Abstract
OBJECTIVES Obesity-induced insulin resistance (IR) is known to influence hepatic cytokines (hepatokines), including fibroblast growth factor (FGF-21), fetuin-A, and chemerin. This study aimed to investigate the association between hepatokines and markers of endothelial dysfunction and vascular reactivity in obese adolescents. METHODS A total of 45 obese adolescents were categorized into three groups based on glucose tolerance: normal glucose tolerance (NGT), prediabetes (PD), and type 2 diabetes (T2D). We examined the relationships between FGF-21, fetuin-A, and chemerin with endothelial markers (plasminogen activator inhibitor-1 [PAI-1], intercellular adhesion molecule-1 [ICAM-1], and vascular cell adhesion marker-1 [VCAM-1]) and vascular surrogates (brachial artery reactivity testing [BART] and peak reactive hyperemia [PRH]). RESULTS Obese adolescents (age 16.2±1.2 years; 62 % female, 65 % Hispanic) with NGT (n=20), PD (n=14), and T2D (n=11) had significant differences between groups in BMI; waist-hip ratio (p=0.05), systolic BP (p=0.008), LDL-C (p=0.02), PAI-1 (p<0.001). FGF-21 pg/mL (mean±SD: NGT vs. PD vs. T2D 54±42; 266±286; 160±126 p=0.006) and fetuin-A ng/mL (266±80; 253±66; 313±50 p=0.018), were significantly different while chemerin ng/mL (26±5; 31±10; 28±2) did not significantly differ between the groups. Positive correlations were found between chemerin and both PAI-1 (r=0.6; p=0.05) and ICAM-1 (r=0.6; p=0.05), FGF-21 and PAI-1 (r=0.6; p<0.001), and fetuin-A with TNFα (r=-0.4; p=0.05). Negative correlations were found between chemerin and PRH (r= -0.5; p=0.017) and fetuin-A and PRH (r=-0.4; p=0.05). CONCLUSIONS In our cohort, IR predicted higher FGF-21 levels suggesting a linear relationship may exist between the two parameters. Hepatokines can augment alterations in the microvascular milieu in obese adolescents as demonstrated by their associations with the markers PAI-1, ICAM-1, and PRH.

Abstract
BACKGROUND Multiple organizations have published guidelines for the screening and treatment of obesity and related comorbidities in youth, including the use of anti-obesity medications (AOM). This study aimed to determine which paediatric patients: (1) receive a diagnostic code for obesity; (2) are most likely to be screened for hyperlipidaemia, non-alcoholic fatty liver disease, and type 2 diabetes mellitus; and (3) are most likely to be prescribed AOM. METHODS A cohort of 35 898 patients 9 years 4 months to 17 years 6 months of age with a BMI > 30 or greater than the 95th% on three separate outpatient encounters was generated using the TriNetX database. Logistic regression models were used to estimate the associations between demographics in the study population and the likelihood of diagnosis of obesity, screening for comorbidities, and prescription of AOMs. RESULTS Asian, Black, and Hispanic youths had increased odds of having a diagnosis of obesity and being screened for all three comorbidities. Documentation of obesity was associated with increased odds of screening for all comorbidities. Female sex, documentation of obesity, and higher BMIs were associated with increased odds of being prescribed AOMs. Black and Native American races decreased the likelihood of being prescribed AOM. CONCLUSIONS Management of obesity in terms of documentation of disease, screening for comorbidities, and initiation of AOM continues to fall short of the guidelines put forth by multiple organizations. Race/ethnicity, sex, and BMI correlate with differences in care provided to obese paediatric patients. Further research is needed to identify the barriers to and causes of these disparities.

