Advances in the study of congenital immune mechanisms mediated by modifiable cardiovascular risk factors for atherosclerosis / 中国胸心血管外科临床杂志

@#Obesity, sleep disorders, psychological stress, sedentary are modifiable cardiovascular risk factors. There is growing evidence that these risk factors may accelerate the chronic inflammatory process of atherosclerosis and lead to myocardial infarction. Studies on the role of immune cells and their related immune mechanisms in atherosclerosis have shown that the above modifiable risk factors can affect the hematopoiesis of the bone marrow system, affect the production of immune cells and phenotypes, and then affect the progress of atherosclerosis. This review will focus on the effects of modifiable cardiovascular risk factors on the progression of atherosclerosis through the role of the innate immune system.

Sleep quality analysis in individuals with acute coronary syndrome / Análisis de la calidad del sueño en individuos con síndrome coronario agudo / Análise da qualidade do sono em indivíduos com síndrome coronariana aguda

ABSTRACT Objective: to assess the prevalence of sleep disturbances and factors associated with sleep quality in patients with Acute Coronary Syndrome. Method: this is a cross-sectional study, carried out in the Cardiology Unit of a public university hospital, from October 2021 to December 2022, with patients hospitalized for Acute Coronary Syndrome over 18 years old. Sociodemographic and clinical data were collected, and sleep quality was measured by the Pittsburgh Sleep Quality Index. Statistical association tests were performed, considering a value of p<0.05 as significant. Results: a total of 96 patients were included, the majority being male, married and with a mean age of 63 years. The most prevalent comorbidities were hypertension, dyslipidemia and diabetes. It was identified that 92% had alteration in sleep quality and that the number of hours slept (p.<0.01), time to start sleep (p.0.03), sleep latency (p.<0.01), sleep duration (p.<0.01), habitual sleep efficiency (p.<0.02) and daytime sleepiness and daytime dysfunction (p.0.01) were significantly associated with sleep quality. There was a weak but significant correlation between age (r-0.22, p.0.02) and the presence of obstructive coronary lesions (r-0.23; p.0.02) with the Pittsburgh Sleep Quality Index score. Conclusion: most patients with acute coronary syndrome were classified as poor sleepers, therefore educational interventions to promote sleep should be performed in this population to reduce cardiovascular risk.

RESUMEN Objetivo: evaluar la prevalencia de trastornos del sueño y factores asociados a la calidad del sueño en pacientes con Síndrome Coronario Agudo. Método: estudio transversal, realizado en la Unidad de Cardiología de un hospital universitario público, de octubre de 2021 a diciembre de 2022, con pacientes hospitalizados por Síndrome Coronario Agudo mayores de 18 años. Se recogieron datos sociodemográficos y clínicos, y la calidad del sueño se midió mediante el Índice de Calidad del Sueño de Pittsburgh. Se realizaron pruebas de asociación estadística, considerando significativo un valor de p<0,05. Resultados: se incluyeron 96 pacientes, la mayoría hombres, casados ​​y con una edad media de 63 años. Las comorbilidades más prevalentes fueron hipertensión arterial sistémica, dislipidemia y diabetes. Se identificó que el 92% presentaba cambios en la calidad del sueño y que la cantidad de horas dormía (p.<0,01), tiempo de inicio del sueño (p.0,03), latencia del sueño (p.<0,01), duración del sueño (p.<0,01), eficiencia del sueño (p.<0,02) y somnolencia diurna y disfunción diurna (p.0,01) se asociaron significativamente con la calidad del sueño. Hubo una correlación débil pero significativa entre la edad (r-0,22, p.0,02) y la presencia de lesiones coronarias obstructivas (r-0,23; p.0,02) con el puntaje del Pittsburgh Sleep Quality Index. Conclusión: la mayoría de los pacientes con Síndrome Coronario Agudo fueron clasificados como insomnes, por lo que se deben realizar intervenciones educativas para promover el sueño en esta población para reducir el riesgo cardiovascular.

Houve correlação fraca, porém, significativa entre a idade (r-0,22, p.0,02) e a presença de lesões obstrutivas coronarianas (r-0,23; p.0,02) com o escore do Pittsburgh Sleep Quality Index. Conclusão: a maioria dos pacientes com Síndrome Coronariana Aguda foram classificados como maus dormidores, portanto intervenções educativas para promoção do sono devem ser realizadas nesta população para a redução no risco cardiovascular.

Síndrome metabólico y su correlación con ecuaciones de predicción del riesgo global de enfermedad cardiovascular / Metabolic Syndrome and its Correlation with Prediction Equations of Global Risk for Cardiovascular Disease

Introducción: El síndrome metabólico constituye un hito en la investigación de evaluar mejor y de manera óptima el riesgo de enfermedad cardiovascular aterosclerótica. Objetivo: Analizar la correlación entre la capacidad predictiva del riesgo global de enfermedad cardiovascular aterosclerótica del síndrome metabólico y las tablas de riesgo: Framingham Risk Score, la tabla de la OMS/ISH y las de Gaziano, la ecuación PROCAM y el algoritmo QRISK2. Métodos: Se realizó una revisión documental, para lo cual se empleó la bibliografía nacional e internacional, especialmente la publicada en los últimos 5 años. Se utilizó el motor de búsqueda Google Académico y se consultaron artículos de libre acceso en las bases de datos Pubmed y SciELO desde marzo 2020 hasta el mes de enero 2021. Se emplearon como palabras clave: síndrome metabólico, riesgo cardiovascular global, método de estimación de riesgo y sus equivalentes en inglés. Las unidades de análisis fueron artículos originales, de revisión, incluyendo revisiones sistemáticas publicadas en los idiomas español e inglés. Fueron seleccionados 38 artículos (23 en idioma español, 15 en inglés) y 31 (81,5 por ciento) corresponden a los últimos 5 años. Conclusiones: El síndrome metabólico y los sistemas de estimación del riesgo global de enfermedad cardiovascular aterosclerótica no deben ser utilizados como equivalentes a causa de que su concordancia, en sentido general, es muy cuestionable. No obstante, se puede considerar como una herramienta útil en prevención primaria de la enfermedad cardiovascular aterosclerótica, siempre y cuando no sustituyan el juicio clínico y se contemplen todas las excepciones y precauciones posibles en el momento de su aplicación(AU)

