Método indirecto para la verificación del intervalo de referencia del perfil lipídico / Indirect method for the verification of the lipid profile reference range

Introducción: La dislipidemia es uno de los problemas más frecuentes en los niños y adolescentes y su estudio es importante debido a su fuerte correlación con la enfermedad cardiovascular aterosclerótica en adultos. Muchos países desarrollaron valores de referencia nacionales investigando los lípidos séricos utilizando datos basados en la población nacional propia. Nuestro objetivo fue verificar el intervalo de referencia del perfil lipídico calculando las curvas de percentiles a través del método indirecto en nuestra población pediátrica. Materiales y métodos: Se analizaron los resultados de nuestra base de datos utilizando el método indirecto. Luego de aplicar filtros y criterios de exclusión se calcularon los percentiles 25, 50, 75, 95 y 99 para colesterol total (CT), colesterol HDL (C-HDL), colesterol no HDL (C-no-HDL), triglicéridos (TG) y colesterol LDL (C-LDL) y para el C-HDL además se calculó el percentil 10. El valor de referencia para el cambio (RCV) se utilizó para determinar si existía diferencia clínicamente significativa entre los valores de percentiles obtenidos y los utilizados en el consenso de la SAP. Resultados: No se evidenció diferencia clínicamente significativa contra los valores propuesto por la SAP, excepto para los TG para las edades 1,5,7 años en el percentil 95 y para la edad de 8 años en el percentil 75 y 95; para el C-HDL en el percentil 10 para las edades 1,16 y 17 años. Discusión: Se obtuvieron los percentiles de los lípidos y se compararon con los valores de referencia utilizados por el consenso en el que están basados las guías (AU)

Introduction: Dyslipidemia is one of the most common problems in children and adolescents and its study is important because of its strong correlation with atherosclerotic cardiovascular disease in adulthood. Many countries have developed national reference values investigating serum lipids using data based on their own national population. Our aim was to verify the lipid profile reference range by calculating percentile curves through the indirect method in our pediatric population. Materials and methods: The results of our database were analyzed using the indirect method. After applying filters and exclusion criteria, the 25th, 50th, 75th, 95th, and 99th percentiles were calculated for total cholesterol (TC), HDL cholesterol (HDL-C), non-HDL cholesterol (non-HDL-C), triglycerides (TG), and LDL cholesterol (LDL-C); for HDL-C, the 10th percentile was also calculated. The reference change values (RCV) were used to determine whether there was a clinically significant difference between the percentile values obtained and those used in the consensus of the Argentine Association of Pediatrics (SAP). Results: There was no clinically significant difference with the values proposed by the SAP, except for TG for ages 1, 5, and 7 years at the 95th percentile and for age 8 years at the 75th and 95th percentile; and for HDL-C at the 10th percentile for ages 1, 16, and 17 years. Discussion: Lipid percentiles were obtained and compared with the reference values used by the consensus on which the guidelines are based (AU)

Relación del consumo de calcio con el síndrome metabólico en adultos de la Amazonía Ecuatoriana / Relationship of calcium consumption with metabolic syndrome in adults from the Ecuadorian Amazon

Introducción. El Síndrome Metabólico (SM) comprende un conjunto de factores de riesgo cardiometabólico representado por obesidad central, dislipidemia, hipertensión arterial y glucosa alterada, se ha evidenciado que el consumo adecuado de calcio representa una disminución del riesgo para este síndrome. Objetivo. Analizar la relación entre el consumo de calcio total, de origen animal y vegetal con el SM y sus indicadores. Materiales y métodos. Estudio transversal de eje correlacional, con una muestra de 100 adultos de la región amazónica ecuatoriana, durante el último trimestre del 2020. La ingesta dietética de calcio se determinó mediante un recordatorio de 24 horas y el SM según los criterios de Adult Treatment Panel-IV (ATP-IV). Resultados. La población estuvo conformada por adultos maduros (40 a 60 años) que evidenciaron una ingesta de calcio deficiente (182,50 mg y 228,60 mg en mujeres y hombres respectivamente). Se evidenció, además, una relación directamente proporcional entre la circunferencia abdominal (r=0,391 ­ p=0,000), presión arterial sistólica (r=0,290 ­ p=0,000) y glucosa en ayuno (r=0,326 ­ p=0,000) con la edad. La ingesta de calcio total se relacionó positivamente con los triglicéridos, (r=0,221 ­ p=0,027). Conclusiones. La ingesta dietética de calcio en ambos sexos no alcanza el requerimiento diario y se relaciona positivamente con los triglicéridos(AU)

Introduction. The Metabolic Syndrome (MS) comprises a set of cardiometabolic risk factors represented by central obesity, dyslipidemia, high blood pressure and altered glucose, it has been shown that adequate calcium intake represents a decreased risk for this syndrome. Objective. To analyze the relationship between the consumption of total calcium, animal and vegetable origin, with MS and its indicators. Materials and methods. Cross-sectional study of correlational axis, with a sample of 100 adults from the Ecuadorian Amazon region, during the last quarter of 2020. Dietary calcium intake was determined through a 24-hour recall and the diagnosis of MS according to the Adult Treatment Panel- IV (ATP-IV) criteria. Results. The population consisted of mature adults (40 to 60 years) who showed a deficient calcium intake in both sexes (182.50 mg and 228.60 mg in women and men respectively). There is also evidence of a directly proportional relationship between abdominal circumference (r=0.391 - p=0.000), systolic blood pressure (r=0.290 - p=0.000) and fasting glucose (r=0.326 - p=0.000) with age. Total calcium intake was positively related to triglycerides (r=0.221 ­ p=0.027). Conclusions. Calcium dietary intake in both sexes does not reach the daily requirement and is positively related to triglycerides(AU)

Effects of passion fruit (Passiflora tenuifila Killip) intake on eutrophic and obese subjects: Lipidomic approach

