Abstract
BACKGROUND The presence of hepatitis B infection (HBI) and metabolic syndrome (MS) at the same time constitutes a high risk for liver cirrhosis and potentially hepatocellular carcinoma. AIM In this study we aim to explore the relationship between MS and HBI. METHODS We used data from the cross-sectional HepaMeta study conducted in 2011 in Slovakia. Patients were tested for presence of MS, while lipid levels (total cholesterol, HDL, LDL, TG, apolipoprotein B100 and HBI (HBsAg and antiHBcIgG)) were also monitored. Viral load was measured in HBsAg positive patients. RESULTS Altogether 855 patients were screened, MS was diagnosed in 25.1% of patients and 7.9% of patients presented with HBI. AntiHBcIgG antibodies were present in 34.6% patients. HBI patients had lower levels of total and LDL cholesterol along with a decreased apolipoprotein B100 (4.54 ± 0.84 vs. 5.0 ± 0.99 mmol/l, P=0.001; 2.29 ± 0.58 vs. 2.6 ± 0.68 mmol/l, P=0.001 and 0.71 ± 0.21 vs. 0.77 ± 0.23 mmol/l, P=0.013 respectively). Patients diagnosed with MS had higher HBV DNA load than patients without MS - 1300.2 (95% CI 506.06-3440.41) vs. 7661.3 (95% CI 2008.17-29,228.06) IU/ml; P=0.011. HBI patients with TC and apolipoprotein B100 in the reference range had lower HBV DNA load than patients with high or low values of TC or apolipoprotein B100. CONCLUSION Hepatitis B patients had lower levels of total and LDL cholesterol along with a decreased apolipoprotein B100. Viral load of chronic hepatitis B patients with MS was higher than that in patients without MS.

Abstract
CONTEXT Increasing evidence has suggested an association between blood vitamin D levels and metabolic syndrome. OBJECTIVE Our objective was to determine the relationship between blood vitamin D status and metabolic syndrome in the general adult population, using a dose-response meta-analysis. DATA SOURCE We searched the PubMed, EMBASE, Web of Science, and Cochrane Library databases through July 2013 to identify relevant studies. STUDY SELECTION Observational studies, reporting risk ratios with a 95% confidence interval (CI) for metabolic syndrome in ≥3 categories of blood 25-hydroxyvitamin D [25(OH)D] levels, were selected. DATA EXTRACTION Data extraction was performed independently by 2 authors, and the quality of the studies was evaluated using the risk of bias assessment tool for nonrandomized studies. DATA SYNTHESIS The pooled odds ratio of metabolic syndrome per 25 nmol/L increment in the serum/plasma 25(OH)D concentration was 0.87 (95% CI = 0.83-0.92, I(2) = 85%), based on 16 "cross-sectional studies" and 1.00 (95% CI = 0.98-1.02, I(2) = 0%) for 2 "cohort and nested case-control studies." The dose-response meta-analysis showed a generally linear, inverse relationship between 25(OH)D levels and metabolic syndrome in the cross-sectional studies (P for linear trend < .001). CONCLUSIONS Blood vitamin D levels were associated with a risk of metabolic syndrome in cross-sectional studies but not in longitudinal studies. Randomized, clinical trials will be necessary to address the issue of causality and to determine whether vitamin D supplementation is effective for the prevention of metabolic syndrome.

Abstract
OBJECTIVE To observe the prevalence of metabolic syndrome (MS) among people with diabetes. METHODS 9 275 diabetic patients (FPG was ≥7.0 mmol/L or FPG < 7.0 mmol/L but diagnosed as diabetes or having history of diabetes, or were under hypoglycemic agents treatment) of 101 510 employees of Kailuan group who took physical check-up between 2006 and 2007, were recruited to take part in this study. Using the latest defined diagnostic criteria on MS from the 2010 hypertension guidelines, prevalence of MS among the population was analyzed, according to age and gender. Multiple logistic regression analysis was used to test the relevant factors of MS. RESULTS There were 6 105 cases with MS among the population with the prevalence as 65.8% (female:70.0%, male:64.9%). Stratified by age and gender, the prevalence rates of MS among young-age group, middle-age group and elderly group were 59.7%, 66.0% and 68.8%, respectively. The prevalence in males among the three groups was 61.4%, 64.9% and 67.0% , respectively. The prevalence rates in females among the three groups were 50.3%, 70.7% and 78.8%, respectively. Stratified by age and gender, the prevalence of waist abnormal in female was the highest (100.0%) in the youth group that with MS. However, the prevalence of dyslipidemia appeared the highest (86.3%) in males. In the elderly group with MS, the prevalence of abnormal blood pressure was the highest in both males and females, up to 96.0%. Results from multi-factor logistic regression analysis showed that cigarette smoking would increase the risk of developing MS in the youth group (OR = 1.89, 95%CI:1.09-3.28) and the risk of developing MS of man was lower than women in the middle-aged group (OR = 0.77, 95% CI:0.67-0.89; OR = 0.48, 95% CI:0.35-0.66). CONCLUSION In the diabetic population, MS prevalence in female appeared to be higher than in males. The prevalence of MS tended to increase with age. Cigarette smoking could increase the risk of MS in the youth group.

