ABSTRACT

A síndrome dos ovários policísticos (SOP) é frequentemente acompanhada de distúrbio metabólico, principalmente dos carboidratos e dos lipídeos, aumentando o risco de síndrome metabólica. Por essa razão, alguns investigadores ainda denominam a SOP de síndrome metabólica-reprodutiva. O objetivo deste capítulo é descrever as principais repercussões metabólicas, bem como como investigá-las e saber como suas consequências podem ser deletérias para a saúde da mulher. Esta é uma revisão narrativa mostrando a implicação do metabolismo dos carboidratos e dos lipídeos nas dislipidemias, bem como da síndrome metabólica sobre o sistema reprodutor, e o risco cardiovascular da mulher com SOP. Conclui-se que o manejo adequado dos distúrbios metabólicos na SOP é benéfico a curto e a longo prazo tanto para o sistema reprodutor quanto para o cardiovascular.(AU)

ABSTRACT

INTRODUCCIÓN: El riesgo cardiovascular (RCV) se define como la posibilidad que tiene un sujeto de sufrir una enfermedad cardiovascular dentro de un determinado plazo de tiempo. Si bien la patología se hace sintomatica en etapa adulta, los cambios fisiopatológicos comienzan a desarrollarse en edades tempranas. OBJETIVO: Establecer la relación entre capacidad cardiorrespiratoria, estimada a través de la prueba de caminata de seis minutos (PC6M), y el RCV en niños con síndrome metabólico. PACIENTES Y MÉTODO: Se analizaron 42 niños, edad 5 a 15 años, que asistieron a la Unidad de Cardiología Infantil del Hospital Carlos Van Buren entre los años 2015 y 2017. Cada participante se categorizó de acuerdo al puntaje de RCV de Alustiza, que define 3 niveles de riesgo: bajo (0 a 6 puntos), medio (7 a 8 puntos) y alto (9 o más puntos), lo que se traduciría en una mayor probabilidad de desarrollar una enfermedad cardiovascular, y realizó concomitantemente la PC6M. RESULTADOS: La edad media del grupo de ni ños fue de 10,9 ± 2,7 años, con un Índice de Masa Corporal (IMC) = 31,0 ± 4,6 kg/m2 (z-score 3,2 ± 0,7). Los niños recorren 75,2 ± 8,9 por ciento de la distancia teórica, con un porcentaje de frecuencia cardíaca de reserva (FCR) = 31,0 ± 9,4. No se observaron relaciones estadísticamente significativas entre RCV y PC6M. CONCLUSIONES: No se encuentra relación entre la capacidad cardiorrespiratoria y RCV. Se cuestiona la utilidad de la PC6M para valorar el RCV en la población de estudio.


INTRODUCTION: Cardiovascular risk (CVR) is defined as the possibility of a subject suffering from car diovascular disease within a certain period. Although the pathology appears in adult life, the physiopathological changes start to develop at an early age. OBJECTIVE: To establish the relationship bet ween cardiorespiratory capacity (CRC)and CVR in children with metabolic syndrome. PATIENTS AND METHODS: We analyzed data corresponding to 42 children aged from 5 to 15 years who were seen at the Children's Cardiology Unit of the Carlos Van Buren Hospital between 2015 and 2017. Each parti cipant was categorized according to the Alustiza's CVR score, which defines 3 levels of risk: low (0 to 6 points), medium (7 to 8 points) and high (9 or more points), which representing a greater probability of developing cardiovascular disease, and performed 6MWT. RESULTS: The mean age of the children was 10.9 ± 2.7 years, body mass index (BMI) = 31.0 ± 4.6 kg/m2 (z-score 3.2 ± 0.7), percentage of theoretical distance walked = 75.2 ± 8.9, and percentage of heart rate reserve (HRR) = 31.0 ± 9.4. There was no statistical association between 6MWT and CVR. CONCLUSIONS: There is no relationship between the cardiorespiratory capacity and the CVR. The use of the 6MWT is questioned as an ins trument to assess CVR in the population under study.

