Genetic polymorphisms in the angiotensin converting enzyme, actinin 3 and paraoxonase 1 genes in women with diabetes and hypertension

ABSTRACT Objective: To study associations between polymorphisms in the angiotensin converting enzyme (ACE I/D), actinin 3 (ACTN3 R577X) and paraoxonase 1 (PON1 T(-107)C) genes and chronic diseases (diabetes and hypertension) in women. Materials and methods: Genomic DNA was extracted from saliva samples of 78 women between 18 and 59 years old used for genetic polymorphism screening. Biochemical data were collected from the medical records in Basic Health Units from Southern Brazil. Questionnaires about food consumption, physical activity level and socioeconomic status were applied. Results: The XX genotype of ACTN3 was associated with low HDL levels and high triglycerides, total cholesterol and glucose levels. Additionally, high triglycerides and LDL levels were observed in carriers of the TT genotype of PON1, and lower total cholesterol levels were associated to the CC genotype. As expected, women with diabetes/hypertense had increased body weight, BMI (p = 0.02), waist circumference (p = 0.01), body fat percentage, blood pressure (p = 0.02), cholesterol, triglycerides (p = 0.02), and blood glucose (p = 0.01), when compared to the control group. Conclusion: Both ACTN3 R577X and PON1 T(-107)C polymorphisms are associated with nutritional status and blood glucose and lipid levels in women with diabetes/hypertense. These results contribute to genetic knowledge about predisposition to obesity-related diseases.

Evaluation of thyroid function and metabolic parameters in obese and overweight children: A prospective case-control study / Evaluación de la función tiroidea y los parámetros metabólicos en niños obesos y con sobrepeso: Un estudio prospectivo de casos y controles

Abstract Obesity is considered an important global public health challenge, and its prevalence is rapidly increasing in children. We investigated in this study if the upper-normal TSH level may be associated with metabolic syndrome parameters, including obesity, high blood pressure, and dyslipidemia and changes in insulin sensitivity in overweight and obese children. We also investigated whether there is a relationship between BMI and these parameters. This prospective case-control study comprised 145 participants (74 females, 71 males) aged 5-18 years. Participants were divided into three groups according to their BMI z-score, as overweight, obese and control. The control group included 35 age and sex-matched healthy subjects. Thyroid stimulating hormone levels of control, overweight and obese groups were 2.14 ± 1.27, 2.97 ± 1.26 and 3.13 ± 1.11, respectively (p<0.05). There was a significant positive correlation between TSH and the BMI, BMI z-scores between overweight and obese groups (r=0.302, p=0.000), (r=0.121, p=0.004), respectively. The current study suggests that increased serum TSH levels, even within the normal range, in overweight and obese children is associated with the impairment of metabolic parameters, including dyslipidemia and insulin sensitivity. For that reason, TSH levels in the high-normal range should be considered as a risk factor for metabolic syndrome and its components.

Resumen La obesidad se considera un importante desafío de salud pública mundial y su prevalencia está aumentando rápidamente en los niños. En este estudio, se investigó si el nivel normal superior de TSH puede estar asociado con los parámetros del síndrome metabólico, incluida la obesidad, la presión arterial elevada, cambios en los lípidos y la sensibilidad a la insulina, en niños con sobrepeso y obesidad. También investigamos si existe una relación entre el IMC y estos parámetros. En este estudio prospectivo de casos y controles se incluyeron a 145 participantes (74 hembras, 71 varones) de entre 5 y 18 años. Los participantes se dividieron en 3 grupos según el puntaje z del IMC, como sobrepeso, obesidad y control. El grupo de control incluyó 35 sujetos sanos emparejados por edad y sexo. Los niveles de hormona estimulante de la tiroides de los grupos de control, con sobrepeso y obesos fueron 2,14 ± 1,27, 2,97 ± 1,26 y 3,13 ± 1,11, respectivamente (p <0,05). Hubo una correlación positiva significativa entre la TSH y el BMI, la puntuación z del IMC entre los grupos con sobrepeso y obesidad (r = 0,302, p = 0,000), (r = 0,121, p = 0,004), respectivamente. Por esa razón, el nivel de TSH en el rango normal alto debe considerarse como un factor de riesgo del síndrome metabólico y sus componentes.