Obesity and overweight result in metabolic changes that build up as risk factors for the development of the main non-communicable diseases. Among these alterations, dyslipidemia is an important risk factor for cardiovascular diseases (CDV) and is expressed in elevated plasma levels of triacylglycerols, cholesterol, and low-density-lipoprotein (LDL, VLDL) and decreased plasma levels of high-density lipoprotein (HDL). Passiflora tenuifila Killip is a native passion fruit species of the Brazilian Midwest region and is a good source of proanthocyanidins and dietary fibers. Proanthocyanidins are a class of phenolic compounds that are attributed with improving lipoprotein profile properties, translated as improved LDL/HDL ratio. Fibers are fermented by the gut microbiota and produce short-chain fatty acids (SCFA), also involved in the regulation of energetic metabolism.. A 30-consecutive-day-long intervention with lyophilized P. tenuifila flour was performed in eutrophic and obese subjects. Passion fruit ingestion increased fecal production of acetate, key SCFA in the modulation of lipid metabolism; reduced body fat percentage in all subjects; and reduced total cholesterol (TC) of subjects who presented basal CT > 130 mg/dL. After the intervention, plasma lipidomic analysis detected 44 statistically significant lipids, regardless of BMI. Considering the study population with altered TC, reduced levels of glycerophospholipids were observed, a lipid class studied for their involvement in CVD. The intake of P. tenuifila contributed to the improvement in cardiovascular risk markers and acts on lipid metabolism. These effects may be due to synergic action between the bioactive compounds in the fruit. Still, other studies are necessary to identify mechanisms related to the action of bioactives of P. tenuifila, which can be better directed by this lipidomic approach

A obesidade e o sobrepeso são preocupações resultam em alterações metabólicas que se acumulam como fatores de risco para o desenvolvimento a longo prazo das principais doenças crônicas não transmissíveis. Dentre essas alterações, a dislipidemia um importante fator de risco para doenças cardiovasculares (DCV), expressa em níveis plasmáticos elevados de triacilgliceróis, colesterol e das lipoproteínas de baixa densidade (VLDL, LDL), e níveis diminuídos da lipoproteína de alta densidade (HDL). Passiflora tenuifila Killip é uma espécie de maracujá nativa da região Centro-Oeste brasileira, e é uma boa fonte de proantocianidinas e fibras alimentares. As proantocianidinas são compostos fenólicos com reportados efeitos na melhora do perfil de lipoproteínas, traduzida como a relação LDL/HDL. As fibras são fermentadas pela microbiota intestinal e produzem ácidos graxos de cadeia curta (AGCC), metabólitos também envolvidos na regulação do metabolismo energético.. Assim, a lipidômica não-target é aplicada como ferramenta exploratória neste estudo: uma intervenção de 30 dias consecutivos de ingestão de P. tenuifila na forma de farinha liofilizada em indivíduos eutróficos e obesos. O consumo do maracujá promoveu aumento da produção fecal de acetato, AGCC importante na modulação do metabolismo lipídico; a redução do percentual de gordura corporal em todos os indivíduos; e redução do colesterol total (CT) para os indivíduos com CT > 130 mg/dL. A análise lipidômica do plasma detectou 44 lipídios estatisticamente relevantes, independentemente do IMC, após a intervenção. Considerando a população do estudo com CT alterado, foi observada uma redução de glicerofosfolipídios, classe de lipídios estudada pelo seu envolvimento em DCV. Assim, a ingestão de P. tenuifila contribui para a melhora nos marcadores de risco cardiovascular e atua no metabolismo lipídico. Estes efeitos podem ser decorrentes de sinergia entre os diversos compostos bioativos do fruto. Ainda, outros estudos são necessários para identificar mecanismos relacionados a ação dos bioativos da P. tenuifila e estes podem ser mais bem direcionados pela lipidômica

Major cardiovascular risk factors and serious mental disorders, a double-edged sword: literature review

Background. The burden of mental disorders continues to grow with significant impacts on health. Their prevalence is higher in patients presenting cardiovascular risk factors.This review takes stock of the frequency, the mechanisms, and the implications of major cardiovascular risk factors in patients with serious mental disorders. Methods. A literature search was done in PubMed from 1980 to 2021 using various combinations of Mesh termslike tobacco, diabetes mellitus, hypertension, dyslipidemia, major depressive disorder, bipolar disorder, schizophrenia. Results. People with serious mental disordershave a greater prevalence of major cardiovascular risk factors compared to the general population. Conversely, people with cardiovascular diseases more frequently suffer from serious mental disorders. More specifically, we note that 45 to 88% of patients suffering from schizophrenia are tobacco users, Depression is reported to be 3 times higher in hypertensives than in non-hypertensives while around 19% of type 2 diabetic patients suffer from major depressive disorderwhich is 3 times greater than in the general population, and the prevalence of dyslipidemia among persons with severe and persistent mental illness is higher than the prevalence in the general population and ranges from 25% to 70%. The concomitant presence of these different pathologies can be explained either by their intertwined pathophysiological mechanisms, or by the side effects of the various medications taken in the context of these chronic diseases. Conclusion. The predisposing factors for the coexistence of mental illnesses and cardiovascular diseases are often entangled. It would be interesting to carry out more studies to elucidate precisely the different pathophysiological mechanisms of these diseases.

