Insulin in combination with pioglitazone prevents advanced cachexia in 256-Walker tumor-bearing rats: effect is greater than treatment alone and is associated with improved insulin sensitivity. Pharmacol Rep 2023; 75:1571-1587. [PMID: 37804392 DOI: 10.1007/s43440-023-00533-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 09/15/2023] [Accepted: 09/18/2023] [Indexed: 10/09/2023]
Abstract
BACKGROUND Insulin (INS) resistance and hypoinsulinemia commonly observed in cancer-carrying, can contribute to cachexia. However, the effects of INS and INS sensitizers, such as pioglitazone (PIO), particularly when used in combination therapy, on cancer cachexia have not been evaluated sufficiently. We investigated the effects of INS and PIO, at various doses, either isolated or combined, on cachexia in Walker-256 tumor-bearing rats (TB rats). METHODS INS or INS + PIO were administered in TB rats, for 6 or 12 days, starting from the day of tumor cells inoculation. RESULTS INS at 18 or 27 U/kg (12-days treatment), but not 9 U/kg, reduced fat loss and slightly prevented weight loss. However, INS 18 U/kg + PIO 5, 10, 20, or 40 mg/kg (6 or 12-day treatment) reduced fat loss and markedly prevented weight loss but did not affect muscle wasting. While TB rats lost weight (37.9% in 12 days), TB rats treated with INS 18 U/kg + PIO 5 mg/kg showed pronounced weight gain (73.7%), which was greater than the sum (synergism) of the weight gains promoted by isolated treatments with INS 18 U/kg (14.7%) or PIO 5 mg/kg (13.1%). The beneficial effect of the INS 18 U/kg + PIO 5 mg/kg on weight loss was associated with improved INS sensitivity, as indicated by the higher blood glucose clearance constant (kITT), decreased levels of free fatty acids and triacylglycerols (INS resistance-inducing factors) in the blood, and increased expression of p-Akt (INS signaling pathway protein) in adipose tissue. CONCLUSIONS The combined treatment with INS 18 U/kg + PIO 5 mg/kg was more effective in preventing advanced cachexia in TB rats than each treatment alone, emerging as the best approach, considering the lower dosage and higher efficacy. This combination completely preserved adipose mass and markedly reduced weight loss through a synergistic mechanism linked to improved insulin sensitivity. These findings provide new insights into the importance of drug combinations in effectively combating fat loss in advanced cachexia.

Intrauterine food restriction impairs the lipogenesis process in the mesenteric adipocytes from low-birth-weight rats into adulthood. Front Endocrinol (Lausanne) 2023; 14:1259854. [PMID: 38027196 PMCID: PMC10651082 DOI: 10.3389/fendo.2023.1259854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 10/09/2023] [Indexed: 12/01/2023] Open
Abstract
Background Intrauterine food restriction (IFR) during pregnancy is associated with low birth weight (LBW) and obesity in adulthood. It is known that white adipose tissue (WAT) plays critical metabolic and endocrine functions; however, this tissue's behavior before weight gain and obesity into adulthood is poorly studied. Thus, we evaluated the repercussions of IFR on the lipogenesis and lipolysis processes in the offspring and described the effects on WAT inflammatory cytokine production and secretion. Methods We induced IFR by providing gestating rats with 50% of the necessary chow daily amount during all gestational periods. After birth, we monitored the offspring for 12 weeks. The capacity of isolated fat cells from mesenteric white adipose tissue (meWAT) to perform lipogenesis (14C-labeled glucose incorporation into lipids) and lipolysis (with or without isoproterenol) was assessed. The expression levels of genes linked to these processes were measured by real-time PCR. In parallel, Multiplex assays were conducted to analyze pro-inflammatory markers, such as IL-1, IL-6, and TNF-α, in the meWAT. Results Twelve-week-old LBW rats presented elevated serum triacylglycerol (TAG) content and attenuated lipogenesis and lipolysis compared to control animals. Inflammatory cytokine levels were increased in the meWAT of LBW rats, evidenced by augmented secretion by adipocytes and upregulated gene and protein expression by the tissue. However, there were no significant alterations in the serum cytokines content from the LBW group. Additionally, liver weight, TAG content in the hepatocytes and serum glucocorticoid levels were increased in the LBW group. Conclusion The results demonstrate that IFR throughout pregnancy yields LBW offspring characterized by inhibited lipogenesis and lipolysis and reduced meWAT lipid storage at 12 weeks. The increased serum TAG content may contribute to the augmented synthesis and secretion of pro-inflammatory markers detected in the LBW group.

Abstract
Photobiomodulation therapy (PBMT) has become an adjuvant therapeutic possibility in body remodeling procedures. Given this scenario, this study was proposed with the aim of evaluating the effects of PBMT to Light Emitting Diode (LED) associating the red (630 nm) and infrared (850 nm) wavelengths in the subcutaneous fatty tissue. This controlled study of comparative intervention that evaluated a sample of subcutaneous fatty tissue from women with grade II obesity. The participants received the LED PBMT treatment with associated red and infrared wavelengths sequentially on the left side of the abdomen and the right side was considered as control, with the collection of biological material performed at the time of bariatric surgery. For histological and immunohistochemical evaluation, Caspase 3, Cleaved Caspase 3, CD68+, HSL and adipophilin markers were used. The participants showed positivity in the expression of Caspase 3 and Cleaved Caspase (p < .0001), CD68+ macrophages (p < .0001), HSL (p < .0001) and adipophilin (p < .0013) in the intervention sample when compared to the control. PBMT and LED associating red and infrared wavelengths were able to promote autophagic lipolysis induced by adipocyte cell apoptosis in the subcutaneous tissue of obese individuals.

Abstract
Simple Summary Adipocytes or fat cells are integral part of the ovarian tumor microenvironment. Secreted factors from adipocytes, as well as direct cell-to-cell interaction with ovarian cancer cells have been shown to directly support ovarian tumor progression. Elucidating the molecular pathways involved is crucial in the identification of relevant targets. Abstract The tumor microenvironment of ovarian cancer is the peritoneal cavity wherein adipose tissue is a major component. The role of the adipose tissue in support of ovarian cancer progression has been elucidated in several studies from the past decades. The adipocytes, in particular, are a major source of factors, which regulate all facets of ovarian cancer progression such as acquisition of chemoresistance, enhanced metastatic potential, and metabolic reprogramming. In this review, we summarize the relevant studies, which highlight the role of adipocytes in ovarian cancer progression and offer insights into unanswered questions and possible future directions of research.