Prognostic value of 18F-FDG PET/CT parameters and histopathologic variables in head and neck cancer / Valor prognóstico de parâmetros de PET/TC com 18F-FDG e variáveis histopatológicas em câncer de cabeça e pescoço

Abstract Introduction 18F-fluorodeoxyglucose positron emission tomography/computed tomography parameters such as; maximum standardized uptake values, standard metabolic tumor volume and otal lesion glycosis are important prognostic biomarkers in cancers. Objective To investigate the prognostic value of these parameters in patients with head and neck cancers. Methods We performed a retrospective study including 47 patients with head and neck cancer who underwent18F-fluorodeoxyglucose positron emission tomography/computed tomography prior to treatment. Standard metabolic tumor volume, otal lesion glycosis and standardized uptake were measured for each patient. The prognostic value of quantitative 18F-fluorodeoxyglucose positron emission tomography/computed tomography parameters and clinicopathologic variables on disease free survival and overall survival were analyzed. Results The median (range) standard metabolic tumor volume and otal lesion glycosis and standardized uptake were 7.63 cm3 (0.6-34.3), 68.9 g (2.58-524.5 g), 13.89 (4.89-33.03 g/mL), respectively. Lymph node metastases and tumour differentiation were significant variables for disease free survival and overall survival, however, all 18F-fluorodeoxyglucose positron emission tomography/computed tomography parameters were not associated with disease- free survival and overall survival. Conclusion Pretreatment quantities positron emission tomography parameters did not predict survival in head and neck cancer.

Resumo Introdução Os parâmetros da tomografia por emissão de pósitrons/tomografia computadorizada com 18F-fluordesoxiglicose, como os máximos valores de captação padronizados, o volume metabólico tumoral padrão e a glicólise total da lesão são importantes biomarcadores prognósticos de câncer. Objetivo Investigar o valor prognóstico desses parâmetros em pacientes com câncer de cabeça e pescoço. Método Fizemos um estudo retrospectivo que incluiu 47 pacientes com câncer de cabeça e pescoço e que foram submetidos à tomografia por emissão de pósitrons/tomografia computadorizada com 18F-fluordesoxiglicose antes do tratamento. Volume metabólico tumoral, glicólise total da lesão e valores de captação padronizados foram aferidos em cada paciente. O valor prognóstico de parâmetros quantitativos da tomografia por emissão de pósitrons/tomografia computadorizada com 18F-fluordesoxiglicose e das variáveis clínico-patológicas sobre a sobrevida livre de doença e a sobrevida geral foi analisado. Resultados A média (intervalo) de volume metabólico tumoral e glicólise total da lesão e valores de captação padronizados foram 7,63 cm3 (0,6-34,3), 68,9 g (2,58-524,5) e 13,89 g/mL (4,89-33,03), respectivamente. Metástase nos nódulos linfáticos e diferenciação tumoral foram variáveis significativas de sobrevida livre de doença e sobrevida geral; contudo, nenhum parâmetro da tomografia por emissão de pósitrons/tomografia computadorizada com 18F-fluordesoxiglicose estava associado a sobrevida livre de doença e sobrevida geral. Conclusão As quantidades dos parâmetros da tomografia por emissão de pósitrons pré-tratamento não previram a sobrevida em câncer de cabeça e pescoço.

Efeito da suplementação de colina protegida no perfil metabólico e intervalo entre parto e concepção de vacas leiteiras / Prepartum supplementation of protected choline on metabolic profile and interval between calving and conception of dairy cows

Durante o periparto, as vacas leiteiras são submetidas a uma grande demanda de energia, ao mesmo tempo em que reduzem sua ingestão de matéria seca. O balanço energético negativo, resultante dessa equação, acarreta severos transtornos metabólicos, à produção e, principalmente, à reprodução. O objetivo do presente estudo foi avaliar o efeito da colina protegida sobre os parâmetros metabólicos, o intervalo entre parto e concepção e a produção de leite em vacas no período de transição. Cinquenta e quatro vacas leiteiras foram divididas em três grupos: controle, suplementação com colina por 10 dias pré-parto (T10) e suplementação com colina por 20 dias pré-parto (T20). Após o parto, foram mensurados os teores de frutosamina, colesterol, ácidos graxos não esterificados (AGNE), beta-hidroxibutirato (BHB), aspartato aminotransferase (AST), gamaglutamiltransferase (GGT) e total de oxidantes (TOS), nos dias 10, 20 e 30. Ainda foram avaliadas produção de leite e intervalo entre parto e concepção. Não houve efeito da suplementação com colina sobre os parâmetros sanguíneos e a produção. O intervalo entre parto e concepção foi menor no grupo T20. A colina suplementada por 20 dias durante o pré-parto melhorou a performance reprodutiva de vacas leiteiras(AU)