Introduction: Metabolic syndrome is a milestone within the research to assess better and optimally the risk of atherosclerotic cardiovascular disease. Objective: To analyze the correlation between the predictive capacity for the global risk of atherosclerotic cardiovascular disease of metabolic syndrome and the risk tables: Framingham Risk Score, the WHO/ISH and Gaziano tables, the PROCAM equation, and the QRISK2 algorithm. Methods: A documentary review was carried out, using national and international literature, especially published within the last five years. The Google Scholar search engine was used and open-access articles were consulted in the Pubmed and SciELO databases, from March 2020 to January 2021. The keywords used were síndrome metabólico [metabolic syndrome], riesgo cardiovascular global [global cardiovascular risk], método de estimación de riesgo [risk estimation method] and their English equivalents. The units of analysis were original review articles, including systematic reviews published in Spanish and English. Thirty-eight articles were selected (23 in Spanish and fifteen in English), 31 (81.5 percent) of which correspond to the last five years. Conclusions: Metabolic syndrome and global risk estimation systems for atherosclerotic cardiovascular disease should not be used as equivalents because their concordance, in general, is very questionable. Nevertheless, they can be considered a useful tool in the primary prevention of atherosclerotic cardiovascular disease, as long as they do not replace clinical judgment and all possible exceptions or precautions are considered at the time of their application(AU)

Factores de riesgo cardiovascular en familiares de primer grado de mujeres con síndrome de ovario poliquístico / Cardiovascular Risk Factors in First-Degree Relatives of Women with Polycystic Ovary Syndrome

Introducción: El síndrome de ovario poliquístico es una entidad que, más allá de las afectaciones reproductivas que lo caracterizan, constituye un factor de riesgo de enfermedad cardiovascular. Esto último, adquiere mayor relevancia debido a que ha aumentado en la mujer que padece el síndrome y también en sus familiares. Objetivo: Demostrar que los familiares de primer grado de las mujeres con el síndrome de ovario poliquístico tienen mayor frecuencia de trastornos del metabolismo hidrocarbonado, dislipidemia y resistencia a la insulina. Métodos: Se realizó un estudio descriptivo transversal con 36 familiares de primer grado de mujeres con y sin síndrome de ovario poliquístico. Se les realizó un examen físico para comprobar el peso, la talla y la tensión arterial para descartar hipertensión en el momento de la inclusión. Resultados: La media del índice HOMA-IR en el grupo de estudio fue de 3,3 y en el de control 2,4. La prueba de tolerancia a la glucosa de 2 horas diagnosticó una glucosa alterada en ayunas a 9 familiares, 5 (55,6 por ciento) del grupo de estudio y 4 (44,4 por ciento), del grupo control. Hubo 7 familiares a los que se les detectó una tolerancia a la glucosa alterada, 6 (85,7 por ciento) familiares de mujeres con el síndrome y 1 (14,3 por ciento), del grupo control. Conclusiones: Los factores de riesgo cardiovasculares clásicos estudiados son más frecuentes en los familiares de mujeres con síndrome de ovario poliquístico que en los familiares de mujeres sin dicha enfermedad(AU)

Introduction: Polycystic ovary syndrome is an entity that, beyond the reproductive affectations that characterize it, constitutes a risk factor for cardiovascular disease. This aspect acquires greater relevance because the associated entity is not only increasing among the women who suffers from the syndrome, but also among their family members. Objective: To show that first-degree relatives of women with polycystic ovary syndrome present a higher frequency of carbohydrate metabolism disorders, dyslipidemia and insulin resistance. Methods: A cross-sectional and descriptive study was carried out with 36 first-degree relatives of women with and without polycystic ovary syndrome. They underwent physical examination to check their weight, height and blood pressure, in order to rule out hypertension at the time of inclusion. Results: The mean HOMA-IR index was 3.3 in the study group and 2.4 in the control group. The two-hour glucose tolerance test permitted to diagnose impaired fasting glucose in nine relatives, five (55.6 percent) from the study group and four (44.4 percent) from the control group. Seven relatives were reported with impaired glucose tolerance, six (85.7 percent) relatives of women with the syndrome and one (14.3 percent) from the control group. Conclusions: The classic cardiovascular risk factors studied are more frequent in the relatives of women with polycystic ovary syndrome than in the relatives of women without this disease(AU)

Prevalência de fatores de risco coronariano e prontidão para atividade física em mulheres praticantes de caminhada e corrida recreativa / Prevalence of coronary risk factors and readiness for physical activity in women practicing walking and recreational running