Abstract
The desire to reduce and remodel undesirable fatty deposits has increased the popularity and use of aesthetic procedures, among them, cryolipolysis. However, repercussions on the autonomic nervous system must be considered, since the decrease in cutaneous body temperature can have repercussions on sympathetic and parasympathetic components. The aim was to evaluate the behavior of cardiac autonomic modulation during and after a single application of cryolipolysis. A single-arm, prospective interventional study evaluated data from 13 women with a mean age of 22.38 ± 2.95 years, who had an accumulation of abdominal fat of at least 1.5 mm, were using oral contraceptives, and were sedentary. A professional applied cryolipolysis in a single 40-min session. RR intervals were collected by means of a cardiofrequency meter, at rest prior to the technique for 10 min, during the performance of the technique, and immediately after the end of the technique for a period of 50 min. Heart rate variability (HRV) analysis was performed using time, frequency, and Poincaré plot indices. For the mean RR, SDNN, rMSSD, SD1, SD2, and LF [ms2] indices, the values increased during the execution of cryolipolysis when compared to rest. In the recovery period, increases in the mean values of the RR, SDNN, rMSSD, SD1, SD2, HF [ms2], LF [nu], and HF [nu] indices were also observed when compared to the baseline moment. Both during the technique and in the recovery period, there were changes in the behavior of HRV characterized by an increase in global and vagal indices.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Parkinsonia aculeata L. (Cesalpineaceae) is a medium tree found in the Xingó region (semi-arid area) in Northeast of Brazil, recognised by local population as an antidiabetic agent. According information from local community, the commonly traditional preparation is prepared as an infusion of the aerial part of the plant and consumed over the day to manage diabetes-related complications. Previous studies have described Parkinsonia aculeate as a product with both hypoglycemic and hypotriglyceridemic effects. AIM OF THE STUDY The objective of this study was to evaluate the effects of polar fraction obtained from the hydroethanolic extract of Parkinsonia aculeata (PfrHEPA) on the lipid profile of animals that consumed a westernized diet. MATERIALS AND METHODS Thirty-six Wistar rats (45-55 g) were fed either with standard control(C) or westernized diet(W) for 120 days. The food intake, body weight evolution and body size were also analyzed. From 120 to 150 days, they were orally treated according to their group with vehicle (distillated water, 10 mL/kg), PfrHEPA at three doses (35, 70 and 140 mg/kg/day) or Gemfibrozil (140 mg/kg/day) for 30 days. RESULTS The animals fed with westernized diet showed dyslipidemia when compared to animals receiving a standard diet. Treatment with PfrHEPA (140 mg/kg), even with the continued consumption of westernized diet by animals (from 120 to 150 days) promoted a significant reduction in total cholesterol, LDL and triglyceride levels, in relation to untreated W group. PfrHEPA 140 mg/kg reduced the key serum lipids and glycaemia as well as inflammatory cytokines known as important risk factors of cardiovascular diseases. CONCLUSIONS The observed evidence may contribute to the control of metabolic parameters as dyslipidemia corroborating the ethnopharmacological information concerning the antihyperlipidemic and hypoglycemic activities of P. aculeata.

Abstract
Resveratrol is a phytoalexin with multiple bioactive properties, including antioxidative, neuroprotective, cardioprotective, and anticancer effects. However, resveratrol exhibits structural instability in response to UV irradiation, alkaline pH, and oxygen exposure. Thus, resveratrol derivatives have attracted considerable research interest. In this study, we aimed to evaluate the anti-adipogenic effects of pinostilbene hydrate (PH), a methylated resveratrol derivative, in 3T3-L1 cells. We also evaluated the mechanisms underlying the effects of PH on adipogenesis in 3T3-L1 adipocytes. Oil Red O staining, lipid accumulation assay, and triglyceride (TG) content assay revealed that PH significantly inhibited lipid and TG accumulation without cytotoxicity. In addition, we determined that PH decreased the expression of adipogenesis-related transcription factors, such as PPARγ, C/EBPα, SREBP-1c, and FABP4, and the phosphorylation of MAPK and protein kinase B (AKT). Moreover, PH attenuated the expression of CREB and C/EBPβ, while increasing the phosphorylation of AMPK and ACC, and decreasing the expression of fatty acid synthase and FABP4. Based on these results, we suggest that PH suppresses adipogenesis in 3T3-L1 cells via the activation of the AMPK signaling pathway and the inhibition of the MAPK and AKT insulin-dependent signaling pathways.

Abstract
This study aimed to investigate the effects of two commercially available fish oils (FOs) containing different proportions of two omega-3 fatty acids (FA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), on the metabolic and endocrine dysfunctions of white adipose tissue resulting from obesity. Male C57BL/6J mice, 8 weeks old, received a control or high-fat diet (CO and HF groups, with 9% and 59% energy from fat, respectively) for 8 weeks. The next 8 weeks, the HF group was subdivided into HF, HF+FO/E (HF+5:1 EPA:DHA), and HF+FO/D (HF+5:1 DHA:EPA). Supplementation was performed by gavage, three times a week. All groups that received the HF diet had lower food and caloric intake, but a higher fat intake, body weight (BW) gain, glucose intolerance, and a significant increase in inguinal (ING), retroperitoneal (RP), and epididymal (EPI) adipose tissues when compared to the CO group. Additionally, HF and HF+FO/D groups showed insulin resistance, adipocyte hypertrophy, increased lipolysis and secretion of TNF-α, resistin and IL-10 adipokines by ING and RP adipocytes, and adiponectin only by the HF+FO/D group in ING adipocytes. All of these effects were completely reversed in the HF+FO/E group, which also showed partial reversion in BW gain and glucose intolerance. Both the HF+FO/E and HF+FO/D groups showed a reduction in ING and RP adipose depots when compared to the HF group, but only HF+FO/E in the EPI depot. HF+FO/E, but not HF+FO/D, was able to prevent the changes triggered by obesity in TNF-α, Il-10, and resistin secretion in ING and RP depots. These results strongly suggest that different EPA:DHA ratios have different impacts on the adipose tissue metabolism, FO being rich in EPA, but not in DHA, and effective in reversing the changes induced by obesity.

Abstract
This study aimed to determine whether body fat distribution and physical fitness would be associated with risk factors for cardiovascular diseases (CVDs) in post-menopausal females. Android fat distribution were more likely to have altered total cholesterol (TC), high-density lipoprotein (HDL-C), triglycerides (TG), glycemic levels (GL) body fat percentage (%BF), and body mass index (BMI), and those with inadequate physical fitness showed clear alterations in TC, HDL-C, and TG. Gynoid fat distribution group fared better regarding CVD risk. In conclusion, adequate physical fitness demonstrates a protective factor against CVDs, with the greatest benefit to those with gynoid fat distribution.

