Nutrients 2022; 14:nu14030479. [PMID: 35276837 PMCID: PMC8839826 DOI: 10.3390/nu14030479] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/14/2022] [Accepted: 01/20/2022] [Indexed: 02/07/2023] Open
Abstract
Background: Changes in adipokine secretion may be involved in the anti-epileptic effect of a ketogenic diet (KD) in drug-resistant epilepsy (DRE). Objectives: The assessment of the influence of KD on serum adiponectin, omentin-1, and vaspin in children with DRE. Methods: Anthropometric measurements (weight, height, BMI, and waist-to-hip circumference ratio) were performed in 72 children aged 3–9 years, divided into 3 groups: 24 children with DRE treated with KD, 26—treated with valproic acid (VPA), and a control group of 22 children. Biochemical tests included fasting glucose, insulin, beta-hydroxybutyric acid, lipid profile, aminotransferases activities, and blood gasometry. Serum levels of adiponectin, omentin-1 and vaspin were assayed using commercially available ELISA tests. Results: Serum levels of adiponectin and omentin-1 in the KD group were significantly higher and vaspin—lower in comparison to patients receiving VPA and the control group. In all examined children, serum adiponectin and omentin-1 correlated negatively with WHR and serum triglycerides, insulin, fasting glucose, and HOMA-IR. Vaspin levels correlated negatively with serum triglycerides and positively with body weight, BMI, fasting glucose, insulin, and HOMA-IR. Conclusion: One of the potential mechanisms of KD in children with drug-resistant epilepsy may be a modulation of metabolically beneficial and anti-inflammatory adipokine levels.

Abstract
Background This research aimed to investigate the association between dietary patterns with severity of coronary artery stenosis, serum leptin-to-adiponectin ratio, and some related risk factors in patients with coronary artery disease referred for coronary angiography. Methods This cross-sectional study was carried out on 191 men patients with known coronary disease aged 40-70 years whom were admitted to angiography ward of Ahvaz teaching hospital, Ahvaz, Iran. Dietary patterns were investigated using 161-item semi-quantitative food frequency questionnaire. Anthropometric indices; blood pressure; serum levels of adiponectin and leptin, blood levels of glucose, total cholesterol, HDL-C, LDL-C, and triglycerides were measured. Patients were categorized based on the severity of coronary artery disease [number of vessel involved-single (VD1), double (VD2), triple (VD3)]. Results Three major dietary patterns were recognized using a factor analysis approach: western, healthy, and traditional patterns. Linear regression analysis demonstrated that there was a negative association between healthy dietary pattern with LDL-C, total cholesterol, and triglycerides. This dietary pattern was positively related to HDL-C. Both traditional and western dietary patterns were related to fasting blood glucose level and lipid profile. General obesity was positively associated with traditional and western dietary patterns. There was a positive relationship between central obesity with traditional and western dietary patterns, but a negative association was reported between the healthy dietary pattern and central obesity. Traditional and western dietary patterns demonstrated a significant positive relationship with serum leptin levels and ratio of L/A, and an inverse relationship with adiponectin. Healthy dietary pattern had a significant negative association with serum leptin levels and ratio of L/A. Healthy dietary pattern was negatively related to the severity of vessel stenosis. Patients in the third quartile of healthy dietary pattern were less likely to have vessel stenosis (OR = 43%, 95% CI: 0.07-0.87). Conclusions The findings show that adherence to a healthy dietary pattern was negatively associated with coronary artery stenosis and its related risk factors. However, adherence to western and traditional dietary patterns was positively related to coronary artery disease risk factors.