Contexte. La prévalence des maladies mentales est plus élevée chez les patients présentant des facteurs de risque cardiovasculaire. Cette revue fait le point sur la fréquence, les mécanismes et les implications des facteurs de risque cardiovasculaire majeurs chez les patients atteints de pathologies psychiatriques graves. Méthodologie. Une recherche documentaire a été effectuée dans PubMed de 1980 à 2021 en utilisant diverses combinaisons de termes MeSH comme tabac, diabète, hypertension, dyslipidémie, trouble dépressif majeur, trouble bipolaire, schizophrénie. Résultats. Les personnes atteintes de maladie mentales graves ont une plus grande prévalence de facteurs de risque cardiovasculaire majeurs comparé à la population générale. A l'inverse, les personnes atteintes de maladies cardiovasculaires souffrent plus fréquemment de troubles mentaux graves. Plus précisément, on note que 45 à 88% des patients souffrant de schizophrénie consomment du tabac. La dépression serait 3 fois plus élevée chez les hypertendus que chez les non hypertendus. Par ailleurs, environ 19% des patients diabétiques de type 2 souffrent d'un trouble dépressif majeur ce qui est 3 fois plus élevée que dans la population générale. La prévalence des dyslipidémies chez les personnes atteintes d'une maladie mentale grave est supérieure à la prévalence dans la population générale et varie de 25 % à 70 %. La présence concomitante de ces différentes pathologies s'explique soit par leurs mécanismes physiopathologiques imbriqués, soit par les effets secondaires des différents médicaments pris dans le cadre de ces maladies chroniques. Conclusion. Les facteurs prédisposant à la coexistence des maladies mentales et des maladies cardiovasculaires sont souvent intriqués. Il serait intéressant de mener plus d'études pour élucider précisément les différents mécanismes physiopathologiques de ces maladies.

Profil glucido-lipidique et risque cardiovasculaire chez les diabétiques de type 2 / Carbohydrate and lipid profile associated with cardiovascular risk in type 2 diabetics

Introduction-Le diabète est un véritable problème de santé publique du fait de ses nombreuses complications potentielles, notamment cardiovasculaires. Notre objectif était de décrire le profil clinico-biologique chez une population de diabé tique type 2 et d'étudier la relation entre l'équilibre glycémique et les anomalies lipidiques avec les complications micro et macroangiopathiques. Matériels et méthodes -Nous avons mené une étude rétrospective portant sur 341 pa tients diabétiques type 2.Les données ont été analysées par le logiciel IBM® SPSS statis tics 20.0. Seules, les associations significatives (p ≤ 5%) étaient retenues. Résultats - quatre-vingt deux pourcent et demi des patients ont un taux d'HbA1c ≥7 %. Plus de 60 % ont une dyslipidémie. Cinquante deux pourcent des patients ont un taux du LDLc ≤ 1 g/l, et 64,4 % ont un taux du Non-HDLc >1g/l. Environ 66 % des patients ont une hypertension artérielle. quarante pourcent des patients ont présenté une macroangio pathie et 66,8 % une microangiopathie (p=0,0001). L'analyse par régression logistique, a montré que l'HbA1c est le paramètre biologique le plus associé aux complications macroangiopathiques (p=0,008), alors que pour les complications micro-angiopathiques, l'HTA était le seul facteur associé (p = 0,03). Pour la cardiopathie ischémique, la dyslipi démie et l'HTA étaient les facteurs les plus associés. Conclusion -Notre étude a montré une fréquence élevée des complications micro et macroangiopathiques et des anomalies lipidiques, ainsi qu'un très mauvais équilibre glycémique. L'HbA1c, la dyslipidémie et l'HTA sont les facteurs les plus associés au risque cardiovasculaire.

Background-Diabetes is a real health public problem because of its many potential complications, particularly the cardiovascular ones.The aim of this work was to describe the clinical and biological profile in type 2 diabetic population, then to study the relationship between glycemic control and lipid abnormalities with micro and macro vascular complications. Methods - It was about a retrospective study of 341 type 2 diabetes patients' with an average age of 60.1 ± 11.71 years.The IBM® SPSS statistics 20.0 software was used for analyzing data. Only significant associations (p ≤ 5%) were retained. Results -An HbA1c level ≥7% was observed in 82,5% of patients, More than 60% have dyslipidemia. 52,8% of them have an LDLc level ≤ 1 g/l, and 64,4% have a Non-HDLc level >1g/l. Sixty-six percent of patients have high blood pressure. The macrovascular disorders were observed on 30,9% of patients and microvascular ones on 66,8% of them (p = 0.0001).The logistic regression analysis showed that HbA1c was the most significant biological parameter (p=0,008). while for micro-vascular complications, high blood pressure was the only associated factor (p = 0.03). For ischemic heart disease, dyslipidemia and high blood pressure were the most associated factors. Conclusion - this study showed a high frequency of micro and macrovascular complications, lipid abnormalities and a very poor glycemic control. The elevation of HbA1c level, the high blood pressure and dyslipidemia are the most associated factors with a high cardiovascular risk.

Estresse percebido em mulheres com síndrome metabólica: um estudo transversal / Perceived stress in women with metabolic syndrome: a cross-sectional study / Estrés percibido en mujeres con síndrome metabólico: un estudio transversal

Introdução: o estresse percebido foi sugerido como um fator de risco para o desenvolvimento da Síndrome Metabólica (SM). No entanto, pouco se sabe desta associação entre mulheres. Objetivo: avaliar o estresse percebido em mulheres com SM. Materiais e Métodos: estudo transversal, a partir do recorte de um ensaio clínico não-randomizado, com pacientes de um centro de saúde público (RBR-43K52N). A variável de desfecho foi a SM, utilizando os critérios do NCEP/ATPIII. Foram coletados dados sociodemográficos, antropométricos, bioquímicos, hemodinâmicos e aplicação da PSS. Resultados: A amostra constituiu-se de 75 mulheres acometidas por SM (47,69±8,15 anos de idade; 155,65±0,07 cm; 82,43±17,79 kg; IMC de 33,54±7,28). Encontrou-se valores elevados de RCQ entre as mulheres estressadas e não-estressadas. A pontuação média da PSS foi de 27,73±9,17. Nos agrupamentos, verificou-se diferença significativa para PSS entre as mulheres estressadas e não-estressadas (35,24±5,22 e 20,42±5,53, respectivamente; p=0,001). Observou-se também que mulheres estressadas tinham níveis mais elevados de triglicerídeos e níveis mais baixos de HDL-c quando comparadas com mulheres não estressadas, embora sem diferença estatística. Discussões: Os achados sugerem que as mulheres categorizadas como estressadas tinham maior pontuação da PSS, níveis mais elevados de triglicerídeos e níveis mais baixos de HDL-c quando comparadas com mulheres não estressadas. Conclusões: a pontuação da PSS foi significativamente maior entre mulheres com parâmetros lipídicos da SM alterados, com menores níveis de HDL- e aumento de triglicerídeos.