Genome-wide association study and pathway analysis for fat deposition traits in nellore cattle raised in pasture-based systems. J Anim Breed Genet 2020; 138:360-378. [PMID: 33232564 DOI: 10.1111/jbg.12525] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 10/30/2020] [Accepted: 11/01/2020] [Indexed: 02/06/2023]
Abstract
Genome-wide association study (GWAS) is a powerful tool to identify candidate genes and genomic regions underlying key biological mechanisms associated with economically important traits. In this context, the aim of this study was to identify genomic regions and metabolic pathways associated with backfat thickness (BFT) and rump fat thickness (RFT) in Nellore cattle, raised in pasture-based systems. Ultrasound-based measurements of BFT and RFT (adjusted to 18 months of age) were collected in 11,750 animals, with 39,903 animals in the pedigree file. Additionally, 1,440 animals were genotyped using the GGP-indicus 35K SNP chip, containing 33,623 SNPs after the quality control. The single-step GWAS analyses were performed using the BLUPF90 family programs. Candidate genes were identified through the Ensembl database incorporated in the BioMart tool, while PANTHER and REVIGO were used to identify the key metabolic pathways and gene networks. A total of 18 genomic regions located on 10 different chromosomes and harbouring 23 candidate genes were identified for BFT. For RFT, 22 genomic regions were found on 14 chromosomes, with a total of 29 candidate genes identified. The results of the pathway analyses showed important genes for BFT, including TBL1XR1, AHCYL2, SLC4A7, AADAT, VPS53, IDH2 and ETS1, which are involved in lipid metabolism, synthesis of cellular amino acids, transport of solutes, transport between Golgi Complex membranes, cell differentiation and cellular development. The main genes identified for RFT were GSK3β, LRP1B, EXT1, GRB2, SORCS1 and SLMAP, which are involved in metabolic pathways such as glycogen synthesis, lipid transport and homeostasis, polysaccharide and carbohydrate metabolism. Polymorphisms located in these candidate genes can be incorporated in commercial genotyping platforms to improve the accuracy of imputation and genomic evaluations for carcass fatness. In addition to uncovering biological mechanisms associated with carcass quality, the key gene pathways identified can also be incorporated in biology-driven genomic prediction methods.

Abstract
Obesity is characterized by a low degree of chronic inflammation state that, along with metabolic modifications, promotes important changes in the animal's organism. Adipose tissue actively participates in inflammation and immunity, and several defense cells of the organism may, therefore, be involved in the diversity found between obese and ideal weight individuals. Studies regarding this subject have shown immune cell changes in humans and rats, however, the literature is scarce in relation to dogs. Thus, the present study aimed to evaluate the gene expression profile of immunoinflammatory response and the lymphoproliferation of obese dogs before and after weight loss. Eight female dogs, neutered, of different breeds, aged between 1 and 8 years (4.74±3.19), obese, with body condition score (BCS) of 9 out of a 9-point scale and body composition determined by the deuterium isotope dilution method were included. The obese dogs were enrolled in a weight loss program and after losing 20% of their initial weight became a second experimental group. A third experimental group consisted of eight female dogs, neutered, aged between 1 and 8 years (3.11±0.78) and with ideal BCS (5 out of a 9-point scale). Gene expression of immunoinflammatory cytokines (resistin, leptin, adiponectin, TNF-α, IL-6, IL-8, and IL-10) was assessed by qRT-PCR and immunity was assessed by lymphoproliferative response using the flow cytometry technique. The data that presented normal distribution was evaluated by analysis of variance by the PROC MIXED of the SAS and when differences were detected, these were compared by the Tukey test. Regarding the gene expression data, the procedure PROC GLIMMIX was adopted and the methodology of generalized linear model was used, in which the Gama distribution proved to be adequate. Values of p<0.05 were considered significant. The mean weight loss period of the animals included in the study was 194.25 ± 28.31 days and the mean weekly weight loss rate was 1.02 ± 0.82%. The average fat mass, both in percentage (P<0.001) and in kilograms (P = 0.012), was higher in the obese group (40.88%; 8.91kg), returning to normal and without difference between the control group (19.16%; 3.01kg) and after weight loss (22.10%; 4.11kg). The weight loss program resulted in an increase in percentage of lean body mass (P = 0.001), 55.50% in obese animals vs 77.90% in obese dogs after weight loss, the latter with no difference when compared to the control group (80.84%). The obese group presented increased gene expression of resistin and IL-8 in relation to the weight loss group (P = 0.002). In adiponectin, the obese group presented increased mRNA gene expression when compared to the weight loss group (P = 0.003). The evaluation of lymphocyte proliferation showed differences between the group of obese animals before and after weight loss (P = 0.004). Weight loss resulted in an increase in the lymphoproliferation rate (18.48%) compared to obese dogs at the beginning of the study (10.71%). These results indicate that weight loss modulates the immunoinflammatory response of obese dogs and may present important benefits to health and longevity of dogs.

Abstract
Literature describes breast milk as the best food for the newborn, recommending exclusive breastfeeding for up to 6 months of age. However, it is not available for more than 40% of children worldwide. Pharmacological and non-pharmacological models of 3-day early weaning were developed in rodents to investigate later outcomes related solely to this nutritional insult. Thus, the present work aimed to describe biometric, nutritional, biochemical, and cardiovascular outcomes in adult male rats submitted to 3-day early weaning achieved by maternal deprivation. This experimental model comprises not only nutritional insult but also emotional stress, simulating mother abandoning. Male offspring were physically separated from their mothers at 21st (control) or 18th (early weaning) postnatal day, receiving water/food ad libitum. Analysis performed at postnatal days 30, 90, 150, and 365 encompassed body mass and food intake monitoring and serum biochemistry determination. Further assessments included hemodynamic, echocardiographic, and cardiorespiratory evaluation. Early-weaned males presented higher body weight when compared to control as well as dyslipidemia, higher blood pressure, diastolic dysfunction, and cardiac hypertrophy in adult life. Animals early deprived of their mothers have also presented a worse performance on the maximal effort ergometer test. This work shows that 3-day early maternal deprivation favors the development of cardiovascular disease in male rats.

Abstract
Introduction Objective: the purpose of this study was to investigate the effects of Chrysobalanus icaco on adiposity and its mechanism of action in the gene and protein expression of acetyl-CoA carboxylase (ACC), a key enzyme in lipogenesis. Method: Wistar rats were divided into a regular or control group (CG) and a high-fat diet (HFD) group. HFD was treated with saline or aqueous extract of Chrysobalanus icaco (AECI) for four weeks. Body weight and food intake were assessed. Subcutaneous, retroperitoneal and periepididymal adipose tissue samples were collected and weighed. Adipocytes from periepididymal tissue were isolated and analyzed. The gene and protein expression of ACC in subcutaneous tissue was determined. Results: AECI showed no effect on intake or body weight. However, the weight of the fat pads and the gene and protein expression of ACC were lower, and glucose tolerance was improved. Conclusion: the aqueous extract of Chrysobalanus icaco proved beneficial for the treatment of obesity, preventing fat storage and improving glycemic homeostasis.