[PMID: 37240998 DOI: 10.3390/jpm13050828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 05/08/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023] Open
Abstract
The precise association of serum leptin (Lep) with the body mass index (BMI) and blood pressure (BP) is not well known for understanding their involvement in health and disease. Hence, the present study was conducted to investigate the association of BP, BMI and serum Lep levels in young normal-weight (NW) and overweight (OW) male Saudi students. The NW (n: 198) and OW (n: 192) male subjects in the age range of 18-20 years were consulted. The BP was measured with a mercury sphygmomanometer. Leptin Human ELISA Kits were employed for the determination of the serum Lep levels. The mean ± SD values of BMI (kg/m2), Lep (ng/mL), systolic BP (SBP; mmHg), and diastolic BP (DBP; mmHg) all showed significant differences for young OW vs. NW subjects as: 27.52 ± 1.42 vs. 21.49 ± 2.03; 10.70 ± 4.67 vs. 4.68 ± 1.91; 121.37 ± 2.59 vs. 118.51 ± 1.54 and 81.44 ± 1.97 vs. 78.79 ± 1.44, respectively. All associations (among BMI, Lep, SBP and DBP) showed a positive linear and significant correlation, except the nonsignificant correlation of BMI and SBP for the NW group. Other variables showing significant variation for NW vs. OW subjects were: interleukin-6, high sensitivity C-reactive protein, apelin (APLN) and resistin. Serum APLN correlated significantly with Lep, BMI, SBP and DBP in lower and higher levels of BMI, with considerable progressive patterns in both the NW and OW groups and subgroups. The present study in young Saudi male students presents significant variations for BP and serum leptin levels, and a significant positive linear association among serum leptin, BMI and BP.

Abstract
Background Obesity and hypertension represent serious health issues affecting the pediatric population with increasing prevalence. Hypovitaminosis D has been suggested to be associated with arterial hypertension. Serotonin by modulating nitric oxide synthase affect blood pressure regulation. The biological mechanism by which vitamin D specifically regulates serotonin synthesis was recently described. The aim of this paper is to determine the associations between vitamin D, serotonin, and blood pressure in obese children. Methods One hundred and seventy-one children were enrolled in the prospective cross-sectional study. Two groups of children divided according to body mass index status to obese (BMI ≥95th percentile; n = 120) and non-obese (n = 51) were set. All children underwent office and ambulatory blood pressure monitoring and biochemical analysis of vitamin D and serotonin. Data on fasting glucose, insulin, HOMA, uric acid, and complete lipid profile were obtained in obese children. Results Hypertension was found only in the group of obese children. Compared to the control group, obese children had lower vitamin D and serotonin, especially in winter. The vitamin D seasonality and BMI-SDS were shown as the most significant predictors of systolic blood pressure changes, while diastolic blood pressure was predicted mostly by insulin and serotonin. The presence of hypertension and high-normal blood pressure in obese children was most significantly affected by vitamin D deficiency and increased BMI-SDS. Conclusions Dysregulation of vitamin D and serotonin can pose a risk of the onset and development of hypertension in obese children; therefore, their optimization together with reducing body weight may improve the long-term cardiovascular health of these children.

Abstract
Non-alcoholic fatty liver disease (NAFLD) and its progressive subtype non-alcoholic steatohepatitis (NASH) are the most prevalent liver diseases, often leading to hepatocellular carcinoma (HCC). This review aims to describe the present knowledge of the risk factors responsible for the development of NAFLD and NASH. I performed a literature review identifying studies focusing on the complex pathogenic pathway and risk factors of NAFLD and steatohepatitis. The relationship between NAFLD and metabolic syndrome is well established and widely recognized. Obesity, dyslipidemia, type 2 diabetes, hypertension, and insulin resistance are the most common risk factors associated with NAFLD. Among the components of metabolic syndrome, current evidence strongly suggests obesity and type 2 diabetes as risk factors of NASH and HCC. However, other elements, namely gender divergences, ethnicity, genetic factors, participation of innate immune system, oxidative stress, apoptotic pathways, and adipocytokines, take a leading role in the onset and promotion of NAFLD. Pathophysiological mechanisms that are responsible for NAFLD development and subsequent progression to NASH are insulin resistance and hyperinsulinemia, oxidative stress, hepatic stellate cell (HSC) activation, cytokine/adipokine signaling pathways, and genetic and environmental factors. Major pathophysiological findings of NAFLD are dysfunction of adipose tissue through the enhanced flow of free fatty acids (FFAs) and release of adipokines, and altered gut microbiome that generate proinflammatory signals and cause NASH progression. Understanding the pathophysiology and risk factors of NAFLD and NASH; this review could provide insight into the development of therapeutic strategies and useful diagnostic tools.