Este estudo objetivou determinar a prontidão para atividade física e a prevalência de fatores de risco coronariano em mulheres praticantes de caminhada e corrida recreativa, através da aplicação dos questionários PAR-q e RISKO. Participaram do estudo 80 mulheres, as quais foram divididas em quatro grupos etários (G1 = 20-29 anos; G2 = 30-39 anos; G3 = 40-49 anos; G4 = 50-59 anos). Adotou-se com o critério de inclusão mulheres que praticassem caminhada e/ou corrida de forma recreativa há pelo menos dois meses sem orientação de um profissional de Educação Física, com frequência mínima de três vezes por semana. Utilizaram-se os questionários PAR-q, para determinar a prontidão para a prática de atividade física, e RISKO, para identificar os fatores de risco coronariano. Em relação ao PAR-q, 32,5% da amostra respondeu positivamente a, pelo menos, uma questão, apresentando inaptidão para atividade física . A questão com maioríndice de respostas positivas foi relacionada a episódios de tontura, correspondendo a 18,8% da amostra. O G3 apresentou maior prevalência em comparação aos demais grupos. O escore médio de risco coronariano obtido foi de 15,22 ± 3,29 pontos (risco abaixo da média), correspondendo a 66,3% da amostra. Foram encontrados valores maiores nas avaliadas do G4. A questão com maior escore foi relacionada à hereditariedade, correspondendo a 63,8% das entrevistadas, seguida de sexo e sobrepeso. Conclui-se que os grupos com maior faixa etária tiveram maior prevalência em respostas positivas no questionário PAR-q. No tocante ao RISKO, a maioria da amostra foi classificada como risco abaixo da média, sendo os fatores hereditariedade, sexo e sobrepeso os de maior prevalência...(AU)

This study aimed to determine the physical activity readiness and the coronary risk prevalence in women practicing walking and recreational running, through the application of PAR-q and RISKO questionnaires. 80 women participated in this study, divided in four age groups (G1 = 20-29 years old; G2 = 30-39 years old; G3 = 40-49 years old; G4 = 50-59 years old). We adopted as inclusion criterion women who practiced waking and/or recreational running for at least two months, without orientation of a physical educator, with minimal frequency of 3 times per week. We used PAR-q questionnaires to determine the readiness for practicing physical activity, and RISKO, to identify the coronary risk factors In relation to PAR-q, 32.5% of the sampleanswered positively to at least one question, showing inaptitude to physical activity. The question with highest index of positiveanswers wasrelated to dizziness episodes, corresponding to 18.8% of the sample. G3 presented a higher prevalence in relation to the oth er gro ups. The average score for coronary risk was 15.22 ± 3.29 points(below the average risk), correspo ndingto 66.3% of the sample. Higher values were found in G4 age group. Thequestion with the highestscore was the one related to heredity, corresponding to 63.8% of the subjects; followed by sex and overweight. Thus, we concluded that the groups with higher age had higher prevalence in positive answers in PAR-q questionnaire. Regarding RISKO questionnaire, most of sample was classified as below average risk, thus heredity, sex and overweight are the factors with higher prevalence...(AU)

Risk factors for cardiovascular disease in HIV/AIDS patients treated with highly active antiretroviral therapy (HAART) in the central-southern region of the state of Paraná - Brazil / Fatores de risco para doença cardiovascular em pacientes com HIV / AIDS tratados com terapia antirretroviral altamente ativa (HAART) na região centro-sul do estado do Paraná-Brasil

Abstract The aim of this study was to describe metabolic changes in HIV/AIDS patients according to the treatment regimen. It was a retrospective cohort conducted from 2002 to 2014. Researchers surveyed clinical variables and treatment regimen of 538 individuals. They used measures of central tendency and marginal logistic regression to determine the influence of the treatment regimen on clinical variables over time; survival was estimated using Kaplan-Meier curves. 56.2% of patients were male, 82.2% white, 33.8% had 4 to 7 years of study, 49.2% were married, 98.5% had sexual transmission, and 89.0% were heterosexuals. During the study period, 24.4% had hypertension, 18.2% changed cholesterol, 39.7% low HDL, 51.3% high triglycerides and 33.3% hyperglycemia. Treatment regimens with nucleotide reverse transcriptase inhibitors associated with protease inhibitors, and the association of different classes of antiretrovirals have been associated with greater lipid changes. Higher metabolic changes were observed in patients with longer treatment time. It is concluded that preventive measures, as well as early treatment, can contribute to minimize the risks of developing cardiovascular diseases.

Association between Lipoprotein (a) Levels and Metabolic Syndrome in a Middle-aged and Elderly Chinese Cohort / 生物医学与环境科学（英文）

OBJECTIVE@#The association between lipoprotein (a) [Lp(a)] levels and metabolic syndrome (MetS) remains uncertain, especially in the Asian population. The purpose of this study was to demonstrate the association between Lp(a) levels and MetS in a middle-aged and elderly Chinese cohort.@*METHODS@#A cross-sectional study of 10,336 Chinese adults aged 40 years or older was conducted in Jiading District, Shanghai, China. Logistic regression analysis was used to evaluate the association between serum Lp(a) levels and MetS.@*RESULTS@#In the overall population, 37.5% of participants had MetS. Compared with individuals in the lowest quartile of serum Lp(a) levels, those in the highest quartile had a lower prevalence of MetS (30.9% vs. 46.9%, P for trend < 0.0001). Multivariate logistic regression analyses showed that compared with participants in the bottom quartile of serum Lp(a) levels, those in the top quartile had decreased odds ratio (OR) for prevalent MetS [multivariate-adjusted OR 0.45 (95% confidence interval 0.39-0.51); P < 0.0001]. Additionally, Lp(a) level was conversely associated with the risk of central obesity, high fasting glucose, high triglycerides, and low HDL cholesterol, but not with hypertension. Stratified analyses suggested that increasing levels of Lp(a) was associated with decreased risk of MetS in all the subgroups.@*CONCLUSION@#Serum Lp(a) level was inversely associated with the risk of prevalent MetS in a middle-aged and elderly Chinese cohort.