During the periparturient dairy cows undergo a large energy demand, at the same time reducing their intake of dry matter. The negative energy balance resulting from this equation leads to severe metabolic disorders in production, and mainly in reproduction. The aim of this study was to evaluate the effect of protected choline on metabolic parameters, reproductive performance, and milk production in cows during the transition period. Fifty-four dairy cows were divided into three groups: control, supplementation with choline for 10 days prepartum (T10) and supplementation with choline for 20 days prepartum (T20). After delivery we measured fructosamine levels, cholesterol, non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), aspartate aminotransferase (AST), gamma glutamyltransferase (GGT), and total oxidant (TOS) on days 10, 20 and 30. We also evaluated milk production and interval between calving and conception. There was no effect of supplementation with choline on blood and production parameters. The interval between calving and conception was lower in the T20 group. Choline supplemented by 20 during the antepartum improved reproductive performance of dairy cows, although it did not change the metabolic profile.(AU)

Ketogenic diets in weight loss: a systematic review under physiological and biochemical aspects of nutrition / Dietas ketogénicas en la pérdida de peso: una revisión sistemática bajo aspectos fisiológicos y bioquímicos de la nutrición

Countless strategies have been proposed to change dietary patterns to promote weight loss. Many of these strategies are controversial, with questions of effectiveness and possible negative consequences to health, even if weight loss effects are achieved. Ketogenic diets, with or without calorie restrictions, are framed in this context. In the present systematic review, evidence on ketogenic diets for weight loss was investigated. Studies on ketogenic diet with or without calorie restriction related to weight loss published between 2012 and 2017 were selected from MEDLINE, Scielo and Web of Science databases. Results show there is a lack of knowledge on specific physiological mechanisms involved in the ketogenic diet. Much of the evidence published, despite showing specific effects on weight loss, BMI and fat percentage reduction, did not precisely assess its effects on specific physiological and biochemical parameters, mainly on the hepatic, cardiac and renal tissues. We conclude that strategies to control overweight and obesity do not necessarily need to impose restrictions on certain nutrients, especially carbohydrates, or increase the intake of food groups whose excessive consumption has been associated with different pathologies.

Innumerables estrategias se han propuesto para cambiar el patrón de la dieta y así promover la pérdida de peso. Muchas de estas estrategias aún son controversiales con respecto a la efectividad y las consecuencias negativas para la salud. Las dietas cetogénicas, con o sin restricciones calóricas, se enmarcan en este contexto. En la presente revisión sistemática, se investigaron las evidencias sobre las dietas cetogénicas para la pérdida de peso. Para esto, se seleccionaron los estudios de dieta cetogénica con o sin restricción calórica relacionada con la pérdida de peso publicados entre 2012 y 2017 a través de las bases de datos MEDLINE, Scielo y Web of Science. Los resultados muestran falta de conocimiento sobre mecanismos fisiológicos específicos implicados en la dieta cetogénica. Gran parte de la evidencia publicada, a pesar de mostrar efectos específicos sobre la pérdida de peso, IMC y reducción del porcentaje de grasa, no evaluó con precisión sus efectos sobre parámetros fisiológicos y bioquímicos, principalmente en los tejidos hepático, cardíaco y renal. Concluimos que las estrategias para controlar el sobrepeso y la obesidad no necesariamente tienen que imponer restricciones sobre nutrientes, especialmente los carbohidratos, o aumentar la ingesta de grupos de alimentos cuyo consumo excesivo se ha asociado con diferentes patologías.

Application of Metabolic Parameters Measured by ¹⁸F-FDG PET/CT in the Evaluation of the Prognosis of Non-small Cell Lung Cancer / 中国肺癌杂志

Tumor-node-metastasis (TNM) staging system is the most important basis for making therapeutic decisions and predicting prognosis of lung cancer patients. The metabolic parameters including standardized uptake value (SUV), metabolic tumor volume (MTV) and total lesion glycolysis (TLG) measured by ¹⁸F-fluorodeoxyglucose-positron emission tomography (¹⁸F-FDG PET/CT) associate with tumor aggressiveness and can provide additional prognostic information. A new staging methodology combines the conventional cTNM with the metabolic tumor burden quantified from the PET images is a better predictor of overall survival with superior stratifying power may help oncologists to make better treatment plans. ¹⁸F-FDG PET/CT image texture analysis, as an emerging research tool, is used to quantify the spatial heterogeneity of radioactive uptake in tumors, thereby to explore the biological characteristics of the tumor. This article reviews developments in evaluating the ¹⁸F-FDG PET/CT metabolic parameters and its role as a prognostic factor for non-small cell lung cancer.