Abstract
S-Klotho is perceived as a biomarker of healthy aging that has been shown to be inversely associated with cardiometabolic risk in elderly individuals. The aim of this study was to test if s-Klotho level is associated with cardiometabolic risk markers in younger healthy men in order to verify the possible role of s-Klotho level as an early marker of cardiometabolic risk. A cross-sectional study was conducted among 186 healthy men (Mage=35.33, SDage=3.47) from a Western urban population. Serum basal levels of s-Klotho, lipid profile, homocysteine, glycemia markers, C-reactive protein, liver transaminases and creatinine were evaluated. Also, blood pressure was measured and cardiometabolic risk score and homeostatic model assessment for insulin resistance (HOMA-IR) were calculated. Testosterone and cortisol levels, self-reported psychological stress, physical activity, smoking in the past, alcohol use and body adiposity were controlled for. We found no relationship between levels of s-Klotho and physiological markers of cardiometabolic risk in the studied population. The results were similar when controlled for adiposity, testosterone level, physical activity, alcohol use and smoking in the past. We suggest that s-Klotho level is not an early marker of cardiometabolic risk in younger middle-aged healthy men.

Abstract
Herbal and home remedies are widely used worldwide especially those for weight loss. The prevalence of overweight and obesity in Saudi Arabia has highly elevated during the past decades. People in Saudi Arabia preferred the usage of remedies more than standard medicine. Therefore, we conducted this study to assess the use of weight reduction herbal and home remedies in Tabuk, North West Saudi Arabia. Data about weight-loss herbal remedies were collected from major local herbalist shops. In addition, inherited weight-loss herbal and household remedies were collected. Data collected included composition, method of preparation, method of use, and any reported side effects. Some of these remedies were used either alone or in combination. Majority of these ingredients were boiled in water to be drunk or directly added to food. Most of these mixtures were taken before food to reduce appetite. Most of these herbs were recorded to produce side effects. Mainly people suffer from gastric symptoms and headache. Many natural herbal and home remedies are still in use in Tabuk for weight reduction. Many of these remedies lack important scientific evidence for their usage, effectiveness, or safety.

Abstract
OBJECTIVES Obesity and being overweight among adolescents pose a significant problem and are known to cause several physical and biochemical disorders during adulthood. This study was designed to identify the biomarkers of obesity and describe associations with selected metabolic disorders of obesity among Sri Lankan adolescents. METHODS The present study compared the characteristics of obese (n = 121) and normal weight (n = 263) adolescents, including sociodemographic, anthropometric, and selected biochemical parameters (e.g., lipid profile, serum leptin, adiponectin, and high-sensitivity C-reactive protein [hs-CRP]). An enzyme-linked immunosorbent assay technique and fully automated clinical chemistry analyzer were used to analyze the biochemical parameters among adolescents ages 10 to 16. RESULTS The mean age of the sample was 13.1 y [standard deviation (SD): 1.9 y], and the male-to-female ratio 1:1. The mean weight of obese children was 55.70 kg (SD: 14.82 kg), which was significantly higher than that of children of normal weight [41.63 kg (SD: 7.88 kg)]. Total cholesterol, triacylglycerol, and low-density lipoprotein cholesterol levels were significantly higher (P = 0.000) among obese adolescents compared with those of normal weight. High-density lipoprotein cholesterol was significantly lower among obese adolescents. Serum leptin and hs-CRP were higher among obese adolescents, but adiponectin was lower. In the multivariate analysis, owing to confounding effects among the tested adipokines, serum leptin was the only predictor of an abnormal lipid profile. CONCLUSIONS Serum leptin, adiponectin, and hs-CRP were found to be reliable biomarkers of predicting adiposity related metabolic disorders in adolescents. Obese adolescents showed disorders in the lipid metabolism with abnormal lipid profiles compared with children of normal weight.