Different level of fasting blood glucose and cardiovascular risk factors clustering among population of Jiangsu Province / 中华疾病控制杂志

Objective To analyze the clustering of major cardiovascular risk factors among population with different level of fasting blood glucose (FBG) in Jiangsu provincial communities. Methods A population-based screening project was conducted during 2015-2017, with 83 522 residents aged 35-75 years from 6 areas included in the study. Prevalence and the clustering of four cardiovascular risk factors (hypertension, obesity, dyslipidemia and smoking) were analyzed. Binary Logistic regression analysis was performed to explore the relationship between FBG and cardiovascular risk factor clustering. Results The prevalence of diabetes was 18.9% among adults aged 35-75 years in Jiangsu province, and 41.4% of them were aware of their disease. Among undiagnosed population, the odd ratios (OR) of cardiovascular risk factors clustering in impaired fasting glucose (IFG) and hyperglycemia group was 1.29 (OR=1.29，95% CI:1.24-1.36，P<0.001) and 1.99 (OR=1.99，95% CI:1.89-2.08，P<0.001), compared with normal FBG group. The control rate of FBG was 15.5% among diagnosed cases. There was no difference in the risk clustering between diabetes patient with and without control of FBG. Conclusions Hyperglycemia and IFG increase the risk of cardiovascular risk factor clustering. Comprehensive interventions should be served as an important role to keep blood glucose at a normal level in high-risk population.

Prevalence and factors associated with metabolic syndrome in 6-10-year-old children

Abstract Aims: to identify the prevalence of metabolic syndrome (MetS) and associated risk factors in children. Methods: a total of 1,480 Brazilian children aged 6-10 years old (52.2% girls) participated in this population-based, epidemiological cross-sectional study. The inclusion criteria were children born between the years 2001 and 2006, of both sexes, who did not use remedy, were not on a calorie restriction diet, and who respected the 12-hour fast for blood collection. Anthropometric measurements, blood pressure, blood collection, and completion of the Previous Day Food Questionnaire and interview using a Physical Activity List were held at school. Parents were asked to complete a questionnaire on socioeconomic status and lifestyle habits of their child. Chi-square test compared proportions and factors associated with MetS were identified using Poisson Regression. Results: Girls had significantly higher MetS prevalence compared with boys (12.6% vs. 8.5%, p=0.046). After multivariable analysis, body fat percentage (p=0.001), fat mass (p<0.001), lean body mass (p< 0.001) and sedentary behavior (p= 0.050) were positively associated with MetS. Conclusions: Modifiable factors such as body fat percentage, fat mass, lean body mass and sedentary behavior were associated with MetS in children. Thus, interventions targeted for weight management, and adopting healthy habits such as reducing time in front of TV/computer/video game need to be part of the lifestyle of children.(AU)

Cardiovascular risk factors and cognitive performance in aging / Fatores de risco cardiovascular e desempenho cognitivo no envelhecimento

ABSTRACT. Background. Atherosclerosis in cerebral blood vessels, especially those which compose the Circle of Willis, can lead to reduced supply of oxygen and nutrients to different cortical structures, affecting cognitive function. Objective: To analyze whether cardiovascular risk factors negatively influence cognitive performance in adults and elderly. Methods: One hundred twenty-nine participants of both sexes, aged over 50 years, without cognitive or functional impairment were included. Body mass index (BMI), hypertension (HTN), diabetes mellitus (DM), smoking history, plasma levels of total cholesterol, low density lipoproteins (LDL), high density lipoproteins (HDL) and very low density lipoproteins (VLDL) cholesterol, triglycerides, and glucose were the cardiovascular risk factors analyzed. Cognitive assessment was performed using tests of attention, working memory, category fluency and declarative memory. Results: Controlling for age and education, multivariate linear regression models revealed that higher concentrations of triglycerides, as well as total, LDL and VLDL cholesterol, were associated with poorer performance on the digit span and category fluency tests. Higher HDL concentrations were associated with higher scores on category fluency tasks. Furthermore, higher BMI was associated with poorer delayed recall performance. Conclusion: The findings revealed that cardiovascular risk factors may negatively impact cognitive performance in aging.

RESUMO. Introdução: A aterosclerose nos vasos sanguíneos cerebrais, especialmente naqueles que compõem o Círculo de Willis, pode levar à redução da oferta de oxigênio e nutrientes para diferentes estruturas corticais, afetando a função cognitiva. Objetivo: Analisar se fatores de risco cardiovascular influenciam negativamente o desempenho cognitivo em adultos e idosos. Métodos: Foram incluídos cento e vinte e nove participantes de ambos os sexos, com idade superior a 50 anos, sem comprometimento cognitivo ou funcional. Índice de massa corporal (IMC), hipertensão arterial (HAS), diabetes mellitus (DM), história de tabagismo, níveis plasmáticos de colesterol total e lipoproteínas de baixa densidade (LDL), lipoproteínas de alta densidade (HDL) e lipoproteínas de baixa densidade (VLDL), triglicerídeos e glicemia foram os fatores de risco cardiovascular analisados. A avaliação cognitiva foi realizada utilizando testes de atenção, memória operacional, fluência verbal e memória declarativa. Resultados: Controlando para idade e escolaridade, os modelos de regressão linear multivariada revelaram que concentrações mais elevadas de triglicerídeos, bem como colesterol total, LDL e VLDL, estão associadas com pior desempenho nos testes de extensão de dígitos e fluência verbal. Além disso, concentrações maiores de HDL se correlacionaram com pontuações maiores nas tarefas de fluência verbal. IMC maior se associou com menor desempenho na evocação tardia. Conclusão: Os achados revelaram que fatores de risco cardiovascular podem afetar negativamente o desempenho cognitivo durante o envelhecimento.

