Neck Circumference and Its Relation with Body Fat Percentage in Children 5-10 Years Old.

Neck circumference (NC) has been proposed as an indicator of upper trunk adiposity and a potential indicator of metabolic risk. The objective was to evaluate NC and its correlation with body fat percentage (BF%) and other indicators of adiposity in children with normal weight, overweight, and obesity. In a cross-sectional study, 112 children 5 to 10 years of age were included in the outpatient clinic from a public hospital. Measures of weight and height to calculate BMI (kg/m2), NC, mid-upper arm circumference, waist circumference, and tricipital skinfold thickness. Body composition measurements were performed using an electrical bioimpedance device (BIA). The relationship between anthropometric variables and BF% obtained by BIA was determined using Spearman correlation tests. Multivariate models were constructed with BF% as the dependent variable and anthropometric parameters as independent. In the entire group, there was a direct correlation between NC and BF% (r = 0.50, p < 0.001), but lost statistical significance in the case of normal weight. The relationship maintained its significance in subjects from the overweight and obesity groups. In multivariate models, BMI exhibited the highest correlation with BF%, followed by waist circumference and mid-upper arm circumference; for NC, the R2 value was 0.30 (p < 0.001). Neck circumference is useful in the screening of population groups with the advantage of not requiring any specialized instruments for its measurement other than a tape measure. BMI and waist circumference were the best indicators of general and central adiposity, respectively.

Serum Levels of Adipolin and Adiponectin and Their Correlation with Perinatal Outcomes in Gestational Diabetes Mellitus.

Objectives: This study aimed to investigate the serum level of adipolin and adiponectin in healthy pregnant women and pregnant women with gestational diabetes mellitus (GDM) during the second trimester, the prepartum period, and in the newborns of these patients. Methods: A total of 55 women diagnosed with GDM and 110 healthy pregnant women were included in this study. Pearson's and Spearman's correlation coefficients were calculated to determine the association of adipolin and adiponectin with anthropometric markers of obesity (body mass index (BMI), mid-upper arm circumference (MUAC), tricipital skinfold thickness (TST)), inflammation markers (neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP)), and maternal glucose homeostasis parameters (fasting glucose, insulin, C peptide, glycosylated hemoglobin A1c (HbA1c), Insulin Resistance-Homeostatic Model Assessment (IR HOMA)). Results: There were no statistical differences between the adipolin value in patients with GDM compared to healthy patients (p = 0.65 at diagnosis and p = 0.50 prepartum) and in newborns from mothers with GDM compared to healthy mothers (p = 0.24). Adipolin levels are significantly higher in patients with GDM who gave birth via cesarean section (p = 0.01). In patients with GDM, the adipolin level correlates positively with HgA1c in the prepartum period. We found a positive correlation between the maternal adipolin values at diagnosis and prepartum and neonatal adipolin (respectively: r = 0.556, p = 0.001; r = 0.332, p = 0.013). Adiponectin levels were significantly lower in patients with GDM at diagnosis and prepartum (p = 0.0009 and p = 0.02), but their levels increased prepartum (5267 ± 2114 ng/mL vs. 6312 ± 3150 ng/mL p = 0.0006). Newborns of mothers with GDM had lower adiponectin levels than newborns of healthy mothers (p < 0.0001). The maternal adiponectin value correlates negatively with maternal BMI, MUAC, and IR HOMA in both groups at diagnosis and prepartum. There were no differences between the groups in terms of cesarean rate (p > 0.99). The relative risk of occurrence of adverse events in patients with GDM compared to healthy ones was 2.15 (95% CI 1.416 to 3.182), and the odds ratio for macrosomia was 4.66 (95% CI 1.591 to 12.69). Conclusions: There was no difference in adipolin levels between mothers with GDM and healthy mothers during the second trimester and the prepartum period. Adipolin is known to enhance insulin sensitivity and reduce inflammation, but unlike adiponectin, it does not appear to contribute to the development of GDM.

Maternal diet quality and associations with body composition and diet quality of preschool children: A longitudinal study.