Abstract
Background Elevated chemerin level is observed in patients with arterial hypertension. The aim of the study was to determine the relationship between chemerin level, and parameters of blood pressure and arterial stiffness in children and adolescents with obesity but without arterial hypertension. Methods In 23 children with obesity (13 girls, mean age 9.3, SD 1.9, mean BMI SDS 3.9, SD 1.7) 24 h ABPM (Spacelabs 90,217, USA), common carotids and abdominal aorta intima media thickness measurements (Voluson 730, GE Medical System 8.5 and 3.5 MHz probes), body composition analysis (Tanita BC 418 S MA, Tokyo, Japan) were performed. Glucose, triglycerides, total, LDL and HDL cholesterol, liver enzymes, uric acid, creatinine, sodium, insulin and chemerin levels were assessed in blood sample taken after a 12-h fasting period. Results There was a significant correlation of circulating chemerin level with systolic blood pressure load in ABPM (r=0.5, p<0.05). Conclusion Elevated chemerin level may be associated with increased systolic blood pressure in obese children.

Abstract
We investigate the effects of aerobic exercise training (AET) on the thermogenic response, substrate metabolism and renin angiotensin system (RAS) in the subcutaneous white adipose tissue (SC-WAT) of mice fed cafeteria diet (CAF). Male C57BL/6J mice were assigned into groups CHOW-SED (chow diet, sedentary; n = 10), CHOW-TR (chow diet, trained; n = 10), CAF-SED (CAF, sedentary; n = 10) and CAF-TR (CAF, trained; n = 10). AET consisted in running sessions of 60 min at 60% of maximal speed, five days per week for eight weeks. The CAF-SED group showed higher body weight and adiposity, glucose intolerance and insulin resistance (IR), while AET prevented such damages in CAF-TR group. AET reduced the p-AKT/t-AKT ratio and increased ATGL expression in CHOW-TR and CAF-TR groups and increased t-HSL and p-HSL/t-HSL ratio in CAF-TR. AET prevented adipocyte hypertrophy in CAF-TR group and increased UCP-1 protein expression only in CHOW-TR. Serum ACE2 increased in CHOW-TR and CAF-TR groups, and Ang (1–7) increased in the CHOW-TR group. In the SC-WAT, CAF-TR group increased the expression of AT1, AT2 and Mas receptors, whereas CHOW-TR increased Ang (1–7) and Ang (1–7)/Ang II ratio in SC-WAT. No changes were observed in ACE and Ang II. Positive correlations were observed between UCP-1 and kITT (r = 0.6), between UCP-1 and Ang (1–7) concentration (r = 0.6), and between UCP-1 and Ang (1–7)/Ang II ratio (r = 0.7). In conclusion, the AET prevented obesity and IR, reduced insulin signaling proteins and increased lipolysis signaling proteins in the SC-WAT. In addition, the CAF diet precludes the AET-induced thermogenic response and the partial modulation of the RAS suggests that the protective effect of AET against obesity and IR could not be associated with SC-WAT RAS.

Abstract
The purpose of this study was to investigate the differences in plasma concentrations of adipokines in pregnant women with varying body mass indices (BMIs) with every trimester. In this study, 89 pregnant women were recruited. These women were divided into lean, normal, and overweight/obese groups. Serum levels of adiponectin, resistin, leptin, and visfatin were measured in the first, second, and third trimesters. In the overweight/obese group, adiponectin, resistin, and visfatin concentrations were not significantly affected by advanced gestational age. Leptin concentrations in the third trimester were significantly higher than those in the first and second trimesters. Adiponectin concentrations in the overweight/obese group were significantly lower than those in the lean group in the first and second trimesters. Visfatin concentrations in the overweight/obese group were significantly higher than those in the normal group in the first trimester. Leptin concentrations in the overweight/obese group were significantly higher than those in the lean and normal groups in all trimesters. In the first trimester, the largest differences were observed between the overweight/obese group compared to the lean and normal group. The changes in adipokines in overweight/obese groups are different from those in lean and normal groups.

Abstract
INTRODUCTION Obese patients have increased leptin production and selective resistance to its central anti-adipogenic effects, yet its pro-inflammatory immunostimulating effects persist. MATERIAL AND METHODS In a group of 70 patients who underwent primary kidney transplantation (KT) we examined adiponectin and leptin levels at the time of KT and 6 months post-transplantation. Patients with diabetes mellitus type 1 or type 2 at the time of KT were excluded from the study. RESULTS We found that leptin levels significantly increased during the post-transplant period (P = 0.0065). Overall, leptin levels were positively correlated with the level of triacylglycerols, post-transplant diabetes mellitus (PTDM) development and acute rejection (AR). We discovered that, in particular, high leptin levels were associated with AR [OR 2.1273; 95% CI 1.0130-4.4671 (P = 0.0461)] and PTDM development [OR 7.200; 95% CI 1.0310-50.2836 (P = 0.0465)], whereas, low adiponectin levels represent a risk factor for the development of insulin resistance [HR 38.6135; 95% CI 13.3844-67.7699 (P < 0.0001)] and obesity [HR 3.0821; 95% CI 0.8700-10.9192 (P = 0.0053)]. CONCLUSION We found that a high serum concentration of leptin before KT is associated with both PTDM development and AR and merits further investigation in relation to KT.

Abstract
This study evaluated the effect of the consumption of different levels and sources of lipids on metabolic parameters of Wistar rats. Animals were fed with high-fat diet (HFD) containing 20% of lard for 12 weeks to cause metabolic obesity. Subsequently, the animals were divided into six groups and were fed diets with lipid concentrations of 5% or 20% of lard (LD), soybean oil (SO) or fish oil (FO), for 4 weeks. Data were submitted to analysis of variance (two-way) followed by Tukey post hoc test (p < 0.05). The groups that consumed FO showed less weight gain and lower serum levels of triacylglycerol (TAG), total cholesterol and fractions, aspartate aminotransferase (AST) activity, atherogenic index, less amount of fat in the carcass, decreased Lee index and lower total leukocyte counting (p < 0.05). These same parameters were higher in LD treatment (p < 0.05). In the concentration of 20%, carcass fat content, blood glucose levels, as well as alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) decreased in FO groups (p < 0.05). The SO group had intermediate results regarding the other two treatments (FO and LD). We concluded that fish oil intake was able to modulate positively the metabolic changes resulting from HFD.

Cardiotrophin-1 Regulates Adipokine Production in 3T3-L1 Adipocytes and Adipose Tissue From Obese Mice. J Cell Physiol 2017; 232:2469-2477.