Introduction: Perceived stress has been suggested as a risk factor for the development of Metabolic Syndrome (MS). However, little is known about this association among women. Objective: to evaluate perceived stress in women with Metabolic Syndrome (MS). Materials and Methods: cross-sectional study, based on a non-randomized clinical trial, with patients from a public health center (RBR-43K52N). The outcome variable was MS, using the NCEP/ATPIII criteria. Sociodemographic, anthropometric, biochemical, hemodynamic data and PSS application were collected. Results: The sample consisted of 75 women affected by MetS (47.69± 8.15 years old; 155.65±0.07 cm; 82.43±17.79 kg; BMI of 33.96±6 ,42). High WHR values were found among stressed and non-stressed women. The average PSS score was 27.73±9.17. In the groups, there was a significant difference for PSS between stressed and non-stressed women (35.24±5.22 and 20.42±5.53, respectively; p=0.001). It was also observed that stressed women had higher levels of triglycerides and lower levels of HDL-c when compared to non-stressed women, although without statistical difference. Discussions: The findings suggest that women categorized as stressed had higher PSS scores, higher levels of triglycerides and lower levels of HDL-c when compared to non-stressed women. Conclusions: the PSS score was significantly higher among women with altered MS lipid parameters, with lower levels of HDL- and increased triglycerides.

Riscos de infecção por SARS-CoV-2 e COVID-19 em mulheres com síndrome dos ovários policísticos / Risks of SARS-CoV-2 and COVID-19 infection in women with polycystic ovary syndrome

Esta revisão narrativa teve como objetivo avaliar possíveis riscos da associação entre a infecção por SARS-CoV-2 (causa da COVID-19) e as características metabólicas e endócrinas frequentemente encontradas em mulheres com a síndrome dos ovários policísticos (SOP). A COVID-19 é mais grave em indivíduos com obesidade, diabetes mellitus, dislipidemia e hipertensão arterial. Como essas condições são comorbidades comumente associadas à SOP, foi hipotetizado que mulheres com SOP teriam maior risco de adquirir COVID-19 e desenvolver formas clínicas mais graves da doença. Considerando vários estudos epidemiológicos, a presente revisão mostra que mulheres com SOP têm risco 28% a 50% maior de serem infectadas pelo vírus SARS-CoV-2 em todas as idades e que, nessas mulheres, a COVID-19 está associada a maiores taxas de hospitalização, morbidade e mortalidade, especialmente naquelas com alterações no metabolismo de carboidratos e lipídios, hiperandrogenemia e aumento do tecido adiposo visceral. Os mecanismos que explicam o maior risco de infecção por COVID-19 em mulheres com SOP são considerados.(AU)

Relación de riesgo entre dislipidemia y COVID-19 / Risk relationship between dyslipemia and COVID-19

La presencia de dislipidemia en pacientes con la COVID-19 parece agravar el curso clínico de la enfermedad. En esta revisión bibliográfica se describen los principales mecanismos que las vinculan y sus implicaciones en el tratamiento de los pacientes afectados. Para realizar este trabajo se efectuó una búsqueda bibliográfica en bases de datos, tales como Google académico, SciELO, Annual Reviews y PMC. Los descriptores analizados fueron COVID-19, SARS-CoV-2, dislipidemia, LDL-colesterol, HDL-colesterol, triglicéridos, hipercolesterolemia y lipoproteínas VLDL. Se revisaron preferentemente artículos de revistas arbitradas por pares y disponibles a texto completo, publicados en inglés y español. A pesar de las controversias, la dislipidemia es un factor de riesgo de pronóstico desfavorable en afectados con la COVID-19 y el tratamiento para los pacientes con esa condición desfavorable mejora dicho pronóstico.

The presence of dyslipemia in patients with COVID-19 seems to increase the clinical course of the disease. In this literature review the main mechanisms that link them and their implications in the treatment of the affected patients are described. To carry out this work a literature search was made in databases, such as academic Google, SciELO, Annual Reviews and PMC. The analyzed describers were COVID-19, SARS-CoV-2, dyslipemia, LDL-cholesterol, HDL-cholesterol, triglycerides, hypercholesterolemia and VLDL lipoproteins. Articles of magazines arbitrated by pairs and available to complete text, published in English and Spanish were preferably revised. In spite of the controversies, dyslipemia is a risk factor of unfavorable prognosis in patients affected with COVID-19 and the treatment for the patients with that unfavourable condition improve this prognosis.

Criterios predictores en el diagnóstico de la hipercolesterolemia familiar / Predictive criteria in the diagnosis of familial hypercholesterolemia

Introducción: La hipercolesterolemia familiar es una enfermedad con alta prevalencia, no tratada acorta la esperanza de vida, por lo que el diagnóstico a edades tempranas resulta fundamental. Las pruebas genéticas constituyen el gold standard para el diagnóstico de hipercolesterolemia familiar, sin embargo, la no disponibilidad del test genético no debe constituir un impedimento para la adecuada conducta en estos casos. Objetivo: Identificar criterios clínicos predictores en el diagnóstico por pesquisa de la hipercolesterolemia familiar. Métodos: Se realizó un estudio descriptivo prospectivo a partir de una muestra de 393 pacientes (casos índices) de HF en el Hospital Clínico Quirúrgico Hermanos Ameijeiras; durante el período 2008-2018. Resultados: En la pesquisa familiar fueron identificados 177 (15,66 por ciento) nuevos casos de hipercolesterolemia familiar, de ellos se clasifican como casos positivos 35 (19,77 por ciento), casos probables 58 (32,77 por ciento) y casos posibles 84 (47,46 por ciento). Las categorías del estrato Make early diagnosis to prevent early death MEDPED y la edad del caso índice resultaron ser las variables clínicas de interés con mayor probabilidad para identificar nuevos casos de hipercolesterolemia familiar. Conclusiones: los criterios clínicos estandarizados de la escala make early diagnosis to prevent early death P y la edad del caso índice resultaron ser indicadores predictivos de gran valor para identificar y estratificar casos con variantes fenotípicas de hipercolesterolemia familiar(AU)