Dislipidemia aterogénica en Latino América: prevalencia, causas y tratamiento / Atherogenic dislipidemia in Latin America: prevalence, causes and treatment

En las guías clínicas actuales, la dislipidemia aterogénica (DA) es una entidad escasamente atendida. Debido a las frecuentes alteraciones en los lípidos asociados a la DA en Latino América (LA), se organizó un grupo de expertos que se ha denominado Academia Latino Americana para el estudio de los Lípidos (ALALIP) para generar un documento con análisis de su prevalencia y ofrecer recomendaciones prácticas. Se utilizó la metodología Delphi modificada, con revisión comprensiva de la literatura con énfasis en aquellas publicaciones con implicaciones para LA. Subsecuentemente, se desarrollaron preguntas claves para ser discutidas. En LA no existe un estudio global sobre los factores de riesgo que representan a la totalidad de la población. El análisis sistemático de las encuestas nacionales de salud y de los estudios sistemáticos de cohorte muestran consistentemente una alta prevalencia de las anormalidades lipídicas que definen la DA. La concentración baja del colesterol unido a las lipoproteínas de alta densidad (C-HDL) varía entre 34,1% a 53,3% y la de triglicéridos (TG) elevados del 25,5% al 31,2%, con mayor prevalencia entre los hombres. Múltiples causas se han reconocidos, como alta ingesta de alimentos de mayor densidad calórica, contenido de colesterol, grasas trans, sedentarismo y cambios epigenéticos. La DA bien puede ser tratada con los cambios terapéuticos del estilo de vida (CTEV) con incremento en la actividad física, ejercicio regular y dieta baja en carbohidratos y alta en ácidos grasos poliinsaturados, tales como los ácidos grasos omega-3 como intervención primaria. De ser necesario, esta estrategia sera suplementada con terapia farmacológica como la monoterapia con estatinas o la combinación de fibratos/ácidos grasos omega-3. Las anormalidades lipídicas que definen la DA tienen una elevada prevalencia en LA; su interacción con un estilo de vida no saludable, herencia y cambios epigenéticos están ligados a sus posibles causas. La DA es una causa importante de riesgo cardiovascular residual (RCVR) que debe ser diagnosticada y tratada. Es importante y necesario diseñar un estudio global de factores de riesgo en LA para conocer la real prevalencia de la DA.

In the current clinical guidelines, atherogenic dyslipidemia (AD) is a poorly recognized entity. Due to the frequent lipid alterations associated with AD in Latin America (LA), we organized a group of experts named Latin American Academy for the study of Lipids (ALALIP), to generate a document for analyzing its prevalence and to offer practical recommendations. Using the Delphi methodology, we conducted a comprehensive literature review, with emphasis on those publications with implications for LA. Subsequently we developed key questions to be discussed. In LA there is no a global study on risk factors that represent the entire population. The systematic analysis of national health surveys and regional cohort studies showed a consistent high prevalence of the lipid abnormalities that define AD. Low high density lipoprotein cholesterol (HDL-C) ranges from 34.1% to 53.3% and elevated triglycerides (TG) from 25.5% to 31.2%, more prevalent in men. There are multiple causes: high consumption of foods with a high caloric density, cholesterol and trans fats, sedentary lifestyle and epigenetic changes. AD must be well treated with therapeutic changes in lifestyle with increased in physical activities, regular exercise and a diet with a low proportion of carbohydrates y rich in poliunsatured fatty acid, such as omega-3 fatty acid as primary intervention. If needed, this strategie must be supplemented with pharmacological therapies such as monotherapy with statins or a combination of fibrates plus omega-3.fatty acid. Lipid abnormalities that define AD have a high prevalence in LA; the interaction between non-healthy lifestyle, inheritance and epigenetic changes, possibly are its cause. AD is an important cause of cardiovascular residual risk (CVRR), that must be diagnosed and treated. It is important and neccesary to design a global study of risk factors in LA to know the true prevalence of AD.

Objetivo: La paraoxonasa 1 (PON1), una esterasa asociada a las lipoproteínas de alta densidad (HDL), presenta diversos polimorfismos: el polimorfismo PON1 Q192R (región codificante) es el responsable de las variaciones de la actividad paraoxonasa de la enzima. El alelo PON1 192R es considerado un factor de riesgo para desarrollar trastornos cardiometabólicos en algunas poblaciones. El objetivo del presente estudio es determinar la distribución de los polimorfismos PON1 Q192R, y su asociación con el perfil lipidíco y APO A1 en una población andina. Materiales y métodos: Estudio descriptivo, transversal, en el que participaron 79 personas adultas (26 hombres y 53 mujeres), clínicamente sanas, residentes del distrito de Junín a 4105 msnm. Se empleó la técnica PCR/RFLP para el análisis del sitio polimórfico Q192R del gen PON1, y se determinaron los valores séricos del perfil lipídico y APO A1, y las actividades paraoxonasa y arilesterasa de la enzima. Resultados: La distribución de los genotipos para PON1192 fue: QQ 13,9%, QR 45,6% y RR 40,5%, y el alelo más frecuente fue 192R 63%. Las actividades paraoxonasa basal y estimulada fueron diferentes según sus genotipos, mientras que la actividad esterasa de la enzima no estuvo influenciada por el polimorfismo. Por otra parte, no se encontró asociación entre el polimorfismo PON1 Q192R y el perfil lipídico y APO A1. Conclusiones: La alta prevalencia del alelo PON1 192R en la población estudiada probablemente indique un papel importante en el desarrollo de enfermedades cardiometabólica