Abstract
Milk is a widely consumed beverage that is essential to the diet of several millions of people worldwide because it provides important macro- and micronutrients. Milk is recognized as being useful during childhood and adolescence because of its composition; however, its relatively high saturated fat proportion raises issues of potential detrimental effects, namely on the cardiovascular system. This review evaluates the most recent literature on dairy and human health, framed within epidemiologic, experimental, and biochemical evidence. As an example, the effects of milk (notably skimmed milk) on body weight appear to be well documented, and the conclusions of the vast majority of published studies indicate that dairy consumption does not increase cardiovascular risk or the incidence of some cancers. Even though the available evidence is not conclusive, some studies suggest that milk and its derivatives might actually be beneficial to some population segments. Although future studies will help elucidate the role of milk and dairy products in human health, their use within a balanced diet should be considered in the absence of clear contraindications.

Abstract
BACKGROUND Non-diabetic offspring from long-lived parents benefit from lowered CV risk. No study investigated the effects of parental lifespan on their progeny when offspring have T2DM. This study assessed CV and metabolic features of T2DM offspring according to parental lifespan. PATIENTS & METHODS 558 T2DM patients were questioned on parental longevity (paternal and/or maternal lifespan ≥ 80 years); mean age 66 (11) years; male:female 66:34; divided into 6 groups: long-lived father [LLF] (n = 143); short-lived father [SLF] (n = 262); long-lived mother [LLM] (n = 229); short-lived mother [SLM] (n = 176); long-lived father and long-lived mother [LLF & LLM] (n = 82); and short-lived father and/or short-lived mother [SLF &/or SLM] (n = 323). RESULTS Age was similar in [LLF & LLM] and [SLF &/or SLM]. Diabetes duration was longer in [SLF &/or SLM] (p 0.0073). Body composition, hypertension, hepatic steatosis and metabolic syndrome (MetS) were similar in both groups, [SLF &/or SLM] having a higher MetS score: 3.79 (1.12) vs. 3.48 (1.12) (p 0.0257). Fasting insulinemia was higher in [SLF &/or SLM] (p 0.0001), who were more insulin resistant (+10%: p 0.0440). HbA1c was higher (+0.36%) in [SLF &/or SLM] (p 0.0138). LDL-C; non-HDL-C; and apoB100 were similar in both groups, whereas HDL-C and apoA-I were higher in [LLF & LLM] (p 0.0233 and p 0.0179). Prevalence and severity of atherogenic dyslipidemia were raised in [SLF &/or SLM], by 53% (prevalence) and 13% (log[TG]/HDL-C) (p 0.0172 and p 0.0067). CONCLUSION Bilateral reductions in parental longevity are linked to unfavorable cardiometabolic phenotype in T2DM descendants, with worsened insulin resistance and atherogenic dyslipidemia among 1st-degree offspring.