Introduction: Familial hypercholesterolemia is a disease with high prevalence; it shortens life expectancy if it is not treated, so early diagnosis is essential. Genetic tests are the gold standard for the diagnosis of familial hypercholesterolemia, however, the unavailability of the genetic test should not be an obstacle to proper conduct in these cases. Objective: To identify predictive clinical criteria in the diagnosis by screening of familial hypercholesterolemia. Methods: A prospective descriptive study was carried out from a sample of 393 patients (index cases) of FH at Hermanos Ameijeiras Surgical Clinical Hospital from 2008 to 2018. Results: In the family investigation, 177 (15.66 percent) new cases of familial hypercholesterolemia were identified, 35 of them (19.77 percent) are classified as positive cases, 58 (32.77 percent) as probable cases and 84 as possible cases (47.46 percent)The stratum categories of Make Early Diagnosis to Prevent Early Death (MEDPED) and the age of the index case turned out to be the clinical variables of interest with the greatest probability to identify new cases of familial hypercholesterolemia. Conclusions: The standardized clinical criteria of the make early diagnosis to prevent early death P scale and the age of the index case turned out to be highly valuable predictive indicators to identify and stratify cases with phenotypic variants of familial hypercholesterolemia(AU)

Anthropometric markers of abdominal adiposity and its relation to dyslipidemia and insulin resistance among overweight/obese schoolchildren and adolescents / Marcadores antropométricos de adiposidade abdominal e sua relação com dislipidemia e resistência à insulina em escolares e adolescentes com sobrepeso/obesidade

Objective: to assess the relationship between anthropometric indicators and laboratorial markers of cardiovascular risk in overweight/obese children and adolescents, in order to verify whether any anthropometric indicator has a better potential for use in screening cardiovascular risk in the population. Method: retrospective cross-sectional study enrolling 237 individuals aged 7 to 18 years. Body mass index (BMI), waist circumference (WC), waist circumference/height index (WC/H), glucose, HOMA-IR, total cholesterol (TC), LDL, HDL, triglycerides and TC/HDL and LDL/HDL indexes were obtained. Associations between anthropometric and laboratory markers were tested in contingency tables using the chi-square test. Correlations were tested by Spearman's correlation. Results: higher WC (Freedman cutoffs) was associated with lower levels of HDL and higher score in the TC/HDL and LDL/HDL indexes, but, using +2 z-scores as the cutoff, there were associations with low HDL and higher HOMA-IR. WC/H indicator (0.5 cutoff) was not associated with any of the outcomes, but, using +2 z-scores, an association was found with HOMA-IR. Z-scores of WC, WC/H and BMI showed positive correlation with HOMA-IR, TC/HDL and HOMA-IR, respectively. Negative correlations were found between WC and WC/H z-scores with HDL. WC and WC/H z-score were related to changes in HDL and HOMA-IR. Conclusions: there seems to be an advantage in using WC alone as a possible predictor of dyslipidemia and insulin resistance in children and adolescents. It is not possible to state that WC, WC/H or BMI measurements differ in their abilities to identify Brazilian children and adolescents with risk factors for cardiovascular diseases (AU)

Objetivo: avaliar a relação entre indicadores antropométricos e marcadores laboratoriais de risco cardiovascular em crianças e adolescentes com sobrepeso / obesidade, a fim de verificar se algum indicador antropométrico tem melhor potencial para uso no rastreamento de risco cardiovascular na população. Método: estudo transversal retrospectivo com 237 indivíduos com idades entre 7 e 18 anos. Índice de massa corporal (IMC), circunferência da cintura (CC), índice de circunferência da cintura / altura (CC / H), glicose, HOMA-IR, colesterol total (CT), LDL, HDL, triglicerídeos e índices CT/HDL e LDL/HDL foram obtidos. As associações entre marcadores antropométricos e laboratoriais foram testadas em tabelas de contingência por meio do teste do qui-quadrado. As correlações foram testadas pela correlação de Spearman. Resultados: CC mais elevado (pontos de corte de Freedman) foi associado a níveis mais baixos de HDL e maior pontuação nos índices TC/HDL e LDL/HDL, mas, usando +2 escores z como ponto de corte, houve associações com HDL baixo e HOMA-IR mais alto. O indicador CC/H (0,5 ponto de corte) não foi associado a nenhum dos desfechos, mas, usando +2 escores z, foi encontrada associação com o HOMA-IR. Os escores Z de CC, CC/E e IMC mostraram correlação positiva com HOMA-IR, TC/HDL e HOMA-IR, respectivamente. Correlações negativas foram encontradas entre CC e escores z de CC/H com HDL. CC e escore z de CC/H foram relacionados a mudanças em HDL e HOMA-IR. Conclusões: parece haver vantagem em usar a CC isoladamente como possível preditor de dislipidemia e resistência à insulina em crianças e adolescentes. Não é possível afirmar que as medidas de CC, CC/E ou IMC diferem na capacidade de identificar crianças e adolescentes brasileiros com fatores de risco para doenças cardiovasculares (AU)