Abstract
PURPOSE Inflammation and oxidative stress are implicated in obstructive sleep apnea (OSA) pathophysiology. We aimed at exploring whether the combination of a weight-loss Mediterranean diet/lifestyle intervention with OSA standard care, i.e., continuous positive airway pressure (CPAP) prescription, can lead to greater improvements in inflammation and oxidative stress, compared to standard care alone. METHODS This was a randomized controlled clinical trial in 187 adult, overweight patients with moderate-to-severe OSA. Participants were randomized to a standard care (SCG, n = 65), a Mediterranean diet (MDG, n = 62) or a Mediterranean lifestyle group (MLG, n = 60). All groups received OSA standard care. Intervention arms participated in a 6-month behavioral weight-loss intervention based on the Mediterranean diet, while the MLG also received counselling on physical activity and sleep habits. RESULTS Seven patients were excluded and 53/180 were lost to follow-up. In intention to treat analysis (n = 180), the SCG did not exhibit changes in any of the markers assessed. Post-intervention age-, sex-, baseline- and CPAP use-adjusted plasma high sensitivity C-reactive protein levels (mg/L) were lower in the MDG and the MLG compared to the SCG (mean difference - 1.33, P = 0.039 and - 1.68, P = 0.007, respectively). The MLG also exhibited lower urinary 8-iso prostaglandin F2a levels (ng/mg creatinine) compared to the SCG and the MDG (mean difference - 1.10, P < 0.0001 and - 0.80, P = 0.001, respectively). Adiponectin and oxidized guanine levels were not altered in any of the study groups. Results were similar in per protocol analysis (n = 127). CONCLUSION A weight-loss Mediterranean diet/lifestyle intervention on top of CPAP has anti-inflammatory and antioxidant benefits in OSA. REGISTRATION The trial was prospectively registered at ClinicalTrials.gov (NCT02515357) on August 4, 2015.

Abstract
The relationship between serum vaspin levels and metabolic or coronary artery disease is currently of interest for researchers. Although adipokine concentrations have been shown to be increased significantly in atherosclerotic lesions, the role adipokines in the atherosclerotic process
remains to be elucidated. Vaspin is a new biological marker associated with obesity and impaired insulin sensitivity. Plasma vaspin concentration has been shown to correlate with the severity of coronary artery disease. Vascular inflammation triggered by vaspin inhibits atherogenesis by suppressing
macrophage foam cell formation and vascular smooth muscle cell migration and proliferation. Vaspin also contributes to plaque stabilization by increasing collagen content and reducing the intraplaque macrophage to vascular smooth muscle cell ratio. The therapeutic goal concerning vaspin is
to fight atherosclerosis and related diseases, as well as to maintain vascular health.

Abstract
BACKGROUND Cartonectin is a potent anti-inflammatory adipokine that might be implicated in metabolism and energy storage. Our objective was to evaluate the influence of weight reduction following laparoscopic sleeve gastrectomy (LSG) on serum cartonectin and vaspin levels. SUBJECTS AND METHODS Thirty-two individuals (29 female and 3 male) with morbid obesity underwent LSG. Anthropometric indices, lipid profile, fasting serum concentrations of glucose, insulin, vaspin, and cartonectin were measured prior and 3 months after LSG. Insulin sensitivity was determined using the homeostasis model assessment of insulin resistance (HOMA-IR). RESULTS Following LSG, circulating cartonectin level increased significantly while serum vaspin was significantly decreased. The percentage change of serum cartonectin level correlated negatively with the percentage changes in body mass index, waist circumference, and waist-hip ratio and positively with percentage changes in LDL-C, triglycerides, and HOMA-IR after adjustment for age and sex. Moreover, the changes in vaspin concentration positively correlated with the changes in insulin level and HOMA-IR after adjustment for age and sex. In a multiple stepwise linear regression model, the changes in waist circumference explained 13% variability of changes in cartonectin level while the changes in HOMA-IR and LDL-C were responsible for 31% of the variability in changes of vaspin level. CONCLUSION LSG-induced weight loss rapidly increases serum cartonectin level and decreases the serum vaspin level in morbidly obese subjects. The changes in cartonictin level seem to be influenced by the changes of waist circumference while the changes of HOMA-IR and LDL-C might be determinant factors of the changes in vaspin level.