Abstract
Cardiotrophin-1 (CT-1) belongs to the IL-6 family of cytokines. Previous studies of our group revealed that CT-1 is a key regulator of glucose and lipid metabolism. The aim of the present study was to analyze the in vitro and in vivo effects of CT-1 on the production of several adipokines involved in body weight regulation, nutrient metabolism, and inflammation. For this purpose, 3T3-L1 adipocytes were incubated with recombinant protein CT-1 (rCT-1) (1-40 ng/ml) for 1 and 18 h. Moreover, the acute effects of rCT-1 administration (0.2 mg/kg, i.v.) for 30 min and 3 h on adipokines levels were also evaluated in high-fat fed obese mice. In 3T3-L1 adipocytes, rCT-1 treatment downregulated the expression and secretion of leptin, resistin, and visfatin. However, rCT-1 significantly stimulated apelin mRNA and secretion. rCT-1 (18 h) also promoted the activation by phosphorylation of AKT, ERK 1/2, and STAT3. Interestingly, pre-treatment with the PI3K inhibitor LY294002 reversed the stimulatory effects of rCT-1 on apelin expression, suggesting that this pathway could be mediating the effects of rCT-1 on apelin production. In contrast, acute administration of rCT-1 (30 min and 3 h) to diet-induced obese mice downregulated leptin and resistin, without significantly modifying apelin or visfatin mRNA in adipose tissue. Furthermore, CT-1 null mice exhibited altered expression of adipokines in adipose tissue. The present study demonstrates that rCT-1 modulates the production of adipokines in vitro and in vivo, suggesting that the regulation of the secretory function of adipocytes could be involved in the metabolic actions of this cytokine.

Abstract
OBJECTIVE To analyze the relationship between the peripheral blood white cells, metabolic changes, and nutritional status of adolescents with and without excess weight and body fat. METHODS This cross-sectional study evaluated the body mass index (BMI) and percentage body fat (%BF) in 362 adolescents from 15 to 19 years of age, of both sexes. White blood cell count, platelet count, uric acid, fasting glucose, insulin, and lipid profile were measured. The inclusion criteria were agreement to participate in the study and signature of the informed consent. Exclusion criteria were: presence of chronic or infectious disease; use of medications that could cause changes in biochemical tests; pregnancy; participation in weight reduction and weight control programs; use of diuretics and laxatives; or the presence of a pacemaker. The following statistical tests were applied: Kolmogorov-Smirnov test, Student's t or Mann-Whitney test, Pearson or Spearman correlation tests, and chi-squared test, considering p<0.05. RESULTS Overweight was observed in 20.7% of adolescents. The total cholesterol (TC) had a higher percentage of inadequacy (52.2%), followed by high-density lipoprotein (HDL) (38.4%). There was a positive correlation between white cells and serum lipids, insulin, body fat, and BMI. Monocytes were negatively correlated with BMI, and rods with BMI, body fat, and insulin. CONCLUSIONS Nutritional status is related to an inflammatory process, and adolescents with excess weight or body fat presented higher amounts of white blood cells.

Abstract
Numerous studies address the physiology of adipose tissue (AT). The interest surrounding the physiology of AT is primarily the result of the epidemic outburst of obesity in various contemporary societies. Briefly, the two primary metabolic activities of white AT include lipogenesis and lipolysis. Throughout the last two decades, a new model of AT physiology has emerged. Although AT was considered to be primarily an abundant energy source, it is currently considered to be a prolific producer of biologically active substances, and, consequently, is now recognized as an endocrine organ. In addition to leptin, other biologically active substances secreted by AT, generally classified as cytokines, include adiponectin, interleukin-6, tumor necrosis factor-alpha, resistin, vaspin, visfatin, and many others now collectively referred to as adipokines. The secretion of such biologically active substances by AT indicates its importance as a metabolic regulator. Cell turnover of AT has also recently been investigated in terms of its biological role in adipogenesis. Consequently, the objective of this review is to provide a comprehensive critical review of the current literature concerning the metabolic (lipolysis, lipogenesis) and endocrine actions of AT.

Abstract
The aim of this study was to analyze body fat anthropometric equations and electrical bioimpedance analysis (BIA) in the prediction of cardiovascular risk factors in eutrophic and overweight adolescents. 210 adolescents were divided into eutrophic group (G1) and overweight group (G2). The percentage of body fat (% BF) was estimated using 10 body fat anthropometric equations and 2 BIA. We measured lipid profiles, uric acid, insulin, fasting glucose, homeostasis model assessment-insulin resistance (HOMA-IR), and blood pressure. We found that 76.7% of the adolescents exhibited inadequacy of at least one biochemical parameter or clinical cardiovascular risk. Higher values of triglycerides (TG) (P = 0.001), insulin, and HOMA-IR (P < 0.001) were observed in the G2 adolescents. In multivariate linear regression analysis, the % BF from equation (5) was associated with TG, diastolic blood pressure, and insulin in G1. Among the G2 adolescents, the % BF estimated by (5) and (9) was associated with LDL, TG, insulin, and the HOMA-IR. Body fat anthropometric equations were associated with cardiovascular risk factors and should be used to assess the nutritional status of adolescents. In this study, equation (5) was associated with a higher number of cardiovascular risk factors independent of the nutritional status of adolescents.

Abstract
Adipose tissue is no longer considered to be an inert tissue that stores fat. This tissue is capable of expanding to accommodate increased lipids through hypertrophy of existing adipocytes and by initiating differentiation of pre-adipocytes. Adipose tissue metabolism exerts an impact on whole-body metabolism. As an endocrine organ, adipose tissue is responsible for the synthesis and secretion of several hormones. These are active in a range of processes, such as control of nutritional intake (leptin, angiotensin), control of sensitivity to insulin and inflammatory process mediators (tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), resistin, visfatin, adiponectin, among others) and pathways (plasminogen activator inhibitor 1 (PAI-1) and acylation stimulating protein (ASP) for example). This paper reviews some of the biochemical and metabolic aspects of adipose tissue and its relationship to inflammatory disease and insulin resistance.

Abstract
OBJECTIVE To investigate insulin resistance imposed by liposuction, correlating its intensity with the extent of the operation. METHODS The sample consisted of 20 female patients without comorbidities, aged between 21 and 43 years, body mass index between 19 and 27 kg/m², undergoing liposuction alone or associated with breasts' prosthesis. We assessed insulin resistance at the beginning and end of the procedure by calculating the Homeostasis Model Assessment (HOMA-IR). The operative variables were length of liposuction, breast prosthesis time, body areas submitted to liposuction and total fat aspirated. RESULTS The liposuction time was 94-278 min (mean = 174 min), duration of breast prosthesis 20-140 min (mean = 65 min) and total fat aspirated 680-4280 g (mean = 1778 g). Statistical analysis was performed by considering a division line of 1500 g of aspirated fat and there was a significantly increased insulin resistance by HOMA index greater in the group > 1500 g (123% increase) than in the group d" 1500 g (an increase of 53 %) from the baseline data (p = 0.02). Other operative variables showed no significant correlation. CONCLUSION Insulin resistance shows significant increase in liposuction, and it is correlated to the volume of aspirated fat.