Abstract
PURPOSE Hepatokines are proteins produced by the liver and involved in regulating glucose and lipid metabolism. However, their role as the biomarkers of intrahepatic lipid content is not clear. The aim of the study was to evaluate the serum concentration of selected hepatokines: fibroblast growth factor-21 (FGF-21), selenoprotein P (SELENOP) and sex hormone-binding globulin (SHBG) in obese children. PATIENTS AND METHODS The cross-sectional study included 86 obese children with suspected liver disease. Nonalcoholic fatty liver disease (NAFLD) was diagnosed in children with liver steatosis in ultrasound with elevated alanine aminotransferase (ALT) serum activity and excluded other liver diseases. The total intrahepatic lipid content (TILC) was assessed by magnetic resonance proton spectroscopy (1H-MRS). RESULTS The concentration of FGF-21 and SELENOP was significantly higher and SHBG significantly lower in children with NAFLD compared to controls. Only FGF-21 level was significantly higher in NAFLD children than in obese patients without NAFLD. The significant positive correlation of FGF-21 with ALT, gamma glutamyltransferase (GGT), triglycerides, homeostatic model assessment-insulin resistance (HOMA-IR), the degree of liver steatosis in ultrasound and TILC in 1H-MRS were found. The ability of serum FGF-21 to diagnose severe liver steatosis was significant. CONCLUSIONS FGF-21 can be considered as a suitable biomarker in predicting TILC and fatty liver in obese children.

Abstract
OBJECTIVE To review findings on chemerin and factors related to cardiovascular risk in children and adolescents. DATA SOURCE A systematic review was performed, according to the standards proposed by the PRISMA guideline, on PubMed, Science Direct, and Lilacs databases. The descriptor "chemerin" was used in combination with "children" and "adolescent", no time limit applied. The research encompassed only original articles written in English, conducted with human subjects - the adult and elderly populations excluded -, as well as literature reviews, brief communications, letters, and editorials. DATA SYNTHESIS After independent analyses of the studies by two reviewers, seven articles meeting the eligibility criteria, published between 2012 and 2016, remained for the review. Cross-sectional, prospective, cohort, and case-control studies were included. The importance of chemerin adipokines on the risk factors for cardiovascular disease is demonstrated by its association with obesity and diabetes mellitus, as well as clinical, anthropometric, and biochemical parameters. However, the strength of evidence from these studies is relatively low, due to their heterogeneity, with several limitations such as small samples and consequent lack of representativeness, lack of standardization in dosage methods, cross-sectional design of most studies, and impossibility of extrapolating results. CONCLUSIONS The deregulation of chemerin caused by increased adipose tissue may contribute to the development of cardiovascular diseases, suggesting that this adipokine may play a significant role in early identification of individuals at risk.

Abstract
PURPOSE The aim of this study was to investigate the possible relationship among insulin resistance (IR), endothelial dysfunction, and alteration of adipokines in Mexican obese adolescents and their association with metabolic syndrome (MetS). MATERIALS AND METHODS Two hundred and twenty-seven adolescents were classified according to the body mass index (BMI) (control: N=104; obese: N=123) and homeostasis model of the assessment-insulin resistance index (HOMA-IR) (obese with IR: N=65). The circulating concentrations of leptin, adiponectin, soluble intercellular adhesion molecule-1 (sICAM-1), and IR were determined by standard methods. RESULTS The obese adolescents with IR presented increased presence of MetS and higher circulating concentrations in sICAM-1 in comparison with the obese subjects without IR. The lowest concentrations of adiponectin were observed in the obese with IR. In multivariate linear regression models, sICAM-1 along with triglycerides, total cholesterol, and waist circumference was strongly associated with HOMA-IR (R2=0.457, P=0.008). Similarly, after adjustment for age, BMI-SDS, lipids, and adipokines, HOMA-IR remained associated with sICAM-1 (R2=0.372, P=0.008). BMI-SDS was mildly associated with leptin (R2=0.176, P=0.002) and the waist circumference was mild and independent determinant of adiponectin (R2=0.136, P=0.007). CONCLUSIONS Our findings demonstrated that the obese adolescents, particularly the obese subjects with IR exhibited increased presence of MetS, abnormality of adipokines, and endothelial dysfunction. The significant interaction between IR and endothelial dysfunction may suggest a novel therapeutic approach to prevent or delay systemic IR and the genesis of cardiovascular diseases in obese patients.