Biochemical profile of Mangalarga Marchador mares during the last third of pregnancy, foaling and lactation / Perfil bioquímico de éguas da raça Mangalarga Marchador durante o terço final da gestação, parto e lactação

ABSTRACT: Adaptive changes in metabolism may occur under specific physiological conditions, being necessary the knowledge of the biochemical constituents that can undergo variations during the sixty days before foaling, until the first sixty days of lactation. The present study aimed to identify and evaluate the biochemical profile of Mangalarga Marchador mares during the last third of pregnancy, foaling and lactation. For this, 48 mares were used, which formed a maintenance group (MG), composed of non-pregnant mares and an experimental group, called the transition group (TG), formed by pregnant mares. Blood samples were collected at the following times: MG was evaluated in a single time (beginning of all collections); TG was evaluated in seven times [T-60, T-30, T-15 (days before foaling), T0 (first six hours after foaling), T15, T30, T60 (days after foaling)]. All animals were submitted to biochemical analysis, in which the concentrations of total calcium, chloride, phosphorus, magnesium, sodium, potassium, uric acid, creatinine, and urea were measured. The two groups differed significantly (P<0.05) in calcium, magnesium, sodium, potassium, creatinine, uric acid and urea concentration. Variation between times was also observed for these compounds. However, chloride and phosphorus did not differ between MG and TG. It was concluded that the last third of pregnancy, foaling and lactation exerts major influence on the biochemical constituents of blood through adjustments to maintain homeostasis in mares.

RESUMO: Mudanças adaptativas no metabolismo podem ocorrer em condições fisiológicas específicas, sendo necessário o conhecimento dos constituintes bioquímicos que possam sofrer variações durante os sessenta dias antes do parto, até os primeiros sessenta dias de lactação. O presente estudo teve como objetivo identificar e avaliar o perfil bioquímico de éguas Mangalarga Marchador no terço final da gestação, parto e lactação. Para isso, foram utilizadas 48 éguas, que formaram um grupo em manutenção (GM), composto por éguas não prenhes e um grupo experimental, chamado de grupo de transição (GT), formado por éguas gestantes. As coletas de sangue foram realizadas nos seguintes tempos: GM foi avaliada em um único tempo (início de todas as coletas); GT foi avaliado em sete tempos [T-60, T-30, T-15 (dias antes do parto), T0 (primeiras seis horas após o parto), T15, T30, T60 (dias após o parto)]. Todos animais foram submetidos as análises bioquímicas, em que foram mensuradas as concentrações de cálcio total, sódio, potássio, cloreto, fósforo, magnésio, ácido úrico, creatinina e ureia. Os dois grupos diferiram significativamente (P<0,05) nas concentrações de cálcio total, magnésio, sódio, potássio, creatinina, ácido úrico e ureia. Variações entre tempos também foram observadas nesses componentes. Entretanto, cloreto e fósforo não diferiram entre GM e GT. Conclui-se que o terço final da gestação, parto e lactação exerce forte influência sobre os constituintes bioquímicos do sangue por meio de ajustes para manter a homeostase nas éguas.

Evaluating the Predictive Ability of Initial Staging F-18 FDG PET/CT for the Prognosis of Non-HodgkinMalignant Lymphoma Patients Who Underwent Stem Cell Transplantation / 대한핵의학회잡지

OBJECTIVES: This study aimed to determine the value of clinical prognostic factors and semiquantitative metabolic parameters from initial staging fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) in non-Hodgkin lymphoma (NHL) patients treated with stem cell transplantation (SCT).METHODS: A total of 39 malignant lymphoma patients who underwent initial staging F-18 FDG PET/CT were enrolled in this study. SUVmax, MTV_wb, and TLG_wb were measured during the initial staging PET/CT. Receiver operating characteristic curve (ROC) analysis was adopted to dichotomize continuous variables. Log-rank test and Cox proportional hazard regression analysis were used to evaluate disease-free survival (DFS) rate.RESULTS: Among the 39 patients with malignant lymphoma, 17 (43.6%) had a relapse. For several clinical factors such as age, ECOG performance score, AMC/ALC score, stages, and revised International Prognostic Index score, differences between the two dichotomized groups were statistically insignificant. In univariate analysis, DFS estimates were 71.0 ± 7.8 months and 18.0 ± 5.9 months in high-SUVmax and low-SUVmax group, respectively (P < 0.01). For MTV_wb, DFS estimates were 46.6 ± 12.4 months and 69.1 ± 8.5 months in high-MTV_wb and low-MTV_wb group, respectively (P = 0.12). For TLG_wb, DFS estimates were 65.3 ± 7.5 months and 13.7 ± 8.6 months in high-TLG_wb and low-TLG_wb group, respectively (P = 0.02). In Cox proportional hazard regression analysis, only MTV_wb showed statistical significance (HR 3.01, 95% CI 1.04−8.74, P = 0.04).CONCLUSION: In NHL patients treated with SCT, the MTV_wb of initial staging F-18 FDG PET/CTwas an independent prognostic factor.