Nutrition, associated with nutritional status, influences the growth of children. This study aimed to identify the association between maternal diet quality and the diet and body composition of their children. This is a prospective longitudinal study with mother-child pairs. To assess diet quality, nutritional status, and socioeconomic data, two interviews in the children's first and third months of life (2011-2016) and one interview when children were of preschool age (2017-2019) were performed. Diet quality was assessed based on daily food consumption and frequency, considering: 1) food groups, based on the Brazilian food pyramid; 2) level of processing, according to the NOVA classification (unprocessed and/or minimally processed foods, processed foods and ultra-processed foods). One-way ANOVA with Tukey post hoc and Kruskal-Wallis with Dunn's post hoc tests were used to evaluate the influence of factors on children's diet quality. Pearson and Spearman's correlations were used to evaluate the relationship between maternal and children's diet quality, maternal schooling level, and child age. Along with the nutritional assessment of children, multiple linear regression models assessed the impact of covariables on maternal and children's diet quality. Eighty-three mother-child pairs participated in this study. The more frequent the maternal consumption of unprocessed and/or minimally processed foods, the higher the consumption of these foods by children (r = +0.30; p = 0.006) and the lower their subscapular skinfold (SSF) thickness (p = 0.011; β = -0.278). On the other hand, the higher the maternal consumption of ultra-processed foods, the higher the children's tricipital skinfold (TSF) thickness (p = 0.010; β = +0.274) and SSF (p = 0.043; β = +0.222). Maternal diet quality was associated with the diet and body composition of children.

Association between Anthropometry and Gestational Diabetes Mellitus

Introduction: The predictive value of various anthropometric indicators for identifying benefits or risksfor maternal health outcomes of pregnancy is discussed around the globe. Anthropometric measurements can be a cost effective, efficient method of screening for gestational diabetes mellitus (GDM) especially, in developing countries with low-cost health care settings. Objectives: To determine a relationship between anthropometric measurements and GDM and to assess the importance/suitability of an anthropometric measurement in predicting GDM. Methods: A correlational study with the evaluation of diagnostic test accuracy was conducted among 48 pregnant women at period of amenorrhoea (POA) of 26 - 34 weeks of gestation. The obstetrics ward and the antenatal clinic of Peradeniya teaching hospital was the study setting. Systematic random sampling technique was used for participant selection. Singleton pregnancies with Body Mass Index (BMI) less than 30.0 kg/m2 were included. Women with pre-existing diabetes and medical disorders were excluded. Mid arm circumference (MAC), tricipital skin fold thickness (TSFT), bicipital skin fold thickness (BSFT) were measured according to the National Health and Nutrition Examination Survey (NHANES) anthropometry manual. An interviewer-administered questionnaire was applied to collect the data. Data was evaluated in accordance with the objectives by using SPSS version 25. Results: Mean age of the participants was 29.67 years (SD = 4.76 years). Mean height and weight of the study participants were 154.93 cm and 67.45 kg respectively. Mean BMI value was recorded as 28.13 kgm2. Mean mid arm circumference was 9.43 cm. According to the multivariate analysis done by using logistic regression, calculated TSFT and BSFT values were independently associated with GDM in the population. Successful prediction can be achieved by using the BMI and the body weight (AUC 0.5). 24.8 kg/m2 is taken as the best cut off value to predict GDM (Sn = 79.2; Sp = 29.2). Best cut off value for body weight appears as 60 kg (Sn = 79.2; Sp = 32.3) and the best cut off value for height is 150 cm (Sn = 80.0; Sp = 25.0). When the predictive variables are compared with each other, highest predictive ability was recorded by the body mass index (AUC = 0.632). Predictability of TFT and BSFT appeared significant. 27.0 cm can be considered as the most accurate cut off value of MAC (Sn = 80; Sp = 30). Best cut off values for BSFT and TSFT were 22 mm (Sn = 80; Sp = 60) and 10.5 mm (Sn = 83.3; Sp <span styl

Combined Dietary Education and High-Intensity Interval Resistance Training Improve Health Outcomes in Patients with Coronary Artery Disease.