Objective: Paraoxonase 1 (PON1), an esterase associated with high-density lipoproteins (HDL), has several polymorphisms: the PON1 Q192R polymorphism (coding region) is responsible for variations in the paraoxonase activity of the enzyme. The PON1 192R allele is considered a risk factor for developing cardiometabolic disorders in some populations. The aim of the present study is to determine the distribution of the PON1 Q192R polymorphism and its association with the lipid profile and APO A1 in an Andean population. Materials and methods: A descriptive, cross-sectional study involving 79 healthy adults (26 males and 53 females), residents of the district of Junín at 4105 m.a.s.l. The PCR/RFLP technique was used for the analysis of the PON1 Q192R polymorphism. The serum values of the lipid profile and APO A1, and the paraoxonase and arylesterase activities of the enzyme were determined. Results: The distribution of the genotypes for PON1192 was QQ 13.9%, QR 45.6% and RR 40.5%, and the most frequent allele was 192R 63%. The baseline and stimulated paraoxonase activities were different based on their genotypes, while the esterase activity of the enzyme was not influenced by the polymorphism. On the other hand, no association was found between the PON1 Q192R polymorphism and the lipid profile and APO A1. Conclusions: The high prevalence of the PON1 192R allele among the studied population probably indicates an important role in the development of cardiometabolic diseases

A comparative study on the fasting and post prandial lipid levels as a cardiovascular risk factor in patients with type 2 diabetes mellitus

Background: Diabetes mellitus is a major independent risk factor for cardiovascular disease (CVD). Excess abdominal fat, assessed by measurement of waist to hip ratio, is independently associated with a higher risk for cardiovascular disease. Aim and objectives: To study the fasting and post prandial lipid levels in patients with type 2 diabetes mellitus and to assess the significance of post prandial dyslipidemia with respect to fasting dyslipidemia as cardiovascular risk factor in these patients. Materials and methods: The study was conducted on 100 patients from General Medicine ward and Diabetology OPD of Government Rajaji Hospital, Madurai, and 100 age and sex matched healthy subjects as controls during the period of March 2016 To August 2016. Subjects believed to fulfil all eligibility criteria, and none of the exclusion criteria were included in the study. A predesigned proforma was used to collect the demographic and clinical details of the patients and the controls. By Clinical examination abdominal obesity was measured by waist hip ratio WHR>.90 in men and WHR>.80 in women were taken as having significant cardiovascular risk. Laboratory investigations fasting Blood Sugar, 2hr Post Prandial Blood sugar, fasting lipid profile and 6 hours post prandial were done. Comparison of various parameters were done and significance assessed by Student t test. One way ANOVA, Pearson Correlation and Chi square test and P value of < 0.05 was taken as significant.

IAIM, 2017; 4(8): 72-76. Page 73 Results: Among the 100 cases of Type 2 Diabetes mellitus, by taking value of WHR 0.90 for males and 0.8 for females, the cardiovascular risk was assessed. 96 had cardiovascular risk (50 male, 46 females). By comparing with the standard reference values of the lipid profile out of the 100 diabetic subjects 53 had fasting dyslipidemia (29 males, 24 females) and 64 had post prandial dyslipidemia (23 males , 41 females). We observed a significant increase in both fasting as well as postprandial blood glucose levels in the Type 2 Diabetic subjects, as compared to those of their respective controls. Also, the postprandial blood glucose level was significantly increased as compared to that in the fasting state in the Type 2 Diabetic subjects but the HDL-cholesterol level was not significantly decreased in fasting as well as postprandial state in the Type 2 DM patients as compared to that of control subjects in our study. Conclusion: Persistent postprandial hypertriglyceridemia may result in a proatherogenic environment leading to atherosclerosis and macrovascular disease in type 2 diabetes subjects. LDL oxidation in the postprandial state seems to be affected by an acute increase in glycemia. Thus, oxidative modification of LDL may contribute to higher CVD risk among diabetic patients, and elevated levels of TG may contribute to the rapid LDL oxidation seen in Type 2 DM. Hence, it is important and beneficial to estimate the postprandial lipid profile, in addition to the fasting lipid profile, in the cardiovascular risk assessment in the patients with Type 2 DM.