Abstract
This study aimed to investigate the association between serum levels of 25-hydroxyvitamin D [25(OH)D] and metabolic syndrome along with its associated risk factors in Korean postmenopausal women. This study was performed using data from the KNHANES 2008–2010 study and included 4,364 postmenopausal Korean women. Clinical and other objective characteristics, seasonality, and presence of metabolic syndrome with its five components were evaluated and correlated with the serum levels of 25(OH)D. Although no statistically significant associations were observed between the levels of serum 25(OH)D and the prevalence of metabolic syndrome, the adjusted OR for elevated blood pressure, elevated triglycerides (TGs), and reduced high-density lipoprotein cholesterol (HDL-C) showed tendency to decrease sequentially as tertiles of serum 25(OH)D levels increased (p for trends = 0.066, 0.043, and 0.010, respectively). Women in the highest tertile of serum 25(OH)D showed a significant decrease in the prevalence of elevated blood pressure, elevated TGs, and reduced HDL-C as compared with those in the lowest tertile of serum 25(OH)D (p = 0.020, 0.014, and 0.002, respectively). Based on these results, we consider that adequate serum levels of 25(OH)D in Korean postmenopausal women may not entirely indicate a lower risk of developing metabolic syndrome. However, adequate serum levels of 25(OH)D are significantly associated with a decrease in elevated blood pressure, elevated TGs, and reduced HDL-C levels in postmenopausal women.

Abstract
Background Metabolic Syndrome (MetS) is a complex disorder defined as a cluster of interconnected risk factors such as hypertension, dyslipidemia, obesity and high blood glucose levels. Premorbid metabolic syndrome (PMetS) is defined by excluding patients with previously diagnosed cardiovascular disease or diabetes mellitus from those suffering MetS. We aimed to determine the prevalence of PMetS in a working population, and to analyse the relationship between the diagnostic criteria of the International Diabetes Federation (IDF) and of the National Cholesterol Education Program Adult Treatment Panel III (ATPIII). The relationship between the presence of PMetS and cardiovascular risk factors was also analysed. Research Methodology/Findings A cross-sectional study was conducted in 24,529 male and 18,736 female Spanish (white western European) adult workers (20–65 years) randomly selected during their work health periodic examinations. Anthropometrics, blood pressure and serum parameters were measured. The presence of MetS and PMetS was ascertained using ATPIII and IDF criteria. Cardiovascular risk was determined using the Framingham-REGICOR equation. The results showed MetS had an adjusted global prevalence of 12.39% using ATPIII criteria and 16.46% using IDF criteria. The prevalence of PMetS was slightly lower (11.21% using ATPIII criteria and 14.72% using IDF criteria). Prevalence in males was always higher than in females. Participants with PMetS displayed higher values of BMI, waist circumference, blood pressure, glucose and triglycerides, and lower HDL-cholesterol levels. Logistic regression models reported lower PMetS risk for females, non-obese subjects, non-smokers and younger participants. Cardiovascular risk determined with Framingham-REGICOR was higher in participants with PMetS. Conclusions PMetS could be a reliable tool for the early identification of apparently healthy individuals who have a significant risk for developing cardiovascular events and type 2 diabetes.

Abstract
Crystal arthropathies are among the most common causes of painful inflammatory arthritis. Gout, the most common example, has been associated with cardiovascular and renal disease. In recent years, evidence for these associations and those involving other comorbidities, such as the metabolic syndrome, have emerged, and the importance of asymptomatic hyperuricemia has been established. In this review, an update on evidence, both experimental and clinical, is presented, and associations between hyperuricemia, gout, and several comorbidities are described. Causality regarding calcium pyrophosphate arthropathy and associated comorbidities is also reviewed.

Abstract
There is global diversity in the prevalence of uric acid (UA) nephrolithiasis. UA nephrolithiasis comprises 8-10 % of all kidney stones in the United States. However, its prevalence is higher in patients with type 2 diabetes mellitus and those with obesity. Three significant urinary abnormalities have been described as the main etiologic factors for the development of UA nephrolithiasis; low urinary pH, hyperuricosuria and low urinary volume. However, an unduly acidic urine below the ionization constant of uric acid (pKa < 5.5) increases the urinary content of undissociated uric acid and thereby uric acid precipitation. Previous studies have shown the two major pathogenic mechanisms for unduly urinary pH are increased net acid excretion (NAE) and reduced renal ammonium (NH4 (+)), with a combination resulting in overly acidic urine. The impaired ammonium excretion has been demonstrated in a steady state in 24-hour urine and also following an oral ammonium chloride (NH4Cl) challenge to amplify ammoniogenic defects in this population. Similar abnormalities have been disclosed in normal populations and also in T2DM populations without kidney stones. To date, the underlying mechanism of increased acid production, source and nature of putative organic acid anions have not been fully elucidated. One plausible mechanism is the production of organic acid by intestinal and aerobic metabolism. This may occur in obese, diabetic and uric acid stone formers due to the differences in gut microflora.