Background: Reducing cardiovascular risk through lifestyle changes that include a heart-healthy diet and regular exercise is recommended in the rehabilitation of patients with coronary artery disease (CAD). We pilot-tested the effectiveness of a dietary-education and high-intensity interval resistance training (DE–HIIRT) program on healthy food choices and associated anthropometric variables in patients with established CAD. Methods: A total of 22 participants, aged 60.0 ± 7.2 years, were enrolled in the study. Over 3 months, under the guidance and supervision of a physiotherapist, participants performed the resistance exercises 2×/week in a group setting (cohort of 11). Participants additionally attended three sessions of dietary education led by a dietician. Participants demonstrated their knowledge and understanding of dietary education by picking heart-healthy foods by reading food labels. Outcomes included change in diet (measured using the tricipital skinfold thickness Mediterranean Diet Adherence questionnaire (MEDAS-14) and the Food Consumption Frequency Questionnaire (FCFQ)) and anthropometric measurements (body composition, body circumference, and tricipital skinfold thickness). A paired t-test was performed to analyze the differences between the baseline and post-intervention results. Results: Participants significantly increased their consumption of vegetables (p = 0.04) and lowered their consumption of sweet snacks (p = 0.007), pastries (p = 0.02), and processed food (p = 0.05). Significant improvements in body mass index (p = 0.001), waist circumference (p = 0.0001), hip circumference (p = 0.04), and body fat (p = 0.0001) were also achieved. Conclusion: Making lifestyle changes that include both diet and exercise is essential in the management of CAD. The HIIRT program combined with dietary changes shows promise in achieving weight-loss goals in this population and needs to be further investigated with appropriate study designs.

Effects of a period without mandatory physical training on maximum oxygen uptake and anthropometric parameters in naval cadets.

The effects of a period without physical training on the civilian population are well established. However, no studies show the effects of a period without mandatory physical training on maximum oxygen uptake (VO2 max) and anthropometric parameters in naval cadets. This study aimed to investigate changes in VO2 max and anthropometric parameters after 12 weeks without mandatory physical training in naval cadets. The sample was 38 healthy and physically active naval cadets. The measured variables, including VO2 max and anthropometric parameters, were evaluated through the 12-minute race test (12MRT) and the somatotype. Both variables had a separation of 12 weeks without mandatory physical training. A t-test for related samples was used to evidence changes between the test and post-test; effect size was calculated through Cohen’s d-test. Distance in 12MRT and VO2 max showed significant decreases at the end of 12 weeks without mandatory physical training (p < 0.001). Likewise, the tricipital skinfold thickness and the endomorphic component showed significant increases (p < 0.05). 12 weeks without mandatory physical training significantly reduces the VO2 max in naval cadets. Simultaneously, the same period without physical training increases both the tricipital skinfold thickness and the endomorphic component in this population.

Correlations among neck circumference and anthropometric indicators to estimate body adiposity in people living with HIV.

INTRODUCTION: Neck circumference (NC) and anthropometric data of people living with HIV (PLWH) are correlated. METHODS: Socioeconomic, NC, body mass index (BMI), tricipital skinfold thickness (TSF), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), waist-hip ratio (WHR), waist-to-height ratio (WHtR), waist circumference (WC), and hip circumference (HC) data of 72 PLWH were correlated. RESULTS Higher adiposity was observed in NC (40.3% [n=29]) and WC (31.9% [n=23]). Correlations between NC/BMI, NC/WC, NC/HC, NC/MAC, NC/MAMC, and NC/WHtR were significant. Increased NC (40.3%[n=29]) and WC (31.9 [n=23]) were associated with higher cardiometabolic risk. CONCLUSIONS: NC correlations are adequate for estimating cardiometabolic risk.

Relationships between excessive gestational weight gain and energy and macronutrient intake in pregnant women.

ObjectiveThis study aimed to compare energy and macronutrient intake, birth weight, and anthropometric parameters (mid-upper arm circumference or tricipital skin-fold thickness) between women who had adequate and excessive gestational weight gain (GWG) during pregnancy.MethodsWe studied 115 pregnant women and divided them according to GWG into two groups: adequate GWG (n = 49) and excessive GWG (n = 66). We assessed the medical history, clinical examinations, and dietary habits through a detailed 7-day dietary recall using myfitnesspal software.ResultsWeight, body mass index, mid-upper arm circumference, and tricipital skin-fold thickness were significantly higher at the time of delivery in women with excessive GWG compared with those with adequate GWG. A lipid-based diet was a risk factor for excessive GWG (relative risk: 1.488, 95% confidence interval: 1.112–1.991), whereas a protein-based diet was a protective factor (relative risk: 0.6723, 95% confidence interval: 0.4431–1.020). We found no significant relationship between a carbohydrate-based diet and GWG. The total energy intake was significantly higher in the excessive GWG group than in the adequate GWG group.ConclusionsMainly a lipid-based diet in pregnant women might represent a risk factor for excessive GWG. However, a protein-based diet is a protective factor for excessive GWG.

Blood Pressure, Heart Rate Variability, and Adiposity in Caribbean Pre-pubertal Children.