Dislipidemia aterogénica en latino américa: prevalencia, causas y tratamiento / Atherogenic dyslipidemia in Latin America: prevalence, causes and treatment

En las guías clínicas actuales, la dislipidemia aterogénica (DA) es una entidad no muy atendida. Debido a las frecuentes alteraciones en los lípidos asociados a la DA en Latino América (LA). Métodos: organizamos un grupo de expertos denominado Academia Latino Americana para el estudio de los Lípidos (ALALIP) para así generar un documento con análisis de su prevalencia y recomendaciones terapéuticas prácticas. Se utilizó la metodología Delphi modificada, con una revisión integral de la literatura y énfasis en las publicaciones con implicaciones para LA. Subsecuentemente, desarrollamos preguntas claves para ser discutidas. Resultados: En Latinoamérica (LA) no existe un estudio global sobre los factores de riesgo que representan a la totalidad de la población. El análisis sistemático de las encuestas nacionales de salud y de los estudios sistemáticos de cohorte muestran consistentemente una alta prevalencia de las anormalidades lipídicas que definen la DA. La concentración baja del colesterol unido a las lipoproteínas de alta densidad (C-HDL) varía entre 34,1% a 53,3% y la de triglicéridos (TG) elevados del 25,5% al 31,2%, con mayor prevalencia entre los hombres. La DA bien puede ser tratada con los cambios del estilo de vida (CTEV) como ncremento en laactividad física, dieta baja en carbohidratos y alta en ácidos grasos poliinsaturados, tales como los ácidos grasos omega-3 como intervención primaria. De ser necesario, esta estrategia sera suplementada con terapia farmacológica como la monoterapia con estatinas o la combinación de fibratos/ácidos grasos omega-3. Conclusiones: Las anormalidades lipídicas que definen la DA tienen una elevada prevalencia en LA; su interacción con un estilo de vida no saludable, herencia y cambios epigenéticos están ligados a sus posibles causas. La DA es una causa importante de riesgo cardiovascular residual (RCVR) que debe ser diagnosticada y tratada. Es importante y necesario diseñar un estudio global de factores de riesgo en LA para conocer la real prevalencia de la DA(AU)

Due to the frequent lipid alterations associated with AD in Latin America (LA), we organized a group of experts named Latin American Academy for the study of Lipids (ALALIP), to generate a document to analize it´s prevalence and to offer practical recommendations. Methodology: Using the Delphi methodology, we conducted a comprehensive literature review, with emphasis on those publications with implications for LA. Subsequently we developed key questions to be discussed. Results: In LA There is no a global study on risk factors that represent the entire population. The systematic analysis of national health surveys and regional cohort studies showed a consistent high prevalence of the lipid abnormalities that define AD. Low high density lipoprotein cholesterol (HDL-C) ranges from 34.1% to 53.3% and elevated triglycerides (TG) from 25.5% to 31.2% more prevalent in men. There are multiple causes: high consumption of foods with a high caloric density, cholesterol and trans fats, sedentary lifestyle and epigenetic changes. AD must be well treated with therapeutic changes in lifestyle with increase in physical activities, regular exercise and a diet with a low proportion of carbohydrates and rich in poliunsatured fatty acid, such as omega-3 fatty acids as primary intervention. If needed, this strategy must be supplemented with pharmacological therapies such as monotherapy with statins or a combination of fibrates plus omega-3. fatty acid. conclusions: Lipid abnormalities that define AD have a high prevalence in LA; the interaction between non-healthy lifestyle, inheritance and epigenetic changes, possibly are the cause. AD is an important cause of cardiovascular residual risk (CVRR), that must be diagnosed and treated It is important and necesary to design a global study of risk factors in LA to know the true prevalence of AD(AU)

RETROSPECTIVE GASTRIC CANCER STUDY / Шинэ санаа Шинэ нээлт

@#BACKGROUND In Mongolia, Gastric cancer is second most common cancer. 904 (603-men, 301- women) new gastric cancer cases reported in 2016 and is about twice as common in men than women. The number of new gastric cancer cases was 29.3 per 100.000 men and women in Mongolia. A greater percentage of total gastric cancer cases were III, IV stage(85.5%). In 2016, The Orkhon province had the highest rate in Mongolia (54.3 cases per 100.000 men and women). In Mongolia and Orkhon province, gastric cancer remains an important public health problem. METHODS A total of 60 gastric cancer cases diagnosed at Medipas Hospital between March 2016 and October 2017 were analyzed retrospectively. RESULTS The average age of all gastric cancer patients was 59.75±9.91 years. The men to women ratio was 1:0.28. The most common location of gastric cancer was upper third(59.7%), followed by middle third (26.9%) and lower third (13.4%) of the stomach. Thepercentage of total gastric cancer cases were advanced gastric cancer (66.7%) than early gastric cancer (31.7%). And One case(1.6%) diagnosed MALT lymphoma. 55% of total gastric cancer cases were treated by Endoscopic submucosal dissection and Gastroectomy surgery. CONCLUSION One reason the overall survival rate is poor in the Mongolia is that most stomach cancers are diagnosed at an advanced rather than an early stage. The stage of the cancer has a major effect on a patient’s prognosis.