High Dilution in Dyslipidemia treatment in Dogs and Rabbits

Excess weight causes disorders in locomotor, cardiorespiratory and reproductive systems and increases the incidence of endocrinopathies, as well it can often cause dyslipidemias, leading to atherosclerosis. Aims: Report the evolution of homeopathic treatment in 4 overweight patients, being 2 female dogs and 2 female rabbits with hypertriglyceridemia, analyzing the values in biochemical test. Methodology:Homeopathic treatment was chosen, based on the principle of similitude, using Cholesterinum due to its action to decrease cholesterol and triglyceride levels. Results:The same protocol was made for all of the four patients, included 2 globules of Cholesterinum 30CH direct in its mouth, every 12 hours for 30 days. The first dog attended on 01/09/2019, and presented 328 mg/dL of triglycerides, decreasing this level to 132 mg/dL after just one-monthtreatment. The second dog attended on 04/05/2019, presented higher hypertriglyceridemia with 617 mg/dL that decreased to 259 mg/dL. Likewise, on 02/06/2019, the first rabbit attended, presented 445mg/dL of triglycerides, which were reduced to 337 mg/dL, while the second rabbit, on 06/27/2019, presented 372 mg/dL of triglycerides, decreasing to 274 mg/dL after. Although the values of cholesterol in all patients were in agreement with the reference, the treatment still proved improvements. In the beginning of the treatment, the first dog showed 207 mg/dL of cholesterol and in the end, it reduced to 170 mg/dL, as well with the second dog with 218 mg/dL in the beginning and 200 mg/dL after. Regarding rabbits, the first one presented an initialvalue of 60 mg/dL, which decreased to 52 mg/dL, while the second started with 57 mg/dL and went to 41 mg/dL. Conventionally, Bezafibrate is indicated as a lipid-lowering agent, but it is contraindicated in patients with liver or kidney failure, vesicular diseases,and for pregnant or lactating. Conclusion:Dyslipidemia can be controlled with High dilution. (The exposed information is consented by the tutors)

Interferência de medicamentos na avaliação do perfil lipídico: uma revisão de literatura / Interference of medications in the evaluation of the lipid profile: a review of the literature

A estrita relação entre doenças cardiovasculares e dislipidemias exige o monitoramento periódico do perfil lipídico através de dosagens séricas de colesterol total, triglicérides, colesterol da lipoproteína de baixa densidade (c-LDL) e colesterol da lipoproteína de alta densidade (c-HDL). Contudo, esses testes laboratoriais estão sujeitos à interferência medicamentosa in vivo e in vitro. O objetivo desta revisão da literatura foi disponibilizar os principais medicamentos que podem interferir nos exames de avaliação do perfil lipídico, com seus respectivos mecanismos de interferência in vivo ou in vitro. Alguns fármacos podem causar como reação adversa o aumento dos níveis de c-LDL e triglicérides, ou a redução dos níveis de c-HDL, o que está associado a um maior risco de eventos cardiovasculares. Por outro lado, outros fármacos podem reduzir os níveis de c-LDL e triglicérides, ou aumentar os níveis de c-HDL. Alguns medicamentos ainda podem interferir in vitro na dosagem dos biomarcadores de avaliação do perfil lipídico. O monitoramento e diagnóstico das dislipidemias devem levar em consideração estas interferências medicamentosas, já que a interpretação equivocada dos exames laboratoriais pode resultar em tratamento desnecessário ou falta de tratamento farmacológico, gastos desnecessários e prejuízo na qualidade de vida do paciente.

The strict relationship between cardiovascular disease and dyslipidemia requires periodic monitoring of the lipid profile through serum measurements of total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c). However, these laboratory tests are subject to drug interference in vivo and in vitro. The purpose of this literature review was to make available the main drugs that can interfere with lipid profile assessment tests, with their respective in vivo or in vitro interference mechanisms. Some drugs can cause as adverse reaction the increase of LDL-c and triglycerides levels, or the reduction of HDL-c levels, which is associated with a greater risk of cardiovascular events. On the other hand, other drugs can reduce LDL-c and triglycerides levels, or increase HDL-c levels. Some medications can still interfere in vitro in the dosage of biomarkers to assess the lipid profile. The monitoring and diagnosis of dyslipidemia should take into account these drug interferences, since the misinterpretation of laboratory tests may result in unnecessary treatment or lack of pharmacological treatment, unnecessary expenses and damage to the patient's quality of life.

Asociación entre enfermedades cardiometabólicas y depresión en un hospital de referencia peruano / Association between cardiometabolic diseases and depression in a Peruvian reference hospital

INTRODUCCIÓN: Se ha postulado la relación entre la presencia de enfermedades cardiometabólicas con problemas de salud mental, en particular la depresión. OBJETIVOS: Determinar la asociación entre la presencia de enfermedades cardiometabólicas y la presencia de sintomatología depresiva evaluada mediante el cuestionario PHQ-9 en pacientes atendidos en consultorios externos de medicina interna del Hospital Nacional Hipólito Unanue. METODOLOGÍA: Estudio observacional, analítico, transversal. Se definió enfermedad cardiometabólica como la presencia de diabetes mellitus, hipertensión arterial, dislipidemia, y/u obesidad. Se utilizó el cuestionario PHQ-9 para evaluar la presencia de síntomas sugerentes de depresión. Se evaluó la asociación cruda y ajustada a posibles confusores. Para el análisis multivariado se utilizó un modelo de regresión de Poisson para hallar razones de prevalencia con sus respectivos intervalos de confianza al 95%. Se consideró un p<0,05 como estadísticamente significativo. Resultados: Se incluyeron 252 pacientes, de los que 205 (81,4%) presentaron enfermedades cardiometabólicas y 181 (71,9%) presentaron síntomas consistentes con algún grado de depresión. La presencia de enfermedades cardiometabólicas se asoció a síntomas depresivos tanto en el análisis crudo (RPc 1,43; IC 95% 1,08-1,89; p=0,012) como en el ajustado (RPa 1,31; IC 95% 1,00-1,71; p=0,048). Adicionalmente se encontró asociación entre el sexo femenino y sintomatología depresiva (RPa 1,35; IC 95% 1,11-1,63; p=0,002). CONCLUSIONES: La presencia de enfermedades cardiometabólicas se asoció con la presencia de síntomas depresivos en pacientes atendidos en la consulta externa de medicina interna. El abordaje de la salud mental debe ser parte integral del manejo multidisciplinario del paciente con enfermedad cardiometabólica.