Abstract
BACKGROUND Obesity-related childhood hypertension is associated with disturbances of serum lipids, but less is known about distribution of lipoprotein subclasses and activities of proteins involved in reverse cholesterol transport in hypertensive obese children. Our objective was to determine low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subclasses distribution and activities of lecithin:cholesterol acyltransferase (LCAT) and cholesteryl ester transfer protein (CETP) in hypertensive and non-hypertensive obese children. METHODS A total of 40 hypertensive and 25 non-hypertensive obese children were enrolled. Lipoprotein subclasses were assessed by polyacrylamide gradient gel electrophoresis. LCAT and CETP activities were determined as a rate of formation and a rate of transfer of cholesteryl esters. RESULTS Despite of comparable values of serum lipid parameters, a shift toward smaller LDL and HDL subclasses was observed in hypertensive compared to normotensive obese children. Activities of LCAT were similar, but proatherogenic CETP activities were significantly higher in the hypertensive group (p = 0.036). LCAT/net CETP ratio inversely correlated with relative proportion of small, dense LDL particles (ρ = -0.423; p = 0.025) in the group with hypertension. CONCLUSIONS The results of our study demonstrated a tendency toward altered distribution of lipoprotein subclasses in favor of more proatherogenic particles in childhood hypertension. Also, hypertensive obese children had increased proatherogenic CETP activity.

Abstract
AIM High-quality national representative data on obesity in Romanian children are needed to shape public health policies. To provide a unified data landscape on national prevalence, trends and other factors associated with underweight, overweight, and obesity in Romanian children aged 6-19 years, across the last decade (2006-2015). METHODS Using a common protocol, we selected published and unpublished studies that measured Romanian children in schools between 2006 and 2015. Children's BMI was classified using the current WHO, IOTF, and CDC references. RESULTS 25,060 children from 8 Romanian counties were included in the analysis. The prevalence of underweight children was 5%/4.5%/8.5% (WHO/IOTF/CDC), while the prevalence of overweight (including obese) children was 28.3%/23%/23.2% (WHO/IOTF/CDC). The prevalence of overweight children did not change significantly over the last decade (chi-square test p = 0.6). Male gender (odds ratio (OR) 1.37; 95% CI 1.29-1.45, compared to female); prepubertal age (OR = 3.86; 95% CI 3.41-4.36,compared to postpubertal age), and urban environment (OR 1.12; 95% CI 1.01-1.26, compared to rural environment) had higher risk for overweight. CONCLUSION While the prevalence of underweight children was low, almost one in four children in Romania was overweight or obese (according to WHO criteria) between 2006 and 2015. This prevalence remained relatively stable over the last decade. Male gender, prepubertal age, and urban environment, were the most relevant risk factors associated with overweight status in Romanian children.

Abstract
BACKGROUND Alanine aminotransferase (ALT) has been one of the most useful biomarkers reflecting liver damage. Some studies have proposed that serum ALT levels, even those within the conventional normal range, are associated with metabolic syndrome and fatty liver. AIMS We examined the correlation between ALT levels and insulin resistance (IR) and ALT cutoff value for high IR status in Korean adolescents. METHODS A total of 886 subjects (461 boys and 425 girls) who participated in the 2009-2010 Korea National Health and Nutrition Examination Survey were included in this study. Multivariable adjusted logistic regression analyses were used to examine the odds ratios and 95 % confidence intervals (CIs) of the prevalence of the highest quartile of the homeostasis model assessment of IR (HOMA-IR) according to the ALT quartile. The cutoff value of ALT for the highest HOMA-IR quartile (Q4) were obtained using receiver operating characteristic curve analysis. RESULTS The mean ALT value increased as the number of metabolic syndrome components increased, but in only boys (p for trend <0.001), while the IR quartile increased in both boys and girls (all p for trends <0.001). The prevalence of IR (Q4) was only increased in ALT (Q4) in boys after the adjustment for age, body mass index, and waist circumference (OR 2.49; 95 % CI 1.05-5.91; p for trend = 0.017). The cutoff values were 17.0 IU/L in boys and 11.0 IU/L in girls. CONCLUSIONS The highest ALT quartile was associated with an increased prevalence of the highest quartile of IR in boys but not in girls.