Abstract
High saturated and trans fatty acid intake, the typical dietary pattern of Western populations, favors a proinflammatory status that contributes to generating insulin resistance (IR). We examined whether the consumption of these fatty acids was associated with IR and inflammatory markers. In this cross-sectional study, 127 non-diabetic individuals were allocated to a group without IR and 56 to another with IR, defined as homeostasis model assessment-IR (HOMA-IR) >2.71. Diet was assessed using 24-h food recalls. Multiple linear regression was employed to test independent associations with HOMA-IR. The IR group presented worse anthropometric, biochemical and inflammatory profiles. Energy intake was correlated with abdominal circumference and inversely with adiponectin concentrations (r = -0.227, P = 0.002), while saturated fat intake correlated with inflammatory markers and trans fat with HOMA-IR (r = 0.160, P = 0.030). Abdominal circumference was associated with HOMA-IR (r = 0.430, P < 0.001). In multiple analysis, HOMA-IR remained associated with trans fat intake (β = 1.416, P = 0.039) and body mass index (β = 0.390, P < 0.001), and was also inversely associated with adiponectin (β = -1.637, P = 0.004). Inclusion of other nutrients (saturated fat and added sugar) or other inflammatory markers (IL-6 and CRP) into the models did not modify these associations. Our study supports that trans fat intake impairs insulin sensitivity. The hypothesis that its effect could depend on transcription factors, resulting in expression of proinflammatory genes, was not corroborated. We speculate that trans fat interferes predominantly with insulin signaling via intracellular kinases, which alter insulin receptor substrates.

Abstract
The relationship of body weight (BW) with white adipose tissue (WAT) mass and WAT gene expression pattern was investigated in mice submitted to physical training (PT). Adult male C57BL/6 mice were submitted to two 1.5-h daily swimming sessions (T, N = 18), 5 days/week for 4 weeks or maintained sedentary (S, N = 15). Citrate synthase activity increased significantly in the T group (P < 0.05). S mice had a substantial weight gain compared to T mice (4.06 ± 0.43 vs 0.38 ± 0.28 g, P < 0.01). WAT mass, adipocyte size, and the weights of gastrocnemius and soleus muscles, lung, kidney, and adrenal gland were not different. Liver and heart were larger and the spleen was smaller in T compared to S mice (P < 0.05). Food intake was higher in T than S mice (4.7 ± 0.2 vs 4.0 ± 0.3 g/animal, P < 0.05) but oxygen consumption at rest did not differ between groups. T animals showed higher serum leptin concentration compared to S animals (6.37 ± 0.5 vs 3.11 ± 0.12 ng/mL). WAT gene expression pattern obtained by transcription factor adipocyte determination and differentiation-dependent factor 1, fatty acid synthase, malic enzyme, hormone-sensitive lipase, adipocyte lipid binding protein, leptin, and adiponectin did not differ significantly between groups. Collectively, our results showed that PT prevents BW gain and maintains WAT mass due to an increase in food intake and unchanged resting metabolic rate. These responses are closely related to unchanged WAT gene expression patterns.

Abstract
OBJETIVO: Este estudo teve como objetivo analisar os efeitos imediatos do treinamento concorrente sobre a leptina e os níveis de cortisol em adultos jovens com sobrepeso. MÉTODOS: Este estudo utilizou uma metodologia quase-experimental. Foram 20 indivíduos voluntários de ambos os sexos, divididos em um grupo sobrepesado treinamento (GST n = 10) e um grupo sobrepesado controle (n = 10). A coleta de sangue foi realizada com os indivíduos em repouso após jejum de 12 horas. Os níveis de leptina e cortisol foram analisados por radioimunoensaio e ensaio por quimioluminescência chimiluminescence antes e imediatamente após o treinamento. ANOVA two way foi utilizada para análise estatística com nível de significância de p < 0,05. RESULTADOS: Na análise da leptina sérica, observou-se diferença significativa intergrupos (GST x GSC) nos momentos pré-intervenção (p = 0,02) e pós-intervenção (p = 0,01). Na análise intragrupos, não foram observadas alterações significativas. E na análise do cortisol sérico intergrupos (GST x GSC), foi observada uma diferença significativa nos momentos pré-intervenção (p = 0,01) e pós-intervenção (p = 0,01), porém, na análise intragrupos, não houve alterações significativas. CONCLUSÃO: Uma única sessão de treinamento concorrente não é suficiente para promover alterações agudas nos níveis de leptina e cortisol dos jovens adultos sobrepesados voluntários deste estudo.

Abstract
INTRODUÇÃO:A eletrolipólise é uma técnica destinada ao tratamento de acúmulo de tecido adiposo localizado em determinadas regiões. Sua aplicação ocorre por meio de pares de agulhas de acupuntura no tecido subcutâneo, ligadas a uma corrente de baixa frequência. Essa estimulação elétrica provoca diversas modificações fisiológicas no adipócito, dentre elas o incremento do fluxo sanguíneo local, aumento do metabolismo celular e queima de calorias. OBJETIVOS:Este estudo teve como objetivo avaliar o efeito da eletrolipólise na redução de gordura localizada na região infra-abdominal, em pacientes que praticam atividade física e nas sedentárias. MATERIAIS E MÉTODOS:As pacientes na faixa etária dos 18 aos 30 anos, sexo feminino, foram submetidas à avaliação em que foi medido o índice de massa corpórea (IMC) e a razão cintura/quadril (C/Q). Com uma fita métrica foi realizada a perimetria de cintura (abaixo da última costela), da crista ilíaca, 5 cm e 10 cm acima da crista ilíaca. Foram realizadas 20 sessões, sendo duas vezes por semana, com oito agulhas de acupuntura conectadas a um aparelho de estimulação transcutânea de corrente de baixa frequência (Tens). RESULTADOS: Foi observada a redução de medidas do tecido adiposo em ambos os grupos, havendo maior notoriedade no grupo das sedentárias. CONCLUSÃO:Apesar da significativa perda de tecido adiposo neste estudo, os resultados não foram expressivos pela desistência das voluntárias no decorrer do tratamento, sendo esse um ponto bastante dificultoso do trabalho, que deveria ter permanecido com as 26 pacientes.

Abstract
The objective of the present study was to investigate the relationship between inflammatory, metabolic, and anthropometrical parameters of elderly women with insulin resistance (IR) and without insulin resistance (WIR). One hundred and seventy-two elderly women aged 67.5 (± 5 years) were submitted to anthropometrical analysis, by dual energy X-ray absorptiometry, and biochemistry tests such as lipidogram, fasting blood glucose, glycosylated hemoglobin, insulin, C-reactive protein, Interleukin-6, tumor necrosis factor-alpha, and Interferon-gamma. Body mass index, waist circumference, waist-to-hip ratio, body fat mass, triglycerides, very low density lipoprotein, fasting glucose, and insulin were significantly higher, while lean body mass was lower ( p < 0.05), in elderly with IR as compared to WIR. There was no significant difference between groups in the inflammatory parameters. Elderly women with IR present increased anthropometrical and metabolic parameters that predispose them to several chronic nontransmissible diseases. Additional inflammatory parameters should be used in elderly women to define an optimal relationship with insulin resistance in clinical practice.