Childhood obesity prevalence has increased over the last 30 years. The Heart Rate Variability (HRV) studies performed in adults suggest a possible relation between abnormal autonomic regulation and hypertension in the situation of overweight or obesity.Objective: The aims of this study were to explore the early relationships between adiposity and blood pressure and HRV in pre-pubertal children.Methods: Data were collected during the medical examination of the follow-up at 7 years of the TIMOUN mother-child cohort in Guadeloupe. Body Mass Index z-score (zBMI), sum of tricipital and subscapular skinfold thickness, percentage of fat mass, and Waist-to-Height Ratio were measured. A global corpulence score was computed using a Principal Component Analysis (PCA). Systolic Blood Pressure (SBP) and HRV parameters (cardiac holter monitoring) were collected under 2 conditions (calm and tachycardial period). Relations between HRV, SBP, each adiposity indicator and the corpulence score were studied with restricted cubic splines models, and linear regression models. The age at adiposity rebound (AR) was estimated from the individual growth curves.Results: 575 children were included in the SBP study (mean age: 7.7 years, from 85 to 99 months). SBP was linearly correlated with the corpulence score and the zBMI. An increase of 1 in the zBMI was associated with an increase of 2.3 (±0.28) mmHg in SBP. The effect-size of zBMI on SBP was higher in children with early age at AR. Compared to children with normal BMI, children with a zBMI <™2SD had their RMSSD, SDNN, LF and HF indicators in tachycardial conditions significantly reduced by −30, −21, −37, and −48%, respectively. In boys with a zBMI >2SD, we observed a global increase in all HRV parameters (under tachycardial conditions), particularly the LF [β = 0.43 (±0.18)].Conclusion: In pre-pubertal period a positive correlation between adiposity excess and SBP was observed with significant changes of HRV in boys, arguing for an early abnormal autonomic regulation and for early preventive intervention in the infancy period, particularly in case of overweight or obesity. Thinness was associated with a reduction in almost all the HRV parameters studied, when compared to normal corpulence, suggesting a decrease in autonomic influence.

The metabolic hormone FGF21 is associated with endothelial dysfunction in hemodialysis patients

Finding new, reliable biomarkers of cardiovascular risk in hemodialysis (HD) patients is of utmost importance. Fibroblast growth factor 21 (FGF21) has been recently associated with atherosclerosis in the general population. The relationship between markedly elevated FGF21 levels in HD patients and endothelial dysfunction is unknown. The aim of the study was to assess the determinants of FGF21, the correlation between FGF21 and tumor necrosis factor TNF-like weak inducer of apoptosis (sTWEAK) and the correlation between FGF21 and endothelial dysfunction in HD patients. A cross-sectional observational study was conducted in 70 HD patients (mean age 59.9±12.5years, 14.3% diabetes mellitus, 57.1% male) from Nefromed Dialysis Center Cluj. We registered clinical and biological data, and serum FGF21 levels were measured by ELISA. Endothelial function was evaluated by brachial flow-mediated dilation (FMD). An analysis based on stratification of FGF21 values into quartiles was performed. FGF21 levels were directly correlated with sTWEAK, tricipital skinfold thickness (TST), systolic blood pressure (SBP), total cholesterol and triglycerides. In multivariate linear analysis, only sTWEAK and SBP remained significantly associated with FGF21. FGF21 values in the inferior quartile were directly correlated with HDL-cholesterol, while FGF21 values in the superior quartile were directly correlated with SBP, pulse pressure and sTWEAK. FMD was significantly higher in the inferior quartile as compared to the superior quartile. High FGF21 values in our patients are correlated with atherosclerosis risk factors: hypercholesterolemia, hypertriglyceridemia, hypertension, increased TST and increased levels of sTWEAK. Endothelial dysfunction is associated with high FGF21 in HD patients.