Abstract
INTRODUCTION Greater adherence to a Mediterranean diet is linked to lower risk for cardiovascular morbidity/mortality in studies of Mediterranean cohorts, older subjects, and/or those with existing health conditions. No studies have examined the effects of this dietary pattern in younger working populations in the United States. We investigated the effects of Mediterranean diet adherence on cardiovascular disease (CVD) biomarkers, metabolic syndrome and body composition in an occupationally active, non-Mediterranean cohort. METHODS A cross-sectional study in a cohort of 780 career male firefighters, ages 18 years or older, from the United States Midwest. No dietary intervention was performed. A modified Mediterranean diet score (mMDS) was developed for assessment of adherence to a Mediterranean dietary pattern from a previously administered life-style questionnaire that examined pre-existing dietary habits. Clinical data from fire department medical examinations were extracted and analyzed. RESULTS Obese subjects had significantly lower mMDS, and they reported greater fast/take-out food consumption (p<0.001) and intake of sweetened drinks during meals (p = 0.002). After multivariate adjustment, higher mMDS was inversely related to risk of weight gain over the past 5 years (odds ratio [OR]: 0.57, 95% confidence interval [CI]: 0.39-0.84, p for trend across score quartiles: 0.01); as well as the presence of metabolic syndrome components (OR: 0.65, 95% CI: 0.44-0.94, p for trend across score quartiles: 0.04). Higher HDL-cholesterol (p = 0.008) and lower LDL-cholesterol (p = 0.04) were observed in those with higher mMDS in linear regression after multivariate adjustment for age, BMI and physical activity. CONCLUSIONS In a cohort of young and active US adults, greater adherence to a Mediterranean-style dietary pattern had significant inverse associations with metabolic syndrome, LDL-cholesterol and reported weight gain, and was significantly and independently associated with higher HDL-cholesterol. Our results support the potential effectiveness of this diet in young, non-Mediterranean working cohorts, and justify future intervention studies.

Abstract
We performed a systematic review and meta-analysis on the association of metabolic syndrome with endometrial cancer. A systematic literature search of electronic databases (Medline, ISI Web of Knowledge and Scopus) was conducted and complemented by cross-referencing to identify studies published before 31 January 2013. Core items of identified studies were independently extracted by two reviewers, and results were summarized by random effects meta-analysis. We identified six studies, which reported on 3,132 cancer cases. Metabolic syndrome was associated with an increased risk of endometrial cancer (RR: 1.89, 95 % CI 1.34-2.67, P < 0.001), with significant heterogeneity among studies (I (2) = 92 %, P < 0.001), but no indication for publication bias in the Egger's test (P = 0.240). A sensitivity analysis omitting two studies produced no heterogeneity (I (2) = 0 %) and attenuated the association (RR: 1.39, 1.31-1.48, P < 0.001). The risk estimates for any single factor of the syndrome were 2.21 (P < 0.001) for higher values of body mass index and/or waist, 1.81 (P = 0.044) for hyperglycemia, 1.81 (P = 0.024) for higher blood pressure values, and 1.17 (P < 0.001) for high triglyceride levels; there was no significant association with low HDL-cholesterol. Metabolic syndrome is associated with an increased risk of endometrial cancer; among the components of the syndrome, obesity/high waist is that more strongly associated with endometrial cancer.

Abstract
Insulin stimulates proliferation of thyroid cells in culture. The presence of insulin resistance (IR) is associated with larger thyroid gland volume and an increased prevalence of thyroid nodules. The aim of this study was to investigate the presence of any possible association between IR and thyroid cancer. Forty-one patients with diffuse thyroid cancer (Group 1) were matched for age and gender with 41 patients with nodular goiter (Group 2). Both groups were compared in terms of frequency of IR, as estimated by the homeostasis model assessment, as well as other parameters of the metabolic syndrome (MetS). Fourteen patients (34.1 %) in each group had MetS. Twelve patients (29.3 %) in group 1 had IR compared to 10 (24.4 %) in group 2. Mean HOMA-IR scores in group 1 and 2 were 2.5 ± 2.2 and 1.8 ± 1.1, respectively. Thirty-two patients (78 %) in group 1 had a body mass index (BMI) of more than 25 compared to 33 patients (80.5 %) in group 2. The difference between groups with regard to HOMA-IR, the frequency of IR, BMI, and any of the parameters of MetS was statistically insignificant (p > 0.05). A subgroup analysis based on tumor size did not reveal a significant difference between patients with microcarcinoma (≤10 mm) and macrocarcinoma (>10 mm) in terms of any of the study parameters (p > 0.05). Neither MetS nor IR was a significant risk factor for thyroid cancer following logistic regression analysis (p > 0.05). IR is not more prevalent in patients with thyroid cancer. Some other pathologic mechanisms may be more prominent during thyroid carcinogenesis.

