We aim to review the human evidence useful to clarify the relationship between inflammation and body weight, with particular reference to TNF-α. Genetic polymorphisms and epigenetic factors, such as diet, could affect TNF-α activity. TNF-α is associated with obesity, but also with anorexia and cachexia. Despite the role of TNF-α in obesity-related diseases, anti-TNF-α antibody therapy is associated with an increase in adiposity. In conclusion the reviewed results suggest that inflammation is more likely a consequence rather than a cause of obesity.