INTRODUCTION: It has been postulated the relationship between presence of cardiometabolic diseases with mental health problems, particularly depression. Objectives: To determine the association between cardiometabolic diseases and presence of depressive symptoms, evaluated by PHQ-9 questionnaire, in patients attended at the outpatient clinic of internal medicine service at Hospital Nacional Hipolito Unanue. METHODS: Observational analytical cross-sectional study. Cardiometabolic disease was defined as the presence of diabetes mellitus, high blood pressure, dyslipidemia, and/or obesity. The PHQ-9 questionnaire was used to evaluate the presence of symptoms suggestive of depression. The association was evaluated crude and adjusted for possible confounders. For the multivariate analysis, a Poisson regression model was used to find prevalence ratios with their respective 95% confidence intervals. A p<0.05 was considered statistically significant. RESULTS: 252 patients were included, of which 205 (81,4%) presented cardiometabolic diseases and 181 (71,9%) presented symptoms consistent with some grade of depression. The presence of cardiometabolic diseases was associated with depressive symptoms both in the crude analysis (PRc 1.43; CI 95% 1.08-1.89; p=0.012) and in the adjusted one (PRa 1.31; CI 95% 1.00-1.71; p=0.048). Additionally, an association was found between female sex and depressive symptoms (PRa 1,35; CI 95% 1,11-1,63; p=0,002). CONCLUSIONS: The presence of cardiometabolic diseases was associated with the presence of depressive symptoms in patients seen at the outpatient clinic of internal medicine. The mental health approach should be an integral part of the multidisciplinary management for the patient with cardiometabolic disease.

Overview of Cardiovascular Disease Risk Factors in Adults in São Paulo, Brazil: Prevalence and Associated Factors in 2008 and 2015

Abstract Background Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in Brazil. Objective To provide population-based data on prevalence and factors associated with CVD risk factors. Methods Individuals aged ≥20 years from two editions of the cross-sectional Health Survey of São Paulo focusing on Nutrition (ISA-Nutrition), performed in Sao Paulo city in 2008 (n=590) and 2015 (n=610), were evaluated for: obesity, central obesity, waist/height ratio, high blood pressure (HBP), dyslipidemia, diabetes, and number of CVD risk factors ≥3. Prevalence was estimated according to complex survey procedures. Factors associated with cardiovascular risk factors were assessed using logistic regression, with statistical significance of p<0.05. Results Obesity and older age were associated with higher odds of all cardiovascular risk factors investigated, except for dyslipidemia. HBP was positively associated with being Black/Brown and negatively associated with being physicaly active in leisure time. Women were more likely to have increased adiposity indicators and three or more cardiovascular risk factors than men. Those with higher education had lower chances of having diabetes, HBP and dyslipidemia, and those with higher income had higher chances of having three or more risk factors. Former smokers had higher odds of diabetes, obesity, and high waist/height ratio, and smokers had higher odds of high non-HDL cholesterol levels. From 2008 to 2015, there was an increase (p<0.001) in the prevalence of diabetes (6.9% to 17.3%), HBP (31.9% to 41.8%), dyslipidemia (51.3% to 67.6%), and number of CVD risk factors ≥3 (18.9% to 34.1%). Conclusion This study shows increasing prevalence of CVD risk factors in adult population in Sao Paulo and may support the definition of target groups and priority actions on CVD prevention and treatment.

Lifestyle Intervention in Reducing Cardiometabolic Risk Factors in Students with Dyslipidemia and Abdominal Obesity: A Randomized Study

Abstract Background The long incubation periods of cardiovascular diseases offer opportunities for controlling risk factors. In addition, preventive interventions in childhood are more likely to succeed because lifestyle habits become ingrained as they are repeated. Objective To investigate the effects of recreational physical activities, in combination or not with a qualitative nutritional counseling, in cardiometabolic risk factors of students with dyslipidemia and abdominal obesity. Methods Students (8-14 years old) were randomly divided into three groups (n=23 each): i ) Control; ii ) PANC, students undergoing Physical Activity and Nutritional Counseling, and iii ) PA, students submitted to Physical Activity, only. Blood samples (12-h fasting) were collected for biochemical analysis and anthropometric markers were also assessed. Two-Way RM-ANOVA and Holm-Sidak's test, and Friedman ANOVA on Ranks and Dunn's test were applied. P ≤ 0.05 was considered significant. Effect sizes were evaluated by Hedges' g and Cliff's δ for normal and non-Gaussian data, respectively. Results Compared to the control group and to baseline values, both interventions caused significant average reductions in total cholesterol (11%; p <0.001), LDL-c (19%; p=0.002), and non-HDL-c (19%; p=0.003). Furthermore, students in the PANC group also experienced a significant decrease in body fat compared to baseline (p=0.005) and to control (5.2%; g=0.541). Conclusions The proposed strategies were effective to reduce cardiometabolic risk factors in children and adolescents. The low cost of these interventions allows the implementation of health care programs in schools to improve the students' quality of life.

Xantomas tuberosos en un paciente pediátrico: la clave en el diagnóstico precoz de una patología grave y poco frecuente / Tuberous xanthomas in a pediatric patient: a clue to the early diagnosis of a severe and infrequent disease

Los xantomas cutáneos reflejan el depósito de lípidos en la piel y pueden ser la única manifestación temprana de dislipidemias de inicio en la infancia. Las características y distribución de los xantomas orientan a la patología de base; los xantomas tuberosos tienen una fuerte asociación con la hipercolesterolemia homocigota familiar, una patología muy infrecuente. Su detección temprana otorga una ventana terapéutica para prevenir la ateroesclerosis acelerada y la mortalidad. Se presenta el caso de una paciente que comenzó a los dos años con xantomas tuberosos, que fueron la clave diagnóstica para identificar la hipercolesterolemia homocigota familiar subyacente.

Cutaneous xanthomas reflect lipid deposition on the skin and may be the only early manifestation of a childhoodonset dyslipidemia. Characteristics and distribution of the xanthomas signalize the underlying pathology, tuberousxanthomas being strongly associated with homozygous familial hypercholesterolaemia, an extremely rare condition. Its early detection provides a therapeutic window to prevent accelerated atherosclerosis and mortality. We present the case of a patient who started at two years with tuberous xanthomas, which were the diagnostic clue to identify the underlying homozygous familial hypercholesterolaemia.