ACTA ACUST UNITED AC 2019; 55:medicina55030076. [PMID: 30909620 PMCID: PMC6473861 DOI: 10.3390/medicina55030076] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Revised: 03/14/2019] [Accepted: 03/20/2019] [Indexed: 12/30/2022]
Abstract
Background and objectives: Data concerning vaspin in obstetric aspects are limited and conflicting. The aim of the study was to evaluate vaspin concentrations in the serum and urine of women with excessive gestational weight gain (EGWG) in the early post-partum period (i.e., 48 h after delivery), when placental function no longer influences the results. Materials and Methods: The study subjects were divided into two groups of 28 healthy controls and 38 mothers with EGWG. Maternal body composition and hydration status were evaluated by the bioelectrical impedance analysis (BIA) method. Concentrations of vaspin, fatty acid-binding protein 4 (FABP4), leptin, and ghrelin were determined via enzyme-linked immunosorbent assay (ELISA). Results: Serum vaspin levels were lower in the EGWG group, whereas no significant differences were noted between the groups, with regard to the urine vaspin concentrations. In both studied groups, the serum vaspin concentrations correlated positively with the urine FABP4 levels and negatively with gestational weight gain, body mass index gain in the period from pre-pregnancy to 48 h after delivery (ΔBMI), and fat tissue index (FTI). In the multiple linear regression models, the serum vaspin concentrations were positively dependent on the serum FABP4 levels, as well as negatively dependent on triglycerides, FTI, and ΔBMI. Conclusions: Our study revealed that the EGWG mothers were characterized by significantly lower serum vaspin concentrations in the early post-partum period compared with the subjects that had appropriate gestational weight gain. Our observation supports previous hypotheses that vaspin might be used as a marker of lipid metabolism in pregnancy and maternal adipose tissue. Considering the fact that FABP4 is widely referred to as a pro-inflammatory adipokine, further research on the protective role of vaspin seems crucial, especially in the context of its relationship to FABP4.

Abstract
Gestational diabetes mellitus (GDM) is considered to be one of the most frequent medical complication observed among pregnant women. The role of adipokines in the pathogenesis of GDM remains strictly unknown. Different adipokines have been studied throughout gestation, and they have been proposed as biomarkers of GDM and other pregnancy-related complications; however, there is no biomarker reported for GDM screening at present. The aim of this study was to evaluate serum nesfatin-1 and vaspin levels in GDM and non-GDM women, to characterize the correlation between these adipokines, and to assess the potential role of circulating adipokines in the prediction of risk of gestational diabetes mellitus. Serum concentrations of nesfatin-1 and vaspin were measured in 153 women with GDM, and in 84 patients with uncomplicated pregnancy by enzyme-linked immunosorbent assay (ELISA) kits, according to the manufacturer's instructions. Circulating levels of nesfatin-1 and vaspin were significantly lower in the GDM group than in the control group. Nesfatin-1 levels were negatively correlated with vaspin levels. The results of this study point out the possible role of nesfatin-1 and vaspin as potential novel biomarkers for the prediction and early diagnosis of GDM. Further studies are necessary to evaluate the influence of nesfatin-1 and vaspin on glucose metabolism in the early stages of GDM.

Abstract
Mediterranean-style diets provide cardiovascular benefits and increase insulin sensitivity. There is little evidence that adherence to Mediterranean diet may influence the levels of the inflammatory milieu in type 2 diabetes. The aim of this study was to assess whether Mediterranean diet influences both C-reactive protein (CRP) and adiponectin in newly diagnosed type 2 diabetes, and whether adherence to Mediterranean diet affects their circulating levels. In a two-arm, single-center trial, 215 men and women with newly diagnosed type 2 diabetes were randomized to a Mediterranean diet (n = 108, 54 males and 54 females) or a low-fat diet (n = 107, 52 males and 55 females), with a total follow-up of 8.1 years. At baseline visit and at 1 year, body weight, HOMA index, CRP, and adiponectin and its fractions were assessed. Adherence to the diets was assessed by calculating the Mediterranean-diet score. At 1 year, CPR fell by 37 % and adiponectin rose by 43 % in the Mediterranean diet group, while remaining unchanged in the low-fat diet group. The pattern of adiponectin fractions (high and non-high molecular weight) showed a response similar to that of total adiponectin. Diabetic patients with the highest scores (6-9 points) of adherence to Mediterranean diet had lower circulating CRP level and higher circulating total adiponectin levels than the diabetic patients who scored <3 points on the scale (P = 0.001). The results of this randomized controlled trial demonstrate that Mediterranean diet cools down the inflammatory milieu of type 2 diabetes.