ABSTRACT

Evaluar los efectos de la terapia hormonal (TH) con Drospírenona (DRSP)/17 ß -estradiol (E2), sobre los parámetros del Síndrome Metabólico (SM) en pacientes postmenopáusicas. Métodos: Investigación comparativa y aplicada, con diseño cuasi experimental, de casos y controles a simple ciego, prospectivo y de campo; realizada en la Consulta de Ginecología. Hospital "Dr. Manuel Noriega Trigo". San Francisco, Estado Zulia. Venezuela. Participaron 120 mujeres separadas al azar para recibir la combinación DRSP/E2 (Grupo A) o un placebo (Grupo B). Se evaluaron los componentes del SM antes y posterior a 6 meses de haber recibido la TH. Resultados: Se encontró una alta prevalencia de SM en ambos grupos antes de recibir el tratamiento (53,3% y 48%; grupo A y B respectivamente). Posterior al tratamiento, DRSP/E2 al compararse con un placebo, redujo significativamente tanto la prevalencia del SM como el riesgo de padecerlo (21,7% versus 48,3%, OR [IC95%]= 0,29 [0,13-0,65]; p < 0.001), con reducción significativa (p< 0.001) de la hipertensión arterial, glicemia basal alterada, hipertrigliceridemia y obesidad central; además de una reducción significativa de los síntomas vasomotores, síntomas psicológicos e incontinencia urinaria (p< 0.001). En el grupo B la prevalencia del SM se mantuvo sin cambios, salvo para la glicemia basal alterada y los síntomas vasomotores y psicológicos que mostraron una reducción significativa (p< 0.001). Conclusión: DRSP/E2 (2mg/1 mg) demostró ser eficaz luego de 6 meses de tratamiento tanto para el control de los parámetros que definen al SM; con pocos y leves efectos indeseados(AU)

ABSTRACT

Metabolic syndrome is a multifaceted condition associated with a greater risk of various disorders (e.g., diabetes and heart disease). In a rat model of metabolic syndrome, an acute in vitro application of rosuvastatin causes relaxation of aortic rings. Since the outcome of a subchronic rosuvastatin treatment is unknown, the present study explored its effect on acetylcholine-induced vasorelaxation of aortic rings from rats with metabolic syndrome. Animals were submitted to a 16-week treatment, including a standard diet, a cafeteria-style diet (CAF-diet), or a CAF-diet with daily rosuvastatin treatment (10 mg/kg). After confirming the development of metabolic syndrome in rats, aortic segments were extracted from these animals (those treated with rosuvastatin and untreated) and the acetylcholine-induced relaxant effect on the corresponding rings was evaluated. Concentration-response curves were constructed for this effect in the presence/absence of L-NAME, ODQ, KT 5823, 4-aminopyridine (4-AP), tetraethylammonium (TEA), apamin plus charybdotoxin, glibenclamide, indomethacin, clotrimazole, and cycloheximide pretreatment. Compared to rings from control rats, acetylcholine-induced vasorelaxation decreased in rings from animals with metabolic syndrome, and was maintained at a normal level in animals with metabolic syndrome plus rosuvastatin treatment. The effect of rosuvastatin was inhibited by L-NAME, ODQ, KT 5823, TEA, apamin plus charybdotoxin, but unaffected by 4-AP, glibenclamide, indomethacin, clotrimazole, or cycloheximide. In conclusion, the subchronic administration of rosuvastatin to rats with metabolic syndrome improved the acetylcholine-induced relaxant response, involving stimulation of the NO/cGMP/PKG/Ca2+-activated K+ channel pathway.

ABSTRACT

Abstract Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF. However, the association among MAC, MetS and thromboembolic risk is unknown and was evaluated in the current study. Methods: The study group consisted of 94 patients with MAC and 86 patients with MetS. Patients were divided into two groups: those with and those without MAC. Results: Patients with MAC had a higher MetS rate (P<0.001). In patients with MAC, the CHA2DS2-VASc scores and the rate of cerebrovascular accident and AF were significantly higher compared to those without MAC (P<0.001, for both parameters). The results of the multivariate regression analysis showed that history of smoking, presence of MetS and high CHA2DS2-VASc scores were associated with the development of MAC. ROC curve analyses showed that CHA2DS2-VASc scores were significant predictors for MAC (C-statistic: 0.78; 95% CI: 0.706-0.855, P<0.001). Correlation analysis indicated that MAC was positively correlated with the presence of MetS and CHA2DS2-VASc score (P=0.001, r=0.264; P<0.001, r=0.490). Conclusion: We have shown that CHA2DS2-VASc score and presence of MetS rates were significantly higher in patients with MAC compared without MAC. Presence of MAC was correlated with CHA2DS2-VASc score, presence of MetS, AF and left atrial diameter and negatively correlated with left ventricular ejection fraction.