Abstract
BACKGROUND Fetuin A is an inhibitor of insulin action and have been found to be related with subcutaneous lipid accumulation and insulin resistance. The relation of cardiac lipid accumulation, fetuin A and insulin resistance parameters in obese children is not well-known. The aim of the study was to evaluate the relation of serum fetuin A levels with subcutaneous and cardiac lipid accumulation, and insulin resistance parameters in Turkish obese children. METHODS Serum fetuin A levels, cardiac and subcutaneous lipid accumulation parameters of 42 obese (10.9±2.3 years, 19 female) and 40 control group subjects (11.2±2.7) were compared. Cardiac lipid accumulation measured by subepicardial adipose tissue thickness. Insulin resistance was assessed using homeostasis model assessment (HOMA-IR) index. RESULTS There were significant correlations serum fetuin A levels with BMI-SDS, circumferences of waist, hip and midarm, SATT and HOMA-IR (r=0.362, p=0.018, r=0.728, p=0.001, r=0.662, p=0.0001, r=0.713, p=0.0001, r=0.477, p=0.001, and r=0.330, p=0.038 as, respectively). CONCLUSIONS Fetuin A was correlated well with cardiac and subcutaneous lipid accumulation, insulin resistance parameters, which may be related with early pathogenetic mechanisms of metabolic obesity complications in children.

Abstract
The use of blood pressure measurements have become a routine part of physical exam for the evacuation of cardiovascular health adults and, more recently, children. The most widely used definition of hypertension is delineate as greater than 90 % BP according to age, sex, and height by the National High Blood Pressure Education Program. Current research suggests that pediatric hypertension is influenced by multitude of factors including birth weight, maturity during birth, heredity, and diet leading to primary hypertension. Factors influencing secondary hypertension include renal abnormalities, coarctation of the aorta, medications, neoplasm, etc. The treatment for pediatric hypertension is carried out with diet and exercise as the first line of defense. Only under non-compliance with diet and exercise is pharmaceutical intervention appropriate. This paper outlines a concise summary of the current understanding and research for scientists, clinicians, as well as for the general population to better understand pediatric hypertension.

Abstract
Background Childhood obesity is associated with chronic low-grade inflammation considered as a precursor to metabolic disease; however, the underlying mechanisms for this remain unclear. Studies in adults have implicated gut derived gram-negative bacterial fragments known as lipopolysaccharide or endotoxin, activating the inflammatory response, whilst the importance in childhood obesity is unclear. The aim of this research is to understand the relationship between circulating endotoxin in childhood obesity, and its’ association with inflammatory and cardiovascular (CV) injury biomarkers. Methods Fasted blood was obtained from children with varying degrees of obesity (age: 13.9 ± 2.3Yr; BMI: 35.1 ± 5.2 Kg/m2; n = 60). Multiplex CVD biomarker immunoassays were used to determine systemic levels of inflammatory and vascular injury biomarkers, such as tumour necrosis factor-α (TNF-α), interleukin (IL-) 1β, 6, 8 and 10, plasminogen activator inhibitor-1 (PAI-1), soluble intercellular adhesion molecule type-1 (sICAM-1), matrix metalloproteinase-9 (MMP-9), myeloperoxidase (MPO) and vascular endothelial growth factor (VEGF) as well as endotoxin levels. Results Endotoxin levels demonstrated a significant and positive correlation with the markers for inflammation, vascular injury and atherogenesis (TNF-α: r2 = 0.077, p < 0.05; PAI-1: r2 = 0.215, p < 0.01; sICAM-1: r2 = 0.159, p < 0.01; MMP-9: r2 = 0.159, p < 0.01; MPO: r2 = 0.07, p < 0.05; VEGF: r2 = 0.161, p < 0.01). Males demonstrated significantly higher circulating endotoxin than females (Males: 9.63 ± 5.34 EU/ml; p = 0.004; Females: 5.56 ± 4.06 EU/ml; n = 60) in these BMI and age-matched cohorts. Conclusion The present study demonstrates for the first time a significant association between circulating endotoxin and biomarkers of metabolic risk in children as young as 11 years. Thus, endotoxin-mediated sub-clinical inflammation during childhood obesity may be a key contributor to T2DM and CVD development later in life.