Abstract
BACKGROUND Vaspin (VASP) is a protein detected in pre- and mature adipocytes, the production and secretion of which may be conditioned by nutrition status. VASP may also play a role in the regulation of food intake. Since to date, there are no available studies on serum vaspin concentrations in patients with anorexia nervosa (AN), the aim of our study is to assess serum vaspin concentrations in girls with AN in comparison to healthy subjects and determine its relationship with body weight, body masss index (BMI) and insulin. METHODS In this cross-sectional study vaspin serum concentrations were evaluated using a commercially available ELISA kit in 47 Polish girls hospitalized due to restrictive AN and 39 healthy controls (H). RESULTS The mean serum concentration of VASP in girls with AN was significantly higher than in the H group. These differences were also noted after adjustment for body masss index-standard deviation score (BMI-SDS), the homeostatic model assessment-insulin resistance (HOMA-IR) index and insulin levels. There were no statistically significant correlations between the serum concentrations of VASP and body mass, BMI, BMI-SDS, insulin and HOMA-IR in the AN or healthy group. CONCLUSIONS Serum vaspin levels in lean subjects are regulated in different mechanisms than previously reported in obesity. It should be established if elevated serum vaspin levels in girls with AN may contribute to low food intake in these patients.

Abstract
The marked disparity in life expectancy between men and women suggests men are a vulnerable group requiring targeted health promotion programs. As such, there is an increasing need for health promotion strategies that effectively engage men with their health and/or illness management. Programs that promote physical activity could significantly improve the health of men. Although George et al. (Sports Med 42(3):281, 30) reviewed physical activity programs involving adult males published between 1990 and 2010, developments in men's health have prompted the emergence of new sex- and gender-specific approaches targeting men. The purpose of this review was to: (1) extend and update the review undertaken by George et al. (Sports Med 42(3):281, 30) concerning the effectiveness of physical activity programs in males, and (2) evaluate the integration of gender-specific influences in the content, design, and delivery of men's health promotion programs. A search of MEDLINE, CINAHL, ScienceDirect, Web of Science, PsycINFO, the Cochrane Library, and the SPORTDiscus databases for articles published between January 2010 and August 2014 was conducted. In total, 35 studies, involving evaluations of 31 programs, were identified. Findings revealed that a variety of techniques and modes of delivery could effectively promote physical activity among men. Though the majority of programs were offered exclusively to men, 12 programs explicitly integrated gender-related influences in male-specific programs in ways that recognized men's interests and preferences. Innovations in male-only programs that focus on masculine ideals and gender influences to engage men in increasing their physical activity hold potential for informing strategies to promote other areas of men's health.

The role of vaspin in the development of metabolic and glucose tolerance disorders and atherosclerosis. BIOMED RESEARCH INTERNATIONAL 2015; 2015:823481. [PMID: 25945347 PMCID: PMC4402467 DOI: 10.1155/2015/823481] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/04/2015] [Accepted: 03/30/2015] [Indexed: 12/03/2022]
Abstract
In recent years, most research efforts have been focused on studying insulin-sensitizing adipokines. One of the most recently discovered adipokines is vaspin, a visceral adipose tissue-derived serine protease inhibitor. Vaspin levels have been found significantly increased in mice with obesity and insulin resistance. It has been assumed that vaspin serves as an insulin sensitizer with anti-inflammatory effects and might act as a compensatory mechanism in response to decreased insulin sensitivity. Most studies in humans have shown a positive correlation between vaspin gene expression and serum levels, and metabolic syndrome parameters. Vaspin gene expression is influenced by age and gender, and the administration of insulin sensitizers enhances it in mice, whereas the use of metformin decreases serum vaspin levels in humans, probably due to different regulatory mechanisms. Presumably vaspin plays local and endocrine role in the development of initial and advanced atherosclerosis in obese subjects and might be used as a predictor of coronary and cerebrovascular disease. It is believed that vaspin could be regarded as a new link between obesity and related metabolic disorders, including glucose intolerance. The entire understanding of vaspin intimate mechanism of action might enable the development of novel etiology-based treatment strategies, targeting metabolic and glucose tolerance disorders.