ABSTRACT

Abstract Objective: Given the importance of incorporating simple and low-cost tools into the pediatric clinical setting to provide screening for insulin resistance, the present study sought to investigate whether waist-to-height ratio is comparable to biochemical markers for the discrimination of insulin resistance in children and adolescents. Methods: This cross-sectional study involved students from nine public schools. In total, 296 children and adolescents of both sexes, aged 8 -14 years, composed the sample. Waist-to-height ratio, triglycerides/glucose index, and triglycerides-to-HDL-C ratio were determined according to standard protocols. Insulin resistance was defined as homeostatic model assessment for insulin resistance with cut-off point ≥ 3.16. Results: Age, body mass index, frequency of overweight, waist circumference, waist-to-height ratio, insulin, glucose, homeostatic model assessment for insulin resistance, triglycerides, triglycerides/glucose index, and triglycerides-to-HDL-C were higher among insulin resistant boys and girls. Moderate correlation of all indicators (waist-to-height ratio, triglycerides/glucose index, and triglycerides-to-HDL-C ratio) with homeostatic model assessment for insulin resistance was observed for both sexes. The areas under the receiver operational characteristic curves ware similar between waist-to-height ratio and biochemical markers. Conclusion: The indicators provided similar discriminatory power for insulin resistance. However, taking into account the cost-benefit ratio, we suggest that waist-to-height ratio may be a useful tool to provide screening for insulin resistance in pediatric populations.


Resumo Objetivo: Considerando a importância de incorporar ferramentas simples e de baixo custo no cenário clínico-pediátrico para a triagem de resistência à insulina, o presente estudo buscou investigar se a razão cintura/estatura é comparável a marcadores bioquímicos na discriminação de resistência à insulina em crianças e adolescentes. Métodos: Este estudo transversal envolveu estudantes de nove escolas públicas. No total, 296 crianças e adolescentes, de ambos os sexos, com idades entre 8 e 14 anos, compuseram a amostra. A razão cintura/estatura, o índice triglicerídeos/glicose e a razão triglicerídeos/HDL-C foram determinados de acordo com protocolos padrão. A resistência à insulina foi definida por meio do modelo de avaliação homeostática para resistência insulínica, com ponto de corte ≥ 3.16. Resultados: Idade, índice de massa corporal, frequência de excesso de peso, circunferência da cintura, razão cintura/estatura, insulina, glicemia, modelo de avaliação homeostática para resistência insulínica, triglicerídeos, índice triglicerídeos/glicose e razão triglicerídeos/HDL-C foram maiores entre meninos e meninas com resistência à insulina. Também foram observadas, em ambos os sexos, correlações moderadas de todos os indicadores (razão cintura/estatura, índice triglicerídeos/glicose e razão triglicerídeos/HDL-C) com o modelo de avaliação homeostática para resistência à insulina. As áreas sob as curvas ROC foram semelhantes entre a razão cintura/estatura e os marcadores bioquímicos. Conclusão: Os indicadores forneceram poder discriminatório similar para a resistência à insulina. No entanto, levando em conta o custo-benefício, sugerimos que a razão cintura/estatura pode ser uma ferramenta útil para a triagem de resistência à insulina em populações pediátricas.

ABSTRACT

La obesidad infantil representa un factor importante en el desarrollo del síndrome metabólico (SM). En este sentido el factor neurotrófico derivado del cerebro (BDNF: Brain Derived Neurotrophic Factor) interviene en el metabolismo energético así como en vías que controlan el peso corporal y desórdenes metabólicos. El objetivo de este estudio fue determinar si hay una correlación entre el BDNF con los marcadores que definen al síndrome metabólico en una población infantil de México. Se integraron al estudio 100 niños con un rango de edad de 5-13 años, se estratificaron en tres grupos, normo peso, sobrepeso y obesidad, a los cuales se les determinaron las variables antropométricas, percentil de la tensión arterial sistólica y diastólica, concentraciones séricas de glucosa, triglicéridos, colesterol de alta densidad (HDL) y BDNF. Se aplicó ANOVA y una correlación de Pearson. Los resultados muestran que la prevalencia de SM utilizando los criterios de Cook y Weiss fue del 14%, mientras que por la Federación Internacional de Diabetes (IDF) es del 11%. La circunferencia de cintura, triglicéridos, colesterol HDL, presión arterial sistólica/diastólica y glucosa, mostraron diferencias significativas entre los grupos estudiados (*p<0,001). El BDNF se correlacionó positivamente con la desviación estándar del índice de masa corporal de acuerdo con la edad (DE-IMCE) (p=0,01), el percentil del perímetro de la cintura (p=0,00), la presión arterial sistólica (p=0,01) y las concentraciones plasmáticas de glucosa (p=0,02). Estos datos muestran que existe una correlación entre el BDNF con la DE-IMCE, la circunferencia de la cintura, la presión arterial sistólica y glucosa(AU)