Abstract
OBJECTIVE Ectopic fat accumulation within the heart and the liver are linked to an increased cardiovascular risk. Ultrasound-measured cardiac and liver steatosis are easily accessible markers of intra-organ ectopic fat accumulation. The hypothesis that echocardiographic epicardial fat thickness is independently associated with nonalcoholic fatty liver disease (NAFLD) in obese subjects is tested. DESIGN AND METHODS Sixty-two obese (BMI > 30 kg m⁻²) subjects with ultrasonographic evidence of NAFLD and 62 control obese subjects without history or signs of NAFLD underwent echocardiographic epicardial fat thickness measurement. RESULTS Epicardial fat thickness was significantly higher (P < 0.01) in obese subjects with NAFLD when compared to those without NAFLD. Epicardial fat thickness was significantly higher (9.7 ± 0.2 vs. 8 ± 0.7 mm, P < 0.01) in subjects with severe (ultrasound score 3) than those with moderate (score 2) liver steatosis. Among waist circumference and BMI, epicardial fat thickness resulted in the best independent correlate of liver steatosis (R² = 0.77, P < 0.001). CONCLUSIONS Our study suggests that epicardial fat is a good predictor of liver steatosis in obese subjects. Echocardiographic epicardial fat predicts ultrasound-measured fatty liver better than BMI or waist circumferences does. Patients with severe fatty liver infiltration presented with the highest amount of cardiac fat accumulation.

Abstract
INTRODUCTION Metabolic syndrome (MetS) and depression are considered important risk factors for diabetes and cardiovascular disease. Recent evidence suggests that depression can be an important predictor of MetS. Data on the association between anxiety and MetS remain mixed. In a large primary care based community sample we investigated an association of depressive and anxiety disorders and symptoms with MetS. METHODS A total of 1115 (51% men, mean age 62.0 ± 9.6 years) randomly selected individuals of 45 years and older were evaluated for: (i) MetS using the World Health Organization (WHO), National Cholesterol Education Program Adult Treatment Panel III (NCEP/ATP III) and International Diabetes Federation (IDF) criteria; (ii) current major depressive episode (MDE) and current generalized anxiety disorder (GAD), the Mini International Neuropsychiatric interview; (iii) lifetime MDE; and (iv) symptoms of depression and anxiety, the Hospital Anxiety and Depression scale (HADS). Socio-demographic characteristics (education, residence, marital status and social status) and medical histories (physical activity, smoking status, alcohol consumption and histories of myocardial infarction and stroke) were also evaluated. RESULTS After adjusting for socio-demographic status, medical histories and current GAD, current MDE and lifetime MDE were associated with greater prevalence of MetS according to the WHO criteria (OR=1.7, 95%CI [1.1-2.7] and OR=3.7, 95%CI [2.4-5.7], respectively, p ≤ 0.001). Lifetime MDE was also associated with MetS according to the IDF and NCEP/ATP III criteria. On the other hand, current GAD was not associated with MetS in multivariate regression models when adjusted for current MDE. Similar results were obtained when evaluating an association between depression/anxiety symptoms and MetS, since elevated depressive, but not anxiety, symptoms were independently associated with MetS. CONCLUSIONS Depressive, but not anxiety, disorders and symptoms are associated with greater prevalence rate of MetS. Assessment and management of MetS risk factors should be considered in depressed individuals.