Abstract
OBJECTIVE Dietary patterns reflect diet and nutritional habits of individuals in a society. Various dietary patterns could influence leptin and adiponectin secretion from adipose tissue. These hormones are associated with metabolic diseases. It is suggested that the leptin-to-adiponectin (L/A) ratio might be a more useful diagnostic marker in predicting chronic diseases than leptin and adiponectin separately. The aim of this study was to investigate the association between various dietary patterns and L/A ratio in Iranian adults. METHODS This cross-sectional study was conducted on 150 apparently healthy subjects aged 25-50 years in Tabriz, Iran. Dietary patterns were determined using 132-item semiquantitative food frequency questionnaire on a 5-point scale. Weight, height, waist circumference (WC), as well as fasting serum leptin and adiponectin levels were measured to assess the association between dietary patterns and L/A ratio. RESULTS Four major dietary patterns were identified using a factor analysis approach: Western, healthy, mixed, and traditional dietary patterns. Linear regression analysis showed that a Western dietary pattern was negatively associated with serum adiponectin concentration, even after adjusting for the confounders (r = -0.19, p = 0.02). No statistically significant associations were found between any dietary pattern and leptin (r = -0.14, p = 0.06) or L/A ratio (r = -0.10, p = 0.09). CONCLUSION Our findings indicate an inverse association between a Western dietary pattern and serum adiponectin levels but not for serum leptin or L/A ratio.

Abstract
Purpose Vaspin (visceral-adipose-tissue-derived-serine-protease-inhibitor) is a recently identified adipokine with putative insulin-sensitizing properties. Plasma vaspin responses to surgery-induced weight loss are sparse and contradictory. Design and Participants We evaluated changes in vaspin levels and relationship to post-operative outcomes in men (n = 22) and women (n = 55) undergoing biliopancreatic-diversion/duodenal-switch bariatric surgery. Body composition and plasma parameters were measured at baseline, acutely (1 and 5 days) and medium-term (6 and 12 months) post-surgery. Results Fasting preoperative vaspin concentrations were comparable in men vs women. The distribution was biphasic (both men and women) with a nadir of 2.5 ng/ml. Subjects were divided into high (≥2.5 ng/mL, HI-group) and low (<2.5 ng/mL, LO-group) vaspin level. Both groups had comparable sex distribution, age and BMI, but the HI-vaspin group had lower insulin, HOMA, and triglyceride and higher HDL-cholesterol, acylation stimulating protein (ASP) and IL-6 levels (all p<0.05). Post-operatively, both groups decreased BMI comparably over 12 months; the HI-vaspin group maintained high vaspin levels, while the LO-vaspin group gradually increased their levels with weight loss over 12 months. The HI-vaspin group maintained a better glucose, insulin, HOMA, fructosamine, HDL-cholesterol, and triglyceride profile throughout. The HI-vaspin group also had higher gamma-glutamyltransferase and ASP profiles. Finally, baseline vaspin level inversely correlated significantly with baseline and 12-month insulin, HOMA, triglyceride and positively correlated with HDL and ASP. Twelve-month vaspin also correlated similarly, including an inverse correlation with BMI. Conclusion Globally, this study supports the concept of vaspin as a beneficial adipokine in obesity, which may potentially lead to possible therapeutic targets.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and can progress to cirrhosis, liver failure, and hepatocellular carcinoma. In the last two decades, the prevalence of NAFLD has been growing in most developed countries, mainly as a consequence of its close association with obesity and diabetes mellitus. The exact pathogenesis of NAFLD and especially the mechanisms leading to disease progression have not been completely understood. Adipocytes produce and secrete several bioactive substances known as adipocytokines which are implicated in the pathogenesis of the disease. Among them, adiponectin is an insulin-sensitizing adipocytokine possessing multiple beneficial effects on obesity-related medical complication. This review focuses on the role of adiponectin in NAFLD pathogenesis and its potential use as a diagnostic tool but also as therapeutic target for NAFLD management.

Abstract
BACKGROUND Visceral adipose tissue-derived serine protease inhibitor (vaspin) is a recently identified adipokine. Studies suggest it is involved in many diseases such as obesity, diabetes and coronary artery disease (CAD). This study is to investigate the association of single nucleotide polymorphisms (SNPs) in vaspin with CAD and its potential mechanisms. METHODS A total of 1570 consecutive patients undergoing coronary angiography were enrolled and the genotypes were determined by TaqMan allelic discrimination. Serum vaspin concentrations and mRNA expression levels were determined by ELISA and RT-PCR, respectively. Reporter gene assay was performed to investigate the effect of polymorphism on vaspin promoter function. RESULTS After multivariate analysis, allele A of rs2236242 was found as an independent determinant of CAD (OR=1.32, p=0.004). Rs35262691 in vaspin promoter was associated with serum vaspin concentration and mRNA expression in peripheral blood mononuclear cells (PBMC) though no association had been found with CAD. Reporter gene assay further confirmed that CC genotype of rs35262691 had 2.1±0.4-fold higher activities than TT genotype in facilitating gene expression. CONCLUSIONS Our results show that the variants of vaspin gene are associated with serum vaspin levels and risk for CAD in Chinese population.