The Relationship of eNOS, p22 phox, CETP and ESR1 Gene Polymorphisms Related to Endocrine-Metabolic Parameters and Metabolic Syndrome in Postmenopausal Women - A Sample Population Based Study.

Aims: To investigate the endocrine-metabolic changes in postmenopausal women with MetS and examine relationship with the polymorphisms of eNOS-G894T, p22(phox)-930 A/G, CETP TaqIB, ESR1 (PvuII and XbaI) genes. Methods: 280 postmenopausal apparently healthy women aged between 60 and 80 years were classified into non-MetS (212) and MetS (68). Clinical, anthropometric and endocrine-metabolic parameters were measured. The single nucleotide polymorphisms were determined and tested for interacting with these parameters. Results: The weight, waist circumference, blood pressure, WBC, triglycerides, LDL-C, TG/HDL-C ratio, apolipoprotein (apo)B, apoB/apoA-I ratio, fasting glucose, insulin, HOMA, uric acid, were higher and HDL-C was lower in MetS group thus fulfilled the criteria for the MetS. The significant higher levels of E2, T3, GHBP, PTH and lower levels of cortisol, SHBG, FSH, LH, IGFBP1, cortisol/DHEA ratio were also detected. Genetic association studies showed that presence of A allele p22phoxA/G (OR=1.62; CI=1.08-2.42) and heterozygote AG-XbaI(ESR1) (OR=2.29; CI= 1.19-4.37) indicated a significant risk for MetS. The binary logistic regression (MetS vs Controls) showed an interaction of G894TeNOS polymorphism with MetS (OR>2.5; 95% CI =1.47-4.90) that associated with SBP, TG, apoB, uric acid, ASTGOT (OR>1) and HDL-C (OR<1). CETP TaqIB polymorphism associated with MetS (OR<1) in presence of SBP, GLU, TG with OR>1. ESR1 PvuII (T/C) associated with MetS (OR between 1.59-8.60) in presence of LDL-C, TG/HDL-C ratio, P with OD>1 and HDL-C, androstenedione, SHBG, FAI with OR<1. In MetS group the carriers of -TT (eNOS-G894T) genotype had higher levels of blood pressure, glucose; -GG (p22phox A/G) had higher levels of BMI, apoB/apoA ratio; -B1B2 (CETP B1/B2) had higher levels of SBP, glucose, cholesterol, HDL-C, CRP, GHBP and lower levels of TSH; -CC (PvuII) and GG (XbaI) ESR1 genotypes showed higher levels of glucose. Conclusions: These results sustain an interaction between the studied polymorphisms and the endocrine-metabolic changes in MetS pathogenesis.

Association between Circulating Betatrophin Levels and Metabolic Parameters in Non-alcoholic Fatty Liver Disease Patients / 实用医学杂志

Objective To investigate circulating betatrophin levels in non-alcoholic fatty liver disease patients (NAFLD). To explore its association with various metabolic parameters in Chinese subjects. Methods From August 2014 to April 2015 , 58 patients with NAFLD and 41 non-NAFLD control subjects with age and sex matched were enrolled in the Department of Endocrinology of Zhujiang Hospital. Results In NAFLD group, serum betatrophin concentrations significantly increased (781.96 vs. 431.89 pg/mL, P < 0.05) and associated only with HDL-cholesterol level. In normal group, betetrophin levels are associated with multiple metabolic parameters, such as fasting glucose, insulin, C peptide, HOMA-IR, QUICK index and HDL-C levels. Conclusions Serum betatrophin concentration significantly elevated in non-alcoholic fatty liver disease patients and was negatively correlated with HDL-C level (r = -0.479, P < 0.001).