Assessment of Body Composition in a Group of Pediatric Patients With Cancer: A Single Romanian Center Experience

Cancer patients are particularly susceptible to nutritional depletion. From March 2014 to December 2015, we assessed 146 patients consecutively hospitalized in a tertiary emergency pediatric hospital. The patients were divided into 2 groups: group I, patients with cancer (43 patients), and group II, the control group consisting of 103 age-matched and sex-matched healthy patients. The anthropometric parameters (weight-W, height-H, body mass index [BMI], middle upper arm circumference [MUAC], tricipital skinfold thickness [TST]) and biochemical parameters (proteins, albumin) were comparatively evaluated. Fat mass (FM, kg and %), fat-free mass (FFM, kg), muscle mass (MM, kg), and total body water (TBW, %) were measured in both groups using Tanita BC 420 S MA Analyzer. Anthropometric and biochemical parameters in group I were significantly different from those in group II for weight, height, BMI, MUAC, TST, protein, and albumin (P<0.05). In the study group, FM was much lower compared with controls 16.9% (3.4% to 33.3%) versus 20.3% (6.6% to 38.4%); (P=0.001), and TBW was much higher 60.8% (48.8% to 70.6%) versus 58.5% (45.2% to 68.6%) (P=0.004). FFM and MM were not statistically different in the 2 groups. The results highlight the complex changes of nutritional status in pediatric patients with cancer.

Valoración de la composición corporal y su influencia pronóstica en insuficiencia cardiaca crónica. Más allá de la «paradoja de la obesidad»

It is unknown the influence of body composition in the inverse relationship of mortality with overweight and obesity in heart failure patients. 234 patients with chronic heart failure were evaluated. Body mass index, tricipital skinfold thickness, brachial muscle circumference and body fat percentage determined by bioelectrical impedance analysis were measured. The influence of previous anthropometric variables on total mortality was analyzed. Mean follow-up was 21±10.7 months. We observed an inverse relationship of total mortality with body mass index (hazard ratio=0.91, 95% confidence interval, 0.87-0.96; P<.001), with body fat estimated by the tricipital skinfold thickness (hazard ratio=0.95, 95% confidence interval, 0.92-0.99; P=.013) and the fat percentage obtained by bioelectrical impedance analysis (hazard ratio=0.96; 95% confidence interval, 0.93-0.99; P=.007) and with muscle mass estimated by the brachial muscle circumference (hazard ratio=0.87; 95% confidence interval,0.81-0.94; P=.001). Only brachial muscle circumference maintained its prognostic significance in multivariate analysis that included different anthropometric measurements (hazard ratio=0.88, 95% confidence interval 0.77-0.99; P=.035). Finally we found a positive linear correlation between the values of body mass index with tricipital skinfold thickness, fat percentage and brachial muscle circumference. The muscle mass of patients with heart failure, estimated by the brachial muscle circumference, is associated inversely with overall mortality. The correlation between values of brachial muscle circumference with the body mass index would explain the "obesity paradox" observed.

The role of TGF-β1 869 T > C and PPAR γ2 34 C > G polymorphisms, fat mass, and anthropometric characteristics in predicting childhood obesity at birth: A cross-sectional study according the parental characteristics and newborn's risk for child obesity (the newborns obesity's risk) NOR study.

This study proposed to establish a correlation between the risk score for child obesity and anthropometric, genetic, and bioimpedance characteristics in mothers and newborns, and to assess the discriminant ability for anthropometric parameters to classify over-fatness (defined by bioimpedance body fatness %) in pregnant women.We performed a cross-sectional study on 388 couples (mother and father) and their newborns admitted in a Tertiary Hospital from Romania. The measured parameters for mothers and their newborns were risk percentage for child obesity, anthropometric characteristics (mid-upper arm circumference [MUAC], tricipital skinfold thickness [TST] of mother and newborn), genetic polymorphisms (human peroxisome proliferator-activated receptor γ [PPARγ2] 34 C > G and transforming growth factor-beta 1 [TGF-β1] 869 T > C gene polymorphisms in both mothers and newborns), and mother's bioimpedance characteristics (fat mass [FM] %).The obesity risk score according to standard predictable Northern Finland Birth Cohort equation was in our study 4.07%. We found a monotone positive significant correlation between the newborn's risk of childhood obesity and the mother's TST (P = 0.01), as well as a tendency toward statistical significance concerning correlation with mother's MUAC (P = 0.053), without any correlations with the mothers’ bioimpedance parameters and also a positive correlation between the newborn's risk of childhood obesity and the newborn's anthropometrical characteristics like body mass index (BMI), MUAC, and TST (P < 0.001). We observed that the calculated newborn's risk percentage for child obesity was greater for the variant allele of the TGF-β1 869 T > C polymorphism and also for the wild-type C allele of the PPARγ2 34 C > G gene polymorphism. Our study indicated that the best predictors for over-fatness are BMI and MUAC (P = 0.01 < 0.02 and P = 0.019 < 0.02, respectively).