Abstract
OBJECTIVE To evaluate the effectiveness of two lifestyle, interventional approaches on metabolic abnormalities and eating habits of patients with metabolic syndrome. MATERIALS/METHODS This is a randomized controlled trial, involving a 6-month lifestyle intervention. Eighty-eight metabolic syndrome patients were randomized to one of the three groups: (i) "Increase - Decrease" group, (ii) "Increase" group, and (iii) "Minimum intervention" group. All patients received dietary and physical activity advice at baseline; patients in the first two groups also participated in individual counseling sessions. In the "Increase - Decrease" group, all recommended dietary and physical activity goals were targeted, whereas in the "Increase" group, only goals proposing an increase in dietary intake or physical activity were included. Patients received nutrition counseling through seven, one-to-one sessions, conducted every two weeks for the first 2 months, every month for the following 4 months. All participants underwent a full medical and nutritional assessment at baseline and at the end of the intervention. RESULTS At 6 months, BMI and waist circumference were improved in the "Increase" and the "Increase - Decrease" groups, compared to the "Minimum Intervention" group. Additionally, "Increase - Decrease" group reduced blood systolic (p=0.017), diastolic pressure (p=0.005) and glucose concentrations (p=0.015). Forty eight percent, 32%, and 19% of the patients in the "Increase - Decrease", "Increase" and "Minimum Intervention" groups, respectively, ceased to fulfill the criteria for the metabolic syndrome (p=0.031). CONCLUSIONS Promoting only the increase of the intake of healthy foods did not result in better outcome values compared to a conventional all-food approach.

Abstract
Objective: To examine whether there is an association between the serum concentration of vaspin and the presence of carotid plaque in early stage type 2 diabetes mellitus (T2DM). Methods: Patients ( n = 61) with T2DM within 3 years of diagnosis were divided into those with and those without carotid plaque. Fasting serum vaspin levels, measured by enzymelinked immunosorbent assay, and blood pressure were compared between these two groups and also with an age-matched, apparently healthy control group ( n = 26). Results: Fasting serum vaspin concentrations were significantly higher in patients with T2DM without carotid plaque than in controls, but significantly lower in T2DM patients with carotid plaque than inthose without. Multivariate logistic regression analysis showed a significant positive association between the presence of carotid plaque and systolic blood pressure and a significant inverse association between the presence of carotid plaque and fasting serum vaspin concentration. Conclusion: A significant inverse association was found, in patients with T2DM within 3 years of diagnosis, between serum vaspin concentration and the presence of carotid plaque.

Abstract
Stress, that is, the state of threatened or perceived as threatened homeostasis, is associated with activation of the stress system, mainly comprised by the hypothalamic-pituitary-adrenal axis and the arousal/sympathetic nervous systems. The stress system normally functions in a circadian manner and interacts with other systems to regulate a variety of behavioral, endocrine, metabolic, immune, and cardiovascular functions. However, the experience of acute intense physical or emotional stress, as well as of chronic stress, may lead to the development of or may exacerbate several psychologic and somatic conditions, including anxiety disorders, depression, obesity, and the metabolic syndrome. In chronically stressed individuals, both behavioral and neuroendocrine mechanisms promote obesity and metabolic abnormalities: unhealthy lifestyles in conjunction with dysregulation of the stress system and increased secretion of cortisol, catecholamines, and interleukin-6, with concurrently elevated insulin concentrations, lead to development of central obesity, insulin resistance, and the metabolic syndrome. Fetal life, childhood, and adolescence are particularly vulnerable periods of life to the effects of intense acute or chronic stress. Similarly, these life stages are crucial for the later development of behavioral, metabolic, and immune abnormalities. Developing brain structures and functions related to stress regulation, such as the amygdala, the hippocampus, and the mesocorticolimbic system, are more vulnerable to the effects of stress compared with mature structures in adults. Moreover, chronic alterations in cortisol secretion in children may affect the timing of puberty, final stature, and body composition, as well as cause early-onset obesity, metabolic syndrome, and type 2 diabetes mellitus. The understanding of stress mechanisms leading to metabolic abnormalities in early life may lead to more effective prevention and intervention strategies of obesity-related health problems.