Abstract
Lactating compared with nonlactating women display more favorable metabolic parameters, including less atherogenic blood lipids, lower fasting and postprandial blood glucose as well as insulin, and greater insulin sensitivity in the first 4 months postpartum. However, direct evidence demonstrating that these metabolic changes persist from delivery to postweaning is much less available. Studies have reported that longer lactation duration may reduce long-term risk of cardiometabolic disease, including type 2 diabetes, but findings from most studies are limited by self-report of disease outcomes, absence of longitudinal biochemical data, or no assessment of maternal lifestyle behaviors. Studies of women with a history gestational diabetes mellitus (GDM) also reported associations between lactation duration and lower the incidence of type 2 diabetes and the metabolic syndrome. The mechanisms are not understood, but hormonal regulation of pancreatic β-cell proliferation and function or other metabolic pathways may mediate the lactation association with cardiometabolic disease in women.

Abstract
INTRODUCTION Metabolic syndrome (MetS) is a combination of risk markers that appear to promote the development of chronic disease. We examined the burden of MetS in Canada through its current and projected association with chronic disease. METHODS We used measures from the Canadian Health Measures Survey 2007-2009 to identify the prevalence of MetS in Canadian adults and examine associations between sociodemographic factors and major chronic diseases. We estimated the projected cumulative incidence of diabetes and percent risk of a fatal cardiovascular event using the Diabetes Population Risk Tool (DPoRT) and Framingham algorithms. RESULTS After adjusting for age, we found that 14.9% of Canadian adults had MetS. Rates were similar in both sexes, but higher in those who are non-Caucasian or overweight or obese (p < .001 for all three). The importance of MetS for public health was demonstrated by its significant association with chronic disease relative to the general population, particularly for diagnosed (11.2% vs. 3.4%) and undiagnosed (6.0% vs. 1.1%) type 2 diabetes. The ten-year incidence estimate for diabetes and mean percent risk of a fatal cardiovascular disease (CVD) event were higher in those with MetS compared to those without (18.0% vs. 7.1% for diabetes, and 4.1% vs. 0.8% for CVD). CONCLUSION MetS is prevalent in Canadian adults and a high proportion of individuals with MetS have diagnosed or undiagnosed chronic conditions. Projection estimates for the incidence of chronic disease associated with MetS demonstrate higher rates in individuals with this condition. Thus, MetS may be a relevant risk factor in the development of chronic disease.

Abstract
To propose a simplified tool to recognize subjects with a moderate risk to develop type 2 diabetes mellitus (Type 2 DM): this method would take into account only variables from metabolic syndrome definitions which are cheaply assessable. A total of 3,003 employees without diabetes in Italy who attended one annual health examination between 2009 and 2012 were enrolled in this cross-sectional study. A questionnaire was administered along with the annual health examination to record personal and familiar anamnesis. To identify Type 2 DM-prone individuals, the diabetes predictive model by Stern MP et al. was used. Then a multiple logistic regression model was developed using the predicted probability 20%+ of developing Type 2 DM as the outcome variable and a panel of easily measurable continuous baseline characteristics as explanatory variables (waist circumference, WC; body mass index, BMI; and systolic blood pressure, SBP). The optimism-adjusted area under the curve of the proposed model receiver-operating characteristic (ROC) is 0.90. The effects of the explanatory variables on the presumed Type 2 DM risk are summarized by the following adjusted odds ratio values: 2.65 for SBP (P < 0.001), 2.01 for WC (P = 0.04) and 4.64 for BMI (P < 0.001). The satisfactory ROC of the proposed model suggests the importance of simple assessments in the prognostic information on Type 2 DM risk. Such ease of use may be particularly relevant in populations facing the transition from traditional to industrial food who do not have a sophisticated health service yet.

Abstract
BACKGROUND The metabolic syndrome (MetS) and/or its individual components have been linked to the development of cancer. Recent studies have suggested a similar link to hepatocellular carcinoma (HCC). The aim of this study was to evaluate the direction and magnitude of the association between the MetS and HCC. METHODS Two reviewers independently conducted a systemic search to identify the available evidence from databases from January 1980 to June 2012. Search terms included "Metabolic syndrome," "insulin resistance syndrome," "metabolic abnormalities" combined with "hepatocellular carcinoma," and "liver cancer." No language restriction was applied to the search. Only studies reporting an effect measure for the association between MetS and HCC were eligible for inclusion. Publication bias was assessed using the Begg and Egger tests, with a visual inspection of funnel plot. All analyses were performed using Comprehensive Meta-analysis version 2 software. RESULTS Four studies (3 cohort and 1 case control) with a total of 829,651 participants were included in the analysis. The age range of participants was between 30 and 84 years. The combined analysis showed an overall 81% increased risk of HCC in cases with MetS (relative risk, 1.81; 95% confidence interval, 1.37-2.41). After excluding the single case-control study from analysis, the overall risk ratio remained statistically significant (relative risk, 1.49; 95% confidence interval, 1.27-1.74). Funnel plot inspection, Begg and Egger tests showed no evidence of publication bias for combined analysis. CONCLUSIONS Though studies are scarce, currently available epidemiologic data are suggestive of significantly higher risk of HCC among patients with MetS.