Perfil Nutricional de Pacientes HIV Positivo do Município de Apucarana (PR)

Conhecer o perfil nutricional dos pacientes com HIV é o primeiro passo para uma nutrição adequada e um tratamento bem sucedido, garantindo ao paciente uma melhora na qualidade de vida. Sendo assim, o estudo tem por objetivo avaliar o perfil nutricional do paciente portador do Vírus da Imunodeficiência Humana no município de Apucarana(PR). A coleta de dados foi realizada por meio de peso, estatura, índice de massa corporal, circunferência da cintura, circunferência do braço, dobra cutânea tricipital e circunferência muscular do braço. Além disso, foram aplicados questionário de frequência alimentar e questionário sobre histórico da doença. Os resultados apontam uma mudança no perfil nutricional dos pacientes, onde 45,5% apresentam sobrepeso, seguidos de indivíduos eutróficos. Essa mudança está relacionada ao uso de medicações antirretrovirais, pois estas possuem como efeito colateral a redistribuição de peso corpóreo.

FTO rs 9939609 SNP Is Associated With Adiponectin and Leptin Levels and the Risk of Obesity in a Cohort of Romanian Children Population.

Obesity is a disorder with increasing frequency in children and adolescents, directly linked with various diseases. Variants in the FTO (fat mass and obesity-related) gene have been associated with body mass index and waist and hip circumferences in widespread populations.The aim of this case-control study was to assess if there is any association between FTO gene variants rs9939609, respectively, rs17817449 with anthropometric and metabolic biomarkers (fasting glucose, TC, HDL-cholesterol, LDL-cholesterol, triglycerides) and adipokines (adiponectin and leptin), in Romanian obese children.A total of 387 children, 201 obese and 186 nonobese individuals, were included in this prospective study. Genotyping of the FTO gene polymorphisms for all subjects was performed using the restriction fragment length polymorphism (PCR–RFLP) method.Significant associations were found between FTO rs9939609 single nucleotide polymorphism (SNP) and obesity. AA genotype carriers have a 2.02 times higher risk for obesity compared with AT+TT genotype carriers. Risk allele carriers of rs17817449 SNP had somewhat higher values of weight, body mass index, waist and hip circumference, total cholesterol, triglycerides, adiponectin, and fasting glucose.This study revealed the genetic association between rs9939609 SNP of FTO and obesity in a Romanian population, and to the authors’ knowledge, this is the first study to investigate this association in a Romanian population. This study also established that combined variant genotypes (AA/GG) of FTO rs9939609 /rs17817449 are strongly associated with several measures of adiposity (weight, BMI-SD, mid-upper arm circumference, tricipital skinfold thicknesses) and are also associated with total cholesterol, triglyceride, and LDL-cholesterol levels.

Evaluation of Protein-Energy Wasting and Inflammation on Patients Undergoing Continuous Ambulatory Peritoneal Dialysis and its Correlations.