Caracterización epidemiológica de pacientes diabéticos e hipertensos en consultorio en Quinta Normal, 2018-2019 / Epidemiological features of patients ascribed to a primary care cardiovascular health program in Santiago, Chile

BACKGROUND: Hypertension and diabetes are highly prevalent conditions in Chilean adults. AIM: To describe the demographic and clinical profiles, risk factors and complications associated with arterial hypertension (AH) and diabetes mellitus (DM) in patients ascribed to a cardiovascular health program at a public primary health care center in Santiago. MATERIAL AND METHODS: Review of medical records of 583 patients aged 37 to 95 years (56% women). Gender, age, smoking habits, blood pressure, glycated hemoglobin levels, LDL cholesterol and triglycerides levels, nutritional status in the last control carried out, and associated cardiovascular complications were recorded. RESULTS: Thirty four percent (201 participants) and 36% (210 participants) had a decompensated DM and AH, respectively. Dyslipidemia was the main associated cardiovascular risk factor. The prevalence of obesity was 43% (249 participants). Twenty percent had chronic kidney disease and 13% had diabetic retinopathy. CONCLUSIONS: These patients have a high frequency of obesity, dyslipidemia, and chronic kidney disease.

Polymorphisms of the Vitamin D Receptor Gene and Sex-Differential Associations with Lipid Profiles in Chinese Han Adults / 生物医学与环境科学（英文）

OBJECTIVE@#To explore the association of single nucleotide polymorphisms (SNPs) of the vitamin D receptor gene ( VDR) with circulating lipids considering gender differences.@*METHODS@#Of the Han Chinese adults recruited from a health examination center for inclusion in the study, the circulating lipids, 25-hydroxyvitamin D (25OHD), and other parameters were measured. The VDR SNPs of Cdx2 (rs11568820), Fok1 (rs2228570), Apa1 (rs7975232), and Taq1 (rs731236) were genotyped with a qPCR test using blood DNA samples, and their associations with lipids were analyzed using logistic regression.@*RESULTS@#In the female participants ( n = 236 with dyslipidemia and 888 without dyslipidemia), multiple genotype models of Fok1 indicated a positive correlation of B (not A) alleles with LDLC level ( P < 0.05). In the male participants ( n = 299 with dyslipidemia and 564 without dyslipidemia), the recessive model of Cdx2 and the additive and recessive models of Fok1 differed ( P < 0.05) between the HDLC-classified subgroups, respectively, and Fok1 BB and Cdx2 TT presented interactions with 25OHD in the negative associations with HDLC ( P < 0.05).@*CONCLUSION@#In the Chinese Han adults included in the study, the Fok1 B-allele of VDR was associated with higher LDLC in females, and the Fok1 B-allele and the Cdx2 T-allele of VDR were associated with lower HDLC in males. The interaction of VD and Fok1 BB or Cdx2 TT in males synergistically decreased HDLC levels.

Danlou Tablet Improves Chronic Intermittent Hypoxia-Induced Dyslipidemia and Arteriosclerosis by HIF-1α-Angptl4 mRNA Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To detect whether Danlou Tablet (DLT) regulates the hypoxia-induced factor (HIF)-1α-angiopoietin-like 4 (Angptl4) mRNA signaling pathway and explore the role of DLT in treating chronic intermittent hypoxia (CIH)-induced dyslipidemia and arteriosclerosis.@*METHODS@#The mature adipocytes were obtained from 3T3-L1 cell culturation and allocated into 8 groups including control groups (Groups 1 and 5, 0.1 mL of cell culture grade water); DLT groups (Groups 2 and 6, 0.1 mL of 1,000 µg/mL DLT submicron powder solution); dimethyloxalylglycine (DMOG) groups (Groups 3 and 7, DMOG and 0.1 mL of cell culture grade water); DMOG plus DLT groups (Groups 4 and 8, DMOG and 0.1 mL of 1,000 µg/mL DLT submicron powder solution). Groups 1-4 used mature adipocytes and groups 5-8 used HIF-1 α-siRNA lentivirus-transfected mature adipocytes. After 24-h treatment, real-time polymerase chain reaction and Western blot were employed to determine the mRNA and protein expression levels of HIF-1 α and Angptl4. In animal experiments, the CIH model in ApoE-/- mice was established. Sixteen mice were complete randomly divided into 4 groups including sham group, CIH model group [intermittent hypoxia and normal saline (2 mL/time) gavage once a day]; Angptl4 Ab group [intermittent hypoxia and Angptl4 antibody (30 mg/kg) intraperitoneally injected every week]; DLT group [intermittent hypoxia and DLT (250 mg/kg) once a day], 4 mice in each group. After 4-week treatment, enzyme linked immunosorbent assay was used to detect the expression levels of serum total cholesterol (TC) and triglyceride (TG). Hematoxylin-eosin and CD68 staining were used to observe the morphological properties of arterial plaques.@*RESULTS@#Angptl4 expression was dependent on HIF-1 α, with a reduction in mRNA expression and no response in protein level to DMOG or DLT treatment in relation to siHIF-1 α -transfected cells. DLT inhibited HIF-1 α and Angptl4 mRNA expression (P<0.05 or P<0.01) and reduced HIF-1 α and Angptl4 protein expressions with DMOG in mature adipocytes (all P<0.01), as the effect on HIF-1 α protein also existed in the presence of siHIF-1 α (P<0.01). ApoE-/- mice treated with CIH had increased TG and TC levels (all P<0.01) and atherosclerotic plaque. Angptl4 antibody and DLT both reduce TG and TC levels (all P<0.01), as well as reducing atherosclerotic plaque areas, narrowing arterial wall thickness and alleviating atherosclerotic lesion symptoms to some extent.@*CONCLUSION@#DLT had positive effects in improving dyslipidemia and arteriosclerosis by inhibiting Angptl4 protein level through HIF-1 α-Angptl4 mRNA signaling pathway.