Abstract
BACKGROUND Whether apolipoproteins (Apos) are better cardiovascular disease (CVD) markers than metabolic syndrome (MS) is widely debated. Measurement of Apo B is standardized, simple, and inexpensive and does not require fasting. The aim of this study was to compare the ability of nontraditional CVD markers such as Apo B, Apo B/Apo A, non-high-density lipoprotein cholesterol (HDL-C), vitamin D, and homeostasis model assessment of insulin resistance (HOMA-IR) to identify children with MS. SUBJECTS AND METHODS A cross-sectional study of 355 Argentinean Koya schoolchildren (166 boys) 9.6±2.3 years old was performed in November 2011. Anthropometric measures, blood pressure, Tanner stages, and serum levels of glucose, lipids, insulin, Apo A, Apo B, and vitamin D were measured. RESULTS The prevalence of overweight/obesity was 10.7% (n=38), and that of underweight was 14.6% (n=52) using Centers for Disease Control and Prevention criteria. The prevalence of central obesity was 10.9% (38/355), high triglycerides was 11.1% (39/355), low HDL-C was 44.9% (158/355), hypertension was 12.8% (45/355), hyperglycemia was 0.3% (1/355), and MS was 4.2% (15/355). Several multiple logistic regression analyses showed that MS was significantly associated with HOMA-IR (odds ratio [OR], 3.6 [95% confidence interval (CI) 1.51-8.52]), non-HDL-C (OR, 1.03 [95% CI 1.007-1.049]), Apo B (OR, 1.06 [95% CI 1.03-1.09]), and Apo B/Apo A (OR, 78.3 [95% CI 3.67-1,674.4]) adjusted for age and gender. Furthermore, the areas under the receiver operator characteristic curves were as follows: Apo B, 0.77 (95% CI 0.63-0.90); Apo B/Apo A, 0.76 (95% CI 0.63-0.88); non-HDL-C, 0.72 (95% CI 0.57-0.85); and HOMA-IR, 0.69 (95% CI 0.49-0.90). These values indicate that these variables were acceptable predictors for MS. CONCLUSIONS This is the first study of nontraditional markers in South American Indian children. MS was associated with multiple nontraditional markers of future CVD risk such as non-HDL-C, Apo B, and Apo B/Apo A. However, Apo B was the best predictor for MS, suggesting that it could be used as a risk marker of future CVD in this community.

Abstract
The estimated population of the South and Central America (SACA) Region is 467.6 million and 64% is in the age range of 20-79 years but the population pyramid and age distribution are changing. The average prevalence of diabetes in the Region is 8.0% and is expected to reach 9.8% by the year 2035. Prevalence is much lower in rural settings than in urban and the differences attributed to lifestyle changes may be a target for intervention. The indigenous population is a particularly vulnerable group needing special attention. On average, 24% of the adult cases with diabetes are undiagnosed but in some countries this is still as high as 50%. Health expenditure due to diabetes in the Region is around 9% of the global total. Inadequate glycemic control, defined as HbA1c >7%, is a strong predictor of chronic complications which increase resource use in the Region and less than half of the patients enrolled in diabetes care programmes are at target. Fifty percent or more of the adult population is overweight/obese and around one third of the adult population has metabolic syndrome using regional cutoffs for waist circumference. The number of people with IGT is almost equal to those with diabetes presenting an additional challenge for prevention. Children with type 1 diabetes represent only 0.2% of the total population with diabetes but the incidence may be increasing. In many places they have limited access to insulin, and even when available, it is not used appropriately. The available epidemiological data provide the background to act in developing national diabetes programmes which integrate diabetes care with cardiovascular prevention and promote diabetes prevention as well.