Efectos del consumo elevado de fructosa y sacarosa sobre parámetros metabólicos en ratas obesas y diabéticas / Effects of a high fructose and sucrose intake on metabolic parameters in obese diabetic rats

The relationship between a high consumption of fructose-sweetened foods and obesity and its co-morbidities remains controversial. In this study the effects of three isocaloric and isolipidic diets containing different carbohydrates - fructose, sucrose and starch (AIN 93) - on biomass, abdominal fat depots, blood and liver lipid profile and hepatic histopathology in adult male IIMb/obese and diabetic rats were evaluated. Plasma cholesterol and triacylglycerol were significantly higher in fructose and sucrose groups, while liver lipids showed higher levels in the starch-fed group. There were no differences in hepatic histology in the three groups. The findings of this study support the hypothesis that sugar-rich diets -with fructose or sucrose - replacing starch in equivalent amounts produce similar effects in plasma glucose-lipid profile.

La controversia acerca de si el alto consumo de fructosa ha sido determinante en la prevalencia actual de la obesidad y sus comorbilidades, o si sus efectos son semejantes a los de un consumo equivalente de otros azúcares continúa vigente. En este trabajo se evaluaron los efectos de tres dietas isocalóricas e isolipídicas con fructosa, sacarosa o almidón -como control-, sobre la biomasa, el depósito adiposo abdominal, el perfil glucolipídico sanguíneo y los lípidos y la histología hepáticos en ratas adultas IIMb/β, obesas y diabéticas. Los valores de colesterol y triacilgliceroles plasmáticos fueron mayores en los grupos alimentados con fructosa y sacarosa, mientras que los lípidos hepáticos resultaron mayores en el grupo que consumió almidón. La histología hepática mostró leve esteatosis micro-macro vacuolar en los tres grupos. Los efectos de fructosa y sacarosa sobre las variables evaluadas no fueron diferentes.

Lipocalin-2 is an inflammatory biomarker associated with metabolic abnormalities in Egyptian obese children.

Background: The aim of the study was to explore the relationships of lipocalin-2 with metabolic risk factors in obese prepubertal children. Methods: The aim of the study is to examine relationship between serum lipocalin-2 concentrations and metabolic risk factors in 80 obese children and compared with 80 age and sex matched non-obese children controls. Anthropometric and biochemical parameters were measured by standard procedures. Insulin resistance was determined by Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). Results: In the present cross –section study serum lipocalin-2, leptin, insulin, HOMA-IR blood pressure, triglycerides and low-density lipoprotein (LDL-c) and cholesterol were significantly higher in obese children than non-obese, whereas high-density lipoprotein cholesterol (HDL-c) was significantly lower. After adjustment of lipocalin-2 levels for BMI, age and gender, the correlation between serum lipocalin-2 with weight, waist circumference, body fat % and metabolic variables such as fasting insulin; glucose and HOMA-IR triglycerides, cholesterol, LDL-C and HDL-C remained significant. The stepwise multiple regression analysis showed that lipocalin-2 levels were independently associated with LDL-c, total cholesterol, triglycerides and HOMA-IR. Conclusions: lipocalin-2 was significantly elevated in prepubertal obese children and was independently associated with adiposity parameters and its related metabolic complications. The present findings suggest that the measurement of this biomarker may be useful for evaluating metabolic syndrome in Egyptian obese children.

A Study on Changes of Metabolic Parameters with Antipsychotic Treatment in Schizophrenic Patients : 1 Year Prospective Natualistic Study / 대한정신분열병학회지

OBJECTIVES: Schizophrenia patients are known to be more prone to metabolic disease than normal people. This study aimed to identify the changes in metabolic parameters of schizophrenia patients using atypical antipsychotic drugs for 1 year. METHODS: A total of 200 schizophrenia patients were recruited and categorized into the aripiprazole-treatment group and control group taking 5 atypical antipsychotic drugs. Comparative analysis were between groups. The prescriptions of psychotropic drugs were collected by a review of medical records. Blood was collected after fasting for 12 hours at the starting point of treatment and the 12th month, and patient medical records were evaluated for basici nformation and treatment history. Physical measurement, the prevalence of metabolic syndrome and metabolic parameters were studied using ATP-III diagnostic criteria. RESULTS: From the study, the aripiprazole-treatment group had a mean weight increase of 0.6 kg and the control group had a mean weight increase of 6.5 kg at the 1 year follow-up, showing a significant difference between the two groups. There were also significant differences between the two groups in waist size, systolic and diastolic blood pressure, fasting blood sugar, total cholesterol, triglyceride, HDL-choleseterol and prolactin level. Along with meaningful improvement of the symptoms, aripiprazole-treatment group showed less effect on in abdominal obesity, diabetes, blood pressure, cholesterol and prolactin than other atypical antipsychotic drugs. CONCLUSION: Therapeutic intervention such as diagnosis, treatment, weight management and diet improvement is necessary for schizophrenia patients. Psychiatric symptoms as well as internal meicine-related problems such as metabolic disease need to be addressed in case management.