Background:Protein-energy wasting (PEW) and heightened inflammation are prevalent in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and is a strong risk factor for morbidity and mortality in these patients. Evaluation of PEW, prevalence of inflammation as well as interrelationship between various nutritional indices and inflammation has not been studied in much detail in patients undergoing CAPD.Objectives:This study was conducted to evaluate the interrelationship between PEW and inflammation in patients undergoing CAPD.Patients and Methods:Sixty-three patients undergoing CAPD (M = 28, F = 35) were assessed with regard to their nutritional status and inflammation after a minimum of 3 months CAPD initiation. Nutritional status was assessed by dietary diary, anthropometry, subjective global assessment, and multifrequency bioelectrical impedance analysis (BIA). In addition, their serum albumin, prealbumin, transferrin, and cholesterol level were measured. Also, inflammation in these patients was assessed by High-Sensitivity C-Reactive Protein (hs-CRP > 3 mg/L) and Interleukin-6 (IL-6 > 2 µg/mL). Later on, diagnosis of malnutrition was made based on different methods. Correlation between inflammation and various nutritional assessment indices were analyzed statistically.Results:Mean (SD) age of the patients was 57.6 (11.6) years. The average (SD) calorie and protein intake per day were 25.5 (4.6) kcal and 0.81 (0.2) mg, respectively. The mean and standard deviation of anthropometry variables of body mass index (BMI), mid-arm circumference (MAC), tricipital skin-fold thickness (TST), mid-arm muscle circumference (MAMC), and corrected mid-arm muscle area (cMAMA) were 23.7 ± 5 kg/m2, 26.3 ± 4.5 cm, 1.624 ± 0.4 cm, 25.6 ± 4.5 cm, and 45.7 ± 19.7 cm2, respectively. The mean values of serum protein, albumin, prealbumin, transferrin, cholesterol, triglyceride, hs-CRP, and IL-6 were 5.9 g/dL, 3.0 g/dL, 21.11 mg/dL, 130.6 mg/dL, 155.9 mg/dL, 136.1 mg/dL, 8.8 ± 7.6 mg/L, and 8.4 ± 12.2 µg/dL, respectively. Based on subjective global assessment (SGA); 11.63 (17.4%), 34.63 (54%), and 18.65 (28.6%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. According to serum albumin level; 13.63 (21%), 39.63 (62%), and 11.63 (17%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. Finally, based on BMI; 33.63 (52%), 23.63 (37%), and 7.63 (11%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. About 76.1% and 9.5% of patients undergoing CAPD were malnourished based on lean tissue index (LTI) and fat tissue index (FTI), respectively. Based on hs-CRP and IL-6 findings, 70% (44/63) and 71.8% (45/63) of patients undergoing CAPD had high inflammation, respectively. High sensitive C-reactive protein correlated negatively (significantly) with serum albumin, prealbumin, and transferrin. Interleukin -6 correlated negatively (significantly) with MAC; MAMA; serum albumin, cholesterol, and transferrin. There was significant positive correlation between hs-CRP and IL-6. There is statistically significant difference in total protein intake (g/d), protein intake (g/kg/d), serum protein (g/dL), albumin (g/dL), transferrin (mg/dL), and cholesterol (mg/dL) between patients with and without inflammation.Conclusions:Protein-energy wasting (80% - 85%) by various methods and inflammation (70%) was very prevalent among patients undergoing CAPD. Inflammatory markers show significant negative correlation with anthropometry and serological markers. Inflammatory markers are suggested to be included in the regular assessment of patients undergoing CAPD, for the better management of protein-energy wasting.

The association of high sCD163/sTWEAK ratio with cardiovascular disease in hemodialysis patients.

Cardiovascular disease (CVD) is the most common cause of death in hemodialysis (HD) patients. Transmembrane proteins that circulate as soluble form such as tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) and CD163 have been proposed in previous studies as CVD biomarkers in chronic kidney disease patients. In HD patients, since studies are scarce, the role of these proteins is not completely understood. We tested the hypothesis that sTWEAK, sCD163 or sCD163/sTWEAK ratio could be associated with cardiovascular disease in HD patients. We recorded current clinical and biological data, and we measured sTWEAK and sCD163 serum levels by ELISA in 70 hemodialysis patients. Univariate analysis and multivariate (logistic regression) analysis were used to identify the relation between sTWEAK, sCD163 and sCD163/sTWEAK ratio and CVD. In univariate analysis, CVD in HD patients is associated with higher sCD163/sTWEAK ratio (p = 0.04), sCD163 (p = 0.07), CRP (p = 0.04), age (p = 0.07), smoking (p = 0.09) and vascular calcifications (p = 0.10). In multivariate analysis, only logarithm of sCD163/sTWEAK ratio (p = 0.04) and smoking (p = 0.03) was significantly associated with CVD. The levels of these molecules and their ratio were correlated with atherosclerosis risk factors: diabetes mellitus, high fasting glucose, tricipital skinfold thickness and CRP as well as (for sCD163/sTWEAK) intravenous iron therapy. Cardiovascular disease is associated with increased sCD163/sTWEAK ratio. To our knowledge, this is the first report about this relationship in HD patients.

Polymorphism in miR-31 and miR-584 binding site in the angiotensinogen gene differentially influences body fat distribution in both sexes.