Childhood obesity represents an important factor in the development of metabolic syndrome (MS). In this sense, the brain derived neurotrophic factor (BDNF) is involved in energy metabolism as well as in pathways that control body weight and metabolic disorders. The objective of this study was to determine if there is a correlation between BDNF with the markers that define the metabolic syndrome in a child population in Mexico. The study included 100 children with an age range of 5-13 years, stratified into three groups, normal weight, overweight and obesity, which were determined anthropometric variables, percentile of systolic and diastolic blood pressure, concentrations serum glucose, triglycerides, high density cholesterol (HDL) and BDNF. ANOVA and Pearson correlation were applied. The results show that the prevalence of MS using the Cook and Weiss criteria was 14%, while for the International Diabetes Federation (IDF) it is 11%. Waist circumference, triglycerides, HDL cholesterol, systolic/diastolic blood pressure and glucose showed significant differences between the groups studied (*p<0.001). The BDNF was positively correlated with the standard deviation of the body mass index according to age (DE-IMCE) (p=0.01), the percentile of the waist circumference (p=0.00), systolic blood pressure (p=0.01) and plasma glucose concentrations (p=0.02). These data show that there is a correlation between BDNF with DE-IMCE, waist circumference, systolic blood pressure and glucose(AU)

ABSTRACT

ABSTRACT Objective: To evaluate the effects of 16 weeks of periodized aerobic interval training (AIT) on cardiac autonomic modulation and cardiovascular parameters of metabolic syndrome (Mets) individuals. Subjects and methods: The sample was composed of 52 subjects with a diagnosis of Mets, allocated into two groups: AIT (AITG; n = 26) and control (CG; n = 26). The AITG was submitted to a periodized AIT program, over 16 weeks, while CG was not submitted to any training program. To evaluate the autonomic modulation and cardiovascular parameters in both groups, heart rate variability (HRV) indices, blood pressure (BP), and heart rate (HR) were measured at the beginning and end of the training. Results: Statistically significant differences were not observed in HFms2 (high frequency in milisseconds), LFnu (low frequency in normality unit), HFnu (high frequency in normality unit), and LF/HF ratio indices, or in the cardiovascular parameters BP and HR when comparing the AITG with the CG. However, significant increases in rMSSD (root-means square differences of successive R-R intervals), LFms2 (low frequency in milliseconds), and SDNN (standard deviation of normal to normal intervals) were observed in the AITG. Conclusion: Periodized AIT promoted positive effects on autonomic modulation of Mets subjects, characterized by an increase in the parasympathetic, sympathetic, and global modulation of this population. Additionally, cardiovascular parameter alterations were not observed in Mets subjects submitted to periodized AIT.

ABSTRACT

ABSTRACT Objective: To identify which anthropometric measurement would be the best predictor of metabolic syndrome (MetS) in Brazilian adolescents. Subjects and methods: Cross-sectional study conducted on 222 adolescents (15-17 years) from a city in southern Brazil. Anthropometric, physical activity, blood pressure and biochemical parameters were investigated. MetS criteria were transformed into a continuous variable (MetS score). Linear regression analyses were performed to assess the associations of BMI, hip circumference, neck circumference (NC), triceps skinfold, subscapular skinfold and body fat percentage with MetS score. ROC curves were constructed to determine the cutoff for each anthropometric measurement. Results: The prevalence of MetS was 7.2%. Each anthropometric measurement was significantly (p < 0.001) associated with MetS score. After adjusting for potential confounding variables (age, sex, physical activity, and maternal education), the standardized coefficients of NC and body fat percentage appeared to have the strongest association (beta = 0.69 standard deviation) with MetS score. The regression of BMI provided the best model fit (adjusted R2 = 0.31). BMI predicted MetS with high sensitivity (100.0%) and specificity (86.4%). Conclusions: Our results suggest that BMI and NC are effective screening tools for MetS in adolescents. The early diagnosis of MetS combined with targeted lifestyle interventions in adolescence may help reduce the burden of cardiovascular diseases and diabetes in adulthood.

ABSTRACT

Background: Metabolic syndrome (MS) predisposes to left ventricular dysfunction and heart failure, however, alterations in left atrial (LA) function in MS are unknown. Objectives: We aimed to use strain/strain rate (SR) imaging to investigate the effect of MS on LA function. Subjects and Methods: This prospective case control study included a total of 100 subjects divided in to 75 metabolic syndrome (MS) patients referred to Al-Azhar university hospital outpatient clinic for evaluation and treatment of hypertension and/or diabetes mellitus and 25 age and sex matched apparently healthy volunteers as a control group. All subjects underwent conventional echocardiographic examination and assessment of LA function by speckle tracking. Partial correlation and multiple stepwise regression analyses were used to determine the risk factors for impaired LA function. Results: Compared with the controls, the MS patients showed significantly lower levels of mean strain, mean peak systolic SR and mean peak early diastolic SR (P<0.05 for all), with no difference in the mean peak late diastolic SR. Central obesity, hypertension, dyslipidemia and uncontrolled diabetes were independent risk factors for impaired LA function. Conclusion: SR imaging is reliable in assessing LA function in MS patients

ABSTRACT

ABSTRACT Objective: To estimate the prevalence of the metabolic syndrome and clusters of its components and to identify possible associated factors in older adults. Method: Cross-sectional and population-based study, involving 271 older people. We collected sociodemographic, behavioral, clinical, biochemical, and anthropometric data. Data were analyzed by descriptive and logistic regression techniques. Results: The prevalence of metabolic syndrome was 59% and was associated with women, overweight/obesity, and the C-reactive protein. Concerning the clusters, 11.4% of the sample had all the components of the metabolic syndrome, and only 5.2% of individuals did not have any of its components. Conclusion: We found there is a high prevalence of metabolic syndrome and clusters of its components in older adults. It is important to deepen studies on this matter, considering clinical aspects in relation to sex and healthy behavioral habits for creating public policies as well as emphasizing actions aimed at promoting self-care in all cycles of life.