Prevalence of Metabolic Syndrome in Patients with Essential Hypertension.

The objective of this study was to study the prevalence of metabolic syndrome among patients with essential hypertension and to correlate metabolic parameters. It was a noninterventional, observational study in which 172 patients having essential hypertension who fulfilled the inclusion criteria were included and all were subjected to a uniform questionnaire, medical examination and investigations. Prevalence of metabolic syndrome was 55.23% in patients with essential hypertension in this study, more common in females and most common in age group between 40 and 50 years (39.60%). Low high-density lipoprotein cholesterol (HDL-C) level was the most common metabolic abnormality detected in patients with metabolic syndrome followed by an abnormal fasting blood sugar (FBS), abnormal waist circumference and abnormal triglyceride (TG) level. The females had an abnormal HDL-C levels in 92.06% (z = 16.19, p < 0.05) followed by an abnormal waist circumference in 61.90% (z = 6.85, p < 0.05). The FBS and TG were abnormal in 60.3% (z = 3.34, p < 0.05) and 50.7% (z = 2.57, p < 0.05), of female patients, respectively, while in males, the most common abnormality was low HDL-C in 87.5% (z = 12.54, p < 0.05) followed by abnormal TG levels in 65.62% (z = 3.71, p < 0.05), abnormal FBS 62.5%, (z = 2.92, p < 0.05) and abnormal waist circumference 40.62% (z = 2.14, p < 0.05). TG/HDL-C ratio of ≥3 was the variable that had the best correlation (p = 0.534) with the presence of metabolic syndrome.

Retrospective surveillance of metabolic parameters affecting reproductive performance of Japanese Black breeding cows

This retrospective study was conducted to confirm the relationship between pre- and postpartum metabolic parameters and postpartum reproductive performance and to clarify seasonal characteristics of the metabolic parameters by using our metabolic profile test (MPT) database of Japanese Black breeding herds. In evaluation 1, MPT databases of blood samples from multiparous cows collected prepartum and postpartum were divided into two groups according to calving interval, and each MPT parameter was compared. In evaluation 2, the same MPT databases used in evaluation 1 were divided into two groups according to the sampling period. Significant differences were found in the prepartal total protein and postpartal gamma-glutamyltransferase in evaluation 1. In evaluation 2, significant differences were found in the prepartal and postpartal total protein, albumin/globulin ratio, and glucose. Clear seasonal differences in MPT results emphasized the usefulness of the MPT in breeding cattle herds fed home-pasture roughage and suggest that unsatisfactory reproductive performance during hot periods reflects inadequate nutritional content of the diet and possible reduced feed intake due to heat stress.

There was no significant difference in HbA1c control and prevalence of dyslipidemia and hyperuricemia between two groups. Conclusion SCH may have some adverse effects on blood pressure and BMI in T2DM.

Aged garlic extract enhances exercise-mediated improvement of metabolic parameters in high fat diet-induced obese rats

Aged garlic extract (AGE) is known to have a protective effect against immune system, endothelial function, oxidative stress and inflammation. We examined the effects of exercise with and without aged garlic extract administration on body weight, lipid profiles, inflammatory cytokines, and oxidative stress marker in high-fat diet (HFD)-induced obese rats. Forty-five Sprague-Dawley rats were fed either a HFD (HFD, n = 40) or a normal diet (ND, n = 5) for 6 weeks and thereafter randomized into ND (n = 5), HFD (n = 10), HFD with AGE (n = 10), HFD with Exercise (n = 10), or HFD with Exercise+AGE (n = 10) for 4 weeks. AGE groups were administered at a dose of 2.86 g/kg.body weight, orally. Exercise consisted of running 15-60 min 5 days/week with gradually increasing intensity. AGE (P < 0.01), Exercise, and Exercise+AGE (P < 0.001) attenuated body weight gain and food efficiency ratio compared to HFD. Visceral fat and liver weight gain were attenuated (P < 0.05) with all three interventions with a greater effect on visceral fat in the Exercise+AGE than AGE (P < 0.001). In reducing visceral fat (P < 0.001), epididymal fat (P < 0.01) and liver weight (P < 0.001), Exercise+AGE was effective, but exercise showed a stronger suppressive effect than AGE. Exercise+AGE showed further additive effects on reducing visceral fat and liver weight (P < 0.001). AGE significantly attenuated the increase in total cholesterol and low-density lipoprotein-cholesterol compared with HFD (P < 0.05). Exercise+AGE attenuated the increase in triglycerides compared with HFD (P < 0.05). Exercise group significantly decrease in C-reactive protein (P < 0.001). These results suggest that AGE supplementation and exercise alone have anti-obesity, cholesterol lowering, and anti-inflammatory effects, but the combined intervention is more effective in reducing weight gain and triglycerides levels than either intervention alone.