Angiotensinogen (AGT), its active fragments and microRNA-31 (miR-31) play an important role in adipocyte differentiation. AGT contains a miR-31 polymorphic binding site. We hypothesize that the rs7079 polymorphism in the miR-31/584 binding site of the AGT gene could influence body fat distribution. A total of 751 subjects (195 men, 556 women) were enrolled in the study. The rs7079 genotypes were determined by qRT-PCR. Anthropometric measurements were taken on all subjects, who were subsequently divided into two groups: obese (>30kgm(-2)) and non-obese (<30kgm(-2)). Linear regression models were created to determine the contributions of sex, obesity status and rs7079 to all measured parameters. Adding the rs7079 genotype significantly contributed to the linear regression model for waist circumference (p=0.013), hip circumference (p=0.018) and supraspinal skin-fold thickness (p=1×10(-3)). Differences between sexes and between the obese and non-obese groups were observed. Waist circumference was lower in men carrying the A allele (p=0.022); hip circumference was higher only in obese women carrying the A allele (p=0.015). While men carrying the A allele had lower supraspinal skin-fold thickness (p=0.022), this parameter was found to be higher in A allele carrying women (p=3×10(-3)). The higher total sum of skin-fold thickness in A allele carrying women was restricted to obese individuals (p=0.028). The presence of the A allele was associated with both lower tricipital skin-fold thickness in non-obese women (p=0.023) and a trend of higher thickness in non-obese men (p=0.065). Significant associations of rs7079 in the AGT gene and body fat distribution were observed. The distribution followed opposing patterns in both sexes.

Angiotensin-converting enzyme gene insertion/deletion polymorphism in nutritional disorders in children.

The aim of this study was to establish the role of angiotensin-converting enzyme gene insertion/deletion (ACE I/D) polymorphism in determining obesity or undernutrition in a child population in Romania. We assessed 293 consecutively hospitalized patients in a tertiary emergency pediatric hospital. The patients were divided, according to body mass index (BMI), into three groups: group I, the control group consisting of 126 children, group II patients with undernutrition (85 patients) and group III patients with obesity (82 patients). ACE I/D polymorphisms were performed in all three patient groups, as well as the measuring of anthropometric parameters [middle upper arm circumference (MUAC), tricipital skinfold thickness (TST)]. All patients also underwent paraclinical evaluations (protein and albumin). The cutoffs criteria for moderate undernutrition were: BMI between -2.0 SD and -3.0 SD, severe undernutrition: BMI <-3.0 SD, moderate obesity: BMI between +2.0 SD and +3.0 SD and severe obesity: BMI >+3.0 SD. We observed that DD genotype (64.7%) was prevalent in the moderate undernutrition group, while ID (35.3%) and II genotypes were higher in the subgroup of severe undernutrition, with significant correlations in DD and ID genotype groups between BMI and MUAC, protein and albumin (p < 0.0001). In the obese group, we observed significant correlations in DD genotype, between BMI and MUAC (p = 0.0014) and TST, and for II genotype, between BMI and TST (p = 0.0071). II genotype was associated with severe obesity, while D allele carriers were associated with moderate undernutrition and moderate obesity. BMI, MUAC, TST and serum protein levels are correlated with D allele carriers of ACE genes in children with moderate undernutrition and moderate obesity, whereas II genotype is an unfavorable prognostic factor corresponding to severe obesity and severe undernutrition.

IL-6 572 C/G, 190 C/T, and 174 G/C gene polymorphisms in children's malnutrition.

The aim of the present study was to establish the correlations between the polymorphisms of the genes interleukin-6 (IL-6) 572, 190, and 174 in children's malnutrition. We assessed 283 hospitalized children and divided them into 2 groups: group I (control) included 110 patients with normal nutritional status, median (range) age 10.90 (1-18) years; and group II consisted of 173 malnourished patients, median (range) age 10.70 (1-18) years. The 2 groups underwent IL-6 572 cytosine allele (C)/guanine allele (G), 190 C/thymine allele (T), and 174 G/C polymorphism testing, measurement of anthropometric indicators (mid-upper arm circumference and tricipital skinfold thickness [TST]), and paraclinical evaluation (protein, albumin). We observed that the GG and CG genotypes were more frequent in malnourished children for the IL-6 174 gene (P = 0.0001), whereas the CT heterozygous genotype was more frequent in the malnourished group for the IL-6 190 gene (P = 0.003). Body mass index (BMI), middle upper arm circumference (MUAC), TST, and low serum albumin levels correlated with the GG and CG genotypes of the IL-6 572 and IL-6 174 genes, and with the CT genotype of the IL-6 190 gene, in children with malnutrition, whereas the IL-6 190 TT genotype was a protective factor for malnutrition (P = 0.0001). Malnutrition is more frequently associated in children with IL-6 174 G allele carriers (GG and CG genotypes), whereas IL-6 190 TT genotype has a protective function. In malnourished children, the IL-6 572/190/174 GG/CT/CG, GG/CT/GG, GG/CC/GG, and GG/CC/CG combined genotypes are more frequent.