THE RELATIONSHIP BETWEEN ATHEROGENIC INDEX OF PLASMA AND RISKS OF CARDIOVASCULAR DISEASE / Шинэ санаа Шинэ нээлт

@#BACKGROUND: Cardiovascular diseases (CVDs) account for >17 million deaths globally each year and this figure is expected to grow to 23.6 million by 2030. According to the WHO report, one-third of ischemic heart disease is attributable to high cholesterol. There have been some claims that the atherogenic index of plasma (AIP), which is the logarithmic transformation of the just-mentioned ratio (TG/HDL-C), could be used as a significant predictor of atherosclerosis, and CVD as well. Thus, we aimed to study the relationship between AIP and cardiovascular risk factors. METHODS: The cross-sectional hospital based study was conducted including 117 participants aged between 40-72 years old without cardiovascular symptoms were recruited from Second General Hospital. After filled consent form, participants’ habits of smoking, alcohol usage, obesity, arterial hypertension and sedentary lifestyle were assessed through a structured questionnaire and physical examination. By using fully automated open-system analyzer, determinations of total cholesterol, triglycerides, low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C) three times and glucose twice were performed simultaneously and then their averages were calculated. At least one abnormal lipid level was considered as “dyslipidemia”. The atherogenic index of plasma (AIP) was calculated as the logarithmically transformed ratio of molar concentrations of TG to HDL-C. Statistical analysis was performed using SPSS 22. RESULTS: Of total 117 participants ranging 40-72 years old, 45.3% were male and 54.7% were female with mean age 53.6±0.79. Regarding cardiovascular risk factors, 63.8% were physically inactive, 32.48% were smokers, 47% were alcohol user, 48% were hypertensive, and 18.26% were diabetic. The mean values plus standard error of lipid components were 195.5±6.09 mg/dL in cholesterol, 181.25±27.36 mg/dL in triglycerides, 60.6±1.39 mg/dL in HDL-C, 138.5±3.74 mg/dL in LDL-C, 6.27±0.26 mmol/L in fasting glucose. The dyslipidemia was detected in 54.7% of total participants and mean level of AIP was 0.33±0.03 (min=-0.52; max=1.51). The mean levels of 10 year and lifetime risk were 6.25±0.63% (min=0.2; max=33.5) and 43±1.53% (min=7.5; max=69), respectively. AIP had weak correlations with gender, smoking, anti-hypertensive drug usage, aspirin usage, 10 year and lifetime risks of CVD, hypertension, fasting glucose, body mass index, and dyslipidemia (0.2<r<0.4, р<0.05). Multivariate regression revealed that fasting glucose level (β=0.016, Cl95%; 0.005:0.027, р=0.003) and BMI (β=0.092, Cl95%; 0.002:0.035, р=0.002) were associated with AIP. CONCLUSION: The prevalence of dyslipidemia is higher among the participants and cardiovascular risk factors affect AIP differently. Fasting glucose level as well as body mass index are potent risk factors to increase AIP.

Concurrent Low Brain and High Liver Uptake on FDG PET Are Associated with Cardiovascular Risk Factors

OBJECTIVE: Concurrent low brain and high liver uptake are sometimes observed on fluorine-18-labeled fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET). We investigated the potential clinical significance of this uptake pattern related to metabolic syndrome (MS). MATERIALS AND METHODS: We retrospectively reviewed data from 264 consecutive males who had undergone general health check-ups, including FDG PET/CT scans. After an overnight fast, the men had their peripheral blood drawn and the levels of various laboratory parameters measured; an FDG PET/CT scan was performed on the same day. We measured the maximum standardized uptake values of the brain and liver from regions of interest manually placed over the frontal cortex at the level of the centrum semiovale and the right lobe of the liver parenchyma, respectively. RESULTS: Fasting blood glucose (FBG; odds ratio [OR] = 1.063, p < 0.001) and glycated hemoglobin (HbA1c; OR = 3.634, p = 0.010) were the strongest predictive factors for low brain FDG uptake, whereas waist circumference (OR = 1.200, p < 0.001) and γ-glutamyl transpeptidase (OR = 1.012, p = 0.001) were the strongest predictive factors for high liver uptake. Eleven subjects (4.2%) showed concurrent low brain and high liver FDG uptake, and all but one of these subjects (90.9%) had MS. Systolic blood pressure, waist circumference, FBG, triglyceride, alanine aminotransferase, insulin resistance (measured by homeostasis model assessment), insulin, HbA1c, and body mass index were higher in subjects with this FDG uptake pattern than in those without (all, p < 0.001). CONCLUSION: Concurrent low brain and high liver FDG uptake were closely associated with MS. Moreover, subjects with this pattern had higher values for various cardiovascular risk factors than did those without.

The Value of Cardiovascular Risk Factors in Predicting Hearing Recovery of Sudden Sensorineural Hearing Loss / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Several prognostic factors are known to be related to the recovery of sudden sensorineural hearing loss (SSNHL). Recent studies have suggested that cardiovascular risk factors (CVRFs) are associated with the occurrence of SSNHL. However, the value of CVRFs as a predictor of recovery in patients with SSNHL has been rarely evaluated. We aim to evaluate the prognostic value of CVRFs in relation to hearing recovery of SSNHL. SUBJECTS AND METHOD: A total of 278 patients who were diagnosed and treated for SSNHL and who underwent blood sampling and follow-ups for more than 3 months were reviewed retrospectively. We reviewed CVRFs such as age, body mass index, blood pressure, cholesterol, smoking history, the presence of diabetes mellitus and other related underlying diseases. Patients were divided into three groups (low, medium, and high CVRF groups) according to the CVRF grades. Hearing thresholds were repeatedly measured on the initial visit, 1 week, 1 month and 3 months after treatment. Treatment outcome was analyzed by comparing hearing recovery rate and post-treatment audiometric changes among the three CVRF groups. RESULTS: Seventy (25.2%), 129 (46.4%) and 79 (28.4%) patients were included into the low, medium and high CVRF groups, respectively. The hearing threshold was significantly reduced at 3 months after treatment in all three groups (p<0.001). The hearing recovery rate of the low CVRF group was significantly higher than that of the medium and high CVRF group (p=0.011). On the last visit, the high CVRF group significantly showed more poor hearing improvement than the low CVRF group did (p=0.045). CONCLUSION: Our findings suggest that the presence of CVRFs may be a poor prognostic sign for hearing recovery in patients with SSNHL.