Abstract
Cancer cachexia is a multifaceted syndrome whose aetiology is extremely complex and is directly related to poor patient prognosis and survival. Changes in lipid metabolism in cancer cachexia result in marked reduction of total fat mass, increased lipolysis, total oxidation of fatty acids, hyperlipidaemia, hypertriglyceridaemia, and hypercholesterolaemia. These changes are believed to be induced by inflammatory mediators, such as tumour necrosis factor-α (TNF-α) and other factors. Attention has recently been drawn to the current theory that cachexia is a chronic inflammatory state, mainly caused by the host's reaction to the tumour. Changes in expression of numerous inflammatory mediators, notably in white adipose tissue (WAT), may trigger several changes in WAT homeostasis. The inhibition of adipocyte differentiation by PPARγ is paralleled by the appearance of smaller adipocytes, which may partially account for the inhibitory effect of PPARγ on inflammatory gene expression. Furthermore, inflammatory modulation and/or inhibition seems to be dependent on the IKK/NF-κB pathway, suggesting that a possible interaction between NF-κB and PPARγ is required to modulate WAT inflammation induced by cancer cachexia. In this article, current literature on the possible mechanisms of NF-κB and PPARγ regulation of WAT cells during cancer cachexia are discussed. This review aims to assess the role of a possible interaction between NF-κB and PPARγ in the setting of cancer cachexia as well as its significant role as a potential modulator of chronic inflammation that could be explored therapeutically.

Abstract
INTRODUÇÃO: A síndrome da desarmonia corporal (SDC) inclui a presença de fibroedema geloide (FEG), adiposidade localizada, aumento de gordura corporal total e flacidez muscular - frequentemente associados - e esses distúrbios estéticos representam uma ameaça à integridade emocional do indivíduo, sendo uma variedade de terapias propostas para o seu tratamento. OBJETIVOS: Avaliar os efeitos do ultrassom terapêutico (UST) e da eletrolipoforese no tratamento das alterações decorrentes do fibroedema geloide. MATERIAIS E MÉTODOS: Foram estudadas 22 voluntárias, com idade entre 17-35 anos, presença de FEG graus 1 e/ou 2 em glúteos, sedentárias e usando anticoncepcional. Previamente foram avaliadas as variáveis de perimetria, sensibilidade, dor, satisfação pessoal, adipometria, avaliação fotográfica e bioimpedância elétrica bipolar. Foram realizadas 10 sessões com UST em 11 das voluntárias e as demais 11 voluntarias receberam tratamento por eletrolipoforese. Todas as técnicas foram aplicadas na região glútea bilateralmente, três vezes por semana, e ao término do tratamento as variáveis foram reavaliadas. Na análise estatística foi aplicado o teste t de Student para verificar a significância entre os resultados obtidos em cada tratamento e entre os tratamentos. O nível de significância estabelecido foi de p < 0,05. RESULTADOS: Não houve diferença estatisticamente significante na perimetria, adipometria e bioimpedância após os tratamentos instituídos. Na avaliação fotográfica houve melhora no aspecto visual do FEG em 68,18% das participantes. A satisfação pessoal aumentou em ambos os grupos (UST p = 0,03* e eletrolipólise p = 0,04*). CONCLUSÃO: Os tratamentos apresentaram melhora no aspecto visual do FEG e na satisfação pessoal, porém não alteraram medidas perimétricas, de adipometria e da bioimpedância.

Abstract
OBJETIVO: Investigar a associação entre níveis elevados de adiponectina plasmática (AdipoQ) e baixo risco cardiometabólico (RCM) em obesas (MOb). SUJEITOS E MÉTODOS: Estudo caso-controle, pareado pela idade com 306 MOb, IMC > 30 kg/m², sendo 66 (21,6%) casos - todos não hipertensos, normolipídicos e não diabéticos - realizados em ambulatórios referência do Sistema Único de Saúde (SUS) para obesidade em Salvador. Dados secundários foram coleta-dos dos prontuários médicos, primários e complementares em laboratório de patologia clínica. Valores de AdipoQ > 10,00 µg/mL (> 3º quartil) foram considerados elevados. Foram realizadas análises: descritiva, bivariada e regressão logística condicional. RESULTADOS: Associação positiva, estatisticamente significante (ES), entre baixo RCM e AdipoQ > 10,00 µg/mL em MOb ativas fisicamente (OR= 5,1; IC95%: 1,8-14,3), não fumantes (OR= 3,6; IC95%: 1,6-8,4). CONCLUSÃO: Este estudo sugere que MOb ativas fisicamente, não fumantes e com níveis mais elevados de AdipoQ apresentam mais chances de baixo RCM. Torna-se importante reforçar, por meio de políticas públicas, o estímulo à adoção de comportamentos saudáveis.

Abstract
OBJECTIVE The purpose of this study was to describe the probable mechanism of the volume increase of laparoscopically harvested omentum flaps used to treat breast deformities. METHODS A histological analysis of omentum samples was performed to study the volume increase of laparoscopically harvested omentum flaps. Samples were harvested immediately after the transposition of the omentum from the abdominal cavity to the breast region and during the second surgical procedure for breast symmetrization of eight patients submitted to the transposition of the omentum flap. Changes in the morphometric measurements of the adipocytes (perimeter, diameter, and area), microvascular density (as measured by the CD31 endothelial marker), and immunohistochemical expression of VEGF were documented. RESULTS The increases in adipocyte size and microvascular density were statistically significant (P < 0.012). The expression levels of VEGF were lower in the second set of samples when compared to the first set, but the differences were not statistically significant (P < 0.093). CONCLUSION These results demonstrate an increase in cellular volume as measured by adipocyte perimeter, diameter, and area. Moreover, the increase in the number of vessels in the second set of samples suggests that neoangiogenesis was stimulated by the initial increase in VEGF expression levels observed in the first set of samples. The increase in VEGF expression in the flap may have been caused by adipocyte hypertrophy resulting from neoangiogenesis.

Abstract
This article aims to review clinical and diagnostic aspects of non-alcoholic fatty liver disease associated with obesity and its relation to metabolic syndrome in children and adolescents. An on-line search was carried out of original articles in the Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Eletronic Library Online (SciELO) databases, using the following key words: "hepatic steatosis", "nonalcoholic fatty liver diseases", "overweight", "obesity", "children", "adolescents", "ultrasound" and "metabolic syndrome" in English and Portuguese. Two hundred and seventy-five articles were initially selected, all published between 1993 and 2008. After reading this was narrowed down to 67. The literature consulted revealed no consensus regarding the need to screen for metabolic syndrome and non-alcoholic fatty liver disease, especially in obese children and adolescents and those who have excess fat in the abdominal region. An ultrasound examination of the liver is typically used for screening and, in the case of children who present alterations in aminotransferases in addition to fatty infiltration of the liver, a strict clinical follow-up and a liver biopsy are recommended if these symptoms do not disappear on treatment.