Abstract
Vaspin (visceral adipose tissue-derived serpin; serpinA12) was originally identified as an adipokine, which is predominantly secreted from visceral adipose tissue in Otsuka Long-Evans Tokushima fatty (OLETF), an animal model of obesity and type 2 diabetes. Consistent with that higher vaspin serum concentrations and increased vaspin mRNA expression in human adipose tissue were found to be associated with obesity, insulin resistance, and type 2 diabetes in humans. However, the mechanisms how vaspin secretion may be linked to deterioration of glucose metabolism and insulin sensitivity are not entirely understood. Vaspin serum concentrations show a food intake-related diurnal variation. Vaspin is also expressed in the skin, hypothalamus, pancreatic islets, and stomach. Administration of vaspin to obese mice improves glucose tolerance, insulin sensitivity, and reduces food intake. Until now molecular target(s) of vaspin and its mode of action are unknown. Thus, identification of the proteases, which are inhibited by vaspin may lead to the development of novel strategies in the treatment of obesity, diabetes and insulin resistance. This review discusses the clinical relevance of vaspin in the pathophysiology of obesity and type 2 diabetes.

Abstract
The aims of the study were to determine the prevalence of metabolic syndrome (MS) components and examine associations with adipokine concentrations in a healthy pediatric cohort. A cross-sectional study of 1138 children (53% girls; mean age of all participants, 11.2 ± 0.7 years) was performed. Anthropometric and medical information was obtained; and a fasting blood sample was used to measure glucose, insulin, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, leptin, and adiponectin serum concentrations. Insulin resistance was assessed by the insulin resistance homeostasis model assessment. Body weight status (normal, overweight, and obese) was determined according to the International Obesity Task Force. Estimation of the MS was based on the International Diabetes Federation definition. The prevalence of the MS was 0.7% of children, all of whom were obese. Frequency of abdominal obesity, high fasting glucose, elevated triglycerides, low high-density-lipoprotein cholesterol, and elevated blood pressure was 4.8%, 4.7%, 0, 12.3%, and 33%, respectively. Body mass index (BMI) and z-BMI score increased significantly as the number of cardiometabolic risk factors increased. Regression analysis revealed that adiponectin (β = -0.501, P = .003) and leptin (β = 0.184, P < .0001) independently predicted the number of MS features. This finding was no longer significant after adjustment for BMI. In the present study, we provide the first estimate of the prevalence of the MS among healthy periadolescents in Greece using the International Diabetes Federation criteria. The MS prevalence was low, with elevated blood pressure being the most dominant feature. Finally, associations with adipokines are mediated by BMI.

Abstract
Shift work has been associated with a higher propensity for developing nutritional problems and obesity. However, the possible changes in leptin and ghrelin (2 hormones that contribute importantly to the central regulation of food intake) concentrations in this population are poorly described. The objective of the study was to evaluate the daily concentrations of leptin, nonacylated ghrelin, and acylated ghrelin and the appetite ratings in men working different shift schedules. Daily concentrations of nonacylated ghrelin, acylated ghrelin, and leptin and appetite were measured in 3 groups of subjects: workers on fixed night shifts (n = 9), fixed early morning shifts (n = 6), and fixed day shifts (n = 7). Appetite was evaluated by a validated questionnaire. Blood samples were collected every 4 hours over the course of 24 hours for a total of 6 samples. When comparing the 3 groups, leptin concentrations at 8:00 am and 4:00 pm for those workers on the day shift were significantly lower than for those on the early morning shift; and concentrations at noon for those workers on the day shift were significantly lower than for those on the night shift. Nonacylated and acylated ghrelin concentrations were significantly lower for those workers on the early morning shift than for those on the day shift. In general, appetite was the lowest in those working the early morning shift. Shift workers on the early morning shift have lower appetites and concentrations of leptin and nonacylated and acylated ghrelin than the workers on other shifts. Further studies are required to better understand the detailed needs of these individuals.