ABSTRACT

Fundamento: Síndrome metabólica é um importante fator de risco cardiovascular, e sua prevalência aumenta após a menopausa. Ainda é incerto, porém, se a menopausa é fator de risco independente para a síndrome metabólica. Uma das bases fisiopatológicas para síndrome metabólica é a resistência insulínica, que pode ser calculada pelo método Homeostatic Model Assessment-Insulin Resitance (HOMA-IR), sendo pouco conhecida a relação entre resistência insulínica e menopausa. Objetivos: Avaliar a relação entre síndrome metabólica e resistência insulínica em mulheres climatéricas. Métodos: Estudo descritivo, que avaliou 150 mulheres, com idades entre 40 e 65 anos, atendidas em um ambulatório de ginecologia em um hospital terciário público, entre maio e dezembro de 2013. A amostra foi dividida em dois grupos, sendo o Grupo I com pacientes na pré-menopausa e o II com pacientes na pós-menopausa. Foi avaliada a presença de síndrome metabólica, bem como de seus componentes, além da ocorrência de resistência insulínica nos dois grupos. A associação do estado menopausal e as variáveis estudadas foi realizada com os testes Mann-Whitney, qui quadrado e exato de Fisher. O nível de significância foi de 5%. A análise estatística foi feita por meio do STATA 12.0. Resultados: A síndrome metabólica foi mais prevalente nas mulheres pós-menopausa, bem como todos seus componentes tiveram maior frequência também nesse grupo. As mulheres pós-menopausa também apresentaram maior prevalência de resistência insulínica, mas não foi observada relação estatística entre os achados. Conclusão: O estado menopausal não se associou significativamente com síndrome metabólica e resistência insulínica. A resistência insulínica foi considerada fator de risco independente para o desenvolvimento de síndrome metabólica apenas no grupo pós-menopausa


Background: Metabolic syndrome is an important cardiovascular risk factor, and its prevalence increases after menopause. However, it is still uncertain whether menopause is an independent risk factor for metabolic syndrome. One of the pathophysiological basis for metabolic syndrome is insulin resistance, which can be calculated by the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) method, and the association between insulin resistance and menopause is little known. Objective: To evaluate the association between metabolic syndrome and insulin resistance in menopausal women. Method: Descriptive study, which evaluated 150 women, aged 40 to 65, treated at a Gynecology Outpatient Clinic of a tertiary public hospital, from May to December of 2013. The sample was divided into two groups: Group I, comprising women in the premenopausal period and Group II, comprising women in the post-menopausal period. The presence of metabolic syndrome and its components were evaluated, as well as occurrence of insulin resistance in both groups. The association of menopausal status and the assessed variables was assessed using the Mann-Whitney, Chi-square and Fisher's exact tests. The significance level was set at 5%. The statistical analysis was performed using STATA 12.0. Results: Metabolic syndrome and its components were more prevalent in postmenopausal women. Postmenopausal women also had a higher prevalence of insulin resistance, but no statistical association was observed between the findings. Conclusion: The menopausal status was not significantly associated with metabolic syndrome and insulin resistance. Insulin resistance was considered an independent risk factor for the development of metabolic syndrome only in the postmenopausal group

ABSTRACT

Abstract Background: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation. Objective: The purpose of this study was to evaluate the prevalence of MetS and the clinical features associated with it in resistant and mild to moderate hypertensives. Methods: This cross-sectional study included 236 patients, (i) 129 mild to moderate hypertensive patients and (ii) 107 patients with RHTN. We measured blood pressure (BP) and adipokines levels, and performed bioelectrical impedance analysis. Microalbuminuria (MA), cardiac hypertrophy and arterial stiffness were also assessed. The significance level of alpha = 0.05 was adopted. Results: We found a MetS prevalence of 73% in resistant and 60% in mild-to-moderate hypertensive patients. In a multiple regression analysis, MA (odds ratio = 8.51; p = 0.01), leptin/adiponectin ratio (LAR) (odds ratio = 4.13; p = 0.01) and RHTN (odds ratio = 3.75; p = 0.03) were independently associated with the presence of MetS apart from potential confounders. Conclusions: Our findings suggest that both resistant and controlled hypertensive subjects have a high prevalence of MetS. In addition, MetS-related metabolic derangements may cause early renal and hormonal changes. Finally, LAR may be useful as a reliable biomarker for identifying those hypertensive subjects who are at risk for developing MetS.