Abstract
A obesidade é uma doença complexa de etiologia multifacetada, com sua própria fisiopatologia, comorbidades e capacidades desabilitantes. Aceitar a obesidade como uma doença é fundamental para o seu tratamento. Atualmente, o tecido adiposo é um dos principais focos das pesquisas em obesidade, devido a uma revolução no entendimento da função biológica desse tecido desde a última década. Já está muito claro que o tecido adiposo branco secreta múltiplos peptídeos bioativos, denominados adipocinas (proteínas sintetizadas e secretadas pelo tecido adiposo). Dessa forma, o objetivo deste trabalho de revisão foi investigar a relação entre obesidade e adipocinas inflamatórias, buscando discutir o papel do exercício físico no tratamento dessa patologia. Os resultados demonstram que uma das mais importantes descobertas das pesquisas recentes em obesidade é o conceito de que ela é caracterizada por uma inflamação crônica. Dentre todas as adipocinas, sem dúvida, a IL-6, o TNF-α, a leptina (pró-inflamatórias) e a adiponectina (anti-inflamatória) vêm recebendo atenção especial da literatura especializada. O aumento da concentração dessas adipocinas promove grande impacto em diversas funções corporais que estão fortemente correlacionadas com doenças cardiovasculares. Uma vez que a obesidade é considerada uma doença inflamatória e o exercício físico modula de forma direta tais processos, é essencial que tenhamos como um dos objetivos principais de nossos programas de exercícios físicos a melhora da resposta inflamatória de obesos.

Abstract
OBJECTIVE Obesity is an increasingly prevalent nutritional disorder throughout the world. In particular, abdominal obesity is associated with cardiovascular and metabolic risk. The present study aimed to evaluate the effects of skin colour and life-course socio-economic indicators on waist circumference (WC), hip circumference (HC) and waist:hip ratio (WHR) in young adults. DESIGN Population-based birth cohort study. Individuals born in 1982 in Pelotas (southern Brazil) were visited on a number of occasions from birth to age 23-24 years. A sample of the cohort was sought in 2006 and 972 individuals were located. The analysis was restricted to individuals with complete data available (442 males, 414 females). RESULTS In men, family income at birth and in 2004-5 were positively associated with WC and HC, but not with WHR. Regardless of current income, men born to wealthier families had larger WC and HC as adults. Skin colour was not associated with any of the outcomes. In women, early poverty was associated with smaller HC, and current poverty with larger WC. Poverty at any age thus led to higher WHR. Black women had larger WC and HC than white women, but there were no differences in WHR. All the associations were partially mediated by education and behavioural variables. CONCLUSIONS The effects of early socio-economic position on WC and HC persist even after adjustment for adult socio-economic position, highlighting the importance of interventions during the first years of life.

Abstract
OBJETIVO: Investigar as alterações dos marcadores inflamatórios em obesos com glicemia de jejum alterada. MÉTODOS: Foram avaliados 125 indivíduos adultos tendo sido pesquisados: Índice de Massa Corporal, circunferência da cintura, glicemia de jejum, proteína C reativa ultra-sensível, ácido úrico e homocisteína. Os grupos apresentando glicemia de jejum normal (grupo 1) e glicemia de jejum alterada (grupo 2) foram comparados entre si e em associação aos subgrupos de obesos, sobrepesos e eutróficos. RESULTADOS: O grupo 2 apresentou maiores valores de circunferência da cintura (p<0,05), principalmente quando associados ao excesso de peso. Adicionalmente, o grupo 2 mostrou valores de proteína C reativa e ácido úrico superiores, sendo os dos obesos maiores que os com sobrepeso e os eutróficos, enquanto a homocisteína foi semelhante entre obesos, com sobrepeso e eutróficos. O Índice de Massa Corporal correlacionou-se positivamente com ambos ácido úrico (r=0,39, p<0,01) e proteína C reativa (r=0,37; p<0,01). A circunferência da cintura apresentou correlação apenas com o ácido úrico (r=0,53, p<0,01). Porém, a correlação entre Índice de Massa Corporal e proteína C reativa foi significante no grupo 2 (r=0,66, p<0,01), mas não no grupo 1 (r=0,25, p>0,05). O mesmo resultado foi encontrado em relação à circunferência da cintura e à proteína C reativa, que se correlacionaram significantemente somente na presença de glicemia de jejum alterada (r=0,40, p<0,05). Na regressão logística, a circunferência da cintura foi a variável explicativa (11%, p<0,01) da alteração da glicemia de jejum. CONCLUSÃO: Os estados pró-oxidativo e pró-inflamatório estiveram significantemente associados à glicemia de jejum alterada na presença de adiposidade corporal.

Abstract
O chá é uma bebida amplamente utilizada, perdendo apenas para a água como a bebida mais consumida no mundo. O chá verde é rico em polifenóis, principalmente catequinas. Entre uma variedade de efeitos benéficos à saúde atribuídos ao consumo do chá verde, grande atenção tem sido focalizada no seu efeito na redução da gordura corporal. Este estudo tem como objetivo apresentar uma descrição dos estudos com o chá verde e/ou seus compostos bioativos relacionados à biologia celular, estudos experimentais e epidemiológicos associados ao metabolismo lipídico e à redução da gordura corporal. Galato de epigalocatequina é o principal composto bioativo presente no chá verde e seus efeitos anti-obesidade estão sendo investigados. Tais efeitos estão associados a diversos mecanismos bioquímicos e fisiológicos, dentre eles podem-se destacar a estimulação do metabolismo lipídico pela combinação da ingestão de catequinas e a prática de exercícios físicos regulares. Apesar do efeito promissor do chá verde e seus compostos bioativos no tratamento da obesidade, estudos clínicos controlados devem ser conduzidos. Finalmente, um plano alimentar adequado associado à prática regular de atividade física constitui a principal ferramenta para a prevenção da obesidade e de suas comorbidades.

Abstract
Atherosclerosis is a complex and multifactorial disease, which determines clinical events that cause significant morbidity-mortality, represented by acute myocardial infarction, angina and sudden death. It is associated with lipid disturbances, platelet activation, thrombosis, endothelial dysfunction, inflammation, oxidative stress, altered matrix metabolism, among other disturbances. All these abnormalities are usual and more pronounced in diabetic patients, as well as in the post-prandial state. Among the coronary artery disease risk factors that are not usually employed in clinical practice in the whole population, postprandial hyperlipemia plays a major role, being a possible early marker of metabolic abnormalities and vascular dysfunction not yet seen in the fasting state. Recent results showed that post-oral lipid overload changes are negatively associated with endothelial dysfunction, and vascular reactivity abnormalities are strongly related to atherosclerosis progression and cardiovascular events. These abnormalities could disclose a lipid intolerance state that can be detected in apparently healthy subjects even before fasting abnormalities are seen. This review will deal with the pathophysiology changes involved in post-prandial hyperlipemia and its relationship with atherogenesis, with particular emphasis to diabetes mellitus.