A influência de 16 semanas de exercícios físicos combinados sobre o perfil metabólico em idosas / The effect of 16 weeks exercise combined on the metabolic parameters in elderlies

O envelhecimento é um processo multifatorial influenciado por aspectos psicológicos, sociais, biológicos e funcionais. O objetivo do presente estudo foi verificar os benefícios de exercícios físicos combinados que contemplou a prática de jogos lúdicos, exercícios de flexibilidade, localizados, equilíbrio e caminhada com intensidade moderada, sobre o perfil metabólico de idosas. 54 idosas foram divididas em dois grupos. O grupo experimental (GE) foi composto por 33 sujeitos onde as idades variaram entre 60 a 87 anos (68,9 ± 6,8 anos), enquanto o grupo controle (GC) foi composto por 21 sujeitos com a faixa etária variando entre 61 a 81 anos (66,5 ± 6,0 anos). Para coleta de dados dos parâmetros metabólicos, foram realizados exames sanguíneos dos indicadores colesterol total (CT), HDL colesterol, LDL colesterol, VLDL colesterol, triglicerídeos e glicose. O GE obteve melhoras significativas nos parâmetros metabólicos após todos seus indicadores sanguíneos avaliados. O CT teve uma queda de 228,0 para 190,5. O LDL passou de 162,4 para 115,2. O VLDL passou de 31,5 para 29,7. O TRI passou de 127,5 para 105,1. A GLI passou de 94,8 para 85,9. O HDL teve um aumento em seu valor passando de 48,4 para 53,4. Para o GC esta melhora não foi encontrada, exceto para o Colesterol Total que teve seus valores alterados de 220,0 para 198,3. Assim, os exercícios físicos combinados exerceram importante papel na melhoria geral de saúde da população estudada em todos os parâmetros avaliados.

Aging is a multifactor process influenced by chronological time, by psychological aspects, social, biological and functional. The objective of this study was to assess the benefits of exercise combined, with moderate intensity, on the metabolic parameters in elderly. 54 elderly women were divided into two groups. The experimental group (GE) consisted of 33 subjects where the ages ranged from 60-87 years with mean (68.93 ± 6.83), while the control group (GC) consisted of 21 subjects with age ranging from 61-81 years, mean (6.00 ± 66.55). To collect data, metabolic parameters, blood tests were performed for total cholesterol, HDL cholesterol, LDL cholesterol, VLDL Cholesterol, Triglycerides and Glucose. The results of GE in relation to metabolic parameters analyzed were significant improvements after practice activities in all their indicators assessed blood. For the GC the same improvement was not found, only the total cholesterol showed significant improvement. It is concluded that physical activity combined exerted important role in improving general health of population in all parameters tested in GE which likely will entail a greater longevity of the population with good quality.

Metabolic profile and cardiovascular risk factors among Latin American HIV-infected patients receiving HAART

OBJECTIVE: Determine the prevalence of metabolic abnormalities (MA) and estimate the 10-year risk for cardiovascular disease (CVD) among Latin American HIV-infected patients receiving highly active anti-retroviral therapy (HAART). METHODS: A cohort study to evaluate MA and treatment practices to reduce CVD has been conducted in seven Latin American countries. Adult HIV-infected patients with at least one month of HAART were enrolled. Baseline data are presented in this analysis. RESULTS: A total of 4,010 patients were enrolled. Mean age (SD) was 41.9 (10) years; median duration of HAART was 35 (IQR: 10-51) months, 44 percent received protease inhibitors. The prevalence of dyslipidemia and metabolic syndrome was 80.2 percent and 20.2 percent, respectively. The overall 10-year risk of CVD, as measured by the Framingham risk score (FRF), was 10.4 (24.7). Longer exposure to HAART was documented in patients with dyslipidemia, metabolic syndrome and type 2 diabetes mellitus. The FRF score increased with duration of HAART. Male patients had more dyslipidemia, high blood pressure, smoking habit and higher 10-year CVD than females. CONCLUSIONS: Traditional risk factors for CVD are prevalent in this setting leading to intermediate 10-year risk of CVD. Modification of these risk factors through education and intervention programs are needed to reduce CVD.