Alterations in Hepatic FGF21, Co-Regulated Genes, and Upstream Metabolic Genes in Response to Nutrition, Ketosis and Inflammation in Peripartal Holstein Cows. PLoS One 2015; 10:e0139963.

Abstract
In rodents, fibroblast growth factor 21 (FGF21) has emerged as a key metabolic regulator produced by liver. To gather preliminary data on the potential importance of FGF1, co-regulated genes, and upstream metabolic genes, we examined the hepatic mRNA expression in response to nutrition and inflammation in dairy cows. In experiment 1, induction of ketosis through feed restriction on d 5 postpartum upregulated FGF21, its co-receptor KLB, and PPARA but only elicited a numerical increase in serum FGF21 concentration. In experiment 2, cows in control (CON) or receiving 50 g/d of L-carnitine (C50) from -14 through 21 d had increased FGF21, PPARA, and NFIL3 on d 10 compared with d 2 postpartum. In contrast, compared with CON and C50, 100 g/d L-carnitine (C100) resulted in lower FGF21, KLB, ANGPTL4, and ARNTL expression on d 10. In experiment 3, cows were fed during the dry period either a higher-energy (OVE; 1.62 Mcal/kg DM) or lower-energy (CON; 1.34 Mcal/kg DM) diet and received 0 (OVE:N, CON:N) or 200 μg of LPS (OVE:Y, CON:Y) into the mammary gland at d 7 postpartum. For FGF21 mRNA expression in CON, the LPS challenge (CON:Y) prevented a decrease in expression between d 7 and 14 postpartum such that cows in CON:N had a 4-fold lower expression on d 14 compared with d 7. The inflammatory stimulus induced by LPS in CON:Y resulted in upregulation of PPARA on d 14 to a similar level as cows in OVE:N. In OVE:Y, expression of PPARA was lower than CON:N on d 7 and remained unchanged on d 14. On d 7, LPS led to a 4-fold greater serum FGF21 only in OVE but not in CON cows. In fact, OVE:Y reached the same serum FGF21 concentration as CON:N, suggesting a carryover effect of dietary energy level on signaling mechanisms within liver. Overall, results indicate that nutrition, ketosis, and inflammation during the peripartal period can alter hepatic FGF21, co-regulated genes, and upstream metabolic genes to various extents. The functional outcome of these changes merits further study, and in particular the mechanisms regulating transcription in response to changes in energy balance and feed intake.

Abstract
Civilization diseases, including cardiovascular, are major health problems in current modern society. Numerous studies provided sufficient evidence that variety of risk factors are involved in cardiovascular diseases formation. Of the most important is the lifestyle that largely contributes to our health, up to 50 - 60%. Lifestyle includes all modifiable risk factors that together affect the development of these diseases. In our study we searched and evaluated the nutritional parameters and lifestyle of patients hospitalized in Cardiocentre Nitra. In order to obtain the necessary information we chose the questionnaire method. In our survey 194 patients were included, of which 155 were men (79.89%) and 39 (20.11%) women. These patients were hospitalized with acute myocardial infarction diagnosis. The vast majority of patients had overweight and obesity caused by improper eating habits. The high prevalence of overweight, BMI in the range 25 - 30 kg/m2, was also confirmed as statistically significant, p <0.05 (P=0.02). BMI over 25 kg/m2 was present in 85% of men and 80% of women. The consumption of selected food commodities with evidence of a positive or negative impact on the emergence of acute myocardial infarction was not statistically significant (p >0.05) when evaluating dietary habits. But we can confirm too frequent consumption of chicken at the expense of other types of meat and relatively frequent consumption of fish (once a week). We recorded the preference of semi-skimmed dairy products, but also high and inappropriate consumption of full-fat dairy products in men and women (37% and 17.8%, respectively). Daily intake of fruits and vegetables was in 85.9% of women and 64.7% of men. Everyday intake of bread and pastries was confirmed by 100% of respondents. Lifestyle was evaluated according to the presence of smoking, excessive alcohol consumption, and physical activity. Up to 60.5% of men and 26.4% of women admitted smoking, while 34.6% of men and 7.5% women ended up with the habit after myocardial infarction. The excessive alcohol consumption was not detected in the study group. Approximately 67% of men and 56% of women carry out an easier walking and moderate physical activity while taking into account their health status.