Resumo Fundamentos: A síndrome metabólica (SM) é comum em pacientes hipertensos. As características clínicas e os potenciais biomarcadores da SM na presença de hipertensão e hipertensão resistente (HR) representam uma ampla área de interesse a ser investigada. Objetivo: O objetivo deste estudo foi avaliar a prevalência de SM e as características clínicas associadas à síndrome em indivíduos com hipertensão resistente e leve a moderada. Métodos: Este estudo transversal incluiu 236 pacientes, (i) 129 pacientes com hipertensão leve a moderada e (ii) 107 pacientes com HR. Medimos a pressão arterial (PA), parâmetros bioquímicos e os níveis de adipocinas dos pacientes, além de microalbuminúria (MA), hipertrofia cardíaca e rigidez arterial. Foi adotado o nível de significância de alfa 0,05. Resultados: A SM esteve presente em 73% dos pacientes com HR e 60% daqueles com hipertensão leve a moderada. Na análise de regressão múltipla, a MA (odds ratio = 8,51; p = 0,01), a razão leptina/adiponectina (RLA) (odds ratio = 4,13; p = 0,01) e a HR (odds ratio = 3,75; p = 0,03) foram independentemente associadas com a presença de SM, excluindo-se potenciais fatores de confusão. Conclusões: Nossos resultados sugerem que tanto hipertensos resistentes como hipertensos controlados apresentam alta prevalência de SM. Além disso, distúrbios metabólicos relacionados à SM podem causar alterações precoces renais e hormonais, e a RLA parece ser útil como biomarcador confiável para identificar indivíduos hipertensos em risco de desenvolverem SM.

ABSTRACT

ABSTRACT Objective: The aim of this study is to evaluate the influence of the body mass index (BMI) and the metabolic syndrome (MetS) parameters on oxidative and nitrosative stress in overweight and obese subjects. Subjects and methods: Individuals were divided into three groups: the control group (G1, n = 131) with a BMI between 20 and 24.9 kg/m2, the overweight group (G2, n = 120) with a BMI between 25 and 29.9 kg/m2 and the obese group (G3, n = 79) with a BMI ≥ 30 kg/m2. Results: G3 presented higher advanced oxidation protein products (AOPPs) in relation to G1 and G2 (p = 0.001 and p = 0.011, respectively) whereas G2 and G3 had lower levels of nitric oxide (NO) (p = 0.009 and p = 0.048, respectively) compared to G1. Adjusted for the presence of MetS to evaluate its influence, the levels of AOPPs did not differ between the groups, whereas NO remained significantly lower. Data adjusted by the BMI showed that subjects with higher triacylglycerol levels had higher AOPPs (p = 0.001) and decreased total radical-trapping antioxidant parameter/uric Acid (p = 0.036). Subjects with lower high-density lipoprotein (HDL) levels and patients with higher blood pressure showed increased AOPPs (p = 0.001 and p = 0.034, respectively) and lower NO levels (p = 0.017 and p = 0.043, respectively). Subjects who presented insulin resistance had higher AOPPs (p = 0.024). Conclusions: Nitrosative stress was related to BMI, and protein oxidation and nitrosative stress were related to metabolic changes and hypertension. MetS components were essential participants in oxidative and nitrosative stress in overweight and obese subjects.

ABSTRACT

Despite the various standard non-linear measurements used in autonomic modulation (AM) assessments usually being applied to long time-series, such analyses can sometimes be applied to shorter term series. To overcome this disadvantage, chaotic global methods were formulated by putting together heart rate variability (HRV) linear methods. Chaos provides information about vegetative function control related to cardiovascular risks. Applying this method can be useful to investigate the complexity of the health condition after resistance training protocols, as a therapeutic intervention in AM in metabolic syndrome individuals (MetS). This study aimed to compare the effects of two resistance training programs (conventional vs functional) in MetS using nonlinear analysis of AM. MetS subjects (n=50) of both sexes aged 40 to 60 years were randomly divided into two programs; a group of 12 people served as a control group. Both groups performed 30 sessions of training. AM was assessed in the chaos domain by chaotic global techniques. The main results showed that both resistance training, functional and conventional, increased chaos when compared to the control group, respectively, observed by chaotic forward parameter (CFP)1 (13.9±17.9 vs 12.8±14.4 vs -2.23±7.96; P≤0.05) and CFP3 (15.4±19.8 vs 21.9±13.2 vs -4.82±11.4; P≤0.05). In addition, 30 sessions of both resistance programs increased chaos, and non-linear analysis enabled discrimination of AM after interventions when compared to the control group.

ABSTRACT

Abstract: Background: Rosacea is a chronic facial skin disease associated with excessive inflammatory response to various triggers. Although some studies have supported the increased risk of cardiovascular diseases in rosacea, it has not been completely accepted. Objective: We aimed to investigate epicardial fat thickness and carotid intima-media thickness as cardiovascular risk predictors in rosacea patients. Methods: We conducted a cross-sectional study including 40 rosacea patients and 40 controls. Demographic data, epicardial fat thickness, carotid intima-media thickness, lipid parameters, biochemical parameters, presence of insulin resistance, and presence of metabolic syndrome of the participants were recorded. Results: Forty rosacea patients (31 female and 9 male) and 40 controls (30 female and 10 male) were enrolled in the study. Rosacea patients had significantly higher epicardial fat thickness and carotid intima-media thickness volumes than controls (P<0.001). In the multivariate logistic regression analysis, epicardial fat thickness was independently related to presence of rosacea (P<0.001, OR=13.31). In the multiple linear regression analysis, the epicardial fat thickness was independently associated with rosacea (β= 0.47, P<0.001), carotid intima-media thickness (β= 0.36, P<0.001), and systolic blood pressure (β=0.19, P=0.015) and the carotid intima-media thickness was independently associated with epicardial fat thickness (β= 0.6, P<0.001). The epicardial fat thickness levels were correlated with carotid intima-media thickness (r=0.63, P<0.001), LDL (r=0.23, P=0.037), systolic blood pressure (r=0.45, P<0.001), and diastolic blood pressure levels (r=0.37, P=0.001). The carotid intima-media thickness levels were correlated with epicardial fat thickness (r=0.63, P<0.001), systolic blood pressure (r=0.04, P<0.001), and diastolic blood pressure levels (r=0.27, P=0.016). Study limitations: The small number of participants. Conclusions: Examination and follow-up of rosacea patients for cardiovascular diseases may be recommended practices.

ABSTRACT

Antecedentes: desarrollar formas diagnósticas de fácil aplicación, buena precisión y bajo costo, con la finalidad de predecir el riesgo cardiometabólico en nuestros pacientes, nos lleva a la necesidad de identificar medidas y relaciones antropométricas que nos resulten de utilidad en su detección. Objetivo: describir la utilidad del índice de conicidad, como predictor de riesgo cardiovascular y metabólico, y compararlo con algunas de las medidas y relaciones antropométricas utilizadas con este fin. Métodos: se revisaron 80 artículos, de los cuales 51 cumplieron con los criterios de calidad esperados por los autores. La búsqueda se realizó a través de algunas de las bases de datos y de los buscadores habituales. Resultados: las características fisiológicas del tejido adiposo abdominal son significativas, e incluso, posibles determinantes del aumento de riesgo cardiometabólico asociado a la obesidad visceral. El índice de conicidad es una relación que involucra varias medidas antropométricas, como la circunferencia de la cintura, la talla y el peso corporal. Este índice ha sido utilizado para indicar el aumento de la grasa abdominal, y en la predicción del riesgo cardiovascular y metabólico. Entre los resultados de los diferentes estudios realizados, se han observado diversos criterios con respecto a su utilidad y empleo, en comparación con otras medidas e índices antropométricos, que en el mejor de los casos, en un futuro, debemos intentar esclarecer, a través de investigaciones diseñadas con este objetivo. Conclusiones: el índice de conicidad es una relación útil, para determinar la existencia de obesidad abdominal, aunque no parece ser el mejor predictor de riesgo cardiovascular y/o metabólico, al compararlo con el resto de las medidas y relaciones antropométricas utilizadas con este fin(AU)


Background: developing diagnosing forms of easy use, good precisión and low cost, with the objective of predicting the cardiometabolic risk in our patients, leads us to the task of identifying anthropometric measurements and ratios that may be useful for the risk detection. Objective: to describe the usefulness of the conicity index as a predictor of cardiovascular and metabolaic risk and compare it with some of the anthropometric measurements and ratios used to this end. Methods: eighty aritcles, 51 of which met the expected quality criteria of the authors, were reviewed. The search was made in some of the regular databases and searchers. Results: the physiological characteristics of the abdominal fatty tissue were significant and even they may be possible determinants of the increased cardiometabolic risk associated to visceral obesity. The conicity index is a ratio that involves several anthropometric measurements such as waist circumference, height and body weight. This index has been used to show increase of abdominal fat and in prediction of the cardiovascular and the metabolic risk. Among the results of the different studies, there have been observed various criteria about the usefulness and applications of the index in comparison with other anthropometric measurements and indexes; something that at the very best should be clarified in the future through research studies designed for this end. Conclusions: the conicity index is a useful ratio to determine the existence of abdominal obesity, although it does not seem to be the best predictor of the cardiovascular and/or metabolic risk when making a comparison with the rest of the anthropometric measurements and ratios that have been so far used(AU)

ABSTRACT

Summary Introduction: The purpose of this study was to evaluate the prevalence of peripheral polyneuropathy (PPN) in subjects with grade II and III obesity (Ob-II,III) and metabolic syndrome (MetS) but without diabetes and to investigate possible associated factors. Method: A cross-sectional study was performed in non-diabetic Ob-II,III,MetS patients using the Michigan Neuropathy Screening Instrument (MNSI) to assess the presence of PPN. Results: A total of 24 of 218 non-diabetic Ob-II,III,MetS patients had PPN. Based on univariate analysis, serum levels of LDL-cholesterol (p=0.046) were significantly associated with PPN, while serum triglycerides (p=0.118) and low HDL-cholesterol (p=0.057) showed a tendency toward this association. On a Poisson regression analysis, when the three possible associations were included, low HDL-cholesterol (p=0.047) remained independently associated. Conclusion: In non-diabetic Ob-II,III,MetS patients, PPN defined by the MNSI showed a high prevalence and was associated with low levels of HDL-cholesterol. In order to diagnose that complication, neurological evaluation should be performed in these patients.


Resumo Objetivo: Avaliar a prevalência da polineuropatia periférica (PNP) em indivíduos obesos graus II e III com síndrome metabólica (Ob-II,III,SM) sem diabetes e buscar possíveis fatores associados. Método: Em um estudo transversal, realizado em indivíduos Ob-II,III,SM e sem diagnóstico de diabetes, o Instrumento de Screening de Michigan (MNSI) foi utilizado para avaliar a presença de PNP. Resultados: Um total de 24 de 218 pacientes Ob-II,III,SM e sem diabetes tinham PNP. Quando observamos as associações com PNP em uma análise univariada, níveis séricos de LDL-colesterol (p=0.046) estiveram significativamente associados e houve também uma tendência à associação com níveis séricos de triglicerídeos (p=0.118) e baixo HDL-colesterol (p=0.057). Em uma análise de regressão de Poisson, quando as três possíveis associações foram incluídas, baixo HDL-colesterol (p=0.047) manteve-se independentemente associado. Conclusão: Em pacientes Ob-II,III,SM, mas sem diabetes, a PNP definida pelo MNSI tem uma prevalência elevada e está associada a baixos níveis de HDL-colesterol. Para diagnóstico dessa complicação, recomenda-se realizar o exame neurológico desses pacientes.

ABSTRACT

Resumen:El síndrome metabólico (SM) es un desorden clínico que se caracteriza por presentar obesidad abdominal, hipertensión, dislipidemia y resistencia a la insulina. El SM es un estado de inflamación crónica de bajo grado con efectos sistémicos profundos. El SM incrementa el riesgo de diabetes tipo 2 y de enfermedad cardiovascular. El riesgo para resultados adversos en la salud se incrementa sustancialmente con la acumulación de componentes del SM. En las dos últimas décadas varias organizaciones han propuesto diferentes definiciones usando diferente terminología. Varios factores de riesgo modulan la prevalencia del SM, incluyendo factores del estilo de vida como la calidad nutricional y la ausencia de actividad física. La edad, la etnia y el sexo también contribuyen a la susceptibilidad metabólica. La adiposidad visceral ectópica en exceso es fundamental en la patofisiología del SM.Un enfoque inicial en la terapia del SM incluye una combinación entre la reducción de peso, la modificación dietaria y el incremento en la actividad física, preferiblemente los tres. El tratamiento farmacológico debe considerarse para aquellas personas cuyos factores de riesgo no son reducidos adecuadamente con las medidas preventivas y los cambios en el estilo de vida.


Abstract:The metabolic syndrome (MS) is a clinical disorder characterized by abdominal obesity, hypertension, dyslipidemia and insulin resistance. The MS is a state of chronic low grade inflammation with profound systemic effects. The MS increases the risk for type 2 diabetes and cardiovascular disease. The risk for adverse health outcomes increase substantially with accumulation of components MS risk factors. Over the last two decades, various organizations have proposed different definitions, using varying terminologies. Several factors modulates the prevalence of MS including lifestyle factors such as por nutritional quality and lack of physical activity. Age, race, and sex also contribute to metabolic susceptibility. Excess ectopic and/or visceral adiposity is fundamental to the pathophysiology of MS.An initial approach in the therapy of MS include some combination among weight reduction, dietary modification, and increased physical activity, preferably all three. Pharmacological treatment should be considered for those whose risk factors are not adequately reduced with the preventive measures and lifestyle changes.
